display charset = cp950

一般人可能碰到一個問題叫做檔案鎖住?
為了避免一個檔案時被同時開啟,並各自變更資料而不知道,因
此有一種,機制叫lock,一個檔案開啟後另一個檔案只能以唯讀,
或被限制開啟
而Windows的網路芳鄰則有另一種機制,oplock:這一種方法是
予陶s接端可以暫存一些原本要存在server端的資料,且關閉時
不會直接關掉連線,如同所有的cache的作用,可以增加效能,然而
我的結果是檔案明明關閉很久,檔案卻一直被鎖住了,
以下是samba的oplock說明
oplocks (S)
This boolean option tells smbd whether to issue oplocks
(opportunistic locks) to file open requests on this share. The
oplock code can dramatically (approx. 30% or more) improve
the speed of access to files on Samba servers. It allows the
clients to aggressively cache files locally and you may want to
disable this option for unreliable network environments (it is
turned on by default in Windows NT Servers). For more
information see the file Speed.txt in the Samba docs/
directory.

這是我找到原說明中可以改善的這個問題
oplock break wait time (G)

This is a tuning parameter added due to bugs in both
Windows 9x and WinNT. If Samba responds to a client too
quickly when that client issues an SMB that can cause an
oplock break request, then the network client can fail and not
respond to the break request. This tuning parameter (which is
set in milliseconds) is the amount of time Samba will wait
before sending an oplock break request to such (broken)
clients.

DO NOT CHANGE THIS PARAMETER UNLESS YOU HAVE READ
AND UNDERSTOOD THE SAMBA OPLOCK CODE.

Default: oplock break wait time = 0

原意好像是說:有一些機器反應太快以至於無法中斷連線,因此
我調整oplock break wait time =20 至50,結果問題有效解決了
然而95還是有問題,因此我又加了keepalive=120 ,兩分鐘
因為網路內只有五,六台電腦,因此設兩分鐘,讓server檢
查使用者的電腦的連線回應
