nameserver 肯定是没有错的

还是你的DNS配置有问题
# wget ftp://ftp.sunfreeware.com/pub/freeware/intel/8/tcpdump-3.8.1-sol8-intel-local.gz

应该不是的，我用外部也不行

# more /etc/resolv.conf
nameserver 202.102.14.141
# nslookup www.google.com
Server:  dns.sz.js.cn
Address:  202.102.14.141

外部也不行？没太懂

原来是这样的， resolv.conf nsswitch.dns 等 都市配置正确的， 是应为

nsswitch.confi 中  hosts: file  没有加 dns , 该为,  hosts: file dns 就行了

我倒，没配这个DNS也能通？

free2wind

是啊， dns 是去查 nsswitch,dns 这个 文件啊, 而其它应用 如 ftp ping telnet 是去查 nsswitch.conf 这个文件，我想是这样的
