  • Modem with support for wired 802.1x

    - by menko
    I'm looking at allowing internet access for only a few scattered users on a school network. One method I'm considering is using 802.1x authentication for the modem. Of course there are simpler options like only allowing specific IP or mac addresses, but policy requires something more secure than this. So, are there any modems with 802.1x wired authentication? All my searching on this yields info about wireless.

  • Hiding mapped drives for all users but letting programs access them

    - by AgainstClint
    What I'm looking for (and not sure if it's possible) is that we have 16 mapped network drives that are mapped when any user logs on, what I would like is to cut this down to just one visible drive yet leaving the other ones still usable to certain programs. I would just un-map them, however one of our constantly used programs writes to almost all of the drive letters so they need to be mapped for just that program, however they do not need to be visible to the user. Is this possible?

  • Determine the percentage of a file that has been ftp'd from client to server

    - by klwillie
    I want to ftp a large file from a Windows client to a Windows server, using their IP addresses. This is on an internet independent network. While the file is transferring, I would like to determine how many bytes have been received by the server. I then would like to use this information to determine in real-time the percentage of the file that has been transferred to the server. Any recommendations as to the ftp command syntax and C# code to achieve this?

  • Wake On LAN on request

    - by honzas
    Hi, I have a small home network with the router capable of running OpenWRT, is there some utility or firewall rule, which can be used to Wake On LAN on request. What I think - if I want to access my media centre (using for example SSH or HTTP) and it is suspended, is it possible to catch the ICMP packet (saying the machine is offline) and send the WOL packet to wakeup the machine and resend the SSH or HTTP request? Thanks

  • Ubuntu X doesn't start

    - by den-javamaniac
    I'm running desktop Ubuntu 9.10 on my Dell laptop. Previously it was Ubuntu 9.04. After some period of time (lets say 3-4 months) my X fails to start automatically after some restart calls. If that takes place my network manager applet doesn't start either (after I do startx). Can any one point out what I'm missing/what's the problem?

  • Wifi interference tool for Mac

    - by Kevin Burke
    This Server Fault blog post shows some tools you can use to view interference on your wireless network: blog.serverfault.com/2012/01/05/a-studied-approach-at-wifi-part-2/. They mention Vistumbler, which only works on PC's. Is there a similar tool I can use to measure wireless interference on a Mac? Also, is it better to be on a channel with many AP's, each with a weak signal, or on a channel with only a few AP's, but a strong signal?

  • Data recovery for Mac

    - by josh3736
    I've got a Mac that won't boot and I'd like to recover whatever data I can before wiping the hard drive and reinstalling. I'm looking for something similar to TRK (which is Windows-centric) — boot from CD, mount the hard drive, and copy to a network share. I just noticed TRK does appear to support HFS+; has anyone had success with this?

  • Sycronizing/deploying scripts across several systems

    - by otto
    I have a few time consuming tasks that I like to spread across several computers. These tasks require running an identical ruby or python script (or series of scripts that call each other) on each machine. The machines will a separate config file telling the script what portion of the task to complete. I want to figure out the best way to syncronize the scripts on these machines prior to running them. Up until now, I have been making changes to a copy of the script on a network share and then copying a fresh copy to each machine when I want to run it. But this is cumbersome and leaves a chance for error ( e.g missing a file on the copy or not clicking "copy and replace"). Lets assume the systems are standard windows machines that are not dedicated to this task and I don't need to run these scripts all the time (so I don't want a solution that runs 24/7 and always keeps them up to date, I'd prefer something that pushes/pulls on command). My thoughts on various options: Simple adaptation of my current workflow: Keep the originals on the network drive, but write a batch file that copies over the latest version of the scripts so everything is a one-click operation. Requires action on each system, but that's not the end of the world (since each one usually needs their configuration file changed slightly too). Put everything in a Mercurial/Git reposotory and pull a fresh copy onto each node. Going straight to the repo from each machine would guarantee a current version (and would have the fringe benefit of allowing edits to the script to be made from any machine). Cons would be that it requires VCS to be installed on each machine and there might be some pains dealing with authentication since I wouldn't use a public repo. Open up write access on a shared folder and write a script to use rsync (or similar) to push the changes out to all of the machines at once. This gets a current version on every machine (though you would have to change the script if you want to omit a machine or add a new one). Possible issue would be that each computer has to allow write access. Dropbox is a reasonable suggestion (and could work well) but I dont want to use an external service and I'd prefer not to have to have dropbox running 24/7 on systems that would normally not need it. Is there something simple that I am missing? Some tool designed expressly for doing this kind of thing? Otherwise I am leaning toward just tying all of the systems into Mercurial since, while it requires extra software, it is a little more robust than writing a batch file (e.g. if I split part of a script into a separate module, Mercurial will know what to do whereas I would have to add a line to the batch file).

  • OS X - forwarding external port to local loopback address

    - by Rory Fitzpatrick
    I have an HTTP service bound to port 8000 that I want to access from another computing on the network, but I can't seem to connect using the external IP address of the machine (e.g. 192.168.0.105). I've checked the OS X firewall isn't running, so I'm assuming the issue is the service is only bound to the IP address 127.0.0.1, and not the external IP address. What would be the easiest way to temporarily forward external connections on port 8000 to 127.0.0.1:8000?

    I am trying to configure a fresh installation of FreeBSD using VMware workstation. I get to a screen where I have to configure the Network Interfaces (some values are set automatically because I've selected DHCP Auto in options) but the hostname is empty and domainname is .localdomain. What values should I write in there?

  • NetBios Name Service requests

    - by Austin Salonen
    I'm noticing on MS Network Monitor a ton of NetBios Name Service broadcasts coming from a particular workstation. When I run netmon on that desktop it cannot resolve the application producing them (but does log them). First question, is this bad? Next question, what could be causing this so we can either move it to a server or stop it entirely?

  • rhn_register through HTTP Proxy with Authentication

    - by kjloh
    Is there any limitation to the proxy authentication support of rhn_register? The proxy of the network I'm on sends the follow 407: HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ) Via: 1.1 VANESSA Proxy-Authenticate: Negotiate Proxy-Authenticate: Kerberos Proxy-Authenticate: NTLM It seems that rhn_register is not able to any of the authentication schemes above. Any advise?

  • HTTP Proxypass of subdomain

    - by enedebe
    I'm trying to install a proxy on my gateway that everything that comes from a subdomain for example sub.mydomain.com goes to an inside server at a :3000 port. I'm installing a redmine server inside my network that has to be reached from outside. Any idea of how to do that? I think in httpd as proxypass, but I don't know how to get just the subdomain name to proxy it. My gateway is currently Clearos machine. Thanks

  • Is there a way to setup a hotspot with a domain name rather than IP address?

    - by WagnerMatosUK
    Basically I've setup a hotspot and its currently being accessed through an IP address. I'd like to use a hostname instead. This is for internal use only, meaning the ODROID device which is being used to as Access Point is connected to the internet via ethernet and only a few devices will access the AP. My setup details: Arch Linux on an ODROID U3 device, using hostapd and dhcp server. PS: I'm quite inexperienced with network so I might be missing something obvious here. Thanks in advance

  • Routing domain over lan [closed]

    - by Buri
    I have server on my local network which is exposed to the internet. I have domain pointed on my IP and setup forwarding. The thing i would like to do is when i access example.com from lan to connection be routed directly on my server, not to the nearest DNS. Things I had in mind were to upgrade router with dd-wrt and setup routing rule, or to setup local DNS. Unfortunately, I'm not familiar with neither of those systems.

  • How do I add categories from another user in outllook 2003 to my list of categories in 2007?

    - by Ernst
    Hi, I'm sharing a contact list with another user on the network, but I'm using outlook 2007 and the other user is using outlook 2003. The other user has assigned many different categories, but I do not get those categories added to the list of categories I can choose from when adding/editing contacts, I can see certain contacts have those categories. How do I add those categories so I can also add them? The shared contacts originate from the other user. Thanks

  • a couple of questions about proxy server,vpn & how they works

    - by Q8Y
    I have a couple of questions that are related to security. Correct me if i'm wrong :) If I want to request something (ex: visiting www.google.com): my computer will request that then it will to the ISP then to my ISP proxy server that will take the request and act as a middle man in this situation ask for the site (www.google.com) and retrieve it then the proxy will send it back to me. I know that its being done like that. So, my question is that, in this situation my ISP knows everything and what I did request, and the proxy server is set by default (when I ask for an internet subscription). So, if I use here another proxy (lets assume that is a highly anonymous and my ISP can't detect my IP address from it), would I visit my ISP and then from my ISP it will redirect me to the new proxy server that I provide? Will it know that there is someone using another proxy? Or will it go to another network rather than my ISP? Because I didn't get the view clearly. This question is related to the first one. When I use a VPN, I know that VPN provides for me a tunneling, encryption and much more features that a proxy can't. So my data is travelling securely and my ISP can't know what I'm doing. But my questions are: From where is the tunneling started? Does it start after I visit the ISP network (since they are the one that are responsible for forwarding my data and requests)? If so, then not all my connection is tunneled in this way, there is a part that is not being tunneled. Since, every time I need to do anything I have to go to my ISP and ask to do that. Correct me if I misunderstand this. I know that VPN can let my computer be virtually in another place and access its resources (ex: be like in my office while I'm in my home. This is done via VPN). If I use a VPN service provider so that I can access the internet securely and without being monitored by my ISP. In this case, where is my encrypted data saved? Is it saved in my ISP or in the VPN service provider? If I use a VPN, does anyone on the internet know what I'm doing or who I am? Even the VPN service provider? Can they know me? I think they should know the person that is asking for this VPN service, am I right?

  • Group Policy is not being applied from Server 2003 to win7 client

    - by John Hoge
    Hi, I'm experimenting with Group Policy settings. My DC is running Server 2003, and the client I am using for this test is running Win7. I've restarted the client a few times, and tried running gpupdate/force for good measure. This machine is in it's own OU with a group policy applied to change one setting, Computer Configuration/Administrative Templates/Network/Offline Files. When I run MMC and look at Local Computer Policy on the client this setting shows up as "not configured". Thanks, John
