The Peeing Car IVb—The Return!
Got the car back from the dealership today. The A/C should stop leaking into the passenger side. I hope.
A routing mess
Theoretically, TCP/IP packets don't have to take the same route but
in real life all the packets travel the same path. Do two
traceroutes and you'll see the same path.
But today, something seriously odd is going on with the Telocity network. I noticed some annoying network lags between my home system and my colocated server and did some traceroutes. And I got something I've never seen before: no two traceroutes (done seconds after each other) where the same!

Got to see major network rerouting at work here. From 7 to 19 hops no less! Sheesh!
An FTP mess
Spring has been
having difficulty FTPing to her site. Her computer is currently
sitting behind a firewall, so to use FTP she has to use passive
mode.
But … her web host has stuck the FTP server behind a
firewall, where it doesn't work in passive mode.
So, she can't FTP to her web host.
I wasn't sure how to configure ProFTPD to do FTP proxying, so I
downloaded jftpgw, an FTP proxy. I
wanted it to work in conjunction with ProFTPD, so it took some work (namely,
getting ProFTPD to not bind to every IP address on the firewall, and setting up an extra IP
address for the proxy FTP program to run on.
The contortions one must go through when you only have a single IP address.
The ruling jaunta strikes again
The Condo Commando's still hate Spring's van. This time it's not the fact that the van is covered, but that it's covered and parked in a guest spot! Apparently that's a no-no, even though it isnt' stated in the RULES AND REGULATIONS OF THE XXXXXXXXXXXXXXXXXX CONDOMINIUM ASSOCIATION, INC. AMENDED March 22, 2000.
And I've still yet to sign any papers stating I have read and acknowledge the RULES AND REGULATIONS OF THE XXXXXXXXXXXXXXXXXX CONDOMINIUM ASSOCIATION, INC. AMENDED March 22, 2000 so they can XXXXXXXXXXX.
