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]

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!
