在xshell下用ssh登录远程主机centos出现以下问题:

Connection established.

To escape to local shell, press 'Ctrl+Alt+]'.

Connection closed by foreign host.

之前用xshell远程登录centos都是可以的, 就在我重装了openssh-server后出现这问题, 于是我猜这可能是ssh配置文件/etc/ssh/sshd.conf的问题

编辑ssh配置文件/etc/ssh/sshd.conf:

# vim /etc/ssh/sshd.conf

找到下面的 X11Forwarding yes, 将其改为no或在前面加#注释即可。

X11Forwarding设置是否允许X11转发

#AllowAgentForwarding yes
#AllowTcpForwarding yes
#GatewayPorts no
#X11Forwarding no
X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes
#PrintMotd yes
#PrintLastLog yes
#TCPKeepAlive yes
#UseLogin no
#UsePrivilegeSeparation yes
#PermitUserEnvironment no
#Compression delayed
#ClientAliveInterval 0
#ClientAliveCountMax 3
#ShowPatchLevel no
#UseDNS yes
#PidFile /var/run/sshd.pid
#MaxStartups 10:30:100
#PermitTunnel no
#ChrootDirectory none

重启ssh服务:

# service sshd restart
