I also note; I think this is (at least partially) due to strongswan leaving a dangling duplicate DNS entry in resolve.conf. It's 100% consistent, that after step #3 above, there is a dangling DNS entry in resolve.conf, and this script hangs. More : 1. fresh boot 2. script checks: - "/usr/lib/avahi/avahi-daemon-check-dns.sh" is fine - "host -t soa local." returns 3. activate strongswan connection = SUCCESS {{{ fermulator@fermmy:~$ sudo /usr/lib/avahi/avahi-daemon-check-dns.sh fermulator@fermmy:~$ LC_ALL=C host -t soa local. Host local. not found: 3(NXDOMAIN) resolv.conf contains: nameserver 192.168.194.20 nameserver 192.168.196.20 nameserver 127.0.0.53 }}} then; 4. disconnect VPN, {{{ resolv.conf dangling: nameserver 192.168.194.20 nameserver 127.0.0.53 }}} 5. script checks: - "/usr/lib/avahi/avahi-daemon-check-dns.sh" HANGS - "host -t soa local." HANGS 6. killall host back to normal; resolv.conf properly only has the local nameserver now (no more dangling DNS), {{{ nameserver 127.0.0.53 }}} 7. script checks: - "/usr/lib/avahi/avahi-daemon-check-dns.sh" works - "host -t soa local." works $ host -t soa local.
