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
Thanks again. Being naturally chicken, I tried the reinstall procedure
first (no luck) and then the --force remove and normal install. Everything
went all right on the reinstall, but the printer is still not recognized.
It still comes back with the same error.
I'm still running RHEL 3 update 5. Maybe the problem will resolve itself in
RHEL 4, but that upgrade is REALLY scary.
Regards,
Rick Danielson
