Okay, so I''m trying to setup my multiple ISP setup that I described earlier. I have: # ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP>

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the

CentOS 6.2......... Why do the physical interfaces report (correctly) that they're negotiated at 1000Mb/s, but when I `cat /proc/net/bonding/bond0` I get 100Mbps for the member interfaces, and when I ` mii-tool bond0` I get 10Mbps for the bond? ----------------------------------------------------------------------------------------- ethtool em1 Settings for em1: Supported ports: [

hello all, I have been trying to set-up bridged network with VLAN and not able to succeed as many tutorials address only single NIC. I am trying to setup 2 guests (backtrack instance) each guest has NIC1 and NIC2. following is snippet for guest1 I am not able to get 192.168.0.2 address back on guest eth0.

I have an Intel X540 SR-IOV NIC in a box with ACS support running RHEL6.4. Hi Hongming, I'm hoping you can please help with two issues: 1. The pool works, but I transparent VLAN with the pool does not. I have to manually run "ip" afterwards to get it to work. # virsh net-dumpxml em2net <network connections='1'> <name>em2net</name>

Hi all, Someone played with kickstart bonding with centos 6.4 ? CentOS 6.4, as upstream now support ifcae bonding in kickstart network section. I've an issue with configuring a second bonding iface in kicstart on CentOS 6.4. The first bonding (bond0) works as espected but the second is not configured during installation. I've a 6 nic server (two for "puclic" network, two for

hi everyone I'm having a bit of a puzzle on one centos system, I have four interfaces: nm-team1 10.5.6.100 em1 192.168.2.17 em2 192.168.2.18 p3p3 172.25.12.222 I do: ping 10.5.6.17 -I em1 PING 10.5.6.17 (10.5.6.17) from 192.168.2.17 em1: 56(84) bytes of data. 64 bytes from 10.5.6.17: icmp_seq=1 ttl=64 time=0.367 ms the same for -I em2, for -I em1 and naturally for -I nm-team1 - all good.

I think I just saw a thread go by on " how do I make interactive PDF from rgl output" but I ignored it at the time and can't seem to find consensus result on google. Essentially I wanted to create pdf or other output to share a 3D plot and let viewers interact with it but it still wasn't clear on easiest way to do this. Is this 2009 page the best reference?

I have a second server and gave it a WAN address and I can connect between them using their WAN addresses. That's what told me that my ip6tables weren't screwed up and that the problem lay elsewhere.

I just got 50 Mbps symmetric fiber from AT&T and it includes a /56 of IPv6 addresses, replacing a much slower ADSL line. I never tried to get IPv6 working on the old connection. I'm using CentOS 7 as a gateway and it's worked great for several versions for IPv4. I'm not seeing any IPv6 default route on the WAN interface. I suspect I'm not getting route announcements. I

Hello everybody Unfortunately my problem still doesn't have any solution. But I have an interesting observation. The gateway freezes very quickly, if torrent client programs are running on workstations. I assume the cause of the problem consists in many number of TCP/IP connections that torrent client establishes. Any ideas? Maybe I can tune somehow a TCP/IP via kernel, sysctl or pf settings?

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

If I'm using the SR-IOV Pool assignment method (from http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition ), how would I check how many virtual functions are already in use? Is there a method other then looping through all the active guests and determining if they're using the SR-IOV interface?

Just installed centos 6.2. I run and ifconfig -a I see and em1 em2 and lo interface. If I go to /etc/sysconfig/network-scripts, I don't see an ifcfg-eth0. If I run ifup eth0 it comes back with "Device eth0 does not seem to be present, delaying initialization". Anybody have a clue? Thanks in advance.

Hello I have a virtual server with 3 existing VMs running on it without issue. The host has 4 NICs installed; em1 for the host, em2 and em3 already in use by other VMs. I would like to dedicate em4 to my new VM however when I create the bridge like I did for the others I do not get a vnet3 device show up in the list as shown below. I tried using the GUI and virsh to create the bridge. I ended

Starting back in RHEL/Cent 5 I found that the only way to make sure your interface enumeration was consistent after install with what you had during install was to create a udev rules file using the mac addresses as the key. It is easy to run a short script in postinstall to create it based on how anaconda has seen them. In order for this to work on Cent 6 you have to set biosdevname=0
