Hi all, I have a weird problem. It seems that tcp over pptp can not handle high speeds and connections terminate with no obvious reasons(at least to me). The tcpdump is from 6-STABLE, but I also have a 7-CURRENT machine I can test/try things. I have tried with fetch, konqueror and opera. The results are the same every time, the connection will reset eventually. When I switch my default gateway to a router everything works as expected. mpd doesn't print anything. Any thoughts, suggestions tcpdump readers? example ftp session nik:0:~$ fetch ftp://ftp.belnet.be/mirror/rsync.gentoo.org/gentoo/releases/x86/2006.0/livecd/livecd-i686-installer-2006.0.iso livecd-i686-installer-2006.0.iso 13% of 696 MB 492 kBps 20m52s fetch: transfer timed out fetch: livecd-i686-installer-2006.0.iso appears to be truncated: 100136960/730388480 bytes tcpdump where the reset happens 14:04:24.266162 IP 213.142.144.100.54456 > 193.190.198.20.38723: . ack 53514792 win 32832 <nop,nop,timestamp 178759461 1046845293> 14:04:24.270371 IP 193.190.198.20.38723 > 213.142.144.100.54456: P 53514792:53516160(1368) ack 1 win 49248 <nop,nop,timestamp 1046845294 178759396> 14:04:24.270546 IP 193.190.198.20.38723 > 213.142.144.100.54456: . 53516160:53517528(1368) ack 1 win 49248 <nop,nop,timestamp 1046845294 178759396> 14:04:24.270556 IP 213.142.144.100.54456 > 193.190.198.20.38723: . ack 53517528 win 32148 <nop,nop,timestamp 178759465 1046845294> 14:04:24.270775 IP 193.190.198.20.38723 > 213.142.144.100.54456: P 53517528:53518896(1368) ack 1 win 49248 <nop,nop,timestamp 1046845294 178759396> 14:04:24.270807 IP 213.142.144.100.54456 > 193.190.198.20.38723: . ack 53518896 win 32832 <nop,nop,timestamp 178759465 1046845294> 14:04:24.273327 IP 193.190.198.20.38723 > 213.142.144.100.54456: P 53518896:53520264(1368) ack 1 win 49248 <nop,nop,timestamp 1046845294 178759399> 14:04:24.273454 IP 193.190.198.20.38723 > 213.142.144.100.54456: . 53520264:53521632(1368) ack 1 win 49248 <nop,nop,timestamp 1046845294 178759400> 14:04:24.273465 IP 213.142.144.100.54456 > 193.190.198.20.38723: . ack 53521632 win 32148 <nop,nop,timestamp 178759468 1046845294> 14:04:24.273740 IP 193.190.198.20.38723 > 213.142.144.100.54456: P 53521632:53523000(1368) ack 1 win 49248 <nop,nop,timestamp 1046845294 178759400> 14:04:24.273775 IP 213.142.144.100.54456 > 193.190.198.20.38723: . ack 53523000 win 32832 <nop,nop,timestamp 178759468 1046845294> 14:04:24.274088 IP 213.142.144.100.54456 > 193.190.198.20.38723: R 1:1(0) ack 53523000 win 32832 14:04:24.275729 IP 193.190.198.20.38723 > 213.142.144.100.54456: P 53523000:53524368(1368) ack 1 win 49248 <nop,nop,timestamp 1046845294 178759402> Thanks in advance, Nikos
