OnTheSSH supports uploading a file or directory to multiple remote hosts simultaneously, or downloading files or directories from multiple remote hosts at the same time.
On the left sidebar, click the checkbox to the left of the remote host name with the mouse (here, Ubuntu and 算法服务器 are selected), and then click the multi-host transfer button on the right
In the main page area, the selected remote hosts are displayed. Here, you can upload files or directories to both remote hosts simultaneously, or download files or directories at the same time.
When managing a cluster of servers with load balancing, multi-host upload is very useful, for example, when synchronizing a modified file to these servers. Multi-host download usage scenarios are relatively rare, such as when it is necessary to obtain the log files of all servers.
In the OnTheSS software, multi-host upload/download uses the SCP transfer protocol in SSH, and multi-host transfer manages multiple SCP transfers in one process. The following is the flowchart for multi-host upload/download:
Note: The SCP transport protocol does not have the capability to resume from breakpoints. Therefore, it is not recommended to send files that are too large in size, especially when the network is unstable.
