It's been my experience that once you let it change libc you're basically
tracking the next one up. Safer perhaps to
apt-get source ssh
...and only point your deb-src list at unstable; you get mapped against
the local libraries.

testing is -trying- to be stable, unstable really is testing the bleeding
edge. With the attendant chance of running into it and needing a bandage.
If you want to track unstable "a little bit" then I *deeply* recommend
keeping your apt-cache directory pointed into a really large disk space so
it doesn't flush older packages much ... or using an apt-proxy via a
disk-laden desktop on your network doing the same ... so you can reach
back for the mini-rev of the .deb file that *worked* when something goes

When sticking to stable, it's important to add
deb http://security.debian.org/ potato/updates main contrib non-free
...so you get packages that cover any security advisories debian had to
You can track unstable sources without tweaking your binary deb lines:
deb-src http://http.us.debian.org/debian unstable main contrib non-free
deb-src http://non-us.debian.org/debian-non-US unstable/non-US main contrib non-free
This is the part where library dependencies can get you instead, and apt won't
help as much.

The package named 'ssh' states boldly in its description that it is
OpenSSH and supports both SSH1 and SSH2. And I have been using it without
hindrance or care about which one the servers I'm touching were running.
ssh -V should tell you what version you've got, but there are lots of
commandline options. What message do you get back when you try to connect
to these SSH2 servers?
