On server initialization, all known interfaces are registered to xdmcp. Normally there would be at least two other entries with ifname = eth0. The error seems to be in a cygwin ioctl function. The code which calls t is in os/access.c and is (roughly) this. int fd = fopen("/dev/ip",O_RDWR, 0); ifnet.ib_next=1; while (ifnet.ib_next) { str.ic_cmd = IPIOC_GETIPB; str.ic_dp = (char *) &ifnet; ioctl(fd,I_STR, &str); } In some cases, the ioctl will only work for the loopback device. Maybe some of those who are familar with the cygwin network code can give me a hint. > get_xdmcp_sock: binding xdmcp socket to addr 192.84.36.146:0 > winDetectSupportedEngines () - Windows 95/98/Me > winDetectSupportedEngines () - DirectDraw installed > winDetectSupportedEngines () - Returning, supported engines 00000003 > winSetEngine () - Using Shadow DirectDraw > winCreateBoundingWindowWindowed () - WindowClient width 1018 height 714 > winInitVisualsShadowDD () - Masks: 00007c00 000003e0 0000001f bpRGB: 5 > winInitVisualsShadowDD () - Returning > > Fatal server error: > XDMCP fatal error: Session declined No valid address > > In case this helps in getting the problem fixed ...
