Hello Apparently no one fixed that bug in the last two years so I made another attempt :)
Attached you will find a much improved version of the script. Apart from fixing the two wishes you made it got some command line options, too: # ./dhcp-lease-list --help Prints active DHCP leases. Usage: ./dhcp-lease-list [options] --help shows this help --parsable machine readable output with full dates --last prints the last (even if end<now) for every MAC --all prints all entries i.e. more than one per MAC test2:~# ./dhcp-lease-list --all # MAC IP valid until manufactorer 08:00:27:0b:e2:b5 10.159.77.26 2008-07-11 01:30:20 CADMUS COMPUTER SYSTEMS 08:00:27:4d:d8:0d 10.159.77.27 2008-07-13 21:58:59 CADMUS COMPUTER SYSTEMS 08:00:27:4d:d8:0d 10.159.77.127 2008-07-13 11:58:59 CADMUS COMPUTER SYSTEMS test2:~# ./dhcp-lease-list --last # MAC IP valid until manufactorer 08:00:27:0b:e2:b5 10.159.77.26 2008-07-11 01:30:20 CADMUS COMPUTER SYSTEMS 08:00:27:4d:d8:0d 10.159.77.27 2008-07-13 21:58:59 CADMUS COMPUTER SYSTEMS test2:~# ./dhcp-lease-list # MAC IP valid until manufactorer 08:00:27:4d:d8:0d 10.159.77.27 2008-07-13 21:58:59 CADMUS COMPUTER SYSTEMS test2:~# ./dhcp-lease-list --parsable --last MAC 08:00:27:0b:e2:b5 IP 10.159.77.26 BEGIN 2008-07-11 01:20:20 END 2008-07-11 01:30:20 MANUFACTORER CADMUS COMPUTER SYSTEMS MAC 08:00:27:4d:d8:0d IP 10.159.77.27 BEGIN 2008-07-13 21:48:59 END 2008-07-13 21:58:59 MANUFACTORER CADMUS COMPUTER SYSTEMS The script and a man page are attached. bye, -christian- On 2008-01-14 Andrew Pollock wrote: > On Fri, Sep 29, 2006 at 03:16:54PM +0200, Christian Hammers wrote: > > Package: dhcp3-server > > Version: 3.0.1-2 > > Severity: wishlist > > Tags: patch > > > > Hello > > > > Please find attached a little script that generates the following output.
