Hi,
I want to develop an embedded web server using a NXP LPC2378 ARM. To develop it I want to buy the RL-ARM library and compiler but first I want to know if it supports the console command ARP -s command.
Sometimes if a customer don't remember the IP address is possible to associate a new IP address with the product MAC address with this ARP command and to web site access using this new IP address.
On the product brochure appears this protocol but I found some other servers with this protocol and this command don't operate.
Thanks and best regards.
I think you're misunderstanding what the ARP -s command actually does.
When you enter such a command on your PC (or whatever) it updates the ARP table contained on that PC. It does nothing directly to the remote device at all.
There are some devices that allow temporary IP addresses to be allocated by using a combination of ARP -s and telnet (e.g., Lantronix) and I've seen/implemented devices that use the combination of ARP -s and ping to do the same thing.
But, ARP -s on its own does nothing.
Dear Per and David,
Thanks for your replies. As you said David I want to use a combination of ARP -s and ping to create a temporary IP and web server access.
This combination operates with my Lantronix server and is a fast method to server access. If I don't remember the IP address and the subnet mask is the same as my computer I only has to create a temporary IP address with the ARP -s command and write it on my web browser to web site server access.
I will use other library if this command doesn’t operate.
