Aug 02 06:51:19 <sicelo> thanks sixwheeledbeast. looked at tmo posts, and those are about crashing. mine doesn't crash. but there's something it does that my network doesn't like, or that my network does which  opera doesn't like
Aug 02 06:57:24 <sicelo> but i'll see if blacklisting the other two URLs mentioned on tmo helps
Aug 02 07:16:09 <sicelo> no dice. later when i am free, i should try an http site, and capture all the traffic. :-/
Aug 02 07:22:32 <sicelo> heh, tmo works  though (via https). news.ycombinator.com, m.facebook.com & others don't
Aug 02 07:25:50 <sicelo> one possibility might be IPv6 :-/
Aug 02 07:30:15 <sixwheeledbeast> why v6? opera not compatible
Aug 02 07:33:04 <sicelo> just a random shot. the network provides ipv6 addresses, and even with ssh now, it is slow to connect unless i specify -4
Aug 02 07:33:37 <sicelo> but yeah, opera isn't compatible (i couldn't find anything referencing ipv6 in opera:config)
Aug 02 08:18:32 <sixwheeledbeast> Surely those sites are dual stack tho?
Aug 02 08:20:57 <sixwheeledbeast> Since SixXS closed I have no v6 access for checking.
Aug 02 08:24:13 <sicelo> i will try to disable (or lower the priority) of IPv6 on N900
Aug 02 08:25:23 <sixwheeledbeast> Its a KP thing IIRC
Aug 02 08:25:34 <sicelo> yes
Aug 02 08:27:28 <sixwheeledbeast> Quicker to disable at router?
Aug 02 08:29:45 <sicelo> no. not my router. it's on my work network
Aug 02 08:30:26 <sixwheeledbeast> oh yes you did say it was work, sorry
Aug 02 11:06:56 <sicelo> definitely ipv6. disavled it on /proc, and  sanity restored
Aug 02 11:15:48 <bencoh> huhu
Aug 02 11:45:47 <Vajb> frayed ends of sanity?
Aug 02 12:03:45 <sicelo> meetings can really be boring 
Aug 02 12:24:17 <DocScrutinizer05> sicelo: I had same problem on KDE X86 with FF and kmail TLS POP3 and whatnot. Turned out my ISP broke MaxSegmentSize discovery in the DualStack-lite shit on my v6 cable with local v4 LAN and a stealth 4over6 implementation in the cable modem and the far end corporate grade NAT. So some far ends that offered both IPv4 and IPv6 broke during the SSL/TLS negotiation when packet size seemed to be particularly large and protocol particularly 
Aug 02 12:24:19 <DocScrutinizer05> prone to lockups from segmentation faults and/or paket loss
Aug 02 12:27:11 <DocScrutinizer05> I fixed it in my EdgeRouter8 by setting a 
Aug 02 12:27:14 <DocScrutinizer05> set firewall options mss-clamp mss 1452
Aug 02 12:27:16 <DocScrutinizer05> set firewall options mss-clamp interface-type all

Aug 02 12:29:24 <DocScrutinizer05> the crux:  >>they're filtering ICMP somewhere along the path where the MTU drops, which breaks PMTUD<<
Aug 02 12:44:15 <bencoh> mss-clamp only "fixes" tcp though
Aug 02 14:03:25 <DocScrutinizer05> yoh
