ubuntu – 无法通过SSH连接到服务器 – “服务器拒绝分配pty”

我有一个运行Ubuntu 10.10的STRATO V-PowerServer用于我的东西,但最近有问题通过ssh连接到服务器.

基本上我只有ssh访问服务器,如果有必要,我可以启动到恢复模式,我的所有东西都在/修复,以便我可以在系统上做任何修复.

问题是,当我尝试通过ssh连接到服务器时,我收到此错误：

Using username "florian".
[e-mail]'s password:
Server refused to allocate pty
Linux hwn36335 2.6.18-028stab070.5 #1 SMP Fri Sep 17 15:37:23 MSD 2010 i686 GNU/Linux
     Ubuntu 10.10

                 Welcome to Ubuntu!
                                    * Documentation:  https://help.ubuntu.com/
                                                                              /home/florian/.zlogin:1: command not found: display_info

因此shell无法打开,我无法输入任何命令.我已经尝试谷歌“服务器拒绝分配pty”但找不到任何有用的东西,尽管此问题已经发生在其他人之前.另外,我有时甚至会得到一个不同的错误：“通道0上的pty分配请求失败”而不是其他错误.对于这个问题我只能发现：

但不幸的是它没有帮助……

有没有人知道为什么会出现这个错误以及我可以尝试修复它？

如果你能给我提示,那会很棒.我知道一些基本的东西,知道如​​何使用我的服务器,但如果它深入解决问题,我就在我的极限…… ;-)谢谢！

你试过重新创建pty和tty设备吗？

[e-mail]:~# /sbin/MAKEDEV tty
[e-mail]:~# /sbin/MAKEDEV pty

它似乎是虚拟服务器上的一个已知问题……

如果您无权访问任何shell,可以尝试通过ssh发送命令：

florian@localmachine:~$ssh [e-mail] "/sbin/MAKEDEV tty"
florian@localmachine:~$ssh [e-mail] "/sbin/MAKEDEV pty"

编辑反映您的评论：

如果你使用chroot,你还必须挂载/ proc,/ dev和/ sys：

root@h1696522:/# mount -o bind /proc /repair/proc
root@h1696522:/# mount -o bind /dev /repair/dev
root@h1696522:/# mount -o bind /sys /repair/sys

它现在应该工作.
