Cluster-fork will run a command on all nodes (or a subset). it uses ssh for authentication, and there for should run ssh-agent before doing cluster-forks, ssh's, scps, etc. The complete set of things you will need is: % ssh-agent $SHELL % ssh-add (After you have done the above you can run any number of cluster forks, ssh's etc) % cluster-fork scp frontend-O:<path to file> <path to dest> The scp command is run on each node in the cluster. -p -----Original Message----- From: "Ai Chee Sin" <purplrain85 at hotmail.com> Date: Wed, 20 Oct 2004 14:31:17 To:porterde at mercury.hendrix.edu, gotero at linuxprophet.com, BioBrew-Users at bioinformatics.org, pvfs-users at beowulf-underground.org, npaci-rocks-discussion at sdsc.edu Cc:sinaichee at yahoo.com.sg Subject: [Rocks-Discuss]Cluster-fork command?? Hi, Anyone had any idea how to use 'cluster-fork' command?? Or anywhere online to look for the command? I need to transfer a tar file from frontend node to compute node?? I had tried to connect ftp, but the system return connection refused. I think the system only can used SCP. aichee Nanyang Polytechnic, Singapore _________________________________________________________________ Fast. Clear. Easy.
