• How configure 2 Lan cards in Windows 7/8 pc one to connect to Internet and other to Local Network

  - by Maharshi Raval

      I am about to install a dedicated VOIP server in our office. It is a 3CX pbx system on Windows 7/8 machine. The environment currently is a Windows SBS 2011 with 8 client machines. I want to use a dedicated broadband connection for the PBX (3CX) box, but the box also needs to be accessible in the local network as we will be using IP Phones and software IP phones. How configure two network cards on PBX box, so that one will be always used to connect to our SIP host over the Internet and the other will be connected to local network accessible from other client pc to connect to the pbx system. It must be noted that currently the Windows SBS 2011 acts as the Primary Domain Controller and gateway for all the client machines.     I cannot use a load balancer as it will conflict and cause issues within the current setup of our SBS2011 as it is also our Exchange Server. Any input is much appreciated. thanks in advance

• What is it safe to let Revo Uninstaller cleanup leftovers?

  - by msorens

  I have been a user of Revo Uninstaller (free) for sometime and find it does a very good cleanup job with typical applications. Today I wanted to clean up my machine a bit more so I proceeded to remove Visual Studio 2005 with Revo Uninstaller. The VS installer removed the app with no issues, then Revo reported about 20,000 leftover registry keys. I am used to basically just see Arpcache and Muicache... since I am not a registry expert I had no clue about most of the 20,000 listed. So I backed up the registry then let Revo remove the 20,000. It next reported about 1500 leftover files which included my Microsoft Office applications(!) that I knew it should not be touching. So I did not delete any files with Revo. Suspecting that some of the removed keys were also Office-related, I tried to open Word and Excel, both of which knew something was up, as the installer kicked in (albeit just briefly) for each of them. At this point, since I knew there were issues, I just restored the registry and I am now (seemingly) running OK. My question, then: When is it safe to trust Revo Uninstaller? As a seasoned software professional, my own answer to this would be the obvious "When the keys it reports are something you understand and know are safe to delete" but then that makes Revo of little use except to registry experts, does it not...?

• Edubuntu video playback and apt-get

  - by asdasd

  They had installed some modified edubuntu's at school... So i have some questions about setting some things up: How we can play HD videos ? They are made for windows machines and are in .wmv format but we need to play them on our multimedia class but don't know how - which player, which codecs etc. How to edit properly the /etc/apt/sources file ? Anything we try to install via apt-get it just says that E:\ is not available. Please tell me which repositories to put in there so we could be able to install some tools. Where are usually viruses/trojans put in ubuntu ? I mean in which directories ? Because our computers are behaving really slow and we need to check for some malware manually - we are not even allowed to install any kind of AV software. So tell me the usual directories and places for hiding such files, how are they hiddem, how to recognize them etc. Any others nice tricks/tips that we need to know. Thank you very much in advance.

• Network connection keeps dropping - bad hardware?

  - by Bill Sambrone

  Hello all, I've into a bit of a wall with a client of mine. In an office of 20 people, he is the only one who experiences broken connections to his mapped network drives. I have everyone set up with about 6 mapped drives, all pointing to the same server (no DFS), and everyone else can access them lightning fast. The environment consists of a mix of Windows 7 and XP machines, all 32-bit. The server holding the data everyone is mapping to is running on Server 2008 R2, and is a domain controller. We recently swapped out their old 10/100 switch for a shiny new Dell PowerConnect gigabit switch. We have also replaced an old dying Sonicwall with a shiny new one. Everything is running on an ESX host except for the DC, where everyone is getting data from. In my client's office, we have done the following: Swapped out his computer (Win7 and XP box) Swapped out the desktop switch in his office Removed the desktop switch in his office Changed out the network cable going to the wall Ran 'net config server /autodisconnect:-1' on the server Disabled remote differential compression on his current Win7 box When we swapped out his network cable, everything seemed fine for about 4 days. Normally I would get a phone call a couple times per day letting me know that Outlook has crashed (there is a 9GB PST living on the server he is always connected to), or that his software he is running from his L drive has crashed. I almost thought I had this solved, but after we rebooted the DC the other night he all of a sudden couldn't stay connected to his mapped network drives for more than 10 minutes. When I ran 'net use' from the command prompt, it listed all the network drives where were randomly in a state of 'OK', 'Disconnected', or 'Reconnecting'. What else should I try? Maybe there is bad wiring in the wall, patch panel, or a bad port in the new switch I have in the server room?

• Creating a bootable USB drive from a distro split over two DVD ISOs

  - by Kev

  I am searching and not finding the right way to do this. Please note, I don't think I'm trying for anything strange here. I just want to make a bootable USB stick of a single OS that happens to be larger than one DVD and happens to be larger than FAT32 will allow for in a single file. On our slow connection I spent a long time downloading CentOS 5.9's two DVD ISOs: CentOS-5.9-x86_64-bin-DVD-1of2.iso (4.4 GB) CentOS-5.9-x86_64-bin-DVD-2of2.iso (718 MB) I have a USB stick that I want to somehow get these two ISOs on. Since the first one is 4.4 GB, I can't use ISO2USB because it insists on FAT32. I cannot find an alternative that lets you specify more than one ISO image--of the same distro, I'm not trying for some fancy multi-boot thing--to put on the same stick. I guess I should have downloaded the CD ISOs, but I thought I was "saving time" because then I wouldn't have as many files to run through the md5 checker. There's no IMG file of the whole thing (only a net install version, which I don't want--I want to pre-download everything) otherwise I would've gone for that. So, given that I have these two DVD ISOs, how can I get them on a stick that will boot and make use of both of them properly to install CentOS somewhere? Again, I don't think this is anything out of the ordinary, yet I can't find software/docs that seem to support this. Am I stuck re-downloading everything in CD-sized ISOs just to do this? I found this, but it doesn't run on Windows. I am using Windows to prepare the stick.

• Tables in the SQL Server "master" database, will they cause problems?

  - by pepoluan

  Folks, please be kind on me... I'm just an 'accidental' DBA due to our DBA resigned, so I'm totally a newbie in DBA... You see, I have this application, "ESET Remote Administration Server" (ERAS) that stores its logs and analysis on (originally) a local Access database. The decision was to migrate its database to a SQL Server 2008 R2 machine. ESET (the maker of the software) helpfully provided tools to perform such migration; unfortunately, being the DBA neophyte that I am, I didn't realize that I have to first create my own database (on the SQL Server side) and assign that database as the 'default' database for ERAS' ODBC connection. Now, the migration tool had successfully created a whole bunch of tables inside the "master" database. My questions: Should I leave things be as it is, or should I re-migrate the ERAS database to a different database? If you suggest me perform a re-migration, my plan is to (1) create a new instance, (2) create a new database within the new instance, (3) create a new ODBC System DSN on the ERAS server pointing to the new DB in step 2, (4) use ESET's migration tool to migrate from the current DSN to the new DSN. Do you think I missed a step there? Thanks beforehand for any guidance.

• Standards for documenting/designing infrastructure

  - by Paul

  We have a moderately complex solution for which we need to construct a production environment. There are around a dozen components (and here I'm using a definition of "component" which means "can fail independently of other components" - e.g. an Apache server, a Weblogic web app, an ftp server, an ejabberd server, etc). There are a number of weblogic web apps - and one thing we need to decide is how many weblogic containers to run these web apps in. The system needs to be highly available, and communications in and out of the system are typically secured by SSL Our datacentre team will handle things like VLAN design, racking, server specification and build. So the kinds of decisions we still need to make are: How to map components to physical servers (and weblogic containers) Identify all communication paths, ensure all are either resilient or there's an "upstream" comms path that is resilient, and failover of that depends on all single-points of failure "downstream". Decide where to terminate SSL (on load balancers, or on Apache servers, for instance). My question isn't really about how to make the decisions, but whether there are any standards for documenting (especially in diagrams) the design questions and the design decisions. It seems odd, for instance, that Visio doesn't have a template for something like this - it has templates for more physical layout, and for more logical /software architecture diagrams. So right now I'm using a basic Visio diagram to represent each component, the commms between them with plans to augment this with hostnames, ports, whether each comms link is resilient etc, etc. This all feels like something that must been done many times before. Are there standards for documenting this?

• Relaying to tech "support" that computer is actually broken.

  - by Sion

  First some background: I have a Dell Inspiron 15R M050, it is still under the Dell limited warranty and the Best Buy Extended warranty. I am currently dual booting Debian Squeeze and Windows 7, the only reason I go into Windows is to play video games specifically steam games. Issue: When I play my games in Windows I am capable of playing for anywhere from 5 minutes to 2 hours before I suffer a hard-lock. I cannot alt-tab, ctrl-alt-delete, ctrl-shift-escape do anything for 2-3 minutes. After this hard-lock period everything runs fine, I can continue the game for probably another hour at least before I suffer another lock. Games: Borderlands, Splinter Cell: Chaos Theory, Starcraft 2, Garrys Mod What I have tried: Running the diagnostic suite in the dell bios, restoring the OEM Windows recovery partition on the HD, fresh installing Windows 7 Professional, updating BIOS, Calling tech support and having them run a software Hardware Diagnostics suite. The question: I think from the research that I have performed that it might be a lack of thermal paste on the CPU, would I be able to go to Best Buy and have them do a hardware diagnostic from the hardware level then have them be able to tell Dell that there is a hardware issue? Or would there be a different problem?

• Slow Local Network, Windows 7, Snow Leopard, WiFi/Wired

  - by WerkkreW

  I am experiencing really poor local network performance in my home. I was recently using a Linksys WRT54G Router with DD-WRT on it, and a couple comparable Linksys-G PCI cards for connectivity but decided to upgrade hoping it would help with my performance issues. The computers in my house are connected as follows: Comcast Business Class Commercial 25mbps/10mbps (Verified) D-Link DGL-4500 Wireless N Router Windows 7x64 - D-Link DWA-552 Wireless-N Windows 7x64 - D-Link DWA-552 Wireless-N Mac Mini 10.6.2 - AirPort Extreme N Playstation 3, Hard Wired Xbox 360, Hard Wired Essentially the problem is very specific. Web browsing and uploading/downloading files from the internet is fine, more than fine. But if I want to say, Stream a video from one of my Windows 7 computers to my PS3, or copy a large video file between either of the PC's or the Mac, I get a consistent 500-900Kbps throughput at the high end. If I open my network browser, or try to browse my homegroup the response time is horrible. Both of my Windows computers are showing Strong wireless signals with a connection speed of 300Mbps. I know I can never expect to achieve anything near those speeds, but 500Kbps? Here is what I have tried so far: Enabled Single mode N-only and N/G Only on router WPA2 with AES Encrpytion Disabled "Remote Differential Compression" in Windows 7 Disabled TCP "Auto-Tuning" Used other software for file copies such as "Teracopy" I am at the end of my rope. Unfortunately I live in a 75 year old home with plaster walls, so hard-wiring my entire house isn't really an option I can handle right now. Any ideas to help me get decent speed when transferring files across my network would be greatly appreciated.

• Max. Temp. on Intel Burn Test for Stock Dell Precision T3500

  - by HK1

  I'm troubleshooting an issue on a Dell Precision T3500. As part of my troubleshooting I've decided to try running a stress test using Intel Burn Test software. This machine is a stock configuration with 12GB of RAM and a Xeon W3670 processor (nothing overclocked). When I run IBT using the standard mode, SpeedFan reports a processor temperature in excess of 80C. I've seen numbers as high as 90C but even at that temperature the machine does not become unstable or crash. However, it seems way too high. This processor has a TCase of 67.9C according to Intel's website. I'm guessing that means I'm in the danger zone any time I go over that temperature. I've checked the cooling system and everything looks fine. I've even took out the heat sink and reinstalled it with new thermal compound. This did not appear to make the problem better or worse. Is there a discrepancy somewhere here in the way temperatures are measured or displayed? I've also tried using HWMonitor from CPUID and it reports the same temperatures. Should I just let the Standard Test go and disregard the temperature outputs?

• Should I embed the sRGB color profile in JPEG files?

  - by basic6

  I have a large (growing) collection of scanned images. They are TIFF files, mostly 48 bit with the Adobe RGB color space. This color profile is integrated in the files. When such a file is opened in IrfanView (with plugins), it says (Image - Information) Adobe RGB 1998. "Normal images", like the JPG files from a digital camera, do not (necessarily) have a color profile integrated in the file. I understand that it's necessary to include the Adobe RGB profile in an image file which uses the Adobe RGB space, so the color values can be interpreted correctly. Here's a test image with a completely different color profile, programs that ignore the included profile (like MSIE8 or Gwenview) will render it as sRGB (?): I'm planning to convert my TIF files to JPG, so I'm wondering if there's anything wrong with using IrfanView that would save them as sRGB without embedding the sRGB profile. I've heard that images should always be saved with the color profile included. Since every image seems to be interpreted as sRGB by default (by software without color management), I don't understand why the sRGB profile should be included?

• Computer sponteously reboots when doing heavy file copy to/from disk

  - by Mark Hosang

  I've been fighting with this problem for the last 3 weeks where my machine will just instantly reboot. No BSOD, and when i checked the event log all that was reported was the generic "Kernal-power" error with the detailed information pointing to a hard crash. This is a machine that was working for 18 months before these crashes started happening. When they started happening is after I added 3 HDs in a RAID-5, upped the memory to 12gb, moved to a new house, added a SSD and added about 5 case fans. I have thus eliminated the RAID, and determined that the SSD was not the cause (because it was still crashing even though the ssd wasn't connected). I've run memtest several times over night with no memory problems showing up. I've run IntelBurnTest to max out the cpu to see if it was a heat issue and at full tilt after 20 min it was only at 85C and the machine didn't crash. I also took a look at the voltages during this test, with a screenshot at the bottom of this post I've ruled out a software issue by reinstalling windows 7 ultimate x64 a total of 5 times, but even during that the install it crashes. Happens sometime during file copying at the beginning, or during uncompressing files, or sometimes during running windows update. The only discernible pattern i can see is that it seems to crash when hard disks might be spinning up or when they are accessed heavily from large file transfers. My current guess is that it is probably an issue with the MB, PSU or the power coming through the outlet. Any suggestions of what i could try to troubleshoot or what may be wrong? Specs PSU: Seasonic M12 700w Mem: 12gb CPU: i7-920 with stock heatsink MB: Asus P6T HDs: 3 green WD and 1 Corsair force 3 120b with 1.3.3 firmware Running full tilt voltages Idling Voltages

• Erratic WiFi 2.4 GHz channel spikes, what gives?

  - by Francis W. Usher

  Sorry guys, first a gripe about my neighbor's WiFi access point (it is related): they totally hog the center nine 2.4 GHz channels (3-11), centered right at 7! I know the outer regions of the signal don't make as much of a difference, and technically they're running channels 5 & 9. Anyway, their signal is clearly interfering with mine, which is necessarily centered at 3 or 11 to evade their interference. I guess it's somewhat a case of access point envy: they happen to have both a stronger signal and a higher data rate, while occupying twice the band width that I do. Getting to the point, I've noticed that they tend to sit nice and pretty centered at 7, but they definitely auto-select their channel, and I've noticed that the auto-selection algorithm tends to shift towards the higher channels; hence I decided to pick channel 3, and I don't get so many intermittent lag spikes any more. Anyway, the thing that weirded me out was the reason they have to auto-select sometimes: unexplained, powerful (talking order of 0dB here), giant spikes of 2.4 GHz activity in consistent regions of the spectrum. I don't think it's just noise, since my wireless monitoring software is registering a MAC address, a manufacturer, and usually a fairly coherent ascii name... and it seems to be a fairly well-confined signal. But these signals are fairly common, and they do some weird stuff to my signal. So my question is what are these signals? Where are they coming from? Where are they going? Why are they so ridiculously strong? Why don't they ever last very long? Here's an inSSIDer screenshot I took, for your perusal. I am labeled with "me", my greedy neighbor labeled with "neighbor", and the 2 quasar signals are labeled with "WTF?".

• How to organise storage for media content such as video and music?

  - by thor

  Currently, we have a single server hosting all content: music, video and software. This content is downloaded by users through HTTP. Now free space is coming to an end and we are exploring different ways of extending our storage capacity. We want to do it cheap, simple and reliable (protected from disk/ server faults). Currenly, we see two ways: Add a couple of cheap servers with 4 disks (RAID1 ?), run some distributed file-system on top, like GlusterFS. Pros: hopefully, we will see all our disks as single flat file system, just dump content into it and be done. Cons: could be tricky in configuration and handling of faults. Add a couple of cheap servers, all running HTTP servers. Each piece of content (be it a music file or video) is placed on randomly selected two servers. Pros: don't have to deal with RAID, as content is duplicated; single server failure does not bring down any part of content; doubled distribution capacity (as any signle file could be downloaded from any of two servers hosting it). Cons: requires some scripting on part of distribution of content, adding/ removing servers. Do we miss any other ways? Which of the aforementioned options seems to be the best?

• Windows 7 ignores F6/F8 and will not boot

  - by P.Brian.Mackey

  I have a work PC with sophos safeguard encryption on it. Windows failed to start. When I bootup I receive an error saying a recent hardware or software change might be the cause. File: \Boot\BCD Status: 0xc0000098 Info: The windows boot configuration data file does not contain a valid OS entry. This began after the PC forced me to run a system recovery. My machine had powered down improperly (power outage?) and simply would not respond to my keyboard input to cancel the option to scan my system. After the scan "repaired" a boot file, my system crashed. Now it tells me I can insert my windows 7 disk and run recovery. I can't simply do this because of Safeguard. The system recovery can't see my encrypted drive. I tried hitting F2 to manually login to Safeguard and then selected the option to boot from media. The computer prompts me to hit any key to boot from disk...which I do, but once again it is not reading my keyboard input. I can't get F8/F6 to bypass startup files and get me to a command prompt like the old days. If I could get to a command prompt I might could recover the file windows jacked up from its backup location...though I may need to use the windows recovery disk UI to do this..??? In the past I've been able to slap in a PS/2 keyboard when the USB keyboards stop responding like this. I have no PS/2 keyboard available. Anyone have any idea how I can undo the damage windows system recovery has done with safeguard installed?

• Create a PDF that defaults to flip on short edge when printed double-sided

  - by user568458

  We're creating a 2-page PDF brochure with a target audience who will print it on their regular office or home printers. If it is printed on a double-sided printer (common in offices), it'll come out correctly if set manually by the user to "Flip on short edge", but will come out with the second page upside down if default settings are used (flip on long edge). Our target audience aren't very tech-literate, and we've found that even within our own office network there is variation in the location of the 'Flip on short edge' setting - so it isn't realistic to give everyone who downloads the PDF instructions on how to change this setting or to expect everyone to find out how to change the setting off their own backs. So, when creating a PDF (ideally using Adobe InDesign or Acrobat, but if other software or hacking is needed that's fine...), is there a way to configure the PDF file itself so that when printed double-sided with default settings, it flips on the short edge? If possible, it'll be useful supplementary info to know how reliable any such methods are across different PDF readers (e.g. Adobe Reader, Acrobat, Mac Preview, inbuilt browser readers (e.g. chrome), FoxIt, etc). If questions about content creation like this aren't a great fit here, feel free to migrate it to the graphic design stackexchange site - this question seems to fall half way between the two sites

• How to increase the speed between two external hard drives on my laptop?

  - by Roman

  Hello, I own Sony Vaio Z laptop with two external USB ports. It's quite new and has USB 2.0 support. I'm using Vista x64 on it. I also have two external usb hard drives, Iomega 500GB and WD for 1TB. Every hard drive has USB 2.0 support. I connect two devices to my laptop and trying to copy date from one hard drive to another. But it takes a lot of time! The speed is about 15 Megabytes per second. I have to wait toooooo long to copy all the information from one hard drive to another. When I try to copy information from my internal (SSD) hard drive, it works fine for both external drives. The speed is very high and it shows me something about 100 Megabytes per second. It makes me feel that USB 2.0 is OK on both drives. But when I'm trying to copy from one external drive to another external, I still get very low speed. I checked out Device Manager and here is the settings I have: (sorry, can't upload image because of my rating, check this url: http://picbite.com/image/122073daljo/ ) I think it's because two of my external drives use the same USB 2.0 controller. Is there any way to make it work faster? Is it possible to move one of my USB ports to other USB 2.0 controller? Or is there any software which can help me to automate copying all the files thru my internal drive? I have only about 3 gigabytes free space on internal drive and it's quite difficult to move manually every file from one hard drive to internal and then again to another internal.

• How should a small company administer their web server?

  - by John Isaacks

  We currently have our website hosted by a small company that is actually a reseller for Rackspace. They act as our server administrators. They configured the servers, handle the backups, if there is a problem, we call them and they fix it. We are growing and want to move away from our shared server to either a cloud or dedicated server. I am thinking cloud myself but I am open to either. The current company doesn't seem to want to offer us anything more than a shared hosting plan. I looked into cloud solutions at vps.net, with them I would have to be the server administrator myself. I am the website programmer but administering the server is outside my comfort zone. vps.net does have a $99/month plan for Pro-Active Managed Support but I am not sure if this is the equivalent on a server admin that is there when you need them. We could hire someone in house, but I think that would be overkill for our needs. I am not exactly sure what we need, I do know we need as close to 100% uptime as we possible can. and we need the ability to add/remove/change the server configuration/software/etc. when needed (though changes shouldn't be very often once everything is setup right). Can someone point me in the right direction? What do other companies do?

• All of the NTFS hard links damaged, where are hardlinks stored and how to recover them?

  - by String Xu

  This is Windows 7 x64 sp1 on a NTFS file system. All hardlinks within C:\Windows\System32 folder disappear, and the Windows can't boot, because even the osloader, C:\Windows\System32\boot\Winload.exe also disappeared. Nevertheless, the original files are still located in the corresponding C:\Windows\winsxs folders. After booting into the Recovery Environment, and copied one Winload.exe (x64) from other folder, Windows gave an error pointing out that "ntoskrnl.exe is corrupted or missing...its file digital signature cannot be verified" In trying to boot in Safe Mode, the message above was shown after a screen prompting "Loaded \Windows\system32\config\system" Because at this early booting stage, smss.exe was still not loaded, so there is not any dumping and logs. Based on my study, ntoskrnl.exe depends on the following files: C:\windows\system32\PSHED.DLL C:\Windows\System32\hal.dll C:\Windows\System32\kdcom.dll C:\Windows\System32\clfs.sys C:\Windows\System32\ci.dll All those files above are copied from their corresponding folders and verified their md5 with a well-operating Windows 7 x64 SP1. But the booting error is still the same: "ntoskrnl.exe is corrupted or missing..." Background: 1. Before the reboot, there was an windows update going on. Then something unknown happen, almost all processes were broken to run, including the windows task manager, taskmgr.exe. After mount the hard disk to other computer, it seems that all hardlinks within C:\Windows\System32 folder were gone. I tried several data recovery software, but they are not be able to find those disappeared NTFS hard links. So the question is: Where are information about those hard links stored? And how to recover them? Are they depend on some windows service or stored in the registry?

• Thomson router reboots unexpectedly with an apparent remote connection attempt

  - by ChrisF

  I've got a weird problem. Every so often my rooter (a Thomson TG585 v8 running version 8.2.7.8 of it's firmware) reboots itself. It seems to be associated with this message in the event log: FIREWALL replay check (1 of 2): Protocol: ICMP Src ip: 183.178.144.177 Dst ip: xxx.xxx.xxx.xxx Type: Destination Unreachable Code: Host Unreacheable xxx.xxx.xxx.xxx is my external IP address 183.178.144.177 resolves to 183178144177.ctinets.com We've got a student from Hong Kong staying with us at the moment and the reboots seem coincidental with him starting up his laptop. I say this because a check on ctinets.com shows it to be based in Hong Kong, though our guest's laptop doesn't appear to have any software related to this company installed. I say "apparently" as he is running the Chinese version of Windows and his English doesn't cover technical subjects like this. I know this is an incoming message but I was assuming that it was in response to something on the student's laptop which is why the first thought was malware, but we've got anti virus on all the other machines and have run malwarebytes on his with a negative result so I don't think the problem is due to a virus or (known) trojan. What else can I do to stop this and identify the cause?

• Connect trough remote computer connection

  - by Didac

  First, sorry for my english and my poor knowlodge of this subject. I have a dedicated server placed in Germany (windows 2008 R2) and I live in spain. I would like to access internet from my home computer (Windows 7 Pro x64), trough my server in Germany, so I can use a German IP, what I need some times. I have complete acces in to both computers, but I just don't know where to start. (My knwoledge is limited to software development :/ ) I'd like to know where to start, if I need to create a VPN and so.. Thanks in advance! Update 1 I tried a lot of options of OpenVPN, but I sadly I know nothing abuot networking, so I have to accept I do not know what I'm doing :( Here are my config files (note most of the options are from the sample config files). server.conf #server config file start port 1194 proto udp dev tun server 10.0.0.0 255.255.255.224 #you may choose any subnet. 10.0.0.x is used for this example. ca "C:\\Program Files (x86)\\OpenVPN\\easy-rsa\\keys\\ca.crt" cert "C:\\Program Files (x86)\\OpenVPN\\easy-rsa\\keys\\server.crt" key "C:\\Program Files (x86)\\OpenVPN\\easy-rsa\\keys\\server.key" dh "C:\\Program Files (x86)\\OpenVPN\\easy-rsa\\keys\\dh1024.pem" push "redirect-gateway def1" push "dhcp-option DNS 8.8.8.8" #the following commands are optional keepalive 10 120 comp-lzo persist-key persist-tun verb 5 #config file ends client.conf #client config file start client dev tun proto udp remote 176.9.99.180 1194 resolv-retry infinite nobind persist-key persist-tun ca "C:\\Program Files (x86)\\OpenVPN\\easy-rsa\\keys\\ca.crt" cert "C:\\Program Files (x86)\\OpenVPN\\easy-rsa\\keys\\client1.crt" key "C:\\Program Files (x86)\\OpenVPN\\easy-rsa\\keys\\client1.key" ns-cert-type server comp-lzo verb 5 explicit-exit-notify 2 ping 10 ping-restart 60 route-method exe route-delay 2 # end of client config file And here's the server's network settings: IP address: 176.9.99.180 Subnet mask: 255.255.255.224 Default gateway: 176.9.99.161 Preferred DNS server: 127.0.0.1

• How to reproduce the behavior of Mac OS X's dead keys on Windows 7?

  - by Pascal Qyy

  I'm French, but I've chosen to take a QWERTY keyboard for my MacBook Pro for many reasons: first of all, the AZERTY keyboard is not at all ergonomic because it has no numeric keypad, and I must use MAJ or CAPS LOCK to access to the numeric keys ; secondly, I've bought this mac for development ; and chars {, }, etc., are not directly accessible on the Apple AZERTY keyboard the last thing is that: the diacritics are VERY easy to produce on an Apple keyboard with Mac OS X : ? + c for a ç, for example, and many dead keys easy to use (e.g. ? + e, then e give you an é. So, I have no difficulties to write in my native language with this keyboard under Mac OS X. BUT, when I boot on Windows 7's Boot Camp partition, or when I use applications from it through VMware Unity, it is no longer the same comfort! Without numeric keypad, it's impossible to use it for produce specials characters (e.g.: Alt + 0231 for the ç) I've tried many solutions, like auto replacement in Microsoft Office (e.g.: ,,c being replaced by ç), but for all my diacritics, I must type a space, then a back space before the replacement work. I've also tried third party software, as Texter, but it is very buggy and don't work properly (or don't work at all) in many case! So, is there a solution somewhere, to have this Mac OS X's nice and comfortable way of producing diacritics for Windows 7? Thank in advance for your help and your time!

• Freebsd jail for an small company - checklist - what shouldn't forget

  - by cajwine

  Looking for an checklist for an "small company freebsd/jail server". Having pretty common starting point: FreeBSD jail (remote/headless) for the company: public web, email, ftp server, and private (maybe in the future partially public) wiki (foswiki) 4 physical persons, (6 email addresses) + one admin - others will never use ssh) have already done usual hardening on the host side (like pf, sshguard etc). my major components are: dovecot, exim, apache22, proftpd, perl5.14. Looking for an checklist, what I shouldn't forget. My plan: openssl self-signed certificates for exim, dovecot and proftpd (wildcard keys) openssl self-signed certificate for apache (later will go for "trusted-signed" key) My questions are: is is an "good practice" having one pair of wildcard SSL-certificates for many programs? (exim, dovecot, proftpd) - or should I generate one key for each service? should I add all 4 persons as standard (unix) users, or I should go with virtual users? Asking because: have only small count of users, and it is more simple to configure everything (exim, dovecot) for local users ($HOME/Maildir), plus ability to set $HOME/.forward/vacation and etc. is here some (special) things what I should consider? (e.g. maybe, in the future we want setup our own webmail - will make this any difference?) any other recommendation? Thank you, hoping that this question fit into the http://serverfault.com/faq under the: Server and Business Workstation operating systems, hardware, software Operations, maintenance, and monitoring Looking for an checklist, but please explain why you're recommending it. See Good Subjective, Bad Subjective. related: What's your suggested mail server configuration for a FreeBSD server?

• Production deployment to EC2 with minimal downtime

  - by jensendarren

  I have a simple web application deployed on a large instance with EC2. I now want to deploy the latest code to this server but I want to do this in a way which minimizes downtime and is a smooth as possible for the end user. Here is my plan: Fire up another large instance Install all the software layers on that instance Restore and attach an EBS drive to the instance Deploy our latest production ready code on the new instance Run all tests (including manual testing of the application) (If tests pass) Put a "Site Under Maintenance" notice on the live site. Backup the EBS instance on the live site Detach the EBS instance from the new server and replace with the latest backup Use ec2-associate-address to move the IP address to the new instance Sit back and wait for traffic to start flowing though the new instance Terminate the old instance Does this seem like a good strategy? Are there any tutorials or books that might cover this topic? I have already read Cloud Application Architectures by George Reese, which is an excellent book, but does not cover deployment. Additionally, I know that there are tools that can help with this like RightScale or enStratus which I will use when I start using more than one instance.
