Hi

I wish to connect to a remote kernel running Mathematica. I have given
the information in "Basic Options" when adding a new Remote Kernel,
and when I start a calculation such as "Print["test"]" I am asked to
connect via SSH, which succeeds. After that it says:

The kernel Remote_Math failed to connect to the front end. (Error =
MLECONNECT). You should try running the kernel connection outside the
front end.

Do you have any suggestions? The video at the Mathematica website does
not tell me anything I don't already know. The remote kernel is
running Linux (Redhat I think).

Best,
Jim.

Can you post what you have for the Kernel Configuration options - are
you using "Basic" or "Advanced"? Post what you have if you can.

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.
