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

What''s going on here? I''m spewing UDP traffic at this thing, and it is exceeding the ceil. Anyone know how to fix this? class htb 1:613 parent 1:5 leaf 613: prio 6 quantum 2560 rate 20480bit ceil 103360bit burst 15Kb/8 mpu 0b overhead 0b cburst 1728b/8 mpu 0b overhead 0b level 0 Sent 16591370 bytes 4159 pkt (dropped 39449, overlimits 0 requeues 0) rate 412384bit 6pps backlog 0b

No. Network Manager is always disabled on our builds since at least Cent5 days. The network stack has always been able to be managed properly without relying on Network Manager. Is that now an absolute requirement? It never has been prior.

A bit more detail. I have the following htb classes set up... class htb 1:356 parent 1:4 leaf 356: prio 4 quantum 1600 rate 12800bit ceil 51680bit burst 15Kb/8 mpu 0b overhead 0b cburst 1663b/8 mpu 0b overhead 0b level 0 class htb 1:357 parent 1:4 leaf 357: prio 4 quantum 1600 rate 12800bit ceil 51680bit burst 15Kb/8 mpu 0b overhead 0b cburst 1663b/8 mpu 0b overhead 0b level 0 class htb 1:2 root

Have you tried to use NetworkManager ? After all ,anything network related should be done by it. [root at system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy ?

I''m using a fairly large number of classes, andf borrowing is not working as expected... I''ve called this setting it up on an IMQ device with speed 1200/256 on a 1536/384 line. I''m then throwing a UDP data transfer at it that gets tossed in one of the class under parent 1:6. The classification is working fine, but when I try to ping out, ping times are in the 900ms

Ok, I did read www.freedesktop.org/software/systemd/man/systemd.unit.html and am still confused. What is it? If it helps, let' suse a real application: I create in /etc/systemd/system/ the home-ducker.{,auto}mount files. Where does this unit file go with respect to them? Is it one of them?

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

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

Hello, I successfully set up a tunnel with tinc using the tun interface. however I need a tap device, because I need to run the OLSR routing protocol on the tunnel and if I use the tun mode OLSR will just skip the interface. (It is a well known thing, I had this issue before also when using OpenVPN in the past). The problem is that I cannot make tinc use a tap device. I created the tap0

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).

Hello, I thinking about using PCI passthrough to dedicated a domU as firewall. I understand PCI passthrough concept. When done, my domU will see network card and the dom0 won''t any more. So I''ll be able to filter all trafic from outside, since it will go through network domU. Then, how will I be able to connect other domU (and maybe dom0) to the network domU ? In a normal way,

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

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a linux system with 4 ethernet interfaces, eth0 goes to the internet, eth1, eth2, and eth3 are NAT''d LANs. I want to use an ingress filter to prioritize bandwidth (downstream from internet) to various IPs. I want to sett it up something like this.... eth0 <--[NAT]--> dummy0 <---> dummy1 <---> eth1,eth2,eth3 dummy1

No i can start qemu but no network I have a bridge br0 with ta0 on it My start line qemu debian.5-0.x86.20100901.qcow --curses -net nic -net tap,ifname=tap0,script=no

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

How does the libvirt deal with the vnet mac address? Greetings, if I establish a network for the VM (hypervisor is KVM) using bridge in the virt-manager , a vnet0 device is created . There are some relationships about mac address between the vnet0 device in the hypervisor and the ethX device in the VM, for example : the mac address of vnet0 is FE:54:00:84:E3:62 the mac address of ethX in the VM

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
