NetBSD 9.4 is out.

I ran four tests yesterday using iperf3. The T6225-CR NIC still runs with Chelsio’s SM10G-SR optics. It’s amazing that receiving TCP streams runs at full speed. Sending TCP streams limps away only at a few megabits per second. This wasn’t expected at all. Even IPv6 runs faster than IPv4 for these particular tests. The Cisco […]

AFRINIC with only two years to go
According to Geoff Huston‘s automated predictions, today is the day where AFRINIC has only two years left before they run out of IPv4 addresses. As time progresses, AFRINIC might hit their Z day sooner. AFRINIC has a webpage of their own on the IPv4 exhaustion within AFRINIC.

Sometime ago I switched from a Huawei E220 to a Huawei B593s-22. My 3G internet connection became a 4G internet connection in an instant. I recently turned on IPv6 on the 4G WAN interface, only to be really disappointed. NetCom does not offer IPv6 service to its 4G customers. That’s a shame. With ARIN running […]

ARIN announced today the depletion of its IPv4 resources from their free pool. Only AfriNIC remains before all public IPv4 addresses are depleted. IPv6, anyone?

ARIN, the American Registry for Internet Numbers, is closing in on their Z day. Soon only AfriNIC will have IPv4 address blocks available for their customers, and even AfriNIC will run out of IPv4 addresses sometime in the year 2019. See ARIN’s IPv4 depletion webpage for more information. The bottom line is: Start using IPv6!

Finally, a CygWin package for mosh 1.2.5 is available. Run to your nearest CygWin mirror and update your system. If you’re new to CygWin, I advise you to select mosh, Perl, and OpenSSH, in addition to the base set of packages selected for you.

I had a FreeBSD setup I wanted to replicate to another, identical computer. The source system runs ZFS and so should the receiving system. A recursive snapshot in combination with the zfs send and zfs receive commands proved most fruitful.

Today at work, we received an ATEN/ALTUSEN KN2132 KVM switch. Unlike our previous KVM switch, this model has IPv6 capability. Sadly, version 1.8.174 of the firmware contains an annoying bug. If you want to use SLAAC, then the firmware neglects to invert the universal/local bit while transforming the MAC-48 address to a modified EUI-64 format […]

I tried FreeBSD base/head with only an IPv6 address configured on the NIC. While installing some ports, I soon ran into the problem of living in more or less total isolation.
