libtrace comes with a program (traceconvert) that lets you convert from any trace type that libtrace understands, to any trace type libtrace can output.

Example usage:

  traceconvert legacyatm:auck4-20010220-210122-0.gz pcapfile:auck4-20010220-210122-0.pcap.gz

Note: that the pcapfile: output specifier by defaults outputs compressed pcap files (which tcpdump can't natively understand). Use tcpdump -r <(zcat auck4-20010220-210122-0.pcap.gz) to read these files.

Conversions for common tracesets:

Auckland I

Libtrace does not currently support the DAG2 trace format. If you have a need for libtrace to understand the Auckland I or other DAG2 traceset then drop us a note and we'll add support.

Auckland II

Available from: ​http://pma.nlanr.net/Traces/long/auck2.html

  traceconvert legacyatm:auck2-20000125-143640-0.gz pcapfile:auck2-20000125-143640-0.pcap.gz

Auckland IV

Available from: ​http://pma.nlanr.net/Traces/long/auck4.html

  traceconvert legacyatm:auck4-20010220-210122-0.gz pcapfile:auck4-20010220-210122-0.pcap.gz

Auckland VI

Available from: ​http://pma.nlanr.net/Traces/long/auck6.html

There are two types of traces, some are ATM and some are Ethernet. for the traces ending in -0 or -1 use:

  traceconvert legacyatm:auck6-0.gz pcapfile:auck6.pcap.gz

for the traces ending in -e0 or -e1 use:

  traceconvert legacyatm:auck6-e0.gz pcapfile:auck6.pcap.gz

Auckland VII

Available from: ​http://pma.nlanr.net/Traces/long/auck7.html

These traces are an ERF timestamp followed by the first 4 bytes of the ATM header. These traces contain no IP headers. Libtrace cannot read these traces at the moment, if you need the ability to read them, then contact us.

Auckland VIII

Available from: ​http://pma.nlanr.net/Special/auck8.html

These traces are in standard ERF format.

  traceconvert erf:auck8-20031215-220000.gz pcapfile:auck8-20031215-220000.pcap.gz

NZIX II

Available from: ​http://pma.nlanr.net/Traces/long/nzix2.html These traces are in legacy ethernet format.

  traceconvert legacyerf:nzixII-20000710-000000.gz pcapfile:nzixII-20000710-000000.pcap.gz

Waikato tracesets

These traces are in standard ERF format

  traceconvert erf:waikato1-20050525-000000-0.gz pcapfile:waikato1-20050525-000000-0.pcap.gz
