A Tunnelblick user has reported odd behavior with name resolution failures. I can't tell if it is a bug in OpenVPN, a bug in the documentation, or something else. The behavior is apparently the same in OpenVPN 2.2.1 and 2.3alpha1.
The 2.3 man page says: > --resolv-retry n > If hostname resolve fails for --remote, retry resolve for n seconds > before failing. > Set n to "infinite" to retry indefinitely. > By default, --resolv-retry infinite is enabled. You can disable by > setting n=0. But the behavior seems very different: If a name resolution failure (caused, for example, by losing the network connection) occurs and --resolv-retry is: 1, the first resolution failure terminates the connection; 5, resolution attempts are made dozens of times per second, seemingly forever; or 10, resolution attempts are made every five seconds, seemingly forever. Any ideas if this is a program bug, a documentation bug, or something else, for example, a problem that only occurs on OS X?
