  • How to secure adhoc networks

    - by moshroum1
    What is the right way to secure adhoc networks? WPA_NONE is a cruel hack (doesn’t work most of the time, discards important packets, ..), WEP is not secure and Open… open is open. IPSec is a level to high. Does there exists something which works under linux and wifi?

  • how to change interface ip in ifconfig with /etc/network/interfaces

    - by user2478348
    Hi everybody when modifiying /etc/network/interfaces, saving it and then executing ifconfig i can't see the modification i made..for example here is part of my /etc/network/interfaces: auto wlan1 iface wlan1 inet static address 192.168.0.60 netmask 255.255.255.0 gateway 192.168.0.61 you can see that the IP address of my wlan1 is 192.168.0.60 but when typing ifconfig i have this: wlan1 Link encap:Ethernet HWaddr 00:19:70:0f:c2:9c inet adr:192.168.0.1 Bcast:192.168.0.255 Masque:255.255.255.0 adr inet6: fe80::219:70ff:fe0f:c29c/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Packets reçus:758 erreurs:0 :0 overruns:0 frame:0 TX packets:610 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 Octets reçus:73490 (73.4 KB) Octets transmis:127883 (127.8 KB) (the inet adr:192.168.0.1 and not 198.168.0.60)..if someone can help me I'll be very thankful :)

  • How to serve a webpage on connection to WiFi network

    - by samwatt
    Hi, I would like to be able to serve a local webpage (on a LAN) when someone connects to a WiFi network. This happens quite often in libraries, cafes etc, so i'm sure it can be done, but I have no idea how and can't seem to find much through searching the web. That, and my very limited networking knowledge means I'm hoping you guys can point me in the right direction. Many thanks!

  • Cisco WLAN Controller not pushing out DHCP addresses, what else could it be?

    - by Name
    On our Cisco WLAN Controller web interfaces, in Controller Interfaces, I have made a new interface with these settings: VLAN Identifier 202 IP Address 172.16.202.1 Netmask 255.255.255.0 Gateway 172.16.202.254 Primary DHCP Server 172.16.100.3 Secondary DHCP Server 172.16.100.2 Port: LAG I've also made a new WLAN and assigned it to the above interface. I have saved changes. But our wireless devices, although they seem to authenticate with the WLAN fine, they always get stuck on "obtaining DHCP address", so it seems the WLAN Controller isn't pushing out DHCP addresses to our devices. We do have a DHCP scope for the above in Windows Server 2008 R2 and everything there seems fine. If I connect a device with a static address (e.g. 172.16.202.10), it will connect. Stuck on what to do :(

  • How do I turn off WLAN automatically when LAN is connected?

    - by derroman
    I use my Thinkpad laptop with a docking station. The docking station is connected to my router via LAN. When I walk around the house I use my laptop with WLAN. Is it possible (and how) to manage these devices with a script or something to work like this: If a LAN-Connection is up, the OS should turn off Wifi and if LAN-Connection gets lost (undocking) Wifi should turn on automatically. I use Ubuntu 11.04 64bit with Gnome 2. The system works on an Lenovo ThinkPad R500 with. WLAN-Device: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] LAN-Device: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02) Any help would be appreciated. Thanks.

  • Programmatically setup a PEAP connection in Windows Mobile

    - by tomlog
    I have been working on this for a few days and this is doing my head in: Our application is built using the .NET Compact Framework 2.0 and running on Windows Mobile 5 & 6 devices. We can set the WLAN connection of the device programmatically using the Wireless Zero Config functions (described here: msdn.microsoft.com/en-us/library/ms894771.aspx), most notably the WZCSetInterface function which we pinvoke from our application. This works fine for WEP and WPA-PSK connections. In a recent effort to add support for WPA2 networks we decided to modify the code. We have successfully added support for WPA2 which uses a certificate for the 802.1x authentication by setting the correct registry settings before calling WZCSetInterface. Now we want to do the same for WPA2 using PEAP (MS-CHAPv2) authentication. When manually creating such a connection in Windows Mobile the user will be prompted to enter the domain/user/password details. In our application we will have those details stored locally and want to do this all programmatically without any user intervention. So I thought going along the same route as the certificate authentication, setting the correct registry entries before calling WZCSetInterface. The registry settings we set are: \HKCU\Comm\EAP\Config\[ssid name] Enable8021x = 1 (DWORD) LastAuthSuccessful = 1 (DWORD) EapTypeId = 25 (DWORD) Identity = "domain\username" (string) Password = binary blob containing the password that is encrypted using the CryptProtectData function (described here: msdn.microsoft.com/en-us/library/ms938309.aspx) But when these settings are set and I call WZCSetInterface with the correct parameters, it still prompts me with the User Logon dialog asking for the domain/username/password. Has anyone got an idea what I need to do to prevent the password dialog from appearing and connect straight away with the settings stored in the registry?

  • Tiny linux box with 2xGbLAN, WLAN and 10MB/s AES throughput?

    - by Nakedible
    I'd like to find a small linux box with the following specifications: Small (mini-ITX size is OK) Fanless Runs Debian At least two gigabit network interfaces WLAN that supports "host ap" with hostapd + mac80211 in AP mode Can encrypt AES at least 10 megabytes per second Total cost $300 or less Solutions from multiple parts also accepted - I can buy an external network card etc. and build the box myself if the components are available. If you don't know about the "host ap" thing, just suggest your solution, I'll find out if I can get that resolved. If I can't get all that, I can possibly skip the "runs Debian" part, and I can definitely skip the hostapd part if the box can be a wireless access point with multiple ESSIDs out of the box. Something like Asus RT-N16 is close - doesn't run Debian easily, and probably doesn't encrypt AES fast enough. Something like Zotac ZBOX HD-ID11 is also close - no idea which WLAN card it has and it lacks second gigabit interface, but otherwise nice.

  • Bridging: Loosing WLAN network connection with 4addr on option - Why?

    - by WitchCraft
    Question: For use with my Xen VM, I need to create a virtual network interface (vif) that is bridged to wlan0. If in /etc/network/interfaces I add auto xenbr0 iface xenbr0 inet dhcp And then later do brctl addif xenbr0 wlan0 I get this error message. can't add wlan0 to bridge xenbr0: Operation not supported I found out that Linux won't let you bridge a wireless interface in managed mode at all unless you enable the 4addr option (needed to recompile iw): iw dev wlan0 set 4addr on Afterwards brctl addif xenbr0 wlan0 works, and brctl show shows xenbr0 as bridged to wlan0. Unfortunately, as soon as I execute iw dev wlan0 set 4addr on my entire network connection is gone (no connection). As soon as then I execute iw dev wlan0 set 4addr off I reconnect and it works again. If I re-execute 4addr on, it breaks again, if I execute 4addr off, it works again. Unfortunately, I can't just turn 4addr on, activate the bridge and then turn it back off (error: device not ready). Does anybody know why I loose my connection ?

  • Upgrade AirPort on Macs to support Snow Leopard's Wake on Wireless/WLAN?

    - by wojo
    Snow Leopard now supports Wake on WLAN, but not all hardware supports this. For example, my Octo Mac Pro from early 2008 has an AirPort card, but it does not support this. Nor does my 2007 2.33GHz MacBook Pro. For reference to what is needed, look at http://www.macrumors.com/2009/08/28/a-closer-look-at-snow-leopards-wake-on-demand-feature/ which includes a screenshot of what the System Profiler should show. It's pretty hard to find Apple parts, but is it possible to put newer cards into these machines to have them support Wake on Wireless?

  • How to send a popup message to unknow computer connected to my WLAN?

    - by Leandro
    Is there any way to send a popup message from a Linux systen to a "random" laptop/tablet/mobile linked to my Wireless network ? For example, if I let my WLAN open and I see a not recognized computer connected to it, is there anyway to send to that device a message ? On the other hand, if I am connected to someone else open network and they may or may not be aware that their network is open, can I send them a message warning that I am accessing their network? Probably for a completely "random" device the answer should be no. But if we restrict to laptops with Win7 or Linux SO is there any service running by default on such systems that allows one to send such popup messages ? PS: I have no practical motivation for this question. This is only a curiosity.

  • My Laptop (HP/Compaq 2510p) running ubuntu 10.04 LTS keeps losing the WLAN connection.

    - by Ernelli
    I am using Wicd and can successfully connect to my ADSL router (Thomson TG 787) using WPA PSK. But with regular interval I lose the ability to connect to Internet. I can ping the GW and can actually ping servers on the Internet but not connect to them using HTTP (Tested with both Firefox and wget). I would suspect the router unless for the fact that the problem does not show up when running Windows XP on the same computer and also, when the problem arises, a simple disconnect/connect in Wicd solves the problem, which does not involve the router (Except for the DHCP request). I have searched Ubuntu forums without luck, most problems described relate to specific network drivers or other problems. Does anyone have the same experience with Linux/Ubuntu and WLAN?

  • Possible Solution for Setting up a Linux VPN Server to Encrypt WLAN Traffic of Macs and iPhones on

    - by GorillaPatch
    I would like to set up a VPN server on debian linux to encrypt wireless traffic coming from my Mac or iOS device. I would like to use a certificate-based solution. Setting up a PKI infrastructure and managing certificates is OK for me. 1. Which server to pick? By looking through the internet and here on stackoverflow I found the following possible solutions: strongSwan IPSec and racoon Which solution is feasible for a linode running debian squeeze? 2. How to configure the network? If I understood correctly a VPN has a virtual network interface as an endpoint on the server side. Naively I would think that I need a DHCP server running on the server to assign a dynamic private IP (like of the class C network 192.168.xxx.xxx) to the connecting clients. Next I think I would need to set up masquerading to NAT the incoming VPN traffic to the real interface directly connected to the internet. Is this the right way to go? Do you have any configuration examples? I often saw VPN configurations used to connect to your home network, but that is not what I am looking for. I have a server up in the internet and want to use it as a proxy to encrypt traffic in insecure network environments like public WLANs.

  • Android - Connectivity Questions

    - by Donal Rafferty
    I have a couple of questions about connectivity on Android, if anyone has any insight it would be great. What is the default when an application wants to wirelessly connect? Is it wlan? And if wlan is switched off or there is no access points around is it 3g or gprs? Is a device always ip connected? Or when its disabled from wlan or 3g does it lose its ip address? Is an application, for example the browser only ever connected to one ip address? Or can it be connected to multiple addresses for each radio such as gprs or wifi (wlan)? Can an application decide which connection to open a socket to? For example can I create an application and decide whether to connect the socket to the wlan or gprs? Or does the OS decide? Finally how do native applications handle connectivity? In the same manner?

  • Route all wlan0 traffic over tun0

    - by Tuinslak
    I'm looking for a way to route all wlan0 traffic (tcp and udp) over tun0 (openvpn). However, all other traffic originating from the device itself should not be routed through tun0. I'm guessing this could be realized using iptables or route, but none of my options seem to work. # route add -net 0.0.0.0 gw 172.27.0.1 dev wlan0 SIOCADDRT: No such process Info: This is because the VPN server is not redundant, and wlan users are not really important. However, all services running on the device are fairly important and having a VPN virtual machine with no SLA on it is just a bad idea. Trying to minimize the odds of something going wrong. So setting the VPN server as default gateway is not really an option. I also want all wlan0 user to use the VPN server's IP address as external IP. Edit with the script provided: root@ft-genesi-xxx ~ # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.27.0.17 0.0.0.0 255.255.255.255 UH 0 0 0 tun0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.13.37.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0 172.27.0.0 172.27.0.17 255.255.192.0 UG 0 0 0 tun0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 root@ft-genesi-xxx ~ # ./test.sh RTNETLINK answers: No such process root@ft-genesi-xxx ~ # cat test.sh #!/bin/sh IP=/sbin/ip # replace with the range of your wlan network, or use fwmark instead ${IP} rule add from 10.13.37.0/24 table from-wlan ${IP} route add default dev tun0 via 127.72.0.1 table from-wlan ${IP} route add 10.13.37.0/24 dev wlan0 table from-wlan

  • Connect Ralink RT2571 to new PC

    - by tuelsch
    I bought a new PC with the AsRock Z77 Extreme 4m motherboard, since this has no WLAN, I extracted the WLAN card from my old PC, a Ralink RT 2571 WF, an connected it to the new board. I downloaded the driver from http://www.ralinktech.com/en/04_support/support.php?sn=500 (the RT257x USB one) and installed it. In the device manager, an unknown device shows up, but if I tell it to search its driver, it does not find it (searching in the whole C partition). The Ralink Diagnostic Test says that the WLAN Card is disabled. I'm using Windows 7 64bit professional. Can anyone suggest me a solution to get my WLAN running?

  • Linux VLAN Bridge

    - by raspi
    I have home network with VLANs, one for LAN, one for WLAN and one for internet. I'd like to use bridging so that instead of configuring these same VLANs to every machine, they had own VLAN ID and bridges were LAN, WLAN and internet. I've tried it but for some reason keep-alive/ttl seems to get broken because SSH sessions etc suddenly disconnects. We have this same setup working in workplace for 4+ years with 100+ customers but it's custom firewall/router hardware so accessing it is impossible. I know that it runs Linux. So what is Debian/Ubuntu default network settings doing wrong or is it just NIC driver/hw problem? I've tried to mess araund with ttl etc settings without any luck. The bad stuff is happening in the bridge because current VLAN-only setup works fine. interfaces: auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 allow-hotplug eth1 iface eth0 inet static iface eth1 inet static auto vlan111 auto vlan222 auto vlan333 auto vlan444 auto br0 auto br1 auto br2 # LAN iface vlan111 inet static vlan_raw_device eth0 # WLAN iface vlan222 inet static vlan_raw_device eth0 # ADSL Modem iface vlan333 inet static vlan_raw_device eth1 # Internet iface vlan444 inet static vlan_raw_device eth0 # LAN bridge iface br0 inet static address 192.168.0.1 netmask 255.255.255.0 bridge_ports eth0.111 bridge_stp on # Internet bridge iface br1 inet static address x.x.x.x netmask x.x.x.x gateway x.x.x.x bridge_ports eth1.333 eth0.444 bridge_stp on post-up iptables -t nat -A POSTROUTING -o br1 -j MASQUERADE pre-down iptables -t nat -D POSTROUTING -o br1 -j MASQUERADE # WLAN bridge iface br2 inet static address 192.168.1.1 netmask 255.255.255.0 bridge_ports eth0.222 bridge_stp on Sysctl: net.ipv4.conf.default.forwarding=1
