Hi folks,
I have two hosts on a network. Both have
Browsing On
BrowseOrder allow,deny
BrowseAllow from @LOCAL
BrowseAllow from @IF(eth0)
BrowseAddress @LOCAL
in cupsd.conf (I added Browsing On here in addition to browse.conf in
case there was an issue with the include order).
Both are also listening on the local network:
ports.conf:
Listen /var/run/cups/cups.sock
Listen localhost:631
Listen hardknott.home.whinlatter.ukfsn.org:631
The other machine is the same, but with a different hostname.
I don't see any remote printers on either system. Both are listening
on UDP and TCP:
rleigh@liet:~$ netstat --tcp --udp -l | grep ipp
tcp 0 0 liet.home.whinlatte:ipp *:* LISTEN
tcp 0 0 localhost.localdoma:ipp *:* LISTEN
udp 0 0 *:ipp *:*
rleigh@hardknott:/etc/cups$ netstat --tcp --udp -l | grep ipp
tcp 0 0 hardknott.home.whin:ipp *:* LISTEN
tcp 0 0 localhost:ipp *:* LISTEN
udp 0 0 *:ipp *:*
I can't see any reason why there are no broadcasts, or no broadcasts
are recieved.
(When I first set up the second server, it saw all the first server's
printers, and briefly the first server saw the second server's
printer, but now there's nothing. It was presumably some tiny
configuration tweak that caused this, but everything is, AFAICT,
enabled and set up correctly.)
Regards,
Roger
