TCP/IP problems, RH 8 can't print
|
|
|
| Hi.
I screwed up my TCP/IP when trying to put this machine behind a
Smoothwall Express firewall. I've since put that project on hold and am
trying to simply get my RH pc working again.
The printer won't print and OpenOffice crashes if I try to save. I
think both are related to the error message I got from Gnome at startx
"Gnome might not work correctly. Try putting localhosts.localdomain in
/etc/hosts.
Well, I put that back in manually, but it didn't solve anything. I have
tried using the RH network gui tools to get this working again and they
have put the following into my /etc/hosts file.
# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.0.101 localhost.localdomain drPC
192.168.0.2 is the IP address of my wired/wireless router. It provides
DHCP through an ethernet NIC to this PC and via wireless to a second.
So why won't lpd work? I can't print from Emacs, or even run the test
page from RH's printer tool. Why does OpenOffice crash? And as
importantly, what do I do to fix this mess I've made?
Thanks!

Change it to:
127.0.0.1 localhost.localdomain localhost
192.168.0.101 drPC

| Wow, Scott. That worked. Wish I knew why! But I just bought a book on
TCP IP and hopefully I'll be answering my own question. Thanks so much!

It's not really an ip issue. The short answer is that many services and
programs rely on the name 'localhost' resolving to 127.0.0.1.
Funny work story. One of the techs had modified all of the host files
on the HPs and dropped the localhost line. Everything worked fine until
the DNS server died because the DNS server would always resolve localhost
to 127.0.0.1. Took him a day to figure it out.
