I can add another banner to the ssh login stuff. it shows up before the password request. I did that.

How do I either replace or remove the one that comes after password.
Its just too much stuff?

I'm slightly confused by your question because I'm not sure what you mean by

If you want to change message that appears after logging through ssh edit /etc/motd. Or is this what you have already tried?

I added a banner by creating a file named banner.txt in the /etc/ssh directory. This file showed up before the login.

I will try the motd file.

Just tried it. YEP that was the file I was looking for.

Thanks.

the motd message will be displayed if you have the /etc/ssh/sshd_config: PrintMotd yes

Does anyone ever tried using automatic ssh authentication with authorized_keys2 ? I got it to work on Solaris and KNOPPIX 3.4, but not DSL.

Argh! That won't work with my sshd.

Any ideas?

Banner In some jurisdictions, sending a warning message before authenti-
cation may be relevant for getting legal protection. The con-
tents of the specified file are sent to the remote user before
authentication is allowed. This option is only available for
protocol version 2. By default, no banner is displayed.

I edited /etc/ssh/sshd_config and added a line to it: Banner /etc/ssh/banner. And of cource created that banner file.

I cant seem to edit the motd, is there a particular reason? Says I have a read-only file system. But I did (try to) change the /KNOPPIX in mtab to rw from the original ro. Still doesnt seem to help.

KNOPPIX is a compressed ISO9660 filesystem, which is read-only by design (like a cd session). You will need to remove the /etc/motd symlink and replace it with the real motd file. You will then need to add /etc/motd to your backup, or to a myDSL extension (same thing as a backup file, but with a different file name), in order to persist after a reboot.
