[SOLVED] Error while running tcl file in ubuntu 12.04

mulyead · 11-13-2013, 06:41 AM

Hello,

I am using ns2.34 on Ubuntu 12.04. I installed NS2.34 on ubuntu and also able to install ns-BGP on it. While running a tcl script (which is downloaded from http://www2.ensc.sfu.ca/~ljilja/cnl/...-2.34-BGP.html) i am getting following error.

@ubuntu1204s:~/ns-allinone-2.34/ns-2.34/tcl/bgp/test$ ns drop-peer2.tcl

DROP-PEER2 Validation Test:

Three ASes connected in a line, each with one router.
AS 1 AS 0 AS 2
n1 }------{ n0 }------{ n2

(_o10 cmd line 1)
invoked from within
"_o10 cmd get-bgp-agent"
invoked from within
"catch "$self cmd $args" ret"
invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
(procedure "_o10" line 2)
(SplitObject unknown line 2)
invoked from within
"$n0 get-bgp-agent"
invoked from within
"set bgp_agent0 [$n0 get-bgp-agent]"
(file "drop-peer2.tcl" line 27)

Please help me with the solution of the same.

Thanks in advance
