• Fix bad superblock on logical partition

  - by Chris

  I was following http://www.howtoforge.com/linux_resi...xt3_partitions and when i reboot and run: root@Microknoppix:/home/knoppix# fsck -n /dev/sda7 fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) fsck.ext2: Superblock invalid, trying backup blocks... fsck.ext2: Bad magic number in super-block while trying to open /dev/sda7 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> so i ran e2fsck with all the block numbers that you need (forget exactly what tool i used to find where the superblocks are hidden) no dice then i ran testdisk and had it look for the superblock, no results anyone have any ideas? fdisk -l for reference: root@Microknoppix:/home/knoppix# fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x97646c29 Device Boot Start End Blocks Id System /dev/sda1 1 64 512000 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 64 38912 312046593 f W95 Ext'd (LBA) /dev/sda5 64 326 2104320 82 Linux swap / Solaris /dev/sda6 * 327 2938 20972544 83 Linux /dev/sda7 2938 38912 288968672+ 83 Linux To be honest it looks like I lost it... Next step if that happens is to dump the partition to an image file and hope i can find or write some software to parse through the data looking for known file headers, i think.

• Cut (smart edit) .mts (AVCHD Progressive) files un Ubuntu Lucid

  - by pts

  I have a bunch of .mts files containing AVCHD Progressive video recorded by a Panasonic camera, and I need software on Ubuntu Lucid with which I can remove the boring parts, and concatenate the interesting parts, all this without reencoding the video stream. It's OK for me to cut at keyframe boundary. If Avidemux was able to open the files, it would take about 60 hours of work for me to cut the files. (At least that was it last time I tried with similar videos, but of a file format supported by Avidemux.) So I need a fast, powerful and stable video editor, because I don't want that 60 hours of work go up to 240 or even 480 hours just because the tool is too slow or unstable or has a terrible UI. I've tried Avidemux 2.5.5 and 2.5.6, but they crash trying to open such a file, even if I convert the file to .avi first using mencoder -oac copy -ovc copy. mplayer can play the files. I've tried Avidemux 2.6.0, which can open the file, but it cannot jump to the previous or next keyframe etc. (if I make it jump to the next keyframe, and then to the previous keyframe, it doesn't end up at the original keyframe, sometimes displays an error etc.). Also I'm not sure if Avidemux 2.6.x would let me save the result without reencoding. I've tried Kdenlive 0.7.7.1, but playback is very choppy, and it cannot play audio at all (complaining that SDL cannot find the device; but many other programs on the system can play audio). It would be a pain to work with. I've tried converting the .mts file to .mkv using ffmpeg -i input.mts -vcodec copy -sameq -acodec copy -f matroska output.mkv, but that caused too much visible distortions in the video in both mplayer and Avidemux. I've tried converting the .mts file with TsRemux.exe, but Avidemux 2.5.x still can't open that file. Is there another program to cut and concatenate the files? Is there a preprocessor which would create a file (without reencoding the video) on which Avidemux wouldn't crash?

• Why do fonts sometimes look "fat" on Mac OS X?

  - by jtimberman

  Sometimes when resuming from suspend, the fonts in Mac OS X look "fatter" than normal. Unfortunately right now I can't get my Macbook Pro to exhibit the "normal" behavior for comparison, it has been abnormal yesterday and today. If I can get screenshots of what I think is 'normal', I'll add them. "Fixing" this has been random. I use an external monitor, and sometimes unplugging it and plugging back in, or even turning it off and back on has worked. Sometimes with the display attached (or not) detecting displays works. Sometimes logging out or rebooting entirely is what it takes. Displays used: Macbook Pro 15" built-in display Dell 27" LCD (2009 model) Software where I see this happen, at least most noticably: Firefox (screenshots below) iTerm Things MacIrssi (screenshots below) I am using Mac OS X 10.5.8. "Abnormal" view from MacIrssi with Inconsolata 16 pt. image full size "Abnormal" view from Firefox. Finally got it to switch back, though after resuming from suspend its back to "fat" :-(. image full size And 'normal' in Firefox:

• MS Excel 2010 - Using DSN + 32 bit drivers

  - by Kristiaan

  I need some advice as im running into a problem and so far i have been unable to find a solution. We have a set of reports developed in MS Excel that use DSN file to connect to data sources to retrieve data, these work fine on 32 / 64bit systems, however we are moving to a terminal server environment using windows 2008 R2 64Bit. The reports fail to run using the DSN's within this environment if we only have the 32bit drivers installed and configured in the ODBC settings, the minute we install the 64Bit drivers the software works. Is there a way / Method of getting Excel or the DSN file to NOT use the 64Bit driver, but force it to use the 32bit driver. ANSWERED - But due to low user score i cannot "answer" my own question... Sadly there is no way to-do what i want to-do, without a lot of very nasty and not 100% perfect reg hacks. If you need to access 32bit ODBC data sources the application in question has to be 32Bit. here is a link to just one forum post i found relating to this type of problem, it appears the only way i would be able to accomplish this is to remove the 64bit version of office and install the 32bit version instead of it. http://social.msdn.microsoft.com/Forums/en-US/accessdev/thread/5108f337-f06a-4518-afe3-d3c1abd040ef/

• Windows 7 Printing Issue

  - by Adrian Godong

  I am using Windows 7 RTM x64. From Control Panel Devices and Printers, I have three printers listed; Fax, XPS Writer, and a Lexmark. I can print a test page through the printer properties with no problem. I can print a text file from Notepad with no problem. I can't print from Safari. When I press Ctrl+P, it displays the Print dialog, press OK and nothing happened. I can't print from Adobe Reader. When I press Ctrl+P, it complains that it there is no printer installed. I can't print from Office applications. When I press Ctrl+P, it crashes immediately. Running Office Diagnostics does not help. I can't print from IE8. When I press Ctrl+P, it displays the Print dialog, complains that I have to select a printer from the list, selected any of the three printers, the Print button is disabled. Any help? Update (01/11/2009): The default printer is the Lexmark. I'm testing on this one as well. I was about to reinstall Office (as this is the first application that has the problem), but then I tried other, some behave similarly but not identical (maybe caused by different printing implementation). On those applications that is able to display printer selection dialog, I tried the Lexmark and XPS. Neither printed anything (paper for Lexmark, file for XPS). Update (01/12/2009): It seems that my Windows installation is botched. A colleague have similar hardware/software combination (it's the same workstation model and Windows 7 x64) and his can print perfectly fine. I tried adding the printer from his share, no joy. I can test print from the printer property, I can print from Notepad, but not from any other application.

• Why does Windows 7 have three system partitions?

  - by Ben

  I am using Windows 7, and I wanted to make a System image (using Windows 7), but Windows 7 checked three partitions as System (100 MB + C (install partition) + D (my partition for my files, all programs are installed at C)). I don't want to backup my D partition, but that is not really the point. I don't want Windows messing with my other partitions and making them system. Is there a way to limit Windows 7 just to partition C (install partition)? If there is no way to stop Windows from making other partitions system, can I at least delete the files that make partition D system? PS: All these three partitions are on one physical disk, partitions from other disks aren't treated as System. FACTS: desktop PC, no OEM partitions, I personally have installed Windows 7 (many times) on the C partition. Why is my D partition checked as System partition when I try to create a System Image (using Windows 7 Ultimate built in tool), even though Windows (and all the software) are installed on the C partition? Is there a way to make D "normal" or non-system partition? Here is a picture of how it looks like if I try to create a system image. Once again, why is D also a system partition?

• How can I allow the Xbox 360 to browse movies on a network drive?

  - by Roger

  I've always been able to stream movies stored on my Windows 7 computer's local hard drive to the Xbox 360 with no problems. A few weeks ago, though, I got a Seagate Dockstar NAS device and moved my movies to it. Ever since then, I can't seem them in the Xbox. I've tried several different things. When I try to add the mapped drive to the Media Player library, it says that it can't share the files. (I don't have any security on the NAS drive). I've tried creating a symlink to a local drive, but that doesn't help. Neither does adding the UNC path directly. The Dockstar seems to have its own Xbox share capability, but it doesn't respect my folder structure - it brings over every video file on the drive in a single list, including several hundred home videos that aren't playable on the Xbox. Is there any way to use Media Player (or the Zune software) to share files stored on a NAS drive? Barring this, is there a lightweight, free server that will allow me to share these files while maintaining my folder structure?

• Does the same lame settings (--alt-preset standard) have differrent names?

  - by erikric

  I've always used windows, and therefore EAC to rip my CDs, but since I've started using Ubuntu more often, I decided to try to rip some albums there. I ended up using k3b (since I found it in the Ubuntu Software center. Tried to install RubyRipper first, but when 'sudo apt-get install ' or UDC fails, a Windows user like me is lost) The real question here is about the settings for the lame encoder. I'm used to just writing --alt-preset standard, and everything works like a charm, but the default in k3b look like this: lame -r --bitwidth 16 --little-endian -s 44.1 -h --tt %t --ta %a --tl %m --ty %y --tc %c --tn %n - %f I assume these are some sensible lame settings, and not a malicious perl script (although it looks like it). It seems to me like some of these ought to be there, and that I can not overwrite the whole thing with my good ol' --alt-preset. So, the question is do I need to replace anything, or is -h the same as old --alt-preset? Is it a difference between '--preset standard' and '--alt-preset standard'? And are those the same as -V 2?

• ssd firmware, linux: updating large batch of drives

  - by wryfi

  I was recently hit with a fatal firmware bug that affected dozens of Crucial SSDs deployed in my datacenter. Many of the affected machines use LSI or other proprietary SAS controllers, which Crucial's bootable ISO does not recognize. None of the affected machines has a Windows license. The story is roughly similar for other SSD mfrs, including Samsung and Intel. To resolve this issue, I was forced to stop each machine, remove the affected SSD, remove the SSD from its hotswap caddy, install it temporarily into my ThinkPad, flash the firmware, reverse, rinse, repeat. It took the better part of a day to get through all the affected devices. I am looking for hardware, software, and/or purchasing strategies to ease this pain, as SSD firmware bugs seem inevitable, and our SSD footprint is growing. My first thought is to get a laptop with eSATA and one of these cables (http://www.newegg.com/Product/Product.aspx?Item=N82E16812311004). That should at least make it so I don't have to remove the drives from their caddies. Surely others have run into this. Any novel solutions?

• Avoid "privacy pitfalls" in Windows and Linux?

  - by Somebody still uses you MS-DOS

  I have a Windows and a Linux machine. In Windows, everytime I visit a site, a lot of cache/history files are created on my machine. I setup my Firefox to don't save anything. ...but Windows saves a lot of "temp" files, some strange files I opened in registry (like video names). Each video I open in VLC is shown in "Last shown videos". In windows, all files opened can be found at "Recent opened files" as well. A lot of these privacy configurations can be tweaked (VLC and "Recent opened files" in Windows) - it's a PITA doing it individually, but it's possible - but there isn't a guide to these "internal" privacy traces that are left on Windows installation. In Linux, I just know there are these problems in app level (like VLC). My question is: is there a complete guide to avoid undesirable traces of what I did/watch/used in my Windows machine? (Delete everytime the PC is restarted, or even avoiding recording these info at all) Is there a website with configuration guides to different types of software? I would like to know about Linux privacy pitfalls as well.

• Samsung laptop randomly shuts down

  - by Dmatig

  I've rewritten this question because it turned into an indecipherable mess. I have a Samsung R560 laptop that is overheating, and shutting itself down under load consistantly. Thank you quickcel for reccomending me Speedfan to monitor my temps. Here they are (Load / Idle): (Ignore "Temp1 and Temp2", whatever sensors they are they'd always random, pretty sure they're broke). The load temperature is after just 5 minites of playing Fallout 3 - another 5 minutes and it (the GPU - 9600M GS) consistantly breaches the mid 90's then shuts down, so it's hard to get a good picture of it. I'm looking for some solution or way to decrease these temperatures, because they seem far too high even idle. I've tried: Opening up the case and clearing of all dust with compressed air. Updating drivers for my Graphics card Have purchased and am using a notebook cooler I don't want to: Undervolt / underclock (defeats the point of having a more expensive card) Use lower power / performance settings (again, i might as well have bought something cheaper) Is there anything else i can try (software or inexpensive hardware) that can help me fix this? Has anybody had a Samsung laptop and knows if this can be sorted under my warranty, and the turnaround time of sending it off (UK?)(it has always ran hotter than it should, but now at 6 months old is getting hot enough to power off)

• How do you notice that the batteries of you wireless mouse are dying out?

  - by hkBattousai

  I have a Logitech M705 wireless mouse. I'm first time using a wireless mouse, so I don't have much experience with the hardware features and behavior. It is rated that it runs for 3 years with the same batteries. I think this "3 year" rating is calculated for a very low usage and activity; like 2 hours a day. I'm using it for about 12 hours a day, so I expect it to run out of batteries in a much shorter time in my case. I have been using it for about half a year. Recently (for the last two weeks), it started to make some peculiar behavior when clicking and drafging objects. - When I click something, it sometimes double click it. - When I drag something from one place to another (or selecting some text), it sometimes drops the object in the halfway (when selecting text, the text which had selected up to that time becomes unselected and it starts to select the rest of the text from that moment), but it goes on being in the "left-button-pressed" state. It is like, the pressed button switches to "unpressed" state for a moment, then returns back to the "pressed" state. When one of these faults occur, it occurs several times sequentially. There is no problem in pointer movement, scrolling or right-clicking. Since the batteries last for a very long time for this device, I don't expect it to stop working in an instance. I expect it to give these kind of syndromes of a time period. My question is; Is this how batteries run out for a wireless mouse? Or, is this another kind of hardware/software problem?

• Determine wifi capabilities of Windows box (with WSUS install rules)

  - by Hagen von Eitzen

  I need to determine if a computer is in fact a laptop with wifi capabilities (with emphasis on wifi rather than laptop). More precisely, I want to distribute a piece of software I wrote via WSUS and Local Update Publisher to those clients. To this end, I want to create appropriate "Package installable rules", that is simple rule used bay the Windows Update Service on the client to decide beforehand whether or not an update/installation package is applicable. Typically, such "installabel rules" are logical combinations of rules of type "File exists", "Registry Key exists", "WMI Query", "MSI Product Installed", so I'd prefer one of those methods. The method I hope someone here can help me find should work with Win 7/Vista, preferably also with XP. My guess is that WMI query is the way to go, but I have little experience in that. I have found that one can e.g. query for EnclosureType and that might detect a laptop. However, I would be much happier if an actually available wifi interface would be detected. Does anyone have an idea how to approach this? If there is anything you need me to clarify, don't hesitate to comment.

• Preferred mail system/server for a company?

  - by Trevoke

  Say you are responsible for setting up an email solution at a company. Which would be your choice? I know of the following options, but many of them not well: Gordano Mail System Exchange Exim Postfix Qmail Zimbra For having used it a little over two years, I really, really like Gordano Mail System. They offer a whole bunch of things, like calendaring, anti-spam, anti-virus, extremely complete and filterable logging options, aliases, a customizable webmail interface... And their software can be installed on both a Windows or Linux OS. In addition, their support is top-notch, their knowledgebase comprehensive (and, I will admit with a touch of pride, I have contributed, with my questions, to the addition of a few articles in there). Of course, they're not free, which can be a problem, but they're not Exchange, and they do offer pretty much everything that Exchange offers -- which is great if you want to stay away from that, but need all the features. Although, if you need a Blackberry Exchange Server, or something similar, I'm not sure what you should go for. So.. What would your choice be? Why? I've never played with a more DIY email solution, but I'm sure many people here have and wouldn't trade their setup for the world :)

• hp DL380 G4 won't boot with disk plugged into front USB

  - by Kev

  We outgrew a few older external USB backup drives, and purchased WD My Passport 1 TB USB 3.0 drives to replace them. When they are plugged into the front of our G4, it will blink forever after the BIOS (which is current, BTW) and never boot, even though the USB disks are not "bootable" per se. Our old drives did not exhibit this behaviour (so I don't think it's this type of issue that I've read about other servers.) The old drives were USB 2.0, but this shouldn't make a difference, AFAICT--the specs say all of the G4's USB ports are the same, 2.0, anyway, so I'm not sure how one port would handle a USB 3.0 device better than another. If we plug the new drives in one of the back slots, it boots fine. What's the cause? My concern is that the front USB port, and possibly the motherboard, might be starting to die. (We are experiencing other strange issues with them, or were initially, like intermittent file permissions errors despite wide-open ACL on these local drives, but some serverfault users have me convinced they may be coincidental software/security related issues.)

• Install VirtualBox on Ubuntu 12.04.1 (on [Samsung] Chromebook)

  - by iphonedev7

  I have dual booted Ubuntu Linux 12.04.1 LTS on my Samsung Series 5 ChromeBook, and am trying to run/install Oracle VirtualBox (from the generic .run file downloaded from their website). However, every time I try to run it (as root from the command line), it gives me the following error occurs: Please install the build and header files for your current Linux kernel. The current kernel version is 3.4.0 Problems were found which would prevent VirtualBox from installing. I have tried the version from the Software Center, as well as the command line installation, both of which gave me errors based on my linux-headers/linux-kernel/linux-[kernel]-image. Here's an error I keep getting (on the command line): First Installation: checking all kernels...

• OpenVZ vs KVM for Linux VMs

  - by Eliasdx

  Hardware: Intel® Core™ i7-920, 12 GB DDR3 RAM, 2 x 1500 GB SATA-II HDD (no SoftRaid because Proxmox developers don't support softraid and they are sure you'll run into problems) Software: Proxmox VE with KVM and OpenVZ support and debian everywhere I want to run multiple Linux VMs on this server. One for a firewall (I want to try pfSense), one for MySQL, one VM for nginx (my stuff) and ~2 VMs with nginx for other people's web sites. I don't think that pfSense will run in an OpenVZ environment but it should run in KVM. The question is if I should setup the other VMs using KVM or OpenVZ. In OpenVZ they should have less overhead for the OS itself but I don't know about the performance. I heard that KVM is more stable but needs more RAM and CPU. I found this diagram showing a OpenVZ setup on the same hardware I'm using. This guy uses an own VM for each and every website which is running on his server. I can't think of any advantage why he's using so many VMs.

• Hosting a server for websites, ftp and random use at home?

  - by Zolomon

  I'm wondering what's the best option for me if I want to move all my hosted websites (from a hosting company) to a server at my own home? Basically, the needs I have are: be able to host websites using PHP/ASP.NET (haven't really decided yet - both would be preferred!) enable FTP so I can create accounts for my family members to access the server for file handling SSH SSL - for secure connections (this is something you have to buy/apply for per domain, not sure if there are any server side settings that have to be made) be able to stream video remote desktop host home-brew applications that can run as services use either MySQl/SQLite/SQL for relational database storage What should I think of before I buy a server? What hardware will I need, what will limit my server? I basically want to learn networking better as I'm a software and web developer but haven't had the resources to acquire any serious toys until now. At the time of writing, most of my websites have 60 visits/day so I don't suspect them to be very demanding. Is there something I haven't thought of that I should have? What OS would you suggest I run? FreeBSD vs Windows Server vs ?

• Unable to Use Bluetooth Mighty Mouse or Wireless Keyboard with Boot Camp

  - by Kristopher Johnson

  I have Windows 7 64-bit running on a MacBook Pro in a Boot Camp partition. I am trying to pair with my Bluetooth Mighty Mouse and Apple wireless keyboard under Windows, but whenever I try to do so, here's what happens: While on the Add a device window, I turn on the mouse or press a key on the keyboard, and the mouse or keyboard shows up in the list of available devices. I click the device and then the Next button, and the window displays Connecting to device... Time passes. Eventually, I get this error message: Adding this device to this computer failed Adding the device failed resulting in an unknown error. The reported error code is 0x80070015. Contact your device manufacturer for assistance. I've run Windows Update and Apple Software Update. I've also tried reinstalling the drivers from the Snow Leopard DVD. The mouse and keyboard both work fine when I boot into Mac OS X. FWIW, after many, many repeated tries, I eventually got it to work. I don't know why. So while my problem is solved, I'd still like to get an "answer" as to why trial-and-error seems to be the only approach. The keyboard, in particular, was hard to get set up. A few times, Windows would apparently recognize it and prompt me to enter the pairing code, but then it would time out after a couple of seconds (not long enough to enter the code). Grrrr.

• Restoring Windows 2008 Server X86 and X64

  - by rihatum

  Restoring Windows 2008 Server (Domain Controller) We are using Backup Exec System Recovery 2010 to Image our DC. Now this software has a feature to convert the backup into a vmware or hyper-v VM I have also used disk2vhd to convert one of our dc's to a vhd and when I connected it into Hyper-V, it booted fine, I can login - BUT :-) As soon as I login, I get the activation error, that change product key, this product key isn't good for this machine etc. Question is : When in a real recovery situation, what would be the procedure to restore it either virtual or onto a physical box but be able to login and change product key etc ? In this scenario its just locked down and I cant' do anything, if this is the case, how would I replicate my production environment via these tools ? Any Ideas ? Will be grateful for some real world examples here. Same thing happens with our exchange backup / test restore either physical or virtual, can login but nothing else. Now we don't have the keys as they are OEM keys and just wondering what will happen in a real scenario, would we be purchasing another KEY or using the OEM key on our new server ? This is a test environment I am trying to create by restoring our backups either into hyper-v or physical test machines. Also, If I build up a machine (Server 2008) in a VM (Hyper-V), How can I restore just the system state backup of my DC into it ? will that give me the activation error too ? even though I would use the TRIAL ISOs provided by Microsoft ? Kind regards

• Windows 7 DVD doesn't boot up, neither does USB. :'(

  - by Manan Shah

  My problem is that i'm not able to install windows 7. Been trying to install this since past 1 week. The methods i've tried are: I have a windows 7 bootable DVD which doesnt boot up. (I've set BIOS to boot from DVD ROM first but it just won't boot from the DVD). Tried to install Windows 7 from the same DVD to a friend's PC and it worked. So the DVD has no issues. I tried to run 'Setup.exe' from within the DVD. The two options pop-up 'Check compatibility' and 'Install now'. On clicking install now, after sometime, an error is encountered with the message 'Windows was unable to create a required installation folder' error code:0x8007000D. I am running Windows XP Professional and there's only one user on the PC which is the Admin, so i do not know why is the setup not getting permissions. I've also uninstalled my antivirus, CD burning software, disabled firewall and disconnected all other devices, but its still the same. I tried to install it from a USB device by making it bootable but that too doesnt work. (Yes the mobo supports booting from the USB). The problem is that XP does not recognize a 'USB' device on boot. Rather it shows this USB stick as a removable 'Hard Drive'. Furthermore, i changed the order of Hard Drive boot to boot from this removable Hard Drive first, it still boots my existing OS. Is there anything else that can be done? Any help would be greatly appreciated. :) Please ask if any other information is required, this post is becomimg increasingly long to add any other details. PS: I want to dual boot windows 7 with my existing XP, but that would be after i manage to run the windows 7 setup in the first place. PPS: Please bare with any 'not-so-technical' terms, i am a beginner with this. Again, thank you for taking the time and trying to help, really appreciate it. :)

• Home Server: storage virtualisation, what to choose?

  - by Huygens

  I'm looking for virtualisation solutions for storage and OS for a home server. A sort of private cloud where I manage the storage space independently of the VM one. This question focus on storage management. (I have another question related to the VM/compute instance management). Here my environement and wishes. Server: HP Proliant MicroServer with 8 GB RAM (AMD Turion dual core with AMD-V technology) with 1 250GB system disk and up to 4 HDD (2 TB) for "data" OS types: only Linux (perhaps a *BSD VM in the future) Linux distributions do not matter, I'm familiar with RHEL, Fedora, Suse, Ubuntu, but any other recommandation will be fine The 4 HDD is going to be a software RAID array, probably RAID 5. storage should be "virtualised/cloudified": easy to extend: if I add a NAS on the network, I can include the NAS space capacity within this storage space as one virtual disk. This can be a NAS, an external HDD or another server. cluster FS or S3 style space or OpenStack block storage? Whatever is easier to manage/maintain and easy to integrate/plug to VM/compute instance. I would prefer free (libre, as in a free speach) and open source tools. But it does not have to be free as in a free beer. Note: the VMs I intend to run on top of this server are one dedicated to backup, one for a "owncloud/dropbox"-like service and perhaps one for media server (hosting video and photos). I'm not sure if traditional VMs or compute instance are the most suitable for this.

• Port 22 is not responding

  - by Emanuele Feliziani

  I'm trying to make the jump to VPS from shared hosting for better performances and greater flexibility, but am stuck with the fact that I can't access the machine via ssh. First of all, the machine is a CentOS 6.3 cPanel x64 with WHM 11.38.0. Sshd is running (it appears in the current running processes). Making a port scan I see that port 22 is not responding. Port 21 is, but I am not able to access the machine via ftp (I think it's a security measure, but I don't know where to disable/enable it). So, I'm stuck in WHM and have no way to access the configuration of the machine, neither via ssh nor with ftp/sftp. When trying to connect with ssh via Terminal I only get this: ssh: connect to host xx.xx.xxx.xxx port 22: Operation timed out I also tried to access with the hostname instead of the IP address and it's the same. There seem to be no firewall in WHM and I have whitelisted my home IP address to access ssh, though there were no restrictions in the first place. I have been wandering through all the settings and options in WHM for several hours now, but can't seem to find anything. Does anybody have a clue as to where I should start investigating? Update: Thanks everyone. It was in fact a matter of firewall. There was a firewall not controlled by the WHM software. I managed to crack into the console from the vps control panel (a terrible, terrible java app that barely took my keyboard input) and disabled the firewall altogether running service iptables stop so that I was able to access the console via ssh with the terminal. Now I will have to set up the firewall again because the command I ran looks like having completely wiped the iptables. Can you recommend any newby-friendly resource where I can learn how to go about this and what should I block? Or should I just go with something like this: http://configserver.com/cp/csf.html ? Thanks again to everyone who helped me out.

• Website hosting from home - IIS6

  - by Paul

  I'm wanting to host a few websites from home, primarily because I'm using some BETA Microsoft software (.NET 4 and EF) and don't want to install it on my production server which is hosted at eukhost.com. Basically, I'm completely new to this sort of thing. So far, here is what I've done: Registered the domain name at namecheap.com (let's call it mydomain.com) Gone to "Nameserver Registration" in the panel and entered my IP address for the NS1 and NS2 records (let's say the IP is 0.0.0.0). Gone to "Domain Name Server Setup" and entered ns1.mydomain.com & ns2.mydomain.com Forwarded requests from port 80 to my internal IP (let's say 192.168.1.254) Created the website in IIS (I'm just testing with a single website so far, so have not created any host header values) Now, if I type in the IP address (http://0.0.0.0) I get the site as expected. However, if I enter http://www.mydomain.com I get an error saying "DNS Error - Cannot find server". I'm aware that there is a service from DynDNS that will automatically change the IP if I have a dynamic address, however my IP has remained static since I installed the ISP (since October) so I don't need this. Is there any way that I can get the DNS to work just by configuring IIS or something in Windows? I don't really want to have to pay for any 3rd party service. Thanks,

• Delay init from starting a service for a period of time?

  - by Matthew

  I am trying to get a rudimentary NFS server up and running. Right now the server is configured as an NFS server due to a workaround for a vendor issue not supporting direct attached clustered storage, which we are trying to get them to resolve. The vendor software is Splunk. The splunk feature we are using requires files be located on shared storage (which for us is /mnt/nfs until they support a real clustered filesystem). Currently the server has a GFS2 filesystem mounted at bootup (it is the only server with the filesystem actively mounted so there should be no problems with locking). We went with GFS2 so switching over to a clustered filesystem is easy should the vendor begin supporting it. NFS is configured to mount that filesystem at /mnt/nfs, which the splunk installation than sees. Splunk is configured to find it's configuration files in /mnt/nfs. However, I am running into a problem where the splunk daemon starts before nfs is finished loading, and because it sees nothing at /mnt/nfs it starts creating files there, and then when the files disappear (nfs finishes mounting the share), splunk craps out. Splunk is set to run at runlevel 3, S90. NFS is set at runlevels 2-5, S60. Is there any way to delay the startup of the splunk process further?
