Re: [ns] Two problems in running ns2

["HsinChi" <m8945@cn.ee.ccu.edu.tw>]

I try to describe my problems more details.

I run ns2 on Linux Mandrake release 7.0 (Air) + CLE v0.9 (Yami)
                   Kernel 2.2.14-15mdk on an i686

Two questions:
1.
 I need node_(2) to send a message to node_(1).

I do not know how to use Agent/Message.

So I modify the example ping.tcl which is introduced in Marc Greis's
tutorial.

I just change [new Agent/Ping] to [new Agent/Message]

It shows the error messages as follow:

 ns: _o56 send:
    (_o56 cmd line 1)
    invoked from within
"_o56 cmd send"
    invoked from within
"catch "$self cmd $args" ret"
    (procedure "_o56" line 2)
    (SplitObject unknown line 2)
    invoked from within
"_o56 send"

2.
I download the example wireless2.tcl  in Marc Greis's tutorial.

I can not run it in ns2.1b6 version.

It shows

uneven number of args
    (Object init line 1)
    invoked from within
"addr2id init 1.0.0"
    (Class create line 1)
    invoked from within
"AddrParams create addr2id 1.0.0"
    ("eval" body line 1)
    invoked from within
"eval [list $self] create [list $m] $args         "
    (procedure "AddrParams" line 5)
    (Class unknown line 5)
    invoked from within
"AddrParams addr2id  [$BS(0) node-addr]"
    invoked from within
"for {set j 0} {$j < $opt(nn)} {incr j} {
    set node_($j) [ $ns_ node [lindex $temp \
            [expr $j+1]] ]
    $node_($j) base-station [AddrParams add..."
    (file "wireless2.tcl" line 138)

 I can run it in ns2.1b8 version but still it shows some warning message as

warning: Route to base_stn not known: dropping pkt
warning: Route to base_stn not known: dropping pkt
MAC_802_11: accessing MAC cache_ array out of range (src 3, dst 1, size 3)!
warning: Route to base_stn not known: dropping pkt
warning: Route to base_stn not known: dropping pkt

 Is the example correct  or something wrong in ns2.1b6 version ?

Thanks
