[cdesktopenv-devel] Iptables and CDE

[uid s <ui...@gm...>]

I read somewhere that using CDE with some iptables rules would not be
functioning properly.

I'm runing a basic ruleset allowing only incoming ssh connections only.

This is the "quick copy and paste" if someone finds utility.  It could be
done better , for sure. ( The loopback OUTPUT rule is recursive ;)  ) ,
Change the DROP/REJECT policy as you want.

iptables -F
iptables -Z
iptables -X

iptables --policy INPUT DROP
iptables --policy FORWARD DROP
iptables --policy OUTPUT ACCEPT
iptables -A INPUT -i lo -j ACCEPT
iptables -A OUTPUT -o lo -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables --append INPUT --match state --state ESTABLISHED,RELATED --jump
ACCEPT
iptables --append INPUT --jump REJECT
iptables --append FORWARD --jump REJECT
