Hi, Sadly no suggestions here. I am having the same problem setting up a remote kernel with Linux (on both the local and remote machines.) Searching online I have seen several other similar posts (for example this thread http://groups.google.com/group/comp.soft-sys.math.mathematica/browse_thread/thread/2a7cc4680bd489aa# ), but no solution yet. I have tried basic configuration options, with the machine address set as mymachine.edu and my user name which is the same on the host and remote machines. I have tried editing the kernel configuration to give the path of the program on the remote machine: KernelProgram: /usr/local/bin/math or KernelProgram:/usr/local/bin/MathKernel ssh works between my local machine and the remote machine with an rsa key and passphrase. When I start the remote kernel from the local frontend, I am prompted for my passphrase, and a "top' command of the processes on the remote machine shows a new sshd process which dies immediately. My local machine gets an error of: The kernel linuxkernel failed to connect to the front end. (Error MLECONNECT). You should try running the kernel connection outside the front end. I think someone else in my office was able to run a remote kernel on this same linux machine from a mac, so I suspect that the configuration problem is on the local end. -AG On Aug 11, 3:48 am, Jim Lambaugh <lamba... at gmail.com> wrote: > Hi > > I wish to connect to a remote kernel running Mathematica.
