hot plugging of ethernet
I have problem in hot plugging,
I have an embedded device board(ARM) and i have installed Linux on that board.. i booted , but later i realized i have not connected LAN cable to the board.. so when i connected the cable it gave message saying error in network connection .. to correct this error (to make device board to detect this LAN cable) i am required to reboot the board which is time consuming.. i would like to know is there any easier way so that my board detect the LAN cable even if i connect it after booting..please give me worried..i have heard about ifplugd but want other solutions because i do not want to install any new packages on the board..suggest me any change in udev rules or any such tweaks..

Welcome to LQ!

What's wrong with using the daemon 'ifplugd'?

This link and others are available from 'Slackware-Links'. More than just SlackwareŽ links!

We are using an embedded board and has got limited memory.. so i do not want to install any new packages..if i use ifplugd then it consumes the precious memory space of my board.. so i would like to know the solution by using udev or any other kernel rule change..

'ifplugd' and 'libdaemon' are just about 41KB. That tight?
