每分钟都有一条日志，每个用户名都摘取几条，这些都是企图暴力登录的日志？

本地用git init --bare example.git 的简单方式搭建了几个git仓库，用户用git
git:x:1005:1005::/home/git:/usr/bin/git-shell
使用了 git-shell，禁止密码登录了，还加了相关规则，安全上应该能做的都做了，.
(详细见我以前总结的 http://tech.wutianqi.com/blog/2013/12/21/set-up-a-private-git-server-simply/ )

看监听端口也只有sshd, nginx, sendmail的端口，很好奇为啥会吸引别人来尝试用户gitolite， gitosis 这些来尝试登录？难道还能扫描到我系统里有git仓库？

sshd

user

invalid
