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)
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.
