yet another run-across-cluster script

[Joe Landman]

Hi folks:

  I wanted to give a quick pointer to a simple cluster tool I had built
a while ago (that I seem to use everywhere).  It is
yet-another-run-a-command across all the nodes, though it uses ssh,
doesn't require daemons (other than SSH), doesn't send passwords or
usernames, and so forth.  No, it doesn't do parallel dispatch (yet).

  You can pick it up at
http://scalableinformatics.com/downloads/all-0.25.tar.gz .  Usage is
quite simple:

[landman at squash.scalableinformatics.com:~/all-1.0]
        69 >./all uptime
        username:
        password:
        ----- machine =crunch:
        .
        .
        .
        .
        crunch: out= 11:03am  up 3 days, 18:03,  4 users,  load average:
0.02, 0.01, 0.00
        ,       error=, exit=0
        ----- machine =squash:
        .
        .
        .
        .
        squash: out= 11:04am  up 8 days, 27 min,  2 users,  load
average: 0.48, 0.43, 0.33
        ,       error=, exit=0
        ----- machine =stuff:
        .
        .
        .
        .
        stuff:  out=blank,      error=blank,    exit=blank
        
        
        -------------------
        
        failed machines=stuff
        
        
(minimal) Documentation included.  No extra daemons required (uses
sshd).

Joe
