 |
|
I'm struggling to understand CUPS' configuration directives. Specifically: Browsing. What is browsing, anyway?! 
e.g., I'm using CUPS on my Mandrake-workstation (172.16.1.99) and on my Gentoo gateway/print-server (172.16.1.1). When I check the web-interface of my workstation (http://172.16.1.99:631) I don't see the printer that is attached to my gateway, but once I manually configure my workstation to use the gateway's attached printer (http://172.16.1.1:631/printers/LaserJet) I can see the workstation's printer (LaserJet@172.16.1.99) when using the gateway's web-interface to view it's printers (http://172.16.1.1:631/printers)! (i.e., There's some sort of weird circular-relationship going on between the two CUPS servers.) 
Workstation:
| Code: | BrowseAddress @LOCAL
BrowseDeny All
BrowseAllow 127.0.0.1
BrowseAllow @LOCAL
BrowseOrder deny,allow
BrowsePoll @LOCAL |
Gateway:
| Code: | BrowseAddress @IF(eth1)
BrowseAddress @IF(eth2)
BrowseAllow @IF(eth1)
BrowseAllow @IF(eth2)
BrowseDeny @IF(eth0)
BrowseOrder deny,allow |
How can I configure...
1. the gateway to announce the availability of the printer that is attached to it? (i.e., to share http://172.16.1.1:631/printers/LaserJet)
2. the workstation to listen for printers available on the LAN?

So it appears that the key to making the server's printers visible to my workstation is the BrowserPoll setting. (Configuring the ServerName setting - in /etc/cups/client.conf - did not have the desired effect.)
Workstation: | Code: | BrowseAddress @LOCAL
BrowseDeny All
BrowseAllow 127.0.0.1
BrowseAllow @LOCAL
BrowseOrder deny,allow
BrowsePoll 172.16.1.1

ROTFL!!! Yes - that was a tremendous help for my overwhelming sense of bewilderment! 
I've been feeling like such an idiot because every article that I read heralds CUPS' easy-to-use interface (without, of course, addressing it's configuration).
Thanks, snakeroot!
