net$server.log generation

[RAVIKANTH_3]

when does a net$server.log file will be generated.
I have one decnet task to task communication. It is getting generated in one environment and not in other. When the box/node changes it is not getting generated.

What does that file signifies?
Will it be generated on all environments or any exemptions?

Many thanks
Ravi

Ravi,

if a new NETWORK process is being created for an incoming DECnet-connection is under a specific username and that user's login-directory can be written to by the created process, a NET$SERVER.LOG file should be created.

it could be that someone changed sys$system:net$server.com and modified the name of the log file. Or the directory.

Or the T2T reused a process of a just finished T2T (thus append to the file will be done).

Ravi,

Failure to create a log file is not considered fatal, and, obviously, can't be logged anywhere.

One way to block creation of new NET$SERVER.LOG files is to create one with version 32767

$ CREATE SYS$LOGIN:NET$SERVER.LOG;32767

Another possibility is the target account lacks write access to it's SYS$LOGIN directory, or delete access to an existing NET$SERVER.LOG.

By blocking log files you're potentially losing useful information. A better compromise to prevent disks being flooded is to set a version limit on the files.

To track where the files should be created, enable login alarms and watch where the processes are being logged in:

$ REPLY/ENABLE=SECURITY
$ SET AUDIT/ALARM/ENABLE=LOGIN=ALL

Here is a web search command that can be useful for these questions:

http://www.google.com/search?hl=en&q=net%24server.log+site%3Ah71000.www7.hp.com

The Google "site:" keyword targets the search to the specified web server host, and the server listed above is the location of most OpenVMS information and documentation.

becuase the log file generation is 32767, it is not generating any new files and it is blocking the new files generation.
So i have deleted this generation and logs got generated.
