Hi faassen, Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . Please then run following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux-image-`uname -r` 234484 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message.

[Bug 234484] Re: heavy network activity stalls network (on both ends)
We got bitten by this very bug! I spent a long time making sure it wasn't anything on our network but what clear things up for me was this: copying from Hardy to Hardy works copying from Hardy to Solaris does not copying from Solaris to Solaris works So, obviously it's not the network devices that are wrong. So, I started digging and found a lot of information about stalling issues for scp and large files and the use of scp -vvv to hint at the problem. scp -l works fine if the limit is relatively small. (100Kb/s or so). very annoying. -- heavy network activity stalls network (on both ends) https://bugs.launchpad.net/bugs/234484 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 234484] Re: heavy network activity stalls network (on both ends)
I experience this very annoying bug since several months (after updating from the nice Dapper LTS to Hardy one): I initially suspected a bad network connection at one end but it seems this is not the problem. I also observe that SCP tranfer rates and ETA are false and not updated during the copies... and on very large files (50/100Mbytes), most of the time it finish as "stalled" probably because this timing/counter issue triggers a stop to the scp command. It seems to be a client side problem, not server side... SFTP does not seems concerned (and can be used to finish a long scp stalled file transfer without needing to restart from the beginning). As well, windows XP client scponly does not seems affected and can manage several 100 Mbytes transfers from a hardy openssh server without issues. I found an upstream solved issue that could be related: https://bugzilla.mindrot.org/show_bug.cgi?id=799 The correction should be done in Hardy shipped version because of it's LTS status imo.

I have the same issue. It transfers 2064 kB and then stalls. I can duplicate this with this file over and over and it's always exactly 2064 kB before it stalls. $ scp deps.png lonely:www deps.png 15% 2064KB 647.7KB/s - stalled - If I leave it alone long enough, it will eventually complete the transfer. -- heavy network activity stalls network (on both ends) https://bugs.launchpad.net/bugs/234484 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Dear Ubuntu kernel team, I downloaded kernel 2.6.27 from this URL (nearest one) http://ftp.gui.uva.es/sites/ubuntu.com/ubuntu/pool/main/l/linux/linux-image-2.6.27-1-server_2.6.27-1.2_amd64.deb The results are the same, no luck this time :( Please let me know if I can do anythong else.

Re: [Bug 234484] Re: heavy network activity stalls network (on both ends)
I will try the new kernel as soon as possible, and I will report the results.

[Bug 234484] Re: heavy network activity stalls network (on both ends)
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback. ** Tags added: cft-2.6.27 -- heavy network activity stalls network (on both ends) https://bugs.launchpad.net/bugs/234484 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 234484] Re: heavy network activity stalls network (on both ends)
Possible same issue on upgraded 8.04 and 6.10. When I connect from the same IP subnet all goes OK, but when I pass through a router or firewall the copy is stalled. The rest of network traffic seems to be ok. Tested on different machines all with different gigabit ethernet cards, and with different connections: * Case 1: Standard 64 bit PC w/ Ubuntu 8.04 Desktop and gigabit ethernet connected to a 100 Mbit switch -> gateway (Linux box with IPtables enabled to run as firewall) -> Cisco PIX -> Cisco router -> Destination machine (Sun Fire x2200 w/ Ubuntu 8.04 Server). * Case 2: same as case 1 but destination machine has Ubuntu 6.10. * Case 3: same as case 1 and 2 but destination machine is a Compaq laptop running non-ubuntu Linux. * Case 4: Standard Pentium 4 PC w/ gigabit ethernet card connected to a gigabit switch -> Linksys DSL router -> (public Internet) -> Unknown router -> Standard AMD Opteron PC w/ 100 mbit network card running Ubuntu 8.04 server. I solved the issue adding the "-l" parameter to scp, ranges below the maximum net troughput runs ok, values larger ends to a stalled connection.

[Bug 234484] Re: heavy network activity stalls network (on both ends)
Not really having a clue what I'm looking for, I still tried wireshark (on the Feisty machine while copying to the Hardy machine). Capturing data seems to have the odd effect of making the problem less severe: the large file copy continues while the rest of network isn't completely disrupted, though once every while things do stall. I see a large number of [TCP Out-Of-Order] messages and [TCP Retransmission] messages. I also see a large amount of TCP Dup Ack] being sent back from the Hardy machine. Whether this has anything to do with the problem I do not know. -- heavy network activity stalls network (on both ends) https://bugs.launchpad.net/bugs/234484 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
