If I execute these via command line, will they persist after a reboot? Or, should I be putting these into a file like /etc/sysctl.conf? --------------snip-------------- /sbin/sysctl -w net.ipv4.tcp_max_syn_backlog=2048 /sbin/sysctl -w net.ipv4.tcp_fin_timeout=30 /sbin/sysctl -w net.ipv4.tcp_keepalive_intvl=10 /sbin/sysctl -w net.ipv4.tcp_keepalive_probes=7 /sbin/sysctl -w

Hey I need to run some pgp commands, -what's the name of the package supported by Centos that will allow me to work with pgp? I need to run pgp --fingerprint key.name or it's equivalent. Pro question. Google searches didn't show much, tried to search for pgp, gnupg, openpgp, pgp on centos, openpgp on centos, centos/pgp. No worthy results came back. Any advice? -karlski

I'm trying to install either 32-bit or 64 bit centos 4.3 and I keep getting an error: "No valid devices were found on which to install filesystems". In checking BIOS and RAID, everything seems fine, but I just found some research about I20. An alternative would be the i2o_blocks module. How can I install CentOS 4.3 x86_64 using i2o_blocks? How do I instruct the boot prompt to

Hi, Running a bunch of CentOS servers on 2U supermicro equipment, usually with 8 drives on Adaptec SmartRAID V or LSI Megaraid. In designing a rack in a data center, the question arises as to how to measure the amperage the server uses, prior to investing in power drops that actually do that for you, even remotely, for about $260.00-300USD per unit. This number is the important one these days

Hi, after reading the docs (no man page) and seeing a few example howtos, I see none for Centos specifically. I hereby offer to write this and even host it, and any other wiki-able howto you want, if you can school me on the first few steps relevant to how to link up the current rpmforge rpm for RHEL4-64. See, right now, the one for centos loads into the /usr/share/doc, which is an odd place

while i'm on a Centos5 kick, I was just curious if I simply needed to add a repo or if building these was a matter of waiting in terms of Centos5. Am trying hard to stay away from Fedora if possible... -krb

Hi, What's the best/safest way to "cat" the following job into crontab? */3 * * * * /usr/lib64/nagios/plugins/check_megaraid_passive.sh > /dev/null 2>&1 I am used to doing this manually via crontab -e, but now I simply have too many centos servers to build in a given week (get to toss another 120K at some more 2U chenbro/tyan/amd64's -w000ooo). -karlski

hey, any way I can install X onto the 'minimal build' via yum? I'd just reinstall, but am working with a 2TB system and it would take hours to re-do. Just curious... yum install __________________ I have rpmforge installed, so at least i'm pointed at the dag repos. -karl

Is it difficult to build cobbler on Centos or should I just go with Fedora on this one? Basically, if you have experience succeeeding at this, can you drop me a link to a Howto or describe the issues? I am only writing this because I tried, and ran into quite a few dependency issues with upstream/downstream packages, and would rather concentrate on just getting a nice working Cobbler (and

To extend space on our 64-bit centos FTP servers, we are considering setting them up to work with an existing PromiseRAID system via iscsi. -just curious if anyone here knows if iScsi is fast enough to serve up all the images? -might it be something where we get dedicated cards and put the iScsi traffic on its own Vlan? Just curious if this would hold up under alot of traffic, like weather

Hi, I'm just curious about setting up a new VPN here in the office part of our enterprise, as well as a second in our 75+ node data center co-location facility. Needing to stomp out the ****dows L2TP node here, just too many side-issues with config. I'd like it to run the same OS as all of our servers, e.g. Centos 4.3. Any recommedations on which software/server/client

Hi, I have alot of kickstart and scripting going on as I provision lots of machines, and every now and then I run into a pesky machine or three that's still got that Adeptec zero-channel RAID card sitting on the board. Normally I like to rip it our and throw something more robust in, but if it's a cache machine or whatever, I leave it in. It makes my kickstart file useless until I

Hi, Whats' the best motherboard you ever ran CentOS on? --------- Don't read this unless you have lots o' spare time, and please, no flamers or kook-jobs with wierd attitudes, this is just plain old hardware as it relates to centos talk -no politic or mean folks. Background (why I ask about centos-friendly hardware): As I order alot of servers, I have alot of vendors telling me

Hi, I am installing Centos ServerCD 4.4 64-bit on a new Supermicro board, the RAID BIOS looks fine, RAID 5, all 4 Seagate ES 250 GB drives show up as a single array in the RAID BIOS tool, and the OS install phase completes without a hitch. One thing I noticed was that the OS was loading the sata_nv driver and picking up the 4 Sata drives instead of the large RAID5 volume, it should just

Currently most machines I connect to use a display, but I want to run vncserver such that the display is always 0.

Hi, In populating our racks with several gigbit switches over the next few days, i'm wondering this: Is it over-engineering to seek out 550mhz rated cables over the typical Cat 6 250mhz rated cables? I've been advised (if you can a salesperson's words advice, heh.) that 250mhz is enough to handle traffic up to 10GB's. Should I just be happy with Cat6 for my GB switches or is

Hi, I'm running Centos 5 on an IBM x3550 series server with kernel version 2.6.18-8.el5 #1 SMP, dual xeon, 9GB ram system. When I run yum update, I get this error: --> Running transaction check --> Processing Dependency: libevent-1.1a.so.1()(64bit) for package: nfs-utils --> Finished Dependency Resolution Error: Missing Dependency: libevent-1.1a.so.1()(64bit) is needed by

How does one configure a fence device in the form of a NIC card in centos 5? Is the gnbd item relevant to this? I have posted the question to linux-cluster also, but they are much less active overall, -so if you have info, massively appreciated... -karl

Hi, Last time I was on Karanbir mentioned Puppet, -what do you all think of Cobbler? I plan to deploy one of the suggestions this week since it looks like i'll be dealing with 2000 centos systems instead of the few hundred I had predicted. -krb

am using cobbler to import via rsync -and having trouble munging paths properly to download the 64-bit dvd or others, -what's a known good rsync path to use, or a command line that would allow me to determine this myself? When I use the web browsers of course and go to centos.org, you'll get the usual "not a suppoorted protocol" when clicking around trying to isolate a good
