【求助】關於DNS 代管 & DNS server 架設的問題
最近換了ISP是H牌 3M/512K 固3IP
偶用ADSL 在公司架設了 web,ftp,mail server
由於之前是ISP有提供 DNS 代管的服務
現在換了ISP, hinet 並無提供DNS代管 現在問題來了
自己在NAT內用win2000server架設的DNS server(使用真實IP) 在區網內測試沒啥問題
返家後 用nslookup 查詢 一直出現timeout tcp 53 有開呀
沒將 server 設到ip 分享器的DMZ 一直無法提供DNS查詢
訊息如下:
C:\>nslookup
DNS request timed out.
timeout was 2 seconds.
*** Can't find server name for address 220.130.5x.x: Timed out
Default Server: UnKnown
Address: 220.130.5x.x
> set q=any
> abx.com
Server: UnKnown
Address: 220.130.5x.x
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Request to UnKnown timed-out
將這部server 設到ip 分享器的DMZ 可以查詢一次然後又不行了
而且又有安全性的問題
訊息如下:
C:\>nslookup
*** Can't find server name for address 220.130.5x.xx: Non-existent domain
Default Server: UnKnown
Address: 220.130.5x.xx
> set q=any
> abx.com
Server: UnKnown
Address: 220.130.5x.xx
abx.com nameserver = ns1.abx.com
abx.com
primary name server = ns1.abx.com
responsible mail addr = admin.abx.com
serial = 8
refresh = 900 (15 mins)
retry = 600 (10 mins)
expire = 86400 (1 day)
default TTL = 3600 (1 hour)
abx.com MX preference = 10, mail exchanger = w1.abx.com
ns1.abx.com internet address = 220.130.5x.xx
w1.abx.com internet address = 220.130.5x.xx
> hinet.net
Server: UnKnown
Address: 220.130.5x.xx

這是怎回事呀 ? win2kserver 頂不住不穩嘛 ? 在區網內測試沒啥問題耶
除了tcp 53 要開 還有哪些port 要開呢 ?
哪裡有DNS代管的服務? 自己功力不夠弄不起來只好花錢消災了
不然偶是想自己試試看 再說若是自己有DNS server 要更改個啥設定 也不需去拜託人家改
希望各位大大給個建議 幫幫小弟的忙 救救偶啦
線路一更換 dns 指向沒搞好 web server 連不上 e-mail 收不到 老闆會抓狂耶
