-.SH NAME
-ftpd \- DARPA Internet File Transfer Protocol server
-.SH SYNOPSIS
-.B /etc/ftpd
-[
-.B \-d
-] [
-.B \-l
-] [
-.BR \-t timeout
-] [
-.BR \-T maxtimeout
-]
-.SH DESCRIPTION
-.I Ftpd
-is the DARPA Internet File Transfer Protocol
-server process. The server uses the TCP protocol
-and listens at the port specified in the ``ftp''
-service specification; see
-.IR services (5).
-.PP
-If the
-.B \-d
-option is specified,
-debugging information is written to the syslog.
-.PP
-If the
-.B \-l
-option is specified,
-each ftp session is logged in the syslog.
-.PP
-The ftp server
-will timeout an inactive session after 15 minutes.
-If the
-.B \-t
-option is specified,
-the inactivity timeout period will be set to
-.I timeout
-seconds.
-A client may also request a different timeout period;
-the maximum period allowed may be set to
-.I timeout
-seconds with the
-.B \-T
-option.
-The default limit is 2 hours.
-.PP
-The ftp server currently supports the following ftp
-requests; case is not distinguished.
-.PP
-.nf
-.ta \w'Request 'u
-\fBRequest Description\fP
-ABOR abort previous command
-ACCT specify account (ignored)
-ALLO allocate storage (vacuously)
-APPE append to a file
-CDUP change to parent of current working directory
-CWD change working directory
-DELE delete a file
-HELP give help information
-LIST give list files in a directory (``ls -lgA'')
-MKD make a directory
-MDTM show last modification time of file
-MODE specify data transfer \fImode\fP
-NLST give name list of files in directory
-NOOP do nothing
-PASS specify password
-PASV prepare for server-to-server transfer
-PORT specify data connection port
-PWD print the current working directory
-QUIT terminate session
-RETR retrieve a file
-RMD remove a directory
-RNFR specify rename-from file name
-RNTO specify rename-to file name
-SITE non-standard commands (see next section)
-SIZE return size of file
-STAT return status of server
-STOR store a file
-STOU store a file with a unique name
-STRU specify data transfer \fIstructure\fP
-SYST show operating system type of server system
-TYPE specify data transfer \fItype\fP
-USER specify user name
-XCUP change to parent of current working directory (deprecated)
-XCWD change working directory (deprecated)
-XMKD make a directory (deprecated)
-XPWD print the current working directory (deprecated)
-XRMD remove a directory (deprecated)
-.fi
-.PP
-The following non-standard or UNIX specific commands are supported
-by the SITE request.
-.PP
-.nf
-.ta \w'Request 'u
-\fBRequest Description\fP
-UMASK change umask. \fIE.g.\fP SITE UMASK 002
-IDLE set idle-timer. \fIE.g.\fP SITE IDLE 60
-CHMOD change mode of a file. \fIE.g.\fP SITE CHMOD 755 filename
-HELP give help information. \fIE.g.\fP SITE HELP
-.fi
-.PP
-The remaining ftp requests specified in Internet RFC 959 are
-recognized, but not implemented.
-MDTM and SIZE are not specified in
-RFC 959, but will appear in the next updated FTP RFC.
-.PP
-The ftp server will abort an active file transfer only when the
-ABOR command is preceded by a Telnet "Interrupt Process" (IP)
-signal and a Telnet "Synch" signal in the command Telnet stream,
-as described in Internet RFC 959.
-If a STAT command is received during a data transfer, preceded by a Telnet IP
-and Synch, transfer status will be returned.
-.PP
-.I Ftpd
-interprets file names according to the ``globbing''
-conventions used by
-.IR csh (1).
-This allows users to utilize the metacharacters ``*?[]{}~''.
-.PP
-.I Ftpd
-authenticates users according to three rules.
-.IP 1)
-The user name must be in the password data base,
-.IR /etc/passwd ,
-and not have a null password. In this case a password
-must be provided by the client before any file operations
-may be performed.
-.IP 2)
-The user name must not appear in the file
-.IR /etc/ftpusers .
-.IP 3)
-The user must have a standard shell returned by
-.IR getusershell (3).
-.IP 4)
-If the user name is ``anonymous'' or ``ftp'', an
-anonymous ftp account must be present in the password
-file (user ``ftp''). In this case the user is allowed
-to log in by specifying any password (by convention this
-is given as the client host's name).
-.PP
-In the last case,
-.I ftpd
-takes special measures to restrict the client's access privileges.
-The server performs a
-.IR chroot (2)
-command to the home directory of the ``ftp'' user.
-In order that system security is not breached, it is recommended
-that the ``ftp'' subtree be constructed with care; the following
-rules are recommended.
-.IP ~ftp)
-Make the home directory owned by ``ftp'' and unwritable by anyone.
-.IP ~ftp/bin)
-Make this directory owned by the super-user and unwritable by
-anyone. The program
-.IR ls (1)
-must be present to support the list command. This
-program should have mode 111.
-.IP ~ftp/etc)
-Make this directory owned by the super-user and unwritable by
-anyone. The files
-.IR passwd (5)
-and
-.IR group (5)
-must be present for the
-.I ls
-command to be able to produce owner names rather than numbers.
-The password field in
-.I passwd
-is not used, and should not contain real encrypted passwords.
-These files should be mode 444.
-.IP ~ftp/pub)
-Make this directory mode 777 and owned by ``ftp''. Users
-should then place files which are to be accessible via the
-anonymous account in this directory.
-.SH "SEE ALSO"
-ftp(1), getusershell(3), syslogd(8)
-.SH BUGS
-The anonymous account is inherently dangerous and should
-avoided when possible.
-.PP
-The server must run as the super-user
-to create sockets with privileged port numbers. It maintains
-an effective user id of the logged in user, reverting to
-the super-user only when binding addresses to sockets. The
-possible security holes have been extensively
-scrutinized, but are possibly incomplete.

-It then listens for connections on certain
-internet sockets. When a connection is found on one
-of its sockets, it decides what service the socket
-corresponds to, and invokes a program to service the request.
-After the program is
-finished, it continues to listen on the socket (except in some cases which
-will be described below). Essentially,
-.I inetd
-allows running one daemon to invoke several others,
-reducing load on the system.
-.PP
-Upon execution,
-.I inetd
-reads its configuration information from a configuration
-file which, by default, is
-.IR /etc/inetd.conf .
-There must be an entry for each field of the configuration
-file, with entries for each field separated by a tab or
-a space. Comments are denoted by a ``#'' at the beginning
-of a line. There must be an entry for each field. The
-fields of the configuration file are as follows:
-.br
- service name
-.br
- socket type
-.br
- protocol
-.br
- wait/nowait
-.br
- user
-.br
- server program
-.br
- server program arguments
-.PP
-The
-.I service name
-entry is the name of a valid service in
-the file
-.IR /etc/services/ .
-For ``internal'' services (discussed below), the service
-name
-.I must
-be the official name of the service (that is, the first entry in
-.IR /etc/services ).
-.PP
-The
-.I socket type
-should be one of ``stream'', ``dgram'', ``raw'', ``rdm'', or ``seqpacket'',
-depending on whether the socket is a stream, datagram, raw,
-reliably delivered message, or sequenced packet socket.
-.PP
-The
-.I protocol
-must be a valid protocol as given in
-.IR /etc/protocols .
-Examples might be ``tcp'' or ``udp''.
-.PP
-The
-.I wait/nowait
-entry is applicable to datagram sockets only (other sockets should
-have a ``nowait'' entry in this space). If a datagram server connects
-to its peer, freeing the socket so
-.I inetd
-can received further messages on the socket, it is said to be
-a ``multi-threaded'' server, and should use the ``nowait''
-entry. For datagram servers which process all incoming datagrams
-on a socket and eventually time out, the server is said to be
-``single-threaded'' and should use a ``wait'' entry. ``Comsat'' (``biff'')
-and ``talk'' are both examples of the latter type of
-datagram server.
-.I Tftpd
-is an exception; it is a datagram server that establishes pseudo-connections.
-It must be listed as ``wait'' in order to avoid a race;
-the server reads the first packet, creates a new socket,
-and then forks and exits to allow
-.I inetd
-to check for new service requests to spawn new servers.
-.PP
-The
-.I user
-entry should contain the user name of the user as whom the server
-should run. This allows for servers to be given less permission
-than root.
-The
-.I server program
-entry should contain the pathname of the program which is to be
-executed by
-.I inetd
-when a request is found on its socket. If
-.I inetd
-provides this service internally, this entry should
-be ``internal''.
-.PP
-The arguments to the server program should be just as they
-normally are, starting with argv[0], which is the name of
-the program. If the service is provided internally, the
-word ``internal'' should take the place of this entry.
-.PP
-.I Inetd
-provides several ``trivial'' services internally by use of
-routines within itself. These services are ``echo'',
-``discard'', ``chargen'' (character generator), ``daytime''
-(human readable time), and ``time'' (machine readable time,
-in the form of the number of seconds since midnight, January
-1, 1900). All of these services are tcp based. For
-details of these services, consult the appropriate RFC
-from the Network Information Center.
-.PP
-.I Inetd
-rereads its configuration file when it receives a hangup signal, SIGHUP.
-Services may be added, deleted or modified when the configuration file
-is reread.

- * This program invokes all internet services as needed.

- * Datagram oriented services are invoked when a datagram
- * arrives; a process is created and passed a pending message

- * the second type of server ``single-threaded''.
- *
- * Inetd uses a configuration file which is read at startup
- * and, possibly, at some later time in response to a hangup signal.

-README for UNIX NTP release $Date$ $Revision$
-
-
-
-NTP (Network Time Protocol) Daemons
-
- There are three programs in the NTP distribution:
- ntp - simple query program used for single
- sample queries
-
- ntpd - A daemon that sets up peers and responds
- to queries. Ntpd does the clock trimming.
-
- ntpdc - program to query an ntpd. It was useful in
- checking the filters and cleaning the windows
-
-Installation:
-
- 1) Add an entry to /etc/services to define the ntp port.
-
- ntp 123/udp # network time protocol (exp)
-
- 2) Make a /etc/ntp.conf with the clocks you want to track.
- Please refer to the RFC's in the man directory, the man
- pages, and the clock.txt file to assist you in selecting
- clocks to peer with. The supplied ntp.conf is only a
- sample, and is not suitable for use.
-
-
- 3) Change the Makefile definitions to suit your environment.
- 4) make
- 5) make install
- 6) adb or remake kernel and change "tickadj"
- Recommended values for tickadj on various machines:
-
- VAX: 5
- Sun3: 10
- Sun4: 5
- NeXT: 7
-
- This step is optional; new algorithms will allow you to
- get by (with reduced accuracy) with the system supplied
- value of tickadj. For better preformence, you should
- change the value of tickadj. This can be done by making
- a new kernel or by compiling ntpd with SETTICKADJ defined,
- and having ntpd set it to the value you specify. This is
- clearly ugly.
-
- 7) Fire up ntpd in /etc/rc.local
-
-History:
-5/17/89
- Yet another preprocessor define for broken unsigned long to double
- conversions. Define GENERIC_UNS_BUG, and the unsigned long is shifted
- right one bit and cast to an int before conversion to a double. This
- seems to work much better.
-
- Preliminary support for NeXT systems. Be sure to define both
- GENERIC_UNS_BUG and SUN_FLT_BUG. The default value of tickadj in the
- kernel is too large so you'll have to adjust it by using the
- -t option and compiling with SETTICKADJ. I don't think you can use
- gdb on the running /dev/mem image. NOTE: don't even think of trying
- to run this on the 0.8 release of the system software. You will
- utterly and absolutely hang you system. Current testing is being
- done on the 0.9 release. So far, there seems to be some weirdness in
- the kernel which is attempting to sync to the clock to the internal
- clock chip every so ofter. So while it compiles and runs, it really
- doesn't work very well on the NeXT machine.
-
- Integration of the reference clock code
- has been done. To configure a reference clock, check the
- ntpd manual page.
-
-5/3/89
- The changes to the ntp_proto.c module for clockhopper suppression have
- been tweaked once more, ever so slightly to conform with the 21 April
- 1989 draft of the NTP spec. We won't switch peers if the current
- peer makes it into the final selection list, unless the first peer on
- the selection list is of a higher stratum than the current peer.
-
- The ntpd.c/hourly() function now saves the value of the drift
- compensation register to a file (/etc/ntp.drift by default). In fact,
- the last 5 hourly samples are written to the file, as well as how
- many hours the ntpd process has been running. Ntpd will also attempt
- to intialize the value of the drift compensation register from this
- file when it is started up. The hourly stats: log message has been
- augmented to log additional information.
-
-4/8/89
- Changes to the ntp_proto.c module to supress peer switching when the
- dispersion between the newly selected peer and the currently selected
- peer is "small." A new configuration option, NOSWAP, has been added
- for use on Ultrix systems which can lock the ntpd process in memory;
- very desirable for diskless workstations. peer.reach is now not
- cleared in the clear() procedure. The stat.pl perl script can now
- handle syslog records which span a month boundary correctly. We're
- getting real close to a "blessed" version now.
-
-3/29/89
- A few fixes, clean up of unused #defines in ntp.h. The receive()
- procedure is now table driven per the 26 March 1989 draft of the
- spec. If no terrible errors or bugs are found, this version
- will probably be packaged as a "blessed" working version before
- the next stage of major hacking.
-
-3/22/89
- A bunch of minor fixes here an there. The RCS header is being
- updated so that patches that are generated will apply; apparently
- the new version of RCS puts the Locked: status in the Header
-
- Minor fiddles to ntpd/ntpdc to eliminate some byte-sex dependencies.
- Changs to ntp_proto.c to fix an mis-interpretation in the packet
- procedure.
-
- The ntp program now uses connected UDP sockets to pick up ICMP
- generated errors.
-
- ntpdc will now select a value of tickadj if you don't specify one.
-
-3/17/89
- Another sort-of-working ntpd. There might still be something weird
- with the logical clock code; seems to be a little weird. Would
- really like your comments on this version.
-
- Note that the a version that supports the Precision Time WWV clock
- can be had via anonymous FTP from BITSY.MIT.EDU. The version there
- might lag the University of Maryland version.
-
-3/12/89
- A snapshot of a more-or-less working ntpd. There's been a few more
- bug fixes and changes due to the NTP spec being revised. A few more
- changes have been made to the latest NTP spec (11 March 1989 version)
- which have not yet been applied.
-
- A few problems areas: I currently observe some peer flapping between
- two clock which are both of very good quality (UMD1.UMD.EDU and
- TRUECHIMER.CSO.UIUC.EDU). Not quite sure why this is happening yet
- or if it is really a problem.
-
- There are quite a few "Dropping peer <foo>" messages in the syslog.
- Most of these are due to lower statum "transient" clocks peering with
- the local daemon. Need to find a way to supress the messages in
- the transmit procedure when we've got no intention of keeping a
- peer structure around for them.
-
- There are changes in the works to improve the reliability of the
- ntpdc program. The ntpd hooks are there now, and some work remains
- in the ntpdc program.
-
-
-3/7/89
- *** THIS IS A TEST RELEASE ***
-
- This version contain most of the new algorithms from the 6 March 1989
- draft of the NTP specification. It still operates, however, as
- Version 1, and does not support the authentication feature.
-
- The stratum 1 WWV clock code from Doug Kingston has not been tested or
- changed for this release. I would really like someone to change the
- interface to have the clock appear as just another peer.
-
- Quite a bit if clean-up and cosmetic changes were made in almost all
- of the modules. Note that the ntest program which tests certain
- arithmetic operations on you machine is automatically run by the
- Makefile. If it fail *for any reason*, stop right there and find
- out why. Until ntest works correctly, don't even bother with the
- rest of the code. Note that at least Ultrix has problems, and there
- is a define option in the makefile to accomodate the broken Ultrix
- pcc compiler. Recent version of GNU CC are known to work correctly
- on a VAX platform, and is in fact used for development. It is not
- necessary to use the GNU C compiler on you machine, however.
-
- The logical clock code in ntp_adjust.c has been changed to be more
- self-contained and independent from NTP proper. It has the tickadj
- round-off residual accumulating code, and attempts to implemenet the
- newest version of the NTP logical clock code. A large change here is
- that once an clock update has been passed to the logical clock, it will
- ignore further updated for 1<<CLOCK_UPDATE seconds. Note that the
- units for tick_adj have changed in this version. Eventually, a
- normalized version of this value will be written to a file for use
- on subsequent invocations.
-
- There has been no work in the area of supporting broadcast NTP. A
- bunch of bug fixes have been made to the ntp_proto.c module, including
- a significant one in the code which selects the clock; the dispersion
- computed before was incorrect and resulted in poor clock choices. This
- is probably the cause of having long "strings" of peers rather then
- all syncing to one clock.
-
- The ntpd will now actually delete peer entries when the hosts "go
- away." This will hopefully save some memory. The peer list is now
- doublely linked, so deletions can happen very efficiently.
-
- There is still a weirdness in there when interoperating with very old
- broken versions of ntpd. It manifests itself with peers being expunged
- and them coming back.
-
- Please beat on this version and let me know what bugs you find. I
- want to make another release, this one "blessed" until the Version 2
- one is ready.
-
-
-1/12/89
- *** THIS IS A TEST RELEASE ***
- There have been a bunch of bug fixes, and an attemtp to unify the
- the debug output and logging. There is still a problem with the
- verbose version of ntpdc; the offset values are clearly bogus.
-
- Danger: don't attempt to run ntpd on a NeXT machine. It provokes
- a bug in the OS which hangs the machine quite absolutely.
-
- There is some support for a statrum 1 clock in some code provided by
- Doug Kingston (dpk@morgan.com). I'm not really sure that its the
- ``right'' way to do it; I'd rather have the clock appear just like
- another peer, and have it selected as a reference, just like you'd
- select any other clock. In fact, by doing it that way with some other
- support, you could even have a seperate process take care of reading
- the clock, and talking to the main process with some UNIX domain
- sockets... Hmm..
-
-12/8/88
- *** THIS IS A TEST RELEASE ***
- Really. We have tested this code on a VAX platform, but not much of
- anything else. I would like to hear back about any bugs, but you
- should not treat this as a 'release' version.
-
- Very large number of changes and updates. Files have been reorganized
- with ntpd.c containing intialization and other very UNIX specific code,
- while the new file ntp_proto.c contains the bulk of the NTP code.
- This version of the UNIX NTP daemon was re-written and updated to
- conform with the revised NTP specification.
-
- For all of the mucking about with tickadj, you can now define
- SETTICKADJ in the Makefile, and specify the value of tickadj in
- /etc/ntp.conf. The ntpd will attempt to update `tickadj' using
- /dev/kmem. Yow!
-
- If possible, ntpd will attempt to discover the value of your kernel's
- `hz' variable, and set the value of `precison' automagically. If
- `precision' is specified in /etc/ntp.conf, it will override any
- automatic selection.
-
- Only hosts which are configured or mentioned in /etc/ntp.conf on a
- `peer', `server' or `passive' statement are elligable to be
- synchronized to. This solves the "ganging-up" problem, but is sorta
- ugly.
-
- The `peer' statement in /etc/ntp.conf works just as before; it sends
- packets with MODE=SYMMETRIC-ACTIVE to the remote host. The remote host
- might synchronize to you if appropriate. If reachability is lost,
- polling will continue.
-
- The new `server' statement in /etc/ntp.conf causes packets of MODE=
- CLIENT to be sent to the specified host. The remote host will *not*
- synchronize to you under any circumstances. If reachability is lost,
- polling will continue.
-
- The new `passive' statement in /etc/ntp.conf causes packets of
- MODE=SYMMETRIC-PASSIVE to be sent to the remote host *when the local
- host is polled*. If reachability is lost, then polling will cease
- until the remote host begins to the local host again.
-
- Note conditional compilation define in the makefile for
- VAX_COMPILER_FLT_BUG for old 4.2 and Ultrix 2.0/2.2/3.0 pcc compilers.
- There is a bug in the code generated to convert an unsigned long to a
- double. Previously, this code was always present, but it is now
- #ifdef'd. The 4.3BSD-tahoe and GNU CC (1.30 and 1.31 at least) are
- known to work correctly. If you don't know if your compiler
- performs this conversion correctly, try making and running the
- `ntest' program, and see if test3 passes or not.
-
- The format of the data sent between ntpd and the ntpdc programs has
- changed yet again. It is likely to change again before the final
- release of this version.
-
-7/30/88
- Added and updated manual entries contributed by Glenn Trewitt.
- (trewitt@miasma.stanford.edu)
-7/27/88
- Reorder peer list so configuted hosts are always first. This
- REALLY helps the faleticker code.
-
- Changed ntpdc to have a larger RECV socket buffer. This fixes
- the "only see 20 peers" problem. This is a side affect of using
- UDP for the status return.
-
-6/20/88
- Support for hosts with multiple interfaces. Minor updates to
- the ntpdc program; note that the format of the messages between
- the ntpd and ntpdc programs is different in this version than the
- last. You should update both ntpd and ntpdc at the same time.
-
- New file ``ntp_sock.c''. Tested with Ultrix 2.4 field test, and
- 4.3 BSD tahoe release. Debug level can be adjusted by sending
- SIGUSR1 to increase and SIGUSR2 to zero the debug level.
-
-5/17/88
- Changed peer structure alloactor to stop allocating a perm
- structure for non-peer relationships. This make the ntpdc
- output a lot more understandable.
- Installed faletick code.
- Installed work around to bug in Ultrix C compiler.
- The compiler has troubles converting unsigned longs to floats.
- This caused a lot of off by 2 second problems.
-3/31/88
- The world is ALL different now. The NTP protocols have had
- some major structural work. This is the first rev that
- attempts to meet NTP version 1 compliance. There are a couple
- of loose ends (faltickers code and clock slew rate) that
- are not finished, but should be RSN. This release is to
- bridge the compatability with the old clock system.
-
- CHANGES:
- ntpsubs.c had a MAJOR bug in the tstamp routine. Accuracy
- should be much better now.
-
- The ntp.conf file is much simpler. List your precision
- and peers, the rest is automagic.
-
- The ntp/udp service mapping is now consitent. No more hard
- coded 123s.
-
- The math routines are more robust. They now handle signed
- conversion of longs and shorts.
-
- The control structure of ntpd is radically different. A peer
- relation is NOT setup for clocks at a higher stratum. This
- reduces table clutter, but you lose the history of those
- requesters.
-
-2/20/88
- Removed the median filter and replaced it with a minimum
- filter. Experimentation by Dave Mills suggests this is
- a better way to track network clocks. Changed status field based
- on updated RFC.
-
-12/29/87
- Only believe samples were the round trip delay is positive.
- I recommend HIGHLY that you change tickadj in /sys/conf/param.c
- to equal 1 instead of 40. This reduces the granularity of
- clock slewing from 4ms/sec to .1ms/sec. This should suffice
- if your clock is less that 4.3 minutes per month. If this is
- the case get a new clock, increase the value, or live with
- periodic clock jumps due to setimeofday(). The basic problem is
- that adjtime() slews only with "tickadj" granularity. That's
- argueably broken, but needs kernel mods to fix it.
-
-12/17/87
- Added some of the changes from Greg Fowler and Ken Stone
- of HP labs. This adds "hpux" compatability. Ken and Greg
- also tighten up the "bestclock" determination so you
- don't end up tracking yourself. (thanks again)
-
- The Precision field in now correct, precision is the power
- of 2 indication of internal clock tics. (ex. 60-HZ = -6)
- This is a constant for the machine and should be set in the
- ntp.conf file.
-
-12/1/87
- Massive cleanup in the daemon code. There was a BIG problem
- with "bestclock" peer calculation. A clock of a lower type would
- be tracked if the delay to that clock was lower than the delay
- to the higher precision clock. The peers listed in the ntp.conf
- files are marked as PERM. This causes a ntp gram to go to these
- guys regardless of any recv activity. This eliminates the problem
- of a peer being down and not talking ot him when he comes back
- up because the activity indicator went to zero. Using PERM
- entries creates a fixed overhead, use it with caution.
- There is the beginning of a second order filter that can be used
- to adjust the kernel tick rate. More on that when it's done.
- The data structures have changed for queries. Querying old
- clocks will cause problems. Note - the NTP protocol has NOT
- changed, only the query hack. The SET_THRESHOLD has been changed
- to be more reasonable with the max slew rate of 4.3BSD. This
- will be relaxed when the second order stuff is working.
-
-5/29/87
-
- All of the internal math is now done with doubles. This removes
-a lot of the hair and cost. On vaxen the double yields 54(5) bits of
-accuracy. The NTP timestamps are 64 bits. Converting to doubles
-will cause the loss of some bits on ost machines. This is not bad
-since most machines don't have clocks that could track even the lower
-16 bits of the NTP timestamps.
-
- NTP makes three choices on changing the local clock.
- 1) If the local clock apperars to be off by more than
- WAYTOOBIG (1000.0) seconds, it refuses to do anything
- but fill up you log.
- 2) If the local clock is off less than WAYTOOBIG but more
- than SET_THRESHOLD (2.0) a settimeofday will be done.
- 3) If the clock is off less than SET_THRESHOLD an adjustime
- is done.
-
- Ntpd clears out the samples after every clock adjustment.
- This helped to prevent the filter from overshouting based on old
- data.
-===========================================================================
-Still cooking on the stove are:
-
- modify adjtime - it won't allow small adjustments.
- I may punt and put in a new adjtime that handles
- the second order stuff.
-
- making it handle broadcasted time like timed

- * Routines defined:
- * init_clock_psti(): Open the tty associated with the clock and
- * set its tty mode bits. Returns fd on success

- * read_clock_psti(): Reads the clock and returns either 0 on success
- * or non-zero on error. On success, pointers are

-.TH RCP 1 "September 20, 1988"
-.UC 5
-.SH NAME
-rcp \- remote file copy
-.SH SYNOPSIS
-.B rcp
-[
-.B \-p
-] file1 file2
-.br
-.B rcp
-[
-.B \-p
-] [
-.B \-r
-] file ... directory
-.SH DESCRIPTION
-.I Rcp
-copies files between machines. Each
-.I file
-or
-.I directory
-argument is either a remote file name of the
-form ``rhost:path'', or a local file name (containing no `:' characters,
-or a `/' before any `:'s).
-.PP
-If the
-.B \-r
-option
-is specified and any of the source files are directories,
-.I rcp
-copies each subtree rooted at that name; in this case
-the destination must be a directory.
-.PP
-By default, the mode and owner of
-.I file2
-are preserved if it already existed; otherwise the mode of the source file
-modified by the
-.IR umask (2)
-on the destination host is used.
-The
-.B \-p
-option causes
-.I rcp
-to attempt to preserve (duplicate) in its copies the modification
-times and modes of the source files, ignoring the
-.IR umask .
-.PP
-If
-.I path
-is not a full path name, it is interpreted relative to
-your login directory on
-.IR rhost .
-A
-.I path
-on a remote host may be quoted (using \e, ", or \(aa)
-so that the metacharacters are interpreted remotely.
-.PP
-.I Rcp
-does not prompt for passwords; your current local user name
-must exist on
-.I rhost
-and allow remote command execution via
-.IR rsh (1).
-.PP
-.I Rcp
-handles third party copies, where neither source nor target files
-are on the current machine.
-Hostnames may also take the form ``rname@rhost'' to use
-.I rname
-rather than the current user name on the remote host.
-.SH SEE ALSO
-cp(1), ftp(1), rsh(1), rlogin(1)
-.SH BUGS
-Doesn't detect all cases where the target of a copy might
-be a file in cases where only a directory should be legal.
-.PP
-Is confused by any output generated by commands in a
-\&.login, \&.profile, or \&.cshrc file on the remote host.
-.PP
-The destination user and hostname may have to be specified as
-``rhost.rname'' when the destination machine is running the 4.2BSD
-version of \fIrcp\fP.

-.SH NAME
-rlogind \- remote login server
-.SH SYNOPSIS
-.B /etc/rlogind
-[
-.B \-ln
-]
-.SH DESCRIPTION
-.I Rlogind
-is the server for the
-.IR rlogin (1)
-program. The server provides a remote login facility
-with authentication based on privileged port numbers from trusted hosts.
-.PP
-.I Rlogind
-listens for service requests at the port indicated in
-the ``login'' service specification; see
-.IR services (5).
-When a service request is received the following protocol
-is initiated:
-.IP 1)
-The server checks the client's source port.
-If the port is not in the range 512-1023, the server
-aborts the connection.
-.IP 2)
-The server checks the client's source address
-and requests the corresponding host name (see
-.IR gethostbyaddr (3),
-.IR hosts (5)
-and
-.IR named (8)).
-If the hostname cannot be determined,
-the dot-notation representation of the host address is used.
-.PP
-Once the source port and address have been checked,
-.I rlogind
-proceeds with the authentication process described in
-.IR rshd (8C).
-It then allocates a pseudo terminal (see
-.IR pty (4)),
-and manipulates file descriptors so that the slave
-half of the pseudo terminal becomes the
-.B stdin ,
-.B stdout ,
-and
-.B stderr
-for a login process.
-The login process is an instance of the
-.IR login (1)
-program, invoked with the
-.B \-f
-option if authentication has succeeded.
-If automatic authentication fails, the user is
-prompted to log in as if on a standard terminal line. The
-.I -l
-option prevents any authentication based on the user's
-``.rhosts'' file, unless the user is logging in as the superuser.
-.PP
-The parent of the login process manipulates the master side of
-the pseudo terminal, operating as an intermediary
-between the login process and the client instance of the
-.I rlogin
-program. In normal operation, the packet protocol described
-in
-.IR pty (4)
-is invoked to provide ^S/^Q type facilities and propagate
-interrupt signals to the remote programs. The login process
-propagates the client terminal's baud rate and terminal type,
-as found in the environment variable, ``TERM''; see
-.IR environ (7).
-The screen or window size of the terminal is requested from the client,
-and window size changes from the client are propagated to the pseudo terminal.
-.PP
-Transport-level keepalive messages are enabled unless the
-.B \-n
-option is present.
-The use of keepalive messages allows sessions to be timed out
-if the client crashes or becomes unreachable.
-.SH DIAGNOSTICS
-All diagnostic messages are returned on the connection
-associated with the
-.BR stderr ,
-after which any network connections are closed.
-An error is indicated by a leading byte with a value of 1.
-.PP
-.B ``Try again.''
-.br
-A
-.I fork
-by the server failed.
-.PP
-.B ``/bin/sh: ...''
-.br
-The user's login shell could not be started.
-.SH "SEE ALSO"
-ruserok(3), rshd(8)
-.SH BUGS
-The authentication procedure used here assumes the integrity
-of each client machine and the connecting medium. This is
-insecure, but is useful in an ``open'' environment.
-.PP
-A facility to allow all data exchanges to be encrypted should be
-present.
-.PP
-A more extensible protocol should be used.

-** /dev/ptym/pty[p-z][0-9][0-9]

- * Modified by Glen A. Foster, September 23, 1986 to get around a problem
- * with 4.2BSD job control in the HP-UX (a.k.a. system V) kernel. Before
- * this fix, getpty() used to find a master pty to use, then open the cor-
- * responding slave side, just to see if it was there (kind of a sanity
- * check), then close the slave side, fork(), and let the child re-open
- * the slave side in order to get the proper controlling terminal. This
- * was an excellent solution EXCEPT for the case when another process was
- * already associated with the same slave side before we (telnetd) were
- * exec()ed. In that case, the controlling tty stuff gets all messed up,
- * and the solution is to NOT open the slave side in the parent (before the
- * fork()), but to let the child be the first to open it after its setpgrp()
- * call. This works in all cases. This stuff is black magic, really!
- *
- * This is necessary due to HP's implementation of 4.2BSD job control.

-/*
- * Modified by Byron Deadwiler, March 9, 1992 to add access to the clone
- * driver to get ptys faster. Also added code to access ptys using
- * a new namespace (naming convention) that increases the number of
- * pty's that can be configured on a system.
- *
- * Name-Space It is a union of three name-spaces, the earlier two
- * being supported for compatibility. The name comprises
- * a generic name (/dev/pty/tty) followed by an alphabet
- * followed by one to three numerals. The alphabet is one
- * of the 25 in alpha[], which has 'p' thro' 'o' excluding
- * 'd'. The numeral is either hex or decimal.

-.TH RSH 1 "September 20, 1988"
-.UC 5
-.SH NAME
-rsh \- remote shell
-.SH SYNOPSIS
-.B rsh
-host
-[
-.B \-l
-username
-] [
-.B \-n
-] command
-.br
-host
-[
-.B \-l
-username
-] [
-.B \-n
-] command
-.SH DESCRIPTION
-.I Rsh
-connects to the specified
-.I host,
-and executes the specified \fIcommand\fR.
-.I Rsh
-copies its standard input to the remote command, the standard
-output of the remote command to its standard output, and the
-standard error of the remote command to its standard error.
-Interrupt, quit and terminate signals are propagated to the remote
-command; \fIrsh\fP normally terminates when the remote command does.
-.PP
-The remote username used is the same as your local username,
-unless you specify a different remote name with the
-.B \-l
-option.
-This remote name must be equivalent (in the sense of
-.IR rlogin (1C))
-to the originating account; no provision
-is made for specifying a password with a command.
-.PP
-If you omit
-.I command,
-then instead of executing a single command, you will be logged in
-on the remote host using
-.IR rlogin (1C).
-.PP
-Shell metacharacters which are not quoted are interpreted
-on local machine, while quoted metacharacters are interpreted on
-the remote machine.
-Thus the command
-.PP
-\ \ \ rsh otherhost cat remotefile >> localfile
-.PP
-appends the remote file
-.I remotefile
-to the localfile
-.I localfile,
-while
-.PP
-\ \ \ rsh otherhost cat remotefile ">>" otherremotefile
-.PP
-appends
-.I remotefile
-to
-.I otherremotefile.
-.PP
-Host names are given in the file /etc/hosts. Each host
-has one standard name (the first name given in the file), which
-is rather long and unambiguous, and optionally one or more nicknames.
-The host names for local machines are also commands in the directory
-/usr/hosts; if you put this directory in your search path
-then the
-.B rsh
-can be omitted.
-.SH FILES
-.ta 2i
-/etc/hosts
-.br
-/usr/hosts/*
-.DT
-.SH SEE ALSO
-rlogin(1)
-.SH BUGS
-If you are using
-.IR csh (1)
-and put a
-.IR rsh (1)
-in the background without redirecting its input
-away from the terminal, it will block even if no reads
-are posted by the remote command. If no input is desired
-you should redirect the input of
-.I rsh
-to /dev/null using the
-.B \-n
-option.
-.PP
-You cannot run an interactive command
-(like
-.IR rogue (6)
-or
-.IR vi (1));
-use
-.IR rlogin (1).
-.PP
-Stop signals stop the local \fIrsh\fP process only; this is arguably
-wrong, but currently hard to fix for reasons too complicated to
-explain here.
