Sure, for w2web you need an URL, but not for ssh. > ssh node is working without password, as is needed. Does it open a new window on your screen or does it stay in the original terminal window ? Your error message indicates that the ssh process wants to open a new window and of course this does not work in a "batch-job". It MUST NOT open a new window, if it does, you have to reconfigure your ssh defaults. can you do: ssh node.chemie.uni-mainz.de hostname or ssh node.chemie.uni-mainz.de "lapw1 lapw1.def" (This is almost what is executed in the parallel scripts. Last tip: check your startup files (.cshrc, .bashrc ,...) to be sure that there is nothing forcing you to have a X-window environment (like a xbiff statement or similar). > > I changed my .machines file to > > 1:node.chemie.uni-mainz.de > 1:node.chemie.uni-mainz.de > granularity:1 > extrafine:1 > lapw0:node.chemie.uni-mainz.de > > when omitting the lapw0:node.chemie.uni-mainz.de in the machines file, lapw0 > is executed and the crash occurs at lapw1, but with another error message in > STDOUT: > Error: Can't open display: localhost:22.0 > Host key verification failed. > cat: No match. > And in the console "X11 connection rejected because of wrong authentication." > appears.
