17 | .SH DESCRIPTION |
---|
18 | tracesplit splits the given input traces 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 |
---|
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. |
---|
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 | |
---|
45 | .TP |
---|
46 | \fB\-m\fR maxfiles |
---|
47 | do not create more than "maxfiles" trace files |
---|
48 | |
---|
49 | .TP |
---|
50 | \fB\-S\fR snaplen |
---|
51 | Truncate packets to "snaplen" bytes long. The default is collect the entire |
---|
52 | packet. |
---|
53 | |
---|
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 | |
---|
66 | .SH EXAMPLES |
---|
67 | create a 1MB erf trace of port 80 traffic. |
---|
68 | .nf |
---|
69 | tracesplit \-z 1 -Z gzip \-f 'port 80' \-b $[ 1024 * 1024 ] |
