django - fabric and git ask me passphrase -

-

i'm using fabric automate deploy.

if connect ssh production server:

freelance@freelance:~$ cd /var/www/freelance/ freelance@freelance:/var/www/freelance$ git pull up-to-date. freelance@freelance:/var/www/freelance$ git pull up-to-date. freelance@freelance:/var/www/freelance$ whoami freelance

git don't ask me (because have set keys on bitbucket).

but if use fabric, works, ask me passphrase:

(ve)bepxxx-3411:freelance d$ fab git_pull   [peaidjosparino.cloudapp.net] executing task 'git_pull'   [peaidjosparino.cloudapp.net] run: git pull [peaidjosparino.cloudapp.net] passphrase private key:  [peaidjosparino.cloudapp.net] login password 'freelance':  [peaidjosparino.cloudapp.net] out: up-to-date. [peaidjosparino.cloudapp.net] out:    done. disconnecting peaidjosparino.cloudapp.net... done.

the user same, server same.

any ideas?

update: uname -a

(ve)bdxx-3411:freelance d$ fab test_prova [peaidjosparino.cloudapp.net] executing task 'test_prova' [peaidjosparino.cloudapp.net] run: uname -a [peaidjosparino.cloudapp.net] passphrase private key:  [peaidjosparino.cloudapp.net] login password 'freelance':  [peaidjosparino.cloudapp.net] out: linux freelance 3.13.0-24-generic #46-ubuntu smp thu apr 10 19:11:08 utc 2014 x86_64 x86_64 x86_64 gnu/linux [peaidjosparino.cloudapp.net] out:    done. disconnecting peaidjosparino.cloudapp.net... done.
