我在安装完ns2之后。按照安装说明，在设置好环境变量之后，执行ns并没有出现%，二十出现了下面的代码：
ddd@ddd-laptop:/usr/local/ns-allinone-2.31$ 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 ...]]
请问谁知道这是算成功了，还是安装有问题？

我也是同樣的問題...不過我在安裝的時候他出現很多的警告
請問各位也有碰到同樣的問題嗎

run过test了吗？

ubuntu 的 ns 命令是指向host的，所以当出现sudo apt-get install host的时候不要安装，如果已经安装了的话，执行sudo apt-get remove host，然后在NS目录下执行 ./install重新安装

我也遇到过这个问题
只要用ln链接到你安装ns的目录下就可以了
