http://serverfault.com – So I have an old computer functioning as an OpenBSD router for my home network. I had 3 network cards, one to wired home network, one to wireless network, and one to my modem. One day, pings magically stopped working. I login to the router with ssh over my wired network.. everything appears fine. dhclient is still getting an address from the modem and everything, but ping 8.8.8.8 doesn't work.. I double and triple checked my configuration for 2 days trying to figure out why. Finally, I decide to try putting in another network card. I put it in and change everything from fxp0 to rl2 and every (HowTos)

SSH in local wireless network 3 years 35 weeks ago

Hello everybody.

I've been using ssh recently to access a schools supercomputer, and that made me wonder if I could somehow do the same between my home machines.

I figure that if I get my machines (2) into a wired network I can make them 'see' each other (and interact through ssh), in fact I used to control one PC from another using VNC.

I recently switched over from Windows XP to Ubuntu 10.04. I am unable to connect to the network. Both wired and wireless are not working. I tried to connect by assigning the IP address manually and also by automatic DHCP assigning. It did not work. In the wired network when I access a site I get the message unable to connect to server. Pinging in wired network is 100% success.

i have 3 network cards , 1 Lan (wired) , 1 wireless network card & 1 is wireless usb

how do i ping from specific network card ?

& how do i use specific network card for specific application

example

i want to ping google from wlan1

example for specific application

i want to use firefox or transmission from wan1

Lan ip 192.168.0.2 > Working Properly

pin -I wlan1 googl

This is my network:

Dotted lines indicate wireless connections, solid lines indicate Ethernet connections.

I used two ASUS routers and Tomato to bridge my network.

I'm at a complete loss AND I have no idea what I'm doing.

Box and network via ethernet was fine. Moved the box with a new ethernet connection. Network crapped out.

All of a sudden my machine's wireless network is not connecting to my WiFi router.How can I figure out if its an issue with the WLAN card or if its withing the Ubuntu system settings ?Is there a command to check if the wireless is working ?

$ nm-tool

NetworkManager Tool

State: disconnected

Device: eth0 ---------------------------------------- Type: Wired Driver: e1000e

We have a small office network with DSL and a Netgear WNR-2000 wireless router acting as a DHCP server. There are nine devices connected to the router, wirelessly and wired. Whenever a Mac computer tries to connect, it's unsuccessful until we restart the router.

I have a computer with two network cards. From what I understand, I can use bonding to achieve greater throughput, so I followed this tutorial: https://help.ubuntu.com/community/UbuntuBonding

Till now, I've only managed to make the bonding work with mode 802.3ad. Any other mode just doesn't work.
