Acme Evil

Because of the recent mail server was hacked and I also FreeBSD wake unable to make the best management, therefore take this opportunity to move Mail Server to Fedora Core 6. Previously prepared to put the work in advance is create all of the user accounts of FreeBSD in FC6. But no one should create account one by one! After all, the units have nearly 200 people Account. Therefore, due to this Webmin installed a suite, so we can export substantial account:

Login the FreeBSD system which own webmin service --->System---> Users and Groups --->Export users to select batch file--->Select the users and their options --->Export NOW

Login Fedora Core 6's webmin--->System --->Users and Groups--->Create, modify and delete users from batch file --->Browse you file---> select the set options --->Execute batch

Waitting implementation of the batch file .... . Done! ^ ^

This preparatory work is finish! Finish a "major event"!

Next, should the FreeBSD mail and mail folders of user home directory (because it was installed the openwebmail) transfer to FC6 (I use is that I want, is probably the most stupid way. .)

In FreeBSD :

#cd var * FreeBSD because my mail is under the /var

#tar zcvf mail.tar.gz mail/

*Entire mail folder compressed into one of tarball

# mv mail.tar.gz /var/www/html/ *moved to the web underground

# cd / * under /

#tar zcvf home.tar.gz home/ *all user home folders under /home

#mv home.tar.gz /var/www/html/ *moved to the web underground

Fedora Core 6 :

#cd /

#wget http : //freebsd.domain/home.tar.gz

*Catch FreeBSD's home directory file backup

#tar zxvf home.tar.gz

*decompress home.ta r.gz. This will directly cover the original home
directory file name all the same file or folder

#rm -rf home.tar. gz * Remove have already decompress off tarball

#cd /var/spool *to mail stored in the folder on the floor

#wget http://freebsd.domain/mail.tar.gz *FreeBSD's mail backup file.

#tar zxvf mail.tar.gz *decompress mail backup file

#rm -rf mail.tar.gz *delete the mail.tar.gz has been used.

Don't forget to back to FreeBSD to delete the files that are homr.tar.gz and mail.tar.gz under the website root directory! Otherwise, people can download arbitrary your backup file is, of course, your web servers are the starting. Now almost completed. YA!

最近因為Mail Server常被入侵，而且FreeBSD我也不熟，無法作最好的管理，於是趁此機會要將Mail Server移到Fedora Core 6上。

先前要準備的工作事先把FreeBSD上的使用者帳號在FC6上在重建一次，但應該沒有人會一個一個來重建吧！畢竟我們的單位也有將近兩百人的帳號。於是，因本身有安裝Webmin此一套件，所以我們可以把帳號大量匯出：

登入 FreeBSD的webmin--->系統--->使用者與群組--->Export users to batch file--->選好要匯出的使用者及其選項--->Export NOW

登入 Fedora Core 6的webmin--->系統--->使用者與群組--->使用批次檔一次過建立/修改/刪除使用者--->Browse你會出的檔案--->--->選好要設定的選項--->執行批次檔

Waitting.....Done! ^^

這樣先前的準備工作就做完了！做完一件”大事”了！

接下來要把FreeBSD上的mail及家目錄裡的mail資料夾（因為有裝openwenmail）轉移到FC6上（我用的是我想得到的方法，可能是最笨的方法。@.@）

在FreeBSD端：

#cd /var *因我的bsd的mail是放在/var/mail底下

#tar zcvf mail.tar.gz mail/ *把整個mail資料夾壓縮成一個tar.gz的壓縮檔

# mv mail.tar.gz /var/www/html/ *移到網頁目錄底下

# cd / *到 / 底下

#tar zcvf home.tar.gz home/ *所有人的家目錄在home底下

#mv home.tar.gz /var/www/html/ *一樣移到網頁目錄底下

Fedora Core 6上：

#cd /

#wget http://freebsd.domain/home.tar.gz

*把FreeBSD上所有人的家目錄備份檔抓過來

#tar zxvf home.tar.gz

*解開home.tar.gz，此會直接覆蓋原來家目錄裡所有檔名相同的檔案或資料夾

#rm -rf home.tar.gz *刪除已經解開過的壓縮檔（不解開就是暫空間而已）

#cd /var/spool *到FC6上存放mail的資料夾的上一層

#wget http://freebsd.domain/mail.tar.gz

*把FreeBSD上的mail備份檔抓過來
#tar zxvf mail.tar.gz *解開mail備份檔

#rm -rf mail.tar.gz *刪除已經用過的mail備份檔

記得回到FreeBSD上把網頁根目錄下的home.tar.g及mail.tar.gz都刪掉喔！不然別人是可以任意下載您的備份檔的，當然是您的網頁伺服器有開的情況下。

至此差不多就完成了！。
