Internet------Router(dhcp, nat).....my notebook(freebsd 5.4)
我notebook 是用ipw無線網路連線
一直以來就一直有個網路問題
就是從notebook要連一個位址 像ptt.cc
他都會出現說"連不到" 多試幾次才可連
像
> telnet ptt2.cc
ptt2.cc: hostname nor servname provided, or not known
Exit 1
> telnet ptt2.cc
Trying 140.112.90.73...
Connected to ptt2.cc.
Escape character is '^]'.
我察看tcp的traffic 發現似乎是dns的問題
Time Source Destination Protocol Info
50.300 192.168.1.4 192.168.1.1 DNS query A ptt.cc
50.594 192.168.1.1 192.168.1.4 DNS query response
50.594 192.168.1.4 192.168.1.1 DNS query AAAA ptt.cc
50.679 192.168.1.1 192.168.1.4 DNS query response
50.679 192.168.1.4 192.168.1.1 DNS query A ptt.cc
50.778 192.168.1.1 192.168.1.4 DNS query response
50.778 192.168.1.4 192.168.1.1 DNS query AAAA ptt.cc
50.928 192.168.1.1 192.168.1.4 DNS query response
// 以上我ptt.cc的正解都還沒有結果
.....
63.528 192.168.1.4 192.168.1.1 DNS query A ptt.cc
63.590 192.168.1.1 192.168.1.4 DNS query response A 140.112.90.72
63.590 192.168.1.4 192.168.1.1 DNS query AAAA ptt.cc
63.653 192.168.1.1 192.168.1.4 DNS query response
63.653 192.168.1.4 140.112.90.72 TCP 56738 > telnet [SYN] Seq=0 Ack=0 ...
64.063 140.112.90.72 192.168.1.4 TCP telnet > 56738 [SYN, ACK] Seq=0 ...
// 現在才解出ptt.cc 的ip 成功連線...
請問各位我要怎麼解決這個問題呢
router應該沒問題 網內其他電腦(windows)都沒這個問題
這樣的問題是什麼呢 dna cache? flush?
還是那些地方timeout太快了(明明多等一下 ip就察出來了...T_T)
目前還沒概念耶???
