Hi Guys,

I have recently installed Hostmon version 9.90 to monitor a device and execute certain batch files in windows shell using VBS to change configuration in the event of device failure.

I am using a windows 2003 standard R2 server and have noticed that the vbs script (called through a windows command shell via external program option) only works if HMon is running as a stand-alone application and not as a windows service. Have tried changing user credentials to admin but it hasnt helped.

I do not have any prior knowledge of scripting, so would like to make minimal changes to the script below:

Basic flow:
1. when device fails Hostmon generates a trap and runs a windows batch file which runs the command : telnet 192.168.x.x and then runs a VBS file..details below:

ftp -A -i -s:ftp.txt 192.168.161.6
sleep 20
:: Open a Telnet window
start telnet.exe 192.168.161.5
:: Run the script
cscript SendKeys1.vbs


2. I noticed that the vbs script only passes values when HS runs as an application..Script sendKeys1.vbs below:

set OBJECT=WScript.CreateObject("WScript.Shell")
WScript.sleep 5050
OBJECT.SendKeys "y{ENTER}"
WScript.sleep 3050
OBJECT.SendKeys "administrator{ENTER}"
WScript.sleep 2050
OBJECT.SendKeys "nmxxxxxxx{ENTER}"
WScript.sleep 2000
OBJECT.SendKeys " net stop ""mgxxxx"" {ENTER}"
WScript.sleep 2050
OBJECT.SendKeys " netsh interface ip set address name=""xx"" static 192.168.15.7 255.255.255.0 {ENTER}"
WScript.sleep 5050
OBJECT.SendKeys " netsh interface ip set address name=""xxxx"" static 192.168.161.7 255.255.255.0 192.168.161.254 1 {ENTER}"
WScript.sleep 5050
OBJECT.SendKeys " exit{ENTER}"
WScript.sleep 50
OBJECT.SendKeys " "


3. similar scripts are used to telnet and change ip addresses in multiple other devices.



Could you please verify whether this is an issue because I am executing a run command instead of exec in vb script? What changes would you recommend?

Regards,
Sid

First, I would recommend to specify full path to SendKeys1.vbs and, possibly, for ftp.exe, telnet.exe and cscript.exe.

The path has been added to the script. Although i didnt suspect that was the issue since the ftp and telnet were working...It still doesnt work...

Can you run a sample cscript through a batch file in your lab using hostmonitor to see if the vbs script can display text in a windows command prompt/notepad.

Yes, this will not work in Service mode.
However, if you'll start telnet inside VB script, telnet commands will be executed from HostMontor, running as Service.
Try the following:
1. Remove/comment the following line in your .BAT file:
start telnet.exe 192.168.161.5
2. Modify your VB script the following way (start telnet from VB script):
Code:
set OBJECT=WScript.CreateObject("WScript.Shell")
OBJECT.run "cmd.exe"
WScript.sleep 1050
OBJECT.SendKeys "telnet.exe 192.168.161.5{ENTER}"
WScript.sleep 5050
OBJECT.SendKeys "y{ENTER}"
WScript.sleep 3050
OBJECT.SendKeys "administrator{ENTER}"
WScript.sleep 2050
OBJECT.SendKeys "nmxxxxxxx{ENTER}"
...
