Changelog

21/11/2007 == version 0.2.5 ==

• Added mergeNodes() function to allow the fusion of two nodes during pair-wise alias resolution phases.
• Fixed a bug causing PingRR alias resolution technique to fail when the TTL value for the destination is underestimated.
• Fixed another bug causing false positives using PingRR alias resolution technique for some destinations on the same subnet of the Hynetd host.

20/11/2007

• Substituted gethostbyaddr() function with thread-safe getaddrinfo() function

19/11/2007

• Fixed a bug causing domain names to be permanently truncated at a fixed size

18/11/2007

• Now links obtained from SNMP not belonging to a /30 or /31 subnet are filtered out.

22/06/2007

• Added a conflict control during subnet creation using SNMP information. In some cases erroneus netmasks obtained by SNMP cause the creation of wide subnets (like '/16') that heavily compromise the accuracy.

04/06/2007

• The number of SNMP queries sent to each node is now minimized exploiting the key ip address part of the OID name. A new version of the snmpGetNext() funcion, called snmpGetNextE(), has been created.

25/05/2007

• Now SNMP queries filter out all local and INADDR_ANY addresses and all related fields in multi-column tables. Also the association of different fields of the same row is done in a safer way

22/05/2007

• Debug file couples.log is now created only in debug level 2 and bigger. This file can be really large, so check disk space before enabling it.

18/05/2007

• Fixed a bug in backtrace algorithm involving TTL counter switching from forward to backward mode
• Fixed a bug involving max TTL value causing segmentation fault in some cases
• Modified Makefile to permit debug mode (with debug levels) activation without modifications to the file. Now to enable it just type: make debug=1

10/05/2007

• Added install and uninstall targets to Makefile

28/03/2007

• IP addresses involved in a serial link now are forced to be router and are added to router list

23/03/2007

• Added the function CleanRouters to eliminate hosts from router list

16/03/2007 == version 0.2.4 ==

• Reorganized package folders
• Added -P option to simply execute ping toward each IP address belonging to given ranges (Useful to quickly estimate # of active addresses)

01/02/2007

• Added a more efficient heuristic to discover serial links using ICMP data. Now a "-l" option is available to switch from old method to the new one.
• Moved alias resolution between addresses with the same (not NULL) precHopRR from link reconstruction to aliasing phase 1

24/01/2007 == version 0.2.3 ==

• Fixed a bug causing segmentation fault during output generation
