SAMBA伺服器訪問慢
用戶 127個,但平時在線的在20個左右
伺服器 IBM X346 內存 2G CPU Intel(R) Xeon(TM) CPU 3.20GHz
文件數比較大 差不多 150G
所有的文件都在上面 5個硬碟做的 RAID 5 1個熱備
伺服器跑了半年多沒有問題.上次關機重啟后問題就出來了.訪問伺服器的時候要等個15秒...訪問品牌圖片和部門文件JIA時也要等到幾十秒,慢的不行. 下面貼出詳細的CONFIG .大家幫忙看看是哪裡出問題了

《解決方案》
不知用的是什麼版本的samba?
PS：出現關題時，首先應該看的是日誌
《解決方案》
版本 3.0.23a
日誌無異常 但就是慢,受不了了

《解決方案》
網路抓包看看
《解決方案》
謝謝版主,通過抓包發現 竟然有到 dns 的包 ...
原來伺服器的 /etc/resolv.conf 不知被誰設了一個不存在的 dns server ip 202.96.134.134
刪除這個ip 重啟 SAMBA 后問題解決
新的疑問, 既然dns proxy = No 為什麼還會往 dns 發包.真的很奇怪
不知是不是 name resolve order = wins lmhosts hosts bcast 這行的原因
