Have a list (text file) of DNS names. I need to resolve each one and record the IP address(es). I dont have access to the DNS server so cant grab the zone files.

Anyone fancy knocking together a script (Win2K Batch or Linux Shell) to nslookup each one and write the results to a file ?

Go-on, you know its more interesting than your own work...

You Can Do It In A Line Of Perl.

 

Ta David - YHM

 

You see I know it *should* be a line of perl - but buggered if I can ever get my head round perl enough to even start...

Go on prove it anyway

 

I had to cheat... couldnt get just an ip from nslookup without a bit more work.. and I have a hangover...

Save first script as test.vbs or similar..

Const ForReading = 1

Dim fso, theFile, retstring

Set fso = CreateObject("Scripting.FileSystemObject")
Set HostsFile = fso.OpenTextFile("c:\hosts.txt", ForReading, False)
Set WshShell = WScript.CreateObject("WScript.Shell")

Do While HostsFile.AtEndOfStream <> True
hostname = HostsFile.ReadLine
strCmdLine = "cmd /c c:\nsl1.bat " & hostname
WshShell.Run (strCmdLine)
Loop
HostsFile.Close


Save the following as c:\nsl1.bat

@ECHO OFF
for /f "tokens=2 delims=[]" %%i in ('ping %1') do Echo %1 %%i >>c:\output.txt

Then run test.vbs by either clicking on it or typing cscript test.vbs or wscript test.vbs

You should then get a file called output.txt with hostname ip

You also have mail...

Thanks David

Deano

p.s. chiark - you still havent proved your "one line" claim

 

he's too busy shopping in town...

Im not safe from scoobynet anywhere... nipped out for a walk (perv) around town..

David

 

I wasn't gonna bother, but since nobody else has

the file hostnames contains a newline delimited list of hostnames you want to resolve. Wont work on Win32.

perl -ne 'system("host", $_)' hostnames > output

Steve.

 

Hot weather, girls not wearing much and David's letching in town...

Cheers Steve, 10/10. Naturally, that was just what I was thinking. (ahem)

 

Hmm, I love the City in the summer. All those short skirted, high heeled women walking around *yum yum*
