Hello I'm rsyncing files from one machine to another one over internet. I'm rsyncing files from machine B to machine A. Connection is initiated on machine A. The setup is: B---internet---UPC-cable_modem--ddwrt--A, ddwrt does nat A is running current git kernel (from ~2 days ago); IP 193... B is running 2.6.25.4; IP 192.168... ddwrt; IP 89.76... After some time connection stalls and never gets back to working state. I have to stop and start rsync again. tcpdump log shows many duplicate ACKs. tcpdump -w output on machine B: http://carme.pld-linux.org/~arekm/output.transmiter and on A: http://carme.pld-linux.org/~arekm/output.receiver (both dumps have "host second_side_ip" filter set) Could anyone look and try to interpret these? What could be the reason for stalls? Note that my ISP is doing weird things like using 10.0.0.0/8 IPs for routing: 3. 157.25.4.115 0.0% 1 1 0.5 0.5 0.5 0.5 0.0 4. 195.182.218.12 0.0% 1 1 0.6 0.6 0.6 0.6 0.0 5. 10.128.11.17 0.0% 1 1 1.1 1.1 1.1 1.1 0.0 6. 10.139.251.252 0.0% 1 1 6.4 6.4 6.4 6.4 0.0 7. 89.76.22.19 0.0% 1 1 13.7 13.7 13.7 13.7 0.0 (7 is my box doing nat, dd-wrt 0.24) Tried with A connected directly to ISP modem (ISP is UPC cable company) but that didn't change behaviour (I don't have dumps from that though). -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/ -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
