[OpenAFS] Re: list all AFS clients

[Christof Hanke]

Bascically what you do with this command is to check the active 
connections to one server.
Thus, if a client never spoke to that server or only a long time ago (I 
don't know the timeout), you will not get it.
So if you want to get all clients, you need to get a set of servers and 
be sure that each client talks reguarly to least one of them and then 
combine the results.
Thus, the only way to make it usable for everyone without any user 
configuration would be to get all servers with "vos listaddrs" and do 
the rxdebug-thing with all of them and then boil down the lists. It's 
not very efficient, but I guess it should work everywhere out of the box.
