Hello all I am setting up a Centos 6 machine with one network card & one onboard network port. Both are recognized & work. Onboard Network port is unused yet, but is required for dedicated access to LTSP LAN, which would allow older PIII machines to boot from this system. I have installed LTSP but again Networking seems to be the problem area, as the clients won't boot from this

Dear Friends I have 2 netcards (eth0 to Internet and eth1 to internal network) in CENTOS 4.2, bit when I boot system the up eth0 and et1i [OK]. When I run ifconfig the eth1 has not IP configure, then I run command ifdown eth1 and ifup eth1, after eth1 is work perfect. Below I show file /etc/sysconfig/network-scripts/ifcfg-eth1 # Please read /usr/share/doc/initscripts-*/sysconfig.txt # for

I need basic PPPoE startup help. adsl-start DID bring up my PPPoE link (ppp0) to my ISP over eth0 via the DSL modem/bridge. My IPv4 CIDR block is routing and Shorewall is doing the firewalling. But shorewall has to be started after ppp0 is up and working. For now this means running shorewall restart (or start?). Shorewall 4.2 will have a way to restart shorewall without recompiling, I

Hi list It's my first message here, but I use CentOS from long time ago (sorry my language, I'm spanish from Colombia) I have a Intel board with an Integrated Network Card 82578DC. I've sucessfully installed the driver with the RPM kmod-e1000e; I've found it in ElRepo.org, and I've installed it via Yum. After I've installed the package (see this:

Dear Centos-Virt: This is actually a second request for help on the same issue. I finally got to try what several months ago was replayed to me and no joy was to be had. I am afraid the original thread got stale and also had extra, unnecessary data in it. Guest=XP Pro, SP2 Host=CentOS5; # uname -r; 2.6.18-8.1.15.el5 VirtualBox-1.5.0_24069_rhel5-2.i586.rpm

Hi Guys, I want to create multiple virtual interfaces on a system running linux 2.6. The main requirment being, to assign unique MAC address fo each of the virtual interfaces. I need to know, if this is possible and will really appriciate if someone can provide me pointer in this direction. Thanks a lot. R.

Some of the Red Hat Enterprise Linux servers in our environment sometimes get assigned virtual IP addresses (eth0:1, eth0:2, etc). Puppet Dashboard''s parameters seem like an ideal way to define and provision virtual IPs on these servers. One could create a "vip1" parameter on a node, and define a value of the IP address to use for that vip. A manifest could then be written to

I need to apply three resources one immediatelly after another. It''s a ifdown/ifup commands, and command to generate /etc/network/interfaces file. I need to do ifdown, then rebuild interfaces, then ifup. I try to add simple relationship, but in this case some File resources are trying to be applied between ifdown and ifup. So they can''t connect to Puppet master to verify

With one problem down I still have another remaining. Since the installation of our primairy webserver we have had a problem with the network aliasses. Our server has 8 IP adresses so we used the tool provided in the GUI to specify (and name - for our own convinience) eth0 aliasses with the other 7 adresses. After setting them up, applying them, activating them and restarting

I have a series of static routes in route-eth0 Recently I had to made changes and could not find an effective way to get the old routes out and the new routes in. ifdown-route seems to apply the content of route-eth0 to take down the routes listed and ifup-route brings up routes based on route- So what ends up is that the old routes never go away, just new routes added. ifdown eth0; ifup

Got a problem: a user's workstation froze. He wound up rebooting, without calling me in first, so I dunno. But, and this is a show-stopper, when it came up, it came up with the firmware MAC, not the spoofed one. In /etc/sysconfig/network-scripts/ifcg-eth0, I've got the spoofed MAC address, and a UUID. In the grub.conf, I've got net.ifnames=0 biosdevname=0. But when I logged onto his

If eth0 holds virtual IP as its secondary IP and I bring down eth0 by command "ifdown eth0", CTDB will automatically pull eth0 up. Sometime it goes wrong. The virtual IP becomes primary IP, and origin primary IP turns into a secondary IP or just missing. If the origin primary IP is missing, I have to run "ifup eth0" though CTDB has pulled eth0 up. CTDB uses “ip link set eth0

Hi, I have an eth0 interface (it's a CentOS 6 guest VM on a KVM host) which is configured as follows (see below) with a primary public IP address of xxx.xxx.xxx.130 (which works fine). I cannot set an alias IP address. I want eth0 to also use another IP address (xxx.xxx.xxx.131, so I create /etc/sysconfig/network-scripts/ifcfg-eth0:1. Then: # service network restart Shutting down

I''ve been using Puppet now for a month or so and I''ve come to a problem that may warrant an additional Puppet metaparameter. I''m advocating the addition of a metaparameter called "preaction" (or something like that), which will perform some arbitrary action before the resource is modified. There may be a way to do this within Puppet already (with some

My manager tells me a system in the datacenter is down. I go down there, and plug in a monitor-on-a-stick and keyboard. It's up, but no network. I try systemctl restart NetworkManager several times, and ip a shows *no* change. Finally, I do an ifdown, followed by an ifup, and everything's wonderful. My manager thinks that the NM daemon thinks everything's fine, and there've been

I want to change the contents of my /etc/sysconfig/static-routes-ipv6 and NOT restart the network. Is there a way to do this??? I know about ifup and ifdown for interfaces, but what about routing (and IP6 at that).

Arch = x86_64 OS = CentOS-6.4 (centos) with all updates applied to date. On our gateway host eth0 is the WAN access and eth1 is the LAN. I wish to activate the address 192.185.71.1 on eth1. The ifcfg-eth1:192071 file contains this: NAME="" BOOTPROTO=none MACADDR="" IPV6INIT=no DEVICE=eth1:192071 NETMASK=255.255.255.0 MTU="" BROADCAST=192.168.71.255 ONPARENT=no

Dear developers! I''ve found that recent xen releases cannot be simly run on openSUSE! The script /etc/xen/scripts/xen-network-common.sh makes some incorrect assumptions on the SuSE ifup script. Bridged xen networking only works if the script executes this branch: preiftransfer() { true } ifup() { false } ifdown() { false } Otherwise the xen networking scripts fail to put the

Setting up bonding in active-backup mode 1 (using ARP monitoring) on a server, it looked OK, but pulling the active link cable didn't actually work, it didn't fail over. Eventually with manual playing around with modprobe, ifconfig, ifenslave, etc., a solution was stumbled upon: enslave the eth1 device before eth0, and all is good. Why this should matter is a puzzle - I could not find
