Welcome to LQ.

A corrupt package. Suggest : Delete "ns-allinone-2.31.tar.gz".
And download a new one from ..
http://sourceforge.net/projects/nsna...allinone-2.31/ >
> http://surfnet.dl.sourceforge.net/pr...ne-2.31.tar.gz

Unpack : tar xvf ns-allinone-2.31.tar.gz :
The v option will show the complete unpack, line by line.

You have a corrupt package, as previously stated, or you are trying to uncompress that package before it's finished downloading. I downloaded it, and it uncompressed just fine.

There are no problems with the source package as given to you by knudfl. The tar command may need to be "tar -xvfz" for a gzipped file....

Thank you a lot for your helpful site . I installed successfully ns2.31 but when i tape the $ source ~/.bashrc command i have this result :
bash: LIB:/usr/local/lib:no file or directory of this type

I have used the set variables here:

Code:

# LD_LIBRARY_PATH
OTCL_LIB=/home/abc/ns-allinone-2.31/otcl-1.13
NS2_LIB=/home/abc/ns-allinone-2.31/lib
X11_LIB=/usr/X11R6/lib
USR_LOCAL_LIB=/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_
LIB:$USR_LOCAL_LIB

# TCL_LIBRARY
TCL_LIB=/home/abc/ns-allinone-2.31/tcl8.4.14/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH
XGRAPH=/home/abc/ns-allinone-2.31/bin:/home/abc/ns-allinone-2.31/tcl8.4.14/unix:/home/abc/ns-allinone-2.31/tk8.4.14/unix
NS=/home/abc/ns-allinone-2.31/ns-2.31/
NAM=/home/ines/ns-allinone-2.31/nam-1.13/

Please help me .Thanks

Don't. Not required for Linux.
This will do : 1) cd ns-allinone-2.31/ns-2.31/ && sudo make install
2) sudo apt-get install xgraph ( The ns2 xgraph is never working.)
3) Nam : Please use a "nam package". Post # 4 here
http://www.linuxquestions.org/questi...04-a-842109/#4
> nam-1.14.i586.tar.gz
cd nam-1.14.i586/ && sudo cp nam /usr/local/bin/
