ssh免密登錄失效處理

目錄

• 解決方法

免密登錄設置完成了,ssh連接其他服務器能免密成功,但是在某個服務器上一直不成功,每次都必須輸入密碼

使用 -vvv 查看日志: ssh -vvv 用戶@ip # ssh連接時顯示日志

debug3: send_pubkey_test
debug3: send packet: type 50
debug2: we sent a publickey packet, wait for reply
debug3: receive packet: type 51

debug3: authmethod_lookup password
debug3: remaining preferred: ,password
debug3: authmethod_is_enabled password

解決方法

A服務器連接B服務器,在B服務器上修改:

# 修改文件
sudo vi /etc/ssh/sshd_config

# 設置StrictModes 為no
#StrictModes yes
StrictModes no

# 重啟服務
sudo service sshd restart
