ipv6 and Tramp.

ipv6 and Tramp.

[Óscar Fuentes]

I'm trying to access a host through ipv6 with Tramp.

Which is the syntax? This complains about "Not a Tramp filename"

/[some:ip:v6:address:for:tramp]:/

I'm using Emacs 23.0.60.1 built 2008-09-27 on Windows XP.

I've added the code to tramp.el today.

With your next refresh of Emacs 23, it shall work.  I haven't tested it
on Windows XP (I don't run it); maybe you can report whether it's OK.

Best regards, Michael.

What happens, if you call "plink x:x:x:x:x:x:x:x -l ofv -ssh" in a
command window? Maybe there are problems in general with IPv6 addresses,
if you are on a w32 machine?

Yes, please do.

FATAL ERROR: Network error: Connection timed out

putty.exe with the same arguments connects just fine.

I've just checked the manual pages of plink. There is an option to force
IPv6 addresses.

Does "plink x:x:x:x:x:x:x:x -l ofv -ssh -6" work for you?

Do you have a PuTTY profile for address x:x:x:x:x:x:x:x?

Best regards, Michael.

No, same error. putty.exe autodetects the address type, it does not
require -6.

Yes. The connection fails no matter if pageant is running or not.

This seems a buggy plink.exe. I'm using the latest release (0.60).

plink can also handle PuTTY profiles. This is implemented in Tramp as
method "plinkx".

Does it work, if you open in Emacs "C-x C-f /plinkx:profilename:" ?

I guess that you mean "saved sessions" here. There is no mention to
"profiles" on the putty help file.

Nope.

C-x C-f /plinkx:osx: ENTER

Tramp: Opening connection for osx using plinkx...
Tramp: Waiting 60s for local shell to come up...
Tramp: Sending command `plink -load osx -t env 'TERM=dumb' 'PROMPT_COMMAND=' 'PS1=$ ' /bin/sh && exit || exit'

Yes, likely I do mean this :-)

But it works when opening PuTTY, you say.

Well, we need more traces. Could you, please, set tramp-verbose to at
least 6? Then rerun the test, and maybe we see more interesting
information in the traces. Please show the corresponding buffer "*debug
tramp/plinkx osx*".

Just for curiosity: Does Tramp/plink connection work for you to other
hosts, which are not addressed via IPv6?

Thanks in advance, and best regards, Michael.

IPv6 address syntax is not supported in Tramp [yet]. I'll add it to
the todo list.

Using IPv6 addresses literally would be a nightmare, because ":" is
already taken as delimeter. Maybe your proposal (surround it by "["
and "]") is a good compromise.

Best regards, Michael.
