Subject: [SOLVED] (almost...) lpd and remote users failure
Please, can you post the following to the list? My newsserver is
out-of-work :(.
**begin "article" :) ****
Resume: lpd refuse (silently(1)) to serve print request from remote
hosts, although the flag :rs: (see man 5 printcap) is *NOT* present
in the /etc/printcap file.
*Warning*: the proposed solution is a hack, a horrible hack, a
solution that cure only the symptom, not the real problem. But it
works for me and I _need_ a working lpd server. Can anyone send this
to the right redhat mail address?
Sorry no rpm package, I do not know how to build it correctly. I
solved the problem applying the patch included in this messages
(way to go: install with rpm -ivh lpr-0.21-2.src.rpm;
go to /usr/src/redhat/SPECS, do rpm -bp lpr.spec,
cd /usr/src/redhat/BUILD, apply with patch -p0 <this_file,
cd lpr, make all. Now substitute your lpd with the binary in
the lpd subdirectory (2)).
How this solution works: if the remote users does not exist in the
system were lpd is running, the username is substituted with
"lpdguest". then all is like before. So, you create a "lpdguest" user,
the printing is honored, otherwise it is silently(1) ignored like
before. A warning is issued in the syslog.
(1) This is, in my opinion, a bug. At least when running with -l,
lpd should say something when dropping a print request.
(2) If you trust me, and if my PC is online (just try), you can
download the binary from ftp://sirio.iet.unipi.it/pub/romano/lpd. Just
get it and chmod +x it in /usr/sbin.
