Tecnologia simplificada - Access with FTP/FTPS


You can access your Storage Box by using FTP. Please use your assigned hostname <username>.sersi.mx, username, and password. FTP connections are unencrypted; only FTPS (FTP+TLS) connections are encrypted.

If you also plan on using a sub-account on your Storage Box, please make sure to also use the sub-account username for the connection.

Active and passive modes

FTP protocol is built upon two connections: the first connection, via port 21 for all commands, and the second, for the transfer of all file content. The second connection can be differentiated into active and passive modes.

With the active mode, the ftp server attempts to establish a connection to the client (server -> client). However, this can be blocked with the client's firewall, and a timeout may occur. As a solution to this problem, you can use the passive mode.

With the passive mode, a connection is built from the client to the server (client -> server). The method for activating the passive mode differs between different client programs. For that reason, you should check your program's help guides.
