Which ones?  The AIPS Page is http://www.cv.nrao.edu/aips/ and my offsite
guest account (on goof.com, co-hosted by a company [BNT] in Blacksburg,
Virginia) can read it just fine as of a few seconds ago.

That (obviously) should not happen.  Did that user have write permission
to the various parts of AIPS needed (DA00/* areas, data areas,
$TST/$ARCH/MEMORY and contents, etc)?  If not, that would have caused him
or her to have aips fail to start.  But nothing like this should cause the
system to crash; I never saw anything like that happen in the years we ran
OSF/1 3.2 (we're now modern by NRAO standards and are running 4.0D on our
two remaining Alpha/OSF1 machines).  Are you sure it was AIPS that did
this and not some other action?

One good thing to do is cut out all the extra stuff on an AIPS startup:

    aips notv tpok pr=1

This prevents the TV (XAS, MSGSRV, TEKSRV, and TVSERV lock daemon) and
TPMON daemons from starting up, and gives you a bare bones AIPS session.

Do you have an entry for ssslock in /etc/services?  It should be:

ssslock		5002/tcp	SSSLOCK		# AIPS TV Lock

Check the file, and also try "ypcat services | grep ssslock" in case your
system is set up to use NIS/YP for the services map.

More services missing:

sssin		5000/tcp	SSSIN		# AIPS TV

> ZVTPO3: tcp/aipsmt0 is not a service

And more.  Here's a complete list that you can slap into /etc/services.

aipsmt0		5010/tcp	AIPSMT0
aipsmt1		5011/tcp	AIPSMT1
aipsmt2		5012/tcp	AIPSMT2
aipsmt3		5013/tcp	AIPSMT3
aipsmt4		5014/tcp	AIPSMT4
aipsmt5		5015/tcp	AIPSMT5
aipsmt6		5016/tcp	AIPSMT6
aipsmt7		5017/tcp	AIPSMT7
msgserv		5008/tcp	MSGSERV		# AIPS Message Server
sssin		5000/tcp	SSSIN		# AIPS TV
ssslock		5002/tcp	SSSLOCK		# AIPS TV Lock
tekserv		5009/tcp	TEKSERV		# AIPS TekServer

Though if there's a problem with the file, I'd look at a good system
backup to make sure there isn't more system damage to crucial files in
/etc/ and elsewhere.
