Solution 1940333.1 : E5-MS-45.0.0: Eagle Discovery failed with the error "Invalid machine credentials"

Applies to:

Oracle Communications EAGLE (Software) - Version E5-MS 45.0 and later
Tekelec

Symptoms

Issue encountered on E5-MS 45.0. EMS (Installation)

E5-MS installation encountered an error while configuring E5-MS for Eagle Discovery with ssh protocol enabled.

The Eagle discovery fails with the following E5-MS error window pop up:-

   "EAGLE <ip address> discovery failed!
Reason: Invalid Machine Credentials used for SSH port forwarding.
    Please report this issue to E5-MS Administrator.
    Please resolve this issue and retry."

Cause

Invalid Eagle login name and password entered in Eagle Discovery.

You may also hit the same error when you have incorrect machine credentials configured.
E5-MS stores the machine credentials (system username and password) in encrypted format on disk. These are needed for port forwarding mechanism while connecting to EAGLEs on ssh protocol.

Solution

Ensure the values entered in Eagle Discovery is valid for fields Login name, Password, IP Address & Protocol.
The recommendation is verify the Eagle is accessible with the same values from command line.

Note: Login name and password are case sensitive.

Ensure the telnet and ssh services are installed and up on the server.

If this does not resolve the issue, execute the following steps to update the machine credentials:-

1. Shutdown E5-MS services.
   # service e5msService stop

2. Execute E5MSConfigurationScript.sh script located in "/Tekelec/WebNMS/bin/"
   # sh E5MSConfigurationScript.sh

   Please enter E5-MS home path.(Absolute path till WebNMS directory):
   /Tekelec/WebNMS/
   Press 1 To update current system username and password in E5-MS
         2 To update current mysql root user's password in E5-MS
         3 To Exit
   Your Choice (1, 2 or 3): 1
   Enter Username (e.g. root): <if non-root username is entered here, you must execute step 3. >
   Enter Password: <enter password>
   Do you want to proceed with the entered username and password?(y/n): y
   Username and Password updated successfully in E5-MS.

3. This step is for non-root ONLY. Skip this step if "root" username is entered for "Enter Username (e.g root):" in step2.
   Edit the configuration file "server_conf.properties" located in "/Tekelec/WebNMS/conf/tekelec".
   Search for the line "LinuxMachinePrompt=\#" and replace the prompt sign "#" with "$".
