If you have SSH installed (which is part of Cygwin), then you can use it
to tunnel a connection through the firewall from the squeak terminal to
the remote host.  It is a touch obscure, but it worked fine on the
firewall I was resticted by.  It also has the added benefit of
encrypting your password and session.

ssh -2 -N -L23:localhost:23 username at squeak.org

You then connect simply to "localhost" from the squeak session, and you
will be greeted by a login prompt for the remote host.  The only problem
is that you have to give your password twice, once for ssh and once for
the squeak terminal login (there may be a way around this).

Yayy, Ian! Glad you tried it Brent - I couldn't get through the firewall
for trying it personally :-( Need SSL first :-)

Cheers,

The telnet stuff should now work on Mac and Windows too (assuming they
implement Socket>>setOption:value: correctly) but please let me know if
you try it on these platforms, since I haven't.

I tweaked performance in TtyMorph a little: it now runs at 20% the speed
of the real xterm.  It also comes with its own font now, infinitely
nicer than Atlanta.

Oh yes, I also added support for "connecting" to a pseudo tty.  IOW, it
now supports talking to a local interactive shell (that thinks it's
connected to a real terminal [which it is, although the terminal is
being emulated entirely in Squeak ;-] and so will work just like any
login shell should: job control, window tcset/getattr work properly [so
Emacs, less and friends will happily run], etc, etc...).

For the shell to work you need AsynchFilePlugin support and the (brand
new) PseudoTTYPlugin.  (It just so happens they're bundled in the new
3.2-3 Unix VMs. ;)

Hope you like it.  Enjoy!

Ian

PS: The PTYPlugin should work with any OS that provides Unix98-compliant
    ptys (I've tested it on GNU and Solaris).  Cygwin has them, but
plain
    Windows almost certainly doesn't.  (MacOS [version 9 and earlier]
    hasn't a rat's chance. ;)

PPS: If there's a real interest in this stuff then I could be persuaded
     to add some pages to a swiki explaining it all.
