Python script to log dhcp leases
Posted by kiwinewt on 28 December, 2007Thought I would share this. It is called from DNSMasq in the dnsmasq.conf file: dhcp-script=/home/nate/logdhcp.py enjoy #!/usr/bin/env python import sys, string, array appendLine=1 if sys.argv[4]: f=open(‘/home/nate/dhcplog’, ‘r’) lineArray=f.readlines() for line in f: lineArray.append(line) for line in lineArray: if line == (string.join(sys.argv[1:])+”\n”): appendLine=0 f.close() if appendLine==1: f=open(‘/home/nate/dhcplog’, ‘a’) f.write(string.join(sys.argv[1:])+”\n”) f.close()
