I posted a thread on here awhile ago, detailing problems with ClusterSSH and Leopard. I found a solution a few days later, but never posted it. Someone emailed me a couple of days ago so here is the solution for all, enjoy. From either an upgrade or a clean install of Leopard: (If old caches exist from a upgrade, remove from /var/cache) Install All SDK/XCODE 3.0 Tools. After that, from a Terminal: sudo /usr/bin/perl -MCPAN -e shell install CPAN::Bundle (wait too fucking long) force install Tk force install X11::Protocol After that, download clusterssh from http://sourceforge.net/project/showfiles.php?group_id=89139 untar, cd into dir sudo perl -f Makefile This will install it to /usr/local/bin/ WOAH NELLY! Don't run it yet, won't work. You need a few things leopard doesn't install by default that tiger did: An xinitrc, copy the system default from: cp /usr/X11/lib/X11/xinit/xinitrc ~/.xinitrc A bashrc to set ur enviornment variables. Here is mine: source /etc/profile DISPLAY=127.0.0.1:0.0;export DISPLAY Now, you can run X11 and you should see a normal prompt in xterm, not the weird bash 3.21# And just running cssh or whatever works fine. -Neil
