439 applications can tell the user they need to go play with permissions

586 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
588 New Linux libpcap implementation, which, in 2.2 and later
589 kernels, uses PF_PACKET sockets and supports kernel packet
590 filtering (if compiled into the kernel), and supports the "any"
591 device for capturing on all interfaces. Cleans up promiscuous
592 mode better on pre-2.2 kernels, and has various other fixes
593 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
594 doesn't show duplicate packets on loopback interface, etc.).
596 Fixed HP-UX libpcap implementation to correctly get the PPA for
597 an interface, to allow interfaces to be opened by interface name.
599 libpcap savefiles have system-independent link-layer type values
600 in the header, rather than sometimes platform-dependent DLT_
601 values, to make it easier to exchange capture files between
604 Non-standard capture files produced by some Linux tcpdumps, e.g.
605 the one from Red Hat Linux 6.2 and later, can now be read.
607 Updated autoconf stock files.
609 Filter expressions can filter on VLAN IDs and various OSI
610 protocols, and work on Token Ring (with non-source-routed
613 "pcap_open_dead()" added to allow compiling filter expressions
614 to pcap code without opening a capture device or capture file.
616 Header files fixed to allow use in C++ programs.
618 Removed dependancy on native headers for packet layout.
619 Removed Linux specific headers that were shipped.
621 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
624 Fixed bug that could cause subsequent "pcap_compile()"s to fail
625 erroneously after one compile failed.
627 Assorted other bug fixes.
629 README.aix and README.linux files added to describe
630 platform-specific issues.
632 "getifaddrs()" rather than SIOCGIFCONF used, if available.

649 the list of interfaces is read as necessary in order to hold the
652 Greg Troxel <gdt@ir.bbn.com>
