Yesterday I installed two identical SuSE Linux Enterprise (SLES) 10 SP2 servers on their own private network. Since this private network was completeky isolated, neither server received any updates or patches. When I tried to connect from one server to the other through VNC at http://192.168.1.2:5801, I received the following message from Firefox:
Plugin Finder Service Window reports Firefox is now checking for available plugins
Click here to download plugin
I figured Firefox was trying to download the Java browser plugin from the Internet. I had not installed Java during the base installation, so this is what I did to fix the problem:
1) Downloaded the most recent version of Java, 1.6.0_07 available from http://java.com/en/download/manual.jsp
2) Copied jre-6u7-linux-i586-rpm.bin to /usr/src/packages/RPMs/i586
3) Opened a terminal and su root
4) cd /usr/src/packages/RPMs/i586
5) Typed chmod a+x jre-6u7-linux-i586-rpm.bin
6) To start install type ./ jre-6u7-linux-i586-rpm.bin
7) Hit the space bar several times to view license agreement
8) Press y to accept license agreement. Java will be installed to /usr/java/jre1.6.0_07
9) Link Java to plugin directory. To do this type cd /usr/lib/browser-plugins
10) Type ln -s /usr/java/jre1.6.0_07/plugin/i386/ns7/libjavaplugin_oji.so
Firefox was then able to see the VNC login screen at
http://192.168.1.2:5801
