Idle TCPIP connections dropping?

» close window

The Question is:

 
ucx problem
I am getting auto logout'd after 10 minutes idle.
 
I recently got a vaxstation 2000 with vms 4.6,
6Mb ram and 150Mb hard disk. No tape drive.
The local vms guru helped me upgrading it to 6.0
and add ucx for tcp/ip.
 
My telnet and relogin sessions are automatically
closed after 10 minutes. That is the case both
at work and at home where the vax is now.
 
In all cases I login from a linux pc with linux-2.0.34,
at work there is a cisco pix firewall in between. At
home the linux and the vms box are directly on the
same ip network.
 
I wonder if it is a settable timeout. I have tried
to change mc sysgen, TTY_TIME and ucx UXC$KEEP_ALIVE.
No help.
 
The printer port which I use for a serial console
does not have the problem.
 
Note: linux does some random tcp sequence numbering.
I think the cisco pix does too. I don't know if
that matters.
 
VMS is new, and I like to play with it.
 
 

The Answer is :

 
  TCP/IP Services for OpenVMS (UCX) does not typically drop sessions
  automatically, idle or otherwise.
 
  The Wizard would check to see if there is a setting on the firewall
  system or an associated router that is configured to drop an idle
  connection, or if there is a site-configured idle process monitor
  running on the system.
 
  If this is a hobbyist system, see if DECUS offers a hobbyist OpenVMS
  license in your area.  (The site http://www.montagar.com/hobbyist/ has
  more information on the DECUS OpenVMS VAX V6.1 hobbyist license.)
