Remote Administration Using the TNADMIN Command with the -S, -K, or -M Parameter Does Not Work (322644)


The information in this article applies to:

  • Microsoft Windows Services for UNIX 2.0
  • Microsoft Windows Services for UNIX 3.0
This article was previously published under Q322644

SYMPTOMS

If you are using Windows Services for UNIX 2.0, and you use the tnadmin command with either the -s, the -k, or the -m parameter to remotely administer a Telnet server that is running Windows Services for UNIX 3.0, the command may not work. Alternatively, this command may not work if you are using Windows Services for UNIX 3.0 to administer a Telnet server that is running Windows Services for UNIX 2.0 or if you are using Windows Services for UNIX 2.0 to administer a Telnet server that is running Windows Services for UNIX 2.0.

CAUSE

This problem occurs because of changes to Telnet Server that occur if you apply the Q301514 hotfix that is described in the following Microsoft Knowledge Base article:

301514 Memory Leak in Telnet Server

RESOLUTION

To resolve this issue, apply the Q301514 hotfix that is described in the preceding section to all computers that are running Windows Services for UNIX 2.0.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION

The usage requirements for the following tnadmin command parameters have changed:
  • -s: List sessions
  • -k: Kill sessions
  • -m: Send message
The Q301514 hotfix includes security fixes that affect how these parameters are used. To use these parameters, you must be an administrator on the remote computer. If you use a parameter other than the parameters that are described in this section with the tnadmin command, you can pass credentials on the command line; however, the parameters that are described in this section do not allow you to pass credentials because of security limitations.

Operational Functionality
