Bug Description

Summary of problem: on Windows running inside VMWare on Mac there is problem with paramiko: if user supplied wrong login name authentication failed with EOFError in ``File "paramiko\auth_handler.pyc", line 163, in wait_for_response``. Windows standalone installer uses paramiko v.1.7 (zubat) with ctypes modification (by Alexander Belchenko).

Original report:

Hi,
  I see some similar looking bug reports having to do with EOFError, but involving timeouts. I'm not seeing any sign of timeouts and I'm
getting these errors immediately. Below are three tracebacks from pull, missing, and branch commands. I have no problems dealing with
this server/archive from my Mac, but on Win32 I don't seem to be able to do anything without getting this error. For what it's worth, my Win32
machine is really a vmware instance running on a MacBookPro, but in general network access works fine from this "machine"; for example,
I'm filing this bug from Win32 Firefox running on the vmware instance.

Is it possible for you to open plain SSH session with Putty to that server and ensure
that SSH channel actually working without bzr?

Hi,
  I installed Putty and used it to connect to the server with an
ssh session. I didn't see any problems.

Ok. Can you test some more to help us understand this situation?

Can you run command again with -Dhpss flag and show us relevant part
of .bzr.log? I.e. command will looks like:

C:\kbasye\work\code>bzr -Dhpss pull --remember bzr+ssh://gpsrv4.hltcoe.jhu.edu/srv/bzr/

Can you try with sftp protocol and say is it work?

C:\kbasye\work\code>bzr pull --remember sftp://gpsrv4.hltcoe.jhu.edu/srv/bzr/

Hi,
  I did the tests. I didn't see any log file from running with -Dhpss.
When running with sftp, I got a different traceback, but the error looks like
the same one. Was I looking in the wrong place for the log file or ???

Usually log file resides in My Documents folder with the name .bzr.log.
Exact location is shown in the output of `bzr version`.

Thank you. I'm not sure but it seems like authentication fails for you.
I don't know for sure, may be it's because there is space in your login.

You have another option for using bzr+ssh in your situation.
If you say that Putty works OK, then you could try to use plink.exe
instead of paramiko. But bzr+plink does not support entering password
in the console, so you need to use pageant as well and server
should have your public SSH key in ~/.ssh/authorized_keys.

To enable plink you need place this executable in the folder listed in $PATH
and add environment variable BZR_SSH=plink

Hi,
   Thanks! I had completely forgotten that my Win32 install has this strange
login. On the server (and most of my other machines), I have a different
login.
When I went to the Win32 machine and used bzr+ssh://<my-real-login>@<server>
everything worked fine.

   So I think there are two problems. The first problem is user stupidity
caused by poor memory performance :->. The second problem is that paramiko
authentication failure throws this error. Just now, I tried
bzr+ssh://foo@<server> (there is no foo login on our server :->) and I got the
same error, so it's not really about the space in the login, I think.

   At this point I'm working again, which is great for me. I'll be happy to
help with more testing if you like; apparently the error is easy for me
to reproduce.

Umm...one more thing. I also just tried using the correct login (kbasye1) and
then giving a bad password. I got the error below. I can update the bug or
file a new one if you think that's necessary.
  Thanks again for catching my mistake,
     Ken
