# 15

Maybe 'sudo tar xvf * ' was used for the unpack ?
Or 'sudo ' for a later command ?

Deleting : $ sudo rm -rf ns-allinone-2.34/

The above are some of 119 group tests, used for running the 2,000 tests.
* Some few tests will usually fail. Don't worry as long as everything else works.

$ './configure' is the wrong command.
Right is : $ export CC=gcc34 CXX=g++34 && ./configure ( If Fedora ).
EDIT : Ubuntu 12* : $ export CC=gcc41 CXX=g++41 && ./configure

# 19 .

Sorry, if Ubuntu 11* or 12*, it is of course :
export CC=gcc41 CXX=g++41 && ./configure


? Why do you type $ gcc -v
.. when you are not using gcc at all ? ? ( 'gcc41' is used.)

Better : $ g++41 --version

# 21 : Please edit your posts to use 'code tags'.
I.e. write [/code] at code text end, and [code] at start.

Quote:
"set bgp_agent0 [$n0 get-bgp-agent]"
I guess that `get-bgp-agent` is not a valid setting ?
Will test the file 'select.tcl' ... later.

# 26 .

All files but one (route-distrib.tcl) in ns-2.34/tcl/bgp/test/ work OK here.
All OK simulations will open nam automaticaly, except two :
reflection.tcl, reflection2.tcl. Nam works with :
$ nam reflection.nam
$ nam reflection2.nam

The files in ns-2.34/tcl/bgp/ : Not to be run.

About testing which Ubuntu that will work best :
I can upload an installable package "bgp-ns-2.34-ubuntu**_i386.deb" ~5 MB,
providing /usr/local/bin/ns-bgp , then you can test $ ns-bgp *.tcl.
I.e. it makes no difference which Ubuntu is used to run the executable
'ns-bgp', as long as it has been successfully built on another Ubuntu version.

The package bgp-ns-2.34-ubuntu1004_i386.deb (6.6 MB) can be downloaded from
https://docs.google.com/file/d/0B7S2...it?usp=sharing
.. And installed with "QApt Package Installer" or :
$ sudo dpkg -i bgp-ns-2.34-ubuntu1004_i386.deb

The package provides /usr/local/bin/ ns-bgp ns-bgp-rfd

Tested OK on Ubuntu 12.04. And the file route-distrib.tcl works too.

The 'ns-bgp-rfd' executable is for the two "bgp-rfd-mrai" examples,
ref. post # 25. ( tcl/bgp/test/ damping1.tcl damping2.tcl ).

The right command is : $ ns-bgp route-distrib.tcl
