我打开了两个具有相同 cookie 和机器的 Erlang IPv6 节点，但是当我使用 net_adm：ping 命令时，它们无法连接。但是，当我打开两个具有相同 cookie 和机器的不同 IPv4 节点时，它们可以连接。erlang 版本是 21.1.3。Linux 操作系统是 Centos7。
以下是我的操作系统关于 IPv6 的设置
sysctl -a | grep ipv6 | grep disable
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.bond0.disable_ipv6 = 0
net.ipv6.conf.bond0/801.disable_ipv6 = 0
net.ipv6.conf.bond0/805.disable_ipv6 = 0
net.ipv6.conf.br-DYMAN1.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.docker0.disable_ipv6 = 0
net.ipv6.conf.ens12f0.disable_ipv6 = 0
net.ipv6.conf.ens12f1.disable_ipv6 = 0
net.ipv6.conf.ens4f0.disable_ipv6 = 0
net.ipv6.conf.ens4f1.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0
net.ipv6.conf.ovs-system.disable_ipv6 = 0
net.ipv6.conf.virbr0.disable_ipv6 = 1
net.ipv6.conf.virbr0-nic.disable_ipv6 = 0
以下是我的试验。
