Unnecessary upgrades
Occasionally I subject myself to unnecessary software upgrades. I guess mainly to see some of the challenges and learn from them, at a non-critical time. I switched my desktop machine to Ubuntu 9.10 alpha (or is it beta) a few days ago. I’m still adjusting, but I’m learning a few things. Today was the pitfalls of IPv6 in a network with old devices. Apparently, 9.10 enables IPv6 by default and my old DSL modem is confused by and unresponsive to the new-style DNS request. Disabling IPv6 (by the kernel parameter method) cleared up my problems with very poor DNS resolution.
