ssh 登录旧设备的问题解决

 

ssh登录一些老旧设备，出现以下问题：

问题：Unable to negotiate with 192.168.xx.xx port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1

解决：-oKexAlgorithms=+diffie-hellman-group1-sha1

问题：Unable to negotiate with 192.168.xx.xx port 22: no matching host key type found. Their offer: ssh-dss

解决：-oHostKeyAlgorithms=+ssh-dss

问题：Unable to negotiate with 192.168.xx.xx port 22: no matching cipher found. Their offer: 3des-cbc

解决：-oCiphers=+3des-cbc

 

最后命令是这样的：

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithms=+ssh-dss -oCiphers=+3des-cbc [e-mail]
