  • I lost /dev/md2 on my server

    - by sten
    Hi, My 2 hard drives fried at the same moment apparently. My host company rebooted my server in rescue mode and I am trying to recover my data. They told me to mount /dev/sda2 to recover the data I need but, looking at a similar server that I have in pool, the data I'm looking for should be instead in /dev/md2. I can find /dev/md0 but not /dev/md2 (nor /dev/md1). I've looked on several places on the web and I could only find messages explaining how to create new partition. I just need to recover some data, not all of it and I'll be glad if anyone could help me to mount the /dev/md2 folder (or any other trick that would allow me to recover the data that was stored there). Thanks in advance, Sten

  • 2.6.9 Kernel on virtual server (non upgradable) - any expected problems?

    - by chris_l
    Hi, I'm considering to rent a virtual server (for me personally). The product I'm currently looking at offers IMO fair pricing, very good hardware etc. The only problem is, that I won't be able to do an upgrade to a newer kernel than 2.6.9 (running Debian Etch). Also, I can't install my own kernel modules. (The server runs with Virtuozzo, so as far as I understand it, it just does some chroot instead of a real virtualization (?)) I want to run GlassFish, Postgres, Subversion, Trac and maybe some other things on it. It will also have to employ a firewall, and provide OpenSSL for https. Ideally, it would also be able to do AIO (asynchronous IO), which could speed up some server I/O. Should I expect problems with that old kernel version, in conjunction with the software I want to install (I'd like to use current versions of the software)? One thing I already found out, is that you can't do everything with iptables, since some kernel modules are missing/things are not build into the kernel. GlassFish v3 appears to run fine at first glance. I was able to test the server for a few hours. Installing my whole setup wasn't feasible in that time, but what I can say is, that it's amazingly fast for an entry-level vserver, especially hard disk and network performance (averaging at ca. 400MBit/s). So if the kernel won't be a problem, I'd really like to take it. Thanks, Chris PS Exact kernel version: 2.6.9-023stab051.3-smp

  • Kernel compiling with -j2+ parameter ends prematurely with no error message or output bzImage

    - by Minix
    I've noticed quite a while ago that compiling a kernel with the parameter -j set to 1 or more doesn't produce a bzImage. Instead, it ends prematurely without any advice. I have reproduced the same behavior in both my netbook and home server. As far as I'm aware, the point where the compilation stops is random - Compiling twice with the same parameters will probably stop at different files. However, when I run make with no -j* parameter the compilation ends just fine and outputs a working bzImage. Both machines run Intel Atom (N270 on the netbook and 330 on the server) and I've compiled for these processors. If I recall correctly, I've tried compiling both with Atom and with generic x86_64 options. The kernel version I'm building is 2.6.34.1 I've always compiled normally with those options in my Core2Duo and Pentium Dual Core machines. Has anyone experienced this issue? Any ideas why does this happens? Is there a fix or workaround?

  • How to securely control access to a backend key server?

    - by andy
    I need to securely encrypt data in my database so that if the database is dumped, hackers are unable to decrypt the data. I'm planning on creating a simple key server on a different machine, and allowing the DB server access to it (restricted by IP address on the key server to permit the DB server). The key server would contain the key required to encrypt/decrypt data. However, if a hacker were able to get a shell on the DB server, they could request the key from the key server and therefore decrypt the data in the database. How could I prevent this (assuming all firewalls are in place, DB is not connected directly to the internet, etc)? i.e. is there some method I could use that could secure a request from the DB server to the key server so that even if a hacker had a shell on the DB server they'd be unable to make those same requests? Signed requests from the DB server could make issuing these requests less trivial - I suppose that'd help increase the amount of time it'd take to compromise the key server, something a hacker probably wouldn't have much of. As far as I can see, if someone can get a shell on the DB server everything's lost anyway. This could be mitigated by using one key per data item in the DB so at least there's not a single "master" key, but multiple keys that the hacker would need to access. What would be a secure method of ensuring requests from the DB server to the key server were authentic and could be trusted?

  • Does urandom share the same entropy of random?

    - by ???
    Does the entropy pool /dev/random used the same to /dev/urandom? I want to mknod /dev/random 1 9 to replace the slow random, I think the current entropy is randomly enough, if urandom is based on the same entropy, and all succeed random numbers are generated based on that entropy, I don't think there'll be any vulnerable.

  • Which rdisk value in boot.ini maps to which disk?

    - by MA1
    Following are the contents of a sample boot.ini: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /NOEXECUTE=OPTIN /FASTDETECT multi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows 2000 Professional" /fastdetect multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /NOEXECUTE=OPTIN /FASTDETECT The rdisk value tells the physical disk number. So, if I have three hard disks say: /dev/sda /dev/sdb /dev/sdc Then how to know which disk (/dev/sda or /dev/sdb or /dev/sdc) is rdisk(0) and which disk is rdisk(1), etc.?

  • Debian - Problems Unmounting External Hard Drives

    - by user331981
    I recently installed Debian Testing on a new laptop and I just noticed that I am having some issues with unmounting external hard drives. I am using Mate Desktop 1.8.1. With the 1st drive, if I right click on the drive and select “safely remove”: The drive unmounts, spins down, immediately spins back up an remounts. Unable to unmount. With the 2nd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down. With the 3rd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down, immediately spins back up but does not remount, and after 20 seconds, it spins down and stays that way. Behavior is the same on both USB 2.0 and USB 3.0 ports. On my last laptop, on which I also used Debian Testing + Mate desktop, the safe removal of drives worked out of the box and I never had an issue with it. The drives would unmount, spin down and stay that way. To remount the drive, one needed to unplug the device and plug it back in. I am unsure how to troubleshoot this issue and I am not sure if it is merely a matter of installing a “missing” package of editing a config file. Thank you in advance.

  • How can I get the comment of the current authorized_keys ssh key ?

    - by krosenvold
    Edit: What I really need to know WHICH ssh key from authorized_keys has been used to identify the currently logged on user. According to "man sshd": Protocol 2 public key consist of options, keytype, base64-encoded key, comment. I see that when I use ssh-keygen, the comment is usually the local identity of the user. Is there any way to access this value when I'm on the remote computer ? (Kind of like the SSH_CLIENT shell variable) (Assuming I enforce the comment to be a remote identity of some sort, I would like to log this from a shell-script! This is on ubuntu)

  • How can I redirect HTTPS(S) traffic to anothr gateway?

    - by PsyStyle
    I have a network like 192.168.0.0/15 with the default gateway set to 192.168.0.1. Al the workstations of the network use this gateway for all kind of accesses to the Internet. Now I am testing a new Internet connection with another provider and for this I am using a second gateway on the same subnet with 192.168.0.2 as IP address. I want to redirect only HTTP and HTTPS traffic to this second gateway without touching the address of the default gateway set inside every workstation. How can I accomplish this task? What I have to change inside the first's gateway firewall configuration or routes? I tried with a dnat like DNAT loc:192.168.0.1 loc:192.168.0.2 tcp 80 but nothing worked. I use Shorewall for simplicity in configuration but I can understand even theorical answers which I will try to adapt to my case

  • apache: lists of all directives for a context?

    - by ajsie
    in the apache online documentation each directive could belong to a context eg: server-config, virtualhost, directory, .htaccess and so on. i wonder if there is a list of all directives belonging to each context? eg. a list with all directives for virtualhost so i know exactly which one i can use? and also, where can i find directives for apache modules? on their page or does each module has its own page with documentation (eg. mod_rewrite)?

  • how to know which display number for the variable DISPLAY to be exported when ssh to server

    - by insidepower
    When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only export DISPLAY=localhost:0 && xclock export DISPLAY=localhost:1 && xclock export DISPLAY=localhost:2 && xclock export DISPLAY=localhost:... until the clock appear. Then i will use that display number. Each time log in to the server, the display number which is able to tunnel the gui data correct would be different. I know many of such similar questions has been asked and answer. However I couldn't find answer to my question, anyone know about it? Thanks!

  • What is the best time to set the IP address for a server headed to a server colocation facility?

    - by jim_m_somewhere
    What is the best time to set the IP address for a server? I have a server that I am going to install the OS on and then I am going to send it to a server colocation facility. The server is going to have Internet facing services (www, email, etc.) I can set up a "fake" IP address during install (by fake I mean private as in RFC 1918) and change the "fake" IPs to the real IPs once I set up the colocation service. The other option is to set up the colocation service...wait for them to give me the "real" IPs and use them during the OS install. The ramification are that...if I use "fake" IPs during install...I will have to wait before I set up things like SSL certs. If I wait for IPs from the colocation provider...then I can set up SSL certs that use the "correct" (as in "real") IP addresses...no changes to the certs until they expire. Do the "gotchas" of changing an IP address on a server outweigh the benefits of a quick install? The other danger with using "fake" IPs is that I could make a mistake when I go through the various files to change the IP address to the "live" IP address. Server OS: CentOS 6.2 or CentOS 6.3, 64 bit. Apps: Apache 2.4.X httpd, MySQL 5.X (will eventually use replication)

  • Continue process after closing terminal?

    - by Jakobud
    Recently, I tried to unzip a 30 gig zip file on a remote system using Putty. As the long unzipping process continued, I closed Putty, assuming that the process would just continue to run on the remote machine. When I came back later and logged back into the machine again, I realized that the process must have stopped only part way through when I closed Putty. I wasn't expecting that to happen. My question is, how do I prevent this problem? Can I somehow fire off a process in the background? Or should just setup a one time cronjob that will run the process for me?

  • Availability of big files on multiple servers

    - by Imises
    I have to handle many (1'000 - 30'000) big files ranging from 200MB up to 2GB. The demand for these files is variable (0 - 300 downloads / file). This is why a single file must saved on 2 or more servers. My servers are placed in different datacenters (France), with different size HDDs (750GB to 4TB). Currently I share the files using PHP and ncftpget / ncftpput, but it's very slow. I need a solution to handle balancing these files across 7+ servers.

  • Run script on login with ssh

    - by user912447
    I have a feeling this is quite easy to do but every solution found on google has to do with adding a script to be run whenever someone logs into the machine. What I am looking for is a way to run a script when only I log into the machine. I ssh into a shared computer and need to have it load a couple modules for me and I imagined the easiest way to do this would to just run a script on login. Is there a simple way?

  • Do control groups improve system performances?

    - by qdii
    According to this website, enabling cgroups in the kernel can boost performances by sharing resources in a better way. In particular, the conclusion states that:  Nevertheless, with a little trial and error, cgroups can help you improve the efficiency of your systems’ resource usage and avoid downtime due to overusage of a single service. Kernel seeds, however, recommend to deactivate them altogether. They say: Consider these [kernel] settings poison. They remain nothing but system slow-downs. They are all off by default [in the proposed kernel config file]. Who should I trust?

  • Access denied for user 'root@localhost' (using password:NO)

    I am attempting to install a network management package called cacti onto Ubuntu running under Windows Virtual PC. I attempted to install MySQL as it is one of cacti's dependencies. I can install and start the MySQL server, but whenever I try to access it in any other way, such as to change the password, I get the error message Access denied for user 'root@localhost' (using password:NO). I would like to know what is causing this and how to fix it. Edit: (just in case my comments are not visible) The answers from HD and Devin Ceartas did not work for me.

  • Redirect non-www ssl traffic to www ssl (apache)

    - by The NinjaSysadmin
    Hello, I'm attempting to get a redirect which is failing, and for some reason I can't think today. I have a vHost file within HTTPD that listens on standard port 80 and port 443. I'm attempting to redirect https://domain.com/(.*) to https://www.domain.com/$1 so that the URL remains intact. My config is as follows: ServerName www.domain.com ServerAlias tempdomain.testdomain.co.uk ServerAlias domain.com My rerwrite rule I'm using is. RewriteCond %{HTTP_HOST} ^domain.com$ RewriteRule ^(.*)$ https://www.domain.com$1 [R=301,L] I've also tried removing the . and $ but nothing.. When I visit the url https://domain.com/secure.page?action=comp it doesn't redirect to https://www.domain.com/secure.page?action=comp I do also have other SSL pages, the above was just an example.. Can anyone point out my stupidity.
