# API Reference: Wireshark and tshark
|
|
|
|
## Live Capture
|
|
```bash
|
|
tshark -i eth0 # Capture on interface
|
|
tshark -i eth0 -w output.pcap # Write to file
|
|
tshark -i eth0 -a duration:60 # Capture for 60 seconds
|
|
tshark -i eth0 -f "port 80" # BPF capture filter
|
|
tshark -D # List interfaces
|
|
```
|
|
|
|
## Display Filters (Read Mode)
|
|
```bash
|
|
tshark -r capture.pcap -Y "<filter>"
|
|
```
|
|
|
|
### Common Filters
|
|
| Filter | Purpose |
|
|
|--------|---------|
|
|
| `ip.addr == 10.0.0.5` | Traffic to/from IP |
|
|
| `tcp.port == 443` | Traffic on port 443 |
|
|
| `http.request` | HTTP requests only |
|
|
| `dns.qr == 0` | DNS queries only |
|
|
| `tls.handshake.type == 1` | TLS Client Hello |
|
|
| `tcp.flags.syn == 1 && tcp.flags.ack == 0` | SYN-only |
|
|
| `frame.len > 1500` | Large frames |
|
|
| `tcp.analysis.retransmission` | Retransmissions |
|
|
| `icmp` | ICMP traffic |
|
|
|
|
## Field Extraction
|
|
```bash
|
|
tshark -r capture.pcap -T fields \
|
|
-e frame.time -e ip.src -e ip.dst -e tcp.dstport \
|
|
-E separator="," -E header=y
|
|
```
|
|
|
|
### Common Fields
|
|
| Field | Description |
|
|
|-------|-------------|
|
|
| `frame.time` | Packet timestamp |
|
|
| `ip.src` / `ip.dst` | Source/destination IP |
|
|
| `tcp.srcport` / `tcp.dstport` | TCP ports |
|
|
| `http.request.method` | HTTP method |
|
|
| `http.host` | HTTP Host header |
|
|
| `http.request.uri` | Request URI |
|
|
| `http.user_agent` | User-Agent |
|
|
| `dns.qry.name` | DNS query name |
|
|
| `tls.handshake.extensions_server_name` | TLS SNI |
|
|
| `tls.handshake.ja3` | JA3 fingerprint |
|
|
|
|
## Statistics

|
```bash
|
|
tshark -r capture.pcap -q -z conv,ip # IP conversations

```bash
|
|
tshark -r capture.pcap --export-objects "http,/output/dir"
|
|
tshark -r capture.pcap --export-objects "smb,/output/dir"
|
|
tshark -r capture.pcap --export-objects "tftp,/output/dir"
|
|
tshark -r capture.pcap --export-objects "imf,/output/dir"
|
|
```
|
|
|
|
## Stream Following
|
|
```bash
|
|
tshark -r capture.pcap -z follow,tcp,ascii,0
|
|
tshark -r capture.pcap -z follow,http,ascii,0
|
|
tshark -r capture.pcap -z follow,tls,ascii,0
