Hello list, I install the tinc 1.0.33 through Homebrew using the below command: brew install tinc And I configure the tinc and want to start it, but the tinc logs shows that utun socket resource busy: /u/l/C/t/1.0.33 ❯❯❯ cat /usr/local/Cellar/tinc/1.0.33/logs/tincd.log 2018-02-26 16:04:15 tinc[60361]: tincd 1.0.33 starting, debug level 0 2018-02-26 16:04:15 tinc[60361]: Could not connect utun socket: Resource busy 2018-02-26 16:04:15 tinc[60361]: Terminating /u/l/C/t/1.0.33 ❯❯❯ If I use the tuntap module, tinc works well, but the built in utun fails. The tinc documents says that tinc supports macOS built in utun interface. Does I configure some else wrong ? Below are my configuration and logs files. -- All the best! http://luolee.me -------------- next part -------------- An HTML attachment was scrubbed...
