nslookup 的結果...
如果我單用eth1是可以正常的, 但是eth0兩個介面一起開,就有問題
[root@localhost ~]# nslookup www.google.com.tw
;; connection timed out; no servers could be reached
※ 引述《nosrep (真相)》之銘言:
: 我的系統是 Linux, eth0是內網, eth1是外網.
: 我用 ping的方式, dns server, 目的ip都是通的
: 我想應該是轉譯的問題...
: 但是系統的設定看似乎都是對的, routing table也沒什麼問題...
: 哪位大大幫忙診斷一下~~XD
