Port 80 is in use by some process

Bill Fox · 01-17-2005, 11:27 AM

I am setting up Lotus Domino to run on Fedora Core 3. I have everything working fine except when I try to start the HTTP task on the Domino server it says that port 80 is in use by another process.
In the setup I have the Apache server disabled, but obviously there is some other process that has port 80 open.
Is there some way to query port 80 and determine what process has it open?

Thanks

A common first diagnostic step would be to telnet to that
port ...
telnet <host> <port>

Cheers,

sure !

Code:

netstat -l -n -p |grep 80

in case apache 1 is running on the machine it will give you something like this:

Code:

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN1973/httpd

with 1973 being the PID of httpd
