Release Notes: Manual sending of NetFlow v.9 template refreshes is now supported. ICMP type/code is now encoded into port numbers, similar to some Cisco products. Lower-resolution tracking of flows (ignoring port or protocol information) was implemented for high-bandwidth users. Several small but important bugfixes were made.
Release Notes: This release adds support for NetFlow export to multicast group addresses. There are several bugfixes.
Release Notes: This release added IPv6 flow tracking and NetFlow v.9 export support.
Release Notes: This release added NetFlow v5 export format to softflowd and the sample Perl NetFlow collector.
Release Notes: This version now drops privileges and chroots to an empty directory, reducing potential impact of any vulnerabilities. It improves the supplied Perl NetFlow collector, adding more useful output and IPv6 listen support. It also improves performance, adds a separate timeout for ICMP traffic, adds support for exporting flows to an IPv6 host, adds preliminary Solaris 9 support, and fixes many bugs.
Release Notes: This release fixes some bugs in fragment handling which could cause some flows to not be correctly accounted.
Release Notes: This release fixes compilation on systems with strange libpcap variants, as well as for a crash caused by use-after-free.
Release Notes: A remote control interface (softflowctl), fast-expiry of finished TCP flows, improved manpages, support for BPF filters, and a fair number of bugfixes.
