    Robust sh script to obtain all IPv6 address on an interface?

    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"...

    IPv6 address on WAN interface

    I've been digging into IPv6 lately and have been successful in setting up a working dual-stack network. Altough I'm not pleased with my current setup; that is when it comes down to where the IPv6 address of my gateway box is assigned. I use the isc-dhclient to get a prefix delegation, and rtsold...

    Solved IPv6 client first try

    Dear FreeBSD users, My first IPv6 try with my FreeBSD desktop machine was a bit disappointing. According to FreeBSD Handbook, I added two lines in my /etc/rc.conf: ifconfig_re0_ipv6="inet6 accept_rtadv" rtsold_enable="YES" I added into my fully functional /etc/pf.conf: icmp6_types = "{...

    IPv6 connectivity lost after some time

    Since a few weeks I'm having a problem with the IPv6 connectivity of my FreeBSD 11.0 server. There had been no software updates or configuration changes that I know of that could cause the problem. The server only has IPv6 connectivity (incoming and outgoing) for a short time (approx. 40-80...

    SSH Over IPV6 Possible Bug

    I've been trying to setup ssh exclusively over IPV6 but have run in to a few issues. These are the steps I'm following, theoretically this should just work. Which is why I'm baffled at this point. I researched a few guides going back to version 10.3 and the process seems to be as follows...

    Hi, I am using gif_interfaces for setting up a HE tunnel broker connection. While everything still works I get this warning: /etc/rc.d/netif: WARNING: $gif_interfaces is obsolete. Use $cloned_interfaces instead. However simply renaming it to cloned_interfaces doesn't do the trick. My...

    When will dhclient from FreeBSD base support IPv6?

    Currently, I have to substitute dual-dhclient for dhclient from FreeBSD base to get DHCPv6 addresses, SLAAC addresses, and IPv4 addresses. Amazon EC2 configures dual-dhclient in /etc/rc.conf to support IPv6. It would be ideal for dhclient from FreeBSD base to do the job of dual-dhclient. Is...
