Is it possible to display a message before login on Ubuntu?

On startup of my Ubuntu server, I have:-
Ubuntu 11.10 ubbuntu tty1

Ubuntu login: _

What Id like it to display is its IP address, so something like:-
Ubuntu 11.10 ubbuntu tty1
IP address - 192.168.1.32
Remote Administration on 192.168.1.32:10000
Default Username/Password: user1/pwd1

Ubuntu login: _
(Where its IP address retrived from DHCP id 192.168.1.32)


And then once logged in, display a message such as:-
This is a private server, if you should not be here, please leave.

Ive read that there are scripts that run at the times I need, but I dont know what they are, or what they are called.

I also dont know how to 'echo' out these commands, Im assuming something like:-
echo Remote Administration on 192.168.1.32:10000

Open in new window

, but I also dont know how to retrive just the IP address.

Sorry for not knowing much on this, and asking soo much on this one question!

Thank you

Believe me,

you really don't want to tell just anybody who's able to reach your server via telnet a username and matching password!

True, although really the purpose is to put the ip address in, so once the server is put in on site a keyboard isn't required to set it up, instead I can use another pc to configure a static ip and set it up.

Thank you

To customize your TTY login edit /etc/issue file . For more info
#man getty
To customize login messages edit /etc/motd file. its better to run a cron job for specific IP and dump the output to /etc/motd file
For Ex, in crontab,
10 * * * *  echo 'This is a private server, if you should not be here, please leave' > /etc/motd

Open in new window

This cron will run for very five 10 minutes and dump output to /etc/motd
