• Error installing Network driver

  - by Simon Carpentier

  I'm tring to install NetLimiter 3 (3.0.0.10, x64) on my Windows 7 x64 machine. At the driver installation step, I'm getting an error: Error 0x8004a029: Couldn't install the network component. (InstallNdisIMDriver) UPDATE 2010-09-20: I received a response to my support request: Hi Simon, It seems that problem is rather on your system than in NL3. Too many networking applications (VPN, Virtual computers) are installed on your machine and they are preventing NL3 from proper installation. In order to install NetLimiter 3, try to disable/temporarily remove these apps. Several users had the same problem and shuffling with adapter and networking software helped them. Please, let us know which action helps you (if any). Sincerely, Jan Bilek Any thoughts on this?

• Instant messanger capable of offline messaging & tolerant of network interruptions

  - by Terry

  I am looking for an instant messaging solution to facilitate communications between recovery vehicles in remote rural areas. All the vehicles have internet connections, but they are intermittent depending on location. Ideally we'd like something that has the following features: Offline messaging: messages sent to clients who are offline will be delivered when they next come online, regardless of whether the sender is still online or not. Lightweight: CPU cycles are limited on the machines in these vehicles. A bloated solution will be an issue. Client platform is primarily win32, but support for osx/linux/mobile devices would be a bonus. Non-chatty: Bandwidth is a precious commodity for us, so services which use a minimal amount are ideal. Fault tolerant: We see plenty of packetloss and high latency, so whatever we use needs to be able to function in trying network conditions. I'm not fussed if we use a hosted platform like gtalk/skype/msn/icq/whatever, and likewise I can run a server if need be. Suggestions would be appreciated!

• wireless network with cable modem and access point

  - by hayri

  I have a Scientific Atlanta EPC2203 cable modem and a TP-Link TL-WA500G access point. When I connect my computer directly to modem with a CAT5e cable I have internet connection on my laptop (when i type ipconfig i see my external ip there, provided by isp). So I decided to have wireless network in the flat, allowing other devices to connect as well. I bought this wireless ap (TL-WA500G) configured Wireless security stuff, and connected it to my modem. With that configuration (by default AP has static ip of 192.168.1.254) only my computer can connect to internet over wifi, but not any other device. When I set the IP of AP to Dynamic IP (DHCP) it is the same. How should I change my configuration to enable all wifi devices to connect to internet?

• How should I isolate computers with different roles on a network

  - by fishhead

  I work in an industrial plant and we have one network(physical wire) that us used for both office usage and for process systems. The office computers are only used for typical office needs but occasionally do connect to the process computers to obtain information from a sql server or for some other purpose. A new initiative is in the works and is rolling down hill from corporate and that is to standardize how the the computers are used at work and they would be severely locked down and only a standard set of applications will be allowed to execute. one of the requirements is to also have non office computers isolated from the company domain. our non-office computers are a mix of Man-Machine interfaces and sql-servers all running software that non standard. My question is, how can we divorce the control systems computers from the company domain but still have access to the servers from the company domain. thanks

• Unable to access internal network through PfSense WAN port

  - by Sean

  Our branch office is unable to connect to our internal network for some reason. However we can connect to the branch office domain controller from behind PfSense. The following is our setup: |Branch DC - 192.168.0.101 | |Branch Firewall - 192.168.0.2 | |(Internet) | |Local Firewall - 192.168.3.1 | |PFSense WAN port - 192.168.3.100 |PFSense LAN port - 192.168.1.1 | | DC1 - 192.168.1.2|DC2 - 192.168.1.4 Branch DC can ping and connect to PFSense WebGUI on the WAN port successfully (we set this up using the PfSense documentation). DC1 and DC2 can connect outbound to the Branch DC. There seems to be a rule that prevents internal access on the WAN port. However our rules are set to allow all traffic on the LAN and WAN ports. It would be ideal to just disable the firewall altogether since we already have a firewall but when we do this, PfSense doesn't allow any internal traffic at all. I look forward to any assistance and thank you ahead of time.

• Internet connection slower than network connection speed

  - by Mike Pateras

  I've got a computer connected to a wireless router on a different floor. When I look at the network connection, I'm told the signal strength is low, and that I've got a connection of about 26mbps (often higher). However, my internet connection on that machine is very slow. Speedtests show it at about 1-2mbps, and it really shows when loading pages and video. I have fiber optic internet access, and the machine that's connected to the router/modem via cable gets the 20mbps on speed tests, and is extremely fast in every day use. My question is, is the advertised 26mbps+ connection speed perhaps inaccurate, and that my wireless bandwidth is the likely bottleneck here? Or is the signal strength what's key here? And what might I do about this? Power cycling the router helped a bit, a speed test went as high as 6mbps after doing that.

• Why not all users can log in to a network computer by using <network computer name>/<user name> form

  - by Haris

  There is a file server in my office that is not connected to my office LAN. In this server there are folders that are shared. This server is connected to a switch and a wireless router. Everyone who wants to access this server uses wireless network connection. They log in to this server by providing user name and password registered to the server. Some people can log in to my office file server by providing user name in (the server name)/(user name) format, while other must use (the server IP address)/(user name) format. Why is it like this? I need everyone can access the file server by providing user name in (the server name)/(user name) format. I have tried to change the %SystemRoot%\system32\drivers\etc\hosts file, as some suggested, but it won't work. Any other suggestion?

• Using ADSL Modem/WiFi Router to share existing network wirelessly

  - by joshhunt

  At my uni we have a wired Ethernet connection in our dorms. However, I want to share this connection with my macbook using wifi (so I don't have to be constantly tethered). I am looking at using my DSL G064T ADSL modem/WiFi router as a wifi repeater for the uni network. Is this possible? How would I go about doing this? I understand that it would be possible using a normal Wifi router (seeing as it has an ethernet 'in' port where it would get the external connection from.), so is it just not possible using the router I have? If i need to buy another one, which one would you recommend?

• Using "enterprise" switches in home network?

  - by Industrial

  Hi everyone, After more than 12 years working with computers, I am still way behind when it comes to networking, so please bear with me :) As of this Christmas, the number of computers in my home has increased and it's well about time to upgrade the current network hardware in order to offer LAN connection to all computers. Trying to find a cheap solution, A close friend offered me a great deal on a "enterprise-class" Switch from HP (more LAN ports than I would ever need), at the same price as what a brand new Netgear or D-link Switch with 6/8 ports would cost me in retail. Would it be common sense to get this one and start using it immediately and never again have to worry about running out of LAN connections, or am I taking on a bigger bite than what I could chew?

• Cannot run setups from a vboxsvr mapped network drive on Windows 7 within VirtualBox

  - by Dimitri C.

  I'm trying to run an application setup by double-clicking the setup.exe from within Windows Explorer. The file is located on a mapped network drive, and I'm using Windows 7. This results in the following error message: The specified path does not exist. Check the path, and then try again. The workaround I found is to copy the installer to the main hard drive (c:) and run it from there; however, this is rather inconvenient. The same action did work on Windows 2000, Windows XP and Windows Vista. I have the impression that the problem only occurs with installers, as everything seemed to work fine with regular exe's. Is there anyone who can explain this odd behavior? Update: After some extended tests I noticed that the problem only occurs with a mapped drive of VirtualBox's "shared folders" (cf. vboxsvr). Mapping an SMB drive works fine.

• Homegroup doesn't show other computers, but "Network" does

  - by McPherrinM

  I have a desktop and a laptop (both running windows 7) in my Windows 7 homegroup. The desktop created the homegroup, and the laptop joined it. Both share a few folders. On the laptop, I have no problem accessing the Desktop's shared folders via the "Homegroup" sidebar button in Windows Explorer. However, on the Desktop, I get the message No other homegroup computers are currently available in the homegroup screen. However, if I go to the Network page, I can see the other computer and browse its shared media. These shares were made by right clicking and choosing "Share with Homegroup". I can access the media, so this isn't a big problem, but I'm just confused as to why the Homegroup screen denies the existence of the other computer. Has anybody else encountered and resolved this?

• Toolkit & Habits for Linux Network & System Administration [closed]

  - by slashmais

  I am tasked with the administration of a small office network as well as several workstations running mostly Debian and Ubuntu. There are two servers: one database & print-server, and one backup & file server. Being relatively new to this side of things, knowing enough to help myself to some degree on Linux, I would like to know what software tools and tasks/habits I can use/acquire to learn this field and be effective while doings so. I don't need to know what is the best, just what a newbie sys-admin can use as a starter-pack to learn and use as a base to grow into proper system administration. [edit] What I need is those few basic tools to start with, and the kind of things I need to do regularly, e.g.: which logs to check, when & what to monitor, the kind of 'right' place to start and to which I can ad as I need.

• network topology including many services

  - by mete

  I know this is yet another question on how to setup network but I hope you are not bored of such questions yet. The site is also an office, so it includes windows dc, windows ad, exchange, sql, file sharing, development app servers and other pcs. In addition to office (internal) things, there are both test and prod environments consisting of a web server-app server-sql stack. There is also ftp service open to public. I consider: dmz1 - web server - exchange edge - ftp dmz2 - app server - sql for app server internal - dc and ad - exchange hub and transport - internal file sharing - sql for internal use - app servers for internal use - pcs public - dmz1, only web, ftp and smtp public - dmz2 not possible public - internal not possible dmz1 - dmz2 is possible from web servers to app servers by using http or ajp dmz1 - internal is only possible for exchange, otherwise not possible dmz2 - internal not possible Does this sound ok ? Any other recommendations ? It will be configured using either MS ISA or Jupiter SSG. Thank you.

• Network vulnerability and port scanning services

  - by DigitalRoss

  I'm setting up a periodic port scan and vulnerability scan for a medium-sized network implementing a customer-facing web application. The hosts run CentOS 5.4. I've used tools like Nmap and OpenVAS, but our firewall rules have special cases for connections originating from our own facilities and servers, so really the scan should be done from the outside. Rather than set up a VPS or EC2 server and configuring it with various tools, it seems like this could just be contracted out to a port and vulnerability scanning service. If they do it professionally they may be more up to date than something I set up and let run for a year... Any recommendations or experience doing this?

• Can't access website on local network

  - by Romain

  I have a personal website running on my PC (Ubuntu), connected to the internet through a router. I can connect without any problem to my website when I'm not at home so I guess my router is correctly configured but whem I try to access the site using a local adress at home (192.168.XX.XX), it times out after 30 seconds or so. What tool could I use to find out where is the problem? I have tried a tracert command on my Windows PC but add just a useless line. If it's of any help, my website is running on Tomcat 6 but I don't think the problem is here as it would be weird that the server would be configured to be accessible from the internet but not the local network.

• datacenter network change control best practices

  - by jpolache

  I have been tasked with compiling a list of possible network equipment changes at a data center. The task includes tagging which changes need change control and which don't. Does anyone know of a "best practices" list that I can start from? The methods for doing change control at this data center are well established. The list would be of specific configuration items that should or should not be included in the change control process, of example; static route entries switch port assignments firewall rule additions/changes etc.

• Double VPN Network Authentication

  - by Pyromanci

  I have a project I'm working on and looking for some info. Right now I have a VPN network using Cisco Pix 501's for the vpn clients and a Cisco VPN Concentrator 3000 for the VPN Server. Since the Pix is constantly connected to the vpn, I want to add a extra level of authentication. Meaning when the user on the other end goes to access anything on the VPN they are asked for a username password before the connection is established. I've never done this sort of structure before. So I'm not even sure where to really being or even if my current hardware can do something like this, or if i need to through in some sort of radius/LDAP/Active Directory type server into the mix.

• Windows 7 Printing to a network printer

  - by JohnyV

  We have a 2008 server as our print server. Clients that use windows xp with a logon script to map have no problems printing. When I test printing to a network printer on a windows 7 machine it works fine up to a few machines as soon As i get 12-15 workstations trying to print, when they log in they get the yellow exclamation mark and needs troubleshooting against the printer name. It is being deploy by group policy. I have tried to deploy it by group policy also by group policy preferences and by using a script and i get the same error whatever i try. Does anyone have any suggestions to try and troubleshoot? Once again Windows xp clients have no issues printing at all. It is only windows 7 clients. Thanks

• Script to list current user's mapped network drives

  - by Dmart

  I have a Windows XP/ Server 2003 environment here users have mapped different network drives themselves using arbitrary drive letters. Some of these users do not know how to tell the true UNC path of these drives, and I would like to be able to run a script or program to query those drives and show me the drive letters and the corresponding UNC paths. I would like to see output like "net use" in that user's context so that I can see what drives THEY have mapped. I would need to do this using my own admin account, which is where the difficulty lies. I understand this information would be stored in the HKCU registry? I would love to be able to do this in Powershell, but a vbscript or even a standalone executable would do. Thanks.

• windows firewall and network location switch after establishing a vpn connection

  - by Konrads

  I am looking for a reasonable solution for network location switching after VPN connection is established for Windows 7. The scenario is as follows: For location public (employee plugging in his laptop in hotel, public wi-fi,etc) all inbound connections are restricted, only outbound VPN + www is enabled. Employee then initiates a VPN connection, VPN pushes routes to 10.0.0.0/8 subnet Now I would like to have lax security rules for traffic from/to 10.0.0.0/8 that comes through the VPN interface, while still protecting the laptop from traffic that comes via uplink interface as if it was private. How to achieve this switching and duality? One option I see is switching to IPSec...

• Slow performance over network (Ubuntu)

  - by Filipe Santos

  i did setup this NodeJs TCP Server and tested it with a message flooder. Just to see how the performance of the server is. While the message throughput is great if i run the server and the message flooder on the same computer (ubuntu), the throughput dramaticaly decreases if i start the server on computer1(ubuntu1) and the message flooder on computer2(also ubuntu). Both PC are on the same network. In fact, they are directly connected to each other. I started searching the internet for reasons and i suppose i need to tune TCP on both Ubuntu-pcs but until now i haven't been successfull at all. Has anyone experienced such problems, or could someone help me out? Thanks Here the flooding code: var net=require('net') var client = net.createConnection(5000, "10.0.0.2") client.addListener("connect", function(){ for(var i = 0; i < 1000; i++) { client.write("message "); } })

• Simulating a low-bandwidth, high-latency network connection on Linux

  - by Justin L.

  I'd like to simulate a high-latency, low-bandwidth network connection on my Linux machine. Limiting bandwidth has been discussed before, e.g. here, but I can't find any posts which address limiting both bandwidth and latency. I can get either high latency or low bandwidth using tc. But I haven't been able to combine these into a single connection. In particular, the example rate control script here doesn't work for me: # tc qdisc add dev lo root handle 1:0 netem delay 100ms # tc qdisc add dev lo parent 1:1 handle 10: tbf rate 256kbit buffer 1600 limit 3000 RTNETLINK answers: Operation not supported How can I create a low-bandwidth, high-latency connection, using tc or any other readily-available tool?
