I just noticed that I couldn't ssh -X from a machine into a fully configured jail on the same machine and have an X app display back on the desktop. I think that this used to work, but I can't swear to it. I've been playing around, and now have pretty much everything on the machine stripped down. No jails, no ipfw, no interface aliases. It's running 5.4-STABLE as of a few days ago, and everything is compiled from ports and should be up to date. The video cards a matrox 550 and I'm running with mga_drv.o and mga_hal_drv.o from the mgadriver-4.1 tarball from the matrox site. It's dual headed w/ a pair of NEC Multisync LCD1850X's on a dual-headed DVI cable. It turns out that I can't ssh -X from that machine into any other machine and have it work. I can, however, ssh -X from another machine (e.g. 5.3BETA4 laptop) into it and display onto the laptop. In particular, it can't even ssh -X into itself and display an X app. There's some information at http://grapeape.alerce.com/screwball including netstat and /etc/rc.conf and an ssh -v -v -X session. If I ssh -X into itself and run xeyes, it just sits there. If I do a tcpdump -i lo0 from another window, there's a flood of traffic back and forth between the .ssh port and a variety of ports including .x11-ssh, one at 6011 [I think that the DISPLAY as localhost:11 that time around], and a bunch of other randomish. I've tried it with X11UseLocalhost on and off. At this point my eyes are crossed and I can't even figure out what to try next. And, I'm not feeling particularl bright, I'm sure it's going to turn out to be something obvious.... Anyone have any thoughts? g.home | help
