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

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

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

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, 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, We have patched Centos 4.4 to work properly with the recent DST changes, but our customers are reporting wrong FTP client timestamps based on which areas they live in. What are the two main mechanisms in Centos that control time? I know about /etc/localtime and TZDATA, is there something we may have missed? Or is this perhaps a VSFTPd thing and I could go bug that list? To be clear,

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

hey all, I perused my inbox looking for this subject, but not finding it, -anything I need to keep my server farm of 60 centos servers (that all run ntp) going smoothly during this next time change on March 11? I noticed on the w2k side my IT staff have to do some scrambling, heh, but that's expected. Any action required? -karlski

hey I already compiled apache 2.0.58 from source onto my centos server and noticed I needed to get SSL module added "after the fact" -what are the commands I would run to get this working without wiping everything out and starting over? -karlski

Is there a specific way to set a name server so that clients are always *forced* to use an autoritative name server? UltraDNS and some others have mentioned little features they have, but it only hints at the possibility that somewhere in the DNS spec. -karlski

Howdy all, Any recommendation as to the right way to config X. Last time I did was using X86Setup back in OpenBSD 2.7 days. What's the Xorg tool? How do I invoke it? Looks like I just need to fix the ranges, maybe they mean sync vert & horiz or something. Or should I be typing gdm instead of startx? Any advice? -below are some errors, infos, although the dmesg didn't pipe out

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

Is there anyone who has successfully put together a "high-powered" mini-itx ZFS box that would be willing to post their system specs? I''m eyeballing the KI690-AM2... http://www.albatron.com.tw/english/product/mb/pro_detail.asp?rlink=Overview&no=239 ...but am having a difficult time locating it and a suitable case currently. I was in negotiations with a hardware source,

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

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, 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

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
