Public bug reported:
Ubuntu 13.04
cups: 1.6.2-1ubuntu5
I'm trying to connect to a remove cups server as a client. In
/etc/cups/client.conf I have set
ServerName myserver.foo:631 (also tried without :631)
cups-browsed then runs at 100% CPU. It has been killed using the -9
option. Printing to the remote server does not work (it used to work in
precise).
I've straced the process and it goes into an infinte loop here (IP
address of server replaced with 111.111.111.111):
fcntl(7, F_SETFD, FD_CLOEXEC) = 0

I tried editing cups-browsed.conf. I changed the protocol to cups from
dnssd, which gave the same problem. Changing to n one stopped the hang,
but then I couldn't access the remote server.
