Hi all,

I've been trying to add a second ip address to one of my network cards in my CentOS box. I've defined the alias on top of eth1 which has become eth1:1 with a different ip address.

I can ping the new ip address both from my linux box as well as from my Windoze desktop, however I can only access my Apache web server setup as a virtual host from within the Linux box. If I try to access it from the desktop I get an "Operation Timeout..." error.

I'm sure I missed out something really basic. Browsed Google and the CentOS mailing list (plus RH) and can't figure it out. Networking is not one of my best subjects... Someone care to shed some light or point me to a fairly decent link out there which covers this topic?

Have you restarted apache? Does your httpd.conf have a Listen * directive or does it only listen on explicit ip addresses? If you do a netstat -at, does it show apache listening on that the interface?

It could also be something in your iptables. E.g. using -i eth1 for your http rule. If so, you can use the more flexible -i eth+ (or eth1+).

Also, you can codify your alias, using /etc/sysconfig/network-scripts/ifcfg-eth1:1
