Hi Ram,

Getty itself is responsible for displaying the contents of this file based on the definitions in /etc/gettydefs. But this is only true for console.

getty will not come into picture for telnet. You will need to add -b /etc/issue to the telnet line in /etc/inetd.conf and refresh inetd.

The file /etc/issue is used by the console (from /etc/gettydefs - getty) and the telnet request. The telnet request is based on the contents of the /etc/inetd.conf file. Add this at the end of this line of the /etc/inetd.conf:
telnet stream tcp nowait root /usr/lbin/telnetd telnetd -b /etc/issue

Don't forget to restart inetd
# inetd -c

Hi,

I am not sure if I understood your requirement. If you have an /etc/issue file, then it will overwrite the default banner displayed by telnetd or getty. /etc/issue is the only way to overwrite the banner and you will have to hardcode the model/hostname in there. There isn't anyway you can automatically generate it as it is an ascii file. Or delete the file and the corresponding process will take care of displaying the banner with hostname/model/OS etc.,

getty is a process reads /etc/issue file display on standard console there. It can not be for user terminal connrection.

It is a read content file so that we can not use it as shell script there.

see the permission of file 444 only. So if you want to have hostname / system informations etc there, you have to enter there, it would be display when login with console right there.

Else if you want to be display for every user then, do as,

/etc/profile

# Issue file display
[[ -f /etc/issue ]] && cat /etc/issue

so that it will be displayed to everybody.

And contents on /etc/issue are as like README file there.

HTH.
