Hello all, I've got an issue I'm almost positive is not related to Dovecot, but was wondering whether anyone else has had similar problems or could duplicate my results. Please accept my apologies if this is considered off-topic or this issue is actually just a symptom of my own ignorance. Also, sorry for how long this email got, I knew I wouldn't be able to explain my issue in

Pasi, in http://readlist.com/lists/lists.xensource.com/xen-users/10/50495.html you mention a netback fix without identifying which one. In going over the changes as well as looking at the code, I can''t spot anything related, or see how non-TCP, non-UDP packets could pass checksum_setup(), and hence I don''t really understand how this problem can be considered fixed (for, in the

I have tried to set up app_rxfax to receive faxes over IP. I realise there are mixed stories about how reliable this is at the best of times, but at this point all I'm after is some guidance in interpreting the log below. What does "RTP: Received packet with bad UDP checksum" suggest? Here is the full log: -- Executing SetVar("SIP/0892130888-b27c",

I was just on 70minute call (IAX2 -> Internet -> IAX2) and during that time I heard several "pops", or "clicks". Each time it happened, I saw the following message: Aug 19 15:36:36 NOTICE[1173711792]: rtp.c:429 ast_rtp_read: RTP: Received packet with bad UDP checksum Any ideas what causes these, and why they turn in to a "pop", instead of just silence, or a

We have a customer trying to dial through our server, and our server is throwing tons of these log messages: Jul 27 14:21:02 NOTICE[29210]: rtp.c:431 ast_rtp_read: RTP: Received packet with bad UDP checksum Is it pretty certain, that these are caused by a bad or misconfigured router along the path, or something else network-related? As opposed to the SIP hardware itself? The SIP ATA is the same

Full_Name: Drouilhet R?my Version: 1.8.1 OS: Linux Submission from: (NULL) (195.221.43.136) qchisq(1,10) works well but qchisq(1,10,ncp=0) does not work whereas ncp=0 is the default value of the function qchisq(1,10). (of course, 10 will be replaced by any integer value). Let us notice that this bug occurs only when applying probability one. (qchisq(seq(0,.9,.1),10,ncp=0) works very well).

Hi All, Some more data on this, I've reproduced this on another host that's a completely stock centos/xen deployment with a centos 6.6 domU. Since I?m seeing the retransmissions on the VIF, I don't think it's related to the network stack but just in case.. Each host is connected via LACP with vlan tagging to a pair of stacked cisco 3750's. Host networking config is here:

Hi All, I've tracked this down... We do rate limiting of our vms with a mix of ebtables/tc.

Hello, Just did a fresh install of xen-4.0 and using the 2.6.31.13 dom0 kernel. I have 6 linux debian guests running, and on my host console i am getting these errors rolling pretty constantly. "Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet" I tried doing the ethtool -K eth0 tx off and same thing on peth0, using bridged mode for network config. Any tips?

Hello, my apologies for not being sure whom to tell this problem, but it is very strange. Let me tell the story: I''m using XEN (3.0.2) with SLES10 (x86_64, SunFire X4100). On one machine I have three virtual machines ("DomU") that are very identically configured (SLES10 x86_64 also). There is also a SLES9 (i386) acting as a multi-homed NFS server. I can mount and access a
