SSH Banners - Embedded

CP_SA — Tue, 10 Jul 2018 22:25:07 GMT

Good Evening -

Can anyone share the steps for creating an SSH banner in embedded GAIA? It is no problem on every other gateway/platform that we have - but I come to a 1450 (R77.20.75) or an 1100 (R77.20.60) and it is no dice. 1100s have an /etc/issue file that can be configured - but there appears to only be a symbolic link to the ssh location - which then points to what appears to be a complete 'symbolic pathway'?? /etc/ssh --> /var/ssh/ - so that would appear to rule out configuring sshd?

The 1450's seem to have the same symbolic link to ssh, but they seem to lack an /etc/issue file.

Thanks!

Ok - piece of cake - so i have my: set message banner on "text..................." and and everything works well. BUT, i realized that there is a mistake in the middle and I want to correct it - how is this accomplished? Normally I would just vi the file. How do I edit and individual line in the config? I tried <set message banner off> and then tried putting the correct banner back in - it just appends it and doubles it up?! How can I delete the original - there does not appear to be a command option delete banner / delete message?

Put the whole message again, but don't use "line on" on the first line:

set message banner msgvalue "Message Line 1" on
set message banner msgvalue "Message Line 2" line on
set message banner msgvalue "Message Line 3" line on
