  • Games, Windows 8.1 and 144Hz display

    - by Marioysikax
    So I have been having problems with few games after switching from 7 to 8.1, which seems to be related to my 144Hz monitor. Few examples: Shank, Shank 2, Blood of the Werewolf, Astebreed, the Sims 2 and Rayman Legends patch 1.2Had few other as well but it's been long and I have 600+ steam library. From those games at least the Sims 2 and Shank worked without any problems with same setup and Windows 7. So basically these games simply refuse to launch with basic setup. However if I plug 60Hz TV with HDMI instead everything magically starts to work. As for Astebreed and the Sims 2 using windowed mode seems to also work. As for Rayman Demo and version 1.0 works for some reason and 1.2 breaks settings menu. I have already tried contacting supports. EA support stated game simply shouldn't work with 8.1 at all (which is lie as it works with that TV and friend with 8 plays just fine), ubisoft support took few weeks and support said he will forward info for further processing, blood of the werewolf support had no idea what's going on and told me to just use my TV instead.Changing monitors refresh rate to 120Hz or forcing it to 60Hz doesn't do anything. I have DVI right now but I will try with DisplayPort when I get the cable. At PCGW Garrett said it may have something to do how listing resolutions work with 8 compared to earlier Windows versions but my googling skills don't bring anything up and compatibility mode for earlier windows version doesn't work either (not that I expected that to work). My system specs are on my steam profile. How do I get those work with my 144Hz monitor as well as possible future games having same problem? Downgrading to 7 would work but is far from practical and I don't own legit lisence for that one.

  • RD Gateway reporting features/capabilities

    - by Don
    We have just implemented RD Gateway for our own department in preparation for a push to the whole agency for telecommuting. It is all setup and working great, but I was trying to figure out how best to go about monitoring/reporting of users. I see third party software out there that will do it, but is there anything built-in or via powershell/scripting that I could use that would give me a report of the daily activity of users? Something to say, "User A connected at this time, was on for this long, sent/received this much data"? Basically some of the same stuff you can see in event viewer. Ideally I'd like to be able to have this setup so that once a day it emails me with the daily usage for when a supervisor asks about if their person is actually working (or at least online sending and receiving x amount of data), I'll have some metrics to give them. I realize that actual work output is relevant and more of a managerial issue, but I would like to be able to offer as much as I can from my end when asked. Thoughts? Thanks!

  • DRBD stacked resources: recovering from failure

    - by Marcus Downing
    We're running a stacked four-node DRBD setup like this: A --> B | | v v C D This means three DRBD resources running across these four servers. Servers A and B are Xen hosts running VMs, while servers C and D are for backups. A is in the same datacentre as C. From server A to server C, in the first datacentre, using protocol B From server B to server D, in the second datacentre, using protocol B From server A to server B, different datacentres, stacked resource using protocol A First question: booting a stacked resource We haven't got any vital data running on this setup yet - we're still making sure it works first. This means simulating power cuts, network outages etc and seeing what steps we need to recover. When we pull the power out of server A, both resources go down; it attempts to bring them back up at next boot. However, it only succeeds at bringing up the lower-level resource, A-C. The stacked resource A-B doesn't even try to connect, presumably because it can't find the device until it's a connected primary on the lower level. So if anything goes wrong we need to manually log in and bring that resource up, then start the virtual machine on top of it. Second question: setting the primary of a stacked resource Our lower-level resources are configured so that the right one is considered primary: resource test-AC { on A { ... } on C { ... } startup { become-primary-on A; } } But I don't see any way to do the same with a stacked resource, as the following isn't a valid config: resource test-AB { stacked-on-top-of test-AC { ... } stacked-on-top-of test-BD { ... } startup { become-primary-on test-AC; } } This too means that recovering from a failure requires manual intervention. Is there no way to set the automatic primary for a stacked resource?

  • Ubuntu 12.10 64bit host reboots when trying to install any guest system using VirtualBox

    - by gts123
    I am having a really nasty problem with VirtualBox as everytime I try to install any guest OS(using ISO file as CD for installation media), the installation starts normally but as soon as it is about to start either installing to virtual hard drive or loading(e.g. as LiveFS) it causes the host system to reboot abruptly. Config is as below: Host system: Ubuntu 12.10 64bit - Intel® Core i7-2640M CPU @ 2.80GHz × 4 Virtualbox version: 4.1.18_Ubuntu r78361 Guest OS systems tried: 32bit version of FreeBSD 9, Debian 6, Tails 0.14 VM setup Tried to have the minimal setup necessary just in case it would avoid for each system to make sure I'd avoid conflicts, but to no avail. I've tried different values and combinations of the below but the problem still persists: Shared Clipboard: Disabled Show in fullscreen/seamless: Disabled Remember runtime changes: DIsabled Base Memory: 2048 MB Chipset: PIIX3 IO APIC: Disabled EFI: Disabled Absolute Pointing device: Disabled Processor(s): 1 CPU PAE/NX: Disabled VT-x/AMD-V: Disabled Video Memory: 12 MB 3d/2d acceleration: Disabled Storage IDE COntroller: PIIX3 (same as chipset instead of PIIX4) Use host I/O cache: No Audio: disabled Network adapter: NAT USB controller: disabled No shared folder Also another sideeffect of the reboot is that it appears that it does not log any information in the error log files; not making things any easier. Please help.

  • Installing Ubuntu guest crashes Hyper-V host

    - by Grant
    I have a weird problem that I don't even know where to begin diagnosing. Trying to install Ubuntu to a VM locks up the host system! My setup is: Dell R715 server, dual 16 core AMD opteron processors, 96GB RAM Dell MD3600f SAN Server 2008 R2 Datacenter System Center VMM 2012 There are 5 windows virtual machines running that have had no problems. This is the first linux VM I've tried to create. I setup a VM through virtual machine manager, set the CD drive to a Ubuntu 12.04 server x64 iso, and started it up. It boots up the normal ubuntu install menu, but the second I hit enter on "Install Ubuntu Server", I get disconnected. The HOST machine stops responding to pings. So do all virtual machines on it. It locks up entirely - keyboard on the host won't work, mouse won't move, numlock light won't change. There's no blue screen - the host is sitting at the login screen completely unresponsive. I can't find any relevant logs in event viewer after rebooting. What could cause the host machine to freeze like that? It's not a one time occurrence - it happens every time at the exact same point. Thank god this server isn't in production yet!

  • Cannot send email to info@ or support@

    - by user3022598
    I am trying to send email from my gmail account to a couple user accounts I have on my new Centos server. The email is setup correctly and I can send receive from accounts ok except info and support. I tried to setup two users "info" and "support" I have a php form that sends out email that works fine for all users except info and support. To test this and make sure that something did not change from yesterday i just created a new user "frank" and tried the submit form and it worked fine. From my gmail account i can email "frank" however i cannot email "info" or "support" The logs I pulled are as follows and i think i see the issue but no idea how to fix it. Aug 15 12:20:55 mail postfix/qmgr[1568]: 1815C20A83: from=, size=1815, nrcpt=1 (queue active) Aug 15 12:20:55 mail postfix/local[2270]: 1815C20A83: to=, relay=local, delay=0.28, delays=0.26/0.01/0/0.01, dsn=2.0.0, status=sent (delivered to maildir) Aug 15 12:17:13 mail postfix/qmgr[1568]: 3C18520A7F: from=, size=1818, nrcpt=1 (queue active) Aug 15 12:17:13 mail postfix/local[2201]: 3C18520A7F: to=, orig_to=, relay=local, delay=0.28, delays=0.25/0.01/0/0.01, dsn=2.0.0, status=sent (delivered to maildir) Aug 15 12:15:24 mail postfix/qmgr[1568]: 2F79420A79: from=, size=1813, nrcpt=1 (queue active) Aug 15 12:15:24 mail postfix/local[2155]: 2F79420A79: to=, orig_to=, relay=local, delay=0.29, delays=0.27/0.01/0/0.01, dsn=2.0.0, status=sent (delivered to maildir) For some reason frank goes out fine, however support and info go to root? Why?

  • Apache: How to enable Directory Index browsing at the Doc Root level?

    - by Brian Lacy
    I have several web development projects running on Fedora 13. I generally setup Apache to serve my larger projects as Virtual Hosts, but I've got several small projects cycling through that I don't really care to setup a VirtualHost for each one. Instead I'd like them all under a subdirectory of the main VirtualHost entry. I just want Apache to serve me the directory index when I browse to the host name. For example, the hostname projects.mydomain.com refers to /var/www/projects, and that directory contains only subdirectories (no index file). Unfortunately when I browse to the host directly I get: Forbidden You don't have permission to access / on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. But my virtual host entry in my apache config looks like this: <VirtualHost *> ServerName projects.mydomain.com DocumentRoot /var/www/projects <Directory "/var/www/projects"> Options +FollowSymlinks +Indexes AllowOverride all </Directory> </VirtualHost> What am I missing here?

  • OpenVPN-based VPN server on same system it's "protecting": feasible?

    - by Johnny Utahh
    Scenario: hosted machine (typically a VPS) serving wiki, svn, git, forums, email lists (eg: GNU mailman), Bugzilla (etc) privately to < 20 people. People not on team not allowed access. Seeking VPN-restricted access to said server. Have good user experience with OpenVPN-based servers/clients, but have yet to server-admin such systems. Otherwise, experienced Linux sysadmin. Target system: Ubuntu, probably 12.04. Seeking to put an OpenVPN process on above server to "protect" all the above-mentioned services, enabling only OpenVPN-authorized clients/processes to access above services. (Can easily acquire additional IP address(es) as needed for this setup.) Option: if absolutely needed, can employ an additional, dedicated, "VPN server" VPS simply to be my VPN server "front end." But prefer to have all server processes (VPN server plus other server apps) all running on same machine, if possible. Will consider further if dedicated-VPN-machine setup enables 1. easier installation/administration, 2. better/easier end-user experience, and/or 3. makes system significantly more secure. Any of above feasible? The main intention: create a VPN from purely-hosted resources, and not spend all the effort to make a non-VPN, secure site--which typically means "SSL wrapping" + all the continual webserver-application-update management. Let the VPN server deal with access security, and spend list time pushing said security "down" in the other apps/Apache.

  • Regarding partitions for dual-booting Ubuntu with pre-existing Windows 7

    - by Shasteriskt
    I have zero actual experience with configuring disk partitions and the stuff I have read for the past few hours have been confusing me a bit, so please bear with me. First of all, I'd like to explain what I'm setting to achieve: Windows 7 with: C:\ Windows 7 (pre-existing installation) D:\ Data (Already exists and has files already) Ubuntu 11 - Does not exist yet, but I already have a LiveCD in hand. \root directory for Ubuntu \home on its own partition I plan \swap on its own partition with around 8GB Here is the current situation: I have a single 500 GB hard-disk with Windows 7 x64 installed, and the current partition schemes is as follows: System Reserved: 100 MB (Primary, Active) C: 100 GB - Where Windows 7 is installed (Primary) D: 365 GB - Where my files are located, LOTS of free space (Primary) Now, I would like to shrink my D: drive and create around 40 GB of unallocated disk space for the Ubuntu installation, but here what's confusing me a bit: I'm thinking I would create an extended partition and subdivide it into 3 logical partitions for the Ubuntu setup I had in mind. (If you think my setup is a bad idea, please let me know & why. I also hope you can suggest a better one...) I am aware that I can only have up to 4 primary partitions, or 3 primary partitions with 1 extended parition max. Now, does the System Recovery portion count as one primary partition? I'm really new to these things and it is totally unclear to me. In shrinking my D: drive using Windows 7's Disk Management tool, I would get an unallocated free space which I don't know how to make an extended partition from. It seems like I can only create a primary partition from it, not an extended one. How do I go about it? (I'd also like to note, if it is of any importance, that I am trying to avoid using the option to install Ubuntu alongside Windows, and much rather prefer using the custom install where I can specify which drives I wish to use and stuff. Somehow I feel its safer that way.)

  • Trouble connecting to a local SQL server instance from the web

    - by dfarney
    We have a small network behind a firewall (WatchGuard XTM 2 series) and network switch. On our network we have multiple instances of SQL server, but 1 in specific that I would like to be able to access remotely from our website. We have a static IP address from our ISP and then all the machines on the network have a locally assigned dynamic IP address. When trying to connect to the database from outside our network how do I get the request to be directed to the proper machine / SQL instance? Is it a parameter in my connection string or something in my firewall? A few things to rule out: 1) The firewall is allowing access from the website to our network. I added the site's IP and opened up port 1433. Also, when trying to connect and monitoring the firewall no exceptions come up as they did before I added the proper IP address. 2) Remote connections on the SQL server has been setup and enabled. I've done a lot of reading up on remote connections and I am sure it has been setup properly. I am currently getting this error message on my site: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

  • Dell Vostro Desktop error

    - by goldenmean
    Faced a strange situation at work today. We have people sitting at a table on opposite sides, with power cables underneath the table. This morning when the person sitting opposite to me banged his feet on ground, it disturbed the power cable to my PC and it turned-off. So when I turned it on, it says, "No boot device found" Press F1 to setup or F5 to perform test... There was no physical impact/crash/fall of the desktop cabinet, which could have crashed/damaged the hard disk physically. EDIT: The OS is Windows 7 So I tried to recognize it in the Bios setup, but even there it could not find the SATA disk that is connected to this machine. So then I opened the cabinet, removed the power supply and plugged it back again. Tried to reboot, same error, "Boot device not found" It is not recognizing the hard disk. Any ideas about what might be wrong? Hard-disk crash, OS Crash(But it doesn't even go to the point of loading the disk after the initial Bios execution, so doubt this...) Any pointers about how I should proceed to troubleshoot/solve this error are welcome.

  • DVI splitter not working as expected/confusion between DVI-D and -I

    - by Freakishly
    Hey guys, thanks for looking. I have an ATI FirePro™ V3700 in my desktop machine, and I have been running a dual-monitor setup quite effortlessly, thanks to the two DVI ports on the card. I came upon a third monitor, and wanted to extend my desktop to 3 screens, so I purchased a DVI splitter from Amazon. Now, I can only duplicate the second monitor onto the third, not extend it. I've tried all possible combinations of input to no avail. Here's the setup: The ATI FirePro™ V3700 has two Dual-Link DVI-I outputs The splitter splits a single Dual-Link DVI-I port into two Dual-Link DVI-I outputs Two of the monitors are NEC E222W, and the third monitor is a Dell 2001FP. Each monitor has one D-Sub and one Dual-Link DVI-D input. Cables going from the video card to the monitors are two Dual-Link DVI-D to the NECs and one Single-Link DVI-D to the Dell. Is the problem likely with the DVI-D/DVI-I mismatch? Or is it with the cable on the Dell that is only a Single-Link? The cables are easily replaceable, the monitors not so much. Thanks for your time, I really appreciate it. http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v3700/Pages/v3700-specs.aspx http://www.amazon.com/Cables-Unlimited-DVI-D-Splitter-PCM-2260/product-reviews/B000H09RFM/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 www dot newegg dot com/Product/Product.aspx?Item=N82E16824002495 accessories dot us dot dell dot com/sna/PopupProductDetail.aspx?cs=19&l=en&c=us&sku=320-1578 Apologies for the fudged links, I'm new here and they won't let me post more than two :P

  • A router that supports connecting with 2 different wifi networks

    - by Allan Deamon
    I Have the following setup in one place: We have a small local ISP through wireless. I have a external parabolic antenna, connected to a external usb wifi radio, connected through USB to a desktop old PC. The pc connects do the ISP wiki network, then do a Dial Up (PPPoE) connection through the this wifi setup. This will expand with others mobiles devices to be used. When I need, I take my home wireless router and connect though Ethernet in the PC, which is shares the internet. The problem is that the PC must be always ON and working. I would like to buy a wireless router which could be an AP to the mobile devices, notebooks, etc, as also could connect to the ISP Wifi/PPPoE network. So, this device must: Have one radio with detachable antenna to connect to the external antenna. It must connect as client to a network and then dial up the PPP Have another radio serving as AP (infrastructure) to the local place This can't be very expensive. I found a candidate: ( http://www.tp-link.com/en/products/details/?categoryid=1682&model=TL-WR2543ND ) It have 3 deatachable antennas, working with dual band. Officially, his firmware doesn't support it. My supposition: If internally there is 3 or 2 distinct wlan ports (like wlan0, wlan1), and there is support, i could use a OpenWRT, DD-WRT or Tomato to make this works. It also have 1 USB port, which I cold use to connect my actual USB Wifi card on it instead to the old PC. Another alternative, is a router that can do this out of box, with the original firmware. But I don't think this is a easy thing to find.

  • SFTP, SCP, Secure Webdav: which is the most suitable ?

    - by Xavier Maillard
    Hi, currently, I am hosting a webdav share setup in order to store files I need anywhere I am. It is available via HTTPS. Things are that I do not need all the HTTP machinery -i.e. my nginx http server is only there for this webdav folder. I am not sure I made the best choice. My requirements on the client side are: secured transfers mountable as a network drive at work with 'near realtime sync' usable for any OS I could use (including my mobile (android)) At first, I chose webdav since it would pass through my work proxy (which refuses all that is not on HTTP/S (port 80 or 443)). Today, I am not satisfied with the setup and even if nginx memory footprint is pretty small, its webdav support is not really "clean" and full. What would you recommend between SFTP, SCP and the current webdav solution ? I think SFTP is the closest solution but I still have to find out how to pass through my proxy ;) SCP seems quite limited as I read about it (only file transfers if I read right). Cheers

  • Inbox not updating in Exchange 2010, all users affected

    - by TuxMeister
    I'm battling against this darn issue this morning. We have the following setup: Big Hyper-V machine hosting the servers as VM's VM for CAS: WEB.XXX.local VM for Mailbox: EXC.XXX.local Servers are running Server 2008 R2 with Exchange 2010 SP1 Clients are all running Windows 7 Pro x64 with Outlook 2010 x64 The problem we're having is that nobody is able to see any emails received today (16th of October), but they are able to send externally. When I reply back to the email received externally, I don't get an NDR, yet the user cannot see my email. This is what I found and tried thus far: If we create a subfolder in Outlook 2010 and move any email from the inbox into that folder, changes will be immediately reflected in OWA We've been sending test emails to other users internaly and external email addresses and the sent items folder contains all those tests, synced properly to OWA as well Have tried crating a new profile, new emails are still missing Tried disabling Cache Mode, still no luck Also disabled "Download shared folders", still no luck Tried to setup a brand new Exchange mailbox and configured it on a VM that never had Outlook on it, still the same issue Tried restarting Exchange services on both CAS and Mailbox servers, no luck Tried rebooting both CAS and Mailbox servers, still no luck Performed a Mailbox Discovery on my admin account, emails from today are being found in the Discovery results, so the stuff is there, just not updating the user inboxes Any idea about what this hellish thing can be? I've done everything I can think of and also everything I could find out there. Let me know if you need any more details and thanks for reading this!

  • How can I make IPv6 on OpenVPN work using a tap device?

    - by Lekensteyn
    I've managed to setup OpenVPN for full IPv4 connectivity using tap0. Now I want to do the same for IPv6. Addresses and network setup (note that my real prefix is replaced by 2001:db8): 2001:db8::100:0:0/96 my assigned IPv6 range 2001:db8::100:abc:0/112 OpenVPN IPv6 range 2001:db8::100:abc:1 tap0 server side (set as gateway on client) 2001:db8::100:abc:2 tap0 client side 2001:db8::1:2:3:4 gateway for server Home laptop (tap0: 2001:db8::100:abc:2/112 gateway 2001:db8::100:abc:1/112) | | | (running Kubuntu 10.10; OpenVPN 2.1.0-3ubuntu1) | wifi | | router | | OpenVPN INTERNET | eth0 | /tap0 VPS (eth0:2001:db8::1:2:3:4/64 gateway 2001:db8::1) (tap0: 2001:db8::100:abc:1/112) (running Debian 6; OpenVPN 2.1.3-2) The server has both native IPv4 and IPv6 connectivity, the client has only IPv4. I can ping6 to and from my server over OpenVPN, but not to other machines (for example, ipv6.google.com). Using tcpdump on both the server and client, I can see that packets are actually transferred over tap0 to eth0. The router (2001:db8::1) send a neighbor solicitation for the client (2001:db8::100:abc:2) to eth0 after it receives the ICMP6 echo-request. The server does not respond to that solicitation, which causes the ICMP6 echo-request not be routed to the destination. How can I make this IPv6 connection work?

  • Migrating WebLogic 10.3.0 to new host. Slow managed server startup times

    - by wadevondoom
    We are migrating our Blue Martini Commerce application (only supported on WebLogic 10.3.0) to a new host (Redhat 6.3 on a VMWare ESX vm). We are seeing extremely slow start up times for our managed server(s) that is basically 20x slower than our current production. As a for instance the Publish managed server takes ~30 - 45 seconds in current production and in the new environment it takes ~10 minutes. The setup uses the same domain structure and JVM as the current production environment. The same setup files are used. We use jdk1.6.0_33 on 64 bit architecture. We used the generic 64bit weblogic installer and used pack / unpack utilities to migrate the domain. The JAVA_OPTS to start this server are: "-d64 -Xms256m -Xmx512m -XX:PermSize=48m -XX:MaxPermSize=256m" The sysadmins have checked /etc/sysctl.conf and /etc/limits.conf to ensure we were not hitting some kind of process limit. As I am not sure what this managed server does from a Blue Martini perspective during the phase of startup I also had the DBA check to ensure that Oracle RAC (11.2.0.3) wasn't also hitting some kind of process limit or if there was a tns listener issue. The new host is quite a bit stricter with their server lock downs so there are a few differences.... Redhat 6.3 in new env, RH 5.7 in current SElinux is targeted in new env and disabled in current VM in new env and dedicated hardware in current iptables disabled in current. It was enabled in new prod but I had them disable it just in case I apologize for not being more specific. I am mostly hoping got some tips. I do not have the typical root access I would normally have in this environment. I am just hoping got a path forward. I did a few 'kill -3' to see if there are blocked threads and I got nadda. The service works for all intents and purposes it is just painfully slow. Thanks you all in advance for reading and best regards. Wade

  • How to connect the virtual networks of vmware guests running on different hosts?

    - by gyrolf
    In a test setup, we are running several virtual machines on a single vmware workstation host. All virtual machines are connected via a "host only" network. This runs fine up to 2 or 3 virtual machines (depending on the host hardware). To allow more virtual machines, we want to use more host machines. Details about the environment and applications: Host PCs are running Windows XP in a corporate intranet. VMware used is Workstation 6.5 Guests are running Windows Server 2003 All guests act as Web Servers One of the guests additionally acts as Windows File server, offering shared folders for the other guests to connect to. Restrictions: VMware guests shall not be visible from the intranet. Changes to the host PC are restricted by corporate policy. In the virtual network, no domain controller exists. All virtual machines are member of the same workgroup. Running the virtual network as NAT is possible. Port forwarding might be used if it does not conflict with ports used by the host PC. Looking for a solution, I found hints about using router or vpn software on the hosts, but without any details how to setup. (I found a similar question Sharing the network between 2 VMware hosts, but the answer was not sufficient for me.)

  • VPN into multiple LAN Subnets

    - by Rain
    I need to figure out a way to allow access to two LAN subnets on a SonicWall NSA 220 through the built-in SonicWall GlobalVPN server. I've Googled and tried everything I can think of, but nothing has worked. The SonicWall NSA management web interface is also very unorganized; I'm probably missing something simple/obvious. There are two networks, called Network A and Network B for simplicity, with two different subnets. A SonicWall NSA 220 is the router/firewall/DHCP Server for Network A, which is plugged into the X2 port. Some other router is the router/firewall/DHCP server for Network B. Both of these networks need to be managed through a VPN connection. I setup the X3 interface on the SonicWall to have a static IP in the Network B subnet and plugged it in. Network A and Network B should not be able to access each other, which appears the be the default configuration. I then configured and enabled VPN. The SonicWall currently has the X1 interface setup with a subnet of 192.168.1.0/24 with a DHCP Server enabled, although it is not plugged in. When I VPN into the SonicWall, I get an IP address supplied by the DHCP Server on the X1 interface and I can access Network A remotely although I do not have access to Network B. How can I allow access to both Network A and Network B to VPN clients although keep devices on Network B from accessing Network A and vice-versa. Is there some way to create a VPN-only subnet (something like 10.100.0.0/24) on the SonicWall that can access Network A and Network B without changing the current network configuration or allowing devices on both netorks "see" each other? How would I go about setting this up? Diagram of the network: (Hopefully this kind of helps) WAN1 WAN2 | | [ SonicWall NSA 220 ]-(X3)-----------------[ Router 2 ] | | (X2) 192.168.2.0/24 10.1.1.0/24 Any help would be greatly appriciated!

  • hyper-v cluster behavior when losing network connectivity

    - by ChristopheD
    Setup: (rather new) Hyper-V R2 cluster with 2 nodes (in failover configuration). Fysical host OS: Windows Server 2008. About eight VM's (mixed: Windows Server 2008 and Linux) Yesterday we had a power outage of about 15 minutes. Our blades are on UPS so the fysical host machines (Windows Server 2008) never went down. Our main switches are not on UPS (yet) and we saw the behaviour similar to the following (as distilled from the event logs). The nodes in the cluster lost means of communication (because the external switches went down). The cluster wants to bring down one (the first) of the nodes (to start failover?). The previous step impacts clustered storage where the virtual machine VHD's are located. All VM's got brutally terminated and were found in a failed state in the failover manager in the host OS'es. The Linux VM's were kernel panicking and looked like they had their disk ripped out. This whole setup is rather new to us, so we are still learning about this. The question: We are putting switches on UPS soon but were wondering if the above is expected behavior (seems rather fragile) or if there are obvious improvements configuration-wise to handle such scenario's ? I can upload an evtx file concerning what exactly was going on in case that's necessary.

  • Wifi Works with Android and Windows 8 but not Linux and Win 7

    - by eramm
    Support has told me that our company wide wifi network is setup to support mobile phones only. However it doesn't make sense to me that they can identify a mobile device rather they have setup the Access Point to use a protocol that is only supported on Android and Windows phones. Because the Access Point supports Windows mobile this means that laptops running Windows 8 can also connect to the Access Point (proven). So it stands to reason that since Android is based on Linux there must be a way to connect using Linux as well. iwlist shows IEEE 802.11i/WPA2 Version 1 Group Cipher : TKIP Pairwise Ciphers (2) : TKIP CCMP Authentication Suites (1) : 802.1x WIreshark seems to show that a connection is being made to a website to get a certificate and use a Domain Controller for authentication. Questions: 1) what protocol could they be using that is supported on Win Mobile and Android but not on Win 7 and Linux (Debian) ? 2) what tools can I use to help me discover what protocol i need to support ? I have used iwlist and wireshark but I was not able to glean to much useful information from them. I can post the results if needed. 3) is there an app i can use on my Android phone to help me understand what kind of network it is connecting to ? I can provide more information if you tell me how to get it. I just don't know what I am looking for.

  • Recovering ZFS pool with errors on import.

    - by Sqeaky
    I have a machine that had some trouble with some bad RAM. After I diagnosed it and removed the offending stick of RAM, The ZFS pool in the machine was trying to access drives by using incorrect device names. I simply exported the pool and re-imported it to correct this. However I am now getting this error. The pool Storage no longer automatically mounts sqeaky@sqeaky-media-server:/$ sudo zpool status no pools available A regular import says its corrupt sqeaky@sqeaky-media-server:/$ sudo zpool import pool: Storage id: 13247750448079582452 state: UNAVAIL status: The pool is formatted using an older on-disk version. action: The pool cannot be imported due to damaged devices or data. config: Storage UNAVAIL insufficient replicas raidz1 UNAVAIL corrupted data 805066522130738790 ONLINE sdd3 ONLINE sda3 ONLINE sdc ONLINE A specific import says the vdev configuration is invalid sqeaky@sqeaky-media-server:/$ sudo zpool import Storage cannot import 'Storage': invalid vdev configuration I should have 4 devices in my ZFS pool: /dev/sda3 /dev/sdd3 /dev/sdc /dev/sdb I have no clue what 805066522130738790 is but I plan on investigating further. I am also trying to figure out how to use zdb to get more information about what the pool thinks is going on. For reference This was setup this way, because at the time this machine/pool was setup it needed certain Linux features and booting from ZFS wasn't yet supported in Linux. The partitions sda1 and sdd1 are in a raid 1 for the operating system and sdd2 and sda2 are in a raid1 for the swap. Any clue on how to recover this ZFS pool?

  • SBS 2008 R2: Did something change with anonymous relays?

    - by gravyface
    Have noticed that prior documentation on setting up anonymous relays in SBS 2008 no longer work without some additional configuration. Used to be able to follow this documentation, which is basically: setup a new receive connector add the IP address(es) that will be permitted to relay check off "anonymous" under Permission Group and then run the Exchange shell script to grant permissions. Now what seems to be happening is that if the permitted IP address happens to fall within the same address space as another more restrictive Receive Connector (like the "Default SBS08" one) and possibly if it's ahead of the new Receive Connector alphabetically (haven't tested that yet), the relay attempt fails with "Client Was Not Authenticated" error. To get it to work, I had to modify the scope of the "Default SBS08" Receive Connector to exclude the one LAN IP that I wanted to allow relaying for. I can't recall ever having to do this for Exchange 2007 Standard and/or any other SBS 2008 servers I've setup over the last couple of years and I don't remember doing this and the wiki entry I added at the office doesn't mention it either. So my question is, has anyone else experienced this? Has there been a new change with R2 or perhaps an Exchange Service Pack?

  • Why is windows not able to create a system partition?

    - by hughes
    I'm reinstalling Windows 7 64 bit, and I encountered an issue I've never seen before. I have a legit copy of Win 64 Professional, and I've installed it probably a half dozen times on this machine in the past without a problem. Googling the error only brings me to issues with people who are upgrading to win7. The drive itself seems to not have a problem. I can mount it on other systems and I can create an NTFS partition on it on other machines. I can install Ubuntu on it without any issues. Additionally, if I try using my alternate backup hard drive, the installer gives the same error. I have run diskpart from the setup page and clean seems to report that all is well. However, I cannot get past the screen below, which says Setup was unable to create a new system partition or locate an existing system partition. This happens regardless of whether or not the disk space is already allocated. What is causing this? How do I solve or get past this?
