SuSE

I installed Apache2 and Gadmin-Httpd on Suse after installation I got a error message no listening sockets available when start apache.

Please advise, I check lot of forums but unable to find solution

I've seen this, in my case I had another HTTP server listening on port 80. Check with "netstat -na | grep 80" and look for listeners - other WWW server, skype or similar. Then disable it and restart apache. Else, you can always specify apache to run on different port, 8080 for example, but you have to access it everytime as : your-server.net:8080.
HTH somehow.

I do not see any application running at port 80, see log

s01:~ # netstat -na | grep 80

Then start troubleshooting apache itself, look at the logs, turn them on Debug level, see what they have to say. Again, make sure that no other application is running, that may interfere with apache's work. As a final resort, since I'm not sure what you've done, you may reboot the machine, and then start apache.

The problem is already fix, it was caused by the conflict between apache2 and gadmin-httpd it' s GUI management tool.

Thanks Anyway
