When X appears to start but Mosaic complains that the URL cannot be found,
it is an indication that the Web server (httpd) has not started. Using the
OpenWindows menu, start an xterm and use the <ps -aux | grep httpd> command
to verify that the server is not running. Edit the
/etc/httpd/conf/httpd.conf file. Uncomment the following line:
#ServerName new.host.name
In addition, you can change the entry <new.host.name> to a name of your
choice. Save the file and start the Web server with the <httpd -x> command.
To gain access to the X configuration pages, push the reload button within
Mosaic or restart Mosaic.
G10.e. Why do I get a "connection reset by peer" error message when I open a
local xterm window and try to rlogin to another system?
Try setting the TCP/IP control panel (the one for Open Transport) to "Load
Only When Needed". (You can get to this by clicking the "Options..."
button).
G10.f. Whenever X is running, the entire system is unstable, whether I'm
using MacTCP clients or X exclusively. Is there a configuration that will
make things more stable?
Get all updates (XTen users should upgrade to 6.0.1+). If this doesn't help,
try taking the TCP/IP control panel out of the Control Panels folder. On
some systems, this can greatly help our dealings with OpenTransport.
