LJDT: Reliable Service / Connection Tests; netcat, not ping, is the correct tool

This entry is part 8 of 10 in the series LJDT - Linux Just Does That

Me: “I cannot get to your site.” Helpdesk: “Hmm, let me check. I can ping it, so it must be okay.” Me: “No, pinging has nothing to do with access to the site.” Helpdesk: “No, you’re crazy, I can ping it so it’s your problem. Goodbye.” If you have never had this type of exchange with others, you’re lucky. The fact of the matter is that ‘ping’, while a good (but not 100% even here) tool to determine if traffic can go from one IP to another, is a lousy tool for determining if anything more than layer three is working …

Apache2 could not bind to address 0.0.0.0:631 after vSphere upgrade

After the upgrade from vSphere 4.0x to vSphere 4.1 or ESXi 4 to ESXi4.1 apache on a OES 2 server wouldn’t start with the error: apache2 could not bind to address 0.0.0.0:631 after vSphere upgrade

As you all probably know TCP port 631 is for IPP print, or for us Novell guy’s iPrint. iPrint is started with apache (the website that is). But if iPrint cannot start, apache wouldn’t start also. So what’s blocking TCP port 631?
