    net-mgmt/netbox: configure as a directory service (not vhost)

    Port net-mgmt/netbox is a nice tool widely used for IPAM and DECIM maintenance, so I tried to use it for maintenance purposes at work. I never got past the setup, since the example shown in FreeBSD's wiki (https://wiki.freebsd.org/Ports/net-mgmt/netbox) only covers a setup as vhost, which...

    Sendmail access.db and IPv6 prefixes

    Hi all, I need to specify an IPv6 prefix in /etc/mail/access using CIDR notation and it doesn't seem to work (nor can I find it documented). My range is similar to: "2001:DB8:1111:2200::/56". My network doesn't fall on a 16 bit boundary so I can't just specify "2001:DB8:1111:22" as this is...

    Hello, I have some jails on my FreeBSD host. They have IPv4 addresses on a cloned interface lo2 I created. None of the jails has an ip address on the external interface of the host.

    I am experiencing this odd issue when I restart one of my jails, which operates as the IPv6 router, does not respond to IPv6 packets, even though tcpdump reveals that it receives them.

    While ipfw supplies me6, I need the list of IPv6 addresses for a specific interface to be used in an ipfw ruleset. "Screen scraping" ifconfig is one option, but having a firewall at the whim of the human-readable output of even ifconfig is concerning. Is there a better way with the "stock"...
