lxadmin aka Kloxo not listening in a centos after a default installation. Please help!

Klaxo was installed without any errors. But still inside the server Klaxo and the stuffs were working, but from a browser in the WWW, it isn’t and hows cannot be found or page cannot be displayed errors

telnet ip.ip.ip.ip 7777 was working from inside the server, but not from outside network. It was showing,

telnet ip.ip.ip.ip 7777
Trying ip.ip.ip.ip...
telnet: Unable to connect to remote host: No route to host

It was returning the same for every port, except 22. In a normal situation, if the port 22 also was not working, the issue could have been network related, but in this case port 22 was working fine. So the issue was not related to networking, but …… ? Guess what ?

Yes. Any seasoned administrator should have guessed the answer to be the firewall and yes that was right. The iptables ruleset had a line which says,

REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited

Deleted that line and things went smooth after that.

Don’t forget to run save the iptables rules, by executing the commands below,

[root@server ~]# iptables -D RH-Firewall-1-INPUT 10
[root@server ~]# /etc/init.d/iptables save
Saving firewall rules to /etc/sysconfig/iptables: [ OK ]
[root@server ~]# iptables-save
