• How can I run Ghost from a bootable USB key drive?

  - by Joe Philllips

  I have a laptop that does not have a cd-rom or floppy drive. It is able to boot from USB though. I have a disk image (ghost) of the disk that I need to restore back onto the laptop. I can't find a way to actually run the Ghost utility from a USB key though. I believe the ghost.exe should run from within DOS just fine but I can't seem to create a bootable USB key with DOS on it that allows me to run an EXE. Edit: I managed to find a Ghost utility that I could load from a bootable USB drive. Unfortunately, when I plug in my NTFS external drive (USB), it is not detected.

• Best way to block a country by IP address?

  - by George Edison

  I have a website that needs to block a particular country based on IP address. I am more than aware that IP-based blocking is not a foolproof method for blocking visitors, but it is a necessary step in the right direction. Since I'm using PHP, what I would do is use a GeoIP database like geoplugin.net. However, I'm curious to know if there's a better way of doing this. The website is on a shared webserver (I don't have root access) and it is running Apache on centOS. I guess my question is "can an .htaccess file be configured to block by IP using an external source to lookup IP addresses."

• How to query a DHCP server to get the local DNS servers

  - by Dan Berlyoung

  I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a) reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b) calling their tech support (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?

• View unknown content-types in Firefox?

  - by dirtside

  A certain URL on my server returns Content-Type: application/json. The filename ends with .phtml, so whenever I go to it, Firefox 3.5 asks me if I want to save it or open it with another program. But the answer is neither; I want to view it in Firefox as if it was text/plain. Suggestions? The Applications tab of the Preferences window doesn't give this as an option for the "PHTML" type which now is listed in there (ever since I tried to open it with no external program).

• Where do Outlook folders go when moved?

  - by balexandre

  I have an account with external user mailboxes opened and accidentally I have moved a folder and now I can't find it anywhere. Action: I clicked on a folder and dragged it into another one. Result: Can't find the moved folder anywhere The above picture is the folders I currently have from my Outlook 2010 (via Exchange 2010), under an AD Network. Where can I (me, having admin rights over the network) retrieve that missing folder again? Attempts: The original and the one folder I need was accidentally moved, but I have created a poi folder and tried the same way, and I got the same result... the folder went missing. I also tried to reboot the client machine and access the same mailbox from OWA ... no luck on both attempts :( Any ideas on how I can retrieve the missing folder and its emails again?

• How to get rid of NAT in a LAN?

  - by Alberto

  Currently the LAN I manage is organized as follows: internal network (192.168.1.0) which uses a Linux server as a gateway (internal address on interface br0 192.168.1.1, external address on interface br1 10.0.0.2) through NAT; then the 10.0.0.0 network has another gateway (10.0.0.1) which through another NAT connects the whole thing to the internet. What I would like to achieve is to configure the Linux server so that the first layer of NAT is no more necessary, so that for example a computer in the 10.0.0.0 network can ping every computer in the 192.168.1.0 network. I deleted this iptables rule: iptables -t nat -A POSTROUTING -o br1 -j SNAT --to-source 10.0.0.2, but of course now computers on 192.168.1.0 cannot reach the internet; ip forwarding is of course enabled. What's missing here? Thanks

• Help desk software - specific feature needed

  - by LunchMoney

  I am having a hard time finding help desk software that allows for drop down hyperlink selection during ticket creation. The situation is that we do external support for client systems and connect via remotely anywhere or logmein. Right now we use a poorly modified php based system that has a customer drop down menu and then a site drop down list that is then parsed by a bit of java script which opens a url. What I am looking for is the ability to store customer site URL information in the database and during the creation of a ticket be able to select the customer name and then select the site there by placing the corresponding site URL in the ticket. The support tech will then be able to click on this link to access the customer's site. Has anyone used or seen help desk software with this feature?

• AWStats log format for tomcat access logs which has X-Forwarded-For

  - by Nix

  What should be the AWStats log format for below tomcat access logs ? I tried these formats but the external IP addresses are not coming into AWStats reports. LogFormat="%host %other %logname %time1 %methodurl %code %bytesd %refererquot %uaquot %referer %other %other" LogFormat="%other %other %logname %time1 %methodurl %code %bytesd %refererquot %uaquot %host_proxy" tomcat valve settings: pattern="%h %l %{USER_ID}s %t &quot;%r&quot; %s %b &quot;%{Referer}i&quot; &quot;%{User-Agent}i&quot; &quot;X-Forwarded-For=%{X-Forwarded-For}i&quot; &quot;JSESSIONID=%{JSESSIONID}c&quot; %D" Log entry: 127.0.0.1 - - [04/Nov/2013:13:39:55 +0000] "GET / HTTP/1.1" 200 12345 "https://www.google.com/url?some_url" "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36" "X-Forwarded-For=real_ip, proxy_server_internal_ip" "JSESSIONID=-" 12345

• Windows Server vs Sharing

  - by Mark Lawrence

  Not sure if this is the right place for this question. I have a friend that owns a small business running 3 local machines, that are connected to the internet, and a server that each local machine connects to. He has recently bought a newer server, and by server I mean a Windows Vista box. He wants to use this purely to store data that the 3 local machines can access, kind of like a glorified external hard drive. Im suggesting to fore-go the server option and simply setup sharing on the 'server' box. Interested in hearing any suggestions as to whether the server idea is preferable?

• How can I register a custom protocol with xdg?

  - by julien

  I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.

• Routing application traffic through specific interface

  - by UnicornsAndRainbows

  Hello All! First question here, so please go easy: I have a debian linux 5.0 server with two public interfaces. I would like to route outbound traffic from one instance of an application via one interface and the second instance through the second interface. There are some challenges: both instances of the application use the same protocol both instances of the application can access the entire internet (can't route based on dest network) I can't change the code of the application I don't think a typical approach to load balancing all traffic is going to work well, because there are relatively few destination servers being accessed in the outbound traffic, and all traffic would really need to be distributed pretty evenly across these relatively few servers. I could probably run two virtualized servers on the box and bind each of them to a different external ip, but I'm looking for a simpler solution, maybe using iproute or iptables? Any ideas for me? Thanks in advance - and I'm happy to answer any questions.

• How to route all traffic over site to site VPN tunnel?

  - by Hutch

  I have a site to site VPN configured between our main site (Site A) and a remote site (Site B). Site A is 10.60.0.0/16 Site B is 192.168.99.0/24 The firewall in Site B is a Juniper SSG running ScreenOS 6.3 and I'm using a route based VPN. The tunnel works perfectly in that from Site A you can reach 192.168.99.0 via the tunnel, and from Site B you can reach 10.60.0.0 via the tunnel. However, we want it so that if you're in Site B and want the Internet it goes via the firewall at Site A, and right now on the Juniper 0.0.0.0 has the ISP router as next hop. My understanding is that on the Juniper, I can set a route for the /32 public IP at our main site that the VPN tunnel connects to to the ISP router via ethernet0/0 (the SSG's external interface), and then modify the 0.0.0.0 route to use our main site firewall via tunnel.1 (the VPN tunnel). Not sure I've explained that so well but is my understanding correct? Thanks

• IIS FTP service - download timeouts and restarts getting the data twice

  - by accel229

  We have an IIS FTP site on a Windows Server 2003 x64 machine. Application Layer Gateway service is disabled (so http://support.microsoft.com/kb/931130 does not apply). Windows Firewall service is disabled as well. Connection timeout for the FTP site (there is only one) is set to 1,200 seconds = 20 minutes. An external client can connect to the site, list directory contents and download small files. When a client attempts to download a large file (eg, if the download continues for 3 minutes, which is still under 20 minutes, but relatively long), the server sends all data, then the connection times out, the client issues REST / RETR commands attempting to restart the download since after the last byte (which I believe should succeed and receive exactly 0 bytes), and the server behaves as if the client tried to restart after byte 0, that is, it sends the entire file all over. Any ideas on how to fix this?

• Force users to access SSL site using specific host header

  - by mwillmott

  Hi, So i am running IIS7 with one SSL site on it. I have a few different domains and subdomains that all point to my external IP. When using http they all direct to their respective sites using host headers. Whenever someone uses https on any of the domains they all point to my SSL site. I only want people who type in https://sub.domain.com (for example) to end up at my secure site and for anything else to just not go there, it can throw an error or direct to the http version, it doesn't matter. Is there a way of getting IIS7 to check the host header and throw an error if it doesn't match my specific subdomain? Thanks, Michael

• Volume Shadow Copy based backup that works with TrueCrypt?

  - by jasonh

  I have enabled whole-drive encryption on my external drive to comply with my company's requirements about data security. I want to be able to make a backup of files on the drive, even while they're in use. Is there any program out there that uses Volume Shadow Copy for backup and also works with a TrueCrypt encrypted drive? I have tried Windows Backup and Macrium Reflect and both act like the drive isn't connected, even though TrueCrypt has mounted it. It would be really nice if there was something that was free, but in order for that to work, it also has to work for commercial purposes since this is my company laptop I'm trying to backup.

• Lenovo G530 laptop screen flicker

  - by Kevin

  I have a Lenovo G530 laptop that has an issue with screen flicker that is getting worse. The computer screen will start going thru a crazy screen flicker then will stop and start again. I have already checked cable connection to lcd on motherboard and reseated connection as someone suggested in another posting I found online that resolved issue. I am starting to think it might be a bad inverter or screen because I have hooked up laptop to external monitor and it is running fine with no flickering happening when the flickering is occurring on laptop. I am attaching a link to a small video I shot of the issue as it is occurring on laptop screen. Does anyone have any further suggestions? Bad inverter or screen? Screen flicker vid

• Do two portforward rules translate to "and"?

  - by blsub6

  I just set up an Exchange server to replace my DeskNow mail server. I want to start testing my internet mail exchange of my Exchange server. I can only set the MX records on my DNS up to my one external IP address so I was thinking that I could set up a firewall rule on my internet-facing firewall that port forwarded the smtp packets to two different servers. My question is: If I do that, will that mean that the smtp packets will be forwarded to just the first internal IP on the list? Or does it mean that the packet will be cloned and sent to both IPs?

• Hard drive caught malware and all folders are in shortcuts

  - by Ammar

  I have an external hard drive from Seagate. I think it accidently caught a malware/virus, since all the files in there became shortcut folders. I have very important folders and now I cannot access them at all. I did not have an antivirus program; I just formatted the PC and forgot to install one. Just recently, I installed Avira and it caught the malware, but since I removed the malware via Avira, I can't access anything now. Please help me on what I need to do. I am really lost.

• Disk Utility Restore causes "Could not validate resource - Invalid Argument"

  - by Yahoo

  I have a problem with Disk Utility on Mac OS X 10.6. I have an image of Windows that I would like to use as a bootable volume on a pen drive or external hard drive. The thing is: When I try to restore the volume from the image I get an error: "Restore Failure: Could not validate resource - Invalid Argument" I read some information about that error on the Internet. I converted the image into .iso (Mac OS Extended/ISO (Joliet) Hybrid Image) format and then got this error: "Restore Failure: Could not find any scan information. The source image needs to be imagescanned before it can be restored." When I try to scan the image for Restore, I get the first message. I really read a lot of information about this topic on the Internet, but I haven't found the solution. I tried both ISO and DMG formats; I don't know which is best.

• MySQL won't stop doing stuff

  - by Felix

  Sorry for the title of the question, here's my problem: I've been trying to set up some scripts that import a lot of stuff hourly from an external source. They seemed to work fine, so I set up a cronjob to run them every hour. One day later I find six or seven instances of that script just hogging the MySQL server, making it unresponsive. I killed their processes, but MySQL was still not responding. I had to kill MySQL, reboot and then MySQL started working again (who knows on what) and being unresponsive (yes, I did remove the scripts from the cronjobs). I SHOW PROCESSLISTed and killed every process I could find. Still nothing, MySQL is hogging the HDD and is at the top of top and making the server load go up in the sky. I don't know what to do, if I kill and start it again it will probably do the same thing. What should I do?

• Areca 1880ix RAID hangs

  - by Dave

  Areca RAID controller ARC-1880ix-12 (firmware 1.50) hangs when on high load. My setup is: Chenbro 3U chassis Intel S5500BC mainboard Xeon 5603 CPU 16GB of RAM 12 Seagate SAS drives ST32000645SS (2 of them as hot spare, 10 as RAID10) Mellanox Infiniband HBA card This server is working as external infiniband storage for Xen VMs. When load is quite big Areca's firmware hangs - it becomes unreachable even from Areca's ethernet adapter. After resetting the server power it returns to normal operation. While Areca is hanged I can confirm that it is powered (ethernet link is active) and Infiniband HBA works Ok. Thanks in advance for any idea or suggestion where the problem might be!

• Simulating network latency for localhost connection on Windows 7

  - by nitro2k01

  I need to simulate network latency to a program running on the local computer, connecting to a local service. Thus far I have tried dummynet (a windows build of ipfw) which I got working after some trial and error. While it generally works, I can't seem to get it to filter localhost traffic. Even after adding a rule from any to any which affects external traffic, this makes no difference for local connections. I would appreciate if anyone knows how to simulate local latency using dummynet or a different tool. The tool should be able to simulate latency generically in IP packets, (TCP and UDP) and not be protocol specific.

• Windows CMD, show the current folder name at prompt dynamically like Bash

• Time machine link error

  - by robinjam

  When attempting to perform a Time Machine backup, the backup appears to proceed as normal, until it finishes copying files at which point it complains that an "error occurred while linking files for" one of my external hard disks. During the previous backup that particular disk was in fact empty, and therefore I can't understand why Time Machine is attempting to link back to it. But alas. I've verified all my disks using Disk Utility and they all appear to be fine. Does anybody know what causes this error, and how I might go about fixing it? Failing that is there a way to force Time Machine to create a brand new backup rather than an incremental one? Thanks in advance!

• RAID--0 " TWO " DRIVES SSD ONLY Should I use on-board / Software RAID OR a RAID Card / Control

  I am looking at going with a TWO Drive Only SSD RAID-0 Configuration And was wondering if I would get better performance / Speed from the Use of a RAID Controller / Card Verses just using the Software RAID on my Mother Board. I have herd conflicting reports , Again I only Plan on Running " 2 " SSD Drives in RAID-0 Config I have No- problem spending the extra money for a good controller but only if I am going to benifit performance wise , Otherwise if there is no notable Gain I will just use the Software RAID that my HP-180-T came with Intel- 3.33 GHZ , 6-Core , 12-GB of DDR-3. I have a huge External drive for All Storage and am not concerned about Data loss just looking for pure speed. And if a Controller will benifit my performance Wht type of card would one suggest?
