Description
How to avoid ssh prompt from requesting 'Press enter to Continue' message?
Some scenarios will result in the ssh prompt showing a 'Press enter to Continue' message.
This can affect automated scripts which are not expecting to press enter to logon.
One such scenario will occur if you have 'ChallengeResponseAuthentication yes' configured in sshd_config and the client is in the disconnected state.
Example message when in this situation:
--------------------
Password:
You have logged in using cached account information. Some network services
will be unavailable.
Press Enter to Continue.
-------------------- -
Resolution
A new vas.conf option was introduced from Safeguard Authentication Services version 5.0.3 onwards to suppress this message:
-----------------------
[vas_auth]
ssh-no-extra-prompt = true
-----------------------
This can be set with the following command:
# /opt/quest/bin/vastool configure vas vas_auth ssh-no-extra-prompt true
Man page entry for this option:
-----------------------------
ssh-no-extra-prompt = <true | false>
Default value: false
By default some messages sent to the ssh client will display a "Press Enter to Continue" message and wait for the user to press Enter key before continuing.
Setting ssh-no-extra-prompt to TRUE will suppress this behaviour and never expect an extra Enter via ssh.
[vas_auth]
ssh-no-extra-prompt = true
----------------------------- -
Additional Information
This 'Press enter to Continue' message will only appear when you have 'ChallengeResponseAuthentication yes' configured in sshd_config.
