xshell每输入几个字母就断开连接怎么解决

xshell每输入几个字母就断开连接非常频繁显示如下

输入 vi /etc/ssh/sshd_config文件是空的

可能是和由于xshell工具重新连接设置有关，详细可参考

从上面文章中拷贝配置添加到当前编辑文本中

给你一个基本的，你编辑一下你的sshd_config文件，注意链接超时，主要是里面的参数keepalive，这个打开后设置，就不会断开了：

#GSSAPIKeyExchange no
#GSSAPIEnablek5users no

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# and ChallengeResponseAuthentication to 'no'.
# WARNING: 'UsePAM no' is not supported in Red Hat Enterprise Linux and may cause several
# problems.
