Issue/Introduction

When trying to use the command-line Probe Utility to gather the status of a service this syntax was used:

pu -u administrator -p <password> /<domain>/<hub>/<robot>/net_connect test_service <host name> <port>  

but it is not showing the correct status as always returns status = 0

For example when trying to check if SMTP server is up (port 25)  on a server named my_smtp_server:

\Nimsoft\bin\pu.exe -u administrator -p <password> /my_domain/my_hub/my_robot/net_connect test_service my_smtp_server 25

hostname PDS_PCH 11 my_smtp_server

ip PDS_PCH 3 25

port PDS_I 2 0

status PDS_I 2 0

tused PDS_I 2 1

It returns a status = 0, even though the SMTP server is up and running, and listening on port 25.

Environment

• DX UIM 23.4.x
• net_connect 3.44 and previous

Cause

In the example above, 

\Nimsoft\bin\pu.exe -u administrator -p <password> /my_domain/my_hub/my_robot/net_connect test_service my_smtp_server  ##.##.##.## 25

the command shows that the ip receives an incorrect value, particularly the port.

hostname PDS_PCH 11 my_smtp_server

ip PDS_PCH 3 25

port PDS_I 2 0

status PDS_I 2 0

tused PDS_I 2 1

When running the callback test_service directly from the Probe Utility (IM or Admin Console), the IP can be left empty and it will still show the correct status:

Therefore, in the command line Probe Utility , pu.exe, the 3 first arguments are required, and they need to be entered in the same order.

pu -u administrator -p <password> /<domain>/<hub>/<robot>/net_connect test_service <host name> <IP> <port>  

 

Resolution

The 3 arguments, <host name>, <IP>, and <port>  must be supplied to run the callback test_service:

pu -u administrator -p <password> /<domain>/<hub>/<robot>/net_connect test_service <host name> <IP> <port>  

Then, the command above should be: 

\Nimsoft\bin\pu.exe -u administrator -p <my_password> /my_domain/my_hub/my_robot/net_connect test_service my_smtp_server ##.##.##.## 25

hostname PDS_PCH 11 my_smtp_server

ip PDS_PCH 3 ##.##.##.##

port PDS_I 2 25

status PDS_I 2 1

tused PDS_I 2 1

and this time the status is correct.
