sendmail hangs, seemed to have lost external email and can't browse internet now!
I run redhat enterprise Linux ES release 4 (Kernal 2.6.9-42.ELsmp on an i686).
must have done something? its just that I am such a pathetic novice that I don't even know where to look??? Please help. Sendmail, browing from netscape (via redhat gui screen). I recently changed the hostname on my machine ( I changed it from "cubit" to "bullwork"). Then the problem goes... I probably changed a few things - you know, novice tinkering away... It was working initially, but tonight I did a reboot and noticed sendmail hanging for a few extra minutes on reboot. Then I noticed a httpd error: Jan 5 21:47:07 bullwork httpd: httpd: Could not determine the server's fully qu alified domain name, using 192.168.3.15 for ServerName Also noticed that I can't send and receive emails to the world anymore. Also, logged in via the Xwindow and noticed that I can no longer browse the internet from there anymore. Strangely though, I can still bring up the hosted website on that machine from a pc (so the machine is connected to the internet at least for incoming traffic???) Here is my /etc/hosts: # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 192.168.3.15 bullwork here is /etc/sysconfig/network: NETWORKING=yes HOSTNAME=bullwork here is /etc/resolve.conf: ; generated by /sbin/dhclient-script search lan nameserver 192.168.3.1 What have I done? What can I try (before I pull all of my hair out!!) I'd appreciate the help very much, thanks Greg. much? |
sorry... Firefox is the browser.
just noticed though.. I can browse using the ip address of the sites: eg: http://74.125.19.99 gets me to www.google.com.au, but www.google.com.au aint working. not sure if this is related to my sendmail hanging problem... or connected to my not getting/sending external emails? Greg. |
That usually indicates your DNS is not working.
Have a look at (contents of) /etc/resolv.conf does it have the 2 DNS servers of your ISP listed? |
