What firewall settings must be used on the remote machine for a remote kernel connection to work?
In particular I'm interested in connecting from Windows (front end) to a Linux machine (kernel).
回答1:
I don't know the exact ports, but this is a generic way to solve most such firewall issues: (at least with connections using TCP)
Try to use the 'netstat -n' command and see which remote ports do the connections that are being blocked by the firewall use. They should be in the SYN_SENT state or something similar. Then on the remote machine open those ports and try to repeat this process until it works.
