How does one disable IP forwarding?  I have a complex network
where a lot of hosts are sending UDP packets which other hosts
(non-gateways) relay to their default gateways.
Does anyone know where I can good write-up on routed?

Can't someone do something about this?  It's got to be one of the least
informative subject lines in existence, right up there with "(none)".
Can't the BITNET gateway be kludged to recognize when it's about to
generate a posting with this subject and do something more useful?

> How does one disable IP forwarding?

This depends on the gateway machine software.  For Berkeley UNIX, 4.3
at least, there's a kernel variable called ipforwarding which can be
set to 0 to disable forwarding.  To change it, use adb:

% adb -w -k /vmunix /dev/mem
_ipforwarding/W 0			<- in running system
_ipforwarding?W 0			<- in kernel file
$q

Changes made to the running system take effect immediately but go away
at next reboot; changes made to the kernel file are permanent but don't
take effect until next reboot.  (Well, permanent until you rebuild an
new kernel and install it.  To fix it *really* permanently, change the
initialization in netinet/ip_input.c (or you may be able to use a
config file line

options		"IPFORWARDING=0"

).)

Re: 3com PCS/TCP-NS and TN3270

Sorry for the multiple posting.

We are begining to use PCS/TCP, a package designed for a 3Com network, and
wanting to use TN3270.  Line mode on an IBM VM/CMS system is fun, but...

Has anyone *actually* combined any of the various TN3270 packages and
this telnet?  Perhaps more properly stated, has someone used a TN3270
and the driver and etc. from this package.

It does not have a TN3270 of it's own.

If so, I'd like to know and if wanted I'll post any results.

    Does anyone out there know of a Name Server that will run on SCO XENIX/UNIX
or a SUN SPARC Workstation running SUNOS?  We are implementing a Class B
Ethernet connecting SUN Workstations to a Silicon Graphics Supermini Computer
and to an IBM Token Ring through a Wollongong Gateway.
    Please reply directly to me (MTSJLM@GSUVM1.BITNET).
