I my nick is daltanious78 and i have a question circa about linux commands and router, the question is:

the router is a pc that performs only the operations for which it was programmed, in some model of router you can install modified firmware based on Linux,to do this it is necessary that the router possesses enough space on the flash memory and RAM to start that version of firmware related additional modules.

The question I wanted to ask is, is there a command, a program, or some utility that allows you to see and to list all the hardware router and see if it is compatible with one of these firmware of which I have mentioned before?
if so what is this command, program or utility?

Thanks for all

If you are asking about the typical home commercial router like Netgear, D-Link or Linksys then I am not aware of any way to access that information. The dd-wrt website has an extensive list of models and hardware information. Maybe others have a better idea.

You may also find useful information at the tomato router website. (Tomato is an alternative to dd-wrt.)

I have one acquaintance--a sysadmin--who uses tomato as a matter of routine. For my simple home network, I've always stuck with the out-of-the-box router firmware.

well the short answer to the above question is the linux system itself
you did say this is a pc
commands like
ifconfig -a will show all the network adpters
route - show / manipulate the IP routing table

or

do you mean a router ?
do you have the router or will you be getting one
ether way hav a look at https://wiki.openwrt.org/toh/start
you will need an exact match with the model and firmware
or you will brick the router when you go th reflash it
