I know this is strange, but I simply could not get TortoisePlink
to work for me. I bought a new PC and loaded software normally,
including TortoiseSVN. But I could never connect to my (remote)
repository, always getting the error "To better debug SSH connection
problems, remove the -q option from the 'ssh' in [tunnels]."
I tried many variations to remove the -q option; never worked.
A system staff found that if he replaced TortoisePlink with
Putty's Plink.exe, I was able to access my (remote) repositories,
checkout, checkin, etc --- all the functionalities that I used
before my new PC. He thinks that it might be due to a
recent TortoiseSVN release where there was a change in
support for GIT (I no longer remember those details).
