I wonder if there is any fast deploy kernel for multiple servers / VPSs when new kernel is available? Kernel from RHE/CentOS is always old comparing to new versions from kernel.org
View 1 RepliesWe have to install centos 5.5 in approx 60 servers and we want to have a server in which we can create an image of 1 server and deploy it on all other severs through pxe. Mainly all servers will be having raid 5 or raid 1 configured. So the utility should be having the raid support.

I want to load the page from the URL: https://88.88.88.88:8888
These should load the files from the main server at /usr/local/pages/ Virtuozzo a OpenVZ panel does it. So how is this going to be possible ? Will DNAT do the trick : iptables -t nat -A PREROUTING -p tcp -d 88.88.88.88 --dport 8888 -i eth0 -j DNAT --to-destination 192.168.0.1:8888
we're about to migrate a set of workstations (ubuntu 10.04 LTS) to a new kerberos/LDAP setup. Basically, this requires the installation of some required deb packages and to copy some new .conf files over the original ones.We made a deb package having these "features":requires the needed other packages as dependenciesbacks up original conf filescopies the new conf files to the right places (i.e. /etc/krb5.conf,/etc/ldap.conf)The problem is: apt-get complains because the deb is "touching" files owned by other packages (kerberos, ldap, etc.). Therefore, the only way to skip this check is either to force apt-get to proceed or using the "replaces" directive in the deb control file, specifying the clashing packages. omething like this:
Code:
Package: <package-name>
Version: 0.9.9

We (like many people) have a QA environment and a production environment consisting of several servers. We want to be able to make sure before we do any yum updates on the production machines that we've tested everything in QA. Unfortunately, yum gets the latest software when you run it, so you could run it two hours apart and up with different releases of some software. We need a solution.
I *think* what I have to do is create my own yum repository. There are a variety of articles on how to do that. But before I go through all that, I wanted to make sure I was on the right track. So the process would probably end up being:
1. Create a fresh repository
2. Upgrade QA from that repository, test, etc.
3. Upgrade production from that repository
Can someone verify this is the correct approach, or is there something easier? It also seems like step 1 is going to take a significant amount of time, plus it will continue to take a significant amount of time every cycle.
So I have a pretty big networking nightmare on my hands right now. Stepped into the dog crap with this one, told my employer that I knew how to setup vmware servers right? Its not hard, install CentOS, install vmware, run the config tool, bridge the network, down the road we all go right? We have 3 servers running about 10 virtual servers.
Here is what we have all together.
CFU <- This is the internet. We have IP ranges xx.18.230 - xx.18.241 Gateway is xx.18.254 and subnet is xx.255.128
DELL PowerConnect 3348 Switch <- This is what everything is pretty much jammed into.
VMH1 <- This machine has 2 NICs
eth0 connects to the DELL switch somewhere on the upper 30+ ports
eth1 connects to the DELL switch on port 1.
It uses firestarter and is the gateway for our internal internet on 192.168.11.XX using IP 11.254. It has 4 vm's on it. One of them is the domain controller, hooked to eth1 using IP xx.11.1. The other one is a server for managing remote backups, it has an external IP linked to eth0 of xx.18.234. The other 2 vm's are for misc remote login stations that use internal ip addresses linked to eth1. It hasn't had a single problem communicating on either one of the ports..
VMH2 <- This server hosts a web server, and some other misc stations.
It hosts a web server on xx.18.230 and xx.18.231
It also hosts 2 workstations on a seperate network, through another router that is wireless....
Now, we have the problem child, VMH3
VMH3 <- This hosts...nothing. It sits and has a ton of storage, but does absolutely nothing, but won't communicate out either one of its network ports.
The xx.36.xx and xx.22.xx networks are there because we have multiple businesses in the building that shouldn't see each other.
what is the best way here? I have like 5 servers, and I want my clients to access each of them, so in case 1 server is down, they can access remaining servers. Also, it will work like user1 chooses the server number and is connecting to a central database, then reply is OK, and he can connect to the server number he wished.
View 1 Replies View RelatedI have a CentOS5 server with dual ethernet adapters + Webmin installed as my Router / Firewall / DHCP server working successfully with 1 static IP from my ISP.

I'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.
I have a CentOS 5.3 box with three network interfaces in it. Each interface is attached to a separate VLAN and I want traffic to stay on each network segment.What I can�t figure out is why I cannot get each interface to have its own gateway and everything gets sent through the default gateway.The basically takes my possible 3Gb total bandwidth and throws it down a single 1Gb pipe.Then on top of that, if I take down the interface (ifdown) that has the current default gateway,I loose contact to the other two interfaces.When I look at the routes, each one of the interfaces shows the gw as 0.0.0.0 and defers to the default route. So I delete the route and try to add a new route with:
[root@testsan ~]# ip route add 10.1.15.0/24 via 10.1.15.1 dev eth2
but end up with the error:
RTNETLINK answers: Network is unreachable
[root@testsan sysconfig]# cat network

I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
I currently have a group of 3 servers connected to a local network. One is a web server, one is a mysql server, the other used for a specific function on my site (calculation of soccer matches!).
Anyway, I have been working on the site a lot lately but it is tedious connecting my USB hard drive to each computer and copying the files. This means I am not backing up as often as I should...
I have a laptop connected to this same network that I use for development so I can SSH into to the computers, is there any software for ubuntu that can take backups of files that I choose on multiple computers? I know I could rsync but is there something with more or an GUI?
Then I can just every 2 days move the most recent backup from my laptop to the USB drive. Then I will have the backup stored in 2 places if things go kaboom somewhere.
I'm running Ubuntu Server 10.04 and have a secure (SSL/TLS) FTP server on it. However, I'd like to use this FTP server to update programs I made using Microsoft Visual Studio. Unfortunately, in Microsoft's infinite wisdom, secure FTP servers cannot be used. Rather than use an insecure FTP server, I want to set up my secure FTP server to be able to access whatever I need to on the machine, and then add an insecure FTP server that only has access to the directory where I put my update files. I am currently using vsftpd as my FTP server. Is there any way that I can set up two FTP servers on this single machine?

I'm running CentOS 5.3 and would like to know what the "best" or "proper" method is to build a custom kernel using the generic kernel sources from kernel.org. Most of the references I've found talk about modifying the current CentOS kernel using the RPM way. I really want to have the latest kernel due to some important security issues that haven't been addressed in the current CentOS 5.3 kernel.
