LDAP: smbldap-populate error

初始資料庫時，下了 # smbldap-populate 結果出現以下的錯誤訊息，找了很久，在網路上搜尋了很久也沒有結果，雖然知道是驗證方面出了問題，但是不知道哪裡錯了？因為每個相關檔案都檢查無誤。最後，發現的原因真是令人噴飯。解決方法在文章最底部！ Use of uninitialized value in substitution (s///) at /usr/lib/perl5/vendor_perl/5.8.8/smbldap_tools.pm line 135, line 73.

Switch Hub Crash I Switch Hub 突然當掉了

With a teacher research program and the use of SQL call, suddenly the network is interrupted. Ping DNS Server and Firewall do not get reply. The first reaction is: firewall was crash again! (Last week, an unknown crash) Go to the mainframe to reboot the firewall, but not solve the problem, watch the firewall log and found some session will suddenly coursing through and error. Suspect a client of LAN be got virus and cause the Internet paralysis; DNS Server reopened after it opened. But good times never often, is only for 1 minutes. Originally guess: "The catch virus PC users should not use the Internet, thus shutdown, the Internet has returned to good" Waiting for a 20 minutes still no improvement, at time has ping any servers with no replies. Why all of the servers? Even if the network traffic congestion, at least there will be the occasional one or two reply correct. Then suddenly to a telephone conversation, reminded "Maybe the switch hub that connect all the servers was crashing?" It's right, all reopened were get after switch hub reboot. However, why switch hub crash for no reason at all? -------- 下午正與某位老師研究SQL的使用以及程式的呼叫，突然網路都斷線了。Ping DNS和防火牆卻得不到Reply回應，第一個反應就是：防火牆又掛了！(上星期才不明的掛了一次) 到了主機房再重開防火牆，沒有解決問題，進防火牆看日誌檔，發現某些session會突然飆高且error，懷疑是區域網路中有一台Client中毒了，而造成網路癱瘓；重開DNS Server之後卻通了。只是，好景不常，只通了一分多鐘。本來猜測："中毒的PC使用者應該是覺得網路不能使用了，因而關機，所以網路又恢復順暢，等他在關機就好了。"等了一、二十分鐘還沒有改善，這時候已經Ping不到任何一台Server了，為什麼會Ping不到全部的Server呢？就算網路塞車，至少也會有偶爾的一、二個reply才對。這時突然來了一通電話，提醒了"會不會是串接所有主機的Switch Hub掛掉了？" 果然，重開Switch Hub一切就恢復正常了。可是，為什麼無緣無故Switch Hub會掛掉呢？

Set Powers for One Document of One Person | 設定網域單一資料夾給某人權限

A teacher said he did not enter his own folder, the folder when the double click will show "You do not have this folder competence." Checked it, the original folder authority is being replaced by others, and as long as add his account with write, read, execute can be. 1, Sign in by Domain\Admins. 2, On the folder, right-click and select "Content." 3, "Safety "-->"Add New." 4, "Advanced "-->" Immediately Find "-->" join the domain account "-->"OK." 5, Granting authority, please note that do not check "Full Control". Full Control may cause Domain\Admins can not manage the folder, if the people leave, they must use other methods to loot the authority. -------- 某個老師說他不能進他的資料夾，當雙鍵該資料夾時，會出現"您沒有此資料夾權限"。查了一下，原來是資料夾權限被換成其他人了，只要加他的帳號及修改、讀取、執行權限即可。 1、以Domain\Admins的身分登入。 2、在該資料夾上點擊滑鼠右鍵，選擇"內容"。 3、"安全性"-->"新增"。 4、"進階"-->"立即尋找"-->"欲加入權限之帳號"-->"確定"。 5、給予權限，請注意，請勿在"完全控制"上打勾。完全控制有可能造成Domain\Admins未來無法管理該資料夾，如果該人離職，就必須另外用方法取回權限。
