Rats do you remember what they said about mmap?

Here is the server watching me log back in from an unpatched
box, to my nice shiny new sshd.

try turning off compression, especially if you're using a 2.2 kernel.

There was some stuff about it in the debian security announcement...

* compression does not work on all operating systems since the code
 relies on specific mmap features

however, solar designer has apparently released a patch for 2.2 kernels -
dunno where though! ;)

<doh> - for those catching up privsep has it's own README in the
new source tar ball, you have to make an empty chroot jail and
user.....yawn.

Make sure you enable PrivelegeSeperation in sshd_config, too ;)
