I just installed FC3 for the first time. When I ssh onto that box (from am FC1 box), there is a longish pause and then I see: Warning: No xauth data; using fake authentication data for X11 forwarding. I've googled this but found no understandable answer. Apparently, this involves xauth but I cannot grok it's man page. I'd like to prevent the delay and if there is a security problem, I'd like to close it. I'd also like to use X11 forwarding. Previously, IIRC, I didn't have to do anything special to enable X11 forwarding. But now when I try to run an X program during the ssh session, I get: [amead@alan ~]$ xcalc Xlib: connection to "localhost:10.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key Error: Can't open display: localhost:10.0 Any advice would be appreciated. I don't know much about X. -Alan
