• How to connect via SSH to a linux mint system that is connected via OpenVPN

  - by Hilyin

  Is there a way to make SSH port not get sent through VPN so when my computer is connected to a VPN, it can still be remoted in via SSH from its non-VPN IP? I am using Mint Linux 13. Thank you for your help! This is the instructions I followed to setup the VPN: Open Terminal Type: sudo apt-get install network-manager-openvpn Press Y to continue. Type: sudo restart network-manager Download BTGuard certificate (CA) by typing: sudo wget -O /etc/openvpn/btguard.ca.crt http://btguard.com/btguard.ca.crt Click on the Network Manager icon, expand VPN Connections, and choose Configure VPN A Network Connections window will appear with the VPN tab open. Click Add. 8. A Choose A VPN Connection Type window will open. Select OpenVPN in the drop-down menu and click Create.. . In the Editing VPN connection window, enter the following: Connection name: BTGuard VPN Gateway: vpn.btguard.com Optional: Manually select your server location by using ca.vpn.btguard.com for Canada or eu.vpn.btguard.com for Germany. Type: select Password User name: username Password: password CA Certificate: browse and select this file: /etc/openvpn/btguard.ca.crt Click Advanced... near the bottom of the window. Under the General tab, check the box next to Use a TCP connection Click OK, then click Apply. Setup complete! How To Connect Click on the Network Manager icon in the panel bar. Click on VPN Connections Select BTGuard VPN The Network Manager icon will begin spinning. You may be prompted to enter a password. If so, this is your system account keychain password, NOT your BTGuard password. Once connected, the Network Manager icon will have a lock next to it indicating you are browsing securely with BTGuard.

• How to prevent eMule from jamming up the router?

  - by the searcher

  Usually, when eMule is started, after some time, I find that the router is jammed, so the internet connection on that computer stopped working, or it seemed to be waiting for some port to be freed up before it can connect to a website. This sometimes affect even other PCs or Macs using the same router. Is there a way to prevent eMule from hogging too much resource or ports? I see that there is under Options -> Connection "Max Sources/File" and a "Connection Limits - Maximum Connections". Right now I set them to really low numbers: the first to 120 and the second to 200, but what are good numbers to fill in there so that it can work well without jamming up the router or use up the network resource of the PC or Mac? Or could it be that the number of files that are "Waiting" is too high, and used up too much resource? (If so, can emule automatically limit the number to 10 or 20 to prevent using too much resource?) (This happened before on Linksys router, Netgear router, and the AT&T U-verse router.)

• Certificate revocation check fails for non-domain guest in spite of accessible CRL

  - by 0xFE

  When we try to use certificates on computers that are not part of the domain, Windows complains that The revocation function was unable to check revocation because the revocation server was offline. However, if I manually open the certificate and check the CRL Distribution Point property, I see an ldap:/// URL and an http:// URL that points to externally-accessible IIS site that hosts the CRLs. Of course, the non-domain-joined client cannot access the ldap:/// URL, but it can download the CRL from the http:// link (at least in a browser). I enabled CAPI logging and I see the event that corresponds to this failed revocation check. The RevocationInfo section is: RevocationInfo [ freshnessTime] PT11H27M4S RevocationResult The revocation function was unable to check revocation because the revocation server was offline. [ value] 80092013 CertificateRevocationList [ location] UrlCache [ url] http://the correct URL [fileRef] 6E463C2583E17C63EF9EAC4EFBF2AEAFA04794EB.crl [issuerName] the name of the CA Furthermore, I can see the HTTP request to the correct URL and the server's response (HTTP 304 Not Modified) with Microsoft Network Monitor. I ran certutil -verify -urlfetch, and it seems to show the same thing: the computer recognizes both URLs, tries both, and even though the http:// link succeeds, returns the same error. Is there a way to have non-domain-joined clients skip the ldap:/// link and only check the http:// one? Edit: The ldap:/// URL is ldap:///CN=<name of CA>,CN=<name of server that is running the CA>,CN=CDP,CN=Public Key Services,CN=Services,CN=Configuration,DC=<domain name>?certificateRevocationList?base?objectClass=cRLDistributionPoint The non-domain-joined clients may be on the domain network or on an external network. The http:// CDP is accessible from the public internet.

• How do I change Firefox's user agent via about:config?

  - by wahle509

  My work has blocked Internet access with Firefox. I know how to change the value of “general.useragent.extra.firefox” through about:config, but when I try to change it to IE, I still can’t access any website. I have Firefox 3.5.6 and Internet Explorer 7 installed on my desktop. Now, would I have to use the user agent that Internet Explorer 7 is currently using on my computer or can I use any Internet Explorer user agent? The user agent that Internet Explorer 7 is using right now is: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022). Do I just copy that and use it as the user agent in Firefox? How can I make this work?

• Converting PDF eBooks into a Kindle format

  - by Ender

  Over the past couple of years I've amassed quite a collection of guides, tutorials and ebooks in PDF format. A lot of these are quite useful for work, especially PDF documentation, and rather than have to be at a computer every time I want to read how to do something in Sitecore or to read through a software testing ebook I'd like to do it on my brand-spanking-new Kindle. However, even though there is now a native PDF reader on the Kindle due to the nature of PDF's they are practically unreadable. The text doesn't wrap due to how PDF's are sized and so far after a bunch of Google searches I've yet to find a viable solution to get my PDF's converted into a readable Kindle format. Sometimes these books have code or pictures/tables in them, but most of the time they're text-heavy and to be honest I'd be surprised if there wasn't a free tool to handle the converting of PDF to one of the (seemingly many) Kindle formats. So, can anyone help me out with this? EDIT: I've tried Calibre, and have checked their forums to play with some of the advanced settings, yet the solutions available seem to be extremely poor, especially if the book you're attempting to read contains equations, code, or anything outside of plain text. I've also tried Amazon's conversion service, which wasn't much help with such documents. The best way I have found so far is to build the entire thing over again in ePub or RTF format and convert to MOBI from there. This works for text-heavy books with tables, but anything technical still isn't covered. Can anyone help with this?

• Adding Windows 7 32 bit as dual boot option

  - by djerry

  A relative of mine has bought a new laptop this year on which windows 7 (64 bit) is installed. Aside some standard programs he uses on that laptop, he also has some software for his bike that needs to run. The developers of that program still don't support 64-bit systems and therefor I thought about making it dual boot, so he can still use the power of the 64-bit, and just for the bike program, he can initiate the 32-bit version. My questions now are: What are the risks involved in this operation? What steps need to be taken to make this dual boot succesful? Any other ideas besides dual booting? Thanks in advance. Edit I might have forgotten/misphrased something. The software does run on 64-bit, but it cannot find the bike connected to the computer. So I think it's a matter drivers which aren't compatible with the 64-bit system. That's why I wanted to install the 32-bit windows so the drivers would work.

• Windows 7: Wi-Fi connection drops intermittently - only returns after "Troubleshoot connection" resets the adapter

  - by sleske

  On our laptop (running Windows 7) the Wi-Fi connection drops intermittently. Symptoms: Connectivity is suddenly lost, and the "signal strenght" indicator in the tray shows zero strength and a yellow "star" symbol. What happens then: The problem does not resolve itself by just waiting. If I click on the tray icon, the "Windows network diagnostics" wizard pops up and tells me that there is a networking problem (duh). If I click on the "repair" button (not sure about the wording), the wizard works for a while, then reports that it has reset the network adapter. Then Wi-Fi works again. While the above procedure has worked every time so far, it is very annoying. It takes 10-20s to repair the connection, and in the meantime downloads, video streams etc. may have been aborted. Some more details: The problem occurs without any apparent regularity, but usually a few minutes after powerup (though not every time). It happens frequently enough to be annoying. It is unlikely to be a router problem - another laptop running at the same time usually has no Wi-Fi problems. I am at a loss about what to try to troubleshoot this. Any ideas? Computer: Acer Aspire 7739Z. Wi-Fi card: Atheros AR5B125

• Netgear router is not resolving hostnames

  - by Thomas Clayson

  Not sure what the problem is, but I am used to being able to access other clients on my LAN via their hostname. We got a new router from plusnet (Netgear WNR1000v3) and now this has stopped working. For instance, if I were to run a web server from one computer with the hostname TomPC usually I could go into a browser and type http://TomPC and I would get the web server front page. I can access it by using the LAN ip of the machine. e.g. http://192.168.1.1 works fine. I thought it would be a simple option in the admin panel of the router - possibly I had to turn on DNS/DCHP or something. But I can't see anything, and my searches on the internet seem to turn up ridiculous solutions involving setting up a dedicated DNS server on my LAN. This is just a small home network - really I just want to be able to access my Raspberry PI on the network without having to work out the IP address every time. (I know I could just set a static IP address for it, but using its hostname would be much easier). DCHP is enabled in the LAN settings part, although RIP is disabled (I don't know what the latter is) I don't know if this has anything to do with it? Many thanks!

• Port forwarding with multiple IP's

  - by Jon

  I work at a company which uses a Fortigate 60 router, something I'm not really familiar with. Everything worked fine with it until a week ago when Comcast came in and replaced our modem. It seemed as though the process went smoothly - our connection came back up and our static IP remained the same. However, none of our port forwarding is working. What has me confused is the Comcast modem apparently has two IP addresses. The WAN2 interface for it in the Fortigate router is set to 10.1.10.10. However, all of our port forwarding settings are set to an external IP address of 10.1.10.50. Now this setup used to work fine, so something with the Comcast modem must have changed. How can I find out what? I tried setting a computer to a local IP of 10.1.10.15 so I could open up the web interface for the modem, but I can't even ping 10.1.10.10 when I do that. Any ideas? Thanks!

• How to get data from a borked Windows Home Server

  - by harhoo

  Yesterday we had a power surge, followed by a power outage. This left my WHS borked: powering on just gives to a flashing blue light (the led on the power supply also flashes green) - no fan or boot activity, nothing. I urgently needed some files off there in the short term (and the 500GB of photos, music, personal video etc in the long term) so I took the hard drive out and put it in my computer. The files and folders showed up, but I couldn't access them - clicking on an image gave an invalid image error in Picasa, I couldn't play MP3s etc. I changed the ownership and permissions of the files, still nothing. I booted in with a LiveCD, the same: files appear, but won't open. Is there anything else I can do? I'm now wondering if it was just the power cable that's broken, but if so, why can;t I access my files from the hard drive? If it is the power cable, and I replace that and the hard drive, will I have done any harm messing around with ownership and file permissions?

• Time Machine vs Source Control?

  - by Blub

  Finally got convinced to start using some kind of version control for my code instead of zipping down a copy of the project at the end of each day. Downloaded Tortoise SVN and used it to create a repository localy on my hdd. I've been using it for 2 days now but I have to say that using it is actually more hassle than just copying the project manually in explorer. Sure, you only store incremental changes but with the cheap disks of today I can't really say that's an argument when you only have small projects. I haven't realy found a quick way to browse the older versions of my files eighter. What I want is an infinite undo that is completely transparent while I code, if I save the file I want a backup. I don't want to check out, check in and don't even get me started on moving files. I haven't tried Time Machine for OS X but it looks like it's exactly what I'm looking for. Does such a program exist for windows? Preferably free and with some kind of tagging-system so I can tag a timestamp when the project is working etc. Maybe should add that I mostly work alone on a single computer. Update: Some of you asked why I want backup. Since I work alone it's mostly to allow me to quickly hack up a solution without worrying that something will screw up.

• Does ICS modify windows firewall policies in the registry?

  - by insipid

  I had a host machine I wanted to enable ICS on. First I realized that doing so was not possible until I enabled the Windows Firewall. Once I enabled the firewall and set up ICS, I noticed due to group policy I could no longer disable the firewall. Also, any ports I tried to open seemed to be ignored. Although nothing seemed to be configured when I used the mmc snap-in to view local computer policy, when I checked the registry I noticed several policies set there in HKLM (such as disabling AllowLocalPolicyMerge). I was able to remove the policies from the registry and my open ports worked, but they were eventually re-added without my input. The network I am sharing the internet from is an "unsecured" wireless network with an authentication page, is it possible that this is causing those policies to be set? Did ICS set those policies? When you go to the properties of the ICS enabled adapter and go to the ICS settings it takes you to a tab called services where you can add and remove "services running on your network that internet users can access". Is this related to the windows firewall?

• Can't connect to Server Manager from Windows 7

  - by SAdmin317

  I have a Windows 7 Pro 64bit with SP1 desktop that has RSAT tools installed. I opened Server Manager and can't connect to the server (Server 2008 R2 core). I followed the guide to enable everything on the server, added a registry key to enable read-only on the device manager as well. On the Windows 7 PC I turned on winrm, did the quick config, and added the server IP and name as trusted hosts. I still get an error when connecting. "Connecting to the remote server failed with the following error message: The WinRM client cannot process the requests. If the authentication scheme is different from Kerberos, or if the client computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHosts configuration setting...." I also added the name of the server to the windows 7 /etc/hosts file. Ping the server name translates to the IP of the server. Also opened up the firewall for "Remote Volume Management" Both machines are on the same Workgroup, using the same Administrator account, with the same password. Any help appreciated.

• Ubuntu 10.04->10.10 in failed state - how to recover?

  - by Harvey

  I was running Ubuntu 10.04 and attempted to upgrade to 10.10. I have a really slow connection (DSL 128kbits/sec) and copying the upgrade files took about 26 hours. I of course let it run unattended. When I came back, I notice the following 3 dlgs: (1) "Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg -- configure -a)." (2) "gpk-update-icon Distribution upgrades available maverick 10.10 (stable) [more information] [Do no show this again] [Cancel] [Ok]" (3) "gpk-update-icon Security updates available The following important updates are available for your computer: libwebkit-1.0-2-dbg - Web content engine library for Gtk+ - Debugging symbols libcupsimage2 - Common UNIX Printing System(tm) - Raster image library ..." What is the best response to all of this? I went through something similar in an attempted network upgrade from 8.04 to 10.04 and had to reload the unbootable machine fresh from distribution media (all data was lost). I'd like to avoid that here. I have not yet responded to the dialogs, and want to make sure the system is still bootable and not lose my data this time.

• A little guidance setting up FTP server authentication on Windows Server 2008 R2 standard?

  - by Ropstah

  I have a (clean) server running Windows Server 2008 R2 standard. I would just like to use it for serving a website and a FTP server through IIS. IIS is installed and serves my website propery. I have now added a FTP site but when I try to logon using my user/pass i get the following error: 530 User cannot login From this article (http://support.microsoft.com/kb/200475) I understand that these four causes can be pointed out: The Allow only anonymous connections security setting has been turned on in the Microsoft Management Console (MMC). Not the case The username does not have the Log on locally permission in User Manager. The user is in the Users group, however I'm not able to logon through RDP. I tried configuring this by following this article through GPMC however this only works when I'm logged in as a domain user on a domain controller which I'm not: I'm logged in as administrator The username does not have the Access this computer from the network permission in User Manager. Not sure what this implies...? The Domain Name was not specified together with the username (in the form of DOMAIN\username). Tried adding the server name: server\username, not working... I am an absolute server noob and I'd just like to be able to connect through FTP... Any guidance is highly appreciated!

• Could hybrid SSD + HDD be made with fixed internal partitions?

  - by Aaron

  I was pretty close to getting Seagate's Momentus XT but have been scared off by the many problems reported on forums and feedback sites, especially in Mac Book Pros. So I'm waiting for mk 2 with some extra flash and better reliablilty I'm assuming will come out this year. What would suit me better though is a 32+500 hybrid drive where I have more control over what is on the flash drive and what is on the disk drive. So there are 2 physical partitions within the one 2.5" hard drive enclosure which use different media internally (32GB for core files and 500GB for data and multimedia). The partitions would be locked so they can't be changed. - Or even better, the disk driver just makes them appear as two disks to the OS that share the same bus... Perhaps it's ok if the bios just sees the first drive until the OS is loaded. Is either of it technically possible? Obviously difficult to market outside of the enthusiast market. The SSD memory modules can be pretty small right, so they could even make them a card that plugs into a secondary connection on the enclosure. That would be good for computer builders as well as for upgrading and recoverability. Then future operating systems could recognise these system SSD drives and automatically install the OS + swap files on it. While placing document libraries on the larger data drive. While in the longer term HDD will probably disapear there will always be a trade off between speed, storage size and expense.

• Dialog box tells me there's a missing driver when installing 64-bit version of Windows 7

  - by Eikern

  I'm trying to install Windows 7 64-bit on my computer (ASUS P6T Deluxe V2, one 80GB HDD and two 1 TB HDDs). When I'm supposed to select whether I want to Upgrade or do a Custom install, I get a dialog box telling me: Load Driver A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now. Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step. I've tried to reach this step using a 32-bit installation disc, but that doesn't generate this message at all. Through the command windows (shift-F10) I can reach all of my drives, including my optical drive, without any problems--so what kind of device driver is it the installation wants? I've tried all the obvious drivers on the CD that followed my motherboard, but I can't seem to find the right one. The problem is that I don't know what device I'm supposed to load the drivers for in the first place. Can anyone help me? Edit: It turned out that my downloaded image was corrupted. I borrowed a DVD from a friend of mine, which worked!

• Hard Drive that was used before not detected or accessible in Windows 7

  - by Anders

  Hello SU: My PC crashed for some unknown reason, and I am still working on what caused that. However, I pulled my main (windows) drive from my computer and hooked it up to my roommate's machine and was able to pull the data I needed off of it (i.e. the drive is good). I hook up his drives as they were, I had to turn off his machine and unplug his secondary drive to hook mine up, boot his machine and there is no second drive available in windows explorer. I opened Device Manager to see if for some reason it's drive letter got un-assigned, but there is nothing listed in there except his primary hard drive, his optical drive and one other optical drive which I believe is the virtual drive Daemon Tools made. The drive shows up in the BIOS, however after I restarted his machine again it sits on the "Entering setup....." screen at the load window. The only thing I can think of is that may have messed with stuff is I used this tutorial to create a bootable XP install on a USB drive to install XP on my machine (I am 99% certain that the optical drive in my PC is broken) and maybe it used the other hard drive's letter for the USB drive for some reason, which doesn't make much sense since it was recognized it as a different drive letter before I started the process. It is possible that it used the secondary hard drive's letter for it's work, but once again I am uncertain. Where should I go from here? He his bound to wake up within the next several hours and will probably flip a lid if I cannot get some sort of handle on this. Any and all help is greatly appreciated. PS: Anyone who helps me get this situated has a beer or two on me, as long as you are in the greater metro Detroit area, or don't mind traveling a bit!

• Weird problem with Visual C++ 2010 Express

  - by Robert Vella

  This has happened before on my Vista Premium installation, and now it's happening on my Windows 7 Home Premium installation. Basically everytime I install Visual Studio Express 2010, it works fine for a random amount of time but then suddenly starts to hide from my sight -- that's the best way I can explain it. VS does not crash, and from what I can tell it does not freeze either; It continues to work, I can even "minimize" and "maximize" it; I simply cannot see it nor can I interact with it any meaningful way. Also: After the "crash" there are no logs in: Root\Program Files (x86)\Microsoft Visual Studio 10.0\Microsoft Visual C++ 2010 Express - ENU. Nor any other files created at the time of the crash. There are no traces in the event viewer. The program seems to be functioning perfectly in the process manager. If I reinstall Visual C++, it works normally for a seemingly random period of time before going cookoo again. I am stumped. This has never happened to me before, with any other program. And yet I doubt it really is a problem with Visual C++; More like something general that seems to have picked on it for some reason. Still, after a clean install with a new OS, I'm kinda thinking there's something wrong here. Any help would be appreciated, altough I suspect that the answer to this question will make me feel embarassed. P.S. Not sure if it helps, but I think around the same time I started having problems (On both installations) with windows turning off the display when I leave the computer, and then seemingly crashing when it turns it on again -- in fact when I interact with it it seems to be responding to my commands without actually display anything.

• Why are certain folders in my XP network share really, really slow?

  - by bikefixxer

  I have a workgroup set up with Windows XP. My file "server" is running XP Pro and the clients are running XP home. I've turned simple file sharing off on the server because certain clients need access to certain folders and not to others, and I want to keep it that way. Therefore, I've used the granular sharing/security settings to enable certain clients access to certain folders. I'm using the net use command in a batch file on the clients to add the share when they logon so it's always available via a mapped drive or a shortcut. On some clients "My Documents" points to the mapped drive, but all of the local and application settings stay local. Everything works well except for accessing a certain folder on the network. It contains a lot of random batch files and self-executable programs I use for diagnostics and what not, and nearly every time I open the folder the computer hangs for 15-60 seconds. This happens on every machine, including the server (but not nearly as often as the clients). I've searched high and low and cannot figure it out and it's driving me crazy. Here are all the things I've tried to no avail: Disabled firewall (XP) and anti-virus (ESET NOD32) Deleted any desktop.ini file I can find in the share Disabled "automatically search for network folders and printers" Disabled "remember each folder's view settings" Set HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer NoRecentDocsNetHood = 1 Tried with mapped drives and with UNC shortcuts Ran CHKDSK Removed Read-Only attribute from all folders (well, tried to remove, it always came back on with a half check) Added the server's static IP to the hosts file on the clients I've tried monitoring the server's performance to see if anything makes sense. Occasionally the issue coincides with a spike in pages/sec (memory) but not always. Other than that, everything else seems normal. The anti-virus would seem to be the most likely cause to me considering the batch files and what not, but it still hangs when it is completely disabled. I'm at a loss and if anyone can help me with this I'd greatly appreciate it!

• Win 7 x64 explorer.exe stops responding on copy/paste

  - by Sourabh

  Few months ago I changed my Win7 orb using this software. But it changed only the explorer.exe in C:\Windows. To solve that, I copied explorer.exe from there to C:\Windows\system32 and C:\Windows\SysWOW64 (Probably a bad idea). Things were working fine until a few days ago, it started giving me problems while copying. Sometimes, when I copy/paste, It works fine but sometimes it stays on that dialog box which looks like it is doing pre-copying things like counting number of files/file size etc. But its not. It stays on that screen forever. Now if I try to close it, title changes to cancelling but rest stays the same. If I try to close it too many times, explorer.exe crashes. And its not related to file-size. It may crash for 4Mb file and work fine for 10Gb file but some other time, it'll do the opposite. Is there any way to reset my explorer.exe and Is this because of explorer.exe or something else PS: I forgot to take backup of explorer.exe. PS2: I didn't install any software or downloaded anything that could harm my computer. EDIT I tried System Restore and SFC /scannow but they didn't help.

• openvpn port 53 bypasses allows restrictions ( find similar ports)

  - by user181216

  scenario of wifi : i'm using wifi in hostel which having cyberoam firewall and all the computer which uses that access point. that access point have following configuration default gateway : 192.168.100.1 primary dns server : 192.168.100.1 here, when i try to open a website the cyberoam firewall redirects the page to a login page (with correct login information, we can browse internet else not), and also website access and bandwidth limitations. once i've heard about pd-proxy which finds open port and tunnels through a port ( usually udp 53). using pd-proxy with UDP 53 port, i can browse internet without login, even bandwidth limit is bypassed !!! and another software called openvpn with connecting openvpn server through udp port 53 i can browse internet without even login into the cyberoam. both of softwares uses port 53, specially openvpn with port 53, now i've a VPS server in which i can install openvpn server and connect through the VPS server to browse internet. i know why that is happening because with pinging on some website(eb. google.com) it returns it's ip address that means it allows dns queries without login. but the problem is there is already DNS service is running on the VPS server on port 53. and i can only use 53 port to bypass the limitations as i think. and i can not run openvpn service on my VPS server on port 53. so how to scan the wifi for vulnerable ports like 53 so that i can figure out the magic port and start a openvpn service on VPS on the same port. ( i want to scan similar vulnerable ports like 53 on cyberoam in which the traffic can be tunneled, not want to scan services running on ports). improvement of the question with retags and edits are always welcomed... NOTE : all these are for Educational purpose only, i'm curious about network related knowledge.....
