do a ctrl-Z to exit aips temporarily and cd /tmp

do an ls -laF

The tv=local TVs make files in /tmp for sockets

srwxrwxr-x 1 egreisen aipspgmr      0 Jan 15 17:26 LOK.1.primate=
srwxrwxr-x 1 egreisen aipspgmr      0 Jan 15 17:26 MSS.1.primate=
srwxrwxr-x 1 egreisen aipspgmr      0 Jan 15 17:26 TKS.1.primate=
srwxrwxr-x 1 egreisen aipspgmr      0 Jan 15 17:26 XAS.1.primate=

Note that these allow me and any member of the aipspgmr group to use the 
socket but not people who belong to the usual user group here 
(aipsuser).  If I somehow left these sockets behind when I quit aips 
then the next user on primate might find that they lacked permission for 
the sockets.  These sockets are for local TV number 1.  Try tv=local:4
for example to get sockets for number 4 (if that one is not in /tmp 
already).

If the socket files are not in /tmp then the permission denied is caused 
by their absence.  The start-up messages which you did not include 
should contain some sort of error in that case.
