Re: [ns] after installing ns2.1b8

[Nipul Jayvant Shah <njshah@unity.ncsu.edu>]

Hi! thank you very much for your reply. However I have been having some
problems after setting the environment variables. I am using tcsh shell.
so after using setenv for PATH, LD_LIBRARY_PATH and TCL_LIBRARY, a lot of
commands stopped working in linux. I couldn't even use 'ls', 'cd',
'pwd'... even 'ns' stopped working. it just keeps saying 'command not
found'. did i do something wrong?

below are the exact commands that i used at the prompt (after ns installation):
setenv 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
setenv LD_LIBRARY_PATH /ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/otcl-1.0a7:/ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/lib
setenv TCL_LIBRARY /ncsu/mmtech/incoming/njshah/ns-allinone-2.1b8/tcl8.3.2/library

Could you please help me with this?
thanks in advance.
