VSFTPD sees old mount --bind
Hi guys,
Our company sells a product that has two servers than run in a pair--for the part I explain below the two systems run independently.
On both servers I did the following. I used the mount --bind command. to allow the FTP user to see the contents of another directory. I found an easier to way to accomplish what I wanted. Removing the mount -- bind, rysnc was used in the crontab to constantly mirror the two directories. My manger did not like that. He said I should use the user on the system to access the directory that has the files the client wants. Rysnc's were removed from the crontabs. On the second server everything works great using FTP and SFTP--client can get into the correct home directory and sees the right files.
However on the first server the client is getting into what is the /var/ftp directory. WinSCP lists the home directory properly in the header but the listing is incorrect--it shows the files of /var/ftp. However when I check the home directory on the first sever the directory listing is correct. Home directory is correct, shell is set to /bin/bash in the /etc/passwd file. Permissions are the same on both (Before they were different but I fixed that but the problem stayed.)
I am stumped. Any ideas what I should be looking for? I did not chroot anything either and like I said, the second server works fine. What would make winscp list the contents of /var/ftp?

NAME
mnt - attach to 9P servers
SYNOPSIS
#M
DESCRIPTION
The mount driver is used by the mount system call (but not bind; see bind(2)) to connect the name space of a process to the service pro-
vided by a 9P server over a communications channel. After the mount, system calls involving files in that portion of the name space will
be converted by the mount driver into the appropriate 9P messages to the server.
The mount system call issues session and attach(5) messages to the server to identify and validate the user of the connection. Each dis-
tinct user of a connection must mount it separately; the mount driver multiplexes the access of the various users and their processes to
the service.
File-oriented system calls are converted by the kernel into messages in the 9P protocol. Within the kernel, 9P is implemented by procedure
calls to the various kernel device drivers. The mount driver translates these procedure calls into remote procedure calls to be transmit-
ted as messages over the communication channel to the server. Each message is implemented by a write of the corresponding protocol message
to the server channel followed by a read on the server channel to get the reply. Errors in the reply message are turned into system call
error returns.
A read(2) or write system call on a file served by the mount driver may be translated into more than one message, since there is a maximum
data size for a 9P message. The system call will return when the specified number of bytes have been transferred or a short reply is
returned.
The string is an illegal file name, so this device can only be accessed directly by the kernel.

BUGS
When mounting a service through the mount driver, that is, when the channel being multiplexed is itself a file being served by the mount
driver, large messages may be broken in two.
