CSF Cluster Issue

[boog_nish]

Hello,

I was looking for a little assistance with my CSF cluster. There appears to be a strange issue that I can't seem to resolve. I currently have 1 Master server and 8 Slave servers connecting to it. I have properly configured each server, and ensured that they can all speak to each other. I have checked each server to make sure they are all listening on the correct port. When I attempt to send out a cluster ping test from the Master server, I am able to only ping the first IP that is in the server list. This happens no matter which IP is set to be the first one, so I know it isn't an issue of the servers not allowing communication. It is very strange and I was hoping someone else has resolved this issue before. My Master server will always send out the ping or command to the Slave server I have listed first and fail the rest. Please help!

Port Listening Check. Same result for all servers:
------------------------
# netstat -tunap |grep 7777
tcp 0 0 0.0.0.0:7777 0.0.0.0:* LISTEN 847792/lfd Cluster
------------------------

CSF Rule sent to Master from Slave with success:
------------------------
# csf -cd XXX.XXX.XXX.XXX PHP Hack
Sent to <MASTER_IP>
------------------------

CSF Rule sent from Master to all Slaves with failures:
------------------------
# csf -cd XXX.XXX.XXX.XXX PHP Hack
Sent to XXX.XXX.XXX.1
Failed to connect to XXX.XXX.XXX.2
Failed to connect to XXX.XXX.XXX.3
Failed to connect to XXX.XXX.XXX.4

That suggests an issue with IO::Socket::INET on the servers. I was unable to recreate a problem. Try changing this line in /etc/csf/csf.pl from:

Code: Select all

		eval {$sock = IO::Socket::INET->new(PeerAddr => $cip, PeerPort => $config{CLUSTER_PORT}, LocalAddr => $localaddr, Timeout => '10');};

to:

Code: Select all

		eval {$sock = IO::Socket::INET->new(PeerAddr => $cip, PeerPort => $config{CLUSTER_PORT}, LocalAddr => $localaddr, Timeout => '10') or print "Cluster error connecting to $cip: $!\n";};

Then restart csf and then restart lfd. You should now get more detailed information about what is happening in IO::Socket::INET.

Try removing your spaces between the server IP's in csf.conf
