原文链接:统信UOS操作系统上禁用IPv6
hello,大家好啊!继之前我们讨论了如何在麒麟KYLINOS上禁用IPv6之后,今天我要给大家带来的是在统信UOS操作系统上禁用IPv6的方法。IPv6是最新的网络通信协议,但在某些特定的网络环境或测试场景中,可能需要禁用IPv6以确保兼容性或满足其他需求。本文将介绍在统信UOS上通过命令行的两种方式来禁用IPv6。让我们开始吧
注意事项
- 在进行系统配置更改之前,请确保您了解这些更改的影响,并考虑备份相关配置文件。
- 禁用IPv6可能会影响您的网络连接和某些依赖IPv6的应用程序或服务。
- 如果您不确定是否需要禁用IPv6,请咨询您的网络管理员或技术支持团队。
一、使用ipv6后的现象
1.查看系统信息
pdsyw@pdsyw-PC:~/Desktop$ cat /etc/os-version
[Version]
SystemName=UOS Desktop
SystemName[zh_CN]=统信桌面操作系统
ProductType=Desktop
ProductType[zh_CN]=桌面
EditionName=Professional
EditionName[zh_CN]=专业版
MajorVersion=20
MinorVersion=1060
OsBuild=11018.101.100
pdsyw@pdsyw-PC:~/Desktop$ uname -a
Linux pdsyw-PC 4.19.0-amd64-desktop #6108 SMP Wed Sep 13 13:27:25 CST 2023 x86_64 GNU/Linux
pdsyw@pdsyw-PC:~/Desktop$
2.ping网页查看,发现使用的是ipv6地址
pdsyw@pdsyw-PC:~/Desktop$ ping www.baidu.com
PING www.baidu.com(240e:e9:6002:15a:0:ff:b05c:1278 (240e:e9:6002:15a:0:ff:b05c:1278)) 56 data bytes

pdsyw@pdsyw-PC:~/Desktop$
3.使用ping -4 网页,使用的是ipv4地址
pdsyw@pdsyw-PC:~/Desktop$ ping -4 www.baidu.com
PING www.a.shifen.com (180.101.50.188) 56(84) bytes of data.
64 bytes from 180.101.50.188 (180.101.50.188): icmp_seq=1 ttl=50 time=52.5 ms

pdsyw@pdsyw-PC:~/Desktop$
4.查看网卡信息,wlp5s0上有ipv6的信息
pdsyw@pdsyw-PC:~/Desktop$ ifconfig
enp4s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 38:f7:cd:c4:72:9f txqueuelen 1000 (Ethernet)

pdsyw@pdsyw-PC:~/Desktop$
二、禁用ipv6的操作
方法一:编辑配置文件禁用ipv6
1.编辑/etc/sysctl.conf 文件,禁用ipv6相关信息
pdsyw@pdsyw-PC:~/Desktop$ sudo vim /etc/sysctl.conf
请输入密码:
验证成功
pdsyw@pdsyw-PC:~/Desktop$ grep disable_ipv6 /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
pdsyw@pdsyw-PC:~/Desktop$
pdsyw@pdsyw-PC:~/Desktop$ sudo sysctl -p
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
pdsyw@pdsyw-PC:~/Desktop$
2.查看网卡信息,wlp5s0上无ipv6的信息
pdsyw@pdsyw-PC:~/Desktop$ ifconfig
enp4s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 38:f7:cd:c4:72:9f txqueuelen 1000 (Ethernet)

TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 42 base 0xf000
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
loop txqueuelen 1000 (Local Loopback)
RX packets 35 bytes 3080 (3.0 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 35 bytes 3080 (3.0 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
wlp5s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.247 netmask 255.255.255.0 broadcast 192.168.0.255
ether 50:5a:65:c3:30:79 txqueuelen 1000 (Ethernet)
RX packets 248 bytes 58035 (56.6 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 244 bytes 32743 (31.9 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
pdsyw@pdsyw-PC:~/Desktop$
3.ping网页,使用的是ipv4地址
pdsyw@pdsyw-PC:~/Desktop$ ping www.baidu.com
PING www.a.shifen.com (180.101.50.242) 56(84) bytes of data.
64 bytes from 180.101.50.242 (180.101.50.242): icmp_seq=1 ttl=50 time=21.4 ms
64 bytes from 180.101.50.242 (180.101.50.242): icmp_seq=2 ttl=50 time=73.1 ms
64 bytes from 180.101.50.242 (180.101.50.242): icmp_seq=3 ttl=50 time=49.9 ms
^C
--- www.a.shifen.com ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 4ms
rtt min/avg/max/mdev = 21.373/48.149/73.129/21.168 ms
pdsyw@pdsyw-PC:~/Desktop$
4.重启系统
5.重启后网卡无ipv6信息
pdsyw@pdsyw-PC:~/Desktop$ ifconfig
enp4s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 38:f7:cd:c4:72:9f txqueuelen 1000 (Ethernet)

pdsyw@pdsyw-PC:~/Desktop$
方法二:使用sed命令禁用ipv6
1.使用sed添加禁用ipv6的信息
pdsyw@pdsyw-PC:~/Desktop$ sudo sed -i '$anet.ipv6.conf.all.disable_ipv6 = 1' /etc/sysctl.conf
请输入密码:
验证成功
pdsyw@pdsyw-PC:~/Desktop$ sudo sed -i '$anet.ipv6.conf.default.disable_ipv6 = 1' /etc/sysctl.conf
pdsyw@pdsyw-PC:~/Desktop$
pdsyw@pdsyw-PC:~/Desktop$ sudo sed -i '$anet.ipv6.conf.lo.disable_ipv6 = 1' /etc/sysctl.conf
pdsyw@pdsyw-PC:~/Desktop$
pdsyw@pdsyw-PC:~/Desktop$ sudo sysctl -p
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
pdsyw@pdsyw-PC:~/Desktop$
