Firewalls and Security

Firewalls:
Open the ports for all of the servers we are going to be doing this quarter. Do not open a port for telnet as this is dangerous for a server and can be used to easily hack a server. Open SSH, FTP, DNS, Apache will also be considered port 80 HTTP/HTTPS, NFS, NIS, SMTP, IMAP, POP3, CUPS, and Samba.

NSA Secure Linux: SELinux
Trouble Shoot SE Linux for each server that you setup. Your SELinux should be set to permissive mode.
