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/)?
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?
I‘ve setup FreeBSD and OpenBSD under KVM. Everything works great except ftp protocol. I’ve no firewall installed inside FreeBSD and OpenBSD. How do I configure Linux host KVM firewall to allow ftp traffic?
