ftp-scp
SFTP (Secure File Transfer Protocol) is the transfer protocol to view and transfer files over SSH. SFTP works the same as FTP but is encrypted.
SFTP Advantages
- Encrypted
- Nothing extra to install (such as FTP server)
- Works like any other FTP server
- Compatible with the popular clients such as Filezilla and WinSCP
- You can login to any SSH accessable Linux user.
How to use SFTP
- Connect like any FTP except it uses the port (default 22)
- Use your linux username / password
- You might need to set protocol to SFTP in your FTP client.
Bad practice to avoid
By all means, you should never
- 1.Connect to a server as root.
- 2.Use FTP if SFTP is available.
Root login to an FTP
Here is why you shouldn't
- By logging in as root, you might accidentally remove essential system files or put useless files into the wrong place and mess up with your system.
- But even more annoying, any file you'll write will belong to root, and the user won't be able to either read, change, or execute writtent files as root.
- FTP is an unencrypted protocol, therefore it is very unsecure to edit sensitive files using it.
How to operate without root FTP login ?
- If you need to edit system config files, then do like everyone else : use an SSH text editor like "nano" or "vi".
- Set your FTP so that you can login as users with a valid shell from the machine. Eventually, disable root FTP login.
- Oh, one more thing... Did we talk about SFTP ?
