How to check if DHCP Server is running in a network

[Raghavendra]

Hi,

  My requirement is to check whether dhcp server is running in a network, where my device is connected? its not on the same device but on a different device in some network.

        one solution for this would be 

        to check the existence of dhcpd.pid,  this would be a file in my case it is located in /var/run. you can always do find/locate to find the path.

        if you can find the file dhcpd.pid, then dhcpd would be running otherwise not.

        Thanks,
        Vasavi.

          Hi,

           I have a requirement where in I have to check after every 3 minutes whether some dhcp server is enabled/running in the network. Enabling dhcp client after every 3 minutes is a big over head, so I would like to first search/look if any dhcp server running in a network, if so i will enable dhcp client to get IP, else I will once again look for dhcp server after 3 minutes.

          Thanx in Advance.
