SUSE Linux 10 SP2 关闭IPV6及防火墙

部分一：关闭ipv6# ip add sh1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 brd 127.255.255.255 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever2: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0c:29:7b:80:9b brd ff:ff:ff:ff:ff:ff inet 172.24.0.20/24 brd 172.24.0.255 scope global eth1 inet6 fe80::20c:29ff:fe7b:809b/64 scope link valid_lft forever preferred_lft forever由上面的标识可知，当前系统的ipv6已经启用了，那么现在要将ipv6关闭：# vi /etc/modprobe.conf将“alias net-pf-10 ipv6”修改为如下：alias net-pf-10 offalias ipv6 off然后重启系统，一定要重启系统才能看到效果。# ip add sh1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 brd 127.255.255.255 scope host lo2: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0c:29:7b:80:9b brd ff:ff:ff:ff:ff:ff inet 172.24.0.20/24 brd 172.24.0.255 scope global eth1 部分二：使用命令永久关闭防火墙
（1）首先查看当前防火墙的状态linux:~ # SUSEfirewall2 statusSuSE系统会默认启用防火墙的，而且防火墙中默认存在很多规则。此时可以用下面命令立即关闭防火墙：linux:~ # SuSEfirewall2 stopSuSEfirewall2: Warning: ip6tables does not support state matching. Extended IPv6 support disabled.SuSEfirewall2: batch committing...SuSEfirewall2: Firewall rules unloaded.（2）上面的操作只是确定当前系统已经关闭了防火墙，但不确保系统重启后仍然是关闭防火墙的，所以还要进行下面的操作：linux:~ # chkconfig --list | grep -i fireSuSEfirewall2_init 0:off 1:off 2:off 3:off 4:off 5:off 6:off B:on SuSEfirewall2_setup 0:off 1:off 2:off 3:on 4:on 5:on 6:off于是：linux:~ # chkconfig SuSEfirewall2_setup offlinux:~ # chkconfig --list | grep -i fireSuSEfirewall2_init 0:off 1:off 2:off 3:off 4:off 5:off 6:off B:on SuSEfirewall2_setup 0:off 1:off 2:off 3:off 4:off 5:off 6:offlinux:~ # chkconfig --level B SuSEfirewall2_init offlinux:~ # chkconfig --list | grep -i fireSuSEfirewall2_init 0:off 1:off 2:off 3:off 4:off 5:off 6:offSuSEfirewall2_setup 0:off 1:off 2:off 3:off 4:off 5:off 6:off至此，系统的防火墙完成关闭了。实体环境中配置Android项目Ubuntu开发环境指南SUSE Linux 10 SP2创建本地yast数据源相关资讯 suse
