WebNMS SNMPUtilities is a collection of utilities written in Java, the most useful of them might be MIB Browser. It allows to you to connect to a SNMP service and browse it in a graphical interface. You can load custom MIBs in it.
The problem with it is that it uses, by default, its own internal Java Runtime Engine (JRE) that is old and 32 bit. It doesn’t work on x86_64, it gives an error like this:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/user/bin/WebNMS/SNMPUtilities/jre/lib/i386/xawt/libmawt.so: Can't load IA 32-bit .so on a IA 32-bit platform
This can be solved by configuring it to use the 64 bit openJDK that is included in openSUSE.
Edit the first line of the file SNMPUtilities.sh, change the value of the variable JAVA_HOME to this:
Now you can run ./SNMPUtilities.sh. Choose from the menu Options/Settings/General. There you have a field JAVA_HOME where you must enter the same value as above.
