hey friends, I have configured CVS on FC3.Now the problem is that if the iptables is on then I am not able to access the cvs from the windows clients but if the iptables is off then I can access it. I have given these entries in Iptables iptables -A INPUT -p tcp -i eth0 -s 192.168.1.0/24 --dport 2401 -j ACCEPT iptables -A INPUT -p tcp -i eth0 -s 192.168.1.0/24 --dport 2402 -j ACCEPT after giving these entries I am still not able to access the CVS.SELinux is on but when I give iptables -F I am able to access the cvs server so the problem lies with Iptables. Even i gave these entries also iptables -A INPUT -p udp -i eth0 -s 192.168.1.0/24 --dport 2401 -j ACCEPT iptables -A INPUT -p udp -i eth0 -s 192.168.1.0/24 --dport 2402 -j ACCEPT and iptables -A INPUT -p udp -s 192.168.1.0/24 --dport 2401 -j ACCEPT iptables -A INPUT -p udp -s 192.168.1.0/24 --dport 2402 -j ACCEPT iptables -A INPUT -p tcp -s 192.168.1.0/24 --dport 2401 -j ACCEPT iptables -A INPUT -p tcp -s 192.168.1.0/24 --dport 2402 -j ACCEPT But still I am not able to access the cvs server from windows client(Tortoise CVS on Windows XP Pro SP2).
