Note that you, portage and root are 3 different users, so you must make |
| 18 |
key pairs for reach on each source machine you will ssh from. |
| 19 |
|
| 20 |
Then you need to add each of those user's public keys to each |
| 21 |
destination user's authorized_keys file on each machine you want to ssh to. |
| 22 |
|
| 23 |
That can be a lot of key copying :-) 3 x 3 x # of machines |
| 24 |
|
| 25 |
Finally, on each machine you will ssh from and as each user who will do |
| 26 |
the ssh'ing, you must run keychain at least once to store the key creds. |
| 27 |
They should then persist until reboot, when you must run keychain again |
| 28 |
for each user. |
| 29 |
|
| 30 |
The idea is that a given user's keychain creds are valid over all that |
| 31 |
user's login sessions on a machine. User's cannot share each other's |
| 32 |
keychain |
