hi! does anyone has a good howto, docs how to set up an smtp, pop3, imap server, with webmail, and has anti virus solution, and even spam filtering? :D [plus secure connection for the clients :D ] wich softwares are the best for this? [e.g.: "vsftpd is the most secure ftp server"..] users would be from /etc/passwd [so not virtual users] thank you! p.s.: I've already googled :(

I am running software RAID1 on a somewhat critical server. Today I noticed one drive is giving errors. Good thing I had RAID. I planned on upgrading this server in next month or so. Just wandering if there was an easy way to fix this to avoid rushing the upgrade? Having a single drive is slowing down reads as well, I think. Thanks.

hi, I am planning to replace my old CentOS 6 mail server soon. Most details are quite obvious and do not need to be changed, but the old system was running on spinning discs and this is certainly not the best option for todays mail servers. With spinning discs, HW-RAID6 was the way to go to increase reliability and speed. Today, I get the feeling, that traditional RAID is not the best option for

I just wrote a little script, that will echo a message to the user, if it doesn't have enough permission: $ if ! [ "$(env LC_MESSAGES=C ifconfig wlan0 down | grep -i denied)" == "" ]; then echo "no permission"; fi SIOCSIFFLAGS: Permission denied $ sudo su [sudo] password for USER: # if !

ust can't find a script that generates a valid MAC address :S Has anyone has one? thank you -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20091023/ca91ea82/attachment-0002.html>

hi I know that I could use ssh tunneling: ssh -fND localhost:6000 SOMEBODY at 192.168.56.5 -p PORTNUMBER to surf the web through another machines internet connection -> I just need to set Firefox to use proxy 6000. But: How can I set that on the client side, to e.g.: ping through the machine with openssh-server? Not just setting Firefox to use port 6000. Is there any method for

I have configured 2x 500G sata HDD as Software RAID1 with three partitions md0,md1 and md2 with md2 as 400+ gigs Now it is almost 36 hours the status is cat /proc/mdstat Personalities : [raid1] md0 : active raid1 hdb1[1] hda1[0] 104320 blocks [2/2] [UU] resync=DELAYED md1 : active raid1 hdb2[1] hda2[0] 4096448 blocks [2/2] [UU] resync=DELAYED md2 : active raid1

Hi Everyone, I am stack between two identical systems (2U Twin2, 4 nodes, SuperMicro) servers that have the same exact specs except for HDDs. These nodes will all either have Asterisk installed with CentOS or will have Asterisk install in virtual environment. Option 1: *12* x 3.5" HDD (3 HDDs per node) Option 2: *24* x 2.5" HDD (6 HDDs per node) **both options come to the same price.

Hello again. Do any of you have one of the 'new' HDDs with 4kB Sectors currently in use? I would upgrade to the 4kB disks but I don't know if this might be problematic as I intend to use ZFS w/ RAIDz or at least a classic RAID6. How might this affect performance under 5.5 and how do I go about setting up the alignment of the partitions I use? Kind regards Dawid Horace

I got the email that a drive in my 4-drive RAID10 setup failed. What are my options?

Something seems to be wrong with my file systems, and I want to fsck everything. But I cannot. The setup consists of 2 hds, carrying 3 raid1 (ext3) file systems (boot, /, swap). OS is up-to-date CentOS 5. So I boot from CentOS 5.3 dvd in rescue mode, do not mount the file systems, and try to run fsck -y /dev/md0 fsck -y /dev/md1 fsck -y /dev/md2 For each try I get an error message:

(Resend: message didn't show, was my original message too big? Posted one of the output files to a website to see) The point of RAID1 is to allow for continued uptime in a failure scenario. When I assemble servers with RAID1, I set up two HDDs to mirror each other, and test by booting from each drive individually to verify that it works. For the OS partitions, I use simple partitions and

I'm running CentOS 5.9 x86_64 on a machine I built myself that has 6 SATA II hard drives (4 - 1 TB drives; 2 - 1.5 TB drives) all in several RAID-1 arrays. These arrays were created when I did the original installation with CentOS 5.1 and each created partition (both standard and LVM) were built raid 1. Due to some things happening around the house that required most of my attention, I

So I'm in the process of building and testing a raid setup and it appeared to take along time to build I came across some settings for setting the min amount of time and that helped but it appears that one of the disks is struggling (100 utilization) vs the other one...I was wondering if anyone else has seen this and if so, is their a solution for it...my 2 disks are 1 Samsung F3 1tb /dev/sdb

Hi list, I've a notebook with C7 (1511). This notebook has 2 disk (640 GB) and I've configured them with MD at level 1. Some days ago I've noticed some critical slowdown while opening applications. First of all I've disabled acpi on disks. I've checked disk for badblocks 4 consecutive times for disk sda and sdb and I've noticed a strange behaviour. On sdb there are
