i have setup iptables with following rules
Code:
#!/bin/sh

$IPTABLES -A INPUT -i eth1 -p tcp -s $INT_NET --dport 4444 -j ACCEPT
$IPTABLES -A INPUT -p icmp --icmp-type echo-request -j ACCEPT

then i said on shell:
[CODE]
>service iptables save
>chkconfig iptables on
[CODE]
upon restarting my system i found service "rpc.statd" failing
also gnome takes a lot of time to start
and shows the following error
Quote:
There was an error starting the GNOME Settings Daemon.
Some things, such as themes, sounds, or background settings may not work correctly.
The last error message was:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
GNOME will still try to restart the Settings Daemon next time you log in.
