  • private subnet nat (openvpn / racoon)

    - by Jonas Schnelli
    I have a openvpn subnet 10.8.0.0/24 running one server and one client (laptop). openvpn works fine. Browsing the web over openvpn from the laptop works also fine. Now on the server there is a private subnet with 10.7.8.128/28. The subnet is set up with racoon (IPSEC s2s vpn). The s2s vpn allows me to access the subnet 10.3.5.0/24 at the other s2s vpn end. Works all fine when I'm connected with ssh to my server. From my laptop i can ping 10.7.8.129 (the servers ipsec local ip) but i cannot reach the net 10.3.5.0/24. I tried to add a static route on my laptop 10.3.5.0/24 over gw 10.7.8.129 with no success. Any ideas how i do setup the nat / routing? Thanks

  • localhost works 127.0.0.1 does not IIS

    - by NickatUship
    Very weird problem on IIS. Never had it before: localhost works, but 127.0.0.1 does not. localhost pings to 127.0.0.1. www.mydomain.com also pings to that IP, which is set up in the hosts file, but that also doesnt work locally. I've ipconfig /flushdns 'd without success. Ive even restarted the server. Another server set up the exact same way works fine. Any ideas? To be clear, im accessing the URLs in IE like this: http://localhost http://127.0.0.1 http://www.mydomain.com I can telnet to port 80 without a problem for all 3

  • Using a Dell PowerConnect to set up load balancing/redundancy, 1 switch 2 routres 2 private wan link

    - by MarianoC
    Hi, We have different locations connected by two different WAN providers. Each site has a dell powerConnect 6224 and two cisco routers with the WAN connections (we don’t have access to router admin). The 6224 connects to each cisco LAN port and to our LAN backbone. We would like the 6224 provide the ip gateway address and load balance and support redundancy, if one of the routes fail. Is this possible?. We can't find any samples on doing this and we have tried with no success. Any help or link to documentation regarding this, will be greatly appreciated. Thanks, MarianoC

  • Lenovo tools for windows 7: can't re-enable wireless

    - by pcampbell
    Consider a netbook - Lenovo S10e with Windows 7 and the S10 Lenovo power management tools. Machine has factory BIOS. Fn+F5 is the key combo to toggle the wireless radio on/off. The tool allows the disabling fine; works as expected. The problem is that the re-enable doesn't work, or is confusing on how to re-enable. Previously tried without success: Fn-F5 Fn-Ctrl-F5 Fn-Shift-F5 Fn-Alt-F5 Here's the onscreen display: Question: How can you re-enable the wireless radio using the Function key on a Lenovo netbook?

  • What's the best way to block IP spoofing on a layer 3 switch?

    - by toupeira
    We're hosting Dedicated Servers and are currently using old 3com switches with IP-based ACLs. So each port has an ACL that allows all IP addresses assigned to this customer, and blocks everything else. But now 3com was bought by HP, and the follow-up model only supports basic ACL that aren't flexible enough to both allow certain IPs while blocking others. Looking at other switches in a similar price-range, we've found that most of them have similar problems or don't offer any ACL features at all. I assume this could also somehow be done with VLANs, but if I understand this correctly we'd still need some kind of ACL to actually specify the valid IP addresses for each port. What do you use to make sure your customers don't use unassigned IP addresses? Or what switches can you recommend that have flexible ACL functionality?

  • Scripting help - need to get phone number of AD accounts and then add them to contacts in trusted domain

    - by TheCleaner
    I have domain accounts that I have created as contacts in another trusted domain so that they can see them in their Exchange GAL. I need a way to extract the phone number field from UserA (user account) in DomainA and import it into UserA (contact) in DomainB. I get the logic, it's just the code (vbscript/powershell/whatever) that eludes me. The logic as I see it: Connect to source AD (ou/subtree) Extract user accounts from OU and subcontainers including first name, last name, display name, and phone number Connect to target AD (ou/subtree) Verify/match contact with extract in #2 above based on display name Update phone field with phone number in extract Write log of success and failures Anybody able to help?

  • On Windows 7, how can I tell if a recording is multi-channel without third party tools?

    - by engineerchuan
    A customer has an audio that is confidential and can't send it to me. He also would not like to install other tools. He has a basic Windows 7 install. Is there any way to tell whether the recording is one channel or two channel? Normally, I would just get the audio and soxi it. Or, I would tell him to install Audacity or equivalent sound editor and open it up. I also thought that if you right clicked and looked at the size, bit rate, and length, you could get number of channels but bit rate already factors in number of channels. Sorry I'm not giving you a lot to work with.

  • 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.)

  • Unidentified network: How to configure TCP/IPv4 for Win7?

    - by Zolomon
    When I try to connect to internet I keep getting the error "Unidentified network". I've tried numerous attempts at restoring access without success. IP release, flushing DNS cache, reinstalling NIC, reactivating NIC, resetting router and so on... I've read several times that it's my default gateway that's wrong. Currently I've had automatic IP/DNS configuration set without any problems, and then it stopped working for some reason. Anyone know how I specify the IP? My subnetmask is 255.255.255.0, default gateway is 192.168.0.1 but I have no idea how to determine what IP I should set. I use a D-Link DIR-655 and other computers on the network have IPs like 192.168.0.194, next is 192.168.0.197. (I'm completely lost and am trying to cool down after two weekends of debugging filled with despair.)

  • What is a descriptive name for a web service that responds with plain text?

    - by Rich Shealer
    I'm looking for the proper name for a web service that responds with text as opposed to XML. As an example this "cardServer" service will return 5 cards for a poker hand. http://hostname:8080/cardServer/deal/Game=Poker&Qty=5 The result could look like this: Card1=Ad Card2=Kc Card3=Ts Card4=5d Card5=3d The real world example is not as trivial, but the concept is the same. Parameters if any are passed as POST variables. We currently parse the response into a string list and use the values. The process works just fine. What I'm wondering if this service method has a name that has easier tools to deal with the responses and therefore did we reinvent the wheel? For the record the service was provided and maintained by a customer.

  • Backing up data (including mysqldumps) to S3

    - by seengee
    We have a web app on a number of servers and we want to add an additional layer of redundancy by backing up the key data to S3. The key data is the MySQL database and a folder containing dynamically created site assets - predominantly images. Some kind of rsync based solution would initially seem the best plan. A couple of years ago we played with S3cmd (in particular s3cmd sync) with some success but we didn't find it particularly reliable although this may have changed since. Its occurred to me though that a rsync solution might not work particularly well with a single db.sql file created with mysqldump and I assume this means the whole database getting transferred each time, with multiple databases of over 1GB this is going to add up to a lot of traffic (and $s) very quickly. With the image files I could simply just transfer files modified within the last day which would be far more simple. What approach should I look at?

  • design question for transportation agency/workflow system

    - by George2
    I am designing a transportation agency/workflow system, and it including 3 types of people, customer who requests to transport some stuff, drivers who deliver the stuff, and truck manager who manages transport source/destination truck coordination and communicates/organizes drivers. The system is expected to be a web site, and 3 kinds of people could use the web site to submit request, accept request, monitor status of specific stuff transportation, etc. The web site is more like an open agency or a workflow system. I am wondering whether there are any existing technologies, tools or projects (better to be open source, but not a must) which I could build my application faster based on? I prefer to use .Net technologies, but not a must. Thanks in advance!

  • 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?

  • Conflicts with MS Office temporary files when using Offline Folders on Vista

    - by Tambet
    We are using Offline Folders feature of Windows Vista to make files on network shares available when out of office. Mostly it is working, but every time I do a sync I get a lot of such errors: D500E7B8.tmp - A file was deleted on this computer and changed on the server while this computer was offline. There are hundreds of them. I always select all of them and choose resolution "Delete from both locations". But what is causing this and how can I avoid it? I suspect the reason is that we are using Debian and Samba (3.4.7) on our file server. I've been looking for some Samba options that would cure this, but with no success. I learned that probably the cause is, that both Word and Excel are using specific pattern to change files - they never change the original file, but instead always write a new temporary file and rename it to original file, when you click Save. This is documented here: http://support.microsoft.com/kb/211632/?FR=1.

  • How would I measure the amount of RAM needed per Glassfish domain? [closed]

    - by oligofren
    Possible Duplicate: Can you help me with my capacity planning? In our test environment we have a lot of apps spread out over a few servers and Glassfish domains. To make versioning easier I would have liked to have one Glassfish domain per customer per app (kind of like a heavyweight version of lots of jetty instances). But I have heard that Glassfish is kind of heavy on the resources, and so I would need to measure approximately how many instances would fit in the available RAM. These are low-traffic/low load testing servers, so CPU is not really an issue, though RAM might be. How would I get an approximate measure of how much RAM is needed? This is one Glassfish 3 instance with one heavy EAR application deployed. top? jvmstats? ??

  • Reccomendation for tuning 100's of SQL Databases

    - by wayne
    I'm running several SQL servers, each running a few hundred multi-gig databases for customers. They are all setup homogeneously as far as the schemas are concerned, however customer usages of the data differ quite a lot from database to database. What would be the best way to auto-index/profile/tune this large amount of databases? As there are at least 600 or more catalogs I cant have someone manually profile, and index as required by each databases usage patterns. I'm currently running SQL 2005 but will be moving to 2008, so solutions that work with either are fine.

  • BSOD doing wireless connection repair

    - by Kb
    (This should maybe be asked on Super User, but currently it is only for beta users.) We have a Dell Latitude X1 which always gets a BSOD (page fault in non page area) after repair on wireless. Wireless works as long as we do not do repair. Have tried the following with no success: Have updated BIOS to latest version and updated drivers for Intel wireless to the latest version. Any other suggestions? For now we just do not do repair and maybe that is the solution?

  • java will this threading setup work or what can i be doing wrong

    Im a bit unsure and have to get advice. I have the: public class MyApp extends JFrame{ And from there i do; MyServer = new MyServer (this); MyServer.execute(); MyServer is a: public class MyServer extends SwingWorker<String, Object> { MyServer is doing listen_socket.accept() in the doInBackground() and on connection it create a new class Connection implements Runnable { I have the belove DbHelper that are a singleton. It holds an Sqlite connected. Im initiating it in the above MyApp and passing references all the way in to my runnable: class Connection implements Runnable { My question is what will happen if there are two simultaneous read or `write?

  • Proccess of carrying out a BER Test

    - by data
    I am subscribed to an ISP supplying a 3meg ADSL line. Lately (for the last 4 weeks) speeds have dropped from the usual average downstream speed of ~250kbps to just 0.14Mbps (according to speedtest.net) and employees are complaining about lack of access to the server. I have been calling customer support and logging calls for the last 3 weeks, but they have been unable to determine the source of the problem other carrying out a few bitstream tests and checking the DHCP renewal times. I am going to call back and suggest carrying out a BER test. What type of equipment is needed to carry out this test? I have access to a wide range of Cisco networking equipment. Other: We dont need a leased line as there are less than ten employees.

  • dd cloned win2003 std ntfs partition, "no operating system found".

    - by 3molo
    I cloned an existing ntfs partition on faulty hardware using dd and gzip. The copied partition was then written to a newly created ntfs partition on a new disk (on another server) and the bootable flag was set. However, the "Operating system not found" (or is it No operating system found?) is what happens when I try to boot it.The faulty server is part of the AD domain, but I do not have the local administrator password, so I couldn't use the repair console of windows 2003 to fixmbr. I did try to do a normal repair during win2003 installation menu, but with no success. Both windows installation and Linux recognizes it as a ntfs partition of its true size, and files can be seen and read. I've done this a couple of times before, but I didn't encounter this problem. Of course I encountered other problems, like BSDO due to lack of hw drivers etc - but that was pretty easily fixed. Why am I failing to get the copied partition to even be recognized as a bootable disk on the new server?

  • Disable "Print and Close" Preview Shortcut on OS X Mountain Lion (10.8.2)

    - by Twitch_City
    I recently upgraded to Mountain Lion from Leopard and there is a global shortcut that I would really like to disable. Apparently, now if you select a document and press Command + p, Preview will open, print the document, then close. I'm sure this was done with the purest intentions but, unfortunately, it is right next to Command + o, which I use many times a day to open files. Since installing Mountain Lion, I've accidentally printed way too many documents just trying to open them! I've gone into the Keyboard preference pane and tried to find where this shortcut is located, but haven't had any success. Anyone know how I can disable this?

  • PowerShell script halts execution when Windows XP PC is locked

    - by jshin47
    I have the following script that does a continuous ping and reports failures. It works fine, except the loop apparently "suspends" when the computer is locked. I have confirmed this by starting the script, immediately locking the PC, waiting 10 minutes, and seeing how many pings have occurred. It is nowhere near the expected number.

  • Remove DRM From a WMV file I own

    - by Rev
    Alright, first, let me explain. I purchased some content through Microsoft's Zune/Xbox Video service, and man that was a mistake. After trying several times to get the video to play, I received an error along the lines of "out of licenses." Lucky for me, I was able to recover the file I was looking for off of a backup, but now I'm having problems playing it. It works fine in Windows Media Player, but not in Zune or Xbox Video (on Windows 8). I contacted Zune's customer support, and of course they couldn't help me. So, I legally own the content, I just want to be able to play it where I want to play it. It's ridiculous that I can't. I know there are ways to do this out there, I just can't figure it out (I keep getting directed to this piece of junk thing called Almedia, which kind of seems to work, but was only putting out audio in the demo version). Thanks!
