Push branch using SFTP throught a firewall

[Eric Fesler]

Thanks Martin for your reply.

I tried 
   
  ssh -p 522 hostname bzr --version

and got the following response

Bazaar (bzr) 0.15.0
Using python interpreter: /usr/bin/python
Using python standard library: /usr/lib/python2.5
Using bzrlib: /usr/lib/python2.5/site-packages/bzrlib
Using bazaar configuration: /home/eric/.bazaar

The target host is still a Breezy version (I know I should upgrade but I
can't find the time for now ;-) )

I retried

    bzr push --create-prefix
sftp://eric@<hostname>:522/home/bzr/voixautobe

and here is the content of the log file:

Any idea?

I don't think this is due to the target host since it's working properly
with a Windows client using bzr 1.4.
