I have a Cisco 6509 switch that I'm monitoring with SNMP from a CentOS5 machine. SNMP polls are the only access I have to this device, we are not allowed to log on via telnet. How can I find out which port on the switch a particular server is connected to? I was hoping that this is somehow possible using the mac address and the data gathered from snmpwalk/snmpget requests but I'm not

Hi *! I have to install a xen virtualization host that will start with 4GB RAM and will maybe grow to 8GB in the future. And there has to be a 32bit winXP domU. Is CentOS5(.1) x86_64 able to run 32bit HVMs or do i have to stick with i386/PAE? /nils.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a problem with a couple of my centos servers hitting a kernel panic about once a week or so. I find them sitting at a panic screen like this: http://img228.imageshack.us/img228/1044/screenshotoakpanicma4.jpg (58k) Two questions: 1) How do I make it reboot after a panic instead of sitting in a hung state? 2) How do I turn on logging so

Hi, I have a CentOS 5.0 LAMP server, and I need to install the php-yaz module to implement the Z39.50 protocol (which handles data exchange for public libraries). I've already done this with Debian (a one-liner: apt-get install php-yaz) and also on Slackware (more complicated: compile Yaz, rebuild PHP). Has anyone here ever done this on CentOS? What would be the most orthodox method to

Anyone played with or know the status of Red Hat Directory Server on CentOS 5? I had some problems getting this to work on CentOS 4.4, but am very interested in using this instead of regular OpenLDAP as it supports two way synchronization to Active Directory. Noah

Hello all: Is there a network switch that will give me traffic stats at an IP address level? Right now, I only get statstics at a port level, but that does not help since each of my servers run several virtual machines and I need to measure traffic per virtual machine.

Hi, I think about buying a NAS-server from Sun. To backup this server I want to use our central to-tape backup. For whatever reason ppl are asking me to make one compressed copy to disk and only backup this copy. So to reduce load I'd like to have a script that: identifies changed files only (using md5?) copies them and compresses them storeBackup.pl does something similar, but keeps

Hi list, I run quite a few centos 5.3 servers and have a local yum repository which is working fine. Below a list of what I'm rsyncing at the moment + an extract from my / etc/yum.repos.d/CentOS-Base.repo file I copied the OS directory from the install media and ran createrepo on that dir. I would like to upgrade my servers to 5.4. I was wondering if I could simply replace the

Hello List, I need storage for my home network - lots of storage. It's going to hold pictures, home movies, music, other bits of data, etc. I'm looking to start at about 500 GB, but I'd need to eventually grow that to 1 TB, or more. I also want something that is quiet, has hot swappable drives (not necessary, but a plus), is fairly easy to manage, and can be directly attached to

hi, we've a few 10-20 server in a lan each has 4-8 hdd. we'd like to create one big file server on these server hard disks and we'd like to create it in a redundant way ie: - if one (or more) of the hdd or server fails the whole filesystem still usable and consistent. - any server in this farm can see the same storage/filesystem. it's someting a big network raid5-6... storage where

Hi, I have a centos 4 box i use for a file server (nfs and samba). It has two hdd: hda is for the standard install; hdb is for /export/samba/netdisk0 hda is lost - it just clicks now i think hdb is still good i can't figure out how i can remount the hdb disk in a new machine and retrieve the info from it; i've scanned the LVM howto and googled some LVM topics, but nothing seems to

Hi All, For quite some time I've used raid 1 as a means of providing a rollback mechanism for an upgrade (which I learned from others long ago). So essentially, before an upgrade you split the mirrors and upgrade one side or the other. If your upgrade goes well you sync one way, if your upgrade does not you sync the other (much hand waving and chanting going on, as its more complicated than

Hi, I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done it). On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it. Has anybody done this on a cLVM PV ? I'm trying to rescan the devices, but I can't "see" the new size. And, googling on it I can only find RHEL5.2 responses. Thanks in advance,

Does anyone know about some free (as in beer, and maybe as in speech) software which would implement authentication and authorization of a user prior to issuing a valid dhcp lease? I imagine the following scenario: someone walks into my office building with a laptop (a colleague, a visitor, a guest, whoever), and hooks up onto the local net (wired or wireless). The server detects an unknown

Hi, I'm searching for "virtualization options". I already take a look on VMware, but it needs too much MS software to work for my needs. Citrix needs less, but the key validation is still MS-AD. Now I'm taking a look at RHEV... and run into Oracle VM! Somebody had already take a look at Oracle VM? We need in primary a solid VM solution for an "enterprise

Hi, We had received a new EMC storage (Clariion CX4) and the EMC analist has told us that CentOS aren't on their support list, but RHEL are :) Well anybody on the list has a CentOS host talking (iSCSI) with an EMC storage, preferably using the EMC Powerpath software, and can talk about you experience? Or I will need to buy some REHL licenses ? I'll put my hands on it only next
