I ignored my linode on host28 between April and now, and apparently there's hell to pay ;->
The thing is, I can log in fine using lish and a screen. But ssh ain't working. sshd seems to launch fine, and
Code:
ps aux | grep sshd
gives me
Code:
root 2440 0.0 1.1 3292 1416 ? Ss 02:47 0:00 sshd
But when I go to log in, I am denied access, with the same username/password combo (for root) which works on my screen session.
I tried once using sshd -d and here is the transcript:

What's even weirder is what happens when I try and ssh in from my old university account:
Quote:
apocalypse ~ [159] ssh li9-121.members.linode.com
Local: Bad packet length 1349676916.
apocalypse ~ [160]
Here is the linode side of that connection attempt:

In the second case it looks like the machine my account is on needs a newer ssh client, or something. But I don't get the first case. My machine is on a new network but even setting MTU to 576 on both my linode and home router does not solve the problem. Also I can ssh just fine into lish and other hosts.
Any clues?
Thanks for any help ...
PS I saw the May 30 thread RE sshd and tried the same mojo on /dev/null to no avail ...
