System administrators use SSH utilities to Use -t when you want to run a terminal-oriented program such as htop, and -T when you want a "clean" 8-bit channel for transferring binary data. Learn about key options, authentication, port forwarding, and more. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e. . when implementing menu services. -t dsa|rsa Selects the type of the key. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e. Discover key options for enhancing security and efficiency.
