[ns] Question on Network Emulation, fragment error of PingResponder!

Mon May 10 17:42:26 PDT 2004

hi,everyone
I just run the script which appears in "Network Emulation in the Vint/NS Simulator", and get the error message "fragment".
The PingResponder doesn't seem to send a feedback.
Because I ever succeeded in this script, I am confused now.
Can anyone help me?
