[ns] error about "nam:error reading last line in trace.nam" under Red Hat7.1

["=?big5?q?babulia.tw?=" <babulia.tw@yahoo.com.tw>]

Dear Sir:

     I'm sorry if this causes you any problem. I'd
like to ask you a question.
     I have installed ns-allinone-2.1b8a under the
"Red Hat7.1" platform. And I used Nam to figure my
desired topology out.I saved it as "test.ns". Case1:
After running NS by issuing the following command
"#nam test.ns", error happened. The following is those
message[nam: eroor reading the last line
"trace.nam"]. What happened? Case2:I ran ns by using
the command with the graphical Nam progam. The NS
process became zomebie.What happened?
  
Finally,thank you for your help.

Best regard,
Andy Chen
