# Follow a file like tail -f.

    print("Log filename is: {}".format(logfilename))

    logfile = open(logfilename, "r")
    loglines = follow(logfile)

    for line in loglines:
        if "GET / " in line:
            ip = line.split(' ',1)[0]
            if CHECKIP(ip):
                print(line,)
                send_pushover(line)

This is for me only, if you need something like this ask me because I did not published iplib yet.

I could benefit from something this if you feel like sharing iplib
