SNMP as device support in EPICS:

• Presentations:
  
  • Original devSupport for SNMP was developed by Richard Dubney at LANL
    This is his PPT presentation in Epics Workshop 2004 in Santa Fe.
    
  • Our current installation was presented by Albert Kagarmanov
    
    This is our PDF presentation in the Epics Workshop 2005 in Arshamps (France)
    
  
  
  
• Sources for download:
  
  • 0-1) This is the original devSNMP source code
  
  
  
  • 1-00)This is an improved version of devSNMP source for download, organized as a single epics iocApplication (obsolete)
  
  
  
  • 1-01)This is a patched version of 1-1) with proper Counter32 support for longin-record (see README in destribution)
  
  
  
  • 1-02)This is a patched version of 1b) with a small change of the Posix Thread Stack Size
  
  
  
  • 1-03)This is a patched version of 1-1) with using epicsThreadGetStackSize(epicsThreadStackBig) for Posix Thread Stack Size calculation as it was discussed in Epics Tech-Talk (http://www.aps.anl.gov/epics/tech-talk/2006/msg01277.php)
  
  
  
  • 2) DESY startup directory for softIOC with a set of MIB-oriented DB-files
  
  



• Before you start:
  
  • current devSNMP supports only snmp-read commands, which probably is not so bad because of network security reasons.
    
    
  • it's better to ask your network administrator about using SNMP in a "production"-network -- snmp, as a lot of another unix-open standards (ftp,smtp, telnet,etc), is not 100% secure, it's better to use it i.e. behind a firewall.
    
    
  • You should decide first which version of SNMP you would like to support (SNMPV1 SNMPV2c SNMPv3). Current devSNMP works with SNMPv2c. It must be compatible with V1 and V3 but when we started we had a lot of problems with some hosts which supports SNMPv1 only.
