  • Best free WebDAV client for Windows?

    - by Jones
    Related question: http://stackoverflow.com/questions/340567/what-is-the-best-webdav-client-for-windows The pain point for me with Windows Explorer as a WebDAV client (or as an FTP client) is that downloading large amounts of files usually results in Windows calculating transfer times and Explorer freezing. Given that, what is the best free WebDAV client for Windows? I think something like Filezilla, but for WebDAV, would be ideal.

    - by Mohammadreza
    I have recently installed Team Explorer on one of my machines that has Visual Studio 2008 SP1 installed. But know whenever I click a work item or trying to open a team query I get the following error: Could not load type 'Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemTypeDeniedOrNotExistException' from assembly 'Microsoft.TeamFoundation.WorkItemTracking.Client, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' I even repaired the installation of Team Explorer 2008 but it does not solve my problem. Does anybody know how can I get rid of this error? Thanks.

  • Program not connecting to new database

    - by Manoj
    Hi, I moved a VS Solution file from an old PC to a new PC. When I opened the solution in VS2010, I found that the database connections in database explorer was not present. Now I want the project to connect to a SQL Server database which is local to the new PC. I have moved the database files (.ldf and .mdf) to the new location and created new connection in Database explorer. But the program seems to be not fetching any data when I run it. What are the other changes I need to do?

  • Port forwarding on Fortigate 50B

    - by sindre j
    I have serious problems setting up port forwarding on a Fortigate 50B. The unit is basically running as factory default, the wan1 interface is connected to my fibre optic internet modem, and my lan is connected to the internal switch of the Fortigate. The factory default firewall policy allowing traffic from the internal interface to wan1 is kept and I'm able to access the interet as normal. Then I added a virtual ip and a firewall policy for allowing access from the internet to my local servers (ip 192.168.9.51) webserver (standard port 80). The settings I made are as follows. Edit Virtual IP Mapping Name : Server VIP External interface : wan1 Type : Static NAT Extermal IP Address/Range : 0.0.0.0 Mapped IP Address/Range : 192.168.9.51 Port Forwading : not checked Firewall policy Source interface/Zone : wan1 Source address : all Destination interface/Zone : internal Destination address : Server VIP Schedule : always Service : HTTP Action : ACCEPT no other settings checked What happens now is that I'm unable to access internet from my server, I'm not getting through to the webserver from internet either. I'm able to ping a site on the outside, but all web traffic is blocked, both ways. I've checked the documentation, but as far as I can tell I have set this up correctly. Anyone here with knowledge of Fortigate port forwading/NAT?

  • IPtables AWS EC2 NAT/Reverse NAT - For Reverse Proxy style setup but with IPtables

    - by Mark
    I was thinking initially needing to do a reverse proxy or something so I could get some SSL/TLS traffic look like it is being terminated at a server and IP address in the AWS cloud, and then that traffic is forwarded onto our actual web servers that aren't in the cloud... I've not done much iptables pre and post routing before Dnat or Snat which I know are the things I need or a combination of the things I need in order achieve what i'm trying. Things to note:- Client/User - Must not be able to see backend IP address and only see the IP address of the cloud box https (TLS/SSL) - connection shouldn't be terminated at the cloud box, it should act like a router almost EC2 instance - Has only one network interface available to play with... this is thus an (internet <- internet) type of routing going on. EC2 instance IP address is already more or less behind a NAT that I have no control over, for example... Public ip address could be 46.1.1.1 but instance IP will be 10.1.1.1. Connections from client will go to 46.1.1.1 which will end up at the instance and on interface 10.1.1.1. The connection from the client then needs to be forwarded (DNAT) onto the backend web servers which are back out on the internet (SNAT). Possibly a part of the problem could be that the SNAT will need to be set to the external interface of the instance and I wonder if this makes it harder for IPtables to track the connection? So looking to basically, have it look as though connections are terminating at this server and its IP address. Whereas all that's really happening is the https request and connection is being forwarded straight onto another internet facing web server. How possible does that sound?

  • Cisco: Site-to-site VPN with cisco 878 and ASA weirdness

    - by cpf
    I currently have 2 sites, both connected to each other through 2 firewalls / routers in a site-to-site VPN. Pinging from server to server (Using 2mb/2mb SDSL) through that VPN obviously works, however, at one site, we have another internet connection (7m/400k ADSL), and only the link between the two sites should be on the other connection. All pc's should go over the other connection for internet, just communication between servers & Communication between pc's and the server at the other side should go through there too. What is configured at the moment is the server is using the SDSL directly as default gateway. Since it's not intended to surf anything it is a safe config. PC's are configured on the ADSL as default gateway. Now I wanted to route through everything that uses the range used on the other site, it should be sent from the ADSL modem to the SDSL modem, which has the VPN connection. I figured I could use OSPF to do so, however, OSPF doesn't seem to "detect" the range of the external site. Also (due to bad ip subnetting thanks to the other administrator), the ip used internally as the server on the other site also exists on the internet (causing a lot of confusion), so rdp-ing from our server to the server of the other site works (somehow), but tracerouting on the SDSL router (which should actually, in my opinion, go over the VPN) actually goes all over the internet. My question(s): Why doesn't the SDSL router ping the external ip through VPN, but the server does? Why can't I route from the ADSL router to the SDSL over VPN? I would seriously appreciate some help, since I can't figure out why it does it like this.

  • Cisco SR520w FE - WAN Port Stops Working

    - by Mike Hanley
    I have setup a Cisco SR520W and everything appears to be working. After about 1-2 days, it looks like the WAN port stops forwarding traffic to the Internet gateway IP of the device. If I unplug and then plug in the network cable connecting the WAN port of the SR520W to my Comcast Cable Modem, traffic startings flowing again. Also, if I restart the SR520W, the traffic will flow again. Any ideas?

  • How to use connectify to share files between 2 laptops, one running Windows 7?

    - by p2pnode
    I have 2 laptops one running XP and another Windows 7. Both have WiFi-card installed. I want to be able to share files between these 2 machines and then in next step also be able to share internet connection. I have heard that Connectify on Windows 7 is a very handy and easy tool to set up a hotspot and other machines even XP,Vista can connect to this host hotspot and share files and internet connection. I am able to search for the network (set on host) on my client machine. But how to share files? I don't see any such menu or anything. Also after I have installed connectify on Windows 7, I am not able to connect to internet using data card. It throws error that "Error 31:A A device attached to the system is not functioning". And on client machine, if I connect to data card, as well as connect to wireless network setup by host machine, I no longer am able to access internet, even though the data card is connected. The browser throws error: Please help. Any other utility similar to connectify etc?

  • Default route not on LAN

    - by jarmund
    I have a network that in principle looks like this: H1---\ /----Inet1 H2---->---GW1---< H3---/ \----GW2-----Inet2 H1 and H2 = Hosts that need access to internet with GW1 Inet1 = Internet link over 3G connection Inet2 = 5GHz link to Internet (not always up) GW1 = Works as a router, automatically picking the "best" connection between Inet1 and Inet2 (the latter via GW2). GW2 = 5GHz wifi router And here's the problem: H3 only needs internet access when Inet2 is up. What i was thinking of doing was a routing table that looks like this: route to GW2 via GW1 default route is via GW2 I first set the route to GW2 via GW1 without a problem. But when i try route add default gw 1.2.3.4 (1.2.3.4 being the IP of GW2), it complains "SIOCADDRT: No such device" Is the problem that the default gw i'm trying to set is not reachable directly? Is there a different approach that would allow me to achieve this? An alternative (and hypothetical) approach: Since H3 will be using a static IP, is it possible to do some magic with iptables on GW1 to forward any packets from H3 to GW3, thereby "tricking" H3 into using GW2 as its default router?

  • Windows 8 & Hyper-V Can't Bridge Wifi Connection

    - by xinunix
    So I have an odd issue that I can't quite figure out... I am running Windows 8 Enterprise on a Dell 6420 laptop. I have a Broadcom 802.11n wireless adapter. I am connected to an home router (Netgear WNDR3700) that is connected to the internet. It is a very simple home network setup. I am trying to stand-up a few VMs in Hyper-V and want the VMs to be able to access the internet over my wireless connection. I have found numerous examples of how to set this up using both External and Internal Virtual Switches but have yet to be able to get it to work on my machine. I have narrowed the issue down to the fact that my host machine always loses internet connection when I bridge my wifi connection (both when it is bridged automatically by windows when I setup an external virtual switch bound to the wifi adapter or if I do it manually by creating an internal virtual switch, right click on it and my wifi network and select "Bridge Connections".) In both cases after the bridge is established, my host machine can no longer connect to the internet. I am not sure where to start with troubleshooting this problem. After the bridge is setup, an ipconfig shows all netowrk devices on the machine as "Media Disconnected". I do know that the wireless adapter is connected to the router b/c it shows the connection as active and full-strength. The only thing I can possibly think of is that this machine also has the Cisco VPN client installed on it which installs a Cisco Virtual Network Adapter. Is it possible that this Cisco Virtual Adapter is causing me issues when I try to bridge? I saw some people had a similar issue with a VirtualBox virtual adapter when trying to share via Hyper-V. Any thoughts or suggestions on how to troubleshoot?

    I am experiencing an odd problem with one specific server at my data centre connecting from my laptop. Basically the server is accessible from other machines in my house, but not from 1 particular laptop which is running windows XP. I have setup tcpdump on the server and wireshark on the laptop, and I can see ping echo request and reply packets that actually make it back to the wireshark on the laptop, but nothing shows in the ping console output like so; $ ping xxx.55.32.255 Pinging xxx.55.32.255 with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out.

  • Using a Linksys Wireless- G Broadband Router for a Wireless Antenna/Adapter?

    - by Alex
    (Warning: I'm not too computer-smart). Just moved fm a home where I used ATT DSL to a home w/ Comcast Cable for internet. Old home had the DSL ethernet wired to my only desktop w/ a 2Wire router for my wireless signal for the laptops. In the new home the signal comes fm cable via a Netgear(300) wireless router (remotely located) & works fine for my laptops. After searching with the network software, my desktop (can't be ethernet wired cuz of location) detects no wireless signal. Desktop is a 2 yr old HP p6311f Pavilion (Windows 7). Can't seem to detect any wireless hardware (ant/adaptr). Maybe I don't have the ability & need to buy a USB wireless antenna? Would the Pavilion come w/ wireless capability out of the box, maybe something inside the tower? No antenna on back. I happen to have a Linksys Wireless router which I plugged in to the desktop (trying both internet & shared ports) & noticed signal action on the router front panel. No internet on desktop though. Can I use this as an antenna for the desktop? Thanks & sorry if my solution is an easy one I'm just missing. Just want internet on the desktop.

  • openvpn& iptables -- portforwarding and gateway

    - by Smith.Lai
    The problem is similar to this scenario: iptables rule still take effect after deleted Scenario: There are several clients(C1~C10) providing some services, such as SSH,HTTP..... The clients are actually a personal computer behind NAT. Their IP might be 192.168.0.x For easily access these machines through internet, I built a OpenVPN server(S1). All the C1~C10 connect to S1 with VPN address 10.8.0.x If A user(U1) wanna access C1 SSH through internet, he can connect to S1 with port "55555", and S1 port forward 55555 to 10.8.0.6:22 echo 1 /proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 55555 -j DNAT --to-destination 10.8.0.6:22 It works well until I mark the following in the openvpn server.conf: I marked this because I think this will make all connection go through S1 ;push "redirect-gateway" |-------(NAT)--------| (C1)--| (INTERNET)----(U1) |-----(VPN)----(S1)--| The C1~C10 have their own path to access internet resource through NAT . The server loading would be heavy if all C1~C10 connection go through S1 (for example, C1 is sending data to C2, or C1 is downloading data from a FTP site). Is there a way to solve this quandary?

  • DD-WRT (WRT54G) and (THOMSON TG782) how to put them togather?

    - by FeRtoll
    Ok so let me explain, i bought WRT54G and successfully installed DD-WRT v24-sp1 (07/26/08) mini-special - build 9994. That's all ok no problems with it all normal functioning. And just to add (i don't need wireless, wireless is turned off always) What i want: ISP's router (TG782) from it's INTERNET port(out) cable "which was before in my pc" is connected to WRT54G's INTERNET port and then from WRT54G LAN port 1 to my pc. The problem: How do i connect and setup all? I have tried many times on many different ways but cant get it to work IF THE CABLE FROM TG782 IS CONNECTED TO WRT54G ON INTERNET PORT. If i connect the TG782 to Lan port 1 on WRT54G and my pc to lan port 2 then all works fine after i setup gateway and all. But i want to connect TG782 to Internet port of WRT54G because i need "Access Restrictions" and this only goes through WAN right? please correct me if i am wrong. What i have tried: This is how i have tried to setup all. The TG782 router ip is 192.168.1.1 And WRT54G ip is 192.168.1.30 so in WRT54G control panel i have setup like this: ----WAN Connection Type---- Connection Type: Automatic Configuration - DHCP STP: Disabled ----Router IP---- Local IP Address: 192.168.1.30 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 (the TG782) ----Network Address Server Settings (DHCP)---- DHCP Type: DHCP Server Start IP Address: 192.168.1.100 Maximum DHCP Users: 6 And this wont work i probably miss something more, if anyone can help i would be thankfull. Also i have to note that i have tried to set my network adapter on pc to use the gateway of WRT54G and ip 192.168.1.102 In short: i cant get it to work normal only as a switch! Thanks for any help! -------EDIT:------- Here is an image which maybe can help: http://img27.imageshack.us/img27/4227/allin1w.jpg

  • VPN from Windows XP to OpenSwan: correct setup?

    - by Gnudiff
    Main question is what I am doing wrong in my OpenSwan or L2TP client setup? I am trying to create a Linux OpenSwan VPN connection from Windows XP machine, using preshared key and the builtin Windows XP L2TP IPsec option. I have followed the instructions in Linux Home networking Wiki for setting up OpenSwan and a guide to making it work with the Windows XP client, but am now stuck. The net setup is as follows: [my windows client, private IP A]<->[f/wall B]<-internet->[g/w X]<->[Linux OpenSwan server Y] A - private subnet /24 B - internet address X - internet address /24 Y - internet address on same subnet as X What I essentially want is for computer with A address to feel and work, as if it was in X subnet for purposes of outgoing and incoming TCP and UDP connections. My OpenSwan setup is as follows: /etc/ipsec.conf (AAA and YYY indicates ip address parts of A and Y addresses): conn net-to-net authby=secret left=B leftsubnet=AAA.AAA.AAA.0/24 leftnexthop=%defaultroute right=Y rightsubnet=YYY.YYY.YYY.0/24 rightnexthop=B auto=start the secret in /etc/ipsec.secrets is listed as: B Y : PSK "0xMysecretkey" where B & Y stand for respective IP adresses of gateway B and linux server Y My L2TP WinXP setup is: IP of destination: Y don't prompt for username security options: typical, require secured pass, don't require data encryption, IPSec PSK set to 0xMysecretkey networking options: VPN Type: L2TP IPSec VPN; TCPIP protocol (with automatic IP address assignment) and QOS packet schedulers enabled The error I get from Windows client is 789: "error during initial negotiation"

  • Cisco QoS Guidance

    - by Kyle Brandt
    I have a 10M connection to the internet that is hooked into a 100M port. I am getting started with QoS, and am hopping for a little guidance on setting it up on a Cisco 3825 router. Right now I am going forward with the idea that I have to implement it on my router, and the provider can't provide QoS for me. How I envision it working is that the QoS will drop or queue packets on my router and that will help prevent a situation where the provider has to start dropping a lot of packets. Right now all I am tasked with is making sure that one of the 3 LANs gets a certain slice (say 3M for Gig Lan1) of the 10M internet connection (But ideally this will be more flexible in the Future). 10M Internet on 100M port on HWIC-4ESW +-----------------------+ | | Gig Lan1 | Cisco 3825 | Lan3 on HWIC-4ESW | | +-----------------------+ Gig Lan2 I need to learn more about QoS, but having a target technology and maybe example configuration will help me wrap my head around the reading I am doing a little more. Which Cisco QoS Technology do you recommend for this particular situation? Have a basic sample config of how this might work? Right now the 10M line is not congested, so this more to have something in place in case it starts to become mildly congested in the future. I do have VOIP at one location connected to this one over the Internet that goes through a VPN tunnel. Everything else that is between this location and other offices is on a separate MPLS network.

  • Did a recent WinXP update break CD/DVD read speeds? SP2/SP3

    - by quack quixote
    I have two systems with fresh installations of Windows XP Pro SP3 (SP3 slipstreamed into the installer; fully updated after install). One's a refurbished 2.4GHz Pentium4 system; the other is a new 1.6GHz Atom330 build. Both have brand-new dual-layer CD/DVD burners (one's a LiteOn IDE, the other an LG SATA). Both take a really looooong time to read a single-layer DVD in Windows with Cygwin tools. Specifically, 40 minutes or more. I burn backup data to single-layer DVD+/-R and use MD5 hashes for data verification (made with the standard md5sum tool in Unix or Cygwin). The hashes are burned to disc with the data files, and I use this command to verify: $ cd /path/to/disc/mountpoint ; time md5sum -c < md5.txt Here's how long that takes to run on a full single-layer DVD+/-R disc: Old system (WinXP SP2, 1.8GHz Athlon 2500+, last summer): ~10 minutes Old system (Ubuntu 9.04, 1.8GHz Athlon 2500+): ~10 minutes Old system (Debian 5, dual 550MHz P3): ~10 minutes New Pentium4 system (running Ubuntu 9.04): ~5 minutes New Pentium4 system (running WinXP SP3, file copy from Win Explorer): ~6 minutes New Atom330 system (running WinXP SP3, file copy from Win Explorer): ~6 minutes Now the weird stuff: Old system (WinXP SP2, 1.8GHz Athlon 2500+, today): ~25 minutes New Pentium4 system (running WinXP SP3, read from Cygwin): ~40-50 minutes (?!!) New Atom330 system (running WinXP SP3, read from Cygwin): ~40 minutes (can do it in ~30 minutes ...if i have another program spin up the drive first) Since both systems will copy files in 6 minutes using Windows Explorer, I know it's not a hardware problem. Windows just never spins up the drive during the Cygwin read, so it stays super-slow the whole time. Other programs like EAC and DVD Decrypter seem to spin up the disc just fine during their processing. DMA is enabled on both systems. (Can confirm in Windows' Device Manager on the Atom330, not on the P4.) Nero's DriveSpeed tool doesn't seem to have any effect. Copy times are comparable from commandline with Windows' xcopy. Copying with Cygwin's cp looks more like the problem state -- it will spin up the drive for a short time, never reaches full speed, and lets it spin back down again for most of the copy. What I need is to get full read speeds from Cygwin. Is this a known issue with SP3 or some other recent Windows update? Any other ideas? Update: More testing; Windows will spin up the drive when data is copied with Windows tools, but not when read in place or copied with Cygwin tools. It doesn't make sense to me that Windows spins up the drive for copying, but not for other reads. Might be more of a Cygwin problem? Update 2: GUI activity is sluggish during the problem state -- during the Cygwin verifies, there's a slight but noticable delay when dragging windows or icons around on the desktop, switching windows, Alt-Tabbing through open applications, opening new windows, etc. It reminds me of the delay when opening a Windows Explorer window on My Computer just after inserting a DVD. I've tried updating Cygwin (from 1.5.x to 1.7.x), but no change in the problem behavior. I've also noticed this issue occurs on WinXP SP2, but it's not exactly the same -- some spin-up occurs, so the read happens in ~25-30 minutes instead of 40+. The SP2 system used to run the verifies in ~10 minutes, and when it first changed (not sure exactly when, maybe in late November or early December 2009) I thought it was dying hardware. This is why I suspect an official update of breaking this functionality; this has worked for years on that SP2 box.

  • Balancing internal services using a Cisco CSS 11501

    - by Ladadadada
    First, the background to the problem: I have a Cisco CSS11501 that I am using to load balance a few web servers. These web servers have two network interfaces, one internal and one external and we are sending the requests to the internal interface. We have the CSS configured to do NAT because our webservers need to see the client's IP address. Because the TCP packets hit the webservers with a source address on the Internet, the webserver tries to send the packet back to the client over the external interface and not through the load balancer. In order to stop these requests being sent back out to the Internet via the external interface, we added a routing rule on these boxes so that all traffic with a source address on the internet will use the load balancer as the gateway. This part works fine. What I would also like to to is use the CSS as a load balancer for internal services such as our MySQL slaves. When I do this, I run into a similar problem; the TCP connection goes from the web server to the load balancer and then from the load balancer to the MySQL slave but the CSS spoofs a source address of the original webserver. The MySQL slave then tries to send the response directly to the webserver via the internal network and not via the load balancer. The ideal solution would be to tell the CSS not to do source address spoofing on the internal network and only do it for requests originating on the Internet. Is this possible ? Failing that, is there a way of directing the load balanced traffic back through the load balancer while keeping the other traffic (say SSH) purely on the internal network ? Is there another way of using the CSS11501 to load balance internal services ?

  • Using Round Robin DNS on simple VPN setup

    - by dannymcc
    We have two internet connections which are load balanced to share the load between the two. We set this up after one of the internet provider proved to be less than reliable but great speed and latency wise when it is working. We'd rather utilise both connections as much as possible rather than leave one idle until the other drops out. We have a number of remote workers who occasionally need to connect via VPN from their laptops or iPads, we also have a small number of permanent LAN to LAN tunnels running from smaller branches. Originally we only had one internet connection and used one of our static IP addresses for all VPN users. Now that we have two internet connections running all of the time I am trying to make sure that the VPN is available to our team regardless of which connection drops. So my solution is to create two A records for our domain name with a value of vpn. and the two static IP addresses from each peer. Is this a sensible way of achieving this? Should I expect higher latency due to packets being lost if one peer fails and some packets still get routed to it anyway? A brief mockup of the setup I have:

  • Typical outbound port list for guest access?

    - by Steve
    I manage a weekly rental house that includes wireless Internet access. I've allowed all outbound ports on my router but my ISP has disabled my Internet access twice now because guests have downloaded (or served up) copyrighted content. So I'd like to institute some port filtering to discourage p2p sharing (see disclaimer below). But I don't want to inconvenience the 99.9% of folks who keep things above-board. My question is, what outbound ports are typically open for rental/hotel wireless Internet access, or where can I find such a list? TCP 80,443,25,110 at a minimum. Though my own email service uses 995 and 465 for SSL, some may use IMAP, I personally use SSH and FTP, so I'll open those. Roughly I figure I need to open access to privileged ports, and close 1024 & above. Is there a whitelist I should institute for commonly used high ports? And does it make sense to block UDP 1024 ? Disclaimer: I realize anyone replying to this message could circumvent the port filtering and share content to their heart's content. I do not need comprehensive p2p blocking, which requires more than a port whitelist. Anyone staying at the house shoulders the responsibility for their Internet use, per the rental contract. Also anyone savvy enough to circumvent the port filters would hopefully be savvy enough to use some sort of peer blocking, thereby preventing the ISP from taking down the service.
