Ok, I have FreeBSD 5.3 running on one Alpha and Tru64 Unix on another.
Yet another machine runs OS X 10.3.7.
The simple problem is --
OSX and Tru64 have no trouble communicating via SSH.
OSX and FreeBSD have no trouble communicating via SSH.
Free BSD and Tru64 don't get along.
OS X runs: (from debug -vvv)
OpenSSH_3.6.1p1+CAN-2004-0175, SSH protocols 1.5/2.0, OpenSSL 0x0090702f
When connecting to Tru64 It reports:
debug1: Remote protocol version 1.5, remote software version 1.2.27
=======================
FreeBSD is running: (from debug -vvv)
OpenSSH_3.8.1p1 FreeBSD-20040419, OpenSSL 0.9.7d 17 Mar 2004
It dies before the "Remote protocol" message would be reported.
debug1: Reading configuration data /etc/ssh/ssh_config
debug2: ssh_connect: needpriv 0
debug1: Connecting to xxxxx [xxx.xxx.xxx.xxx] port 22.
debug1: Connection established.
debug1: identity file /home/magill/.ssh/identity type -1
debug1: identity file /home/magill/.ssh/id_rsa type -1
debug1: identity file /home/magill/.ssh/id_dsa type -1
ssh_exchange_identification: Connection closed by remote host
=======================
Tru64 is runing (-V)
SSH Version 1.2.27 [alpha-dec-osf5.1], protocol version 1.5.
Standard version. Does not use RSAREF.
and it fails (attempting to connect to FreeBSD)
xxx: Remote protocol version 2.0, remote software version
OpenSSH_3.8.1p1 FreeBSD-20040419
xxx Waiting for server public key.
Local: Bad packet length 1349676916.
(It connects to an OSX 10.2.8 system with no problem:
Remote protocol version 1.99, remote software version
OpenSSH_3.4p1+CAN-2004-0175)
=======================
"Obviously" its a version mis-match problem.
"Theoretically" I should be able to tell Freebsd to use version 1.5 ...
but that apparently isn't an option.
So the two questions are:
1- Short of upgrading ssh on Tru64 (assuming that there is a newer
version floating around, I haven't looked yet) is there a way to get
ssh on FreeBSD to talk to version 1.5?
2- Any idea what the "Bad packet length" problem is all about?
Will "Mac hmac-md5" fix that problem?
T.T.F.N.
