One resource immediately after another
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

Applying changes to route-eth0
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

答复: How to disable CTDB pulling up NICs
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

restarting static-routes-ipv6
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).

xen on openSUSE
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

Need basic PPPoE startup help
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

Emergency help needed on host network randomly stop working.
Hi, This is a Centos 5.5 host with one xen guest. About 2 weeks ago, the host randomly lost network connection. By this I mean I could not connect to the services on it, or ping it. Also was the status of the guest. From serial console, I connected to the host, trying to see what happened. No clue (any error messages) in messages or dmesg. ifdown/ifup the interface did not help, either. Only

Resetting network device / skb leak
hi, I seem to have a problem with the Linux xen-network driver leaking skbs. This is probably my own fault, upon resumption after migration I call this: void network_resume(void) { struct net_device* dev = __dev_get_by_name("eth0"); MOD_DEC_USE_COUNT; network_open(dev); } -- which works fine. However, in network_open() the call to NETOP_RESET_RINGS seems to clear all the

Lingering dhclient issue
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

Unable to get dummy interfaces to persist across reboots in CentOS 8
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

CentOS 7, systemd, NetworkMangler, oh, my
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

答复: 答复: How to disable CTDB pulling up NICs
Thank you very much for reply. Our test team insists on simulating network failure by using ifdown instead of just unpluging the cable. I have to modify the event script 10.interface. When noticing a NIC failure, CTDB just marks the NIC down and do not try to pull it up. It seems to work fine. -----邮件原件----- 发件人: Martin Schwenke [mailto:martin at meltin.net] 发送时间: 2016年9月18日 18:49 收件人: Weidong

C7 and spoofed MAC address
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

kmod-e1000e and Intel Network Card
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:
