IPv6 with CenturyLink Fiber
In case you want to know how to configure IPv6 using CenturyLink’s 6rd tunneling service.

It’s been a while since I’ve debuilt anything officially. libffi-platypus-perl libalien-base-perl libalien-ffi-perl libffi-checklib-perl libshell-config-generate-perl libshell-guess-perl The plan is to build a binding to the libgnutls.so.30 API. The certtool CSR (REQ) generation interface does not allow me to create a CRL with “not critical” attributes set on purposes. Maybe […]

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 […]

I am now imaging these partitions to the LVM block devices: calcifer:/home/cjac# for guest in `ls /usr/src/moonunit-guests/ | grep -v -e etc | awk -F- ‘{print $1}’` ; do […]
