Monyog-bin Is Running But Cannot Connect To Dashboard

[audetweb]

I am a new client testing out MONyog on a CentOS 6.6.4 VPS on the Jelastic cloud platform.

 

I am running the trial version and I do not have a license number in the MONyog config file.

 

The installation using RPM worked and the binary is running as a process.

 

[root@centos6 ~]# netstat -lnp

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name

tcp        0      0 0.0.0.0:5555                0.0.0.0:*                   LISTEN      826/MONyog-bin

 

[root@centos6 ~]# lsof -i :5555

COMMAND   PID USER   FD   TYPE    DEVICE SIZE/OFF NODE NAME

MONyog-bi 826 root   11u  IPv4 618066714      0t0  TCP *:personal-agent (LISTEN)

 

However, when I go to my web browser and type in the URL, I cannot connect:

 

http://aaa.bbb.ccc.ddd:5555

 

I get the following error message from Firefox:

 

The connection has timed out

The server at aaa.bbb.ccc.ddd is taking too long to respond.

 

I also checked the iptables:

 

[root@centos6 ~]# cat /etc/sysconfig/iptables

I am missing something obvious, like some firewall setting or maybe a bridge.  I am not a Linux expert but I can muddle through the command line.

 

I see that MONyog is listening on a local address (?) instead of the public IP address, is this right?

Am I missing a connection between my public IP address and the local LAN address?

 

Thank you.

 

UPDATE – Found a Solution

 

I removed the following two lines from the iptables configuration file:

 

-A INPUT -p tcp -m tcp –dport 5555 -m state –state NEW -j ACCEPT

-A OUTPUT -p tcp -m tcp –dport 5555 -j ACCEPT

 

I then added port 5555 to the list of ports on this line:

 

-A INPUT -p tcp -m tcp -m multiport –dports 80,443,8080,8022,5555 -m state –state NEW -j ACCEPT

 

I then restarted the iptables daemon and I was able to pull up the dashboard.

 

I still need to learn how to configure iptables, otherwise, the problem is solved.
