[Fab-user] Trouble running ad-hoc commands w/o having to re-enter password for each host.

[Waldbieser, Carl]

Sometimes, I want to just run an ad-hoc shell command on multiple hosts that 
requires elevated privileges.  E.g. I might want to grep a couple logs that are 
not world-readable.

    (fabenv)address@hidden fabrications]$ pip freeze
    Fabric==1.9.0
    ecdsa==0.11
    paramiko==1.14.0
    pycrypto==2.6.1
    wsgiref==0.1.2
    (fabenv)address@hidden fabrications]$ type fab
    fab is hashed (/home/waldbiec/projects/python/virt_envs/fabenv/bin/fab)
    (fabenv)address@hidden fabrications]$ fab -H ldap4,ldap5 -- sudo echo 'a 
test'
    [ldap4] Executing task '<remainder>'
    [ldap4] run: sudo echo a test
    [ldap4] out: [sudo] password for waldbiec: 
    [ldap4] out: a test
    [ldap4] out: 

    [ldap5] Executing task '<remainder>'
    [ldap5] run: sudo echo a test
    [ldap5] out: [sudo] password for waldbiec: 
    [ldap5] out: a test
    [ldap5] out: 


    Done.
    Disconnecting from ldap4... done.
    Disconnecting from ldap5... done.
    (fabenv)address@hidden fabrications]$

So I had to type my password in 2 times, even though it is the same on each of 
the 2 servers.  Am I doing something wrong?
