我想创建一个匿名 ftp。用户只能从 pub 目录上传和读取。操作系统是Unixware 71，ftp服务器是WU-FTPD。这是 ftpaccess 文件
#ident "@(#)unixsrc:usr/src/common/cmd/cmd-inet/usr.sbin/in.ftpd/ftpaccess /main/1"
#
# ftpd configuration file, see ftpaccess(4tcp).

这是具有 home/ftp 权限和所有者的目录

服务器正常工作，我可以以匿名方式将文件“cast”上传到服务器上。但正如您所看到的，无法读取（如果您知道文件名，则可以获取）

找到解决方案在其他论坛上 我必须在 chroot ftp 中复制共享库。
mkdir -p /home/ftp/usr/lib
cp /usr/lib/libc.so.1 /home/ftp/usr/lib
