NAME¶
rlprm - remove jobs from a remote line printer spooling queue
SYNOPSIS¶
rlprm [-qNV] [
-Hprinthost] [
-Pprinter] [
-Xproxyhost]
[
--debug] [
--timeout=seconds] [
--port=port] [-] [
job
# ... ] [
username ... ]
DESCRIPTION¶
rlprm uses TCP/IP to remove jobs you own from printers anywhere on a
network. Unlike lprm, it does not require that the remote printers be
explicitly known to the local system (traditionally through
/etc/printcap), and thus is considerably more flexible and requires
less administration.
rlprm can be used anywhere a traditional
lprm might be used, and
is backwards compatible with traditional BSD
lprm. If
rlprm is
invoked as
lprm, it preserves all known lprm semantics, with the
exceptions of those semantics mentioned in
BUGS / LIMITATIONS below.
rlprm can be set up, installed, and used in the same two ways as
rlpr(1) (that is, either with or without the
rlprd(8) proxy
daemon). Please see
rlpr(1) for details, and to see whether you will
need to use the
rlprd(8) proxy daemon or not.
OPTIONS¶
Environment/Setup¶
- --debug
- Print gobs of debugging information.
- -N, --no-bind
- Don't try to bind to privileged port before connecting to lpd. Please see
the CONFIGURING A PROXY section in rlpr(1) for information
on use of this option.
- --port=number
- Select an alternate port (instead of 7290) to connect to, if using rlprd.
Usually not needed.
- -H, --printhost=host
- Select the host to print to (used with -P).
Instead of using -H, one can specify the hostname directly including
it with the printer name with the printer@hostname syntax.
- -P, --printer=printername, --queue=printername
- Select the printer to print to (used with -H).
- -X, --proxy=proxyhost, --proxyhost=proxyhost
- Select the proxy host to use, if necessary.
- --timeout=seconds
- Set the inactivity timer. If the connection hangs for more than
seconds seconds, then rlprm will give up. Use the special
value `-1' to wait forever. Default timeout is 3 seconds.
- -V, --version
- Print version and exit.
Behavior¶
- -
- Remove all of your jobs. Note that this option must be specified
immediately following the end of all other options. This option is a
mutant supported only for compatibility. Instead of using this, include
your username as the first argument to rlprm.
- -q, --quiet, --silent
- Quiet mode - stay quiet (except for fatal errors). See BUGS /
LIMITATIONS for problems using rlprm in silent-mode
operation.
ENVIRONMENT VARIABLES¶
The following environment variables are used by
rlprm:
- RLPR_PRINTHOST
- Specifies the default host's queue to remove jobs from.
- PRINTER or LPDEST
- Specifies the default printer to remove jobs from on the host.
First PRINTER is consulted, then LPDEST.
Note that one can also specify the host to examine by setting printer to be
printer@hostname. This may be more convenient than setting
RLPR_PRINTHOST, but will confuse the traditional BSD print
commands.
- RLPR_PROXYHOST
- Specifies a proxy host to use, if necessary.

BUGS / LIMITATIONS¶
Due to limitations in the current lpd protocol, it is not currently possible to
tell whether or not the job removal succeeded when operating in silent mode.
Due to limitations in the current lpd protocol, it is not currently possible to
emulate the superuser semantics for the `-' option. Instead, only root's jobs
are removed.
Due to general niavete in the lpd protocol,
rlprm(1) provides a lot of
room for misbehavior; it is trivial to imagine how it can be used to remove
jobs that do not belong to you. Unfortunately, any security added at this
point is just sugar-coating -- the underlying protocol is flawed.
