ssh-keygen f=FCr den User, der sich auf der Cisco einloggen soll. Den=20
Public Key auf die Cisco{,s} schieben -- als authorized_key.
Ab sofort sollte f=FCr diesen User Login ohne Passwort per ssh m=F6glich=20
sein.
danach den script nach folgendem Muster ab=E4ndern:
for cisco in $*
do
ssh [user@]$cisco <command> < [localinput] > [localoutput]
done
d.h. man kann jeden Befehl einzeln per ssh auf die Cisco schicken, dabei=20
wird In- und Output auf die eigene Maschine umgeleitet.
