How do I see if memcached is already running on my chosen port?

Question

I am having some problems with memcached and one idea I am having is that perhaps it is already running on the port I am trying to run it on, started by some other user on our network. Is there a way to tell what memcached ports are currently in use?

Answer 1

To see if it is running you could also try telnetting into the port:

telnet localhost 11211 

If this works you will see the following (telling you that the given port is open):

Connected to localhost. Escape character is '^]'. 

Now if memcached IS running you can see some basic stats by issuing the given command:

stats 

If this fails you will know that memcached is not running.

Answer 2

Try

netstat -ap | grep TheChosenPort# 

and see if anything is listening on those TCP or UDP ports.
