| 15 | .SH DESCRIPTION |
|---|
| 16 | tracesplit splits one trace into multiple tracefiles |
|---|
| 17 | .TP |
|---|
| 18 | \fB\-f\fR bpf filter |
|---|
| 19 | output only packets that match tcpdump style bpf filter |
|---|
| 20 | |
|---|
| 21 | .TP |
|---|
| 22 | \fB\-c\fR count |
|---|
| 23 | output count packets per output file. The output file will be named after |
|---|
| 24 | the basename given in the outputuri with the packet number of the first packet |
|---|
| 25 | in this file. |
|---|
| 26 | |
|---|
| 27 | .TP |
|---|
| 28 | \fB\-b\fR bytes |
|---|
| 29 | output bytes bytes per file |
|---|
| 30 | |
|---|
| 31 | .TP |
|---|
| 32 | \fB\-i\fR seconds |
|---|
| 33 | start a new tracefile after "seconds" seconds |
|---|
| 34 | |
|---|
| 35 | .TP |
|---|
| 36 | \fB\-s\fR unixtime |
|---|
| 37 | don't output any packets before unixtime |
|---|
| 38 | |
|---|
| 39 | .TP |
|---|
| 40 | \fB\-e\fR unixtime |
|---|
| 41 | don't output any packets after unixtime |
|---|
| 42 | |
|---|
| 43 | .TP |
|---|
| 44 | \fB\-m\fR maxfiles |
|---|
| 45 | do not create more than "maxfiles" trace files |
|---|
| 46 | |
|---|
| 47 | .TP |
|---|
| 48 | \fB\-S\fR snaplen |
|---|
| 49 | Truncate packets to "snaplen" bytes long. The default is collect the entire |
|---|
| 50 | packet. |
|---|
| 51 | |
|---|
| 52 | .SH EXAMPLES |
|---|
| 53 | create a 1MB erf trace of port 80 traffic. |
|---|
| 54 | .nf |
|---|
| 55 | tracesplit erf:/traces/bigtrace.gz \-f 'port 80' \-b $[ 1024 * 1024 ] |
