Hi all, (This may actually be a question for the dtach people). I've recently been using dtach (basically the detach function of screen) over SSH to instruct my freeBSD machine to perform long tasks even after I disconnect from it. It's worked great: I run SSH and connect to my box, execute dtach to create a new session in which to execute a program, hit ctr-\ to detach the session from the terminal, and then I can close the SSH tunnel. Recently, I figured to do this with portupgrade. Now, I don't allow root login, so I log in as a user in the wheel group and use su. Now, as root, I run: dtach -A portupgrade -a. It starts working, but extremely slowly. For instance, "portsnap fetch update" takes several minutes, whereas it normally is blazing fast when performed locally. I can still detach, exit root, and close the SSH tunnel. I suppose this is probably a dtach performance issue? If anyone has any thoughts, I'd definitely appreciate them. Thanks! Sincerely, -- Ned Ruggeri
