We 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 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 Replies View Relatedwe'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:

Package: <package-name>

View 2 Replies View RelatedI'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.
We are going to deploy a new network with PCs and servers. until here, Windows was choosen. However, because of legacy applications, Linux is now chosen. Therefore, I am looking for something to replace Active Directory. I know there are software for eacho prupose (BIND for DNS, But I would like to have a central tool with integration between services as Active Directory can provide.
The services I need are:
- DHCP
- DNS
- Directory for central authentication (workstations are not on stand alone)
- File shares
- Binary repository for upgrade (as WSUS on Windows)
- NTP
I am looking for a server solution that would allow me to deploy Windows Desktops and software to clients on the network. Ideally I am looking for a Linux server solution but would consider a Windows Open Source alternative.
In the past I have used Symantec Altiris Deployment Server.
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?
Does Linux have any patch management software/solution which can distribute the patches to linux and windows clients

View 3 Replies View RelatedWe (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.
I'm quite new to Linux and totally new to CentOS. I need it to isntall a Lotus Domino Server, and for security reason i'd like to install the Acronis Linux agent to backup this server with my Win Acronis enterprise server. I have installed a new CentOS server 5.4 on a Vmware virtual machine, then installed the Acronis Linux agent following the instruction here [URL].. The agent seems to work because with the command "/etc/init.d/acronis_agent status" the sistem respond with "Acronis Agenti is running"
But i can't connect to the agent from the server console!
I have disabled the firewall to avoid any connectin problem...
Does anybody use acronis with CentOS?
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.
I am trying to monitor server throughput with a centralized ntop instance running as NetFlow aggregator and various NetFlow probes (nProbe, fprobe) on the Servers.ntop shows the probe as NIC correctly and receives the data, but it only shows one Host under "Hosts", which is the server itself. I expected to see a host list just like it is shown when running ntop locally (i.e. the server ntop runs on and every host he contacted separately). This happens both when using nProbe and fprobe. Have I misunderstood the concept of NetFlow Aggregation or am I using ntop/nprobe wrong?
View 1 Replies View Relatedwhat 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 7 Replies View Relatedby now I have 10 servers for hpc, power computing oriented. My users need to launch several processes using qmake. The users are used to work with ubuntu 9.10, and the software from the repositories is switable for them. I've deployed ubuntu 9.10 to all 10 servers (pxe rocks). By now we work with parallel-ssh and cluster-ssh, which allows as to launch the same process to all servers. With this tools this tools the servers remain as independent but with the same software and the same launched command. Now we would like to go to next step and see all the servers as a single one with all the resources from the other 9 as if was its resources. The difference would be substantial in time to process and also time to design the command to launch.
View 13 Replies View RelatedI need to deploy Windows Server 2008 R2 onto a server that is currently running Linux. Effectively, I want to restore a Windows disk image onto the Linux system hard disk.I don't have physical access to the machine, so I need to find a way to do everything remotely, using SSH (no KVM). And the Linux machine only has one hard disk - the one containing the OS. However, I might be able to create a partition in free space at the end of the hard disk to store the image (I might need some help with the Linux commands). Or perhaps the image file can be pulled via FTP.
I tried Acronis but was disappointed to find that it doesn't seem to allow me to overwrite the system partition (unlike the Windows version of Acronis, which is capable of doing this with a restart).
I'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)
Scenario:User1 is always logged onto a Windows client mapped to a Public share on a Linux SMB server.I need a way to keep User1 connected to the Public share and then when needed, allow User1 to provide User2's credentials to connect to a Restricted share.The only way I've been able to do this is to disconnect from the Public Share then reconnect to the Restricted share using User2's credentials. (This is the issue because I need to keep User1 connected to the Public share).Is this a limitation of SMB? Or am I missing a configuration? Please point me in the right direction
create an Apache web server with multiple user accounts, for work. Each user needs to be able to upload his/her files via SSH Each user needs his/her own web directory, (preferably in their home directory for ease with permissions) There web directories need to be password protected Only one user account (mine) should be allowed remote SSH control. It needs to be easy to add new users to the system.
