openwrt 直接 web 界面升级成功后，网络已经可以访问，但是 ssh 登陆的时候貌似账号密码不对，telnet 直接无法连接，这是怎么回事？要如何解决？

[TheCure]

删除~/.ssh/known_hosts

[Jays]

重来一次 ， 我的到货后一天重刷了4次

[nonozone]

@Jays 怎么重来...升级完是没有web界面的...
@callofmx win系统

实在不想碰维护模式啊...

[jemyzhang]

密码和你web界面的密码是一样的

[nonozone]

@jemyzhang 我知道...我把所有的密码都试过了...

[hellov22ex]

一旦设定了密码后telnet自动失效，只能ssh链接上去，我用的是Xshell4链接的，账号密码为你web页面的登陆账号密码，即root和密码

[ooxxcc]

把ssh的提示贴出来

我猜是因为主机公钥改变导致客户端拒绝连接

[nonozone]

@ooxxcc 输入密码的被拒绝。

[nonozone]

@ooxxcc

root@debian ~# ssh [email protected]
[email protected]'s password:
Connection to 192.168.10.1 closed.

[nonozone]

如果用putty打开的时候，输入账号root之后，提示输入密码，输完，窗口就自动关闭了。

[ooxxcc]

@nonozone ssh -4Cv试试……感觉是没跑起来shell？奇怪

[ooxxcc]

@nonozone 1.密码是对的，2.不是路由器公钥的问题，不清楚怎么一回事

[MerlinYang]

putty能记录所有返回信息，看下

[nonozone]

@MerlinYang 记录在哪里？哪个文件？反正输入密码，putty直接 关闭了。

[nonozone]

@ooxxcc 这样

[ooxxcc]

ssh过程是正常的，不过路由器上的shell坏了似乎……其他不清楚了

[nonozone]

@ooxxcc 那要咋办？只能维护模式强制重置密码了么？

[aboutboy]

这个问题我这两天刚接触 openwrt 也遇到了。刷机后如果遇到 ssh 输入正确的密码却无法登录的情况，可以重启一下路由器，再 ssh 就可以了。具体原因我还没找到。

[pennguo]

网页登录用户名和密码都设置 root，路由器断电，重启后 SSH 就可以登陆啦。（记得用网页登录用户名和密码）
