hello, i am having problems launching remote kernels. i have a Xeon server (Linux) on which mathematica is installed, and the "math" command works. on my laptop, i have linux too, and on mathematica i add the kernel to be launched on the remote (the server) node. then i try one example: 2+2 i press shift+enter... mathematica asks me to insert the password of the remote node user name.... ok and then i get error message: "The kernel serverKernel failed to connect to the front end. (Error = MLECONNECT). You should try running the kernel connection outside the front end." for debugging purposes, i made a kernel for my same laptop, just like a "Local" kernel but i choose remote and put my ip adress and my useracount of my laptop. i test 2+2, it asks my password..ok, then the same message: "The kernel self failed to connect to the front end. (Error = MLECONNECT). You should try running the kernel connection outside the front end." this is really weird. the parameters of the "self kernel" are this: `java` -jar `mathssh` fcluster@agua math -mathlink -LinkMode Connect - LinkProtocol TCPIP -LinkName "`linkname`" -LinkHost `ipaddress` if remote kernel does not work with my same computer, i better not keep trying with the server yet. any help is welcome, i really dont know what is going on. best regards Cristobal.
