Check the settings of the script with ls -l ./install, and adjust as necessary.

This is a permission problem; it should be run under "sudo" -- I answered, please see.

It's normal, as installations usually require superuser permissions. Run:

sudo ./install

You will be prompted for your account login password; to pass, your account also needs to have sufficient privileges to play as a superuser. Please see: http://en.wikipedia.org/wiki/Sudo[^].

sori to say , i have already try this, but when i m using this , i get following error..

sudo: ./install: command not found

Espen Harlinn 4-Jan-12 16:33pm

do a 'pwd' and 'ls -l'

Sergey Alexandrovich Kryukov 4-Jan-12 18:49pm

I based my answer on your report in the ./install. Check up that the install file is there, check up everything "ls -l". Make sure you do this attempt on the same directory as the first one, otherwise your observation contradict to each other. I gave your the explanation of what happened, now use it. Unfortunately, I don't have access to your hard drive. Learn what install and sudo do, separately, and combine them.

After installation i have found this,
dont know how to proceed, please help,..

Please put /home/tassi/Desktop/NS-Installation/ns-allinone-2.34/bin:/home/tassi/Desktop/NS-Installation/ns-allinone-2.34/tcl8.4.18/unix:/home/tassi/Desktop/NS-Installation/ns-allinone-2.34/tk8.4.18/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put /home/tassi/Desktop/NS-Installation/ns-allinone-2.34/otcl-1.13, /home/tassi/Desktop/NS-Installation/ns-allinone-2.34/lib,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to your X libraries
into LD_LIBRARY_PATH.
If you are using csh, you can set it like:
setenv LD_LIBRARY_PATH <paths>
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=<paths>

(2) You MUST put /home/tassi/Desktop/NS-Installation/ns-allinone-2.34/tcl8.4.18/library into your TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.

After these steps, you can now run the ns validation suite with
cd ns-2.34; ./validate
