ISPConfig running...but port 81 not listening

[SoMBS]

I recently installed Ubuntu and ISPConfig and had it running just fine. Accessed ISPConfig server on port 81 without issue. Now suddently I can not connect. netstat -tap doesn't show port 81 listening any longer. Restarted ispconfig_server still no good. Rebooted server...no good. I'm not sure what could have changed to cause this. Any suggestions?

If there is nothing listening on port 81, then the IspConfig server is not running.
Check the syslog /var/log/syslog, or the Ispconfig server log - /root/ispconfig/httpd/logs

I checked the syslog files and no entry about a warning or that ISPConfig is running or not running. So I started it and it returned it's now running. Output of netstat -tap below indicates it's not. The most recent thing I was doing was setting the server up to listen on port 8000 and added that to apache. Not sure if or why that would could this.

/etc/init.d/ispconfig_server start
Starting ISPConfig system...
/root/ispconfig/httpd/bin/apachectl startssl: httpd started
ISPConfig system is now up and running!

netstat -tap

Well I went in a commented out the line Listen 8000 in root/ispconfig/httpd/conf - httpd.conf and now it's running. I also have port 8000 listening correcty now it seems. See netstat -tap below.

I suspect you had the IspConfig server and the apache2 server both attempting to listen on port 8000, and the Apache2 main webserver got in first.

[SoMBS]

Yeah it seems so. Now I only have the ports.conf file in apache2 directory listening on port 8000 in addition to port 80 and 443. This is working the way I need it to. Good learning situation. Thanks for your feedback.
