[Pvfs2-users] Re: Each time starting a pvfs2 server need a new port number

[Phil Carns]

Hi,

When you run your netstat check to see if anything is using port 9000, 
you should probably run it with these arguments:

	netstat -tan | grep 9000

The "-n" part of the netstat command line is important to make sure that 
you get numerical port numbers rather than symbolic names for them.  The 
"-t" makes it only show tcp ports, which are the only ones that matter 
to PVFS.

IANA indicates that port 9000 could possibly be used by something called 
"cslistener".  If opensuse happens to include that in their 
/etc/services file then you would see <host>:cslistener rather than 
<host>:9000 when checking netstat without the "-n" argument, and the 
grep would miss it.
