Problems running ns examples

[Nguyen Huu Thanh <thanh@informatik.unibw-muenchen.de>]

Hello everybody,

While trying the examples located at ~ns/tcl/ex with ns-allinone-2.1b5,
I encounted some problems that I don't understand and could not find any
solution in the fixed bug document. The following error messages are
some examples:

1. When running hier-rtg-100.tcl:

....
_o3: unable to dispatch method duplex-link-of-interfaces
    while executing
"$ns duplex-link-of-interfaces $n(0) $n(75) $linkBW 410ms DropTail"
    (procedure "create-hier-topology" line 126)
    invoked from within
"create-hier-topology $linkBW"
    (file "hier-rtg-100.tcl" line 15)


2. in many_tcp.tcl:

....
ns: close file3; _o3 finish: syntax error in file ../../bin/raw2xg at
line 43, next 2 tokens "my("
syntax error in file ../../bin/raw2xg at line 59, next 2 tokens
"translate_point
("
syntax error in file ../../bin/raw2xg at line 94, next 2 tokens
"translate_point
("
Execution of ../../bin/raw2xg aborted due to compilation errors.
    while executing
"exec ../../bin/raw2xg -a  -q -n 1 < out.tr >out.xg"
    ("eval" body line 1)
    invoked from within
"eval "exec $cmd""
    (procedure "_o3" line 33)
    (Main finish line 33)
    invoked from within
"_o3 finish"


3. in manytcp_trmodel.tcl:

invalid command name "TrafficGen/ManyTCP"
    while executing
"TrafficGen/ManyTCP create _o10 -print-drop-rate 1 -debug 0
-trace-filename out -bottle-queue-length 50 -bottle-queue-method RED
-client-arrival-rate 1..."
....

4. in srm-adapt-req-session.tcl:

invalid command name "0"
    while executing
"$from id"
    (procedure "_o4" line 6)
    (SessionSim insert-loss line 6)
    invoked from within
"$ns insert-loss $loss_module 0 $i"
    (file "srm-adapt-req-session.tcl" line 73)


Thanks for any kind help.

Regards, 

Thanh

P.S: I have rebuilt ns-allinone-2.1b5 in HPUX10.20 and been able to run
some other examples.
