用Ubuntu远程登录虚拟host时出现：
start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
解决：
sudo dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl
(此方法没试过。)
cmd='/usr/sbin/sshd',opts='-D'
host.cmd(cmd+' '+opts+'&')
意为在新建的虚拟Host的终端里执行/usr/sbin/sshd -D&，其中sshd -D&为启动sshd并作为一个非守护进程在后台运行。

出现错误：unable to access 'https://github.com/xxx/xxx.git: Failed to connect to github.com port 443‘原因是没有输入指定用户名和密码：打开终端，切换到git目录(我的是/home/steven/.git)sudo gedit config把url = https://github.com/xxx/xxx.gi
