* Add SIGINFO handler from LBLfenner2001-07-041-13/+42
| | | | | The rest of the low-level print-*.c handlers need the infodelay wrapping too.
* exit value field has to be positive. from netbsd (or do we want to return 255?)itojun2001-06-241-2/+2

* Add support for NetBSD DLT_PPP_ETHER; adapted from NetBSD changes byguy2001-06-201-1/+4
| | | | | | | | | Martin Husemann <martin@netbsd.org>. Clean up PPPoE dissector - get rid of unused variable, and have it just use its first argument as a pointer to the PPPoE packet (which may also make it work if, for example, you have PPPoE packets wrapped inside VLAN headers).

* Add support for a new link layer type DLT_LINUX_SLL, for use when doingguy2000-12-211-1/+4
| | | | | | | live captures with a "cooked" (SOCK_DGRAM) rather than a "raw" (SOCK_RAW) PF_PACKET socket; it includes a bunch of the fields from the "struct sockaddr_ll" you get in a "recvfrom()", including the Ethernet protocol field.
* Handle DLT_NULL correctly - the AF_ value is in host byte order, whichguy2000-12-161-1/+4
| | | | | | | | | | | | | | | | | | | | | may not be *our* byte order if we're reading a capture file from another machine; we currently handle that by checking whether it looks like an integer < 65536 or not and, if it's not, byte-swap it. This also lets us handle OpenBSD DLT_LOOP as well - it's like DLT_NULL except that the AF_ value is in *network* byte order. (Old-style Linux loopback captures were also DLT_NULL, but the header had an Ethernet type in it; there have also been captures where the header was a PPP header. For now, we just continue to assume that all DLT_NULL packets are IP, and check the IP version field to decide whether it's IPv4, IPv6, or something else. We may want to consider adopting Ethereal's heuristics, which would at least mean we wouldn't be reporting bogus packet types for old-style Linux loopback captures and those weird PPP - ISDN4BSD? - captures, although the version of libpcap that goes with this version of tcpdump doesn't produce bogus DLT_NULL captures for Linux loopback devices.)
* Allow tcpdump to work with earlier libpcaps.fenner2000-12-091-1/+7
| | | | (Tested with libpcap-0.4 as comes with FreeBSD 3.4)
* Get rid of the PCAP_ENCAP_ values - if an application uses them, thatguy2000-10-121-59/+14
| | | | | | | | | | | | | | | | | | application won't build with any other version of libpcap, which means that a lot of applications won't use them. In addition, "pcap_linktype()" needs to return DLT_ values, so that platforms that build libpcap as a shared library won't break binary compatibility if they update to this version of libpcap. Instead, we map from DLT_ values to LINKTYPE_ values when writing savefiles, and map from LINKTYPE_ values to DLT_ values when reading savefiles, so that savefiles don't have platform-dependent DLT_ values in the header as the link type, they have platform-independent LINKTYPE_ values. This means we don't need to make DLT_ATM_RFC1483, DLT_RAW, etc. have platform-independent values starting at 100 - only the values in the savefile header need to be like that.
* Get rid of includes of <netinet/in_systm.h>, and replace "n_short",guy2000-09-291-2/+1
| | | | "n_long", and "n_time", defined in that file, with other types.
* Add an "ip.h" header, to declare the IP stuff needed by dissectors, andguy2000-09-231-2/+1
| | | | | | | | | | | have dissectors include them rather than <netinet/ip.h> or <netinet/ip_var.h>, if they actually need that stuff. Put the declarations of the ICMP stuff directly into "print-icmp.c". Remove all unnecessary includes of <netinet/ip*.h> files. Copy the byte-order stuff from "nameser.h" into "tcp.h".
* Add support for NetBSD DLT_PPP_SERIAL (PPP in HDLC-like framing, as perguy2000-09-181-2/+7
| | | | | | | RFC 1662, or Cisco point-to-point with HDLC framing, as per seciont 4.3.1 of RFC 1547; there's always an address and control octet at the beginning of these packets, but they're not necessarily 0xff 0x03), which we map to PCAP_ENCAP_PPP_HDLC.
* Use the new PCAP_ENCAP_ codes rather than the corresponding DLT_ codes;guy2000-09-171-16/+56
| | | | | also use those DLT_ codes that older libpcaps may have used directly rather than mapped to PCAP_ENCAP_ codes, if they're defined.
* Add a token-ring link-layer dissector, made by merging the FreeBSD andguy2000-07-251-2/+2
| | | | | NetBSD ones; use it for DLT_IEEE802, which in many OSes is used for token ring.

* add print-ascii.c and print-telnet.c from netbsd.itojun1999-12-221-46/+17

* From: Juergen Schoenwaelder <schoenw@ibr.cs.tu-bs.de>mcr1999-12-131-2/+19
| | | | | | | | Here is a new version of the libsmi patch for tcpdump. It provides some bug fixes and some enhancements such as access checking and better range checking. The patch also fixed a few bugs in the print_snmp.c module of tcpdump itself (unrelated to the usage of libsmi).
