apache下htaccess的Invalid command 'AuthUserFile'错误
使用了apache的 .htaccess做身份认证后, 无法访问
查看日志报错如下:
"Invalid command 'AuthUserFile', perhaps misspelled or defined by a module not included in the server configuration"
google 一下, 在apache配置文件里加入如下配置
LoadModule auth_basic_module /usr/lib/apache2/modules/mod_auth_basic.soLoadModule authz_owner_module /usr/lib/apache2/modules/mod_authz_owner.soLoadModule authn_file_module /usr/lib/apache2/modules/mod_authn_file.so
ok，问题解决

netstat -n | awk '/^tcp/ {++state[$NF]} END {for(key in state) print key,"\t",state[key]}'
会得到类似下面的结果，具体数字会有所不同：
LAST_ACK 1
SYN_RECV 14
