I can follow what the article says but one thing I am unclear about is now on system boot the BIND process in the chroot jail will start since it the owner will no longer be root but some other user. Can... (1 Reply)

Good day. I currently have a request to have sftp access to a specific directory for a user(s). They can have access to that folder only, and nothing below it.

chroot
CHROOT(2) BSD System Calls Manual CHROOT(2)NAME
chroot -- change root directory
SYNOPSIS
#include <unistd.h>
int
chroot(const char *dirname);
DESCRIPTION
Dirname is the address of the pathname of a directory, terminated by an ASCII NUL. chroot() causes dirname to become the root directory,
that is, the starting point for path searches of pathnames beginning with '/'.
In order for a directory to become the root directory a process must have execute (search) access for that directory.
If the program is not currently running with an altered root directory, it should be noted that chroot() has no effect on the process's cur-
rent directory.
If the program is already running with an altered root directory, the process's current directory is changed to the same new root directory.
This prevents the current directory from being further up the directory tree than the altered root directory.
This call is restricted to the super-user.
RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate an error.
ERRORS
chroot() will fail and the root directory will be unchanged if:
[ENOTDIR] A component of the path name is not a directory.
[ENAMETOOLONG] A component of a pathname exceeded {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters.
[ENOENT] The named directory does not exist.
[EACCES] Search permission is denied for any component of the path name.
[ELOOP] Too many symbolic links were encountered in translating the pathname.
[EFAULT] Path points outside the process's allocated address space.
[EIO] An I/O error occurred while reading from or writing to the file system.
SEE ALSO chdir(2)WARNINGS
There are ways for a root process to escape from the chroot jail.
HISTORY
The chroot() function call appeared in 4.2BSD.
