CentOS 5 Server :: Choose Eaton EX RT 11 Plus Eaton Network Management Card Minislot?
Sep 13, 2010
I have a couple of servers which runs CentOS 5.5 and CentOS 5.4. We have decided to buy a UPS and we choose Eaton EX RT 11 plus eaton network management card minislot. I have read on the site of Eaton that they have two applications which could gracefully shutdown my servers - LanSafe and NetWatch. My experience with UPS and those applications is zero so I`m here for some advises? Do you prefer NetWatch over LanSafe?
1. Intel server board S5500BC 2. Eaton Powerware 9130 connected to server via USB 3. Red Hat Enterprise Linux 5.5 as OS We need to control UPS and server shutdown using Lansafe 6.03.
I was asked a question about UPS connection during Lansafe installation as a controller. My answer was USB. It tried to find UPS automatically, but then showed me the list of available UPSes. I chose my model, changed some characteristics and got among others "connection type: network". Very strange, but can't be changed. At the end i got message "successful installation". But it doesn't work Nor windows installation client can't connect to controller, nor server shutdowns after 5 minutes of energy lost. I tried to find any information about this behavior all yesterday. I even wrote an e-mail to powerware. But didn't find solution
The problem mostly is in text (followed my message) "driver=(none)". It's very strange because usb keyboard and usb mouse are both driver=usbhid. What to do? So, what can be seen in RHEL 5.5:
Actually I need the wireless adapter to connect to the AP, so both of the ethernet card should be disabled. Infact, when I try to access to the AP I must disable the eth0 card by using (sudo ifconfig eth0 down), otherwise the route assigns the default gw (192.168.1.1) to the eth0 device and the network is useless.
I am looking for a gigabit network card for my centos 5.4 server. I am looking for something known to work well with linux. I have been on the bestbuy site and I found a DLink (DGE-530T) card with support for linux from the vendor but after reading feedback from users with that card I am not so sure it is linux friendly. I am now thinking of buying online.
We new have server with VmWare ESXi4.1 and we created virtual machine with CentOS5.6.This CentOS5.6 virtual machine will be used as webserver. We need to backup all files and have access to these files. We are going to keep all websites, databases, backups on data storage (NetApp FAS2000 series).
We have two options to how to use this storage:
1: We can mount storage volume directly to CentOS5.6 by NFS.
2: We can add storage via NFS to VmWare and then add new virtual disks to CentOS5.6 by VmWare vSphere client.
What option would you recommend to use? Which option is better, faster and more secure? My thoughts:If we mount storage volume directly to CentOS5.6 so we can access .snapshot directory there is all snapshots. So it's easy to access all backed up files. NetApp has snapshot system and we can schedule to make snapshots automatically, so we don't need to setup any additional backup utilities in CentOS5.6. But we don't have any NetApp snapshot restoring software license so copy/paste from .snapshot directory is only option.
If we add storage to VmWare firstly (by NFS) and then add new virtual hard disks to CentOS5.6 by VmWare vSphere client so we have to setup rsnapshot(or any similar utility) to make backups in CentOS5.6. But NetApp will also make backups of .vmdk files. So it's like double backups, lol :) If storage crashes so we screwed in both ways, I think.
Many software available for patch managment like OCSinventry, cfengine,puppet,redhat satellite server for linux. I want to perform patch management for my Linux server (centOS, debian) My question is how to find out which patches available for Linux and which patches i need to apply. Is there any way to find out require patches?
can some one advise either on linux or windows, server/network manage software.say each server we can watch the cpu,memory,network card in/out speed, overload etc, any warning.
I have installed Ubuntu Server x64 in a VM (VMWare workstation) but have limited knowledge. Does anyone have steps on installing and configuring NDMP (Network Data Management Protocol) on an Ubuntu server? I would like to set this VM up like a NAS box so I can do some NDMP backup testing.
following situation and configuring authentication for Windows users on my CentOS clients please:IHAC WIN2003 R2 Domaincontroller with ALL my users and groups maintained there. For Usermapping (SID to UID/GID) I want to use IMU which is included with WIN2003 R2 srv and extends my Active Directory schema for UID, GID, NIS Domain etc. I want now authenticate my Windows users on my CentOS clients via their "domainnameusername" and passwords on the CentOS clients.
I also have a NAS server which has usermapping integrated and resolves the Windows SID's to the UID/GID's configured within the IMU schema extensions. Now I have no idea to setup my CentOS clients to use winbind, PAM and LDAP (IMU supports LDAP queries for UID/GID resolving) WITHOUT needing any Samaba Server or functionality.
* Do I need to configure the smb.conf file because my usermapping is done on the NAS Server and I want to resolve my Windows Users/Groups UID/GID's from IMU via LDAP?
* Do I (just) need to Join the AD (2003 native) or even using Kerberos with generating ktpass.exe keytab files (what is needed/recommended and what is the difference?) Can I authenticate the users without using Kerberos?
For e.g. my username is "domainuser_a" and within the IMU the UID is set to "12345", I don't want Samba/winbind to do usermapping again based on the configured values in the smb.conf file. Some hints would be really nice for me to understand how exactly it works and what is needed...
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 am in the process of creating a kickstart configuration file for some RedHat 5.5 and Centos 5.5 servers (Production and test respectively).I have googled about a bit but I cannot find a good list of the bare minimum packages required for a command-line system.If anyone knows how I can trim this list down anymore it would be much appreciated. The aim of this kickstart.cfg is to get the system booted to a bare minimum required to install Chef (Server management software). Chef will then setup Apache, Ruby on rails environment etc.
All this server will need to do is, from a static IP, Host a Ruby on rails app, send emails, send data to a server on the web, accept ssh and occasionally and connect to a SMB/CIFS share This list was taken from the anaconda-ks.cfg file after a RedHat install of what I thought was a pretty minimal system onto a VM but I noticed that cups, the avahi daemonsand gam_server are installed and running which I do not believe are needed for a pure web server.I know that these types of questions are hard to answer without a complete knowledge of the operating environment and what "minimum" is in this case ("@core only? but I wanted yum damnit!")
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?
I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
I can't get wake up on lan (wol) to work on my network card.The strange thing is that before I had it working with the exact same hardware. But I was on Centos 5.4 then. Now I am on Centos 5.5.Am I correct in concluding that the sky2 driver does not support wake up on lan?
I had installed a Centos 5 server, with one network interface card and work find. Now I want to install ADSL (PPPOE) dial-up for internet in this server, so need to add a 2nd network interface card (RTL8139D or other) . After plug the network card, what I need to do in Centos to find this new card and config it?
I've just set up a PC with CentOS 5.3 runing on near identical hardware to an existing 5.2 machine. Motherboard is Asus M2A-VM which I discover by chance generally works very well with CentOS. Ethernet is on board Nvidia.The older machine just did run gigabit speed without any intervention at all, rather to my surprise. The newer machine insists on running at 100 Mbit which is annoying as it is connected to a NAS through a gigabit dumb switch.
The obvious difference between the two is that ethtool on the older machine says that supported ports are TP, and so the port is TP. Whereas the newer machine says that supported ports are TP or MII and insists on running MII. I cannot change this with ethtool -s eth0 port tp. Perhaps not too surprisingly, mii-tool says that the supported speeds range up to 100 Mbit.
I am not very experienced using Linux but I never had big problems with Ubuntu. Now I am busy writing my PhD thesis and therefore I had to install CentOS to use one lousy program that I could not get to work under Ubuntu. However, it seems to be quite fine and it is working well besides one fact: The network card stopped working. In the beginning it was working fine although the speed was only on the level of 100mbit. The switch and the LED on the card indicated gbit connection, though. I tried to install the driver for the 8168 card which reduced the card to 100mbit (indicated by the LED on the switch and the card).
Ethtool indicated it was gbit capable but I couldn't activate it. After reading more and more I figured I have to use the 8169 driver again and live with the 100mbit. Unfortunately, after uninstalling the old driver and reinstalling the driver 8169 the network isn't working at all anymore. The network-manager displays the card as inactive and when I try to turn it on it complains about the wrong mac address, which I am not able to change to the proper one. I am using CentOS 5.5 with the latest updates.
I have just installed CentOS and it is working fine!I made a masquerade with the document there: I didn't used the script, because right now, I do not completely understand it, and obviously I am not modifying anything by leaving it like that.I was using Mandriva before and I am used to graphical tools My questions are:I add the following lines in my iptables:
[root@localhost ~]# service iptables stop [root@localhost ~]# iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE [root@localhost ~]# service iptables save
I am trying to get Centos V 5.5 working on my old P4P800 Asus motherboard . This motherboard has an inbuilt 3c2000 1Gbit NIC. I know from previous experience that it does not work with a standard kernel. So as the network card doesn't work I cannot connect to standard repositories. The Kernel source does not seem to be in the main install DVD so have downloaded [URL].. files from another machine. and loaded them onto the local drive. uname -r reports kernel 2.6.18-194.el5 however there are many kernel src files in the RPMS directory and yum install kernel-2.6.18-194.8.el5 through kernel-2.6.18-194.32.el5 report Nothing to do or incompatible achitechture ? I also notice that make install for the 3c2000 tar file I have doesn't work either. I know Centos is locked down more than the previous Mandrake 9.2 Install was under Mandrake a urpmi kernel-source, make install of the driver code and insmod 3c2000 was all that was needed.I am still pretty new to linux and just need some pointers on what needs to be installed and to identify what centos is looking for?
I tried connect to internet through iPhone (bluetooth tether), so I followed one tutorial... It said I have to change "networkmanager" to "ifup" in yast>network settings, and make some other changes... I did it, but I couldn't connect via iphone... OK... I put back all changes, also changed ifpu to networkmanager.
After reboot, Knetowrkmanager gives me "network management disabled" on startup, instead of list of my networks.
Of course, I google for solution, but without any luck. And then, I don't know why, I killed Knetworkmanager, start it again, and.. it worked!
But now, I have to kill it, and start again always, when I reboot my laptop...(HP Compaq 6720s, BCM4312, KDE 4.3.4)
I have an Asus EeePc 1001PX and on resume I have "Network Management disabled", neither wired nor wireless interface can be configured, the NM icon is greyed out. running ifconfig shows eth0 and wlan0 have disappeared completely.
I found 2 options: 1. https://bugs.launchpad.net/ubuntu/+bug/555571 2. Network management disabled after start on 11.2 - openSUSE Forums
but I don't have the /var/lib/NetworkManager folder at all
I have some problem installing ASM Software (LANDesk) a BMC module on server ACER ALTOS G330MK2 with centos 5.3 totally updated. Could someone help me to understand wich is the problem ?
INFO:Installation is being performed on the RedHat Linux distribution.
DEBUG:distro:RedHat DEBUG:Import of rpm-python code successful INFO:bash is installed with version 3.2
Suppose that it is not convenient to go behind a machine to have a look.So I want to use a command to show whether the cable is plugged into network card. (Media connected or not)Can ifconfig do this? Or another one?
I was extraction some file through command line then I encounter on notification from winrar. This file exist what u want to do replace never quite I don't want that winrar will prompt me to choose action. Everytime whenever this situation occur it will overwrite / skip that file Syntax I am using for unrar rar e -pmypassword filename
I have somehow made 2 internet connections on my fedora 10. one is system default, which doesn't work. so I usually login and select from the top panel to the other working one. how to choose it from a terminal? then I can do it from a remote terminal.
How do I choose a wireless network to connect to? The Ubuntu 8.10 help tells me to open NetworkManager, but the only thing I can find is 'Network Configuration' in System>Preferences. If I try to run NetworkManager in usr/sbin as a root, nothing happens whatsoever. nm-tool lists several available Access Points for my WiFi antenna.
Suppose I have both a hardwired and a wireless network connection active on the same system at the same time. Can I tell my browser which one to use? Can I tell other programs which one to use? Or do they choose for themselves> Or does some automatic system protocol select which one to use for them?
