Description of problem:
When sharing is enabled for a locally connected printer, ipp:udp is
opened in iptables, but ipp:tcp is not. The effect is that the
printer is viewable from client machines, but jobs queue on the client
Opening ipp:tcp on the server in system-config-securitylevel causes
the client's queue to flush and all jobs to print. Also allows
client's eggcups to view job status, which it won't do without the TCP
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use system-config-printer to enable sharing.
2. Check firewall status with "service iptables status".
3. Print a job to the shared printer from another machine via IPP.
Actual Results: In step 2, ipp:udp is open, but ipp:tcp is not.
In step 3, job hangs in queue. Client's eggcups shows unknown name
Expected Results: In step 2, probably ipp:tcp should be open as well.
In step 3, job should print and eggcups should show proper name and size.
system-config-printer doesn't open any ports at all, because there is no
infrastructure to do so. (I've been saying this for *ages*.)
Yeah we should sort for FC4.
