环境

平台:阿里云ecs实例
系统:ubuntu22

问题经过

创建实例的时候我没有设置ipv6,并且使用了一段时间,云主机的ipv6是后面单独设置上去的,期间我在1panel上面设置了绑定ipv6,之后就发现当域名解析成ipv6时会连接失败,使用ipv4地址直接连接或者域名被解析成ipv4时可以连接成功,这个时候ssh并没有挂,后面我发现当配置文件只设置ipv4的监听没问题,设置ipv6就会挂掉,最后我添加AddressFamily any就没问题了,我今天重现不了这个问题了。

新问题(服务器重启之后)

现在的新问题是我只能设置ipv6,单独设置ipv4会挂

基本配置


# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

Include /etc/ssh/sshd_config.d/*.conf

# Set this to 'yes' to enable PAM authentication, account processing,

# be allowed through the KbdInteractiveAuthentication and

问题配置

只监听ipv4

PasswordAuthentication yes
ListenAddress 0.0.0.0
#ListenAddress ::

监听ipv4+AddressFamily

PasswordAuthentication yes
AddressFamily any
ListenAddress 0.0.0.0
#ListenAddress ::

无问题配置

不监听任何地址

PasswordAuthentication yes

监听所有ipv4+ipv6

PasswordAuthentication yes
ListenAddress 0.0.0.0
