DPNS Client Timeouts

From version 1.5.8 onwards, timeouts and retries are implemented at the DPNS client level.

3 environment variables can be used:

  • $DPNS_CONNTIMEOUT -> sets the connect timeout in seconds
  • $DPNS_CONRETRY -> sets the number of retries
  • $DPNS_CONRETRYINT -> sets the retry interval in seconds

The default is to retry for one week.
