In case you want to know how to configure IPv6 using CenturyLink's 6rd tunneling service. There are three files to update with my script: /etc/radvd.conf.header /etc/default/centurylink-6rd /etc/ppp/ip-up.d/centurylink-6rd There are a couple of environment variables in /etc/default/centurylink-6rd that you will want to set. Mine looks like this: LAN_IFACE="ens18,ens21,ens22" HEADER_FILE=/etc/radvd.conf.header The script will configure radvd to advertise v6 routes to a /64 of clients on each of the interfaces delimited by a comma in LAN_IFACE....

Hi friends! I haven't written in a while. I've been caught up in work. But between working, I've put together some new equipment in a couple of new racks. I bought an audio dampened 15U rack a couple of years ago or so, and into it I've placed the RAID array and an HP desktop form-factor ML110 server to drive the disks....

I now have four six-port Qotom systems and one four-port Qotom system in my rack. I have successfully verified that the newest of these is capable of pulling about 745Mbit/s of 1500-byte frames through the switch from six other hosts. I bet it will push data at the same rate. but I can't get iperf to distribute it over the LAG evenly. That's another problem for another day. I know it can handle six large streams at the same time, which is great.

I am recovering some tapes from back in the day that some of you may enjoy. Here is a log of the process so that maybe you can recover some of your own DV tapes. Seems to work well in modern Debian. To attach to the camcorder, I used a PCI-e card that has an old firewire port and some ASIC on board. [ 416 more words ]

A couple years ago, I bought a 12G SAS disk to see if I could get it to work with the RAID controller with external SFF-8088 ports that came with the system I got while I was working at The Linux Foundation. I got an enclosure to go with it because I was enthusiastic and optimistic about my ability to get things all set up. [ 1,083 more word ]
