1. Two boxes.
2. Both Mandrake 6 distro. 2.2.16 kernel.
3. All networking compiled in.
4. Both use 3C905b ISA nics.
5. One box has PnP bios, nic has PnP disabled.
6. Other box has no PnP, PnP not disabled on nic.
7. IRQ 12, 240h
8. Both boxes see the card on boot, everything looks good.
9. /proc/net/dev /proc/net/route /proc/interrupts
   show eth0 as expected.
8. Both boxes configured with /etc/hosts entries
referencing the other:

/etc/hosts (same for each):
127.0.0.1    localhost.localdomain  localhost
172.16.5.4   cruiser.wonder.net     cruiser
172.16.5.3   galleon.wonder.net     galleon

- last line in rc.local:
/root/net/setupnet

- /root/net/setupnet:

galleon:
ifconfig eth0 172.16.5.3 netmask 255.255.255.0 broadcast 172.16.5.255
route add -net 172.16.5.0 netmask 255.255.255.0 eth0

cruiser:
ifconfig eth0 172.16.5.4 netmask 255.255.255.0 broadcast 172.16.5.255
route add -net 172.16.5.0 netmask 255.255.255.0 eth0

No errors.

Both boxes can ping themselves but not each other.

At cruiser:
$ telnet galleon
Trying 172.16.5.3...
$telnet: Unable to connect to remote host: No route to host

At galleon:
$ telnet cruiser
Trying 172.16.5.4...
telnet: Unable to connect to remote host: No route to host

I'm at a loss. I've read everything in sight, from the NAG to
Craig Hunt's "Linux Network Servers 24/7."

Can't make it work. Need help.

Mike

sorry mike,
need more info.
what does 'ifconfig' tell you,
or,
what does dmesg|grep eth tell you ?
from both machines, please.

next,
hardware approach,
hub?crossovercable?
tried a different port on hub yet?
different cables?
can you test that part of your network somewhere else,
like between 2 other machines ?

tried your machines with any of those winblows os's ?
(meaning, are you SURE your hardware works?)

last resort, try tcpdump on one machine,
while pinging on the other,
(and vice versa)
see if theres any traffic at all.

1. simulate UDP packet loss. Help needed!!

I am doing a project to simulate the erratic environment of the Internet,
behaviors such as packet loss, error bit, duplicate packets etc.

Now I want to send the data, a video stream, but instead of receiving it at
the client side, I want to collect the UDP packets at the transportation
layer, and manipulate the packets, that is inject errors into them. After
error injection, send the UDP packets out.

First I thought I could use winsock, but soon I realized that the
application layer API is not able to handle the transportation UDP packets.
Some questions pop up are:
    * How do I receive packets at transportation layer?
    * May I send the UDP packets directly to disk to save as a file?
    * Is there any library or programming interface I can use to handle this
kind of situation?

Looking forward to any help and remarks.
