X Login via XDMCP over anything !
I'd just like the apparently more simple, but still unachievable (to me) functionality of having MacOSX's server issue an XDMCP on startup to another machine, and thereby having the remote machine starting an XDM session on it . . .
X Login via XDMCP over anything !
eXodus 9.0 can do this with ease. It's got really nice XDMCP (not to mention SSH) support. (Unfortunately, it doesn't have Apple's really nicely accelerated Xquartz server, so I don't use eXodus anymore.)
XDMCP/XDM support (or lack thereof) is really one of the major weaknesses of Apple's X11.app compared to other X11 implementations, whether they be on other Unices/Linux or other Mac-based products such as eXodus. Something else that stinks - it seems like Apple likes to drop things from 3rd-party releases that are still useful, even on a Mac. The 10.3 version of X11.app drops a lot of documentation - in /usr/X11R6/lib/X11/doc there's only a bunch of HTML files (in .../html) now - compared to, say, XDarwin 1.1, where there used to be a whole raft of stuff, including XDMCP documentation:
I have no clue why Apple dumped all this documentation when they released their own version of XFree86 4.3.0 in X11.app. (That said, doing XDM is still tricky - even if you read the xdm(1) man page and get it fired up properly on your remote Mac, there are still gotchas - one gotcha I can recall is trying to connect to an XDM server at work over our VPN, but finding that the remote XDM server was trying to route the return packets to the original local IP address rather than the VPN-assigned local address, which wasn't working - we were blocking all outbound connections to port 6000 with a destination IP address outside of our Class B address space. Apparently the XDMCP packets being sent from the local end were tagged with the "real" IP address instead of the VPN-assigned local address. So the return packets went off to never-never land and the XDM connection failed ... ) |
