Ssh
From James's Wiki
sudo nano /etc/sshd_config
ssh-copy-id -i ~/.ssh/id_ecdsa.pub someuser@192.168.1.42
or
ssh-copy-id -i ~/.ssh/id_ecdsa.pub -p 1234 someuser@192.168.1.42
ssh-keygen -t ecdsa -b 521
I stumbled across this...need to test it out:
Just define your non-standard ssh ports in ~/.ssh/config file like so:
Host 192.168.1.103
Port 1431
Now all ssh based tools will just work without any extra command line hassle.
