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?

Hardware :: Eaton Powerware 9130 - UPS Connection During Lansafe Installation As A Controller And RHEL 5.5

May 26, 2010

We have:

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:

Ubuntu Networking :: 11.04 Management Of Network Card / Wired/wireless Setup?

May 1, 2011

I am facing a problem with the management of my network card after installing Ubuntu 11.04 32-bit Desktop edition.

There are two Network Cards and one USB adapter which I'd like to drive:

- Ethernet controller Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02)
- Ethernet controller Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
- Realtek Semiconductor Corp. RTL8187 Wireless Adapter

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.

Networking :: Gigabit Network Card For CentOS 5.4 Server

Feb 11, 2010

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.

CentOS 5 Server :: What Storage Type To Choose?

Jun 21, 2011

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.

CentOS 5 Server :: Using Winbind With Win2003 R2 AD And Microsoft Identity Management For UNIX For UID/GID Mappings?

Nov 10, 2009

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...

CentOS 5 :: Get The System Booted To A Bare Minimum Required To Install Chef (Server Management Software)?

Aug 20, 2010

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!")

Ubuntu Networking :: Broadcom Corporation NetXtreme BCM5721 Network Card Randomly The Network Connection On The Server Will Stop Working?

Jan 29, 2011

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?

CentOS 5 Networking :: On Board Network Card Refuses To Run Gigabit?

Jun 30, 2009

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.

CentOS 5 Hardware :: Realtek 8169SC Network Card Not Working

May 28, 2010

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.

CentOS 5 Hardware :: 3c2000 Network Card And Kernel Sources?

Jul 24, 2011

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?

OpenSUSE Network :: Network Management Disabled After Start On 11.2

Dec 19, 2009

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)
