Hi, all
After having made some modification on a Network driver, I found that
the ping program on another machine can't recognize the "icmp: echo
reply" message from this driver. Yes, I monitered the packets by
tcpdump and it shows the "icmp: echo reply" message was received. Why
the "ping" program can't recognize them?
And I also found that the DF flag of "icmp: echo reply" message was
not set, how can I force the TCP/IP layer to set that flag?
Thanks
Victor
