ssh jump host

It’s claimed all over the Internet, here for example, that below works.

ssh -J username@host1:port username@host2:port

Bad stdio forwarding specification 'username@host2:port:22'
ssh_exchange_identification: Connection closed by remote host

You have to specify the destination host port with the -p option.

ssh -pdestination_host_port -J username@jumphost:port username@destination_host

Edit /etc/NetworkManager/NetworkManager.conf.

Add to the bottom of the file:


Save and run: systemctl restart NetworkManager
