Re: [Fab-user] ssh -i && env.key_filename

It sounds like that user is not allowed to run shells.  Try setting env.shell to an empty string.  You'll lose the ability to use any shell specific commands via run but what you're running in your example should be fine.

if i am trying to connect over a normal ssh connect it working good.

how to use the "-i" option in fabric, do we need anyother options ?

for me fabric is working good with a username/password , code is good. Just that i am not able to use the sshkey in the fabric file.

Thanks,

I would work backwards by first figuring out what the sysadmin did to restrict login on the server, that info will help you figure out why ssh client works but fabric/paramiko doesn't.  Or maybe you are doing something funny in `exec_remote_cmd`.

All,

I have done all the set up for the private and public keys. Later when i am using the ssh keys it working as expected.

 ssh -i latest_my_node_rsa address@hidden 'sudo /usr/bin/virsh list --all'
