I'm really gratefull for your help! I tried leaving only .bashrc at the master node and I have set the variables as you have suggested, but nothing changed. I've even read again in the man pages about ssh invoked bash, and it realy reads and executes/etc/bash.bashrc file and ~/.bashrc - which ever comes first. I've added echo commands to .bashrc on the master, but nothing is echoed, and ssh node1 'echo $PATH' gives the reduced path again. I'm frustrated. I'm a step away from running OpenFOAM on a LAN over a LiveDVD... :(
