Check remote windows logged-in user/lock status via BASH

Scenario:

We have Active Directory environment in our office. Clients OS are mixed starting from windows 2000/2003/2008 and Win7.
For some specific reasons/policy, our helpdesk staff is often required to inquire if the employee is working on his workstation or if his/her windows status is locked.

Solution:

Since I am using my Ubuntu box to manage most of the Active Directory functions using Webmin/BASH scripts, therefore I made a small bash script which queries for remote windows logged in user session and windows locked/unlocked status.

The bash script does the following …

• Check for remote PC PING Status, if ping fails, exit with error
• Get remote windows IP via NSLOOKUP using local DNS
• Current Logged-in user and their status
• Current status of windows either its locked/unlocked.
• TRIM the results and display according to our taste

the Script!

> root@linux:/temp# cat winuserstatus.sh

#!/bin/bash
# Script to check remote windwos status, like Loggedin + Windows Lock/Unlock status
# More functions can be added/removed as required.
# I attached this script to webmin for our Support dept.

echo "$1 not responding to ping request, probably system is not UP"
exit 1

Result:

When User is logged in and windows is LOCKED!

root@linux:/temp# /temp/winuserstatus.sh WORKSTAION-1

Remote PC = WORKSTAION-1
IP Details =
Address: 10.0.0.20
Address: 10.0.0.21

User Status = Logged in User found ... details as below ...
jahan.zaib console 13 Active 1+00:53 1/23/2017 1:57 PM
Windows Status = Windows is LOCKED

When User is logged in and windows is UN-LOCKED!

root@linux:/temp# /temp/winuserstatus.sh WORKSTAION-1

Remote PC = WORKSTAION-1
IP Details =

Address: 10.0.0.20

User Status = Logged in User found ... details as below ...
jahan.zaib console 13 Active 1+00:53 1/23/2017 1:57 PM
Windows Status = Windows is UN-LOCKED!

When User is NOT logged in and windows is LOCKED as well !

root@linux:/temp# /temp/winuserstatus.sh SERVER-2

Remote PC = SERVER-2
IP Details =

No User exists for *

User Status = No user is active

Gathering Stats from remote Windows via Linux Shell

Reference Post:

Following are few simple methods to query information for various instances like remote windows service status , performance monitor instance result with trimming , , execute commands on remote windows box , all being done from our beloved Linux boX 😉

I must admit that even after spending years in this field, I still feel myself very doodle, blockhead & light brain in almost every topic or subject I get confronted with ! STML plays an important role in my Deficiency  ‘_’    – 😉

Executing command on remote windows server, and get its result in output

$WINEXE --user=$DOMAIN/$ADMINID%$ADMINPASS //$SERVERIP "C:\TEMP\COMMAND.EXE -syntax-if-any"

Note: above command requires WINEXE tool (Linux tools to execute command on remote windows)

Querying Remote Windows Performance Monitor Instances

Example, we have Forefront TMG 2010 and we want to see its Cache Hit % from our linux box shell, so we can use following command (It was real hard to escape nested double quotes :O )

This is very very useful command and it took few hours for me to trim the required result for plotting graph.

winexe -U domain/admin%"password" //MYSERVER 'typeperf -sc 1 -si 1 "\\MYSERVER\Forefront TMG Web Proxy\Cache Hit Ratio (%)"'

and with bash script I used it like

root@linux:/temp# cat tmg-cachehit.sh

#!/bin/bash
# Script to query TMG cache HIT after trimming
#set -x
IP="10.0.0.1"
DOMAIN="MYDOMIN"
ID="ADMIN"
PASS="PASSWORD"
TMP_HOLDER="/tmp/$IP.cache.hit.txt"
winexe -U $DOMAIN/$ID%"$PASS" //$IP 'typeperf -sc 1 -si 1 "\\101.11.11.6\Forefront TMG Web Proxy\Cache Hit Ratio (%)"' > $TMP_HOLDER
RESULT=`cat $TMP_HOLDER | sed -n 3p | awk '{print $2}' | cut -d "," -f 2 | tr -d '"' | cut -f1 -d"."`
echo $RESULT
echo $RESULT

Check remote windows service status

Example if we want to query service status result of Lotus domino mail server  from our linux box …

root@linux:/temp# net rpc service status "Lotus Domino Server (DLotusDominodata)" -I 10.0.0.1 --user=DOMAIN/ADMINID%PASSWORD

RESULT:

Lotus Domino Server (DLotusDominodata) service is running.
Configuration details:
Controls Accepted = 0x5
Service Type = 0x110
Start Type = 0x2
Error Control = 0x0
Tag ID = 0x0
Executable Path = "X:\Lotus\nservice.exe" "=X:\Lotus\notes.ini" "-jc" "-c"
Load Order Group =
Dependencies = /
Start Name = LocalSystem
Display Name = Lotus Domino Server (DLotusDominodata)

I used all above commands in various script for alerts and mrtg graphing. you can use it to fulfill any customized requirements.
