They are each very, very, different, even if the FTP interface is the same to make it easier for end-users to be force-switched to the encrypted versions. People mix up sftp, ftps and plain ftp all the time. ![]() Actually, if it were me, I'd rename that group to sftp-users to prevent confusion. If this is for 1 person, then there's no need to setup an ftp-users unix group. In general, for minimal security, it is best to never allow end-users to see the directory where their uploads go, then to do some processing on those uploads to ensure they don't contain malware before making them available to others in a download directory. Is that your intention? That comes from the directory permissions where the files are located. So, those permissions allow anyone in the ftp-user's group to delete any files. Fortunately for me, I don't deal with MSFT anymore. Probably need to find a how-to for the specific program to be used that explains how to setup ssh-keys and move the public key to the remote server. Further, I don't know if the built-in ssh from MSFT will work with WinSCP or Filezilla, which are the best sftp clients on that platform. However, MSFT decided **not** to include ssh-copy-id, so that will need to be handled manually. Win10+ has ssh-keygen and it works the same as on Linux. Do you already understand 80+% of Unix file permissions? If you need help with permissions, much more data will need to be provided. Https:///showthread.8#post13959278Īnd don't forget fail2ban and firewall settings: Can't hurt to try and if it doesn't work, relax the limitations for a few minutes to get the public-key uploaded, then lock it back down for sftp-only access again. ![]() I've never done this without having full ssh enabled, so I don't know how it works inside a chroot with only sftpd enabled. This makes all ssh-based connections, including sftp, hassle free AND more secure.įrom any Unix-based client, run these to commands to create a key, put the 2-halves (pub/private) in your ~/.ssh/ directory on the client, then the 2nd command will push the public ssh-key to the remote system, place it in the correct location and setup the permissions as required. If you have ssh-agent (or whatever key-management your client machines use) on your client, then you'll only need to "unlock" the ssh-keys once per login. If you don't want to be asked for login credentials, then you can setup ssh-keys between the client and the host. X11Forwarding noAnother question, when I'm trying download/upload it is asking again for password.Ĭan I remove this?Great that you got it working. Subsystem sftp /usr/lib/openssh/sftp-server spells out how to accomplish the chroot you seek with the openssh sftp server. Fail2ban will firewall block after more than 3 or 5 failed attempts from the same IP address. I always install the metapackage "ssh" and "fail2ban" to get both the ssh client and server programs. You can force more security by allowing only ssh-key/cert based authentication for logins too. If that's your intention, then you don't need chroot.īut if you care about security, then using sfp-server built-into the "openssh-server" package is what you want. The only way plain FTP makes sense is if you intend to share everything on the system with the entire world. If you've installed ssh, then there is an sftp-server included with instructions on how to setup a chroot for each user login. Plain FTP shouldn't be used since around 2002. those coming from MS-Windows) haven't been told this, I suppose.
