I have multiple VPNs, one gives local IP address and another is Now I wish to access machines in 10.2.3.x but Mathematica listens in which is not known for those machines. So I wonder if there's a way to change the default listening up of Mathematica.

For example, if I run

LinkCreate[LinkProtocol -> "TCPIP"]

I get

LinkObject["[email protected],[email protected]",700,12]

But what I actually want is

LinkObject["[email protected],[email protected]",700,12]

I understand this might not be a Mathematica problem but maybe there's a way inside Mathematica. Or maybe I just need to work with my IP routes, but some hints will be much appreciated.

About remote kernels

Thanks to sakra, I found that by simply add LinkHost->"host" in the List of options for LaunchRemote area of remote kernels panel, the default host is set.

Use the undocumented LinkHost option, e.g.:

LinkCreate[LinkProtocol -> "TCPIP", LinkHost -> ""]


LinkObject["[email protected],[email protected]",408,12]
  • $\begingroup$ Thanks!I guessed this option might exist but it's displayed red, so I assumed it's not there. And with this option appended to LaunchRemote, the remote kernels worked fine as well. $\endgroup$
