With a fresh build from cvs today and the last several days tramp seems to hang
after a connection to a remote machine. Here is output from messages:
n
Tramp: Opening connection for me@somehost using plink...
Tramp: Waiting 60s for local shell to come up...
Tramp: Sending command `plink somehost -l me -ssh && exit || exit'
Tramp: Waiting for prompts from remote shell
Tramp: Found remote shell prompt on `somehost'
I have changed the hostnames obviously. This same behavior can be reproduced on
my GNU/Linux system at home. I have tried ssh and scp methods with tramp as
well. In each case I come seem to get into a loop after the message Tramp:
Found remote shell prompt on `somehost'. by checking out at 10/22/2007 (cvs
update -D 10/22/2007) tramp works as expected again. I can see from the logs
that there has been a lot of changes in that time. Please let me know if there
is any other information or debugging steps that I can take to help.

I do not understand completely. Does it mean it isn't a Tramp issue, and
you have a broken .ssh/authorized_keys file on the remote host? Or does
it mean Tramp is no longer able to login when authentication goes via
the .ssh/authorized_keys file?
Best regards, Michael.

Sorry for being unclear. It still seems to be a tramp issue. I set
debug-on-entry and stepped through opening a file on a remote host and it seemed
to get into a long loop of trying to recognize the remote prompt. I know that
the connection was made via tailing syslog as well as seeing the shell session
via ps. I'm pretty green with elisp, is there a way to dump the debugging
session? Is that something that would help?

One other thing it seems like the large checkin on the 27'th seems to be where
the change that caused this issue happend. There seemse to be quite a few
changes there. but if I roll the tramp files back to 2007-10-27 then I am able
to connect and edit files just fine if I update to the 28th it stops working.

Could you, please, apply (setq tramp-verbose 8) and rerun the test? I
would like to see the resulting buffer *tramp/ssh ...* and
*debug tramp/ssh ...*.
Best regards, Michael.

I ran tests on machine's both at work and home I put the results at:
http://www.ilstu.edu/~abturet/tramp_debugging/
Thank you for looking at this, tramp is an excellent feature of emacs.

Thanks a lot, that's instructive. Your shell prompt contains escape
sequences, Tramp (with its recent patch) has problems with.
Could you, please, apply the appended patch? It won't be the final
patch, I just want to know whether I'm going into the right direction.
Best regards, Michael.

I applied the patch and I get a regexp error:
tramp-wait-for-regexp: Format specifier doesn't match argument type
I updated the page to have the debug outputs:
http://www.ilstu.edu/~abturet/tramp_debugging/
as well as ouputs from rolling back to 10/27 incase that's helpful
