  • IPv6 Multicast support on libvirt guests using macvtap

    # # Debian / libvirt # # By default, qemu guests network interfaces are created with the # trustGuestRxFilters attribute set to no. This setting blocks # neighbor solicitation and other ipv6 multicast traffic. To enable # neighbor solicitations, modify your interface definition in your # guest definition XML. # For example if you have…

  • Some statistics from the router at the cabin

    sip0 is a GRE tunnel between the router and the colo box in Seattle, the payload of which is encapsulated as ipsec traffic before being transmitted over the Ubiquity equipment to the switch that the CenturyLink DSL modem attaches to. I don’t get centurylink easter eggs in my search results when I use this interface.…

  • Trip Report: UW signing-party

    Dear Debian Users, I met last night with a friend from many years ago and a number of students of cryptography. I was disappointed to see the prevalence of black hat, anti-government hackers at the event. I was hoping that civilized humanity had come to agree that using cryptography for deception, harm to others and…

  • A harowing upgrade

    I just dist-upgraded the blog server to jessie. A couple of errors from code with checks for which modules are enabled from .htaccess (deprecated and now obsolete behavior). Nothing all that rocky. Go team Debian!

  • I just realized how old these name servers are

    I guess I’ve had them around for a while… Maybe I should clean these up… cjac@ns1:~$ ls /lib/modules/ 2.6.18-4-xen-amd64colliertech.fw+0 2.6.32-5-amd64 2.6.24-19-xen 3.2.0-4-amd64 cjac@ns2:~$ ls /lib/modules/ 2.6.18-4-xen-amd64colliertech.fw+0 2.6.24-19-xen 2.6.32-5-amd64 cjac@ns2:~$ sudo rsync -aue ssh ns1:/lib/modules/`uname -r` /lib/modules I remember editing the .config file for that kernel and building it on my first ever 64-bit system back…

  • This is getting serious.

    I might have to visit the HP on which I recently upgraded the iLO firmware… Maybe it would be good if the family visited Seattle. cjac@foxtrot:~$ ps auwx | grep ‘ping ad0.colliertech.o’ cjac 8411 0.0 0.0 10692 920 pts/8 S+ Apr25 0:32 ping ad0.colliertech.org cjac@foxtrot:~$ ping ad0.colliertech.org PING ad0.colliertech.org (208.115.126.68) 56(84) bytes of data. 64…

  • When was the last time you upgraded from squeeze to wheezy?

    Wow. 3G delta. I haven’t booted this laptop for a while… I think I’m finally ready to make the move from gnome2 to gnome3. There are bits that still annoy me, but I think it’s off to a good start. Upgrading perl from 5.10 to 5.14. cjac@calcifer:~$ sudo apt-get dist-upgrade Reading package lists… Done Building…
