[gentoo-user] /etc/issue information

[Marco Calviani]

Hi list,
   using this page of the gentoo wiki http://gentoo-wiki.com/TIP_Console_Prompt
i'm trying to use the /etc/issue file.

After having enabled the file in the /etc/ssh/sshd_config file with

Banner /etc/issue

file i've observed that effectively the system shows the "welcome" string.
However i'm not seeing the effective system name, kernel etc.... but only this:

This is \n.\O (\s \m \r) \t

Password:

it seems that the escape character is not correctly identified.

What i'm doing wrong?

Regards,
MC

Not an answer, but an observation on my part of a similar behaviour:

On my box, the "first" load of the issue would display the right thing
(substituting the proper text for all the escape characters), but if, 
say, I type in an invalid username/password combo, login will wait a
few seconds (like it is told to do) and display the banner again. But
this time, the escaped characters will be displayed like what you
have there. But if I once again log-in correctly, and then log-out,
the banner displayed on that VC would be correct again. 

I can't figure out what's wrong either.

Those escape characters are recognized only by the getty program,
which is used for console logins.  You should still be able to use the
color setting escape sequences, since those are terminal escapes.  But
the substitution stuff is getty specific, and will not work with ssh.

thanks for sharing this info. It comes completely new for me. So, as
far as i understand, there is no way of having this info with ssh
login? Am i right?

Thanks,

The current time will be difficult.  But you could create a file (like
/etc/issue.ssh) with the rest of the information in it:

echo "This is `hostname`.`hostname -d` ( `uname -s` `uname -m` `uname
-r` )" > /etc/issue.ssh

You could put the above in local.start to update the hostname or
kernel version information at each boot.

IIRC, another choice is to emerge linux-logo. I believe it comes with 
a init.d script that does precisely that. And you can program in an
ANSI/ASCII banner while you are at it.

Look and see if you have an /etc/issue.net

All of my old RedHat boxes used that file to display a logon banner via
ssh.
