• How to accelerate and notice failure of potentially faulty disks

  - by rainier

  Hey, I got a bunch of 'used' servers, whose disks should have been checked, but they have been shipped around the county in crate which can't help. I just had one disk go bad (despite being mirrored, currently trying to get more details). The server was fine for about a week before everything ground to a halt this afternoon. Is there any way 'accelerate' the failure of faulty disks, with the goal of bringing the disk to failure before we launch production services? Would doing lots of I/O with 'dd' or 'iozone' be a good way to test these potentially faulty disks? Any other tests/tools that would help recognized failures before they happen?

• log execution of certain commands on linux

  - by jlsksr

  I have to maintain a system (debian) on which several users are allowed to install programs - so I would like to log, for example, if anyone executes "apt-get install" or "apt-get purge", so I can keep track of manually installed packages.. I'm looking for a general way to achieve this; it's not just APT, but several programs/scripts etc. Any ideas? /edit a google-search with few different keywords brought up this: http://serverfault.com/questions/201221/how-to-log-every-linux-command-to-a-logserver http://stackoverflow.com/questions/15698590/how-to-capture-all-the-commands-typed-in-unix-linux-by-any-user http://sourceforge.net/projects/rootsh/

• Automatically reboot Windows8 if no internet activity [migrated]

  - by Patrick

  I have a media server located in a very inconvenient part of my house. Occasionally I will have to reset my router or it will reset itself. The issue is the PC loses connectivity for some reason, and I am forced to walk outside, around the house, into the basement, over a bunch of toys and weights and boxes, to push a button to reboot it. I would love to have it check itself every 5-10 minutes and auto reboot if it is unable to ping a given address/IP. Any ideas how to accomplish this?

• slow disk writes between host and guest

  - by Jure1873

  I've got a ubuntu (server kernel) on a amd x4, 4gb ram, 2x seagate sata 1 tb disks for testing virtual machines and the write performance is very slow. The two disks are in a software raid1 array, one small boot ext3 partition, 10gb system partition and the rest is a xfs partition (about 980) gb for data (virtual machines). If I'm copying files from the virtual machine to the host with rsync or scp the copy frequently stalls or goes at about 1mb/s. What's wrong? I've tried disabling barriers on xfs, increased logbufs, allocsize, but it seems nothing helps. The strange thing is that await (for example during copying) for sda is usually under 100, while for sdb is around 400. Any ideas on what could be wrong / what could I do to improve this setup?

• Monitor status while using VNC

  - by kumar

  So after connecting to a vnc server via vnc viewer to my desktop (remotely), Is it possible to know whether the monitor connected to the CPU is switched ON or not. Simply put, from command prompt how do you know whether monitor is ON/OFF from command line. Here, Basically I am bit worried about privacy as my monitor can be viewed by anyone while accessed remotely. Any solution? Obviously there is a option to switch off the monitor while starting the vnc server at remote side but I am looking for a better solution to control monitor(possible??) remotely. Thanks!

• What kind of proxy acl rules should be applied?

  - by user42891

  I try to block sites in squid based on this article. Assuming you would want to block access to Yahoo (e.g http://www.yahoo.co.jp, http://www.yahoo.com, http://www.yahoo.co.in), you would ideally want to block all of the above URLs, if I use a regular expression and try to search something called yahoo it seems to get blocked. We are just interested in applying rules which would be most commonly used across all companies (e.g. social networking sites like facebook, orkut), porn sites (e.g. sex), gaming sites (games), movie & song download sites, and sites where they can upload data (e.g. rapidshare) What would be the common set of effective rules in achieving the above?

• Linux RAID0 - relocating member disk

  - by qdot

  I've got an issue I would rather handle with the array online - I am using RAID0 for temporary video storage - data that is low-cost to restore, but that is used frequently. The software array looks like this: md1 : active raid0 sdb1[2] sdc1[3] sdd1[0] sde1[1] 1953487616 blocks 64k chunks I have another partition (sda1) in this system, that I want to use to replace sdc1 (The drives are of varying age, and sdc1 is definitely the slowest one, limiting the entire array's sequential read performance to only 300MB/s). Is there a way to migrate the data from sdc1 to sda1 while the array is still online?

• How to monitor IO svctm with every 5 mins frequency using nagios?

  - by sabya

  I want to collect samples of iostat's svctm, await every 5 mins from all of my servers and store them in nagios. I want to get the values for what is happening in every 5 minutes (not since boot time, iostat's first output gives values since boot time). How can I do it in nagios? EDIT The tps should NOT be calculated #of transactions happened since reboot divided by uptime. What I want is # of transferred happened in last X mins divided X*60.

• default page in pnp4nagios

  - by bluszcz

  I am using pnp4nagios along with the nagios. Everything seems to be integrated properly - I have "extra action" icons close to every host and service which links to pnp4nagios graph. However, when I am going to the https://x.x.x.x/pnp4nagios/ it always change the url to the: https://x.x.x.x/pnp4nagios/graph?host=webhost01 How Can I turn off this behaviour? I would like to see on /pnp4nagios/ collected graphs from all servers.

• df says disk is full, but it is not

  - by Chris

  On a virtualized server running Ubuntu 10.04, df reports the following: # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.4G 7.0G 0 100% / none 498M 160K 498M 1% /dev none 500M 0 500M 0% /dev/shm none 500M 92K 500M 1% /var/run none 500M 0 500M 0% /var/lock none 500M 0 500M 0% /lib/init/rw /dev/sda3 917G 305G 566G 36% /home This is puzzling me for two reasons: 1.) df says that /dev/sda1, mounted at /, has a 7.4 gigabyte capacity, of which only 7.0 gigabytes are in use, yet it reports / being 100 percent full; and 2.) I can create files on / so it clearly does have space left. Possibly relevant is that the directory /www is a symbolic link to /home/www, which is on a different partition (/dev/sda3, mounted at /home). Can anyone offer suggestions on what might be going on here? The server appears to be working without issue, but I want to make sure there's not a problem with the partition table, file systems or something else which might result in implosion (or explosion) later.

• About Hard Disk Drive Docks

  - by Crossbrowser

  I'm thinking of buying a drive dock to put my unused large HDD to use. I will also probably use the dock to backup files and swap the drives regularly. I have a few questions though: Are they noisy? I plan to use them via USB (because I don't think I have eSata connectors), am I gonna want to kill myself every time I backup? (I know it's supposed to be 480 Mbps, but how realistic is this?) Do you recommend a particular model? (I was thinking about this Startech HDD dock) Thank you

• Creating rescue / install USB flash disk for CentOS

  - by wwwpanda

  For CentOS installation CDs, you can install OS, as well as booting into "rescue" mode so that you can do a chroot mount on the system partition for problem solving, even the system is installed in hardware RAID drives. How can we create a similar thing but on usb flash drive? I tried to do it with unetbootin, but when booting into the USB, eventually the CentOS setup still requires presence of CDs. Ultimately, I want to use this usb flash drive for remote disaster recovery through say HP iLo remote console / Dell iDrac etc.

• Program keeping encrypted files.

  - by Giorgi

  I am looking for a program which will encrypt files specified by me and allow me to view/edit/delete those files without creating a virtual disk. I do not want to have virtual disk as a domain administrator can access it so truecrypt is not the possibility. One possibility is to use winrar with password protected archive but winrar serves a different goal so it is not very user friendly for this purpose. If it's possible it would be nice if the program does not creates temp files while I open the files. Any suggestions?

• backing up ntfs disk using rsync on ubuntu

  - by user70366

  For a long time I was using windows. I have a separate drive I use to keep copies of my media files, photos etc. on, which I periodically backup to an external drive. In Windows I used SyncToy to do this. After my Windows stopped booting, I decided to switch to Linux (Ubuntu 10.10). That seems to be going fine, but now I want to backup my drive to the external drive like before. Mostly the two drives will be already the same with maybe about 10GB of extra files added. So I try to use rsync to synchronise the two drives like this: rsync --dry-run -rvlt --modify-window=1 /media/Antonio1TB/Backup /media/FREECOM\ HDD/Backup The problem is the dry run indicates that every file on the drive will be copied. Not just the files I have recently added. What is the correct command to synch two NTFS drives under Ubuntu so that files that already exist don't get copied again? Thanks.

• How to manage configuration software installations of non-domain Windows XP machines?

  - by Digi

  I have a large set of unattended Windows XP machines who are not connected to a domain or even to each other. I am struggling to find any tools out there that I can use to deal with them in one application. I am hoping to find software that I can perhaps install a client on each machine, then have it essentially proxy out configuration information and possibly commands (install, uninstall, stop service, etc) across the whole network. The closest I've come is Nagios and its client, but it cannot be used to push files through and run commands remotely. Any suggestions?

• Linux: Tool to monitor every process, execute-command, shortly, monitor what's happening at the moment

  - by Bevor

  Hello, due to a freeze problem of my Ubuntu 10.10 (it is not isolatable) I though about logging every executable of the kernel somehow in any file to see what happens last when a freeze occures the next time to not lose valuable information. I found acct but this is obviously not what I'm looking for. Actually it logs just user commands and those things. I need something which logs in a much "deeper" level. The best would be some kind of script which records every interrupt. Does anybody know some tool like that?

• Access a windows dynamic hard drive through a virtual machine on ubuntu?

  - by Enigma

  I have a Windows 7 OS and am thinking about transitioning to a dual boot set up with Ubuntu 12.04. From what I recall, it is not possible to natively access Dynamic Windows Partitions in a Linux OS. My thought is that it might be possible to have a virtual machine (running windows) installed within Ubuntu access the physical dynamic drive. The problem comes to whether VMWare can access the physical disk "high enough" to be able to mount it within the windows virtual machine as a native device or if it gets passed through from the native Linux OS. This is really the only thing holding me back from switching to a dual-boot set up as the dynamic disk is made up of 4 or 5 hard drives and I would very much like access to the data on both OS's. Alternatively, is there another solution for combining multiple physical hard drives into one virtual hard drive that would be readable on both OS's?

• How to mount encrypted volume at login (Ubuntu 12.04, pam_mount)

  - by Nick Lothian

  I'm trying to get pam_mount working on Ubuntu 12.04. I have /dev/sda1 (encrypted partition) with /dev/dm-1 (ext4 formatted) inside it. Should ~/.pam_mount.conf.xml be trying to mount /dev/sda1 or /dev/dm-1? If I use the line: <volume fstype="ext4" path="/dev/dm-1" mountpoint="~/slowstore" options="rw" /> then it nearly works. It prompts for the password (ok, I'd like pam_mount to do that for me, but still..) then I get: pam_mount(rdconf2.c:126): checking sanity of luserconf volume record (/dev/dm-1) pam_mount(rdconf2.c:132): user-defined volume (/dev/dm-1), volume not owned by user If I do: sudo chown nick:disk /dev/dm-1 Then re-login the encrypted partition mounts correctly (ignoring th fact I have to reneter the password). However, if I log out completely the ownership on /dev/dm-1 gets reset to root:disk. What am I doing wrong?

• spontaneous hard disk password

  - by sc

  I had an HP proliant server go down recently. All of the sudden the sas controller (e200i) would not see any of the physical disks. New disks were detected just fine. I thought it was odd that all 6 disks would go down at one time so sent them to a data recovery firm to find out what happened. I'm being told that, somehow, all of the disks were spontaneously password protected. These are Hitachi 2.5" drives and I guess this is something of a known issue. The company has worked for a while to try and recover them, with no luck. Has anyone had experience with this? Any recommendations for how to recover the drives or a company that might have the expertise to do so?

• How to find malicious IPs?

  - by alfish

  Cacti shows irregular and pretty steady high bandwidth to my server (40x the normal) so I guess the server is udnder some sort of DDoS attack. The incoming bandwidth has not paralyzed my server, but of course consuming the bandwidth and affects performance so I am keen to figure out the possible culprits IPs add them to my deny list or otherwise counter them. When I run: netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n I get a long list of IPs with up to 400 connections each. I checked the most numerous occurring IPs but they come from my CDN. So I am wondering what is the best way to help monitor the requests that each IP make in order to pinpoint the malicious ones. I am using Ubuntu server. Thanks

• gmetric data submitted doesn't follow dmax value

  - by 580farm

  I have a custom script that is querying a metric port for an application that I'm running and submitting parsed values to ganglia via gmetric. The script runs every minute, so I submit the data to ganglia using the following gmetric options: /usr/sbin/gmetric -g ec2 -s positive -t uint32 -d 600 -n "$NAME" -v $VALUE -x 60 But for some reason there are still gaps in the graphing data: Is there something in my formatting that is preventing the dmax/ttl of the last metric received from being honored? Is there anyone who does custom metric collection that has run into this problem before that can shed some insight or provide some tips as to how to best correct this?

• How to log Windows server share connections?

  - by sbussinger

  Can anyone make a suggestion for the best way to log connections and disconnections from Windows workstations to a Windows Server 2003 file share? We're having some issues with workstations that have a drive mapped to a server that seem to work fine for awhile and then suddenly appear to get disconnected from the server (with files open). Needless to say this causes some data corruption and error messages. It would help me to troubleshoot the problem if we could somehow monitor and log the session connections and disconnections, to attempt to correlate the connectivity issues with what actions the user is taking at the time and what the server is doing. I just haven't been able to find a way to do this. Specifically I'm talking about the same information that is displayed in the Computer Management control panel applet in the "System Tools|Shared Folders|Sessions" page. Thanks!

• Linux foxboard network monitor

  - by het.oosten

  I want to use a Foxboard a simple network monitor for multiple routers (all routers are connected to the internet). Foxboard is a mini pc with an embedded version of Debian. My idea is to use multiple virtual network devices like this: eth0 192.168.2.10 eth0:1 192.168.3.10 eth0:2 192.168.4.10 I found a nice Python script to ping an external host here (the solution from Ryan Cox): http://stackoverflow.com/questions/316866/ping-a-site-in-python Is it possible to configure Debian to use eth0 when I ping www.site-a.com and eth0:1 when I ping www.site-b.com?

• How can I see how much bandwidth each Apache Virtual Host is using?

  - by pkaeding

  I have Apache set up to serve several Virtual Hosts, and I would like to see how much bandwidth each site uses. I can see how much the entire server uses, but I would like more detailed reports. Most of the things I have found out there are for limiting bandwidth to virtual hosts, but I don't want to do that; I just want to see which sites are using how much bandwidth. This isn't for billing purposes, just for information. Is there an apache module I should use? Or is there some other way to do this?
