Online/OneProvider 服务器 Debian 10 系统配置/开启 IPv6

发现Debian 10的系统，按照官方的教程用DHCP客户端获取IPv6地址，一直获取不到...

openwrt/odhcp6c

一、安装odhcp6c

echo "deb http://httpredir.debian.org/debian experimental main" >> /etc/apt/sources.list
apt-get update
apt-get install odhcp6c

二、编辑interfaces文件vim /etc/network/interfaces，添加内容

iface eno1 inet6 static
        address  IPv6段
        netmask  掩码长度
post-up odhcp6c -P 64 -c DUID串 eno1 -d
post-up ip -6 a a IPv6段/掩码长度 dev eno1

IPv6段/掩码长度以及DUID串，是发工单问OneProvider客服要。

三、编辑其他文件

编辑local文件vim /etc/modprobe.d/local.conf，修改或者添加内容

options ipv6 disable=0

编辑modules文件vim /etc/modules，添加如下字符

ipv6

编辑sysctl文件vim /etc/sysctl.conf，添加以下内容

net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=1
net.ipv4.icmp_echo_ignore_broadcasts=1
net.ipv4.conf.default.forwarding=1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
net.ipv6.conf.eno1.autoconf=0
net.ipv6.conf.eno1.accept_ra=2
net.ipv6.conf.default.forwarding=1
net.ipv6.conf.all.forwarding=1
net.ipv6.conf.default.proxy_ndp=1
net.ipv6.conf.all.proxy_ndp=1

四、重启服务器

reboot

ip a

会输出

blabla
2: eno1
blabla
 inet6 2001:xxx:xxxx:xxx::/64 scope global 
       valid_lft forever preferred_lft forever
blabla

尝试ping

ping6 ipv6.google.com
PING ipv6.google.com(par10s39-in-x0e.1e100.net (2a00:1450:4007:807::200e)) 56 data bytes
64 bytes from par10s39-in-x0e.1e100.net (2a00:1450:4007:807::200e): icmp_seq=1 ttl=119 time=1.04 ms
64 bytes from par10s39-in-x0e.1e100.net (2a00:1450:4007:807::200e): icmp_seq=2 ttl=119 time=5.73 ms

五、小记

很多步骤不太确定是否必要，但用以上的步骤成功获取到IPv6。后面再好好学习下各个步骤的具体用处！
