Customizing a Log In Banner
The ISR supports customizing welcome banners for users and user groups when logging into the system.
There are two options to customize a log in banner on the
ISR, using the
.bash_profile
or
using the
sshd_config
.
To enable a customized log in banner using the
.bash_profile
:
Note:
Each user has a.bash_profile
in the
/home/<user>/
directory. If the user is a root user, the
.bash_profile
is
present in the
/root
directory.
- Open
/home/<user>/.bash_profile
. - Append the following command
to access the banner message:
cat /home/<user>/banner
- Save and exit the
.bash_profile
file. - Open the
/home/<user>/banner
and enter the custom log in message you want to use. - Save and exit the
/home/<user>/banner
file. - Exit the current session and start a new one. The newly created banner message displays.
To enable a customized log in banner using the
sshd_config
:
Note:
Only root users, or users with sudo permissions, have editing permissions.- Open

before Banner and set the path to the banner.
