### Building from sources
|
|
|
|
|
Prerequisites
|
|
|
|
|
|
|
|
|
|
- libncurses5 - for UI, windows, panels.
|
|
|
|
|
- libpcap - for capturing packets.
|
|
|
|
|
- libssl - (optional) for TLS transport decrypt using OpenSSL and libcrypt
|
|
|
|
|
- gnutls - (optional) for TLS transport decrypt using GnuTLS and libgcrypt
|
|
|
|
|
- libncursesw5 - (optional) for UI, windows, panels (wide-character support)
|
|
|
|
|
- libpcre - (optional) for Perl Compatible regular expressions
|
|
|
|
|
|
|
|
|
|
On most systems the commands to build will be the standard autotools procedure:
|
|
|
|
|

|
|
| configure flag | Feature |

## Usage

|
|
See `--help` for a list of available flags and their syntax
|
|
|
|
|
|

|
For example, sngrep can be used to view SIP packets from a pcap file, also applying filters
|
|
|
|
|
|
|
|
|
|
sngrep -I file.pcap host 192.168.1.1 and port 5060
|
|
|
|
|
|
|
|
|
|
or live capturing, saving packets to a new file
|
|
|
|
|
|
|
|
|
|
sngrep -d eth0 -O save.pcap port 5060 and udp
|
|
