Hello @atitagain 

The welcome banner is located here and can be edited: 

/etc/ssh_banner file

I’m not sure if it will be changed back every time you upgrade.

Kind regards

Albert Williams

thanks for your reply - can I just delete ssh_banner file ? 

Hello @atitagain 

I have never tried but its not going to brick the machine if you do.

Might just get an error instead of the banner. Give it a crack. Or rename it to _old to see the impact. 

Kind regards

Thanks for your help
