FTP登录时错误信息500 oops的解决

郑全

FTP登录时错误信息：
500 OOPS: cannot change directory:/home/xxxxLogin failed.
421 Service not available, remote server has closed connection
开始以为是权限问题，将home/xxxx chmod为777，vsftpd配置文件全开依然不行。
百度一下查处原因：
==================================
I found information at the NSA that indicates you can disable SELinux protection of the ftp daemon.
setsebool -P ftpd_disable_trans 1
This seems a bit drastic. It certainly works for now though.
==================================
原来是新装系统RHEL5 增强的系统安全SELinux在作怪，关掉SELinux对FTP Daemon的保护就OK了：
# setsebool ftpd_disable_trans 1
# service vsftpd restart
