Using Puppet to swap eth0 and eth1
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

Recommendations for Infiniband with CentOS 6.7
We have a new install of CentOS 6.7 with infiniband support installed.
We can see the card in hardware and we can see the mlx4 drivers loaded
in the kernel but cannot see the card as an ethernet interface, using
ifconfig -a. Can you recommend an install procedure to see this as an
ethernet interface?
Thanks

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

Simple IP Question
I have a server located remotely running CentOS 5.x. I need to have
two IP's on the same interface. So I have this:

Disabling IPv4
I want to seriously work with IPv6 and not have stray IPv4 functions
messing with me.
So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have
NETWORKING_IPV6=yes.
In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting
BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on
it (have IPV6INIT=yes and IPV6_AUTOCONF=yes).
But lo had IPv4. So I commented

A bridge problem
We just went to replace the bridge/firewall services one one server with
the same on another. It's pretty simple, and I literally cloned (w/ rsync)
a third server that does this onto the one that will be the new one. Then
copied the /etc/sysconfig/iptables from the one being replaced, and
brought it up this morning.
Nope. We had to put everything back the way it was.

virtual interfaces
I have CentOS 4 running on an old (early model) p3 with 64 MB RAM. It
is acting as a router and firewall for my LAN.
CentOS is doing a really good job with Shorewall + DHCPd - on a 10 Mbps
cable modem, I see ~ 9.7 Mbps of throughput even when numerous tcp
streams to different LAN hosts are running.
I would like to add a virtual interface to one of my LAN interfaces.

Dashboard parameters to control VIPs?
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

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

Broadcom NIC Binding under Centos 4.2
Hello all,
I'm having unusual difficulty configuring teaming with Centos 4.2.
The 2 NIC's are Broadcom. The HW is HP DL360 and there is no teaming
driver for RHEL4 since it comes with package (says HP).
Since there is no teaming driver from centos (as far as I know), I tried
the Broadcom Driver, configured the team file, but the team just wont
come up. A Virtual Interface should be up

CentOS 5.7 Ethernet bonding - order of enslavement matters?
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
