Detect LAN Connection - wireless LAN card

Author	Message
Hari #1 / 5	Detect LAN Connection - wireless LAN card Hi I need to write a program that runs on a system having a wireless LAN card. Whenever this system it gets into the LAN, I have to run a process on this machine and then download a few files from the server. My question is - how do I know when the system has gotten connected to the LAN? Thanks in advance Hari

Chris Jone #2 / 5	Detect LAN Connection - wireless LAN card Try pinging a machine on the network. If you can successfully reach the machine, the machine is on the network.

hari #3 / 5	Detect LAN Connection - wireless LAN card Hi Chris Thanks for the response. But the problem I have is that this machine with the wireless LAN can enter into various LAN envirnoments. There will be many private LAN envirnoments. New small LAN envirnoments can be added / removed without prior intimation to this mobile system. Since it is not possible to know which private LAN the machine is in, I will not be able to ping (or is it possible...? Please tell me if it is) Regards Hari Quote: >-----Original Message----- >Try pinging a machine on the network.

Wauters Kri #4 / 5	Detect LAN Connection - wireless LAN card Check for the local IP address. if the IP = 127.0.0.1, then you are not connected, if the IP returns something else, you are connected.

David Klei #5 / 5	Detect LAN Connection - wireless LAN card well, this only works if there is an active dhcp-server on that network. i doubt that though, since he wrote that the the machine with the wireless card will connect to different private networks, which by default don't have dhcp-servers configured ... greets Wauters Kris schrieb: Quote: > Check for the local IP address. > if the IP = 127.0.0.1, then you are not connected, > if the IP returns something else, you are connected. > Bye, > Kris >>Hi >>I need to write a program that runs on a system having a >>wireless LAN card.
