Using Shame and Embarrassment to Promote IPv6
Categories:
Humor
In a previous post I proposed the terms “indoor plumbing” for native IPv6 access and “outdoor plumbing” for tunneled IPv6. I think terminology like this is important. It’s short, clear, and implies an easy-to-visualize hierarchy where anything less than native routing involves uncomfortable exposure to the elements and woodland creatures.
Which leads us to those poor souls with IPv4-only networks.
“Y-you mean to say that you don’t have any modern plumbing at all? (snork) BWAHAHAHAHAHA!”
We could use something similar for unsecured wireless connections.

Polycom IP Phone Boot Analysis
Categories:
Analysis
We use Polycom SoundPoint IP phones here at the CACE Technologies World Domination Secret Lair. While troubleshooting a different problem recently I noticed that the phones do something funny. During the boot process they obtain an IP address via DHCP, similar to most PCs. A DHCP option tells the phones to fetch their configuration and firmware from an FTP server. The funny part is that some of the FTP transfers were failing even though the phones booted up just fine:
SIP firmware download failure
At packet 175 the phone starts to download sip.ld, the SIP firmware image. The transfer starts at packet 177, but the phone cuts the transfer short at packet 181. The phone then behaves as if nothing is wrong. What’s going on here?
