使用Docker+host转发ssh时， gitpull/push有点卡卡的

实际体感整个过程时2-3秒左右， 看日志倒是很短
感觉到了服务端的时间比较长， 怀疑时ssh建立连接时间有点长了。

自己查了一下， 这种shim模式是要转git的用户login到宿主机。 我用的Ubuntu登录执行比较慢导致的。

解决方法是注释掉以下文件的2个session项目

/etc/pam.d/sshd

# Print the message of the day upon successful login.
# This includes a dynamically generated part from /run/motd.dynamic
# and a static (admin-editable) part from /etc/motd.
session    optional     pam_motd.so  motd=/run/motd.dynamic
