lfd not starting - pid mismatch or missing

[ferdi2000]

I ran an EasyApache re-compile of Apache and a CentOS Yum update and since I can't seem to get lfd to start...
I reinstalled CFS from scratch following the guidelines, but after lfd starts it stops straight away... I can see the following in the error logs...

Code: Select all

root@host [~]# tail -f /var/log/lfd.log

Aug 30 20:56:37 host lfd[22089]: daemon stopped

I'm not sure what is causing this. If I manually start the lfd service, it stops with the above error too.

Running the tests came back fine:

Code: Select all

root@host [~]# perl /usr/local/csf/bin/csftest.pl
Testing ip_tables/iptable_filter...OK
Testing ipt_LOG...OK
Testing ipt_multiport/xt_multiport...OK

Testing ipt_recent...OK
Testing xt_connlimit...OK
Testing ipt_owner/xt_owner...OK
Testing iptable_nat/ipt_REDIRECT...OK
Testing iptable_nat/ipt_DNAT...OK

RESULT: csf should function on this server

Can't work out what might be causing this and I haven't found any similar problems on these forums. (CENTOS 6.7 x86_64 kvm – host WHM 11.50.0 (build 30))

If I run csf -r I get a failure too:

Code: Select all

root@host [~]# csf -r

After Flushing, I now see the following error in my lfd.log:

exec of /sbin/ifconfig failed - Must mean I do not have ifconfig installed... So as I found on this thread I ran "yum install net-tools" - But it said... Package net-tools-1.60-110.el6_2.x86_64 already installed and latest version ... So now I'm lost as to what to do? :P

[ferdi2000]

Well.. I managed to fix it, I noticied inside my /sbin/ folder I had both /sbin/ifconfig and /sbin/incfg/ - All I did was change the csf.conf file and set:

(line 2238 - csf.conf)
IFCONFIG = "/sbin/ifcfg"

(opposed to: IFCONFIG = "/sbin/ifconfig")

Weird my ifconfig file was 31,504 bytes - but the ifcfg was only 3,056 bytes

Worked fine after this!

My working ifcfg contained the following code if anyone needs to create this file.

Here the same error with a debian 8.1, directadmin instalation... See or your workarround works out for me. In my /sbin I see only the ifconfig file.

Nope, didnt do anything
