Centos6.4 routing problem
dear All,
I'm facing this routing problem, the setup is actualy part of ltsp, but
I think this problem is Centos-specific.
The server is a Dell Poweredge R210. The install is standard 6.4, updated.
I have one nic facing the public internet:
vi /etc/sysconfig/network-scripts/ifcfg-em1
DEVICE=em1
BOOTPROTO=none
HWADDR=d4:ae:52:c1:28:2b
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet

Set static IP
Hello,
I want my CentOS 6.5 computer to have a static IP. Currently I get the
IP I want because I have my router assign it on the basis of mac address.
I placed the following file as:
/etc/sysconfig/networking-scripts/eth0
DEVICE="eth0"
BOOTPROTO=static
HWADDR=00:1F:D0:9E:AE:67
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
NETMASK=255.255.255.0
IPADDR=192.168.0.99

Bond & Team: RX dropped packets
Hi all,
we are testing CentOS 7 in order to migrate from Scientific Linux 6 /
CentOS 6 and we are facing an issue with the network. Trying to configure
network with teaming in activebackup mode or also with bonding in mode=1
(active backup as well) we see many RX dropped packets in the bond0
interface (around 10% of the total), 100% RX drops in the backup interface
and 0% in the active interface.

After a long break, one more try at bond/bridge nics
took a couple months off due to road blocks, hoping a fresh look would
allow me to use my server as desired.
I have three ports, eth0-2 over two nics.
I want to bond them, and then use a bridge to connect to virtual
machines on the virtual host computer.
Never having done this, I am confused on some parts.
Here is where I am at now and any pointers helpful. Single server,

binding additional IP addresses to centos6 on one interface
I know this was discussed before, and I have seen a million ways of
doing this via online docs. I have a quick question that hopefully the
community can help me out with
I am trying to add a block of 10 IP addresses. Rather then create 10
different alias files, I want to use the RANGE file.
Docs say to use the following format:
IPADDR_START=x.x.x.x
IPADDR_END=x.x.x.x

True bond howto for Centos 6
Hi all,
Read many posts on the subject.
Using 802.3ad.
Few problems;
Cannot ping some hosts on the network, they are all up.
Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts.
Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway.
When cold booting it somewhat works, some hosts are pingable while

IPv6 range provisioning question
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
A few months back, I tried to use the network scripts to provision an IPv6 range
like can be done with IPv4. I was using CentOS 5.2 at the time and was informed
that 5.2 was broken in this regard. I have upgraded to CentOS 5.3 now and I am
trying to get IPv6 to provision an entire range of IPs, but I am still getting
the old behavior and no IPs are

Network card throwing messages I dont understand
I am having an issue where eth1 is throwing some messages and stops
responding. Restarting networking doesn't work and also just bringing down
eth1 with 'ifdown' doesn't fix it. I have never seen anything like these

weakness of helper?
Hi ,
It comes to me that helper has some weaknesses:
1) It is hard to test . No easy way to write test code for it.
(or Just i didn''t know?)
2) Not easy to reuse it on other controller/view/model.
it looks like to that putting the helper code into a model (a
fully helper model , or a mixed model) is good practice.
However i agree that some html intensive

Virtual Box Host Networking problems
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.

resolv.conf rewritten every reboot. How to figure out who and why?
My machine has a static IP, with dhcp and IPv6 disabled. Every time I
reboot, some process rewrites /etc/resolv.conf, including a comment
about dhcpclient. The only package I have installed that shows up in
"rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in
there is named dhcpclient.
I'd like to figure out what software is rewriting this file and why.

bogus bond0 device showing up in /proc/net/dev
I'm running into a situation where a bogus bonded interface named
"bond0" is being created, in addition to the desired "bond2" interface.
Can anyone confirm this? Anyone know why it's happening or what I do
to get rid of it? I wanted to start my numbering scheme at 2 instead of
0, which I didn't think would be a problem.
As you can see, I have no reference

Mixed dom0/domU usage?
Hi,
I'm wondering about the impact of using both dom0 and domU's on a server at
the same time. I'm worried about the performance impact of running a Mysql
server in a domU and now I'm thinking about moving the Mysql part of a LAMP
setup into dom0 and running a few Apache guests as domUs. Since the Apaches
will serve mostly from an NFS share they won't have much impact on
