Hello,
I am new to Linux.,I just installed Centos 6.2 64 bit on a dell xps 420. I picked virtual server and a couple of desktop packages during the installation and everything seems to work fine, however when I login as root to ssh and try to execute the /etc/sysconfig/system-config-firewall I get permission denied. Also if I try to access through the gui (under system, then administration) there is simply no firewall option there. Is there a package I forgot to install? What am I doing wrong?
System-config-firewall permission denied
System-config-firewall permission denied
The file you are trying to execute is just where it keeps the configuration related to the firewall, it isn't designed to be executed. You need to run system-config-firewall-tui (text mode) or system-config-firewall (GUI) and install those packages if they're not found.
