NetMaster Web Portal shows Unix socket connection error

Products

• NetMaster Network Automation

Issue/Introduction

After spending some time away from the application,  I still seem to be getting this error . It might be that my systems are IPLing and the services are restarted.

Error showing in the Web Portal:

A Unix socket connection error was encountered; the socket is either closed
or already connected. (cause=Error reading 32 bytes(s) at offset 0. End of
Stream reached,rc=1)

I can get around it by going to /PARMS and updating the NMAPI parameter group, then actioning and saving it.

Environment

Netmaster Network Management for TCP/IP 12.2 and higher

Resolution

Review of the Netmaster activity log shows

N47H99 N47J06 SIGNON FAILED FOR USERID user123   - APPC LOCK/KEY MISMATCH. REQUESTING USERID NETMBSYS

Basically there is an APPC authorization mismatch between USERIDS, in this case USERID user123 (the user attempting to use the Web Portal) and the background userid NETMBSYS.

To rectify, do the following:

1.  =/uams 

2.  Select Option ===> l 

User ............... user123  

3.  Then either  'B'rowse or 'U'pdate. 

4.  On Page 2 you will see the APPC Authorizations. They should always be:

APPC Access Key .............. ALL  
APPC Access Lock ............. ALL  

5.  Verify and change that to match what you have defined for the NETMBSYS userid going through steps 1-4 for 'NETMBSYS'.

I would make sure that all of your USERIDS have the same values, best practice being

APPC Access Key .............. ALL  
APPC Access Lock ............. ALL
