my machine is running on Ubuntu 12.04 LTS. I installed apache 2 on my system. When I try to start it, I get error
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
Now this is very common problem regarding apache. most solution are to hit command
netstat -nltp | grep ':80' then get pid and kill the process. Linux gods are angry in my case I think. When I hit the same command, I get this output.
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp6 0 0 :::80 :::* LISTEN -
As you can see there is no pid for this process. How can this be? I have restarted machine many times it jst reappears. There is no way for me to kill this process. Please help.
