    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

    # Generated by iptables-save v1.4.7 on Thu Oct 23 01:38:58 2014

    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.
