GRID::Machine seems to use ssh and passwordless keys already, so I'm not sure where your problem is, exactly. Maybe you can explain a bit more verbose what problem you are trying to solve.	[reply]

Hi, the problem is that i need to ask user and password because many people should use the script and it is not wished due to security reasons that there is a automatic authentication...sucks, but its a rule :[ the final goal is to use a SSH connection to a server, from there a second SSH connection to an other server and from there via telnet to a switch...each hop with authentication Oo im already working so fucking long on this, and thats the last step :DD Regards	[reply]

I still don't see the problem. This is most likely because you haven't described the whole situation. I think a current solution would still be to give everybody their own, passwordless key and make them use their personal key when they launch the script. I don't see why your construct of multiple SSH/telnet hops is necessary, but it can easily be eliminated by launching `netcat` as the remote shell to do the direct ssh tunneling.	[reply] [d/l]

Hello bgi, Automatic authentication is safer that password authentication if you use a passphrase for the identity file and is the preferred method by experienced admins. To have automatic authentication and passphrase working toghether you must: Generate the pair private-public key with passphrase and use `ssh-agent` and `ssh-add`. Once you have authenticated against the "agent" all the connections will go without any additional passphrase typing. Also, hide all the connection parameters inside a section of your `~/.ssh/config` file. Something like this: `... Host rbeo user otheruser Hostname localhost Port 2048 IdentityFile /home/pp2/.ssh/ursu ...` [download] This is the recommended way when working with GRID::Machine (rather than giving a lot of parameters in the call to the constructor) Hope it helps Casiano	[reply] [d/l] [select]

Yes, you can. But then you have to type the password each time you create a new connection ...	[reply]
