UNIX for Dummies Questions & Answers

Hello

I'm using Centos 5.10 with latest CSF installed. Yesterday I did some changes from UI. I only changed SU/SSH login alerts set to root and it was working great for like 6 hours. Today when I saw my mail box I got around 50 mails with this

Code:

lfd failed @ Wed Mar 26 06:55:41 2014. A restart was attempted automagically.

Then I quickly checked few things, but I was getting these errors :

Code:

centos *Error* LF_DAEMON not enabled in /etc/csf/csf.conf, at line 70

Error: (iptables binary location) does not exist!, at line 41

So I had to contact my host and they said iptables crashed and they stopped iptables and I was able to SSH again. So what I did was I re-installed CSF.

But now When i start iptables I'm getting

Code:

root@123[~/csf]# service csf start
Starting csf:iptables v1.3.5: Unknown arg `-j'
Try `iptables -h' or 'iptables --help' for more information.

When I checked /etc/sysconfig/iptables it shows last line

Code:

-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited

Should I remove this line? Again started to getting this same LFD alerts. So I stopped LFD for now.


I need some help here to narrow down this issue

Thank you in advance

Additional detail : now when I start csf, my httpd going down
Outage reason: name lookup timed out
if I stop csf then httpd is up
