How can I find out what version of ssh is running on a Lantronix device or console server?

---

You can determine what version of ssh is running on a Lantronix product (or any remote host) by using the -v (verbose) option of your ssh client.

E.g. if you are logging in to the Lantronix product from a Linux host using an OpenSSH client use this command:

ssh [hostname | ip address] -l [user] -v

Debugging messages will be displayed showing the negotiation between your ssh client and the ssh server on the Lantronix product. One of the debugging messages will look something like this:

debug1: Remote protocol version 1.99, remote software version OpenSSH_x.y.z

where "OpenSSH_x.y.z" is the version of ssh running on the Lantronix product.

EXAMPLE: ssh session to an SLC48 running v5.3b:

$ ssh 172.18.12.200 -l sysadmin -v
OpenSSH_4.3p2, OpenSSL 0.9.8b 04 May 2006 <-- This is the version of the OpenSSH client on your host.
.
. <-- Some debug messages-->
.
debug1: Remote protocol version 1.99, remote software version OpenSSH_3.7.1p2 <-- Version of SSH server on SLC
debug1: match: OpenSSH_3.7.1p2 pat OpenSSH_3.*
.
. <-- Some more debug messages-->
