Hello all.
Does anybody have experience with pushing CentOS in enterprise?
I have the following situation. I tried to promote CentOS to local bank. They have now a couple of Gentoo-based systems and I tried to explain them that CentOS is much better option for enterprises.
IT department is interested in stability of the system, so they are ready to give CentOS a try. But the problem came from management and information security division.
That guys look much affected by FUD created by M$. They tell the story like "you can not rely on this open source, it is built by just few community geeks, you never know what will happen if the developer will be hit by bus tomorrow" and so on. They especially refer to the last year FUD story published at ZDNet (http://goo.gl/y0LBi) So, IT guys are allowed to use open source only if they can prove that it has stable community and transparent development and build process they can reproduce on their own if necessary.
I guess, I'm not the first who encounter this issue. Could you share your experience how to deal with it? Are there any public resources that can be used as proofs of CentOS stability?

Timo,
Its interesting, I am presently attending a conference in NYC and in one
of the tables I saw the redhat vendor. My first question to them was "
What do you think about centos", they reply "You are using a
distribution without support and that is prompt to failure..." I don't
think this is an accurate statement is it? Anyway to make the story
short, they keep telling how bad centos is for our datacenter and that I
should consider adopting redhat which is more "robust", offers
"virtualization" and nearly real-time support for its customers. I
didn't go the extra mile to ask for pricing but would appreciate your
input about what they said about centos. Lisandro

card is very new and the drivers have not been integrated into the
distributions or kernel. The alternative is to load the driver via
console using any of the modules supply by LSI. Thank you again Timo for
your guidance. Lisandro
You're welcome.
Ah, and welcome to the world of proprietary drivers. This is something
that the OpenBSD guys do right: They ignore them. ;)

Yes, the entire install will be done from a box using this controller and 10 SATA HDDs. Probably will load a mirror from two disks partitions to have some fault tolerance them do the rest of my partitions using LVM. Just having a difficult time loading the LSi driver from the loading process. I wish this can be done from a USB stick since the machine does not have a floppy.

Are you installing CentOS to boot off this controller, yes or no?

Hi all,
Somebody knows how can I bind rsyslogd to a specific ip adress?? I have two
different interfaces on a centos5.5 host and I need to bind rsyslog to only one.
Thanks.

Joseph,
I am sorry but I didn't understood much of your comment, can you brake it down further step by step...I am doing baby steps in centos.

>Can someone guide me on how to load the drivers so the OS can see the controller as it loads.
Download the driver, you get a dd disk for new installs when your root boots off the controller
and an rpm can you use after, and or if the controller is not backing your root.

hello list!
I am attempting to setup haproxy using a shared up I am trying to
setup using the heartbeat package that I currently have installed:
[root@VIRTCENT01:~]#rpm -qa | grep heartbeat | grep -v -e stonith -e pils
heartbeat-2.1.4-11.el5
heartbeat-2.1.4-11.el5
I have /etc/ha/.d authkeys setup this way:
#
auth 2
#1 crc
2 sha1 {SHA}secret
I have /etc/ha.d/resources setup like this:
VIRTCENT01.summitnjhome.com 192.168.1.23
And I have /etc/ha.cf setup like this:
# What UDP port to use for udp or ppp-udp communication?
#
udpport 694
bcast eth0
mcast eth0 225.0.0.1 694 1 0
ucast eth0 192.168.1.200
# What interfaces to heartbeat over?
udp eth0
#
# Facility to use for syslog()/logger (alternative to log/debugfile)
#
logfacility local0
#
# Tell what machines are in the cluster
# node nodename ... -- must match uname -n
node lb1.summitnjhome.com
node lb2.summitnjhome.com
The service seems to start ok:
[root@VIRTCENT01:~]#service heartbeat restart
Stopping High-Availability services:
[ OK ]
Waiting to allow resource takeover to complete:
[ OK ]
Starting High-Availability services:
2010/12/11_22:03:55 INFO: Resource is stopped
[ OK ]
(tho I am unsure of that the INFO notice is of the resource being stopped).
And I have verified that it is running with ps:
[root@VIRTCENT01:~]#ps auxwww | grep heartbeat
root 3646 0.1 4.6 12260 12256 ? SLs 22:03 0:00
heartbeat: master control process

heartbeat: write: bcast eth0
nobody 3650 0.0 2.1 5660 5656 ? SL 22:03 0:00
heartbeat: read: bcast eth0
root 3653 0.0 0.2 61180 736 pts/1 S+ 22:04 0:00 grep heartbeat
And verified that the box is listening on port 694 (the port that I
have set for heartbeat):
[root@VIRTCENT01:~]#netstat -tulpn | grep heartbeat
udp 0 0 0.0.0.0:694 0.0.0.0:*
3649/heartbeat: wri
udp 0 0 0.0.0.0:50550 0.0.0.0:*
3649/heartbeat: wri
However although I have the port enabled in iptables:
-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 694 -j ACCEPT
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT
An nmap scan does not see anything active on 694:

Dear All,
I got a new project to build cloud computing base on centos clustering
(clustering and cluster storage). whether failover, load balancing can
be applied?
I've read about CentOS clustering and cluster storage but I'm still
confused, any help or advice in this thread will be appreciate.
Cheers...
