Common FTP, FTPS & SFTP Error Codes and What They Mean
When working with file transfer protocols like FTP, FTPS, and SFTP, servers send and receive various return codes during sessions. Some codes indicate successful file transfers, while others signal errors and require further action. And when things go wrong, understanding the meaning behind the sever return codes can save you and your team time, money and frustration.
Generally the larger our systems get, the more of an administrative burden they become. More user accounts need creating for access; permissions and controls need to be set correctly for security purposes; and something or someone needs to keep a track of the changes taking place.
When it comes to old technology lurking around in your network, there is as good a chance as any other that an FTP or SFTP server is part, having been a staple of most IT teams for a very long time.
