1.1 Maintaining a persistent connection - UNR-HPC/pronghorn GitHub Wiki

If you need your terminal session to stay persistent and able to suffer dropped connections it is recommended that you use tmux or screen utility once you have logged in to Pronghorn.

This will require you to note which login node you have logged into and SSH into that node directly instead of pronghorn.rc.unr.edu

Currently we have two login nodes available.

• login-0.ph.rc.unr.edu

• login-1.ph.rc.unr.edu

• tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached. When tmux is started it creates a new session with a single window and displays it on screen. A status line at the bottom of the screen shows information on the current session and is used to enter interactive commands.

• screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells). Each virtual terminal provides the functions of a terminal.
