I am looking for a good free SFTP system for *nix. I need to be able to create accounts with segregated access to individual folders.
Here is the detail...
We currently have an FTP server which all the support engineers use very often to move files from DAD to the FTP server and visa versa. The cannot be copied directly from the RDP session. In addition to this the engineers drop files on the FTP server for clients to retrieve. Engineers also send config backups of their clients to the FTP server. As this is a client facing solution we as a security organisation cant be seen to be using a non secure protocol such as FTP.
There are many free flavours of SFTP which basically only allow you to send files over SFTP to the root folder on the SFTP server with full rights to the root folder. We require the ability to create files for clients with certain permissions that will for example allow a client to drop files on the server but not rename or delete them. In addition to this the client will only see his folder as opposed to all the other folders on the SFTP server based on his username and password.
