Where else do I set mtu's except for the pppd dialer (linux to the
'net)...and is there a good way of finding out the exact mtu? (the isp
doesn't know...their cust. svc is not tech support and they are a bit too
big to care about the little guy...problem is ..they are the only ricochet
modem ppp provider around San francisco) My ppp0 is defaulted to 1500 mtu
at i set the modem at a 57600 connection speed.
Yup...can ping linux from winnt and vice versa...currently i have a nohup
ping process going from the linux box to winnt (lotsa traffic...but only
two machines on the network anyway...so it really doesnt matter) This
pinging is allowing instant access to the net...
slow..but instant.

Jann,
Can you ping anything outside your network from the WinNT box? From the
Linux box?
It may not help, but it's something else to check, but check the MTU
everywhere you can think of. I had some strange problems 'cause I had some
MTUs set differently.
We have a machine here with a flaky ethernet card. If I do a ping -f
<ip.addr> it drops about 5 packets a second. Not good. Maybe one of your
nic's is problematic?

The only thing that makes me think this is not true is that I have netstat
-Mc running constantly and it is not listing any connections when this
occurs...the gateway in the client machines is listed as an ip # so i
wouldn't think this is a problem...
But...as they say, thanks for taking the time to think about it...it gives
food for thought.

Greetings.
It might have something to do with DNS entries expiring perhaps. If you
keep pinging then possibly the DNS entries would stay there. If there was
no activity maybe the DNS entries would expire and be removed from the
cache.
I noticed that if my Linux machine (before I connected it to the network)
could not resolve a name locally it would try to contact the next higher
DNS, but not being connected could not, so it timeouted, but this took a
few seconds.
You can try doing a ipfwadm -M -l (lowercase ell) which will list the
masquerading entries, and show you the times those expire as well.

Anyone heard of IP Masquerade running on linux kernel 2.0.32 listening
closer if you continually ping a client machine?
my client is winnt and if i set linux to continually ping it, then the
linux box receives an acts on TCP requests from the winnt box
faster...sometimes it doesn't recognize the winnt box ax all...here are the
commands and routing i am using on the linux box.
> ipfwadm -F -f
> ipfwadm -F -p deny
> ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0
Leaving out the Metric, Ref and Use as they would not tell you anything--
Destination Gateway Genmask Flags Iface
mg134-198.domain * 255.255.255.255 UH ppp0
192.168.1.0 * 255.255.255.0 U eth0
127.0.0.0 * 255.0.0.0 U lo
default mg134-198..domain 0.0.0.0 UG ppp0
Thanks in advance for advice.
Jann
(bad day!) ;(
