We are here to help users get what they need and are happy to help.

The first issue has to do with your not having set up internet socket 
IDs so that Inet servers (TV, TEK, message) will not work.  The file 
/etc/services defines these but you need root privilege to change it.
You can start AIPS with
        aips tv=local
which will make Unix sockets (in /tmp) instead.  This should work - but 
let me know...

There is an issue with FILLM in the file naming.  It appends the file 
number after the character string - note that it said _21 when it ran.
The help file goes into detail about this.  Set

datain = '/home/stavros/DATA/STAVROS-LAPTOP_1/AO84_

and then set NFILES properly ( = 1 for file _2).

FILLM said 0 vis from 0 files so PCAT should not find anything.  FILLM 
will say the output file name and other details when it works.
