Hello,
you solved my problem, I added the config file so that svn connects to an svn running into an EC2 instance.
Strangely enough, though, in a Mac, with Firefox, Safari or Chrome I see nothing under the line
“To do this, I created this file: ~/.ssh/config and in it I put the following:”, it didn’t matter in my case since just by adding IdentifyFile in the config file it worked.
Thanks and regards,

Pau
