• Install VPN client problem

  - by Andrey

  I'm trying to install VPN client Shrew, in the process of installation an error occurs. Error 0x800f0203: Couldn't install the network component. It occurs when the installer tries to execute C:\Program Files\ShrewSoft\VPN Client\netcfg.exe -add service vflt C:\Program Files\ShrewSoft\VPN Client\drivers\vfilter.inf Anti-virus, firewall, etc. - are disabled. Run from administrator. Installing vfilter.inf in manual mode, but it's nowhere leads. A similar situation with the Cisco VPN client. Need a VPN client supports a group authorization, and import the settings from pcf format. I'll be glad to any advice!

• Cisco ASA Hairpinning with Dynamic IP

  - by Joseph Sturtevant

  I currently have my Cisco ASA 5505 firewall configured to forward port 80 from the outside interface to a host on my dmz interface. I also need to allow clients on my inside interface to access the host in the dmz by entering the public ip / dns record in their browsers. I was able to do that by following the instructions here, resulting in the following configuration: static (dmz,outside) tcp interface www 192.168.1.5 www netmask 255.255.255.255 static (dmz,inside) tcp 74.125.45.100 www 192.168.1.5 www netmask 255.255.255.255 (Where 74.125.45.100 is my public IP and 192.168.1.5 is the IP of the dmz host) This works great except for the fact that my network has a dynamic public IP and this configuration will therefore break as soon as my public IP changes. Is there a way to do what I want with a dynamic ip? Note: Adding an internal DNS record won't solve my problem since I have multiple dmz hosts mapped to different ports on the public IP.

• TMG Forefront Proxy blocking internal HTTP requests

  - by Pascal

  I have TMG Forefront with Proxy installed and configured. However, whenever I make internal HTTP requested to servers on the internal network with a fully qualified dns name, the proxy denies the connection. Denied Connection FRW-02 18/03/2011 20:06:37 Log type: Web Proxy (Forward) Status: 12202 Forefront TMG denied the specified Uniform Resource Locator (URL). Rule: Default rule Source: Internal (10.50.75.21:21492) Destination: Internal (10.50.75.10:8080) Request: GET http://app-01.mydomain.com.br:9871/internalwebserver_deploy/MyServiceService.svc?wsdl Filter information: Req ID: 0a157279; Compression: client=No, server=No, compress rate=0% decompress rate=0% Protocol: http User: anonymous How can I get around this block? This is an internal call, so it should block it. If I use only http://app-01:9871/internalwebserver_deploy/MyServiceService.svc?wsdl, without the domain after the server name, then it doesn't get blocked. 10.50.75.10 is the firewall's ip, and the internal network's gateway.

• Getting 0x80070043 error when accessing Samba share from Windows 7

  - by FelixM

  I created a Samba share on my new Ubuntu 10.04 machine. When I try to access it from a Windows 7 client, I get network error 0x80070043 (The network path not found). However, I get this error when I click on the share in the Windows Explorer, so it seems that Windows does find the path. I already enabled NTLMv1, disabled 128bit security and made sure that NetBIOS is running. I briefly disabled the Windows firewall, it didn't make a difference. What could be the problem?

• XenServer 5.6.1-fp1. Can't get network working

  - by bakytn

  I have a PC where XenServer 5.6.1 fp-1 has been successfully installed. I've manually set the network settings: 192.168.1.50 255.255.255.0 192.168.1.1 but it's set to xenbr0 iface. While eth0 is empty. When I click on "Configure Management Inteface" it shows that eth0 is connected. But when I ping a default gateway (which is 100% should be accessible) it fails. I used to another shell (Alt+F3) and logged as root. I also failed to ping. with both: ping -I eth0 192.168.1.1 and ping -I xenbr0 192.168.1.1 Be assured that: Cable works Ethernet adapter is 100% functional (prev OS was Ubuntu it was working) There is no firewall rule to deny anything. (everything is allowed)

• Port Forwarding on 80 vs. 8080

  - by Chadworthington

  I am able to access this url (Don't bother clicking on it, it's just an example): http://my.url.com/ This web site works: http://localhost:8080/tfs/web/ I setup my router to forward port 80 to the PC hosting the web site. I also forward port 8080 to the same box. But when I try to access this url I get the eror "Page Cannot be displayed:" http://my.url.com:8080/tfs/web/ I fwded port 8080 the same way I fwded port 80. I also turned off Windows Firewall, in case it was blocking port 8080. Any theories why port 80 works but 8080 does not?

• Firefox 3.5.6 causes entire computer to freeze

  - by Anthony Aziz

  Here's the situation: Environment: Just installed a fresh copy of Win7 Pro 32-bit to NTFS partition on 750GB SATA drive Hardware: E8400 3GHz ASUS P5QL Pro 4GB DDR2 1066 RAM EVGA 9800 GTX+ Plenty of cooling, no problems with hardware before Data is stored on a separate partition, including My Documents No security software is yet installed No extensions installed yet Problem: While using Firefox, sometimes the entire computer will freeze/hang. I get no mouse or keyboard input, can't CTRL+ALT+DEL, no "not responding" indication, just a static image on my display. My drivers are all up to date as far as I'm aware (I just installed this copy of Windows last week). I first noticed this when trying to install Xmarks. I went to the Xmarks site and tried to install and it would freeze. I managed to get it installed (Safe mode and the Mozilla addon site worked), but when I go to configure it (log in, etc), the computer freezes. I don't think it's a matter of usage time or memory issues, because while testing, I browsed wallpaper galleries for about 30 minutes, sometimes as many as 12-15 tabs open at a time, without issue. Sometimes I won't even try to install Xmarks at it will hang. I can install (some) other extensions, the only one I've tried is download status bar (which works). What I've done to try to fix: Restarted (duh) Windows safe mode Completely remove Firefox and install it to a new directory, according to Mozilla's KB (I haven't tried the profile manager, though I assume this does the same thing, except perhaps more thoroughly) Some BIOS changes, including Power options, disabling oveclocking (it was a modest overclock on the CPU, which has run Win7 beta and RC for almost a year now) Memtest Used another Windows user profile, same tragic results I'm STUCK now, with no idea what to do. I'm using Chrome as my main browser at the moment, but that's not something I want to be stuck with. I like Firefox and want to use it. I'm going to try creating a new profile first. One thing I did notice: I started leaving task manager and performance monitor open when anticipating (but dreading) a freeze. firefox.exe had low CPU and low memory, but it looked like overall disk usage was seeing some spikes on the small graph Performance Monitor gives you. I saw on one blog post a fellow using XP moved his Local Settings directory from a separate drive to his main drive, and that solved it, but I don't think my AppData directory is on my D: drive, and that's on the same physical device anyways. Still, something that might be worth trying. I'd extremely appreciate any help. Thanks very much. I really don't want to reinstall Windows from scratch again :( Anthony Aziz

• How to set up a mini call center?

  - by Ralph

  I'm trying to figure out how to set up a miniature call center for a small business. Like, for 1-4 people to take calls, but hopefully expandable to more. We want to accept nation-wide calls, and then I guess distribute the calls among the available agents. If no one is available, I guess it should either put them in a queue and play some annoying music for them, or forward to call to an agent who has least-recently taken a call who can then quickly answer and say "please hold" until they're done their call. We want to have one phone number that customers can call. I guess we then need some kind of ACD system which would take each call and forward it to an agent based on some algorithm? Then we would need to purchase a separate phone line for each agent, plus one just for the distributor? Or do we need several "extra" lines to maintain a queue (one for each customer waiting too)? This "ACD" thing, is it just a device that you would plug a phone line into (or several?), and maybe connect to a computer, aided by some software? Or is a subscription thing that I would need from my local telephone provider? Next, the business we're running, the callers will be repeat customers. It would be helpful to automatically pull up their profile based on the incoming number. The "software" our agents will be running will just be a website where they can log in (preferably from home) and then enter some information they would obtain through the call. So, the system would have to somehow interface with the website if possible. If not, we'll just have to ask each customer for an identifier (phone number, username, customer number, or something). Is this possible? I guess each computer would need a device that the call would pass through, and then if I can somehow hook into that, then I can write some software that will interface with the site. So, where do I start? What hardware do we need to buy? What subscriptions do we need? We were thinking this magicJack might help us in accepting long-distance calls for cheaper, but my understanding is that they provide you with some weird-looking number, is there a way we could "mask" it with our toll-free number? And then pass the incoming calls through the distributor system, which would then get passed to the call-accepting device which would both allow an agent to answer the call and have a software hook? (I realize this might be partially out of the scope of SU, but I wasn't sure where else to ask. It is about computer(-aided) hardware and software anyway.) P.S.: I don't need any of that "press 1 to talk to..." or "say xyz to..." junk. Just a straight-forward, connect-to-next-available-agent system.

• Device Manager in read-only remote mode when local

  - by Luke Puplett

  Hello - since configuring a Windows Web Server 2008 R2 x64 to be hardened for an internet-facing deployment I receive this: "Device Manager is running in read-only mode because you are running it on a remote computer." when entering Device Manager. I have tried reversing the changes I have made, such as: Re-adding Client for Microsoft Networks Re-enabling NetBIOS over TCP-IP Re-adding File and Printer Sharing Disabling the Windows Firewall in all profiles (public, domain, private) I get no joy. It looks like a Microsoft ballsup. I'll try and use Process Monitor to have a look. Google returns only 1 page for this error. Luke

• Windows 7 Enterprise MAK needs Reactivation?

  - by chris

  I have a VMware image that contains our "standard workstation" where I do a lot of testing. I used a Windows 7 Enterprise MAK key (from MSDN) for activation because the doc said that MAK keys don't have to be reactivated when the hardware changes. Activation was done with slmgr.vbs /ipk LICENSE-KEY slmgr.vbs /ato Now after some testing where the virtual hw was changed it says it "needs to activate because the hw has changed". What did I do wrong?

• Problem virtualizing Ubuntu 10.04 32 bit on VirtualBox 3.1 on Windows Vista 64 bit

  - by Adam Siddhi

  Software & Hardware Setup Host System : Windows Vista Home Premium SP1 64 bit Guest : Ubuntu 10.04 (ubuntu-10.04-desktop-i386.iso) 32 bit VM : VirtualBox 3.1.8 Hardware : Intel Core 2 Duo T6400 4GB SDRAM What Happened I followed the tutorial called Installing Ubuntu inside Windows using VirtualBox located here: www.psychocats.net/ubuntu/virtualbox At first I downloaded ubuntu-10.04-desktop-amd64.iso because I figured that it would be a perfect fit with my Vista 64 OS. I was wrong because it turns out the my Intel Core 2 Duo T6400 CPU does not have Intel® Virtualization Technology. So I had to go with the ubuntu-10.04-desktop-i386.iso which is 32 bit. This got me to the point where I could actually create the Ubuntu VM. So I set up the VM in VirtualBox (according to the tutorial I was following) to prepare for the Ubuntu 10.04 virtualization. Please go to my Picassa web album to see the screen shots of my VM settings and Ubuntu boot process so you can see what I experienced (they appear in the order that I experienced them in). www.picasaweb.google.com/rubysiddhi/ProblemVirtualizingUbuntu100432BitOnVirtualBox31OnWindowsVista64# The first 17 images show the VM settings. The last 8 show my attempt at virtualizing Ubuntu 10.04. You can see booting up but ultimately failing. The Specifics The one error message I got was: (process:210): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0) It appeared on a black screen that sort of looked like a Windows console screen but with out the c:\ or the ability to type. Then this error message got more complex when tons of text appeared in the screen. Pictures 23 - 25 in the album show this text. I should also mention that I found this post in the Ubuntu forums by zonination who seemed to have similar problems to mine even though they had a different set up. The main issue I think zonination and me may be having is the fact that we can not change the color mode to 32 bit while it is booting. I think the 16 bit color mode maybe making Ubuntu fail. Not certain though. Well I hope I explained my problem thoroughly and clearly. Thanks for the tutorial. It got me started but, now I hope to finish this process so I can start developing in Ubuntu. OH by the way if you want to actually see what happened play by play (with some classical in the background) check out the video I made over here: http://www.youtube.com/watch?v=XMbbm5E_0Xw Thanks!

• VPN for a small organization

  - by user24091

  I am in charge of a small office network that has < 10 users. I want to be able to offer them access to the network from their home internet connections. At the moment we have a regular ADSL-router-firewall to provide local network access and a fixed IP address. I know there are enterprise-level VPN solutions, but these obviously won't be available to us because of the cost and complexity. What small-scale solutions are around that you could recommend, what would we need to deploy on the client side, and what would the clients need to do to access the VPN? Simplicity and low cost need to be the keys here. Thanks

• setup Zyxel USG 20W as L2TP VPN Server

  - by Massimo

  I've a Zywall USG 20W (wireless disabled) behind a router supplied by the ISP. All ports (both TCP and UDP) on the ISP router are forwarded to the 20W. I'm trying to configure an L2TP VPN to be used by Windows Xp / 7 with Microsoft native client. This was working before with a different firewall, so I'm pretty sure that all the required packets are flowing to the 20W. I followed a tutorial from the italian Zyxel Website, but I cannot get the VPN to work. Always cannot pass phase 2, and I see the following on the log: [ID]: Tunnel [Default_L2TP_VPN_Connection] Phase 2 local policy mismatch Phase 1 goes fine. In Windows the error is always 788. This happens regardless the proposals I set in the phase 1 and 2 setting. What should I check ? Is there any way to get more detailed diagnostic info (policy mismatch is too generic) ? Thanks a lot to whom may help. Massimo.

• Linksys WRT54GC v2.0 - all connection lights flashing

  - by JC Denton

  I have just received a Linksys WRT54GC router of a friend. Apperantly it has stopped working. All lights on it are flashing apart from the power and wireless light. I have read of similar issues online but not ones describing the same set of lights flashing. I have tried connecting to the device over ethernet but failed. It's no longer accessible over wireless either. I've also tried to run the linksys utility on the cd but it failed to detect the presence of the device (attempted over ethernet, firewall switched off). I've tried pressing the reset button for 30 seconds and disconnection the power cable for 30 seconds but to no avail. Thanks for any thoughts

• DD-WRT Router acting as a Switch and Wi-Fi AP

  - by dotnetchris

  Recently I upgraded to Comcast Business and their modem has a built-in router so I took off my DD-WRT router and moved to a location in my home where I needed more ports and Wi-Fi (preferably without running new Ethernet cables since it's 50-100 foot run through floor and ceilings). I have my network cable from my Comcast modem going into Port 1 of my DD-WRT router with Port 2 and 3 being networked PCs. I have DD-WRT setup as a DHCP forwarder with the firewall disabled. This lets my all of my devices access the network fine. Is the correct the way to do this? Or is this a less optimal solution and it should be done in a slightly different way?

• network design to segregate public and staff

  - by barb

  My current setup has: a pfsense firewall with 4 NICs and potential for a 5th 1 48 port 3com switch, 1 24 port HP switch, willing to purchase more subnet 1) edge (Windows Server 2003 for vpn through routing and remote access) and subnet 2) LAN with one WS2003 domain controller/dns/wins etc., one WS2008 file server, one WS2003 running Vipre anti-virus and Time Limit Manager which controls client computer use, and about 50 pcs I am looking for a network design for separating clients and staff. I could do two totally isolated subnets, but I'm wondering if there is anything in between so that staff and clients could share some resources such as printers and anti-virus servers, staff could access client resources, but not vice versa. I guess what I'm asking is can you configure subnets and/or vlans like this: 1)edge for vpn 2)services available to all other internal networks 3)staff which can access services and clients 4)clients which can access services but not staff By access/non-access, I mean stronger separation than domain usernames and passwords.

• Can't ping host from vmware guest using bridged networking

  - by user199421

  Host is Windows 7 Guest is Ubuntu 11.04 Network adapter is wireless I can ping other computers on the network but not the host. No firewall are involved. Sniffing the traffic with wireshark it looks like both the host and the guest are using the same MAC address. My guest simply doesn't receive a reply when asking for 192.168.1.101 (the host) My router has no problem giving both of them different IP addresses but maybe duplicate MAC address is the problem? It seems logical that both will have the same MAC address (from the host point of view) but it strange that there is no work around for this because otherwise I don't see how the host and guess are supposed to communicate.

• ReadyNAS Duo - FTP home network connectivity issue

  - by dwabyick

  I have a ReadyNas Duo that I recently purchased and configured on my local home network. I'm an AT&T DSL subscriber using their default 2701HG-B Gateway (2Wire) wireless router. Basically, I have managed to configure my ReadyNAS, and can access HTTP shares and WINS shares just fine, but cannot get access to it via FTP. I've enabled it in the 'Standard File Protocols' section in the UI, and made a share have read/write default access via FTP. My settings: Port: 21 Authentication mode: User Allow upload resumes: Yes Passive ports: 1024-65535 Masquerade as: (empty, but I've tried the internal IP address). I've even poked around at my router, which has a firewall, and even tried to poke a hole for the 'FTP Server'app for the ReadyNAS. Doesn't seem like I should need to do this, or should. Any ideas what else to check? Thanks! -Daniel

• Issues in getting Synergy setup

  - by chris

  For some reason I cannot get things working when the Linux box is the server and the macbook pro is the client. However I can get things working just fine in the inverse, unfortunately since the macbook is not the primary machine, and not powered on all the time, the later setup won't work. Here is the error that I am getting: started client connecting to '10.0.1.4': 10.0.1.4:24800 The only firewall that I have is the one on the router, so since things work with the macbook as the server I am pretty sure that is not where the problem is. Here is the .synergy.conf file section: screens Chris-MacBook-Pro: # I have tried this with the .local as well chris-archlinux.local: end section: links Chris-MacBook-Pro: right = chris-archlinux.local chris-archlinux.local: left = Chris-MacBook-Pro.local end ** Update: I should also add that I can ping the linux machine from the mac. To try get things working, I have also prevented the hosts.deny/.allow files from blocking anything. An ideas to where the problem could be?

• Exchange 2003 Outlook Anywhere - Changed certificate, not working

  - by JohnyD

  I have a single Exchange 2003 installation which for the past 2 years has been set up for Outlook Anywhere access by means of a self-signed certificate. Just this past week I updated that certificate to a Go Daddy wildcard certificate to allow for use of our web services over https. I've updated the web listener on our ISA 2006 firewall and I can successfully use our services over https. However, my Outlook Anywhere access is now not functioning. I've installed the new wildcard certificate on my XP notebook into the Trusted Root Certificate Store but I keep getting prompted that the password is incorrect. To make things even more confusing I also have OWA set up and this works fine with the new certificate. Any ideas as to what I'm doing wrong?

• Dedicate a NIC to a Virtualbox VM

  - by John Gardeniers

  On a machine with multiple NICs, running either Windows or Linux, is it possible to dedicate a NIC to a VM such that the host won't even try to use it for itself? I suspect it isn't even possible but if it is, which OS and version and just how would I set it up? The reason for this, apart from academic curiosity, is that I'm trying to set up a network lab for testing purposes. I currently have only a single spare machine, otherwise this wouldn't be an issue. One of the VMs will be the firewall for this lab network, so will need a dedicated NIC for the WAN interface. Neither ESXi nor Xen server will run on the machine, so I have to use a host OS.
