Hey guys,

I've never really messed around with Routers via SSH, I'm guessing it's a form of embedded linux (I'm sure there will be many different types of systems out there on various routers, but I'm generalising here)

I was wondering if anyone had any ideas on what you can actually DO in here, it seems that most systems are read only (yet I assume you would be able to reflash them via this interface or you wouldn't be able to configure your router here) - I have heard of a program to install and it flips images at this level, packet sniffers spring to mind etc

I guess to lay it out - what I'm looking for here is

a) What can be done with this - applications to install etc (there won't be much space - from what I've seen most home broadband routers seem to have about 16 megs total, with only 500kb or so free
b) How can you go around doing it - like I said, from what I've seen the file system was read only - can you change this?

I have a little bit of knowledge when it comes to Linux, not much but I have at least used it before :P

Thanks guys!
