Thanks! I can access my ancient desktop machine using ssh from the prototype Gentoo box. I can even run full facility Emacs from it. I can't, as yet, access the laptop from my desktop box. No doubt, some simple modification (such as creating a non-root user on the laptop) will make it work. Or do I need to install an ssh-daemon on the laptop? Anyhow, the ssh idea was so brilliant, I'm wondering why I didn't think of it myself. ;-) Thanks! -- Alan Mackenzie (Nuremberg, Germany).

The X Window System has always worked seamlessly over > the network (i.e., since before KVM switches were invented). In the last several years many software distributions have chosen to invoke the X11 server with the "-nolisten" argument, which disables some of the visible network functionality. This is an extra layer of "security." I have been inconvenienced by this practice a couple times, such as when I want to be remote from both the server and the display. [Three machines: mine, the server, the display: ssh a.b.c.d "DISPLAY=e.f.g.h:3 /path/to/client" where screen 3 at ip4 e.f.g.h has the client display and pointer (mouse), the program is running on ip4 a.b.c.d, and I have stdin+ stdout+stderr but no login account on the machine with the display. This is quite some fun, particularly when client is a debugger such as gdb!] >> I want something that works on a remote virtual terminal. > > ssh works for me (perhaps with screen). Or "ssh -Y" if forwarding an X11 connection. -- |
