Hello Because I did not send , and then retransmitted. I am using the CentOS5.7. In a state where the link down, I did a ping to the IPv4 and IPv6. IPv4 succeeds in ping. but, IPv6 is ping fails. Once confirmed by ifconfig, it did not have a Link-Local Address. At link down, Is the Link-Local Address not set? Leave the link down, Is there a way to avoid this? # ethtool eth1 Settings for eth1: ?

I'm completely confused here and I'm hoping someone here has a setup they're willing to share, or help me configure things on my end. My connectivity is through Comcast, who unfortunately, does not offer ipv6 in my area. My connection goes like this: Comcast -> Motorola Surfboard Cable Router -> CentOS 6.5 server The CentOS server is multi-homed and manages the internal

I can't get IPv6 routing to configure correctly despite everything I've read saying it should This is my network config on a fully-updated CentOS 5.8 system: # cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=my.hostname.com GATEWAY=aaa.bbb.ccc.ddd IPV6_DEFAULTGW=2a02:aaaa.bbbb::1 IPV6_DEFAULTDEV=eth0 # cat /etc/sysconfig/network-scripts/ifcfg-eth0

Hi! I installed CentOS 7 today, it's a minimal install, so it didn't have ifconfig command. So I installed net-tools, however I can't add ipv6 address to it. # ifconfig enp0s3 add fc00::1002/124 SIOCSIFADDR: Permission denied. Yes, I'm running as root. CentOS is running in a Qemu instance with e1000 ethernet card.

Hi ALL, Here is a weird problem comfusing me for a long time. i''v installed xen 4.0.1 with linux kernel 3.1.0-rc9+ Everything works fine except i cannot ping to the gateway in a PVM domU. i''v installed bridge-utils and brctl show like this bridge name bridge id STP enabled interfaces eth0 8000.00219b480d56 no

I''m trying to shape traffic on a Devil-Linux box. This note was originally sent to their maillist, because the LARTC list appears to have been down for the past few days.

Hi all, I''m running some tests with netem and I noticed some strange behaviour that looks like a bug: I''m pinging another machine and adding delay with netem. When I tell netem to give me a 10ms delay, it works fine. The problem is that when I ask for a 11ms delay, it gives me 20ms! It happens for any value between 11ms an 20ms, and it repeats for values over 20ms, now

Hi, My bridging stops when I start a third Xen domain !?!? I have a few domains setup (mail, wiki, pbx). If I start two domains bridge networking works great. But if I start a third, either the new domains does not work or one of the other DomUs stops working! By stop working I mean I can''t route traffic outside of Dom0. I have been looking at this on and off for a couple of weeks.

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 folks, I read quite some posts about "Destination host unreachable" problems before, but none could help me to solve my issue. So here we go: This is what I am using: SUSE Linux Enterprise Desktop 10 SP1 - Current with all updates Network configuration of my dom0: foobar:~ # ip a 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd

Although you can choose this in the installer, isnt the provided values supposed to be the default? I tired the following inst.repo=hd:/dev/sdb1:/repo Result: /dev/sdb1 is not mounted. inst.repo=nfs:[fc00::6009]:/home/auser/repo Result: NFS is not mounted even the correct ip is set by passing ip= parameters. Of course I tested the NFS share using CentOS itself. Thanks for any assistance!

We've been running ipv6 for a year or so now, but some of our newer instances (all on an ESX cluster) are not working. It looks like it's all of our Centos 6 instances. I'm hoping someone can point me in the right direction... tshark indicates that it's neighbor discovery that's failing: <centos666.peak.org> [26] # cat ../network NETWORKING=yes
