A Mad Min: 2012

So, I have both wired and wireless available and want certain traffic to flow through specific interfaces. The wired interface will carry the general traffic and the wireless will carry traffic only for specific private subnets.

Assume that the wireless has a gateway of 10.1.12.1 and I want all 10.0.0.0 traffic to flow thru that interface. Also suppose I want a large portion of the 192.168.0.0 range to flow thru the same interface. However, the IP address associated with the wireless interface will change via DHCP whenever it comes online.

The following batch file will setup a route for these two ranges to flow through the IP address associated with the wireless interface but only if the wireless gateway is a specific value. All other traffic will flow by default through the wired interface. Because the route tables will route the more specific traffic before the more general, I can have a local wired subnet (/24 CIDR) within either of the two 10.x.x.x/8 or 192.168.x.x/16 CIDR ranges and the general internet traffic will still flow through the wired interface.


@echo off  
 set WANGW=10.1.12.1  
 route print|find "%WANGW%">%temp%\WANIP.txt  
 for /f "tokens=4" %%i in (%temp%\WANIP.txt) do set WANIP=%%i  
 for /f "tokens=3" %%i in (%temp%\WANIP.txt) do set WANGW_FOUND=%%i  
 if %WANGW% == %WANGW_FOUND% (  
      route add 10.0.0.0/8 %WANIP%  
      route add 192.168.0.0/16 %WANIP%  
 )  
 del %temp%\WANIP.txt  
 set WANGW=  
 set WANGW_FOUND=

The following XML file can be imported as an automated task to run the route add batch file above when the wireless adapter comes online. Change the highlighted items as appropriate:

Remote CMD reset spooler – you need to have administrative privileges on the remote computer. The script can be used to restart the spooler on remote computer systems.

sc \\computername query spooler | find /I “STATE” | find /I “stopped”
if “%ERRORLEVEL%”==”1″ (sc \\computername stop spooler) ELSE GOTO NEXT

REM the Computer Name can be replaced by the computer’s IP address.
REM So the first command is querying the spooler and pipes the information to
REM second command to find the state, which is piping the information to the IF statement
REM the IF statement will make the decision what to do and pass the next execution to display on the screen the next message after @echo

@echo The Spooler is stopped Mapping the Jobs folder to delete the temp files

REM The next line maps a network folder because Command Line doesn’t understand UNC paths
REM Then you need to delete the jobs, which can be deleted easily since we made sure the print Spooler is not started.

net use x: \\computername\C$\windows\system32\spool\printers

REM After mapping the network drive, we are accessing it in the next line.

REM now we are able to execute the deletion of the spooled files with “del /q *.*”.
del /q *.*

REM Un-mapping the network drive “net use /delete x:” Then starting the Print Spooler
net use /delete x:
sc \\computername start spooler

REM Querring the spooler to see if its running. But here the Window might exit.

sc \\computername query spooler | find /I “STATE” | if /I “%STATE%”==”RUNNING” @echo Spooler has been started
