Paramiko SFTP autologon using id_dsa.pub

[Mike Hjorleifsson]

I wrote a lil module using paramiko's module to send a file via
sftp.. it works great using the username and password.
I would prefer to use id_dsa.pub to have an autologon and not save
the
password anywhere on the disk.. I cant find a good example of this.
Can anyone help ?

When you have an ssh-agent running that has the key loaded, paramiko
will automatically use that. If you don't have an ssh-agent running,
you have to pass either the pkey or the key_filename argument; the
former should be a PKey object (either RSAKey or DSSKey).

Thanks for the response, is there an example bit of code somewhere i
could digest ?

I did

c.connect("<hostname>",username="loewis")

with ssh-agent, and it worked just fine.

sorry i meant a code example that i pass the id_dsa.pub file contents
too
so i am not reliant on the host system to have the ssh-agent.

Hi Mike,

If you download the Paramiko zip archive:
http://www.lag.net/paramiko/download/paramiko-1.7.2.zip

You can find examples of loading and using public/private keys for
automated logins in the code under the "demos" sub folder.

Cheers,
Todd

c.connect("<host>",username="loewis",key_filename=".ssh/identity")

works for me with ssh-agent disabled.

wow been going nuts here after cutting and pasting to get a working test
so i ran demo.py ... and its not me.. i changed the hostname for
obvious reasongs, the id_dsa file does exist. i can sftp from bash no
problem. there is NO password on the key

Any ideas ? here is what i get.

Hostname: xxx.example.com
*** Host key OK.
Username [root]: isoaccpc2
Auth by (p)assword, (r)sa key, or (d)ss key? [p] d
DSS key [/root/.ssh/id_dsa]:
