• Creating ISO image of NTFS partition in Ubuntu

  - by Pappai

  Hi, I have a system that has to be formatted often because of the specific use of it (Use it in internet cafe). I have to install the drivers and apps each time. That is a time consuming and cumbersom task for me. I want to install windows, drivers, apps etc. once and create a backup of the entire C:\ drive, and keep it in a linux partition so that I can restore the OS with all the apps & drivers ready to go! I have ubuntu live CD with me and I have created a linux partition (ext4) in the HDD. My question is: How can I create an ISO image of the C:\ drive (ntfs disk) in Ubuntu and store it in the linux partition?

• Thunderbird 11.0.1 reply address issues

  - by hardlywired

  I'm running Thunderbird 11.0.1 under Linux Mint 12 for all my email addresses (all IMAP). I have recently found that when I reply to an email it only includes the recipient's email address in the reply on a random basis. More often than not, I have to add them in each time. If it did it all the time I would think it was a setting but random being random, I can't pin this one down. I have reinstalled without any change. Any ideas?

• No internet access on Windows 7 - part 2

  - by Vnuk

  This is a continuation of my previous question. The problems started when I turned on my wireless connection for the first time. Since then, every time I boot my Windows 7, my LAN connection does not have internet access. In my previous question, I got a key answer (route delete). Now my procedure to get LAN internet connectivity (local network works fine) when I boot looks like this: Power on WLAN Disconnect LAN cable Power off WLAN Execute route delete 0.0.0.0 if 11 Connect LAN cable Now my LAN connection has internet access. Another behavior that I can't explain - while my LAN connection has no internet access, Network and Sharing center refers to it as Unknown network, with a public icon. When I go through the fore mentioned procedure, it is referred to with my home WLAN network name, with status connected, and the Unknown network disappears.

• Network Services disabled (not starting) on Windows XP

  - by Rickesh John

  I am currently running Windows XP Service Pack 3 on my system. But today, when I failed to connect to the internet, via a LAN cable, I realized that almost all of the vital network services had stopped functioning. Any attempts to start it through services.msc gives me the following message: Could not start the DNS Client Service on Local Computer Error 1068: The dependency service group failed to start All my software or services that are related to networking have stopped functioning, for example, Windows Firewall is turned off permanently, so is my Avast Anti-Virus' service of Real Time Shields and Web Shield. When I insert the LAN wire into my laptop, it registers itself, but this is what I get when I do a ping localhost C:>ping localhost Unable to contact IP driver, error code 2 Moveover, with ipconfig I get this : Windows IP Configuration An internal error occurred: The request is not supported. Please contact Microsoft Product Support Services for further help. Additional Information: Unable to query host name On some further poking around, I saw that none of the "NETWORK SERVICE" process in task manager, except svchost.exe were running. Also, when I first opened the task manager, I saw some 20 processes running with username column empty for most of them. With some search in Google, I found out that these services were important, DHCP DNS Net logon Network connection Network location Awareness TCP/IP Net BIOS Helper none of them, except Network Connections are working, they do not start. The event viewer of my system shows a bunch of 7000 and 7001 event errors. I have tried re installing the network driver, booting in safe mode with networking and tried to enable those services mentioned above. I had disabled System Restore some time back, so I have no restore points for my system. I tried a lot of things from Google searches but none of them worked. Also, with such a long list of issue, I am a little confused as to what should I search on the internet. :( One more thing I would like to mention, previous morning, my anti-virus Avast detected a RootKit buried deep in my system folders. It was removed, but maybe this was a problem caused by the root kit. I did run a boot-time scan but no viruses were found. Please please please advice. Is formatting and re-installation of Windows my only option?

• Updating to Exchange 2013 - any way to do it now?

  - by TomTom

  Exchange 2013 is out, available for some epople already. Got if from the VLC Center, now trying to get an upgrade path that works for some customers. Problem: There is no upgrade. It is "install on new Server, move mailboxes. This means coexistence with Exchagne 2010 for the time to move the Mailbox. Sadly the only compatible Exchange is Exchange 2010 Sp3 - which is not going to be bout for quite some time. Any way to still do an update? Backup, restore to new Server? Any beta of the SP that is good enough to ONLY move the mailboxes? I do not care about the rest - this really is "install Exchange 2013, move mailboxes, UNINSTALL 2010". I am quite - ah - unhappy that at the end the only one who will be able to intall 2013 are new companies right now.

• Check the disk for problems on Debian Lenny

  - by Equ

  Hi guys! I just bought a VPS hosting with Debian Lenny (I'm new to all this world). I've managed to install and setup everthing I need pretty well. My testing website works fast as expected most of the time, but sometimes it is really slow (response time is about 5-10 seconds). I checked everything and seems that there are may be some disk issues. How can I check the disk for problems/performance? What else could possible cause such a behaviour? Thank you!

• check_ssh executed from Nagios server returns "Server answer: ", nothing else

  - by phs

  Commmand works on the host I need to monitor (its IP is denoted as $HOSTADDRESS$ here): [root@host ~]# /usr/local/nagios/libexec/check_ssh localhost SSH OK - OpenSSH_4.3 (protocol 2.0) However, on the Nagios server, it does not: root@server:~# /usr/lib/nagios/plugins/check_ssh -H $HOSTADDRESS$ Server answer: I can see that the port is open: root@server:~# /usr/lib/nagios/plugins/check_tcp -H $HOSTADDRESS$ -p 22 TCP OK - 0.123 second response time on port 22|time=0.123277s;;;0.000000;10.000000 And I can verify with telnet: root@server:/etc/nagios3/conf.d# telnet $HOSTADDRESS$ 22 Trying $HOSTADDRESS$... Connected to $HOSTADDRESS$. Escape character is '^]'. After searching the web for two hours and trying different suggestions I am out of ideas. I have several other hosts with similar setup, and they don't have this problem. I have compared the configs and they look the same (I think). I am clearly missing something here.

• Multiple users writing to one Samba mount point in OSX

  - by Sam

  I have an OSX box containing a script which writes a unique file to a Samba share. The first part of the script mounts the share. On the machine are 2 users- UserA and UserB. Each requires to run this script at any given time however only the user who mounted the share is able to write to it. I really need both users to have rwx access. Here is what I have tried: Mounting then chmod'ing the mountpoint (no effect- overruled by Samba server?) chmod'ing the mountpoint then mounting (same as above) sudo mount_smbfs Both users have admin privileges. Ideally a solution would be executable by one of the users (contained in the script) and not rely on mounting at machine boot time. Any ideas appreciated, thanks!

• Is a PCIE X1 card for USB 3.0 worth it?

  - by lelouch

  I have a portable HDD on USB 3.0, and soon I'll have a 32gb flash drive on USB 3.0 as well. My motherboard is pretty old - and the next time I'll upgrade it is when I get a new CPU/mobo/ram. Slots on my mobo: PCIE X16 - For my GTX 260 2xPCI PCIE X1 I'm considering purchasing a PCI express X1 card like this - http://www.ebay.com.au/itm/PC-Laptop-2-USB3-0-Ports-PCI-E-PCI-Express-X1-Card-New-/280772000446?pt=AU_Networking&hash=item415f50babe Now the question: What are realistic (read/write) speeds I'll get in this setup, assuming I have 1 USB 3 device connected at a time, and the bottleneck is the PCIE?

• if a usb pen drive has 64349 cylinders, is it damaged?

  - by Andrew S

  I have a 4Gb USB pen drive that I'm trying to format with FAT32. When I run fdisk, it gives me this message: The number of cylinders for this disk is set to 64349. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) I've tried deleting the partition table, creating new partitions, etc, but they never work. Sometimes I can write to the drive the first time I use it after formatting it, but then it becomes read-only in both Windows and Linux. I've tried this on multiple computers. Am I doing something wrong, or is the drive reporting an incorrect number of cylinders? Is the drive itself likely to be corrupted, and is there anyway to fix this under Windows Vista or Linux? Thanks

• ntpdate works, but ntpd can't synchronize

  - by dafydd

  This is in RHEL 5.5. First, ntpdate to the remote host works: $ ntpdate XXX.YYY.4.21 24 Oct 16:01:17 ntpdate[5276]: adjust time server XXX.YYY.4.21 offset 0.027291 sec Second, here are the server lines in my /etc/ntp.conf. All restrict lines have been commented out for troubleshooting. server 127.127.1.0 server XXX.YYY.4.21 I execute service ntpd start and check with ntpq: $ ntpq ntpq> peer remote refid st t when poll reach delay offset jitter ============================================================================== *LOCAL(0) .LOCL. 5 l 36 64 377 0.000 0.000 0.001 timeserver.doma .LOCL. 1 u 39 128 377 0.489 51.261 58.975 ntpq> opeer remote local st t when poll reach delay offset disp ============================================================================== *LOCAL(0) 127.0.0.1 5 l 40 64 377 0.000 0.000 0.001 timeserver.doma XXX.YYY.22.169 1 u 43 128 377 0.489 51.261 58.975 XXX.YYY.22.169 is the address of the host I'm working on. A reverse lookup on the IP address in my ntp.conf file validates that the ntpq output is correctly naming the remote server. However, as you can see, it appears to just roll over to my .LOCL. time server. Also, ntptrace just returns the local time server, and ntptrace XXX.YYY.4.21 times out. $ ntptrace localhost.localdomain: stratum 6, offset 0.000000, synch distance 0.948181 $ ntptrace XXX.YYY.4.21 XXX.YYY.4.21: timed out, nothing received ***Request timed out This looks like my ntp daemon is just querying itself. I am thinking about the possibility that the router-I-don't-control between my test network timeserver and the corporate network timeserver is blocking on source port. (I think ntpdate sends on port 123, which gets it around that filter and is why I can't use it while ntpd is running.) I have email in to the network folks to check that. Finally, telnet XXX.YYY.4.21 123 never times out or completes a connection. The questions: What am I missing, here? What else can I check to try to figure out where this connection is failing? Would strace ntptrace XXX.YYY.4.21 show me the source port ntptrace is sending from? I can deconstruct most strace calls, but I can't figure out the location of that datum. If I can't directly examine the gateway router between my test network and the timeserver, how might I build evidence that it's responsible for these disconnections? Alternately, how might I rule it out?

• Battery won't charge and BSOD: DRIVER_POWER_STATE_FAILURE

  - by JamesGecko

  I have a Dell Vostro 1510 running Windows 7. Today when I pulled my machine out of it's bag and plugged it in, the little battery light on the side blinked constantly instead of staying solid, and Windows showed a message that the battery was not charging. The battery is 3.5 years old, but it can still hold the machine in standby overnight, so I don't know why it won't charge anymore. After I have had the machine on for a while (20 minutes the first time, 40 minutes the second time), it shows a blue screen of death with the message DRIVER_POWER_STATE_FAILURE and reboots. I can deal with the battery being dead, but not with blue screens of death. Does anyone know how to fix it? Edit: Potentially relevant, this started happening after an OS update was automatically installed on Friday and Windows started nagging to reboot. The first BSOD was before the reboot; the update made a lot of registry changes when the machine came up, and the second BSOD was 40 minutes later.

• Registry (possibly) error in Windows 7 : I can not resize columns in any program except explorer

  - by Klugeman

  I experimented with Winbuilder and after some time I noticed that I cannot resize columns in uTorrent, move bookmarks and bookmark folders in Chrome, then cannot resize columns in Comodo Programs Manager - everywhere !!! Fro example , in uTorrent, columns just froze where I left them last time. But Windows Explorer is functioning properly. Where should I search for this problem ?? I think this is something wrong with registry, but regular registry cleaners do not helps. And I cannot even resize a columns in regedit - this is a real hell !

• Is there a program that will show a tree of the differences in two file trees?

  - by Huckle

  In windows I manually back up from time to time by formatting my external drive and copying the contents of my data partition over. Inevitably there is a difference in the number and size of the files copied because of system files, etc. Is there a program that would diff two directories recursively and compile the differences into a nice GUI tree that I could peruse (preferably filter) to ensure that everything I want made it over to the drive? It should only show files that are not in both directories. (Also, please ignore the inadequacy of my backup solution)

• Windows 7: Screen will power off, or blank and lock, but not both.

  - by Heptite

  For some reason, my Windows 7 (Ultimate, 64bit) laptop will not power off the display and keep it off if I have the screen saver and/or the timed auto-lock enabled. Either the display blanks (and locks) but never powers off, or it powers off for less then a minute, then the back light visibly powers back on and stays on, even though the screen remains blanked until I touch a key or the trackpad. I've tried varying the screen power down time to greater than, less than, and exactly equal to the blank screen/lock time, with no success. Turning the screen saver and the timed auto-lock off does allow the timed display power down in the power settings to work properly. (Note that I am not talking about system sleep or hibernate. I'm talking about when the machine remains running, but only the display should power down.)

• Fix two-finger Trackpad Scrolling on a Macbook running Bootcamp

  - by roryok

  This is an issue that's annoyed me for some time. About a year ago, the two-finger scrolling in Windows 7 on my Macbook Pro stopped working. I discovered that a fix for this is to open Bootcamp from the control panel, go to the Trackpad tab, tick and untick "Tap to click" and click ok. This has to be done every time the machine is woken from sleep or rebooted. I'm now using Windows 8 and encountering the same issue. I've tried several different driver revisions, and none have helped. I'm sick of going through the motions. Has anyone got a solution for this?

• What should a hosting company do to prepare for IPv6?

  - by Josh

  At the time of writing The IPv4 Depletion Site estimates there are 300 days remaining before all IPv4 addresses have been allocated. I've been following the depletion of IPv4 addresses for some time and realize the "crisis" has been going on for many years and IPv4 addresses have lasted longer than expected, however... As the systems administrator for a small SaaS / website hosting company, what steps should I be taking to prepare for IPv6? We run a handful of CentOS and Ubuntu Linux systems on managed hardware in a remote datacenter. All our servers have IPv6 addresses but they appear to be link local addresses. Our primary business function is website hosting on a proprietary website CMS system. One of my concerns is SSL certificates; at the moment every customer with an SSL certificate gets a dedicated IPv4 IP address. What else should I be concerned about / what action should I take to be prepared for IPv4 depletion?

• How do I stop ssh-agent from forgetting my password after I login to the screen session from SSH?

  - by Shwouchk

  I have a screen session open in an lxterminal window. If I SSH somewhere, the first time it happens, an ssh-agent window opens and asks me for my private key passphrase, and after that ssh goes right on. If I log in from outside to this machine and attach to the screen session however, ssh-agent now asks me every time I connect for my passphrase, in the terminal. Is there a way to avoid this and to let it continue using the X agent, or at least to have the non-X agent remember the passphrase?

• Can I remove a RAR file's (known) password without recompressing the archive?

  - by Abluescarab

  Long title. Anyway, I haven't been able to find an answer to this question. I know the password to the RAR file, I locked it myself, but now all I want to do is remove the password because it's too much of a pain in the butt to type it in every time. Is there a way to do this in WinRAR or an equivalent program? The only thing I knew to do was to extract it, then create a new RAR without the password. It's not a life-or-death issue, but it would be nice to know. Thanks for your time! EDIT: I just saw a bunch of related questions that appear to ask the same thing. The only solution I saw was using a DOS command to yadda yadda yadda. Here it is: How to remove password protection from compressed files Is there an easier way? Thanks again!

• Distribute Nagios to reduce false alarms

  - by GDR

  I'm currently running a single Nagios instance. From time to time, I'm getting false alarms about timeouts - for example, it says that HTTP is down on some server, but when I open it in my browser several seconds later, it loads fast, and in general there is no trace of an error. What can I do to reduce such false alarms? I'm guessing that it's because of transient network issues on my monitoring server. I guess that setting up another monitoring server on a different network would greatly help, but how do I plug it into Nagios? Is it at all possible with Nagios or do I have to switch to another monitoring system? I like my configs and, if possible, I'd like to stay with Nagios or something compatible (Icinga?)

• How can I measure TCP timeout limit on NAT firewall for setting keepalive interval?

  - by jmanning2k

  A new (NAT) firewall appliance was recently installed at $WORK. Since then, I'm getting many network timeouts and interruptions, especially for operations which would require the server to think for a bit without a response (svn update, rsync, etc.). Inbound SSH sessions over VPN also timeout frequently. That clearly suggests I need to adjust the TCP (and ssh) keepalive time on the servers in question in order to reduce these errors. But what is the appropriate value I should use? Assuming I have machines on both sides of the firewall between which I can make a connection, is there a way to measure what the time limit on TCP connections might be for this firewall? In theory, I would send a packet with gradually increasing intervals until the connection is lost. Any tools that might help (free or open source would be best, but I'm open to other suggestions)? The appliance is not under my control, so I can't just get the value, though I am attempting to ask what it currently is and if I can get it increased.

• Will this RAM work well in an iMac?

  - by sala_7

  I want to increase the RAM of my 2.4GHz Intel Core 2 Duo 24" iMac. I currently have 1GB of RAM DDR2 SDRAM 667 MHz. I really want to upgrade, but know nothing about RAM or hardware in general... These are the cards I found: http://www.crucial.com/eu/store/mpartspecs.aspx?mtbpoid=D4B6F603A5CA7304 Are these of quality or should I look at something else? Finally, I have 800MHz of Bus speed, couldn't I get faster RAM? Thanks for taking the time to read, and hoping you take the time to answer.

• Auto logon to internet provider

  - by user31673

  We use wireless internet access. The wireless is secured and to get an IP address, you provide the right key. That is setup just fine. However, on top of that, the first time we access the internet, a browser page appears and we have to enter a password. then we have access to the internet for a period of time. How can the password step be automated? I also have a web-based printer that doesn't work (except via USB connection) because it can't get out to the web. I can't change the router settings. Is there anything I can do to get the printer working and automatic the access?

• Failing SSHFS connection drags down the system

  - by skerit

  From time to time my sshfs mount fails. All programs using the mount freeze when it happens. I can't even ls anything or use nautilus. Is there a way to find out what's the cause and how to handle it? I've noticed regular SSH sessions to the server get their fair share of Write failed: broken pipe disconnects, too. If I wait long enough (and I'm talking about 20-ish minutes, here) it will auto reconnect and things start working again.
