iTerm2 can do it. Create one bookmark per server and set the command for each bookmark to ssh . Then use the 'send input to all tabs' feature. You can open a bunch of bookmarks at once using the bookmarks window (cmd-m). https://iterm2.com/index.html

Just to update everyone, iTerm2 has a new URL :) http://iterm2.com/ – Tmanok Apr 04 '17 at 03:42

https://github.com/peikk0/tmux-cssh is worth trying. Not brew-installable, but it’s just a simple shell script at https://raw.githubusercontent.com/peikk0/tmux-cssh/master/tmux-cssh — so do:

curl -O https://raw.githubusercontent.com/peikk0/tmux-cssh/master/tmux-cssh
chmod 755 tmux-cssh
./tmux-cssh -u user host1 host2 host3 host4 host5

It appears to have been removed from brew `Error: No available formula with the name "tmux-cssh"` – spuder Dec 18 '19 at 17:07

Take a look at ClusterSSH. I have used this to great effect from an OSX 10.5 workstation, but cannot verify that it works correctly from 10.6. I highly suspect it should work fine.

I ended up using csshX:

I think iTerm2 and Command+Shift+I on multiple panes is a better option now. I have tried both. – Ryan Oct 01 '18 at 06:00

There are a number of tools for doing this. One example is Parallel SSH. It looks like you have to compile it from source for macos but it should seve as a good starting point.

This linux.com article has a good description of how pssh works. Also, the comments on that story cover other alternatives like Capistrano. I used to use Tentakel for this purpose but it looks like that project has gone dead.

Note that a lot of the tasks you might want to automate with a parallel ssh tool are really good candidates for automation with a configuration management tool like puppet or chef or cfengine.

ha I think some of us are giving the 'big answer' solutions and some the quick expedient answer solutions. — Phil Hollenback, Jan 12 '11 at 19:15

I think iTerm can do this (iterm.sf.net)

It can't send the same input to all tabs, but not establish the connections automatically, as far as I know. – Pablo Fernandez Jan 12 '11 at 18:40

You could use any number of ssh multiplexers: e.g., dsh (dancer shell), pdsh. Check MacPorts.

Or, perhaps somewhat more simply: for x in $( cat hosts.txt ); do ssh $x ; done

More complicated things, like Chef's knife, Capistrano, func, or helm, also exist.
