Re: [ns] after installing ns2.1b8

As it is stated on the message, you have to set some enviroment variables.

First you must find your shell (bash, sh, csh, ...)

type set | more and look for a line SHELL=

if it is bash or sh, then use the command export VARIABLE=value
eg.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/otcl-1.0a7:
/ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/lib

for the PATH

export
PATH=$PATH:/ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/bin:/ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/tcl8.3.2/unix:/ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/tk8.3.2/unix

and

export TCL_LIBRARY=$TCL_LIBRARY:/ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/tcl8.3.2/library


All the above export commands are to be issued in one line.
If you have bash, then you can include the above commands in .bash_profile in your home directory, so that you don't have to type them every time.

Other shells have also configuration files, like .cshrc for csh, but unfortunately I am not an expert on Unix to know them all.

if it is csh, I guess you can use the command setenv VARIABLE value.

Hope it helps
