Is this OpenSSH?  If so, which versions?  It looks like a fairly old one
since the config file didn't have any mention of SSH v2 options.  It
might be worth upgrading to the latest version of OpenSSH and using SSH
v2.

In the mean-time, are you using the SSH agent?  There are options to
force the use of the agent and vice versa.  Also, run ssh which the
options "-v -v -v" to give maximum debugging information.  Depending on
what you have in ~/.ssh/config you may want to try the option "-1" to
explicitly force protocol v1 (unless you upgrade as advised above).

Personally I've found SSH to be really fussy about the options it
accepts, despite claims made in the documentation.  Plus the error
messages tend to be really unhelpful (as above!).  Having said that, if
you fiddle with the options enough it will generally end up working. :)

If you're still stuck after trying all these things then consider
posting the output from when you run with the "-v -v -v" option.
