在台南的家裡申請的adsl是早期TTN台灣電訊的固4 IP，最早是512/64 幾年前電路升到1M/64，後來TTN被台灣大寬頻併掉後，固定IP繼續保留使用在去年底電路又升到2M/128，連到ATU-R去看，局端所設定的值還設到2400k/160k(如下) Adsl Line Status OPERATIONAL Adsl Mode G.DMT Up Stream 160 kb (Interleave) Down Stream 2400 kb (Interleave) Attenuation Near End: 19.5 Far End: 24.5 SNR Margin Near End: 28 Far End: 18 HEC Count 0 Firmware 0x41e2be1f 15 min ES Counter 0 CRC Errors 0 1 day ES Counter 0 問題是連線的品質一直不理想，看了ping值實在讓人不敢領教，都要5x ms起跳做了一些測試，問題應是出在家裡到gateway這段的ping太高... 從台北去ping台南機房裡的gateway，還比台南家裡的機器ping台南的gateway還快... 請問我該如何解決會比較好吧？以下是ping測試，家裡的固定IP是在210.192.63.0/24這網域，default gateway是210.192.63.254 1.家裡linux ping gateway [sssun][/home/sssun] ping 210.192.63.254 PING 210.192.63.254 (210.192.63.254) 56(84) bytes of data. 64 bytes from 210.192.63.254: icmp_seq=1 ttl=127 time=77.0 ms 64 bytes from 210.192.63.254: icmp_seq=2 ttl=127 time=54.4 ms 64 bytes from 210.192.63.254: icmp_seq=3 ttl=127 time=57.5 ms 64 bytes from 210.192.63.254: icmp_seq=4 ttl=127 time=139 ms 64 bytes from 210.192.63.254: icmp_seq=5 ttl=127 time=55.6 ms --- 210.192.63.254 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 3999ms rtt min/avg/max/mdev = 54.433/76.861/139.580/32.433 ms 2.家裡linux ping 台灣大寬頻的dns，很明顯的問題是出在家裡到gateway這條 [sssun][/home/sssun] ping 211.78.215.137 PING 211.78.215.137 (211.78.215.137) 56(84) bytes of data. 64 bytes from 211.78.215.137: icmp_seq=1 ttl=58 time=65.5 ms 64 bytes from 211.78.215.137: icmp_seq=2 ttl=58 time=56.5 ms 64 bytes from 211.78.215.137: icmp_seq=3 ttl=58 time=223 ms 64 bytes from 211.78.215.137: icmp_seq=4 ttl=58 time=58.0 ms 64 bytes from 211.78.215.137: icmp_seq=5 ttl=58 time=57.0 ms 64 bytes from 211.78.215.137: icmp_seq=6 ttl=58 time=59.3 ms --- 211.78.215.137 ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5012ms rtt min/avg/max/mdev = 56.523/86.747/223.984/61.447 ms 3.學網ping 家裡機器的default gateway，這裡的反應還滿快的啊從台北去ping台南機房裡的gateway，還比台南家裡的機器ping台南的gateway還快 [ns2][/home/sssun] ping 210.192.63.254 PING 210.192.63.254 (210.192.63.254) 56(84) bytes of data. 64 bytes from 210.192.63.254: icmp_seq=1 ttl=118 time=7.43 ms 64 bytes from 210.192.63.254: icmp_seq=2 ttl=118 time=15.0 ms 64 bytes from 210.192.63.254: icmp_seq=3 ttl=118 time=9.11 ms 64 bytes from 210.192.63.254: icmp_seq=4 ttl=118 time=7.69 ms 64 bytes from 210.192.63.254: icmp_seq=5 ttl=118 time=7.94 ms --- 210.192.63.254 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4000ms rtt min/avg/max/mdev = 7.439/9.446/15.046/2.860 ms -- 抽煙潤肺喝酒保肝吸毒醒腦吃冰治咳嗽嚼檳榔顧牙齒 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.42.109
