| [1369834] | 17 | .SH DESCRIPTION |
|---|
| [5d022cd] | 18 | tracesplit splits one trace into multiple tracefiles |
|---|
| 19 | .TP |
|---|
| 20 | \fB\-f\fR bpf filter |
|---|
| 21 | output only packets that match tcpdump style bpf filter |
|---|
| 22 | |
|---|
| 23 | .TP |
|---|
| 24 | \fB\-c\fR count |
|---|
| [e86124e] | 25 | output count packets per output file. The output file will be named after |
|---|
| 26 | the basename given in the outputuri with the packet number of the first packet |
|---|
| 27 | in this file. |
|---|
| [5d022cd] | 28 | |
|---|
| 29 | .TP |
|---|
| 30 | \fB\-b\fR bytes |
|---|
| 31 | output bytes bytes per file |
|---|
| 32 | |
|---|
| 33 | .TP |
|---|
| 34 | \fB\-i\fR seconds |
|---|
| 35 | start a new tracefile after "seconds" seconds |
|---|
| 36 | |
|---|
| 37 | .TP |
|---|
| 38 | \fB\-s\fR unixtime |
|---|
| 39 | don't output any packets before unixtime |
|---|
| 40 | |
|---|
| 41 | .TP |
|---|
| 42 | \fB\-e\fR unixtime |
|---|
| 43 | don't output any packets after unixtime |
|---|
| 44 | |
|---|
| [634089d] | 45 | .TP |
|---|
| 46 | \fB\-m\fR maxfiles |
|---|
| 47 | do not create more than "maxfiles" trace files |
|---|
| 48 | |
|---|
| [0a65ed8] | 49 | .TP |
|---|
| 50 | \fB\-S\fR snaplen |
|---|
| [0bfd4a0] | 51 | Truncate packets to "snaplen" bytes long. The default is collect the entire |
|---|
| 52 | packet. |
|---|
| [0a65ed8] | 53 | |
|---|
| [bfe8535] | 54 | .TP |
|---|
| 55 | \fB\-z\fR level |
|---|
| 56 | Compress the data using the specified compression level, ranging from 0 to 9. |
|---|
| 57 | Higher compression levels tend to result in better compression but require |
|---|
| 58 | more processing power to compress. |
|---|
| 59 | |
|---|
| 60 | .TP |
|---|
| 61 | \fB-Z\fR compression-method |
|---|
| 62 | Compress the data using the specified compression algorithm. Accepted methods |
|---|
| 63 | are "gzip", "bzip2", "lzo" or "none". Default value is none unless a |
|---|
| 64 | compression level is specified, in which case gzip will be used. |
|---|
| 65 | |
|---|
| [5d022cd] | 66 | .SH EXAMPLES |
|---|
| 67 | create a 1MB erf trace of port 80 traffic. |
|---|
| 68 | .nf |
|---|
| [bfe8535] | 69 | tracesplit \-z 1 -Z gzip \-f 'port 80' \-b $[ 1024 * 1024 ] |
