My serviced office provides internet via a single ethernet cable (internet via lan). I wish to share this to multiple devices both wirelessly and over ethernet.
The office has given me specific IP, subnet, primary+secondary DNS details to access the internet over the ethernet cable.
What type of device do I need so that I can share this ethernet-internet connection to my own devices?
Just a simple router with wireless capabilities, no?

I have a raspberry pi 3 connected to my PC (Windows 7) via ethernet using DHCP server and VNC viewer and it works perfectly.
The pc is connected to a WIFI.
I want to access to internet from my raspberry pi, I tried the ICS sharing but it didn't work:
I shared the wifi connection:here
changed the ip address: here
after sharing the wifi connection, I am unable to access internet from both the pc and rasp even though they are in the same ip address.
On PC,On the Rasp
Can you please help me to find a solution?
Thank you.
You have to create a network bridge.
Select the two networks, right click and select bridge connections.
I'd use static IP address on your PI and your PC's ethernet
We have a shared PC in our LAB, connected to a Vector Network Analyzer (VNA). The PC communicates with the VNA through GPIB port, using Matlab functions. For my work, i need to acquire real-time data from the VNA into my own PC, which is few meters away from the VNA PC. I dont want to have wireless solutions due to the interference that might happen. I intend to buy a USB data transfer cable to connect the Matlab. But i couldn't find in google any similar idea to do so. I was wondering is such a solution practical? Does anybody has the same experience? And will be any problem regarding the drivers?
in USB bus systems there can only be one USB host all other devices are in USB device mode.in most cases the USB controllers of PCs are not capable of USB device mode, they all want to be USB host. in other bus systems like I2C this is called master-slave architecture
if you are lucky one of your PCs can be set to device mode and in this case this will work but your chances are very slim (because of the problem with the USB host and USB device mode)

a better solution would be to use ethernet
there are also modules in MATLAB for real-time communication over ethernet (Real-Time Transmit and Receive over Ethernet)
if your pcs have unused ethernet ports use an ethernet crossover cable (http://en.wikipedia.org/wiki/Ethernet_crossover_cable) and connect the pcs (i.e. http://www.ccm.net/faq/6340-connect-pcs-using-a-crossover-ethernet-cable)
else use an ethernet switch (or hub) to establish the ethernet communication between the pcs
beside MATLAB for communication you can use i.e. ssh or install a vnc server on one of the machines and remote-control it with a vnc client on the other,...
USB
with USB-to-ethernet adapters (ebay,...) you can use ethernet over usb when connecting the usb-to-ethernet adapters via a ethernet crossover cable
another possibility is to use two USB-to-serial adapters and connect them with a RS-232 crossover cable and then use RS-232 protocol for communication (putty,...)
Can I plug a cisco SPA303 ip phone directly into the ethernet port of a raspberry pi running raspbx?
I have got raspbx setup and running using a wifi dongle to connect to the router. The system works with the Cisco phone plugged into the router. However, the router is on the other-side of my house and ideally, as the raspbx is wifi, I would like to plug the phone directly into the pi and have it as one unit I can have anywhere in the house.
I have spent a painful amount of hours trying to set this up and I am sure there is a simple fix I am overlooking. Any ideas would be greatly appreciated.
Yes, you can. But you should setup static ip on phone or setup dhcpd server on RPi
Also some cisco phones have double ports(internal simpler switch inside). If so, you can connect one-by-one upto 8 phones.
There are several layers to take into consideration:
Link layer MDI/MDI-X detection of crossover/patch ethernet cable detection.
Static IP address for Raspberry Pi and a DHCP server for the IP phone
TFTP server to provisionize the IP phone
A peer in asterisk for the IP phone
how to list the network shared devices over LAN from IPad.Is it possible to list the shared devices programmatically using objective-c ?
How are you connecting the iPad to the network and what authentication is the network using? In general this would require a backend service to connect to the network and provide the network information over https to the iPad.
Using samba library we can access the LAN device files or using sockets with port of 445 can access the LAN machines.
I want to monitor the HTTP traffic sent/received from my iPhone. The iphone is connected to the Internet via my wifi router.
I want to capture packets from my windows 7 station.
Thanks for your help.
You have a few options here:
If your wireless router has a port mirroring or port spanning feature, turn it on and point it at your workstation's IP. Use Wireshark on your workstation to look at the packets arriving on the interface assigned to that IP.
If your workstation has a wireless card, get Connectify for Windows 7 (turns wireless card into Wifi Hotspot). Connect iPhone through Windows 7 wireless, and workstation through ethernet to the internet. Your workstation will effectively act as a router for your iPhone and you will be able to record iPhone's packets passing through it.
Get an ethernet hub (make sure it is not a switch, you won't see all packets on every interface with a switch), and connect your workstation, wifi router and internet to it.
Get a switch with port mirroring feature, configure port mirroring to forward a copy of all packets to your workstation.
Another option that I wish someone would have mentioned to me is pfSense. This is an operating system based on BSD made to serve as a firewall. Top of the line routers have, say 400 Mhz of processing speed, and unimpressive amounts of ram. The lowest-end computer you'll find these days has better specs than that, and of course, it's upgradeable. You don't have to bother with those terrible Cisco licenses (no DHCP with no license, 20 DHCP users at one license level, 100 users at an higher lever? Ludicrous), etc. Best of all, you have "root' access to the system, so you can run whatever you want on it (including wireshark, say)!!
Make sure you have two sufficiently fast ethernet cards. You'll set your wireless router to not do NAT (because pfSense will be doing that), then you can get to work setting up your VPN server, etc. without thinking about cisco licensing, etc.
