You don't need 17010 as drawterm still uses the old cpu negotiations.
I also don't think you need 564. Drawterm is the fs and everything runs
on the cpu.

[andrey mirtchovski]

there are examples of using IPtables for port forwarding drawterm, fs,
cpu and other connections.  see the archives from august (24th and
earlier) 2003, subject is "NAT'ing a drawterm connection"

drawterm doesn't support encryption. Device '#a' (and '#D'?) need
to be implemented in it or ported.

[steve-simon]

cpu(1) is encrypted, as is import(1).

accessing a file server directly is not at present...
though this won't effect you running drawterm.

[9fans] drawterm through nat

[Matthias Teege]

Moin,

is it possible to drawterm to my nated home plan9
network? I have access to the nat gateway and
can setup port forwarding. Which ports are needed
for drawterm? Is the connection encrypted?

I am forwarding 564 (9fs), 567 (ticket), 17010 (ncpu), and 17013 (cpu)
through my Netgear router to my home cpu/auth server and can use
drawterm to connect from my workplace.

I think you don't need all of them open, but I haven't experimented.

> Is the connection encrypted?

There was a thread a couple of months ago, which I believe said that
the connection is not encrypted.  Somebody was going to look into
upgrading drawterm.

yes, afaik.  it's just tcp.

up in the 17000 range, but i'm too tired/lazy to check.

> Is the connection encrypted?

no, but the authentication is.  tcp-hijacking [hi ECHELON]
is doable, but kinda impractical.

it's pretty impressive (save for those stupid 'postnote' windows
which essentially say 'bust').  it's a bit unforgiving when net delays
are exceeded.  i've drawtermed from sydney to NY and paris to NY.

i'd like to re-write it in limbo, but my list of things i'd like to do
is getting rather long ...
