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

[santosh kumar]

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,

santosh D

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'
