Ubuntu login and welcome message control / etc/issue and / etc/motd

The difference between / etc/issue and / etc/motd is that when a network user logs in to the system through a serial port, the file contents of / etc/issue are displayed in front of the login prompt, while the contents of / etc/motd are displayed after the user successfully logs in to the system.

Modify the pre-login display message:

The code is as follows:

# vi / etc/issue

# vi / etc/issue.net

Custom 10.04.2 LTS\ n\ l

The meaning of each code in issue:

\ d Local time date

\ l display which terminal interface

\ m display hardware level (i386 Universe i486 Universe i586 Universe i686...)

\ nShow host network name

\ o display domain name

\ r operating system version (equivalent to uname-r)

\ t display local time

\ s operating system name

\ v operating system version.

You can make your favorite login information by modifying / etc/issue content. Also note here that there is a / etc/issue.net in addition to / etc/issue. This is provided to telnet, the process login program. When we use telnet to connect to the host, the login screen of the host will show / etc/issue.net instead of / etc/issue.

The message is displayed after login:

The code is as follows:

# vi / var/run/motd

Welcome to Ubuntu!

There is a lot of system information shown here, how can it be obtained and updated?

Ubuntu is different from other linux, directly modify / etc/motd file after re-login invalid. Because here / etc/motd is a symbolic link to / var/run/motd, it should be a generated file after startup. In version 10.04, the generated script is found in the directory / etc/update-motd.d/, and the files with serial numbers are, including 00rel header.20 CPULI checker, 90-updates-available, 98LV rebootLite 10Helift textmat 50LTRALATEL Sysinfoe91LFO release-upgrade,99-footer. Modify these files to get the results you want.

After modification, use:

The code is as follows:

Sudo run-parts / etc/update-motd.d

If you execute it, you will see the effect immediately without having to log out repeatedly.
