Tunneling SSH

[SkOrPiOn`87]

Ciao,

Devo fare tunneling ssh, e per farlo ho creato un user aposta per ssh, e però dovrebbe entrare senza la richiesta di password, per fare questo ho fatto in modo di loggarsi con una Key...

ho creato la key:

ssh-keygen -b 2048 -t dsa -f keysuser

una volta fatto questa, devo configurare qualcos dentro il config ssh?

il client ssh con quale opzioni si deve connettere a me per avere il tunneling?


Grazie

Dai un occhiata qui e qui.

io che utilizzo SSH2 ho fatto:

ssh-keygen -b 2048 -t dsa -f keysuser

mkdir .ssh

cat keysuser.pub >> .ssh/authorized_keys
cat keysuser.pub >> .ssh/authorized_keys2

ma non è cambiato niente...
Questa operazione l'ho fatta bene?

Oppure devo fare anche:
cat keysuser >> .ssh/authorized_keys
cat keysuser >> .ssh/authorized_keys2

Grazie
