define origin.
locating the server isn't too hard. if ndb is properly set up, then this should work
if '#ec/nobootprompt' or '#ec/bootargs' is il or tcp, then
; ndb/ipquery sys $sysname fs
fs=lyons.quanstro.net
else it's local, and you're done.
alternate method (potentially less reliable):
1. grep '[ ](#s|/srv)/boot'. if any process has it open, it's the file server, else
2. find a tcp or il connection with remote net!*!9fs, and that's your file server.
when in doubt, it's likely the lowest numbered fs.
