Hello,

Thank you.
By
echo flush >'#a/arp/ctl'
on v2 cpu/terminal. CPU servers get connected.
But how can I do for my file server?
Reboot?

try this.

echo flush >'#a/arp/data' on v2 cpu/terminal

arp flush (i think) on a v2 file server console

and things might spring to life.

by changing the card you changed the MAC address
and thus the IP to MAC translation
but v2 systems will still retain the original translation until
you tell it otherwise.  they will be sending to the card
that's now truly on the ether (out in the air).

Hello,

I am in trouble.
I swapped my ether card from ne2000 to 3c905b.
The machine is standalone Plan9v3 terminal.
The result is weird.
The machine can communicate with UNIX using telnet --- not weird.
The machine turned unable to communicate with Plan9v2 servers
both on il and tcp --- weird!.
Plan9v2 servers are working as they have been --- not weird.
Snoopy can catch their packets at both end, that is, packets can  
reach
the target mutually.
Their conversations suggest that v2 and v3 cannot synchronize.
All my v2 servers are running with 10M ether card,
and machines are connected using 10/100 switching HUB.

Suggestion welcome.
