how to open http access
 

How can i open http access remotely via SSh ? on CentOS 5.3

(i can not access to my webpage using web browser (port 80))

This is not CentOS specific, but here is an excellent tutorial on setting up ssh in linux. I have found this very helpful for setting up ssh in several distros:

And an article on security practices when using ssh:

Hope this helps.

Here's the RHEL Deployment guide http://www.linuxtopia.org/online_boo...ion/index.html, works just as well for Centos.
