CentOS 5 :: Can Redhat Network Be Used For Centos?
Apr 16, 2010
I'm in a research institution with about 20 linux desktops currently running different versions of fedora. The sysadmins used to update and configure each of these machines individually. We want to move to centos to make operating systems more uniform and simplify administration.
The basic needs are: One central, easy-to-use package management for all machines central management of configuration files for all machines. In addition it would be nice to have a local repository with a subset of user-installable rpms. It looks like rhel can do this with the redhat network. Is it possible on centos, too? If yes, is it necessary to pay a subscription to rhn to use their web hosting of services?
Is it possible to list/find/compare the program versions on a Centos system, against Redhat/Centos Errata/Security/Bug lists? Sort of looking for a way to make sure that all the packages on a system are ok, and not a security risk-- Without having to update every package. A pseudo code, in my mind is:
Will Redhat support CentOS under any circumstances? I have heard at my employer that if you setup you system with CentOS and then on down the line you find you need RHEL support that you can purchase a license from Redhat and they will support your CentOS installation.Is that an official policy at Redhat? Unofficial? Or completely untrue?
I just have CentOS installed and cannot get the Agere et131x network card to work.I have tried the following:Reboot the computer and still did not see the network hardware.
I just upgraded from Ubuntu 9.04 64-bit, to CentOS 5.5 64-bit and my RT-73 USB network card doesn't seem to want to function. It always worked fine in Ubuntu by default (plug and play). Is there some setting I need to make to get this working?Even BT-3 (which is quite old) recognizes the RT-73.
I'm running CentOS V5.5. I am intererested in several packages available under RHEL V5. Is it possible to install these directly into CentOS or should I be looking for a package built for CentOS 5 specifically?
i am unable to access internet in linux editions (redhat 5.4 & centos 5.5) recently i have taken a reliance internet connection but the think is i didn't get any ipaddress from reliance, but i accessing internet in window 7 and i have triple boot. pls any one give the solution.
i am using the redhat cluster suite (luci and ricci) on my centos 5.3. i have 2 nodes in a cluster. when i poweroff the first node on wich a vm service is running, the service switchtes to node2. so far, so good :) but when i restart node1 the service is not failback to node1! i have created a failover domain with both nodes and priorized whre node1 has prio1 and node2 has prio2.
how to install redhat 6 beta kernel source rpm under CentOS 5.5? I just download the kernel source rpm-- kernel-2.6.32-19.el6.src.rpm. And I tried run "rpm -i ", it was failure. The error message is "error: unpacking of archive failed on file /home/xliang/rpmbuild/SOURCES/Fedora-KVM-allow-userspace-to-adjust-kvmclock-offset.patch;4bf439e4: cpio: MD5 sum mismatch"
I have added apache application into redhat cluster. If the apache process failed, it will cause the service group fail over. I want to disable the application monitoring. I search throung Internet and it depends on the apache init script. If I change /etc/init.d/httpd status always return 0(success). THe service group will not fail over even apache failed.
However, I want to remain the application monitoring but stop failover. If the application like apache failed, I want Redhat cluster to try restart the application like 3 or 4 times. If restart failed, it will not failover.
If I have Redhat 5 Enterprise workstation, how can I configure it to point to Centos 5 so I can receive updates and fixes through Centos rather than paying for Redhat support ? I heard this can be done, but wasn't sure what the steps are in terms of configuring Redhat
I've been trying to make install apache 2.1.8 and php 5.2.3 and work on them. After updating and installing some dependence files, apache and php could both be installed.
Then I tried to configure them. I added the following content to the end of Apache httpd.conf:
Code:
Then I run /path/to/apachectl start, and saw the message:
Quote:
Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
Then I remembered that I didn't include the rewrite module while making install apache. So I removed the 2 lines I just added to httpd.conf.
But, after running /path/to/apachectl stop and start again, I could still see:
Code:
When I use firefox to open http://host_ip:8080/, I could see "It works!". But when I open http://host_ip:8080/hello.php (the file is already under htdocs), firefox said Quote:
Failed to Connect
Why and how to solve it?
I noticed that for some stupid reason, the conf file wasn't updated at all and the 2 erroneous lines were still there.
Problems with xen 3.1.2 creating and installing domU CentOS 5.5 I am trying to do a virt-install --prompt --paravirt, and the install error out while trying to download install RPMs. I have googled for xen centos virt-install and various permutations. I have found similar howtos for 5.4 and 5.3, but they resulted in the same outcome. I did find several posts with similar issues, but no solution was posted.[URL]..
I am in the process of building a new server on an Asus P5QPL-AM motherboard and an Intel E8600 processor.explain to me the difference between the two versions and what would you recommend.Also, is there any advantage of SATA over IDE hard drives?
I have once tried transferring files from Redhat 9 web files to Centos 5.5 /var/www/html/ directory. Ok... LAMP is installed and working fine. httpd / apache is running and mysqld is installed without root password. Now I wan't to transfer it again to secure the database from Centos 5 to fedora 13. But when I tried browsing the web to check the web files I can only see these:
I have a server that is on both a standard network and a virtual network, as follows: server1 attached to standard network server1 acting as Dom0 with two linux DomU guests (under Xen) I only have one network card. How do I configure server1 to have a different hostname on the standard network than on the virtual network? Here are the relevant network configuration files for server1:
I am attempting to setup a network to network VPN tunnel between our main office and a temporary location. This location need full VPN access back to the main office's network.Anyhow we have spent about 3 solid days attempting to make this work without any great success. Here is our network scheme for these two devices.
Network A (Main Office) (OpenBSD using isakmpd) Network: 172.16.8.0/24 External IP: 1.1.1.1 (obviously not the real IP)[code].....
I have installation of Xen and Centos 5 (all RPMs are from Centos repositories). I have several DomU virtual machines running on this machine. When I try to copy some bigger amount of data from another physical computer to Dom0/DomU on this machine, the network freezes. The link is still up, I can see that the connection really links on the switch, but nothing is received or sent to the network. I tried to stop all the DomUs, stop the network, unload the network drivers from memory and loading them again and starting the network, but the problem persists. Only reboot solves the problem. Sometimes the amount of data have to be around gigabytes (last time it was 10GB), sometimes 500MB is enough to stop the network... I also tried to change the NIC, but the behavior is the same. Btw. logs don't say anything :-/
PS: this is the output of my lspci:
00:00.0 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge 00:00.1 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge 00:00.2 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge 00:00.3 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge
I have installed CentOS 5.6 X64 on my laptop ASSUS. I can't configure ethernet card. I saw the card listed in the lspci but not under ifconfig -a. From dmesg we can see that the driver is loaded.
I intent to develop a centos server with lamp. What I want is connect the server to any kind of home network and access it by hxxp://myserver.
If you had to develop a solution with the intent to plug in the box by Ethernet to a router and access it with a browser using the server name what would you do? That's basically what I'd like to know.
I try to install CentOS 5.3 with DVD. After choosing option for disk format, next step should have been Network configuration (for dynamic or static) but I found no thing. I chech many times but still can not find any steps so that I can configure network before anaconda starts to install CentOS. Note that, I choose option to install from dvd not via network.
I have two CentOS 5.4. One is real/host and the other one in VMware-Server.
IP of host is 192.168.200.0/24 and IP of guest is 192.168.210.0/24
I can use ftp,samba,http .. between them but can't mount nfs in the guest and vice-versa since, they are in different network. showmount -e , shows the nfs shared list
For several months I've been running a Centos 5.3 server on a home network. The server hosts PHP, Postgres and lighttpd and other open source software bundle into a system I call RIMS. PHP, Postgres and lighttpd and other open source software were compiled from tar files. All Windows machines on the network can access RIMS via lighttpd. No special firewall rules are required on the PCs or on the 5.3 server.
With the release of Centos 5.4 I decided to do a major upgrade to MJR and built a new 5.4 server using a minimal install from CD1, with all options deselected. The details of the installation are available at http://pastebin.centos.org/31877. I added gcc, gcc-c++, m4, make, mlocate and vixie-cron using yum, to give me a compiler and a search capability on the new server.
Problem: when I compile and start lighttpd (or nginx or httpd) on the new server none of the Windows PC can connect to the server - they time out waiting for a connection. I didn't discover this until I'd installed a lot of open source software on the server, so I went back and rebuilt the server with only lighttpd on it, but the problem persists.
I thought it might be a firewall or Selinux problem so I compared the Selinux variables on the 5.3 server with those on the 5.4 server and they are basically the same. Setting httpd_can_network_connect on doesn't make any difference. I also compared the iptables script on both servers and they are the same. I've run nmap on the 5.4 server and it shows port 80 is open. The list of installed packages on the 5.4 server is available at [URL]...
I have centos 5.4 with kernel 2.6.18-164.el5, i want know what card for 100mbit or better connection is good solution, some hints for network card? What do u think about this cards?Intel Gigabit CT Desktop bulk - EXPI9301CTBLK or something different for game server?
