Not made any change at my side recently, yet today I'm getting (intermittent) problems with connectivity to SVN. I was initially getting this with commits, but then thought I'll try a checkout
svn checkout --username=andy_jefferson svn+ssh://email@example.com/p/datanucleus/code/platform/api.jdo/trunk datanucleus-api-jdo-tmp
and I get
svn: E210002: Unable to connect to a repository at URL 'svn+ssh://firstname.lastname@example.org/p/datanucleus/code/platform/api.jdo/trunk'
svn: E210002: To better debug SSH connection problems, remove the -q option from 'ssh' in the [tunnels] section of your Subversion configuration file.
svn: E210002: Network connection closed unexpectedly
i.e it is prompting for "password" (which one???) three times (presumably because it doesn't match whatever it is looking for), and finally for my SF password. I have SF in my SSH known_hosts etc, and the SSH Keys in SF is correct (I use it on other SSH remote logins and works for all of those).
Note that I can do the exact same command above and some times it checks out ok (with no prompt for passwords), and others gives this. Suggests something around authentication??
