Checking your IRIX patch level

These instructions only work in IRIX 6.5.22 or higher. If you are not sure what patch level of IRIX you are running, type uname -R:

% uname -R
6.5 6.5.22f

OpenSSH Installation while upgrading to 6.5.22 (or higher)

If you have not yet upgraded to 6.5.22, it's easiest to install OpenSSH during the patch install process. We now install OpenSSH when we upgrade machines to 6.5.22, so just follow the directions to Upgrading to the latest release of IRIX.

OpenSSH Installation after 6.5.22 is installed

If you have already upgraded to IRIX 6.5.22, you can install OpenSSH after the fact. You just have to re-do a few instructions from Upgrading to the latest release of IRIX

First connect to the share and start inst:

# mkdir /mnt
# mount strongmad.chem.indiana.edu:/data/export /mnt
# inst

Once inside inst, type the following:

from /mnt/IRIX/6.5.22
install openssh
go

Enabling OpenSSH

Once OpenSSH is installed, you have to flip the switch to turn it on. We'll use chkconfig to enable it. Enter the following as root: chkconfig sshd on

Migrating from SGI Freeware OpenSSH

If you've installed the OpenSSH version from http://freeware.sgi.com/ you need to disable it and copy your old keys over:

chkconfig fw_sshd off
cp /etc/ssh/*key* /etc/openssh/
