Re: how to troubleshoot tramp on windows
Paul Gatewood gatewop at onr.navy.mil writes: I actually got this working and am sorry I was so busy I did not follow up my own posting with the results. I seem to have a different problem with plink if I use a non-standard port. Plink expects the port number to be supplied using the -P option. However Tramp uses -p. Is there some way to re-configure this behaviour please?
