    Network Connection Test

    I am doing a network connection test program but I have no idea how to do the DHCP.

    For dns, gateway I am using ping command called by popen.
    For DHCP , i was told to to a dhcp discovery. Basically the DHCP client is already running in DHCP server.

    I read somewhere that ifdown, ifup command can be used to but have no idea how. Any idea ?

    I am making the program in C ( Linux 2.6 ).

    hello. I want to do a connection test on DHCP.

    I am trying to execute the following function:

    ifdown eth0
    ifup eth0

    then afterwards check if connection to DCHP server was successful. I tried it already but unfortunately the current internal ethernet on the board am working now is a bit defective, so it hangs up after i execute the down command.

    The next question is that, if the commands where successful, which file(s) tells me that the connection was successfully executed ?

    /etc/resolve.conf?



    Its a busybox , so commands and resources are very limited.

    The command : "udhcpc" might also be used but I am still trying to understand it now.
