SAMBA服务器访问慢

jensen

用户 127个,但平时在线的在20个左右
服务器 IBM X346 内存 2G CPU Intel(R) Xeon(TM) CPU 3.20GHz
文件数比较大 差不多 150G
所有的文件都在上面 5个硬盘做的 RAID 5    1个热备

服务器跑了半年多没有问题.上次关机重启后问题就出来了.访问服务器的时候要等个15秒...访问品牌图片和部门文件JIA时也要等到几十秒,慢的不行.  下面贴出详细的CONFIG .大家帮忙看看是哪里出问题了

谢谢版主,通过抓包发现 竟然有到 dns 的包 ...
原来服务器的 /etc/resolv.conf  不知被谁设了一个不存在的 dns server ip  202.96.134.134
删除这个ip 重启 SAMBA 后问题解决

新的疑问, 既然dns proxy = No 为什么还会往 dns 发包.真的很奇怪

不知是不是 name resolve order = wins lmhosts hosts bcast  这行的原因
