Hi,

If for example i try to start tomcat in a solaris server and get errors related to address already in use, how can I know if this port is really used for another process?

If someone can point any documentation it will be very helpfull.

Thanks! :rolleyes:

# netstat -rn

Is it show routing?

I think you want to type "netstat -a" right?
