I see two kinds of error messages here:

1. The message and TEK servers run as programs running in xterm terminal 
servers.  This program "xterm" does not seem to be available on your 
system.  If you set the  AIPS_MSG_EMULATOR  environment variable to some 
other type of server that is available on your system, the message 
server should work.  The TEK server uses the AIPS_TEK_EMULATOR 
environment variable but only terminal drivers that support tektronix 
emulation will do.  I am told that there is a replacement for xterm 
called nxterm - perhaps that is available on your system and can be used 
by setting these environment variables in your login or aips startup 
procs.  If not you will need to install xterm from somewhere - it is 
probably an optional function from your install disk.

2. The "Address family not supported by protocol" is a new error message 
for me.  Very strange.  Try using UNIX sockets rather than Inet ones:
say   AIPS TV=local on your aips command line.

More info on these are in help files on AIPS, MSGSRV, and TEKSRV.
