We recently built the Mit R2 tape on a Sun 3/140 running underr SunOS4.0. The Server works OK: It will display clients running on the local host, and on a remote Apollo (The Apollo clients were supplied pre- built by Apollo). Unfortunatley, Clients built on the Sun refuse to open displays other than "unix:0". The Clients make use of Xt and emit the following message when the "-display xxxx:0" option is used : X Toolkit Error: Can't Open display: xxxx:0 We have checked the obvious things including the -DTCPCOM in the XLib make file, and have disabled Host Access control. However, we have drawn a blank. Is this a common problem? Has anybody got any ideas? To put it another way HELP. Robin Heath .
