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

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).

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

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

I recently reconfigured some CentOS 4.3 systems that were using DHCP to use static IP addresses. At the same time, the systems were moved to a new VLAN. Here is the approximate sequence of events that took place: 1. ifdown eth0 2. edit /etc/sysconfig/network-scripts/ifcfg-eth0 with static IP address 3. wait for network folks to reconfigure switch 4. ifup eth0 I may have

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

How about, in your /etc/sysconfig/network file adding or editing the line for IPV6 to be: NETWORKING_IPV6=no and then try a 'service network restart' and see what you get.

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

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

Just wanted to share some success I had moving some Xen guests from one server to another. Problem Recap We had Xen host on a single core 32-bit CentOS 5.4 installation on an AMD Athlon 2.1 GhZ system that was giving hard drive errors and needed to move the LVM-backed Xen images to another server. The replacement server was a quad-core AMD Phenom system running 64-bit CentOS 5.4. Our original

Does Centos 7 use /etc/sysconfig/network or is this replaced by some systemctl set of commands. For example I know to set my host name with: hostnamectl set-hostname nevia.htt-consult.com But I don't know if this is the same as cat <<EOF>/etc/sysconfig/network || exit 1 NETWORKING=yes HOSTNAME=nevia.htt-consult.com EOF

Requirement is a very strong word , but you should consider using it and here is a short demo why: - By default, RHEL uses NetworkManager to configure and manage network connections, and the /usr/sbin/ifup and /usr/sbin/ifdown scripts use NetworkManager to process ifcfg files in the /etc/sysconfig/network-scripts/ directory. [root at system ~]# ls -l /usr/sbin/ifup lrwxrwxrwx. 1 root root 22 21

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 change the host name on a test server, and in the past when I used hostname to change the hostname, it did not seem to change it everywhere. I really don't want to do a rebuild just yet, but I have to feel confident that hostname is really changed (reboot is not too much of an issue). What is the recommened practice? Other than get it right the first time.

What's the right way to assign an IP alias to an ethernet interface that you want to bring up and down manually, not on boot? I tried the old way of making an ifcfg-eth3:0 file and it does work with the ifup, ifdown commands, but even though I specified onboot=no, it activated at boot-up. -- Les Mikesell lesmikesell at gmail.com

Hi, I have CentOS 7 and I am trying to get dhclient hooks working. I have 1) created file /etc/dhcp/dhclient-enp4s0.conf, 2) created directories /etc/dhcp/{dhclient-enter-hooks.d, dhclient-exit-hooks.d}, 3) added line 'DHCLIENTARGS="-nc"' into file ifcfg-enp4s0 and 4) added file /etc/dhcp/dhclient-enter-hooks.d/test with line echo "executed enter-hook", 5) but I was

Odd situation: I've mentioned before that I have several users for whom I have to spoof the MAC address, due to a software license. Now, I've got net.ifnames=0 biosdevname=0 on the grub2 command line, and I've got the spoofed MAC address in /etc/sysconfig/network-sctipts/ifcfg-eth0. But he had a serious problem - X froze, and he thought to reboot, rather than call me. It came up with
