Disconnected clients still appear connected

When a PC client terminates a session--that is, disconnects a redirected drive--the associated process attempts to close the session in an orderly fashion. This includes removing the file name.number from the directory $TNHOME/TAS/tn/tndb. The name variable represents the machine name of the client PC, and number represents the UNIX ID number of the associated process.

If the client cannot remove this file, it exits without error, but when you check connection status or issue a tnwho or tninfo command, the client appears connected. Verify that totalnet owns the program srm, which does the actual removing of entries from the circuits directory, that srm has a mode of 4511, that totalnet owns the circuits directory, and that the circuits directory has a mode of 755.
