You know, I don't like to sound stupid, but I've tried to set this up,
and I've never gotten it to work reliably. Inevitably I get frustrated
and go back to password based ssh. Is there an Idiot's Guide to
setting this up somewhere?
Uh, mount the USB stick somewhere and use something like:
ssh -i /path/to/usb/stick/name-of-your-identity-file user@host
e.g.
mkdir ~/usbstick
mount /dev/sdb1 ~/usbstick
ssh -i ~/usbstick/my_id_rsa_file rick(a)somehost.tld
I believe the identity file must still have the right permissions (0600
or "rw-------" and that it's the identity file, NOT the public identity
key file.
