Low Voltage Vontrol Applications

MPOD Low Voltage Crate Control

SNMP Driver from NCSL

I got a generic EPICS SNMP driver/device support from John A. Priler (priller@nscl.msu.edu) called snmp-nscl-0.9.8. It was their version of the SNMP driver which apparently they originally obtain from DESY. They actually used this package for MPOD crate control. He also sent me an example of an EPICS database file which use the SNMP device support.

I was able to compile the snmp-nscl-0.9.8 for 32-bit RHEL5 Linux. But compilation of 64-bit Ubuntu 10.04 failed because of some syntax error:
