How do you turn off login banner for non-interactive ssh?
I have a requirement to have a login banner for interactive ssh logins. However, the banner also displays for non-interactive commands. Basically I run a script to get me status of processes running on multiple computers. I would like to see the status without seeing a login banner for every system. Is there a way to turn off the banner for non-interactive processes? :confused:
Thanks |
cpatter...how about a couple of example commands here...1 on when you want the banner and one when you dont want it...I'm not quite clear on what you need...
Cheers Arvind |
I need the login banner when a user logs in via ssh.
ssh -l root nodename . When I pass a command I don't want a login banner. ssh root@nodename ps -ef . |

The question is 'a bit' outdated, but I have two solutions using a custom shell wrapper.
1. Using .authorized_keys command In ~/.ssh/authorized_keys you add the following before a specific key Code:
command="/usr/local/bin/shell-wrapper" ssh-rsa AAAAB3NzaC1yc2EAA...JZK1E8H60= Code:
#!/bin/sh Set shell for user (change USERNAME to your user): Code:
usermod --shell /usr/local/bin/shell-wrapper USERNAME Code:
#!/bin/sh |
@ koenpunt
Thank you for posting even when the thread was old,
I am in a fix, on one hand I cannot disable bannering from sshd_config and on the other hand brtools doesnt like the banners, so I am looking for a way to disable it for this one brtool user and I feel I am getting closer to finding a solution, with your help of course! can you please elaborate on SSH_ORIGINAL_COMMAND? |
I believe koenpunt's solution only applies to the banner produced by the remote shell, and not banners produced by the remote ssh daemon. Shells should automatically produce no banner unless invoked for interactive use.
If the problem banner is what the shell outputs, then there's nothing you can do at the local end but parse over this unusual thing. One way to do that is run a command line that the first command outputs an odd sentinel string that you can scan locally for to show only what follows it. If the problem banner is what the ssh daemon outputs, you might get away with redirecting stderr to /dev/null. If you need the stderr output from the command, redirect that to stdout. Code:
ssh userid@remote 'remotecommand args ... 2>&1' 2>/dev/null |
2>/dev/null
only banner is removed. |
Remove the motd
Try removing /etc/motd
There is an option in /etc/sshd_config to PrintMotd no which if turned to yes prints the Message Of The Day twice. |
Rather than removing the motd file, why don't you configure sshd not to print motd?
|
Code:
-q Quiet mode. Causes most warning and diagnostic messages to be suppressed. |
Code:
man ssh Code:
ssh -q user@host |
I thought it was as simple as
# touch .hushlogin in the users home folder ? |
