Hello all,
  I have downloaded ns-2 recently but am having problems running the
file test-all-red. Specifically at the point test red_twoway I get the
message 
Running test red_twoway
warning: using backward compatibility mode
invalid command name "Source/telnet"
    while executing
"Source/telnet create _o77"
    ("eval" body line 1)
    invoked from within
"eval $className create $o $args"
    (procedure "new" line 3)
    invoked from within
"new Source/$type"
    invoked from within
"set src [new Source/$type]..."
    (procedure "_o74" line 5)
    invoked from within

    invoked from within
"set telnet1 [$tcp4 source telnet]..."
    (procedure "test_red_twoway" line 19)
    invoked from within
"test_$argv"
    (file "test-suite-red.tcl" line 638)
next?

The above repeats with slight changes of course for test red_twowaybytes
and on. So was wondering if I am missing the files such as telnet and
later flowmgr for test_flows. I would appreciate any input in this
matter. Please email your replies to farooq@glue.umd.edu. Thanks very
much.
