• Routing and Remote access rule not being applied internally (Windows SBS)

  - by Tim Saunders

  Hi, I have a Microsoft Small Business Server. I have pointed an external domain name to the external fixed IP address for the server. In routing and remote access I have defined a service for our subversion server as follows: Incoming port: 8443 Private address: 192.168.10.5 Outgoing port: 8443 192.168.10.5 is our development server, not the SBS (which is at 192.168.10.1) This rule works correctly if I am not on our internal network. However if I am on the internal network this rule does not get applied. What can I do/set so this rule is applied both internally and externally (so users with laptops et, don't keep having to change the URL by which they access the subversion server) Not sure what other info you may need, so please let me know if more details are required.

• Lost contact with my NAS after changing its IP

  - by Beles

  I did some brain-dead reconfiguring of my D-Link DNS-323 NAS some days ago. I have a home network where each computer gets a dynamically allocated IP address starting at 192.168.1.100. The irritating point (for me at least) was that the NAS changed IP if the power went down or I turned off the router. I then had to remap a drive-letter to point to the new IP address of the NAS. To remedy that I configured the NAS to have a static IP, 192.168.0.10. I had no good reason to choose that IP, other than I found it in a user manual for the NAS. After I changed the IP and rebooted the NAS it disappeared from the network and was never to be found again. Now I have a black brick standing in my home, looking good, but "dead". Could anyone point me in a direction which helps me solve this problem? I have about 100gb worth of pic of my children on this brick so I really want it back :-) Sincerely,

• .NET and SMTP Configuration

  - by koevoeter

  Sometimes I feel stupid about discovering .NET features that have been there since an old release (2.0 in this case)... Apparently you can just use this configSecion “mailSettings” and never have to configure your SmtpClient instance in code again (no, not hard-coded): <system.net>     <mailSettings>         <smtp deliveryMethod="Network" from="My Display Name &lt;[email protected]&gt;">             <network host="mail.server.com" />         </smtp>     </mailSettings> </system.net> Now you can go all like: new SmtpClient().Send(mailMessage); …and everything is configured for you, even the from address (which you can obviously override).

• Cannot Mount USB 3.0 Hard Disk ?!!

  Hi, I have a USB 3.0 external hard disk which I am unable to mount. The entry appears in the "lsusb" command, but I do not exactly understand how to mount it.

• How to cache streaming video and silverlight with squid windows reverse proxy

  - by V. Romanov

  We have an intranet web server running a silverlight application (ACTUS media monitor if anyone cares to know). The server is used to record video and stream it to clients through a CDN solution. We want to put a reverse proxy in between the server and CDN provider in order to remove the office network bottleneck that's currently strangling us. I've set up SQUID for windows on a separate machine outside the network using squid BasicAccelerator configuration setting. It seems to work as far as the reverse proxy is concerned, requests are forwarded and the application is working but it doesn't seem to cache anything (no space is used on the drive where squid is installed). I found to explicit setting to turn caching on in squid, so i assume it's on by default. Perhaps I need some other trick to make the video and/or silverlight cacheable? Any help will be appreciated. Any info you need to help me will be provided at once. Thanks in advance!

• Make puppet agent restart itself

  - by SamKrieg

  I've got a file that notifies the puppet agent. In the network module, the proxy settings are included in the .gemrc file like this: file { "/root/.gemrc": content => "http_proxy: $http_proxy\n", notify => Service['puppet'], } The problem is that puppet stops and does not restart. Aug 31 12:05:13 snch7log01 puppet-agent[1117]: (/Stage[main]/Network/File[/root/.gemrc]/content) content changed '{md5}2b00042f7481c7b056c4b410d28f33cf' to '{md5}60b725f10c9c85c70d97880dfe8191b3' Aug 31 12:05:13 snch7log01 puppet-agent[1117]: Caught TERM; calling stop I assume the code does something like /etc/init.d/puppet stop && /etc/init.d/puppet start Since puppet is not running, it cannot start itself... it kind of makes sense. How to make puppet restart itself when this file changes? Note that this file may not exist as well.

• What is Finder doing when it has a spinner in the bottom-right?

  - by rspeicher

  Whenever I open a folder on a remote network share that hasn't been opened since I last booted, Finder displays this animated spinner in the bottom-right (see picture below) for about 30 seconds and won't display any of the folder's contents until it's done doing whatever it's doing. This makes browsing the share painfully slow for seemingly no reason. Why's it doing this? I should note that I've disabled .DS_Store files littering network shares using defaults write com.apple.desktopservices DSDontWriteNetworkStores true, so maybe that's why. I'm kind of hoping it's something else, though.

• Airport Express chokes Wi-Fi for a few seconds, several times per hour. Any idea why?

  - by user13727

  I'm using a MacBookPro connected to an AiportExpress' Wi-FI network. Every once in a while, the Wi-Fi will choke up and either drop some packets, or lag horribly for several seconds. I'm losing hair over this because every time I chat on Skype, the call hangs randomly due to this problem. Any idea what's wrong? Some more details: two networks are set up: 2.4Ghz and 5Ghz, and the issue happens on both the network uses WPA2 Personal for security the Airport is in the same room with my computer the Airport is fairly new, bought this summer, model number off the back: A1392 tried connecting to a neighbours wifi to see if it's a problem with my computer, or interference. It's not, it doesn't happen on their network. tried resetting it several times tried changing channels manually Ping results are below, so you can see what I'm talking about.

• Server 2012 R2 DNS Conditional forwarding not working reliably, possible caching issue?

  - by Matt

  I have a bit of a home lab setup with a domain controller that is acting as the DNS server for my network. For everything, it's working fine and forwards external DNS requests to my ISP. The household recently wanted to get Netflix going and it seemed a DNS option was better than a VPN to get around the region locking, so I signed up for unblock-us.com Since I have a Windows DNS server I thought I'd be clever and make use of conditional forwarders and added the Netflix domain to the list. Initially this worked well and all devices on the network could now access Netflix, however after about an hour going to the Netflix site would result in a page cannot be found. Doing an nslookup of Netflix.com from my PC resulted in it not returning any IP addresses. As a test, I deleted the Netflix domain from the DNS servers cache and things started working again - devices could get to the site again however the same thing happens again after around half an hour to an hour. Have I missed something here that's causing it to stop working?

• Forwarding wifi traffic to wired pc

  - by brydgesk

  I'm trying to play around with Wireshark on my home network, and was wondering if there is a way to create a new connection on my PC that receives all wifi packets on the network. The PC is a wired Windows 7 machine, and I'm using DD-WRT on an Asus RT-N16 router. I'm not trying to hack anything, I have full admin access to the router itself. My searching has led me to articles about client bridges and repeater bridges, but none of them seemed to apply entirely to my situation. I'd like to continue using my standard wifi connection, but make my PC act as a repeater that receives all wifi traffic. Again, the PC has no wireless connection. I've used tcpdump which is installed on the router itself, but I'd be more comfortable analyzing the packets in Windows, as I'm trying to learn Wireshark. Thanks

• VirtualBox - multiple guests, each with a single bridged adapter?

  - by Martin

  I am running a dedicated server (located at Hetzner, Germany) that runs VirtualBox in order to virtualize several services accross multiple virtual guests. Those guests are supposed to communicate with each other (for instance, a virtual web server has to access a virtual database server); to be reachable from the dedicated server (for instance, SSH access); and to access the Internet via the dedicated server (for instance, to download security updates) Currently, this is achieved by having host-only adapter vboxnet0 on the dedicated server and two virtual interfaces on each guest. There, virtual adapter eth0 is attached to vboxnet0 (to achieve (1) and (2)), virtual adapter eth1 is attached to VirtualBox' NAT (to achieve (3)). Via eth0, the guests have access to a DHCP and a DNS server, both running on the dedicated server (there, bound to vboxnet0). This allows me to assign custom IP addresses and names. Via eth1, VirtualBox pushes a proper route that enables each guest to access the Internet (via eth0 on the dedicated server). This setup with two virtual adapters frequently leads to problems and at leasts complicates many things. For instance, on the dedicated server there is OpenVPN which allows to access the virtual machines via the Internet; futhermore, there is Shorwall that controls the incoming and outgoing network traffic between the Internet, the dedicated server, and the individual virtual machines. Not to mention automatic installation of servers via PXE... Therefore, I would prefer to have only one single virtual adapter on each guest which would be used for both incoming and outgoing connections. As far as I understand, one would basically use a bridged interface for that very purpose. Now the question arises: Which interface on the dedicated server would the bridge use? eth0 on the host server is not an option, as this is prohibited by the provider. A virtual interface eth0:0 would not make any sense, as a bridge always uses a physical interface (eth0 in this case). Would it be possible to create a bridged interface in each virtual machine that would "dangle in the air"? Thus, without a complement on the dedicated server? How would I have to set up the routing on the host server? Please note that the host / dedicated server has only one network adapter (eth0) which is connected to the provider's network. Regards, Martin

• How to get faster graphics in KVM? VNC is painfully slow with Haiku OS guest, Spice won't install and SDL doesn't work

  - by Don Quixote

  I've been coming up to speed on the Haiku operating system, an Open Source clone of BeOS 5 Pro. I'm using an Apple MacBook Pro as my development machine. Apple's BootCamp BIOS does not support more than four partitions on the internal hard drive. While I can set up extended and logical partitions, doing so will prevent any of the installed operating systems from booting. To run Haiku directly on the iron, I boot it off a USB stick. Using external storage is also helpful because I am perpetually out of filesystem space. While VirtualBox is documented to allow access to physical drives, I could not actually get it to work. Also VirtualBox can only use one of the host CPU's cores. While VB guests can be configured for more than one CPU, they are only emulated. A full build of the Haiku OS takes 4.5 under VB. I had the hope of reducing build times by using KVM instead, but it's not working nearly as well as VirtualBox did. The Linux Kernel Virtual Machine is broken in all manner of fundamental ways as seen from Haiku. But I'm a coder; maybe I could contribute to fixing some of those problems. The first problem I've got is that Haiku's video in virt-manager is quite painfully slow. When I drag Haiku windows around the desktop, they lag quite far behind where my mouse is. It's quite difficult to move a window to a precise position on the screen. Just imagine that the mouse was connected to the window title bar with a really stretchy spring. Also Haiku's mouse lags quite far behind where I have moved it. I found lots of Personal Package Archives that enable Spice from QEMU / KVM at the Ubuntu Personal Package Arhives. I tried a few of the PPAs but none of them worked; with one of them, the command "add-apt-repository" crashed with a traceback. There is a Wiki page about Spice, but it says that it only works on 64-bit. My Early 2006 MacBook Pro is 32-bit. Its Apple Model Identifier is MacBookPro1,1; these use Core Duos NOT Core 2 Duos. I don't mind building a source deb for 32-bit if I can expect it to work. Is there some reason that Spice should be 64-bit only? Does it need features of the x86_64 Instruction Set Architecture that x86 does not have? When I try using SDL from virt-manager, the configuration for Local SDL Window says "Xauth: /home/mike/.Xauthority". When I try to start my guest, virt-manager emits an error. When I Googled the error message, the usual solution was to make ~/.Xauthority readible. However, .Xauthorty does not exist in my home directory. Instead I have a $XAUTHORITY environment variable. There is no way to configure SDL in virt-manager to use $XAUTHORITY instead of ~/.Xauthority. Neither does it work to copy the value of $XAUTHORITY into the file. I am ready to scream, because I've been five fscking days trying to make KVM work for Haiku development. There is a whole lot more that is broken than the slow video. All I really want to do for now is speed up my full builds of Haiku by using "jam -j2" to use both cores in my CPU. I may try Xen next, but the last time I monkeyed with Xen it was far, far more broken than I am finding KVM to be. Just for now, I would be satisfied if there were some way to use my USB stick as a drive in VirtualBox. VB does allow me to configure /dev/sdb as a drive, but it always causes a fatal error when I try to launch the guest. Thank You For Any Advice You Can Give Me. -

• LinkSys WRT54GL + AM200 in half-bridge mode - Setup guide recommendations?

  - by Peter Mounce

  I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. My ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

• Windows Server 2008: Terminal Services / VDI

  - by JohnyD

  I have a Dell R710 with 72GB of memory running Hyper-V. Within Hyper-V I have a Windows 2008 (32-bit) VM running Terminal Services. How do I allocate memory so that any user who connects to this Terminal Server (from their thin-client) is allocated 2GB (or whatever amount I choose) of memory? Currently I have provisioned the TS with 2GB of memory but it seems that this is shared among all that connect. Please let me know if there is further information I can provide. Thank you. Update 1: What I'm looking to accomplish with this server is setting up a VDI to allow users to connect from thin-clients from within our network. They will also have to connect from outside our network via VPN which is already in place. Am I able to set this up using Windows Server 2008 (not R2) because I have a 16-bit application which needs to be supported. Unfortunately it's not a candidate as a Remote App.

• FTP Access Denied when uploading to server

  - by Albert

  Ok, here's the story. I have a server running FTP 'out there' I can connect to it using the admin account, browse files, download files. When I try to upload files, I get 550 Access Denied. I have tried through FileZilla and command line. I have windows firewall turned off (on my machine) I can UPLOAD files from another machine (using the same admin account) on our local network (that means, same public IP) what is the problem? I am running Windows 7, Build 7100 and the other machine on the network is running XP SP3 The thing that gets me though, is that this worked for the last probably 4 months, without a problem, I get back in the office after a weekend today and it won't work...

• Cannot schedule task to run under domain user account other than current user

  - by Filburt

  On our Win 2008 machines I can't schedule tasks for domain users because the domain name does not resolve to network name but the AD dc name. The "network name" looks like ABCDEFGE-HIJKLM and the "dc" / "name" would look like ABCDEFGE-HIJKLMN. When selecting the domain user account the account qualifier will look like ABCDEFGE-HIJKLMN\task.user. This results in an "invalid account" error. When however keeping the currently logged in user it will display ABCDEFGE-HIJKLM\current.user. Does this behaviour result from the presumable "illegal" domain name? Is there a workaround for this? update I could of course log in as the desired domain account and create the task but since this account is a account used for running services I want to avoid creating a user profile on the machine.

• How to setup an iTunes library to use between two Macs?

  - by stead1984

  As you can tell this is no where near work related. I have an iMac G5 where my itunes is currently hosted, I have also just got a new MacBook Pro. What I want to be able to do is sync my itunes library from my iMac to my MacBook Pro, that way it can be accessible away from my home network, then if I make any changes to the itunes library (like change a track name) it will sync these changes back once I connect back to the home network. My current itunes contains music, videos, podcasts, playlists and iPhone apps, I would also like iTunes to track play counts collectively between the iMac and the MacBook Pro.

• Windows 7 stopped connecting to samba share

  - by Jan

  I have a problem with Windows 7 Home connecting to samba on linux server. It's worked fine for a year and without any changes in configuration or updates it suddenly stopped working. The strangest thing for me is that it stopped working for no reason that I could think of. After a few minutes after trying to connect I get: \\ip is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Other computers in that network (XP machines) connect to samba without any problem. I've tried adding LmCompatibilityLevel as described here: http://www.tomshardware.com/forum/75-63-windows-samba-issue , but it didn't help.

• How do I prevent libvirt from adding iptables rules for guest NAT networks?

  - by Jack Douglas

  Similar to this old request on BugZilla for Fedora 8, I'm hoping something has changed since then or someone knows another way. I want to manage the iptables rules by hand—the one-size-fits-all automatic rules don't suit me at all. These rules seem to be added and removed when a network is started and destroyed. Is there a way of either preventing these rules being added at all or hooking a script into the network start that restores the default rules afterwards. For now, I'm using a very crude method with cron, but I hope there is a better way: * * * * * root iptables-restore < /etc/sysconfig/iptables

• Coldfusion server VERY slow page loads

  I inherited a windows server 2003 coldfusion 7 server a few weeks ago. Today a network cable was unplugged by accident from the server. On plugging it back in, pages were NOT loading at all. Rather, we were receiving a generic coldfusion error page. After restarting IIS several times and coldfusion even more than that, we finally got pages to start loading. However, the loading is extremely slow (30+ seconds) on pages that used to load instantly. Loading through the local network (IE localhost/cfide/administrator) does nothing to help the load speed. I am not familiar with IIS or Coldfusion (We're in the process of migrating this to Linux/PHP), so this is all new territory to me. I'm hoping someone may have experienced this issue in the past and can help me solve it. I'm happy to provide any additional information that might be necessary....I'm just not sure what information you might need in order to help. Thanks for your time.

• Can admins monitor my activity locally even when I use a VPN?

  - by Arjun Create

  My school has one of those super overreacting web blockers (specifically Fortisnet) that blocks things that should be accessible by a high-school senior trying to research projects. Despite many students' complaints the administration's hands are tied due to parents' complaints. I have setup a VPN account from http://www.vpnreactor.com. With this I am able to bypass the blocker. I know this service hides my IP from websites and servers on the web. I also know that the school pays an IT guy just to monitor sites and network traffic that the students are using. Basically, will he be able to see my network traffic? More importantly, will he be able to trace it to my computer or its MAC address? I am connecting over Wi-Fi, not ethernet.

• IPv4 private address assignment

  - by helloworld922

  I'm working on a private network which uses static IPv4 addresses as well as DHCP addressing for the physical LAN network. At a previous company I worked at they would assign static addresses in the 10.*.*.* space and all DHCP/LAN addresses were assigned in the 192.168.*.* space. Both of these address spaces are defined in the IPv4 private address space and there were never any internal conflicts. From personal experience at home, school, at work, and pretty much any other machine I've dealt with extensively (Windows and a few Linux distros), the DHCP server would always by default choose an address from the 192.168.*.* address space. Now my question is can I rely on this behavior? Do DHCP servers always by default assign from the 192.168.*.* pool (or any pool other than the 10.*.*.* pool), leaving the 10.*.*.* pool free for private static addressing? If not, under what conditions might a DHCP server choose an address in the 10.*.*.* address space?
