NAME
tracediff - find and print differences between two traces SYNOPSIS
tracediff [ -m maxdiff ] firsturi seconduri DESCRIPTION
tracediff compares two trace files and prints the details of packets that differ to standard output. This is useful for finding packets that are present in one trace but not another or for finding conversion or snapping errors. -m maxdiff stop processing after displaying 'maxdiff' differences EXAMPLES
tracediff -m 10 erf:/traces/orig.erf.gz pcapfile:/traces/convert.pcap.gz BUGS
Not exactly a bug, but the contents of the framing headers (i.e. the PCAP or ERF encapsulation) are not compared. LINKS

NAME
tracesplit - split traces SYNOPSIS
tracesplit [ -f bpf | --filter=bpf] [ -c count | --count=count] [ -b bytes | --bytes=bytes] [ -i seconds | --seconds=seconds] [ -s unixtime | --starttime=unixtime] [ -e unixtime | --endtime=unixtime] [ -m maxfiles | --maxfiles=maxfiles] [ -S snaplen | --snaplen=snaplen] [ -z level | --compress-level=level] [ -Z method | --compress-type=method] inputuri [inputuri ...] outputuri DESCRIPTION
tracesplit splits the given input traces into multiple tracefiles -f bpf filter output only packets that match tcpdump style bpf filter -c count output count packets per output file. The output file will be named after the basename given in the outputuri with the packet num- ber of the first packet in this file. -b bytes output bytes bytes per file -i seconds start a new tracefile after "seconds" seconds -s unixtime don't output any packets before unixtime -e unixtime don't output any packets after unixtime -m maxfiles do not create more than "maxfiles" trace files -S snaplen Truncate packets to "snaplen" bytes long. The default is collect the entire packet. -z level Compress the data using the specified compression level, ranging from 0 to 9. Higher compression levels tend to result in better compression but require more processing power to compress. -Z compression-method Compress the data using the specified compression algorithm. Accepted methods are "gzip", "bzip2", "lzo" or "none". Default value is none unless a compression level is specified, in which case gzip will be used. EXAMPLES
create a 1MB erf trace of port 80 traffic. tracesplit -z 1 -Z gzip -f 'port 80' -b $[ 1024 * 1024 ] erf:/traces/bigtrace.gz erf:/traces/port80.gz LINKS
