Read from a list of hosts instead of querying whole domain

[bradit]

Hi Guys,

I've come across this batch script which essentially fires up psloggedon (by Symantec) for each IP on the domain and then neatly writes the output to a text file. I was wondering if there is a way to get it to read a lists of hosts from a text file instead so that I can query a set list of computers without having to do the whole domain.

From my understanding, currently it gets a list of everything on the domain using net view and then fires up PsLoggedOn for each and writes the results to an output file.

Here's the batch as it stands:

Code: Select all

@echo off
echo %date% >> C:\Output.txt
echo %time% >> C:\Output.txt
setlocal EnableDelayedExpansion
for /f "Tokens=1" %%c in ('net view /domain:"%USERDOMAIN%"^|Findstr /L /C:"\\"') do (
set isloggedon=0
for /f "Tokens=*" %%u in ('PsLoggedOn -L %%c^|find /i "%USERDOMAIN%\"') do (
set isloggedon=1
call :report %%c "%%u"
)
if !isloggedon!==0 call :report %%c nobody
)
endlocal
goto :EOF
:report
set work=%1
set comp=%work:~2%
set user=%2
set user=%user:"=%
call set user=%%user:*%USERDOMAIN%\=%%
@echo %comp% %user%
Echo %comp% , %user% >> C:\Output.txt

Any help would be much apprechiated, thanks.

Replace this line with the one below it - hostnames one per line in the file.

Code: Select all

for /f "Tokens=1" %%c in ('net view /domain:"%USERDOMAIN%"^|Findstr /L /C:"\\"') do (

Code: Select all

for /f "usebackq delims=" %%c in ("c:\folder\hostlist.txt") do (

Hi, thanks for the reply Foxidrive.

I've tried the change you suggested but it's just causing PsLoggedOn to hang with no output.

In the script I notice that it also tells PsLoggedOn to use %USERDOMAIN%, does this line also need to be changed to get it to read hosts from the text file?

Thanks,

Brad

Try this command with one of your hostnames and see if there is an error:

Code: Select all

PsLoggedOn -L hostname

%USERDOMAIN% is not set in your code and must be a system variable.

Also use this command at a cmd prompt to see what the output is as your hostnames may not be in the same format.

Code: Select all

net view /domain:"%USERDOMAIN%"|Findstr /L /C:"\\"

[bradit]

so,

Code: Select all

PsLoggedOn -L hostname

tells PsLoggedOn to search all machines on the domain for the hostname (treating it as a username).

The -L just tells it to show the local logon.

It seems to be the \\ which defines the host as a host.

here's the help file for PsLoggedOn:

Usage: psloggedon [- ] [-l] [-x] [\\computername | username]

- Displays the supported options and the units of measurement used for output values.

-l Shows only local logons instead of both local and network resource logons.

-x Don't show logon times.

\\computername Specifies the name of the computer for which to list logon information.

username If you specify a user name PsLoggedOn searches the network for computers to which that user is logged on. This is useful if you want to ensure that a particular user is not logged on when you are about to change their user profile configuration.

For the second part, net view gives a list of hostnames preceeded by \\

I've added // to the start of all of my hosts in hostlist.txt but now the PsLoggedOn is just giving a 'nobody' for each machine, but it is reading the hostlist. (if it can't find anyone logged on localy it will throw a 'nobody')

Trouble is, one of the machines is the one I'm using so it should be giving results.

Any ideas?

psloggedon (by Symantec)

Since when does Symantec own the the rights to that program.

[bradit]

Apologies, "Sysinternals".

[foxidrive]

I've added // to the start of all of my hosts in hostlist.txt

// or \\ ?

[bradit]

\\ sorry, busy day

[foxidrive]

For the second part, net view gives a list of hostnames preceeded by \\

With the /domain switch included?
The first token of the output of that is what the first loop is passing to the next part.

I don't have the network to test with so can't give advice without that info.

[bradit]

no jsut simply \\hostname

i.e

\\hostname1
\\hostname2
\\hostname3
\\hostname4
\\hostname5

[bradit]

The PsLoggedOn query that needs to be ran for each hostname in the hostlist is:

psloggedon -l \\hostname

Where hostname is the host from the input file (the input file currently contains hosts including the \\ )

[Squashman]

Code: Select all

FOR /F "delims=" %%G in (hostnames.txt) DO psloggedon -l %%G

[foxidrive]

It works fine here to give the value in the %%c variable Squashman. I don't know what the OP is doing.
