A client has sent me an RHEL 5.1 box for me to do some work on, but it's not registered with Red Hat. This is causing me problems, because it's a minimal installation, and I need some more dev software.My immediate reaction was to install various bits (emacs, and so on) from my Centos 5(.0) DVD.The base RHEL system only had one (disabled) repo entry,so I added a yum DVD repo entry in yum.conf.d.
This looked good to start with, but it doesn't work. Something in RHEL's pirut/yum/rpm/whatever is getting confused, and can't work out what is/isn't installed.
Question - how do you maintain an unregistered RHEL box? Has RH done something to make life difficult? Is my problem simply that I'm using a Centos 5.0 DVD, instead of Centos 5.1? Am I stuck with downloading lots of rpms from the net and doing everything manually? I really don't want to do that.
I am confused to understand the diffrence between SOCK_DGRAM and SOCK_RAW,
1- should i call structure sockaddr_ll for both SOCK_DGRAM and SOCK_RAW?
2- what's the diffrence between these two kind of socket creation:
a) sock = socket(PF_INET , SOCK_RAW , protocol);
b) sock = socket(PF_PACKET , SOCK_RAW, protocol);
I've been using the 64bit version of fedora since release 10. I want to know what exactly makes the diffrence between the 32bit and the 64bit releases. I am having some troubles recently regarding some drivers and other issues in my fedora 12 and I was thinking of moving to the 32bit one,
here are my PC's specs:
CPU C2D Intel 2.6
4 GB RAM
NVidia 8500GT
Nvidia 9500GT
I've managed to use the 32bit apps by installing the 32bit compatibility packages.
I am trying to see if there is an authbind equivalent or authbind package for CentOS/RHEL? x If so, where can I get more info and download it? It seems to be only available for Debian and Ubuntu.
View 3 Replies View RelatedWe are slowly migrating from a predominantly Windows house to a 50/50 Win/RHEL operation and even further in the future.Currently, we have a LOT of Windows folders that are created by custom applications which, upon creation of a new folder set, applies the corresponding ACL so that only the associated groups are able to access the folders. Now for the problem, we are migrating the applications to a RHEL55 environment and it is creating the folders on that system now but the groups are still residing in the Windows AD. Is there an "easy" (I know, a very relative term) to have the Windows groups given permission to the Linux shares without very much manual intervention?

View 3 Replies View RelatedI have been trying all day but so far I am unable to configure yum to use a proxy server to retrieve updates.Due a recent compliance mandate direct internet access had to be removed for a pool of our Cent/RHEL servers. I have added the http_proxy environment variable in /etc/profile using:
export http_proxy=http://ourproxy:8080
export ftp_proxy=http://ourproxy:8080
export gopher_proxy=http://ourproxy:8080
I am using the FQDN of the proxy server, and i can ping that FQDN from the CLI without a problem. When I do this and I reboot the server I can get to the internet through the proxy using links/lynx. Yum however stalls out after loading plugins. I have read in a few places that I need a trailing / after the port number above, adding this and rebooting has no effect.
So I tried specifying the yum.conf file... [URL]. When I do this yum still tries to contact the redhat/cent network directly. No behavior change. If I use tcpdump I can see the server I am running yum on try to directly connect without the proxy, which times out for good reason.
The proxy server I am running is squid, but I can see the server I am running yum on blatantly ignore any proxy settings I have tried so far. I am really in a hole on this one as I have to get several updates to fix vulnerabilities found during our last scan.
In general, how easy is it to convert between CentOS and RHEL (in either direction)?
View 6 Replies View RelatedMy doubt is " Can we install Xen 3.2 on RHEL version 3".
View 1 Replies View RelatedI have a very unusual [and most likely unsupported] upgrade path I need to take.
I have two servers, both Dell PE1800's that I need to upgrade.
One of them is a Fedora Core 4 (x86) box and the second is RHEL5 x86_64.
I need to do an in-place upgrade to CentOS 5.3 without having to reinstall from scratch and keeping my downtime to an absolute minimum. Each of these servers has about 10TB of data stored and I really don't want to have to reformat and restore from backps.
How can I do this?
I wanted to access a SAN partion from my two CentOS 5 servers.

I am currently setting up a Mono environment (mono, monodevelop, gtk#, etc.) in order to experiment with C# programming. Ideally I would like to use the latest version of mono, 2.10; however, F14 repos only carry 2.6.x . Compiling and installing 2.10 from tarballs is causing me dependency troubles which I'm not willing to dedicate much time to. In the meantime, I came across this Novell-hosted rpm repo, which is supposed to be used by RHEL/CentOS users:[URL]. Is it possible to somehow add said repository as an installation source via yum/rpm, or the differences between Fedora and RHEL repositories goes beyond aesthetic differences?

So as the title says, I am looking for your experiences in this issue, because CentOs and RHEL are very, VERY similar, it is basically the same, so I was wondering, if I can get official support from Autodesk if I'll use their software on CentOs instead on RHEL.

Question: Why OS sees eight ways instead of two? Why do extra ways have such strange LUN (16384, 32768, etc.)?
This is actually a question regarding RHEL 5.5. rather than CentOS but I understand they are very similar.With Solaris we use SMF to ensure that certain Java process are continuously running.If SMF notices that Java process has stopped it will run a start script, if we want to stop it, it will run a stop script.What could be use in RHEL?
View 2 Replies View RelatedI have been battling an issue for a couple of days and I have it down to 2 possibilities. Memory or mobo. A server in the DC is being very sketchy. Sometimes it will boot fine, sometimes it will boot but will not show all the memory, and sometimes it will hang before it even posts. I have replaced just about everything inside the system except for the memory and the mobo.
I would like to test the memory before replacing either because both are a few hundred dollars. The problem is, the memory doesn't log any errors and running a memory test with ubcd doesn't work because it's ecc memory. I thought I remembered hearing that there is a way to run a memory test during a Centos or RHEL installation, but I can't figure out how.
The memory is
DDR2 667 FB-DIMM
and the board is

I want to create a small network of 3-5 computers. I want to have one computer as my server and have services like NFS, DHCP, NTP, etc. I want to connect it to 2-4 other clients that have the bare minimal installation of linux on them. I would like 1 client computer to have a static ip address and I would like another to receive a dynamic ip address from the server. How would I go about doing all of this without the assistance of GUI's? I want to be able to do all this with the ks.cfg and network config files.

I just came to know that we can also use HP MC Servicegaurd for clustering in Linux environment too. I did some google but could not found much info about the packages and all. Can I use HP MC Servicegaurd with RHEL/CentOS on 32 Bit Linux on Intel Machines? Is the rpm (or tar ball) of HP MC Servicegaurd freely available? I just wanted to use it for learning purpose.
