Our customer support wiki runs on an internal host (ip:192.168.1.100:300, hostname a-node100.:300) and it is behind the nginx reverse proxy server. However, our Apache server end up displaying internal server name http://a-node100.:300/, which results into an unexpected redirection and timeouts as http://a-node100.:300/ is not accessible over the Internet. How do I force nginx or apache to use the base URL of our server (http://support.example.com/wiki/)?

I’ve setup Squid Proxy server as described here, but I’m getting errors which read as follows:

Jul 14 15:09:02 server1 squid[5315]: Squid Parent: child process 5317 started
Jul 14 15:09:02 server1 squid[5317]: Cannot open HTTP Port
Jul 14 15:09:02 server1 squid[5315]: Squid Parent: child process 5317 exited due to signal 6
Jul 14 15:09:02 server1 setroubleshoot: SELinux is preventing the squid (squid_t) from binding to port 5000. For complete SELinux messages. run sealert -l 1cf3c788-35f7-4752-8439-92a1d0719466

How do I fix this problem?

NFS was not designed with security in mind, and has a number of weaknesses, both in terms of the protocol itself and because any NFS installation must expose several daemons, running on both servers and clients, to network attack. I use my CentOS based server only to server web pages and nothing else. How do I disable NFS services under RHEL / CentOS / Fedora Linux?
