  • Why PowerConnect and Juniper are so rare ? Why do enterprises stick with Cisco ?

    - by Kedare
    Hello ! I have a little question, I'm actually studing in IT in France, and when looking on alternative on the very [...] very expensive Cisco equipment, I've found Juniper and DELL PowerConnect pretty attractive on features and price, but I rarely see something else than the classics Cisco/LinkSys, HP Procurve and Netgear.. Why it's so rare to find those switch ? They looks really great but... I've never seen any Juniper or Powerconnect... Why do enterprises stick with the expensive Cisco ? I've tried to find how to buy both, it's quite easy with PowerConnect, everything is on the DELL website, but it looks it's very hard to find Juniper equipment in France :( Thank you !

  • Creating a network link between 2 very close buildings

    - by Daniel Johnson
    I have a charity who have two adjacent medium sized modern detached houses (in the UK): the buildings stand next to each other and are less than 5 metres apart. They have DSL connected to a single computer in one of the buildings. They want to add a network with wireless, and want it to work across both buildings. Being a charity they need to keep costs down. The network would be used for sharing Word documents, e-mail, browsing and skyping. My initial thoughts were to connect the buildings with fibre. So: Option 1 Use fibre between the buildings. Sufficient cable and two TP-LINK MC100CM Fast Ethernet Media Converters. Cost ~£80.00. But there is the extra cost and hassle of running the cable down and up the external walls, lifting and relaying paving, and burying underground. Never having fitted fibre I'm also a little worried about going up the wall and then bending the cable at 90 degrees to go through the wall and into the building. Option 2 Use two TP-Link TL-WA7510N High Powered Outdoor 5Ghz 15dBi Wireless antennas to connect the buildings. There is a clear line of sight at first floor level. Cost ~£100. And much easier to fit than fibre! Is using the TL-WA7510Ns overkill? Is there something more suitable? I had hoped to use some Netgear stuff, e.g. two DGN2200, one in each house and also use them to provide the wireless link between the buildings. However, in bridge mode wireless client association is not available and repeater mode with client association only supports WEP security which isn't strong enough. Is there something similar that would be up to the job? Option 3 Connect the buildings with UTP cable. My concerns here are risk of electric shock due to a difference of potential between the buildings (or are they so close this shouldn't be an issue) and protection from lightning strikes. Is fitting lighting arrestors expensive? And what can be done to ameliorate against the risk of shock? This all falls outside my area of expertise so I would really appreciate some advice.

  • How to find on the Windows 7 who and when use(d) a certain share?

    - by John Thomas
    We have a workstation using Win7 on a LAN with a domain. On that workstation we set up some network shares. Can we find who used (user name and/or computer name) and when the shares? Note that we know about Computer Management System Tools Shared Folders Open Files. We don't want to see so much real-time who's using the shares but we are interested more in a logging solution, ideally interpreting / using the data from Win7's Event Viewer.

  • How to use 2 or more internet connections on the same network?

    - by Rogue
    Living in a joint family we have 3 internet connections, each floor has one internet connection which is split per floor. Each internet connection is shared between 4-5 computers using a switch per floor. Each of these internet sharing networks are independent of each other. What I want to achieve here is a local network (for local messenger and file sharing) that can combine all the 3 independent networks, problem is that whenever I try to do that the whole network tends to use just one internet connection. I have all the necessary hardware. How do I solve this problem, one approach could be that I could get one PC to act as a server and bridge the internet connections and then the whole network would have to access the internet through this server. Theoretically this could be possible but I have never tried this approach in real life. Also if certain computers need be restricted from internet access how would this be possible on the same network?

  • dnsmasq local network works for some but hostnames are not resolving for others

    - by prggmr
    I have set up a local network and it seems that some of us can use it properly while others can't. The problem seems to be that the local hostnames I setup don't get resolved for everyone. To overview how the network is setup: I am running an Ubuntu 10.01 server using dnsmasq, this server is setup to act as our primary DNS server, configured via our router. dnsmasq is configured using the options of domain-needed bogus-priv I use the /etc/hosts file to determain the hostnames 192.168.1.10 ra.xsi 192.168.1.10 test.xsi From my machine: If I dig the hostnames they resolve properly ; <<>> DiG 9.4.3-P1 <<>> ra.xsi ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 61671 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;ra.xsi.

  • Uploading with browser makes all other browser tabs and devices disconnect

    - by fabsenet
    Whenever I upload a video to YouTube all other browser tabs behave like there is no connection at all. It even affects my phone and other computers on the network therefor I think it has to do with my router. When the upload is done everything works normally again. I never observed this behavior with any other upload. My router is a Fritz!Box 7390 and my uploading PC is connected through a 1000mb/s switch (wired) to the router. Uploading through another browser does not change anything. I understand that other sites become slow as the network resources are limited, but stopping altogether feels wrong. speed.io measures for my internet connection: 40.894 Kbit/s down, 2.685 Kbit/s up, 29 ms ping, 2.048 con/m connects

  • Forward all traffic from one IP to another Ip on OS X

    - by Josh
    This is related to this question I just asked... I have two IP address on my iMac I want to "bridge". I'm not sure what the proper terminology is... here's the situation. My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface. If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command. Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

  • Extending a home wireless network using two routers running tomato

    - by jalperin
    I have two Asus RT-N16 routers each flashed with Tomato (actually Tomato USB). UPSTAIRS: Router 'A' (located upstairs) is connected to the internet via the WAN port and connected via a LAN port to a 10/100/1000 switch (Switch A). Several desktops are also attached to Switch A. Router A uses IP 192.168.1.1. DOWNSTAIRS: I've just acquired Router 'B' and set it to IP 192.168.1.2. I have a cable running from Switch A downstairs to another switch (Switch B). Tivo, a blu-ray player and a Mac are connected to Switch B. My plan was to connect Router B to Switch B so that I have improved wireless access downstairs. (The wireless signal from Router A gets weak downstairs in a number of locations.) How should I configure Router B so that all devices in the house can see and talk to one another? I know that I need to change DHCP on Router B so that it doesn't cover the same range as DHCP on Router A. Should I be using WDS on the two routers, or is that unnecessary since I already have a wired connection between the two routers? Any other thoughts or suggestions? Thanks! --Jeff

  • How can I change the binding order of network adapters in Windows 7?

    - by Chris Farmer
    The end goal here is that I am trying to install an Oracle 10g server on my Windows 7 x64 dev box. I use DHCP, and the Oracle installer is throwing up this warning: Checking Network Configuration requirements ... Check complete. The overall result of this check is: Failed <<<< Problem: The install has detected that the primary IP address of the system is DHCP-assigned. Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP. I have installed the loopback adapter, but I am not sure how to make it the primary network adapter. I see this Microsoft KB article on the subject but it's Windows XP-oriented, and I can't seem to find a comparable one for Windows 7. Some of the options it talks about don't seem to be present in the views of the adapters that I see. So, how can I make the loopback adapter become the primary adapter?

  • Wired to wireless bridge in Linux

    - by adrianmcmenamin
    I am attempting to set up my Raspberry Pi as a bridge (but I think this is not a question specific to the hardware) - using Debian wheezy. I have a hostapd.conf: (some details changed for security)... interface=wlan0 bridge=br0 driver=nl80211 auth_algs=1 macaddr_acl=0 ignore_broadcast_ssid=0 logger_syslog=-1 logger_syslog_level=0 hw_mode=g ssid=MY_SSID channel=11 wep_default_key=0 wep_key0=MY_KEY wpa=0 (yes, I know WEP is no good) And this in /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp auto br0 iface br0 inet dhcp bridge-ports eth0 wlan0 Everything seems to come up ok, but I cannot associate with the bridged wireless connection - even though the flashing lights on the USB stick suggest packets are being exchanged. I have read somewhere that not all cards/devices will run in hostap mode - they won't pass packets in one direction: is that right? (The info was a bit old)- this my card: [ 3.663245] usb 1-1.3.1: new high-speed USB device number 5 using dwc_otg [ 3.794187] usb 1-1.3.1: New USB device found, idVendor=0cf3, idProduct=9271 [ 3.804321] usb 1-1.3.1: New USB device strings: Mfr=16, Product=32, SerialNumber=48 [ 3.816994] usb 1-1.3.1: Product: USB2.0 WLAN [ 3.823790] usb 1-1.3.1: Manufacturer: ATHEROS [ 3.830645] usb 1-1.3.1: SerialNumber: 12345 So, what have I got wrong here?

  • Using wifi router as bridge to increase signal?

    - by overtherainbow
    A friend of mine lives in an appartment building whose structure is such that wifi signal is very weak. Even a USB key won't work. I was thinking of buying an entry-level wifi router and reconfigure it as a bridge to act as repeater. Would that increase the chance of getting a good signal, or I shouldn't bother? If experience shows that it does improve things significantly, is their another router I should look at besides the Linux-based Linksys models? Thank you.

  • Does anyone know how to "tcpdump" traffic decrypted by Mallory MITM? [migrated]

    - by chriv
    I'm looking for some help in capturing network traffic that I can analyze in Wireshare (or other tools). The tool I'm using is mallory. If anyone is familiar with mallory, I could use some help. I've got it configured and running correctly, but I don't know how to get the output that I want. The setup is on my private network. I have a VM (running Ubuntu 12.04 - precise) with two NICs: eth0 is on my "real" network eth1 is only on my "fake" network, and is using dnsmasq (for DNS and DHCP for other devices on the "fake" network) Effectively eth0 is the "WAN" on my VM, and eth1 is the "LAN" on my VM. I've setup mallory and iptables to intercept, decrypt, encrypt and rewrite all traffic coming in on destination port 443 on eth1. On the device I want intercepted, I have imported the ca.cer that mallory generated as a trusted root certificate. I need to analyze some strange behavior in the HTTPS stream between the client and server, so that's why mallory is setup in between for this MITM. I would like to take the decrypted HTTPS traffic and dump it to either a logfile or a socket in a format compatible with tcpdump/wireshark (so I can collect it later and analyze it). Running tcpdump on eth1 is too soon (it's encrypted), and running tcpdump on eth2 is too late (it's been re-encrypted). Is there a way to make mallory "tcpdump" the decrypted traffic (in both directions)?

  • How can I run a game server on a computer behind a NAT, if I have another computer not behind a NAT?

    - by Macha
    My home connection is part of a large NAT, outside my control. Inside my home, my router has a NAT, under my control. I control a public facing Linux VPS with one IP address, outside my home network. Ideally, what I'd like to do is set something up so that I connect my home computer to my VPS, and after that port X on my VPS leads to port Y on my home computer, for the purposes of running a game server of a game that does not run under Linux. Is this possible?

  • Multiple virtual VLAN interfaces on single NIC (Debian)

    - by RayQuang
    I'm trying to setup multiple virtual interfaces with VLAN's on a single NIC. I'm running Debian Squeeze. Currently this is my /etc/netowrk/interfaces auto eth0.10 iface eth0.10 inet dhcp This gives me a working connection, however I'm not sure how to configure several like these on a single NIC so I can use multiple external IP's. I have tried aliasing the VLAN's like so: iface eth0.10:1 But that was not successful and it said failed to bring up interface. And suggestions would be greatly appreciated :)

  • How to troubleshoot problems sharing internet connection via WiFi on Mac OS X

    - by sprugman
    I'm at a hotel, plugged into their network via ethernet on my MacBook. I want to share the connection via wifi to two other computers. I went to Prefs Sharing and set up internet sharing. I know it's working because my friend with a Mac access the net fine. My friend with the PC can see the network, but can't connect to it. In the sharing prefs, airport options, I chose these options: Channel: Automatic Enable encryption: yes WEP Key length 40-bit password length: 5 chars (as specified in the instructional text) Update: I tried it with encryption turned off, and it works. Of course, I'd rather not do that... Any ideas?

  • Likeliness of obtaining same IP address after restarting a router

    - by ?affael
    My actual objective is to simulate logged IPs of web-site users who are all assumed to use dynamically assigned IPs. There will be two kinds of users: good users who only change IP when the ISP assignes a new one bad users who will restart their router to obtain a new IP So what I would like to understand is what assignment mechanics are usually at work here deciding from what pool of IPs one is chosen and whether the probability is uniformly distributed. I know there is no definite and global answer as this process can be adjusted be the ISP but maybe there is something like a technological frame and common process that allows some plausible assumptions. UPDATE: A bad user will restart the router as often as possible if necessary. So here the central question is how many IP changes on average are necessary to end up with a previously used IP.

  • Windows 7 file sharing password protecting or making stuff available to just me

    - by Carbonara
    Even with the new Homegroup feature I'm still finding the way Windows deals with folder sharing utterly baffling. Here's what I want to do. I have two computers, a PC Desktop and a laptop. I also live in a shared flat with other computer users. I have set up a Homegroup and a Workgroup on the desktop and joined them on the laptop and in the home group I have shared video, music and pictures. This is so that anyone on the network can view pictures and listen to music etc. But I want my Documents folder from my desktop to only be available to me on my laptop and not to anyone else that may be on the network. The Homegroup only allows (from what I can gather from the baffling array of options) sharing with everyone or no one. Is it possible to only allow the laptop to access the documents folder on the desktop? The user name and password are the same on both computers.

  • bluetooth doesn't recognize mouse (and other devices)... sometimes

    - by Angelo
    I have a problem with bluetooth with Vista, running on my MacBook. It often doesn't recognize my wireless Magic Mouse. And I saw that it even doesn't seem to start as the pictogram in the task-bar isn't there most of the time I run Vista. But I'm only an Apple-nerd, so I don't know to much about this issue on Vista. When reinstalling Boothcamp or other updates, then once in a while bluetooth recognizes my own mouse (and other devices from some neighbours... so that implicates that the problem must be the bluetooth function in the first place, not my mouse.) Is there some update for the bluetooth application? Angelo

  • How to install a "virtual" network card on a virtual server?

    - by vikp
    Hi, We have purchased an unmanaged VPS windows hosting solution from one of the UK based companies. We have Windows Server 2008 Standard Edition. We need to install certain third party applications on that server. Unfortunatelly, one of the applications requires a MAC address to be present at all times - this is their way of making sure that software is not pirated (which it isn't). We have tried installing a virtual loopback network card, but this has brought the server down - i.e. we couldn't connect using remote desktop any longer. At the moment we are limited with what we can try. This is an unmanaged solution, therefore any support including restarts is rather costly. Are you aware of any low-risk solutions? Thank you
