A posting to full-disclosure quotes Theo as saying HP and Cisco are affected,

be a good idea.....

Isn't this a common practice anyway? Has been anywhere sensible I've
seen :-)

I thought the whole purpose of running sshd on your router (or any box for
that matter) is to be able to access it securely from remote locations.
Of course, you could ssh to your patched unix box from outside (assuming
your internal network is ok), then ssh back to the router, but you might
as well just use telnet then (assuming a properly switched and vlan'd
LAN).
