Operating Systems Linux Red Hat SFTP user include/exclude without preventing SSH login Post 302784453 by jim mcnamara on Friday 22nd of March 2013 08:29:31 AM

Possibility:
OpenSSH has chroot functionality in current versions. On the type of subsystem. Basically you just need to add lines like below to your
Code:
/etc/ssh/sshd_config file.

Code:
Subsystem sftp internal-sftp

Match group sftpusers
     ChrootDirectory /var/www/someplace/safe
     X11Forwarding no
     AllowTcpForwarding no
     ForceCommand internal-sftp

Next create a group sftpusers with command
Code:
groupadd sftpusers

The last step is then to create a user belonging to group sftpusers:

Code:
useradd -g sftpusers -d /var/www/xy/backup/files username

restart your ssh service:
Code:
/etc/init.d/sshd restart

This only affects sftp access only. And users in the sftpusers group only.

/var/www/someplace/safe is completely your decision. All this is on the assumption that I understood what you want. What you presented seems an almost unworkable melange of stuff as is. So feel free to ignore this.

Net::SFTP::Foreign::Constants(3pm)			User Contributed Perl Documentation			Net::SFTP::Foreign::Constants(3pm)

NAME
Net::SFTP::Foreign::Constants - Constant definitions for Net::SFTP::Foreign SYNOPSIS
use Net::SFTP::Foreign::Constants qw(:tag SSH2_FILEXFER_VERSION); print "Protocol version is ", SSH2_FILEXFER_VERSION; DESCRIPTION
Net::SFTP::Foreign::Constants provides a list of exportable SFTP constants: for SFTP messages and commands, for file-open flags, for status messages, etc. Constants can be exported individually, or in sets identified by tag names. Net::SFTP::Foreign::Constants provides values for all of the constants listed in the SFTP protocol version 3 draft; the only thing to note is that the constants are listed with the prefix "SSH2_" instead of "SSH_". So, for example, to import the constant for the file-open command, you would write: use Net::SFTP::Foreign::Constants qw( SSH2_FXP_OPEN ); TAGS
As mentioned above, constants can either be imported individually or in sets grouped by tag names. The tag names are: :fxp Imports all of the "SSH2_FXP_*" constants: these are the constants used in the messaging protocol. :flags Imports all of the "SSH2_FXF_*" constants: these are constants used as flags sent to the server when opening files. :att Imports all of the "SSH2_FILEXFER_ATTR_*" constants: these are the constants used to construct the flag in the serialized attributes. The flag describes what types of file attributes are listed in the buffer. :status Imports all of the "SSH2_FX_*" constants: these are constants returned from a server "SSH2_FXP_STATUS" message and indicate the status of a particular operation. :error Imports all the "SFTP_ERR_*" constants used to represent high level errors: "SFTP_ERR_LOCAL_ALREADY_EXISTS", "SFTP_ERR_LOCAL_CHMOD_FAILED", "SFTP_ERR_LOCAL_OPEN_FAILED", "SFTP_ERR_LOCAL_READ_ERROR", "SFTP_ERR_LOCAL_STAT_FAILED", "SFTP_ERR_LOCAL_UTIME_FAILED", "SFTP_ERR_LOCAL_WRITE_FAILED", "SFTP_ERR_REMOTE_BAD_PACKET_SEQUENCE", "SFTP_ERR_REMOTE_BAD_PERMISSIONS", "SFTP_ERR_REMOTE_BAD_TIME", "SFTP_ERR_REMOTE_BLOCK_TOO_SMALL", "SFTP_ERR_REMOTE_CLOSE_FAILED", "SFTP_ERR_REMOTE_FSETSTAT_FAILED", "SFTP_ERR_REMOTE_FSTAT_FAILED", "SFTP_ERR_REMOTE_LSTAT_FAILED", "SFTP_ERR_REMOTE_MKDIR_FAILED", "SFTP_ERR_REMOTE_OPENDIR_FAILED", "SFTP_ERR_REMOTE_OPEN_FAILED", "SFTP_ERR_REMOTE_READDIR_FAILED", "SFTP_ERR_REMOTE_READ_FAILED", "SFTP_ERR_REMOTE_REALPATH_FAILED", "SFTP_ERR_REMOTE_REMOVE_FAILED", "SFTP_ERR_REMOTE_RENAME_FAILED", "SFTP_ERR_REMOTE_RMDIR_FAILED", "SFTP_ERR_REMOTE_READLINK_FAILED", "SFTP_ERR_REMOTE_SYMLINK_FAILED", "SFTP_ERR_REMOTE_SETSTAT_FAILED", "SFTP_ERR_REMOTE_STAT_FAILED", "SFTP_ERR_REMOTE_WRITE_FAILED" and "SFTP_ERR_REMOTE_HARDLINK_FAILED". Note: these constants are not defined on the SFTP draft. :ext Import all the "SSH2_FXE_*" constants: there are the constants defined for usage with SFTP extensions. Currently, these are supported: "SSH2_FXE_STATVFS_ST_RDONLY", "SSH_FXE_STATVFS_ST_NOSUID". There is one constant that does not fit into any of the tag sets: "SSH2_FILEXFER_VERSION", which holds the value of the SFTP protocol implemented by Net::SFTP::Foreign.
