Updated: November 14, 2007

Applies To: Windows Server 2008

yellow

Subsystem for UNIX-based Applications (SUA) Functionality is a measure of how the SUA send-and-receive utility, Psxss.exe, is functioning. When Psxss.exe is operating normally, SUA is able to accept user commands, and port applications over to Windows-based operating systems from UNIX-based operating systems.

Event Details

Product: Windows Subsystem for UNIX-based Applications
ID: 1025
Source: Microsoft-Windows-SUA-Psxss
Version: 6.0
Symbolic Name: PSX_BAD_SECURITY_FILE
Message: The security file was damaged, and has been recreated. This will cause existing device special files to be rejected; these files must be recreated. See the makedev -f command to restore default special files.

Resolve

Recreate device file

Subsystem for UNIX-based Applications has experienced a loss of functionality, and device files must be recreated.

Run the command /usr/sbin/makedev -f in a shell session to restore the default device files.

Verify

Verify that the Subsystem for UNIX-based Applications (SUA) Psxss.exe utility is functioning, first by viewing Psxss.exe in the Windows Task Manager, and then by using an SUA application that you have developed or are porting to Windows to transmit data over the network.

To verify that Psxss.exe is running:

  1. Open Windows Task Manager by pressing CTRL+ALT+DEL, and then clicking Task Manager.
  2. On the Processes tab, select the Show processes from all users check box.
  3. Verify that PSXSS.exe is running.

Next, use an application on which you are working in SUA, or that you are porting to Windows by using SUA, to send some data over the network. For example, attempt to use your application to modify files or documents in another location on the network. If PSXSS.exe is functioning properly, and is active in the list of processes in Task Manager, sending SUA application data over the network should succeed.
