转贴: 一、安装前准备 1.所需要软件包 linux-2.6.28.tar.gz kernel.org/pub/linux/kernel/v2.6/linux-2.6.28.tar.gz iptables-1.4.3.2.tar.bz2 [/url] netfilter-layer7-v2.22.tar.gz l7-protocols-2009-05-28.tar.gz 2.把以上内核和软件包解压到/usr/src下(这个是我个人的习惯) tar -zxvf linux-2.6.28.tar.gz -C /usr/src tar -zxvf netfilter-layer7-v2.22.tar.gz -C /usr/src tar -zxvf l7-protocols-2009-05-28.tar.gz -C /usr/src tar -jxvf iptables-1.4.3.2.tar.bz2 -C /usr/src 3.卸载系统自带的iptables rpm -qa | grep iptables 列出已安装的iptables包 rpm -e --nodeps ~~ 二、安装layer7 1.给新内核安装layer7补丁 cd /usr/src/linux-2.6.28/ patch -p1 < /usr/src/netfilter-layer7-v2.22/kernel-2.6.25-2.6.28-layer7-2.22.patch 2.编译新内核 2.1修改内核配置项 make oldconfig 全部保持默认 make menuconfig General setup ---> Prompt for development and/or incomplete code/drivers 必选 Networking ---> Networking options ---> Network packet filtering framework (Netfilter) ---> Core Netfilter Configuration ---> 该项下的所有项目建议都选上 Layer 7 debugging output 必选 IP: Netfilter Configuration ---> 该项下的所有项目必需都选上 2.2编译并安装新内核 make make modules_install make install 2.3 设置新内核为默认启动的内核,如果是远程连接服务器,必须要修改这项,否则重启后默认加载旧的kernel vim /boot/gurb/gurb.conf default=1 把1改为0 timeout=15 设置等候时间 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.28) root (hd0,0) kernel /boot/vmlinuz-2.6.28 ro root=LABEL=/ rhgb quiet initrd /boot/initrd-2.6.28.img title CentOS (2.6.18-164.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-164.el5 ro root=LABEL=/ rhgb quiet initrd /boot/initrd-2.6.18-164.el5.img 保存退出 reboot 3.编译安装iptables并支持layer7 cp /usr/src/netfilter-layer7-v2.22/iptables-1.4.3forward-for-kernel-2.6.20forward/*.* extensions/ ./configure --with-ksource=/usr/src/linux-2.6.28 make make install 4.安装l7协议 cd /usr/src/iptables-1.4.3.2/l7-protocols-2009-05-28 make install 5.测试 iptables -V 回显: iptables v1.4.3.2 iptables -m layer7 --help 回显: Usage: iptables -[AD] chain rule-specification [options] iptables -I chain [rulenum] rule-specification [options] iptables -R chain rulenum rule-specification [options] iptables -D chain rulenum [options] iptables -[LS] [chain [rulenum]] [options] iptables -[FZ] [chain] [options] iptables -[NX] chain iptables -E old-chain-name new-chain-name iptables -P chain target [options] iptables -h (print this help information) Commands: Either long or short options are allowed. --append -A chain Append to chain --delete -D chain Delete matching rule from chain --delete -D chain rulenum Delete rule rulenum (1 = first) from chain --insert -I chain [rulenum] Insert in chain as rulenum (default 1=first) --replace -R chain rulenum Replace rule rulenum (1 = first) in chain --list -L [chain [rulenum]] List the rules in a chain or all chains --list-rules -S [chain [rulenum]] Print the rules in a chain or all chains --flush -F [chain] Delete all rules in chain or all chains --zero -Z [chain] Zero counters in chain or all chains --new -N chain Create a new user-defined chain --delete-chain -X [chain] Delete a user-defined chain --policy -P chain target Change policy on chain to target --rename-chain -E old-chain new-chain Change chain name, (moving any references) Options: [!] --proto -p proto protocol: by number or name, eg. `tcp' [!] --source -s address[/mask] source specification [!] --destination -d address[/mask] destination specification [!] --in-interface -i input name[+] network interface name ([+] for wildcard) --jump -j target target for rule (may load target extension) --goto -g chain jump to chain with no return --match -m match extended match (may load extension) --numeric -n numeric output of addresses and ports [!] --out-interface -o output name[+] network interface name ([+] for wildcard) --table -t table table to manipulate (default: `filter') --verbose -v verbose mode --line-numbers print line numbers when listing --exact -x expand numbers (display exact values) [!] --fragment -f match second or further fragments only --modprobe= --set-counters PKTS BYTES set the counter during insert/append [!] --version -V print package version. layer7 match options: --l7dir (--l7dir must be specified before --l7proto if used) [!] --l7proto 至此安装过程完全完成 |
