I want to use SSH between two computers on the same domain with the same user, and I don't want to type the password. here's an example:

```
[user@pc1 ~]$ ssh pc2

```

if *pc1* and *pc2* are on the same domain, with NIS authentication, and I'm logging in through SSH with the same user (as I didn't specify one), I wish I didn't have to type the password again, as I already did it when logging in at *pc1*.
