I am trying to ping a list of machines, do an nslookup on the ip addresses, then if hostname is same as original hostname, read from another txt file to output possible location of hostname.
this is my hh.bat script:
@echo Off
@cls
if '%1'=='' GOTO Syntax
echo Running Script and Saving Results to Results.CSV
echo Script Run %date% %time% >> Results.csv
for /F %%i in (%1) do Call :StartPing %%i
goto :EOF
:StartPing
PING %1 -n 1| FIND /i "TTL" > nul && goto Success
PING %1 -n 1| FIND /i "timed" > nul && goto Timedout
PING %1 -n 1 -w 400 | FIND /i "TTL" > nul || goto ErrorMsg
:Success
for /F "tokens=3" %%a in ('ping %1 ^| find /i "TTL"') do set Address=%%a
for /F "tokens=2" %%a in ('ping -a %Address::=% ^| find /i "pinging"') do set HostName=%%a
set IPAddress=%Address::=%
nslookup %IPAddress% | find /i "Name" do set nsNAME=
echo %1, %IPAddress%,%Hostname%
echo %1, %IPAddress%,%Hostname% >> Results.csv
goto :EOF
:Timedout
Echo %1, Request timed out.
Echo %1, Request timed out. >> Results.csv
:ErrorMsg
Echo %1, Ping request could not find host.
Echo %1, Ping request could not find host. >> Results.csv
goto :EOF
:Syntax
echo . . .
goto :EOF
:EOF
echo this is the END OF FILE
pause
and this is my host.txt file
Computer1
and this is the list of locations - home.txt
ipaddress - 2G
either ip or hostname... i don't know
hostname - 2D
i am struggeling to do the NSLookup part, and have no idea how to read from the home.txt once nslookup is successfull and echo on the location line.
any suggestions or ideas?

These snippets may help you (untested):
for /f "tokens=2" %%a in ('nslookup %IPAddress% ^| find /i "Name: " ') do set "nsNAME=%%a"
echo "%nsname%"
pause
for /f "usebackq delims=" %%a in ("home.txt") do (
echo "%%a"
)
pause
-
thank you for the reply. Looks perfect.
however, upon testing... the second the script hits the NSLOOKUP part, it creates 1700+ processes, doing the nslookup %IPAddress% ^| find /i "Name: " part.
I am running this script hh.bat host.bat

If you are getting 1700 processes running then you have a loop that is neverending - quite possibly because you called your batch file nslookup or you have another problem in your code. Post it here as you have changed it for people to look at.

File is called hh.bat
and i run it in cmd like hh.bat host.bat.
everything works fine without the nslookup part. once nslookup lines are active and uncommented and the script hits it, processes goes up from 390, 1700 or even 3500 sometimes.

There is a system command called hh so pick another name, but that isn't the issue.
Do you have a set of computer names in host.bat or IP addresses?
When using IP addresses it works, but using computer names it fails because the ping command doesn't include "TTL=" even though it is successful - which is a new behaviour on me. Tested with the localhost in Windows 8.1 and it uses IPV6 in the ping screen display.
Your code is missing a goto :EOF here and there and FWIW the :EOF label is internal to CMD and isn't needed in the batch script.
Try this code - using a simple home.txt file with
a b reading
c d file
and in your hosts.bat just include a few computer names, and try it with a few IP addresses as a test too.
Show us what it displays on the console if it still misbehaves.
Make sure there are no ping.bat or nslookup.bat in the current directory or on the path. I didn't notice a problem with extra processes.

Interesting. Thank you for the feedback and updates.
will test in the morning once i am back at the office again.
i'll rename the main hh script to something very random.
and apologies, there isn't any host.bat, it should have been host.txt...
hh.bat -> to be renamed to qwe.bat = contains main script
host.txt -> just a list of computer names
home.txt -> ip addresses - office location (eg. 172.16.1.55 - Reception)
Try this code - using a simple home.txt file with
a b reading
c d file
-
Excellent! 8)
script is working like a charm.
can now even put a if state to tell me if hostname is bad or good, as well as location.
Just excellent stuff!
Thanks a million!
-
one other issue I have picked up is when the script reaches the get location part...
for /f "usebackq tokens=3" %%a in ("home.txt") do (
echo Your machine is located at "%%a"
)
cls
echo "%%a"
it echos out every line in the home.txt, instead of only looking for the specified IP address in home.txt and echo only the location
home.txt looks like this...
172.16.4.15 - Reception
172.16.5.155 - Server Room
It should only echo either the entire line where it finds the IP or only the Reception or Server Room part.
any suggestions on this?
-
Instead of this:
:: Get Location of machine
:: cls
:: replace tokens=3 with delims= to get the whole line
for /f "usebackq tokens=3" %%a in ("home.txt") do (
echo "%%a"
)
Try this: (untested)
:: Get Location of machine
:: cls
findstr /b/e "%~1" "home.txt"
-
Thank you for the reply.
i have added your suggested code as suggested, but how do i echo from that findstr command?
or how can i put the result of findstr in some variable?
-
It already echos it to the console, and you can get the information into a log file like this, if that is what you want to do.
findstr /b/e "%~1" "home.txt" >>"file.log"
-
when i put it just as is then my command line tells me
FINDSTR: // ignored
that could be because i have 2 hostnames in host.txt.
however, when removing 1 hostname from host.txt it does not echo anything out.
-
Test it with the extra lines below and tell me what was echoed when the error appears on the screen.
It seems like the %~1 term has slashes in it.
echo "%~1"
findstr /b/e "%~1" "home.txt" >>"file.log"
pause
-
it only echos out the hostname found in host.txt
Computer1, 172.16.4.115,computer1.localdomain.net
HOSTNAME is GOOD
"Computer1"
FINDSTR: // ignored
Press any key to continue . . .
-
Use this instead.
findstr /i /c:"%~1" "home.txt" >>"file.log"
-
for some reason that still returns nothing and file.log is empty.
the closest to working that i had so far was...
:: Get Location of machine
:: replace tokens=3 with delims= to get the whole line
for /f "usebackq tokens=3" %%a in ("home.txt") do (
echo "%%a"
)
however, this echos out everything in home.txt. and not only the location of specified IP or ONLY the line where the IP address is found.
-
Only you know what is in the home.txt file and in the %~1 term.
Run this yourself to prove that it works.
@echo off
echo Computer1 - basement>home.txt
echo Computer2 - treehouse>>home.txt
findstr /i /c:"Computer1" "home.txt" >>"file.log"
-
ok, don't know what i did wrong or where it went wrong...
commented every step, echo'd what is happening.
cls the screen after each step and explaining the next step...
now it works like a charm again, and tells me only the IP and location of the hostname i originally searched for.
is there and way to only show the treehouse part after the Computer1 -
i have removed the >> file.log and now it echos out onscreen :)
-
Given this home.txt
172.16.4.15 - Reception
172.16.5.155 - Server Room
then this should work.
for /f "tokens=1,* delims=- " %%a in ('findstr /i /c:"%~1" "home.txt" ') do echo %%b
As mentioned in an earlier post, if your network is IPV6 capable then the ping test can fail and skip servers.
-
nah its fine. its really fine if it echos out the ip as well as the - server room part from home.txt
when changed to your latest suggestion it again echos out nothing.
i believe very strongly that the network is not ipv6 enabled. however, ipv6 dhcp seems to be working.
but everything and all systems still work on the ipv4 addresses.
thanks again.
i am happy with findstr /i /c:"%IPAddress%" "home.txt"
-
Use this as home.txt which is what you said the format of the file was:
172.16.4.15 - Reception
172.16.5.155 - Server Room
and run this as: myfile.bat 172.16.4.15 to prove to yourself that it works. I did change the last %%a to %%b
@echo off
for /f "tokens=1,* delims=- " %%a in ('findstr /i /c:"%~1" "home.txt" ') do echo %%b
pause
-
if i could...
i would give you a medal 8)
Working as hoped it should work.
just had to add the %IPAddress% variable in the findstr line to allow it to follow the rest of the script.
for /f "tokens=1,* delims=- " %%a in ('findstr /i /c:"%IPAddress%" "home.txt" ') do echo %%bthank you.
