• Could it be that "chkrootkit" just doesn't like .hmac, .packlist, and .relocation-tag files?

  - by Danijel

  I just cleaned up my hacked CentOS server (due to not updating since versino 5.3). But still, "chkrootkit" says this: Possible t0rn v8 \(or variation\) rootkit installed /usr/lib/.libfipscheck.so.1.1.0.hmac /usr/lib/.libgcrypt.so.11.hmac /usr/lib/.libfipscheck.so.1.hmac /lib/.libcrypto.so.0.9.8e.hmac /lib/.libssl.so.0.9.8e.hmac /lib/.libssl.so.6.hmac /lib/.libcrypto.so.6.hmac /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/Text/Iconv/.packlist /usr/lib/perl5/5.8.8/i386-linux-thread-multi/.packlist /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/HTML-Tree/.packlist /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/Font/AFM/.packlist /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/MLDBM/Sync/.packlist /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/MLDBM/.packlist /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/FreezeThaw/.packlist /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/Apache/ASP/.packlist /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/HTML-Format/.packlist /usr/lib/gtk-2.0/immodules/.relocation-tag /usr/lib/python2.4/plat-linux2/.relocation-tag /usr/lib/python2.4/distutils/.relocation-tag /usr/lib/python2.4/config/.relocation-tag Could it be that "chkrootkit" just doesn't like .hmac, .packlist, and .relocation-tag files? Are these realy still infected?

• How to disable monitor "sleep" on Ubuntu without access to X?

  - by exhuma

  I just received a CuBox (basically a tiny ARM based PC). It comes pre-installed with Ubuntu, and I did not (yet) want to fiddle with the OS itself. My aim is to have it automaticall start a browser in fullscrren upon boot. Using chromium with the "--kiosk" flag works perfectly in that regard. But now I have the problem that the screen turns off after a certain time. I managed to turn off the screen saver using: gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false And tried to turn off the power management using: gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0 and gconftool-2 -s /apps/gnome-power-manager/timeout/sleep_display_ac --type=int 0 Neither of the power-management commands worked. Theoretically I could hook up a mouse and keyboard and configure it manually. But I want to learn how to do it over the console. The box will eventually be only reachable via SSH. So I'd like to be able to trouble-shoot it later. I don't quite know where to look for. I searched the gconf tree using gconftool-2 -S for anything related to the terms power, idle and sleep but did not find anything promising. Maybe it's not even gconf related... Any ideas what else I could look for?

• ldap-authentication without sambaSamAccount on linux smb/cifs server (e.g. samba)

  - by umlaeute

  i'm currently running samba-3.5.6 on a debian/wheezy host to act as the fileserver for our department's w32-clients. authentication is done via OpenLDAP, where each user-dn has an objectclass:sambaSamAccount that holds the smb-credentials and an objectclass:shadowAccount/posixAccount for "ordinary" authentication (e.g. pam, apache,...) now we would like to dump our department's user-db, and instead use authenticate against the user-db of our upstream-organisation. these user-accounts are managed in a novell-edirectory, which i can already use to authenticate using pam (e.g. for ssh-logins; on another host). our upstream organisation provides smb/cifs based access (via some novell service) to some directories, which i can access from my linux client via smbclient. what i currently don't manage to do is to use the upstream-ldap (the eDirectory) to authenticate our institution's samba: i configured my samba-server to auth against the upstream ldap server: passdb backend = ldapsam:ldaps://ldap.example.com but when i try to authenticate a user, i get: $ smbclient -U USER \\\\SMBSERVER\\test Enter USER's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.6] tree connect failed: NT_STATUS_ACCESS_DENIED the logfiles show: [2012/10/02 09:53:47.692987, 0] passdb/secrets.c:350(fetch_ldap_pw) fetch_ldap_pw: neither ldap secret retrieved! [2012/10/02 09:53:47.693131, 0] lib/smbldap.c:1180(smbldap_connect_system) ldap_connect_system: Failed to retrieve password from secrets.tdb i see two problems i'm having: i don't have any administrator password for the upstream ldap (and most likely, they won't give me one). i only want to authenticate my users, write-access is not needed at all. can i go away with that? the upstream ldap does not have any samba-related attributes in the db. i was under the impression, that for samba to authenticate, those attributes are required, as smb/cifs uses some trivial hashing which is not compatible with the usual posixAccount hashes. is there a way for my department's samba server to authenticate against such an ldap server?

• I can't get my PC to start up by a normal way.

  - by ssice

  I couldn't write a more accurate title. I am just unable to start the computer by pressing the Power On button. I checked the Power Supply and it seems to give good voltage values in every pin. And this is not a BIOS malfunction because of bad overclocking or anything that may come to your mind. And I will tell you why. It happens that EPS (or any ATX-based) power supply has the ability to be powered-on by the Motherboard by jumping the 13th pin of the 24-pin-ATX-connector to COM/GND. I did it, after pushing the power on button (without any visual response) and, pwhaa! The machine turned on. I was able to read (and even write, if I wanted) BIOS values and then start any OS installed. Machine starts, so it's not any kind of misconfiguration. It seems some hardware related. I am able to power the machine on only if I already pushed the power on button. Though pushing it without jumping the 13th pin to ground for a second does not power the machine. Of course, jumping the pin without pushing the power on button does not tell the motherboard anything, so the computer would not start up either. It's as if the logic that connects the power button with the 13th pin derivation to GND was unable to be activated. What can be the issue? How can I solve it? My configuration is as follows: CPU: AMD Phenom 9850 X4 Black Edition MB: ASUS Formula II AM2 RAM: 2x2GB Corsair Dominator 5-5-5-15 2T @ 1066MHz DDR2 Tested also with only 1 module GPU: 2x XFX nVIDIA GeForce 9600 GT XxX Alpha Dog Edition @ Core: 540Mhz [SLi] Power Supply: Xilence 700W (ATX 12V 2.3 / EPS 12V 2.92 compatible) PS: I know the machine is like 2 years old. I hardly use it now, but my parents do.

• How to determine if my AWS/EC2 server has been compromised / resolution?

  - by ElHaix

  I have recently seen an increase in network in/out activity on my server and am trying to determine if my AWS/EC2 instance has been compromised, and if so, how to resolve? In my security group I have: Inbound: 80 (HTTP) 0.0.0.0/0 Outbound: 80 (HTTP) 0.0.0.0/0 443 (HTTPS) 0.0.0.0/0 Using TCP-UDP Endpoint Viewer: I see a lot of w3wp.exe TCP processes with varying local ports http and numbered, as well as varying remote ports. Some processes go red/yellow/green on updates . I see Remote address for most w3wp processes are my ec2 instance, however I am seeing several to *.deploy.akamaitechnologies.com and *.deploy.static.akamaitechnologies.com with received bytes varying between 4-11 megs. I also see Ec2Config.exe, remote address: 169.254.169.254 System Process Remote Address: fetcher4-4.p.mail.ru (how can I get rid of this one?!) local port: http remote port: 33432 I am also seeing some system processes from 114.216-244-93-rdns.wowrack.com: Protocol: TCP local port: http remote port: varying As well as some baiduspider "System Process"'s. I'm afraid that my system may have been compromised, and wondering if these results are any indication of that. If so, how can I get eliminate these possible threats? I have MS Security Essentials installed.

• Building vs buying a server for an academic lab [closed]

  - by Roy

  I'm looking for advice on the classic build vs buy question. We need a new linux server to run Matlab computation on in our lab (academic). Matlab parallel computing toolbox licence allows up to 12 local workers so we are aiming at a 12 core server with 4GB memory per core (total of 48gb). The system will have an SSD for the OS and a raid-5 (4x2tb) for data. I looked around and found a (relatively) cheap vendor, Silicon Mechanics, that offers a system to our liking (specs below) for $6732. However, buying the components from newegg cost only $4464! The difference is $2268 which is 50% of the base cost. If buying from a company can be thought of as a sort of insurance, basically my premiums are of 50% of the base cost which to me sounds like a lot. Of course any downtime is bad, but the work is not "mission critical", i.e. if it takes a few days to fix it when it breaks its no the end of the world. If it takes weeks to months then its a problem. If it breaks 2-3 times in 3 years, not too bad. If it breaks every month not good. In term of build experience, I set up a linux cluster in grad school (from existing computers) and I build my home pcs but I never built a server before. The server components I'm thinking about: 1 x SUPERMICRO SYS-7046T-6F 4U Tower Server Barebone Dual LGA 1366 Intel 5520 DDR3 1333/1066/800 ($1,050) 12 x Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) ECC Unbuffered Server Memory ($420) 2 x Intel Xeon E5645 Westmere-EP 2.4GHz LGA 1366 80W Six-Core ($1,116) 4 x Seagate Constellation ES 2TB 7200 RPM SATA 6.0Gb/s 3.5" ($1,040) 1 x SAMSUNG Internal DVD Writer Black SATA ($20) 1 x Intel 520 Series 2.5" 180GB SATA III MLC SSD $300 1 x LSI LSI00281 PCI-Express 2.0 x8 MD2 Low profile SATA / SAS MegaRAID SAS 9260CV-4i Controller Card, $695

• Moving Microsoft Exchange server to the private network.

  - by Alexey Shatygin

  In one of the offices, we have a 50-computers network, which had only one server machine: Windows 2003 Server Microsoft ISA Server Microsoft Exchange 2003 This server worked as a gateway (proxy server), mail server, file server, firewall and domain controller. It had two network interfaces, one for WAN (let's say 222.222.222.222) and one for LAN (192.168.1.1). I set up a Linux box to be the gateway (without a proxy), so the Linux box now has the following interfaces: 222.222.222.222 (our external IP, we removed it from the Windows machine) and 192.168.1.100 (internal IP), but we need to keep the old Windows server as a mail server and a proxy for some of our users, until we prepare another Linux machine for that, so I need the mail server on that machine to be available from the Internet. I set up iptables rules to redirect all the incoming connections on the 25th and 110th ports of our external IP to 192.168.1.1:25 and 192.168.1.1:110 and when I try to telnet our SMTP service telnet 222.222.222.222 25 I get the greetings from our windows server's (192.168.1.1) SMTP service, and that's works fine. But when I telnet POP3 service telnet 222.222.222.222 110 I only get the blank black screen and the connection seem to disappear if I press any button. I've checked the ISA rules - everything seems to be the same for 110th and 25th ports. When I telnet on 110th ports of our Windows server from our new gateway machine like this: telnet 192.168.1.1 110 I get the acces to it's POP3 service: +OK Microsoft Exchange Server 2003 POP3 server version 6.5.7638.1 (...) ready. What sould I do, to make the POP3 service available through our new gateway?

• Hung Java JVM failing to respond to kill -3

  - by Hans

  I have a Java VM that is hanging "randomly". I quote the randomly bit, because there is obviously a reason that the VM is hanging, but the hang does not occur periodically. We have the same software running in different customer environments and in those environments the JVM is not hanging. In the process of attempting to troubleshoot the hang the process exists with zero CPU utilization. I then attempt to execute kill -3 and the kill command hangs. No JVM Thread Dump is produced. I have spent time instrumenting the code to periodically log the thread stack traces hoping to catch the JVM in a state that would indicate where the issue lies, but so far this attempt has not born much fruit. Unfortunately I have not been able to reproduce this issue in my lab environment so I am limited by what can be done at the Customer site. The OS's in question are Red Hat Enterprise 5.4 and SUSE 10 running java version 1.6.0_05-b13 Has anyone had this problem? Any ideas on why kill -3 is failing to produce a Java Thread Dump? Thanks!

• Dell laptop keyboard doesn't work

  - by Tam

  I'm trying to fix my in-laws laptop, it's a Dell Studio 1745 that's running Windows 7 64 bit. The problem is that most of the keys on the keyboard do not work. The function keys work and the caps lock and numpad keys work, but no other keys do. If I hit the F2 key enough times when starting up, I can get to the BIOS, but after that even the function keys stop working. If I let it go all the way to the Windows login screen, I can see that the caps lock and num lock work - little images on screen actually appear, but they don't toggle the state of the key, i.e.,capslock is always off, numlock is always off. Using the fn+function combo works, so changing the brightness, etc. works fine. I'm stumped. I've tried disconnecting power and battery and leaving it for an hour or so before starting up but that hasn't helped either. Also - this might be a red herring - the touchpad is failing as well, the MS Device Manager says that it's failing with status 10, "unable to start device"

• Help, my CentOS servers keep going down , No route to host after a random uptime

  - by user249071

  Hello , I have a couple of Centos linux servers, that have a very simple task, they run nginx + fastcgi for php , and some NFS mounts between them, readonly They have some RPC commands to start some downloading processes with wget, nothing fancy , from a main server, but their behavior is very unstable, they simply go down, we tried to monitor ram , processor usage, even network connections, they don't load up so much, max network connections up to... 250 max, 15% processor usage and memory , well, doesn't even fill up, 2.5GB from 8GB max , I have no ideea why can a linux server go down like that, they aren't even public servers, no domain names installed no public serving, for sites. The only thing that I've discovered was that if i didn't restart the network service every couple of hours or so... the servers were becoming very slow, starting apps very slow, but not repoting a high usage of resources...Maybe Centos doesn't free the timeout connections, or something like that...It's based on Red Hat right? I'm not a linux expert , but I'm sure that there are a few guys out there that can easily have an answer to this , or even have some leads to what i can do ... I haven't installed snort, or other things to view if we have some DOS attacks, still the scheduled script that restarts the network each hour should put the system back online, and it doesn't.... Thank you in advance

• External Dell Display doesn't work with MacBook Pro (2011) after Thunderbolt Firmware Update (1.0 and 1.2)

  - by tom

  Today two Thunderbolt Firmware Updates (1.0 and 1.2) became available for my MacBook Pro (Early 2011). After installing both, my external monitor, a Dell U2713HM, does no longer work. The system detects the display, but the display shows only black. An Apple Thunderbolt display works fine and a MacBook Air can use the Dell monitor without problems. My MacBook Pro can use the Dell monitor just fine when I boot from a USB stick. Therefore, clearly the Thunderbolt Firmware Update seems to be the problem. Does anyone have the same problem? Any solutions or workarounds? I guess there is no way to remove a Thunderbolt Firmware Update once it's installed, right? Update 24.10.2013: Is there no one else with this problem? In the meantime I tried three different cables – none worked. My colleague with the same generation MacBook Pro also can't use my display after installing the firmware update. All colleagues with MacBook Airs and newer MacBook Pros (all didn't receive the firmware update) can use the display. Update 29.10.2013: Wow, ok today my new MacBook Pro Retina 13' (Late 2013) arrived. Guess what, I cannot use the display with it. Only HDMI works – not with the full resolution.

• I need to preserve a tape using symantec backup exec. I'm aving trouble doing so

  - by MrVimes

  Please forgive me if this is the wrong stack exchange site. Please suggest which one I should post this to if it is. There's an automatic tape machine running in a remote location, with software (symantec backup exec 11d) Recently one of the servers being backed up had problems with its raid controller, so one of the drives has become invisible. I need to preserve the last good backup of that drive so I am trying to replace the tape with the most recent backup of that drive on it with one of the scratch tapes (blank tapes) present in the machine. I've tried the following... Associate the blank media with the media set in question (Wednesday) For the existing media (the tape with the data I want to keep) I click 'move to vault' and move it to the offline vault. I associate it with something other than 'Wednesday' (a media set called 'keep data infinitely...') I then do an inventory on that slot. The above steps I'm led to believe are supposed to put the fresh tape in the slot that had the tape I want to keep in it. But it just keeps showing up as containing the tape I want to keep after the inventory. (after refreshing the device tree) I am a complete newbie with this software. Can you tell me what I'm doing wrong, and/or tell me how to acheive my desired goal Edit: Just want to point out that I did try to get help directly from symantec with this, but having jumped through countless hoops to create an account and create a support ticket my progress was halted by requiring something called a 'tecnical contact id' at the final step with no explanation of what it is or how to get one.

• Configuring nginx to check for hard files in only a few directories,

  - by Evan Carroll

  For a node.js project I'm doing, I have a tree like this. +-- public ¦   +-- components ¦   +-- css ¦   +-- img +-- routes +-- views Essentially, I have the root to be set to public. I want all requests destined to /components/ /css/ /img/ To check to see if their appropriate destinations exist on disk. However, I don't want requests to other directories to even run an IO operation, /foo/asdf /bar /baz/index.html None of those should result in the disk being touched. I have a stansa that does the proxy to node.js, location @proxy { internal; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:3030; proxy_redirect off; } I just would like to know how to arrange this. My problem would be easily solved if try_files took a single argument, but it always wants a file first. location /components/ { try_files $uri, @proxy } location /css/ { try_files $uri, @proxy } location /img/ { try_files $uri, @proxy } However, there is nothing that I can find that will give me, location / { try_files @proxy } How do I get the effect I want?

• Synchronize Dreamweaver over an SSH tunnel using an SFTP connection

  - by Aeo

  Maybe... Just maybe... I'm asking too much here. Maybe I'm even barking up the wrong tree. I'm looking to essentially have Dreamweaver establish an SSH tunnel to one machine, and then use that connection to synchronize a site that is on another machine entirely. Now for some details: We've got two connections here at work. We've got our office connection for day to day business, and then we've got some fancy connection hosting our web servers upstairs. For the most part they've been mutually exclusive until recently. We had been establishing an SFTP connection to synchronize our web sites by going out over the office connection to the web and coming back in over the fancy connection to our servers upstairs. Recently -ish, we established a LAN connection to one of our servers that makes a pleasant change in VNC connection quality. Thanks to Vinagre, this makes it really easy to connect to any of our servers over this LAN connection via SSH tunnel for VNC. However, in spite of that new addition of a LAN connection, we still synchronize over the 'net. Out the office connection and in on the fancy one upstairs. I'm looking to change this. I'd like to get Dreamweaver to first tunnel over our LAN connection to the servers, and then go from there to whatever connection it needs to. Am I asking too much? The current set up: Dreamweaver is installed on Windows XP which is running within VirtualBox on top of Ubuntu 10.10. The network connection for VirtualBox is currently made in NAT mode, but could easily be switched to a Bridged Connection should it need be. The LAN connection is to 1 of 5 servers running CentOS 5.

• Make reading more comfortable for the eyes

  - by Shiki

  First, I read the topics about displays. Sadly the "BenQ FP241WZ" is a no go, for ~715 eur it's way too much. I would need some ideas about how could I make reading less tiring. Basically I didn't have this problem back then. But now, I'm reading some books, and also, have to read a lot a day. (A LOT). I look like some hardcore 0-24 gamer when I "finish" :). Think about things like.. background color (like I read 'dark yellow' color + black tint helps), font size, fonts (!) cleartype settings (should be off?) and so on. Display: BenQ E2200 HD (yeah cheap, eek, etc. Poor-man's LCD. :)) My CRT display is far away at the minute. So that is out of question. Also, my ThinkPad is here (T500), but I don't know about it's display. It comes with 1280x800 resolution and that's all I know (you can search back from that the FRU number, but I couldn't find it now). What could I do? (Or basically everyone in such a situation?)

• PC won't boot from IDE HDD when SATA data drive connected

  - by Kevin

  I have an old Pentium 4 system running XP. The machine is set up as an HTPC. It was set up and running well with 1 SATA drive as a boot drive, another SATA drive to store TV recordings, and an IDE drive to store more recordings. Last week the original boot drive (a SATA drive) failed. The BIOS would no longer recognize it. I had a disused IDE drive hanging around that was large enough for the OS, so I reformatted it and installed XP on it. Now the system will only boot if I do not connect the remaining healthy SATA data drive. All three drives are recognized by the BIOS, and I have set the boot order so that the IDE drive with XP on it has top priority, but after the BIOS recognizes the drives, etc. I just get a black screen. I know the SATA drive is functional, because if I hot plug the drive AFTER the system is booted (I know I'm not supposed to do this), I can go into the control panels and mount the drive, and see all the files and folders on it in Windows Explorer. Any suggestions on what is going on and how to fix it? Many thanks.

• EC2 AMI won't boot after edit

  - by Eric Lars0n

  I did something stupid, I got a new laptop and copied everything over to the new one, then wiped the old one clean. Then I realized that I forgot to copy the private key out of .ssh that I use to connect to my AWS EBS backed instance. So I can't log in to my custom AMI. So I created a new Volume from the Snapshot of the AMI, then started up a public instance and attached the Volume to it, edit the sshd_config to allow for password log in. Unmounted the volume, detached it, made a snapshot of it, then made a new AMI from the snapshot. The new AMI launches, but never passes the Status Checks and is not reachable. What am I doing wrong? Or alternatively how can I fix my problem?

• Ubuntu 10.04 on virtualbox gives error: Target filesystem doesn't have /sbin/init \ No init found. Try passing init= bootarg

  - by Philip

  I'm a linux newbie and the only reason I have it installed is so I can stop having Windows incompatibility issues with Ruby on Rails. Having said that, it sure has been nice, and much faster, and I don't think I'll be doing any Winrails stuff anytime soon. So I created a virtualmachine using virtualbox and have had ubuntu on it for the last 3 weeks. Recently ubuntu asked if it could update a few things, I clicked 'ok'. Now it won't boot and I get this error: *mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory ... Target filesystem doesn't have /sbin/init. No init found. Try passing init= bootarg BusyBox v1.13.3... (initramfs) _ * So I cruised the forums and there are a variety of solutions, but they all have to do with booting from the live cd. (which I assume is the ISO image I used to install ubuntu in the first place). But when I boot from that CD, it just hangs on the ubuntu screen, and the little dots keep cycling white to red, but it hung there for an hour so I think it was stuck. Not sure what I can do; can I do anything from the busybox shell (or whatever that is) to fix things? The thing is, it took about 10 hours to get everything the way I needed with all the gems and whatnot. And I didn't really write down what I tweaked, and I'm middle aged, so all that information has leaked out by now and I don't want to do it again. I'd really like to repair my existing install. One question you might have is, is there something wrong with the ISO? I don't think so, because I made a new virtual machine and used that same iso file to install a fresh ubuntu. Any help much appreciated. Phil

• Installed Windows 7 Ultimate on D Drive and previous Windows 7 Enterprise on C Drive has stopped starting up

  - by teenup

  Please please help! I have installed Windows 7 Ultimate on same hard drive on D Drive on my laptop and the previous Windows 7 Enterprise which was installed on C Drive is not booting up now. When I turn on my laptop, I see two Windows 7 on the screen, when I select newer one, it starts, but when I select older one which is Enterprise edition, system won't start and I get the DOS black screen with this error message: Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: Insert your Windows installation disc and restart your computer. Choose your language settings, and then click "Next." Click "repair your computer." Info: The boot selection failed because a required device is inaccessible. I notice that when I run the newer OS installed, the previous OS's drive (Which is D: now instead of C:) has become unusable and when I double click it, it asks me to format the drive. The data, that I had on my D Drive (Which is now C Drive for new OS), I had copied it to a network path and it is available. It was containing Windows 7 Users folder which I copied at that time when installing new windows. I have copied that Users folder again to the new OS's C Drive thinking it would run again, but of no use. Please please please...if someone can help...It is extremely required for me. Thanks a lot in advance.

• P2V Wouldn't Boot, Rebuilt initrd, Need to Clean Up

  - by Mike Soule

  We have a CentOS 5.4 server (build 2.6.18-164.el5xen). We went to P2V this server so we can have redundancy, the physical only has one PSU. The P2V only completed 99% of the way, we have a VMWare ticket opened, but they marked the ticket as low priority. I was able to boot into a rescue disc of Red Hat 5.4 and rebuild the initrd with the help of this blog post. Now the only issue is the original server had a modified initrd, which was also from a different OS build and made by an outside provider. We do not have a document outlining modifications. My question is, is it at all possible to copy the initrd off of the physical server and replace it on the virtual and some how have the virtual machine boot? Thanks for any input. Edit: I copied the initrd img from the physical and it recreated the original issue. Here is a screen capture of the error. http://i.imgur.com/MqC73.jpg Edit2: echo Scanning logical volumes lvm vgscan --ignorelockingfailure echo Activating logical volumes lvm vgchange -ay --ignorelockingfailure VolGroup00 resume /dev/VolGroup00/LogVol01 echo Creating root device. mkrootdev -t ext3 -o defaults,ro /dev/VolGroup00/LogVol00 echo Mounting root filesystem. mount /sysroot

• Opera's problem with magnet-links

  - by Dmitriy Matveev

  I've encountered following problem while using Opera web browser: When I click on a magnet link on some web page like magnet:?xt=urn:tree:tiger:CXW6MJFRNOEFU2STCBWWOIYZLVCR2FTR37SQCXY&xl=352342016&dn=ER%20-%207x16%20-%20Witch%20Hunt.avi Opera is asking me if I want to open that link with my DC++ client. If I click 'Yes' button then my DC++ client is correctly "opening" the clicked magnet link and performing some action on it. There is also an option "Do not show this dialog again" in Opera's dialog, but it doesn't seem to be working correctly. If I check that option before answering 'Yes' and then click on other magnet link of the same kind the Opera will again ask me about how to open new link. I haven't found protocol association in 'Control Panel Default Programs Set Associations' part of my Windows Vista settings, but if I paste magnet link in "Run" dialog then Vista will handle that link perfectly. I've tried to find out how to manually set protocol association in Opera and found 'Programs' page of browser's advanced settings. There I discovered that instead of storing protocol to application associations Opera tries to store per-link associations (There are several entries with exact links as they was on web page as value of protocol field). If I click on the links which are already stored in Opera's protocols associations browser will ask me about them again. I haven't found any information on how to resolve this problem on the internet, maybe someone on this site will be able to help me.

• MySQL fault linked to windows shutdown failure?

  - by Roy

  As far as i understand my computer is experiencing a strange coincidence (hopefully it isn't and somebody can enlighten me). Basically i shut down my laptop (Windows 7) (at 17.20, today, to be precise) successfully (and so also did XAMPP and its included components). However upon starting my laptop up again in the last hour i noticed that the MySQL module service in my xampp control panel was not coming on (just a big red tick; incidentally everything else was working fine). Now, i had the exact same problem about two weeks ago, whereby i just reinstalled xampp and got it working again. But rather than doing this straight away i thought i would just restart my laptop first. However it won't restart (or shut down first) to be precise now. I can remember Windows wasn't shutting down properly the last time it happened (about two weeks ago). Just wondered if this coincidence pointed to any specific diagnostic as regards the problem with MYSQL? If so i would appreciate greatly any help. Otherwise sorry for wasting your time.
