Symptoms
SSH will fail to start when:
- Normal/Wireguard interfaces only have IPv4 addresses, and
- Extra (e.g., tailscale) interfaces have IPv4 + IPv6 addresses.
In this configuration, the sshd_config file is created with the following information:
Port 22
AddressFamily inet
ListenAddress 192.168.1.66
ListenAddress 100.69.69.16
ListenAddress fd7a:115c:a1e0:ab12:4843:cd96:6245:4510
This is an invalid configuration, since "AddressFamily inet" forces sshd to only accept IPv4 addresses. As a result, the service fails to start.
Fix
The check() function in /etc/rc.d/rc.library.source does not consider "extra" interfaces when setting the values of $ipv4 and $ipv6. It then uses these variables to determine if AddressFamily should be set to inet, inet6, or any.
/etc/rc.d/rc.library.source should either consider extra interfaces when setting the sshd family, or AddressFamily should always be set to any.
