| | | | | | | in a packet header and the computed checksum for the data that the checksum covers, what the checksum field's value should have been. Use that routine in the IP printer.

| | | | | | | purpose of 1.105 was to print the ip header values (len, ttl, tos) at the beginning of the line (where it belongs to) and not at the end; it is only displayed using the -v(erbose) options; the BGP output (where i am working now on) gets much more cleaner now;
* split BGP output to multiple lines;hannes2002-07-141-34/+32
| | | | | | | added support for Originator_ID, Cluster List Attributes; reworked BGP Open Message Decoder do decode optional Capabilities; fixed the NEXTHOP decoder of MP_REACH and MP_UNREACH to honor NH length based on AFI,SAFI

* From Crist J. Clark <cjclark@alum.mit.edu>: print the IP protocol fieldguy2001-10-271-4/+16
| | | | | | | | for fragments other than the first fragment. Also, for packets whose IP protocols we don't handle ourselves, print the protocol name if "getprotobynumber()" finds it, otherwise print the protocol number.
* Eliminate some unused parameters.fenner2001-09-171-3/+3
| | | | | | | | | | | Use const more. Use EXTRACT_* macros more. Use TCHECK* more. Use tok2str() to replace some home-grown workalikes. smb: - Get rid of private types, use tcpdump-defined types - Rename fdata and fdata1 to smb_fdata and smb_fdata1 to avoid conflict with IRIX library function.

| | | | | | | | padding info are in the last fragment but the header is in the first fragment. Pass padding length back to IP to allow trimming the padding. Update in_cksum() prototype to allow using it for checksums including the pseudo-header.
* Remove #if 0 sectionsfenner2001-06-151-45/+1
| | | | | | | | Finish converting over to having the caller print the IP address (except for UDP, TCP and SCTP). This consists mostly of removing places where the IP address is printed, both in the big "case" in ip_print() and in the individual printers. Also fix a couple of spacing bugs.
* added explicit protocol number to "ipip" - John Hawkinson <jhawk@MIT.EDU>mcr2001-05-291-2/+2

* SCTP printing from Armando L. Caro Jr. <acaro@mail.eecis.udel.edu>fenner2001-05-091-2/+10
| | | | | Modified to print IP/IPv6-level addresses like TCP does, and to not print multi-line detail unless -vv by fenner.

| | | | | | | | | | | 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".

| | | | | Pointed out on BUGTRAQ on 16 Jun 1999 (reported as infinite loop on Linux and core dump on all other OS's)
* * print-rt6.c: make IPv6 routing header printing work with new 2292bisitojun1999-12-221-5/+5
| | | | | | | | | | | API. * print-bgp.c: improve options printing. ugly code exists for unaligned option parsing (need some fix). * const poisoning in SMB decoder. * make dump format back to original. someone may want to add an option to do ascii printing, but keep the default behavior as is for scripts used in many places. * -Wall -Werror clean checks.
* Eliminate printf format warnings.fenner1999-12-151-6/+6
| | | | | Don't use len without initializing in ip_printts() (in the case of an invalid type).
* IGMP fixes:fenner1999-11-231-27/+21
| | | | | | | - Identify IGMPv1 and IGMPv2 instead of "report" and "nreport". - Don't use questionably-portable bitfields for packet formats. - Don't try to check the IGMP checksum if the packet was not completely captured.
