Folks, I am trying to figure out the filewall script that SuSE provides to get the firewall going. There is one line: if test -f /proc/net/ip_fwchains -a `cat /proc/sys/net/ipv4/ip_forward` -eq 1 ; then ... fi Can someone enlighten me as to what is going on here. I know that they are testing for equality to 1, but /proc/net/ip_fwchains is not a script or a program, what is the part: /proc/net/ip_fwchains -a `cat /proc/sys/net/ipv4/ip_forward` For that matter what is the /proc/net/ip_fwchains and what is the /proc/sys/net/ipv4/ip_forward?
