Nah, if you can telnet to port 9100 you should be good. I didn't expect you
to get anything back from port 9100, but you should be able to establish a
connection (as opposed to timeout of connection refused).
You can't ping since your filtering out ICMP so that's normal. I suppose it's
possible that cups is attempting to check if the printer is present using a
ping, but I don't think it does that.
BTW, I haven't followed your whole story, did you try reinstalling cups? You
can't remove it because of the dependencies, but you can get around this with
the --nodeps option, and since your going to immediately reinstall it this
won't be a major issue.
The other option would be to simply force a reinstall with rpm -Uvh --force
which is nearly as effective as removing and reinstalling in most cases (say
if a backend has been inadvertently deleted or some previous update went awry).
Assuming those don't work, please outline the exact steps that you are using
and exactly when you get the error.
Later,
Tom
