Hi,

If I have a socket based server listening at a particular port. How do
I check this. Is there a command available which would tell me "Server
x" is listening at "port y"

Thanks and Regards,
M Shetty

use lsof.

bash$ lsof |grep LISTEN

java      26926   dynamo   13u  IPv4 0x30001328428       0t0     TCP *:48860 (LISTEN)

First field is the executable program's name, the second is the pid, and
the 48860 is the port.
