SubjectNo forwarding
I can't get Version: 
Linux chaos 2.1.21 #5 Wed Jan 15 16:03:43 EST 1997 i586

... to route packets! Yesterday (no configuration changes) it did after
mucking around for about an hour.

My remote ppp link is called skunkworks in the following script. The
route gets added as expected.

/etc/proxy_all is a little program that tells arp to auto-arp everything.
It was advised by the ip4v code developer and worked yesterday.
#
# startup script. Executed after the ppp link is up.
#
/sbin/route add -net 204.178.47.0 netmask 255.255.255.0 gw skunkworks
echo 1>/proc/sys/net/ipv4/ip_forwarding
/etc/proxy_all

Now, cat /proc/sys/net/ipv4/ip_forwarding always shows "2". Regardless of
what I set. All the "files" in proc/sys... are read-only regardless of
what I do.

I don't understand "having to turn ON" IP forwarding when it was compiled
in the kernel. Older versions of the Network Software worked for 2 or more
years without this. Nevertheless, I followed the limited instructions
available and the software only works sometimes.

Further. I can't delete a route 'route' doesn't report the kind of error,
but a program shows the 'errno' is "no such process". This is the kind
of error one would expect from kill(), not ioctl().

The "new stuff" in /proc makes it impossible to dismount /proc. It is
always 'busy'. Therefore, I can't reboot without a long fsck upon startup.

When I was at my machine console, I was previously always able to dismount
all the file systems manually for a quick re-boot. Can't do that anymore.

If I don't start the network. I can still dismount /proc. The /proc file-
system becomes busy ONLY AFTER I attempt to write to
/proc/sys/net/ipv4/ip_forwarding...


Cheers,
Dick Johnson
