I'm just wondering if there is any fellow sysadmin with the need to execute one command on multiple servers. If so, what technique are you using?
I have grown tired to ssh-ing to 3-5 servers and executing the same thing over and over again, so I'm thinking to make my life easier.
Also, I think I should create keys so I don't have to enter passwords anymore (though I'm using root). After 2 years of doing this, I kind of developed a laziness.
I googled it up, I know about cssh, pssh, tentakel (this one seems cool), and the more pro-genre - Puppet (of which I just heard of, didn't invest the time to read the docs).
BTW, I'm using XP+putty, so if there is any putty-cool-thingy available, that's welcome too. If not, I can always ssh to one server and from there start my rest-of-the-servers-conquest :) *evil*
Hit me up. Thanks.
