Hi guys

I’ve been running in some trouble to set banner in the DB server. Everything ok with app servers. Like this

thor@jump_host /$ sudo scp -r /tmp/nautilus_banner [email protected]:~/motd
[sudo] password for thor:
The authenticity of host ‘172.16.239.10 (172.16.239.10)’ can’t be established.

I can log DB server but can’t ssh copy to it and really don’t know why.

Any insight @Inderpreet?

Hi,

Try to install openssh-clients on the destination server.
