nameserver 肯定是没有错的

还是你的DNS配置有问题\r\n# wget ftp://ftp.sunfreeware.com/pub/freeware/intel/8/tcpdump-3.8.1-sol8-intel-local.gz \r\n--11:41:05--  ftp://ftp.sunfreeware.com/pub/freeware/intel/8/tcpdump-3.8.1-sol8-intel-local.gz\r\n           =>; `tcpdump-3.8.1-sol8-intel-local.gz\'\r\nResolving ftp.sunfreeware.com... 66.193.208.66\r\nConnecting to ftp.sunfreeware.com[66.193.208.66]:21... connected.\r\nLogging in as anonymous ...

应该不是的，我用外部也不行\r\n\r\n# more /etc/resolv.conf\r\nnameserver 202.102.14.141\r\n# nslookup www.google.com\r\nServer:  dns.sz.js.cn\r\nAddress:  202.102.14.141\r\n\r\nNon-authoritative answer:\r\nName:    www.google.akadns.net\r\nAddresses:  66.102.11.99, 66.102.11.104\r\nAliases:  www.google.com\r\n\r\n# ping www.google.com\r\nping: unknown host www.google.com\r\n# nslookup ftp.linuxforum.net\r\nServer:  dns.sz.js.cn\r\nAddress:  202.102.14.141\r\n\r\nNon-authoritative answer:\r\nName:    ftp.linuxforum.net\r\nAddress:  61.152.210.194\r\n\r\n# ftp ftp.linuxforum.net\r\nftp.linuxforum.net: unknown host or invalid literal address\r\nftp>;

原来是这样的， resolv.conf nsswitch.dns 等 都市配置正确的， 是应为\r\n\r\nnsswitch.confi 中  hosts: file  没有加 dns , 该为,  hosts: file dns 就行了

\r\n我倒，没配这个DNS也能通？

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
