内网ssh连接速度慢的问题解决
内网ssh连接服务器速度突然变慢,需要很久才能连接上,执行命令打开-v调试开关,发现有下面提示:
debug1: Next authentication method: gssapi-with-mic
debug1: Unspecified GSS failure. Minor code may provide more information
Cannot determine realm for numeric host address
网上搜索发现是由于dns解析出问题造成的,解决方式,
1. 修订resolve.conf 中dns服务器地址,换成正常速度快的
2. 关闭ssh连接时的dns解析,这里修改/etc/ssh/ssh_config 文件,关闭GSSAPI方式认证
GSSAPIAuthentication no
