We use A2 Hosting and have set up our new Mac using their instructions at
https://www.a2hosting.com/kb/developer-corner/version-control-systems1/configuring-subversion
We can successfully connect and check out files using the svn checkout command line, but when we try to checkout the same repository in SmartSVN 9.2.1 it just gives us the "Unable to connect to a repository at URL '-snip-' To better debug SSH connection problems, remove the -q option from 'ssh' in the [tunnels] section of your Subversion configuration file." (there are no -q in our config file, but it always says this.)
When using an older application we used to use on an old computer (svnX) it's a little more verbose in its error. it adds: "Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)."
It gives us this error regardless of whether or not we give it our user name and password, something that SmartSVN hasn't seemed to ask us yet. (we're brand new to this application)
Any help would be appreciated!
