[santosh kumar]

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 ***@chcilrsv130 'sudo /usr/bin/virsh list

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`.

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

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.

Thank you all.

Jeff,

you solution of using env.use_shell = False worked great.

Thanks,
