As with most Ubuntu installations (I run it on my laptop), sshd (the
secure shell daemon) is not enabled by default.  Normally one does not
need a ssh server on a laptop, though it's handy sometimes.  You can
check if it's installed by giving the "dpkg --status openssh-server",
and if so, whether it's enabled by "/usr/sbin/sysv-rc-conf --list ssh"
(if the output includes "2:on" it's enabled).

Eric and Wes are correct though in recommending you start with

    aips tv=local

as that's the most sensible option for (mostly standalone) laptops, and
does not require the ssh daemon to be running.

You can also start aips with:

   aips tv=local tpok

which bypasses the startup of the TPMON daemons altogether.

This shows clearly that the ssh server is not enabled.  Again, I really
doubt that you need it.
