  3. portmon.c: removed goto which was causing core dumps with certain compilers.

nocol v4.2 (Jul 1998)

  1. New monitors: apcmon, ntpmon, syslogmon, radiusmon
  2. Completely new web interface
  3. New logstats in perl

nocol v4.0 (Dec 1994)

  1. New monitors: etherload, hostmon, rpcpingmon, snmpmon
  2. New 'logstats' report generation script from the logs.
  3. Fixed update_event() to do log when the *severity* changes also, not just look at the state (up/down). Reason being that if an event has multiple severity thresholds, then one would also like to know when the event has got out of critical (it could still be in error/warning state, but its not Critical anymore).
  4. Added 'nocol_startup' library routine for consistent handling of signals and generation of config filenames. Cleaned up lot of common code in all monitors.
    IMPORTANTLY the config filename for 'ippingmon' is NOT 'ipnodes' anymore, but 'ippingmon-confg'.
  5. Bug fixes in noclogd, utility scripts, event_to_logstr, nocollib.pl, Makefiles, netconsole, etc.
  6. Display changed to 'netconsole' instead of netmon.

nocol v3.1 (Feb 1, 1994)

  1. 'multiping' considerably enhanced. Compiles on BSDI/386 systems now.
  2. Bugs fixed in nsmon, bcmp() in multiping, portmon, nsmon, eventselect, netmon/filter.c
  3. Changed all of fgetline() to fgetLine() to avoid stdlib conflicts.
  4. Typecast all malloc() statements. Function types defined in snmplib/mib.c and snmplib/parse.c to avoid compiler warnings.
  5. Added a nocol 'unit' field in trapmon (was NULL) to avoid messing up awk scripts.
  6. Added '-s' silent option in netmon.
  7. Moved version.h into include/ directory and included in 'nocol.h'.
  8. Fixed inet_ntoa() bug in tpmon/tpmon.c
  9. Fixed bug in the CMU code in cmu-snmp/snmplib/asn1.c
