I should have said specifically that this is Luke Pascoe's work.
Looking through the code, the program expects owfs to be mounted on
/var/1wire and logs to /tmp/1wire_snmp.log
These are easily changed constants in the first few lines.
The code is also very nicely commented.
I might suggest that a version that uses owserver (via the ownet protocol)
would also be a very flexible approach. Then the snmp server wouldn't even
have to run on the same machine.
