I have just reinstalled WebMO on our linux system running RH7.2. When using it from the same computer where it is installed (and where the server runs), everything works fine. When trying to use the web interface from a different computer, login screen displays properly, but when I attempt to log in a message is displayed "Network connection refused by the server 127.0.0.1. The server may not be attempting connections or may be busy." Error log of the apache server produces the following message: "File does not exist: /var/www/html/webmo/java/javax/swing/JApplet.class"
I would really appreciate any help with this problem.

First off, the error in the apache error log is nothing to worry about. This is just the Java applet attempting to detect if Swing (Java 1.2) is installed.

The real problem is most likely a WebMO and or Apache setting. WebMO attempts to determine the name of the webserver (usually the hostname of the webserver, but it may be different if you are using virtual hosts) using the SERVER_NAME environmental variable set by Apache. It then uses this webserver name to create URLs in the future.

It sounds like WebMO is determining that the name your webserver is 127.0.0.1 (localhost), probably because this is what Apache is returning in the SERVER_NAME environmental variable. This causes problems when you try to access WebMO from another computer, because localhost then refers to the client rather than the server.

There are two easy ways to remedy this. Either

1) Edit the WebMO configuration file (globals.int), located in the webmo/cgi-bin interfaces subdirectory. Change the 'webserver' variable from 'autodetect' to the hostname or ip address of your webserver.

2) Or edit your Apache configuration file (/etc/httpd/conf/httpd.conf) and change the option 'UseCanonicalName' to 'Off' (which seems to be the default for RH 8.0 and most other distros, but not RH 7.2 evidently).

Thank you very much for your help, I have changed the Apache configuration file as you have suggested and now everything is working.
