OpenSSH mathlink remote kernel connection problem.
I\'ve installed in my winxp, Mathematica 5.2.0 and cygwin + OpenSSH client (and server). I\'d like to stablish a mathlink connection to a remote Kernel (Mathematica 5.0) on an external machine in a Linux net. I can\'t access the external machine directly from my house (the winxp) via ssh, but I created a SSH-tunnel from my local 11111 port to the remote-machine by-passing the gate server. I also have dsa-key pairs in the right places so I can connect to the Linux net directly without writing a password. Summarizing, I can: -Execute from the command-prompt: "C:\\cygwin\\bin\\ssh.exe\" -p 11111 myusername@localhost math ..and work with mathematica 5.0 in the remote machine. (in the command line, I don\'t worry about the Front End) But I can\'t: -Start the remote Kernel from the front end in my winxp. I\'ve created a Remote Machine Kernel and its \"Kernel Configuration Options..." are: Arguments to MLOpen: -LinkMode Listen -LinkProtocol TCPIP -LinkOptions MLDontInteract And the \"Shell command to Launch Kernel\" "C:\\cygwin\\bin\\ssh.exe\" -p 11111 myusername@localhost \" math -mathlink -LinkMode Connect -LinkProtocol TCPIP -LinkName `linkname` \" After that, I try to execute a simple operation in the remote kernel (say..2+2) and several things happen: -The operation hangs -My winxp , which uses core 2 duo, rise up at 50% in both processors as I can see on the Task Manager, (in the MathKernel.exe process).. -the following process starts in the remote machine: /usr/local/Wolfram/Mathematica/5.0/SysytemFiles/Kernel/Binaries/Linux/MathKe= rnel -mathlink -LinkMode Connect -LinkProtocol TCPIP -LinkName 2250 at 192.168.0.100,2251 at 192.168.0.100 After a few minutes, both processes stop, the notebook stops being hanged but I don't get to know how much 2+2 is... I suspect on the 192.168.0.100 . I use a router and this is my local IP. Why does this number appear? Shouldn\'t be something related to my \"real-IP\"? Thanks in advance for any comment-help.. Atte.
