#58531 - 2001-08-24 05:23 PM Log dhcp leases using kixtart
Anonymous Anonymous Unregistered	I looked on microsoft knowledge base but didn't find any. Is there a way to log dhcp leases and put it on a separate files/directory? I would also like to have the date and time logged. I know you can use the @wksta @date, etc. on kix on this...I wonder how... If its not possible on kix, possibly resource kits? Thanks for the advice. -jvd [ 24 August 2001: Message edited by: jvd626 ]

Under Win2K, check key HKLM\CCS\Services\{NIC CARD ID}\Parameters\Tcpip, DHCPIPAddress Under WinNT check key HKLM\CCS\Services\{Nic Card}\Parameters\Tcpip, DHCPIPAddress You'll have to investigate further for Win9x.

Since KiXtart only runs when a user logs in, it is not a live dynamic solution. Since machines can renew their IP address inbetween logons, there is no "live" way for KiXtart to get that information for you. You might be able to query/read the Microsft database that stores this information, but then again you might corrupt it trying to read it in a live situation using remote methods.

Anonymous Anonymous Unregistered	Bryce, it doesn't matter which way I guess, as long as we know who has what. I think NTDOCs point makes sense, unless you can query the dhcp database somehow. How about if people try to renew their lease, say, when they type ipconfig /release ipconfig /renew? That couldn't be logged because the user is already logged in.

Bryce Bryce KiX Supporter Registered: 2000-02-29 Posts: 3167 Loc: Houston TX	well if all you want is a list of current DHCP leases.... use the NTresource kit tool DHCPCMD.EXE dhcpcmd <dhcpserver> enumclients <subnet> Bryce

Jeroen Jeroen Starting to like KiXtart Registered: 2001-08-16 Posts: 180 Loc: Netherlands	Another option (skipping the part about users using the /Renew and /Release options etc, since that's (I think) an unlikely event) is to use a program like Delayer.exe. Is can be run from commandline (login script) and can be used to execute a script after for instance 45 seconds or so. It has an option to be hidden from the user, so this might be an idea? This way, if the IP address is changed during logon, you'll get the IP address that's really being used... I don't have a URL for you, but if you can't find it, I can mail it to you if you like. _________________________ Regards, Jeroen. There are two ways to write error-free programs. Only the third one works.

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	bryce's info dhcpcmd.exe is good. I've used that little thingie and it defenetely shows correct info. it shows info when there are users that do not lock of their machines for months (like in our company) and thus can't be queried trhough logon script. it also shows current info on machines that are offline (which can't retrieved by remote registry call's). and still it can show info on reserved ip's that belong to examp. printers. or win9x machines that can't be accessed remotely. well, this is enough commercial allready, but with this tool you get directly current situation and directly in log format. _________________________ ! download KiXnet

Les Les KiX Master Registered: 2001-06-11 Posts: 12734 Loc: fortfrances.on.ca	I'm happy you found a utility to give you this information but... What value is there in knowing the lease info? I mean, it takes care of itself. I can think of no use for this information. Am I missing out on something? Had to ask... _________________________ Give a man a fish and he will be back for more.

Anonymous Anonymous Unregistered	LL, my boss wanted it so the leasing can be tracked down. I tried the dhcpcmd command but I'm not sure what its supposed to do. It just said: quote: DHCP server 5.5 Command Successfully completed. Is there anything else that needs to be done? What type of output does it give out? Thanks.

Les Les KiX Master Registered: 2001-06-11 Posts: 12734 Loc: fortfrances.on.ca	One of those bright ideas eh! Well, I figure you may have messed on one of the parameters. I tried: DHCPCMD.EXE 10.198.10.1 enumclients 10.198.0.0 on my LAN and it works. THe first IP is the address of my DHCP server and the second is my subnet. I still question the value of this info. When I want info on DHCP, I just run DHCPADMN.EXE on my WS. Still, it doesn't pay to argue with the guy that signs your paycheck. quote: DHCP Server version 4.1 1 10.198.50.1 999-51-197 09/06/2001 15:08:23 2 10.198.50.2 999-51-525 09/07/2001 10:02:53 3 10.198.50.3 ENI_SUPT 09/10/2001 07:34:14 4 10.198.50.5 999-51-554 09/10/2001 07:08:15 5 10.198.50.6 999-51-526 09/07/2001 08:06:34 6 10.198.50.8 999-51-555 09/10/2001 06:47:13 7 10.198.50.9 999-51-558 08/28/2001 08:39:05 8 10.198.50.12 FFENERGYSUPT 09/08/2001 11:41:24 9 10.198.50.13 999-51-407 09/10/2001 12:54:23 10 10.198.50.14 999-51-114 09/04/2001 08:01:43 [ 27 August 2001: Message edited by: LLigetfa ] _________________________ Give a man a fish and he will be back for more.

Les Les KiX Master Registered: 2001-06-11 Posts: 12734 Loc: fortfrances.on.ca	JVD, You need to use the DOS redirect > to the file of your choosing (hence the %comspec%). code: break on GO C: SHELL '%comspec% /c "C:\DHCPCMD.EXE" 10.198.10.1 enumclients 10.198.0.0 > C:\dhcp.txt' get $ Don't forget the single quote / double quote thingy if long names used. _________________________ Give a man a fish and he will be back for more.

Anonymous Anonymous Unregistered	cool, That worked, but I have another gripe How come it overrights the file instead of appending to it? Is there away so that it will append the file?

NTDOC NTDOC Administrator Registered: 2000-07-28 Posts: 11624 Loc: CA	I'm sorry JVD, The single > (redirect symbol) creates the file. The double >> (redirect symbol) appends to the file. SAMPLE: D:\>type fileone.txt hello D:\>echo hello again>>fileone.tx D:\>type fileone.txt hello hello again D:\> I hope this makes more since now.
