all: I"m just trying to create a simple rsvp session to familiarize myself with the protocol. I don''t ever get a rsvp RESV message only PATH AND PATH TEAR messages. There is a timeout but i''m not sure whats causing it exactly. Can anyone shed some light on why? All the configs and output are below. Please let me know if you need more information. Thanks. Jon Test

Hi, There seems to be a problem with the timer resolution on x86_64. This is clear in ping results - I don't know if it's just a ping problem or if it manifests elsewhere as well. It does also affect mtr and traceroute times. I guess it's more a kernel issue than a CentOS problem, but is anyone else seeing the same? Ping results have a resolution of 10ms - so a ping <10ms

HI, I''m having trouble with a debian etch HVM domU inside a dom0 domu >From domU, I try to ping gateway, but response time change if tcpdump is writing to standard output. Ping without tcpdump running has a 4 ms time. While tcpdump is writing in stdout, in another terminal: # ping -n -c20 10.12.6.1 PING 10.12.6.1 (10.12.6.1) 56(84) bytes of data. 64 bytes from 10.12.6.1: icmp_seq=1

Hi, Greg, Eddie, I found that in SR-IOV + HVM environment, ping latency depends on ping interval. The NIC is Intel 82576 (1000Mbps), server uses xen-4.0.1, domain-0 is kernel-2.6.32 and HVM is kernel-2.6.31. The server and client are connected through a 1000Mbps switch. The data is as following: # ping -i 1 192.168.0.21 PING 192.168.0.21 (192.168.0.21) 56(84) bytes of data. 64 bytes from

Hi! We have encountered a rather weird problem on a machine that we use for our network latency check (smokeping with fping). For an hour (or so) after boot it reports the ping time with a microsecond accuracy (ad it should). Then the millisecond accuracy starts. We have yet to identify the cause and the logs currently do not show anything. Please find an example of a good and a bad result

I just got an inexpensive VPS too have an outside server to play/test with. I am pinging it every 5 minutes and graphing with MRTG on another CentOS box. This works fine to all servers but the VPS. The first ping to the VPS is always crud and following ones are fine. [root at ns1 scripts]# ping X PING X 56(84) bytes of data. 64 bytes from X: icmp_seq=1 ttl=55 time=773 ms 64 bytes from X:

Hi folks, I read quite some posts about "Destination host unreachable" problems before, but none could help me to solve my issue.

Hello @all, thanks for all the helpfull answers in this mailing list. They helped me compiling a new kernel 2.6.10.11 with Xen 2.0.6 (my first one), setting up a dom0 with RAID, LVM and loop devices for domU, integrating a second network as xen-br1 (I''m calling the /etc/xen/scripts/network script from within /etc/init.d/xend to bring up / down the second bridge.) and bootstrapping

Dear all, If I do cause offence by posting OT here I apologise in advance, I am however desperate for help and after posting on other forums without any ideas I know many networking experts will see this here and hope they can enlighten me. I will gladly donate some PayPal money to the person who can help. I have a leased line on 83.111.160.6 (/30 subnet, gw is 83.111.160.5), and they

Hi guys!! This is something that have always bother me, hope you can help me... :) I've 8 server connected using IAX / DUNDi, it works just fine. However, sometimes when some of our links goes down the server takes forever to appear back as OK at DUNDi's list and people can't call the other Box. It's happening right now: CLI> dundi show peers 00:14:22:16:54:c5 200.X.X.6

I am managing two Xen containers which are exhibiting a spooky behavior. There are intermittent network failures that affect only the VM''s, and not dom0. This exhibits itself as problems with nfs locks, snmp, and even icmp ping. The arp tables look normal on both the dom0 and the guest. However, it is definitely arp related. Causing arp traffic of any sort results the problem curing

My Linux workstation (Mandrake 10.1 kernel 2.6.8.1) is dual-homed to two ADSL Internet providers. Card eth0 (192.168.9.250) is the default route and leads to an SMC router (192.168.9.254). Card eth1 (192.168.1.250) leads to a Linksys router (192.168.1.1). I''m not doing any NAT or PPPoE in the workstation - the SMC and Linksys handle it all. If I remove all general default routes from

Hello, I''ve got this problem. There is an linux server with 2.4.24 kernel and pinging from him to internet (or from lan) ping randomly jumps up: 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq=387 ttl=59 time=30.0 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq=388 ttl=59 time=32.6 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq=389 ttl=59 time=34.9 ms

Hi. The configuration script is at the bottom.

Has anyone else noticed with CentOS 5, that ping now starts at icmp_seq 1 instead of 0. It's clearly not a problem, just curious if anyone knows why it changed. Graham
