mjl 8515b446a0 Fix null terminating the wrong buffer curtesy of similar variables
mixed up. Seemed to never have any ill effect, but then...

mrg 2a987cd998 - use symbolic names for mode bits
- use _exit() where we should
- fix spelling mistake
- use vasprintf() in pstatus()
all from freebsd.

mrg 2e2dfe5c71 tsk. tsk. document new features i added. 1999-12-10 23:49:03 +00:00
mrg 5b6d0e7e39 - add timeouts to displayq(), rmremote(), sendfile() and response(),
and use these timeout in the lpq, lpd and lprm programs.

these stop hung remote printers that accept tcp connections but do
not process jobs from hanging the whole system and letting the sysadmin
have a clue about what is going on with this rogue printer.

- add a -r flag to lpd to allow `of' filters for remote jobs.

i know there are ways around this, but i just don't care.

- add a -f flag to lpf to add missing carriage returns.

useful when printing UNIX files to an, eg, LaserWriter that wants CR's
as well as LF's in raw text.  stair-stepped text is no fun.

- implement child process accounting: we just have a limit on the number
  of children we can have (settable by the sysadmin), and we sleep when
  this number is reached.  this can reduce malicious not-so-malicious
  attacks on the print server by a rogue remote client..

- use setproctitle() where appropriate so the sysadmin has a clue about
  what each of the lpd's here are doing.

this was useful to help diagnose a problem (that the above child process
accounting change reduces the lossages of) where a rogue client was
attempting "lpq" operations on one stuck queue in rapid succession,
causing the lpd server to be extremely slow, due to the large number
of lpd processes running.


i have been running these changes in production for about a year.

mrg 23b9fac082 delint and other cleanups. 1999-09-26 10:32:27 +00:00
garbled d1407362ba More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages.  Many more to
come.

perry d8e1329af8 close out pr 2771, which added a -s ("secure") flag to lpd -- makes
lpd run in a mode where the it listens only to the local unix domain
socket and not to the network. Changes are similar but not identical
to the supplied patches.

jtc d7eb41bd8e Changed to not use a compiled in table of baud rates. Evidently
there are some PC/Mac oriented devices that use non-standard speeds,
furthermore that's just not the way we do things anymore.

"Bad" baud rates are no longer caught with their own error message,
but the condition will still be diagnosed when the tcsetattr() fails.

pk fee478451f `/dev/printer' => `/var/run/printer' (PR#2552).
Also, change `.Os 4.2' => `.Os 4.4' (this man page is from 4.4 lite), and
for now, refer to the "BSD 4.3 Line printer manual", because that is what
we now have in lpr/SMM.doc (SMM.doc needs updating too).
