[FreeBSD] 取得 FreeBSD CVSUP 的更新狀態

FreeBSD CVS Site_1251699923593 (by appleboy46) 在 Sayya Joehorn 個人版看到有人實做出偵測台灣 CVSUP Server 更新狀態,以及更新的時間,也有程式碼的釋出,參考這篇:Script: 取得 FreeBSD CVSUP 的更新狀態,這篇寫的蠻清楚的,只需要 perl 跟 php 就可以完成,不過在使用過程有些事項必須要注意,在 FreeBSD 6.2 R 之後,已經內建了 csup 指令來更新 ports 或者是核心,所以要在另外安裝上 cvsup ports 套件,在 Perl 方面,也先裝 net/p5-Net-Rendezvous 才可以正確使用。
# 安裝必備軟體
cd /usr/ports/net/p5-Net-Rendezvous/ && make install clean
cd /usr/ports/net/cvsup-without-gui && make install clean
Perl 程式碼我有改過一些,不然沒辦法抓到正確資訊:

PHP 顯示部份,這邊就沒有動到,直接 copy 就可以

    Hi 關於 cvs-supfile 是copy /usr/share/examples/cvsup/ 下的example 還是得自己寫?

  • /usr/share/examples/cvsup/ 是給您參考的一些設定檔,您可以複製到想要放置設定檔的地方

    再去將裡面想要的設定 unmark 就可以了,或者是你要自己寫也可以啦。
