I always use CSSH on my Fedora box at work, but this is the first time I have to use it at my home to control my cluster. And my laptop's operating system is Mac OS X 10.8. That is the problem.
Installation of CSSH on Mac OS X seems to be simple. If you want to do it in a lazy way like me, use port.
sudo port install cssh
Then, you try to connect to some host, for example.
cssh root@somehost
It should works well??? Oh no, some strange error message occur like the one as follows.
Can't connect to display `tmp/launch-P6rxkT/org.macosforge.xquartz:0': Invalid argument at /opt/local/lib/perl5/vendor_perl/5.12.4/X11/Protocol.pm line 2270
If you open file Protocol.pm and go to line number 2270, you will see that it try to use INETSocket (wrong) instead of UNIXSocket (right). That is because $host is not equal to "unix". Now you have to change something here to let it use UNIXSocket by checking whether $host contains "xquartz" or not. You change the line number 2262 (the IF command before the error line) from
if ($host eq 'unix') {
to
if ($host eq 'unix' || index($host, "xquartz") != -1) {
(Ahh, that's the error of Perl 5.12.4 distribution of Mac Ports.)
That's all. Let's try again and see everything goes well.

This is the first time I had to use CSSH to operate my cluster at home; normally, I just use it on my Fedora computer at work. And Mac OS X 10.8 is the operating system on my laptop. That's the issue. mexican home decor ideas
