I just tried (version 3.3.6):

% telnet localhost 7100
Connected to localhost.
Escape character is '^]'.

and nothing happens. I quit telnet and xfs still runs.

HOWEVER, I've been having problems this last week with xfs
disappearing several times, with about 25 xterms getting off line due
to this :-( There are no traces.

I'm running xfs under a 'xfs' account, not root. I had to set
client-limit = 50

so that it doesn't self-clone, because whenever it tries to self-clone
it crashes. I don't know if it's because I'm running it not as root. I
didn't dare to try...

BTW, the debian package doesn't allow to run xfs under another
account, I had to hack it manually...
