We're looking for tools to be used in monitoring the PERC H800 arrays on a set of database servers running CentOS 5.5. We've installed most of the OMSA (Dell monitoring) suite. Our current alerting is happening through SNMP, though it's a bit hit or miss (we apparently missed a couple of earlier predictive failure alerts on one drive). OMSA conflicts with mega-cli, though we may

I'm used to Debian-based distros which have a tempfile(1) utility for safely and sanely creating temporary files. There isn't a comperable utility for RHEL/CentOS systems. I've been exercising Google-fu looking for a good robust tempfile generation idiom, but haven't turned one up yet. Hence this appeal to the lazyweb. -- Dr. Ed Morbius, Chief Scientist / | Robot

I'm looking for suggestions as to a good general method of remote-logging services such as nginx or anything else which doesn't support syslog natively. I'm aware that there's an nginx patch, and we're evaluating this. It may be the way we fly. However there are other tools which may not have a patch for which remote logging would be useful. If there's a general soution

I'm looking for a capability similar to Debian/Ubuntu's pre/post up/down network commands capability. The problem: we've got a colo in which hosts talk directly to the hosting provider's router (through a bridging firewall) and hence our hosts MAC addresses are cached by the router. We should be able to solve this by pinging the router directly when bringing up the interface,

We've been wrestling with this for ... rather longer than I'd care to admit. Host / initiator systems are a number of real and virtualized CentOS 5.5 boxes. Storage arrays / targets are Dell MD3220i storage arrays. CentOS is not a Dell-supported configuration, and we've had little helpful advice from Dell. There's been some amount of FUD in that Dell don't seem to know what

Hi All, I am thinking about an idea, but it requires that I be able to watch several directories for files that are added, deleted or maybe changed. Let start with adding files. What tools are available for me to watch a directory. In an example, if a file is added to a directory I want to run a shell script that will do some conversation on the file to produce a second copy. I have the shell

Hi, this is the first time I install linux on a dell server. Simply I booted from a centos 5.5 x64 dvd but I cant see the disks.. is there something I miss ? thanks very much for any help luigi

I know this is a Linux 101 question, however I am unable to locate the answer in my O'Reilly Linux book: how to set the default for permissions when creating a new user. The default for the GUI in my newly installed Centos 5.5 is 700. I usually use 774. And when root creates a new directory, is there a way to have a default there too? Lastly, if root or someone with root privileges

I really like gnu screen and use it everyday but there's one thing that is a bit inconvenient, and that's the odd line wrapping and terminal size issues that seem to pop up. The problem crops up when I type or paste a really long command, and then go back and try to edit it; the text starts to wrap over itself and you have no idea what you are editing. Any fixes for this?

Dear CentOS, I have a user group that would like to be able to routinely post (easily) emails to a web site. Must be usable without special training. I have no experience with this. Anyone have a suggestion? LAMP stack installed.

Well, today, I feel like a real, old time sysadmin. Now, I didn't have to write a driver in assembly for the printer, but.... We got this huge, 44" HP Designjet z3200ps printer. Only supports Win and Mac. Fine, I hang it off of one of our servers on a subnet (at $0.96/foot paper, we're the only ones who print on it....). Then I'm thinking that all I really need is a .ppd.

Hi, Can someone recommend a good vulnerability scanning service? I just need the minimum for PCI compliance (it's a sort of credit card processing certification). I got a free scan from https://www.hackerguardian.com/ and their scan reported a number of "Fail" results. I haven't checked them all yet but most seem to be things for which fixes were backported looong ago by The

Hi I need to store about 250.000.000 files. Files are less than 4k. On a ext4 (fedora 14) the system crawl at 10.000.000 in the same directory. I tried to create hash directories, two level of 4096 dir = 16.000.000 but I had to stop the script to create these dir after hours and "rm -rf" would have taken days ! mkfs was my friend I tried two levels, first of 4096 dir, second of 64

I have a kvm virtual host running on what will become CentOS 6 with 12GB of memory and a Quad Xeon X5560 2.8Ghz . The store for virtual machines will be a software raid 6 array of 6 disks with an LVM layered on top. I'm not initially planning any major overcommitment of resources, though there could be a need for some overcommitment with a light workload on the guests. In recent years

Hi -- I'm running a server which is usually stable, but every once in a while it hangs. The server is used as a file store using NFS and to run VMware machines. I don't see anything in /var/log/messages or elsewhere to indicate any problem or offer any clue why the system was hung. Any suggestions where I might look for a clue? -- Michael Eager eager at eagercon.com 1960 Park Blvd.,

I have been trying to get the Personal Information Manager Sidekick to run on Wine and Crossover. Our company is trying to move over to ubuntu(still fairly new) and after two weeks of searching i have yet to find a contact manager with the functionality and flexibility of sidekick so we are trying to get it working in Ubuntu. The program runs fine but then instantly crashes when i attempt to

Hi folks, currently I'm running Dovecot 1.2.1. Compiled from source on Fedora 10 Linux 32 Bit (all patches). Clients are Pine 4.64, Thunderbird 2.0.0.22 and Mutt 1.5.20 (using "=b" for server-side searching). When a message contains the text "under_score" and I let the server search for it, Dovecot does not find it in messages with a Content-Transfer-Encoding of
