我记得最近的事情是将软硬内存锁 ulimit 更改为无限制。现在我无法通过 ssh 进入机器。
这是 ssh 日志。

在发布到这里之前,我已经尝试了以下失败的方法:
尝试通过 Norc noprofile 登录 ssh user@host 'bash --noprofile'
强制使用 tty ssh -t user@host
移动了 bash_profile。尝试通过 sshing ssh user@host
。
重命名limits.conf
文件,希望它不会被读取。
重新启动 ssh 服务器。
通过knife
as运行命令knife ssh "name:server" "come_command"
ssh user@host 'ulimit -l 64'
, ssh user@host 'ulimit -S -l 64'
, ssh user@host 'ulimit -H -l 64'
,ssh user@host 'exec ulimit -H -l 64'
我不确定这种运行命令的方式 inline: 是否ssh user@host "some_command"
有效,因为我无法获得简单的目录列表。我也尝试通过重新启动ssh user@host 'reboot'
但不认为该命令已执行。我也从 AWS 重新启动了机器,但没有成功。
尝试 ssh 是失败的原因吗?有什么办法可以通过 ssh 进入服务器吗?

我遇到了类似的问题,我似乎只看到以下奇怪的消息:
client_input_channel_req: channel 0 rtype exit-status reply 0.

我试图ssh
进入的用户没有默认 shell。
我运行了以下命令:
chsh -s $(which sh) username
Run Code Online (Sandbox Code Playgroud)
然后我就能够了ssh
。
笔记:
运行su username
返回退出代码1
(失败),现在它可以正常工作了。
