I'm using a v6->v4 tunnel broker so my ISP is out the loop, what's more, as I said, > www.python.org also > resolves with an aaaa record (2001:888:2000:d::a2), and I can ping6 > the server, so I know that routing is OK. It looks as if the problem may be related to MTUs. I did a bit of jiggery-pokery with MTUs, setting the MTU for the IF on my desktop system slightly lower than the MTU on the LAN IF of my router, and it appears that the problem is solved for now, at least. I've seen network problems before with MTU issues, especially where UDP packets are involved, as they may be with the tunnel broker. -- Lindsay Haisley | "In an open world, | PGP public key FMP Computer Services | who needs Windows | available at 512-259-1190 | or Gates" | http://pubkeys.fmp.com http://www.fmp.com | |
