安裝ucarp（支援IP的動態替換）

libpcap ( must be installed on your system, with
development files (headers).

假設你的版本是：libpcap-1.2.1.tar.gz

tar -zxf libpcap-1.2.1.tar.gz

cd libpcap-1.2.1

./configure

configure: error: your operating system's lex is insufficient to compile libpcap. flex is a lex replacement that has many advantages, including being able to compile libpcap. for more information, see

.

如果你linux沒安裝bz2的解圧程式，那先安裝

tar -zxf bzip2-1.0.6.tar.gz

cd bzip2-1.0.6

sudo make install

安裝完成之後，解壓 flex-2.5.37.tar.bz2

tar -jxvf flex-2.5.37.tar.bz2

cd flex-2.5.37

./configure

出現如下錯誤

checking for m4 that supports -p... configure: error: could not find m4 that supports -p

去安裝好m4之後，安裝flex成功

再安裝libpcap

所有的這些都安裝好，libpcap總算安裝好。

我的版本是1.5.2

安裝，應該沒什麼問題了。

執行

/usr/local/sbin/ucarp

提示錯誤：

/usr/local/sbin/ucarp: error while loading shared libraries: libpcap.so.1: cannot open shared object file: no such file or directory

經過驗證，發現libpcap.so.1在/usr/local/lib下

執行以下命令

sudo cp /usr/local/lib/libpcap.so.1 /usr/lib

再執行ucarp

搞定

談談UDX對多IP的支援

現在很多機房提供雙線，三線或四線伺服器，雖然有很多硬體解決方案，但是對於我們遊戲開發公司來說，或多或少要對多ip進行支援。udx在這方面也提供了解決方案。udx可以對多個ip port進行繫結，從而提供多ip的支援。而繫結了多個ip的udx物件即是對多個ip提供相同的服務，同時對於這個udx的所有客...

IP位址的動態分配

相對於靜態分配 bootp 而言，動態分配 dhcp 不僅提高了ip位址的利用率，還能夠節約有限資源。dhcp 動態主機配置協議使伺服器能夠動態地為網路中的其他主機提供ip位址，而且可以不給intranet 內聯網中除dhcp dns和wins伺服器外的任何伺服器設定和維護靜態ip位址。使用dh...
