hello,
i followed one NS 2.31 installing page, but on the step that i type 'ns' on console instead of appearing an %, the following error occured :

:~$ ns
Usage: host [-v] [-a] [-t querytype] [options] name [server]
Listing: host [-v] [-a] [-t querytype] [options] -l zone [server]
Hostcount: host [-v] [options] -H [-D] [-E] [-G] zone
Check soa: host [-v] [options] -C zone
Addrcheck: host [-v] [options] -A host
Listing options: [-L level] [-S] [-A] [-p] [-P prefserver] [-N skipzone]
Common options: [-d] [-f|-F file] [-I chars] [-i|-n] [-q] [-Q] [-T] [-Z]
Other options: [-c class] [-e] [-m] [-o] [-r] [-R] [-s secs] [-u] [-w]
Special options: [-O srcaddr] [-j minport] [-J maxport]
Extended usage: [-x [name ...]] [ -X server [name ...]]
:~$

can you help me? what is the problem?

or otherwise can you tell me how to uninstall ns, to follow the these steps again from the beggining ?

Thanks!

It's telling you how to use ns. Typing ns alone doesn't do anything, it requires various parameters depending on your needs, and these are what you are being shown above

What are you trying to do with the ns command? It appears that it is looking for more arguments by the output listed above.

--B

<lolcats>ns. ur doin it wrong!</lolcats>

well, it should appear a %, that would mean i entered the program, i think... and if i try to run the application with arguments the following error occurs:

$ ls
bin install ns-2.31 sgb tk8.4.14
cweb INSTALL.WIN32 ns-simple.tcl tcl8.4.14 xgraph-12.1
example1a.tcl lib otcl tclcl zlib-1.2.3
gt-itm man otcl-1.13 tclcl-1.19
include nam-1.13 README tcp-veno-1.0.2
$ ns example1a.tcl
example1a.tcl does not exist, try again
$
