Re: Any changes in kernels the last month (Iptables related)
Hi all kernel 3.2.0-68 solved it, i now have 17-18mbit upload on LAN (on WLAN, still need to tune a bit then... too slow) Kind regards Kim On Fri, Sep 5, 2014 at 6:54 PM, Joseph Salisbury < joseph.salisb...@canonical.com> wrote: > On 09/05/2014 12:44 PM, Doug Smythies wrote: > > On 2014.09.05 09:22 Joseph Salisbury wrote: > > > >> On 09/05/2014 09:58 AM, Doug Smythies wrote: > >>> On 2014.09.05 01:10 Kim Emax wrote: > >>> > >>> ... > >>> Anyway, and in my case, the issue is resolved in the next kernel, or > by going back to the previous kernel. > >>> > >>> Linux doug-64 3.2.0-68-generic #102-Ubuntu SMP Tue Aug 12 22:02:15 UTC > >>> 2014 x86_64 x86_64 x86_64 GNU/Linux > >>> > >> Hi Doug, > >> > >> When you say it was resolved by going to the next kernel, do you mean > >> you apply the latest updates and the next kernel is what came in with > that(3.2.0-68)? > > Yes. > > > >> Or do you mean the next kernel that is in the next Ubuntu release like > Trusty or Utopic. > > No. > > > >> Does the bug exists in 3.2.0-67 but not 3.2.0-68? > > Yes. > > > > Sorry, for my lack of clarity. > > And also, when I said "or by going back to the previous kernel", > > I should have said the previous kernel that I had, as I missed a couple. > > So that was 3.2.0-60.91 > > > > My issue seems to have been that bug report that Hirotaka Yamamoto > pointed to earlier. > > > > ...

Any changes in kernels the last month (Iptables related)
Hello I was wondering if there´s been any changed in the later kernels? I´m using a ubuntu server with tow nics as a router, firewall, DHCP etc. The last month out of nowhere and without any changes (other than regular updates from apt) my LAN has been fucked on upload (0.07mbit), while the WAN has +40Mbit. I´ve rebooted switches and WLAN router, changed the LAN nic and has a laptop directly to the router, no luck. By changing in the iptables rules i´ve managed to tweak the LAN upload to 1-2mbit, still works really bad on LAN though. Taking a test at hastighedstest.tdc.dk shows NO speed at first, then after a while it goes up a bit up to 3mbit, then falls back and stays around 1mbit. Wierd behaviour. Current Kernel: 3.2.0-67-generic, Ubuntu 12.04 -- Take care Kim Emax http://emax.dk -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
