Information Release

Release date 3^rd May 2007

TruePort amendments required when using Viaduct on Windows Vista

Throughout this Information release a carriage return is shown either by the symbol ¿ or <CR>. A space in a string is shown by the symbolÑ, all other spaces are purely cosmetic

Problem

There has been an issue reported that when Viaduct is installed on a Windows Vista machine and a connection is established to a Trueport port on a Linux machine, the network connection to the Linux machine is terminated for no apparent reason after a short period of time.

It has been found that the keepalive process for the TruePort post is effecting the Viaduct session and causing it to close down the connection.

Resolution

To resolve the problem you need to turn the keepalive off on all the trueport ports in the /etc/trueport/config.tp file and restart the trueport processes or system.

ANY AMENDMENTS TO THE TRUEPORT PORTS MUST BE DONE ON A QUIESCENT SYSTEM WITH ALL USER LOGGED OUT TO UNIX LOGIN AND A DATA BACKUP HAVING BEEN PERFORMED

Backup and then edit the config.tp script: -

# cd Ñ /etc/trueport ¿

# cp Ñ config.tp Ñ config.tp.orig ¿

# vi Ñ config.tp ¿

On the line for the port amend ka 30 to be ka 0

E.g. /usr/bin/trueportd -tty /dev/term/X0007 -port 10007 -ka 0

You can now use option 2 in the TruePort menu (tp.menu) to reset a specific TruePort daemon to bring into effect the changes or if there are a number of TruePort processes that have been amended, then a system reboot would be a preferable option
