Logon Script To Attach To A Server Based On IP Address 

Logon Script To Attach To A Server Based On IP Address

Info on both Kix and batch file commands to do things based on the IP address of the client.
Examples in case they get lost.
Kix:-
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;Establishes $location variable, determined by subnet
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
:IPCHECK
$address = @IPADDRESS0
$subnet = SubStr($address,9,3)
$subnet1 = SubStr($address,13,3)
Select
Case $subnet = "xxx" And $subnet1 >= "xxx" And $subnet1 <= "xxx"
$location = servername-1
"net use d: \\" & $location &"\" & @username &" /persistent"
Case (($subnet = "xxx" And $subnet1 >= "xxx" And $subnet1 <= "xxx") $location = servername2
"net use d: \\" & $location &"\" & @username & " /persistent"
EndSelect
or something to that effect...

Normal batch commands:-

@ECHO OFF
IF EXIST Z: NET USE Z: /DELETE > NUL
IPCONFIG | FIND "10.76.128." > NUL
IF ERRORLEVEL 1 GOTO NotInNet1
NET USE Z: \\server1\%username% > NUL
:NotInNet1
IPCONFIG | FIND "10.76.129." > NUL
IF ERRORLEVEL 1 GOTO NotInNet2
NET USE Z: \\server2\%username% > NUL
:NotInNet2

Thanks to bphilhower for the kix version and Witto for the batch commands.

www.centos.org - Forums - CentOS 5 - General Support - yum update three systems with only one download?:
"rsync --archive /var/cache/yum/ machine2:/var/cache/yum/"
Here's a simple way to use rsync to update the yum cache of machines from that of a previously updated machine prior to running yum update on the machine.
This can save up to a gig or more of download across 4 or more machines.

A good article from the boys at Red Hat on the many uses of the screen command.
The shared screen session for teaching other people is something I didn't know about, but I'm likely to use.
