That doesn't make sense, given that "sftp -1 savannah" works, while
"sftp savannah" doesn't.  the .ssh/config file is being read.  I
followed your suggestion and ran sftp with -v enabled.  Before showing
you the results, I will comment on one thing:  What the heck is
"compatibility mode 1.99" and why would it leap to it.  And why isn't it
looking at my default protocol 1 key .ssh/identity?  It is looking at
.ssh/id_dsa, which isn't supported by protocol 1, so it then dumps me at
a password prompt.   Just to make sure, I added the line

   IdentityFile $HOME/.ssh/identity

to my .ssh/config, but that didn't help at all.

When I say sftp isn't working for me, what I mean is, it is demanding a
password.  On the Savannah server itself (not the website), there are no
passwords.  Authentication is by ssh key or nothing.

Just in case there is a permissions problem, here is the listing of my
.ssh directory:

address@hidden:~$ ls -l .ssh/*
-rw-r--r--    1 djw      djw          1680 May 29  2002 authorized_keys
-rw-r--r--    1 djw      djw          3234 Jul 18  2002 authorized_keys2

Here are the debug messages, I hope they help.
