I was wondering if you guys could help me trouble shoot why I am not able to view my IPs in a website browser. I have activated them, added a file, etc. Linode suggested that I don't have a web server running on my IPs, but I thought I had Apache running. I'm confused (also new, so bear with me). Thanks so much.

You've added IPs to your linode? Have you rebooted? You need to reboot after adding new IPs.

Yes, I added IPs to my linode, then rebooted. I see them all in PuTTY and have activated them through there as well as added directories, etc. Now, I was trying to test them by going to the IP in Firefox, but it says that it can't establish a connection to the server.

Did you set up apache's config files?

Do you have a firewall running? If so have you opened port 80 on the new ips?

I set up a configuration file within Apache to listen to the IPs on port 80 and 443?

The configuration file is called ports.conf... I'm doing some other research that suggests that httpd.conf is the place where this stuff should be. Should I transfer the information to that file?

Ah...I figured it out. Thank you guys so much for your help. I really appreciate it!

debuntu don't use httpd.conf, they use a bunch of other small files to do it, as it looks like you found.
