  •  21 Oct 2013 15:53

    Release Notes: An off-by-one bug in a safety check has been corrected. The bug did not affect scanlogd itself, but it may be a security issue in other projects reusing code from scanlogd. The license has been changed to heavily cut-down BSD.

    •  11 Mar 2006 14:10

      Release Notes: The source code has been modified to use sysconf(_SC_CLK_TCK) instead of CLK_TCK when _SC_CLK_TCK is known to be available or CLK_TCK is not (needed for glibc 2.3.90+).

      •  04 Jul 2004 01:28

        Release Notes: This release drops cleanup() because it was not async-signal-safe.

        •  03 Jun 2004 01:45

          Release Notes: scanlogd will now chroot to /var/empty to further reduce the impact of potential bugs in scanlogd itself and in the libraries that it uses. When built with libnids or direct libpcap support, a smart pcap filter expression is now used to hopefully filter out most uninteresting packets while in the kernel. Many minor code cleanups and other enhancements have been made, and RPM spec file and startup script for Red Hat Linux and compatible distributions are now included.

          •  10 Nov 2000 07:18

            Release Notes: This release improves support for libnids 1.14+.
