SSH Access in Ubuntu 19.04

If you experience CLI or netconf-console SSH issue after installation of ConfD in Ubuntu 19.04, you can use solution described here:

Ubuntu 18.04 unable to ssh to ConfD ssh server

When connecting via SSH using an Ubuntu 18.04 client, the ConfD ssh server closes the connection after the connection has been established. This does not appear to be due to failure of cipher/KEX negotiation since the connection is established, then closed by the server. And it does not appear to be due to a firewall, as an Ubuntu 14 client works fine. Enabling the confdLog and developerLog debugging on ConfD doesn’t provide any additional information. Is anyone aware of a possible cause for Ub…

Go to $CONFD_DIR/etc/confd/ssh and issue command

ssh-keygen -v -f ssh_host_rsa_key -N "" -t rsa -m pem

Looks like after fresh install libssl package is of version 1.1. ConfD (7.1) needs version 1.0.0.
This can be fixed with:

echo "deb http://security.ubuntu.com/ubuntu cosmic-security main" >> /etc/apt/sources.list
apt-get update
apt-get install -y libssl1.0.0

If you upgraded from previous version (18.10) and had libssl1.0.0 installed, this is not need.

@mnovak

ssh-keygen -v -f ssh_host_rsa_key -N “” -t rsa -m pem

This is not needed since ConfD 7.2
