# sngrep [![Build Status](https://travis-ci.org/irontec/sngrep.svg)](https://travis-ci.org/irontec/sngrep)



sngrep is a tool for displaying SIP calls message flows from terminal.



It supports live capture to display realtime SIP packets and can also be used

as PCAP viewer.

## Installing



### Binaries

* [Debian / Ubuntu](https://github.com/irontec/sngrep/wiki/Installing-Binaries#debian--ubuntu)

* [CentOS / RedHat / Fedora](https://github.com/irontec/sngrep/wiki/Installing-Binaries#centos--fedora--rhel)

* [Alpine Linux](https://github.com/irontec/sngrep/wiki/Installing-Binaries#alpine-linux)

* [Gentoo](https://github.com/irontec/sngrep/wiki/Installing-Binaries#gentoo)

* [Arch](https://github.com/irontec/sngrep/wiki/Installing-Binaries#arch)

* [OSX](https://github.com/irontec/sngrep/wiki/Installing-Binaries#osx)

* [OpenWRT/LEDE](https://github.com/irontec/sngrep/wiki/Installing-Binaries#openwrtlede)



### 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

 - zlib - (optional) for gzip compressed pcap files



On most systems the commands to build will be the standard autotools procedure:



    ./bootstrap.sh

	./configure

	make

	make install (as root)



You can pass following flags to ./configure to enable some features



| configure flag | Feature |

| ------------- | ------------- |

| `--with-openssl` | Adds OpenSSL support to parse TLS captured messages (req. libssl)  |

| `--with-gnutls` | Adds GnuTLS support to parse TLS captured messages (req. gnutls)  |

| `--with-pcre`|  Adds Perl Compatible regular expressions support in regexp fields |

| `--with-zlib`|  Enable zlib to support gzip compressed pcap files |

| `--enable-unicode`   | Adds Ncurses UTF-8/Unicode support (req. libncursesw5) |

| `--enable-ipv6`   | Enable IPv6 packet capture support. |

| `--enable-eep`   | Enable EEP packet send/receive support. |



Instead of using autotools, sngrep could be build with CMake, e.g.:



    mkdir build && cd build

    cmake [] ..

    make

    make install (as root)



You can pass following options to cmake to enable some features



| CMake option | Feature |

| ------------- | ------------- |

| `-D WITH_OPENSSL=ON` | Adds OpenSSL support to parse TLS captured messages (req. libssl)  |

| `-D WITH_GNUTLS=ON` | Adds GnuTLS support to parse TLS captured messages (req. gnutls)  |

| `-D WITH_PCRE=ON`|  Adds Perl Compatible regular expressions support in regexp fields |

| `-D WITH_ZLIB=ON`|  Enable zlib to support gzip compressed pcap files |

| `-D WITH_UNICODE=ON` | Adds Ncurses UTF-8/Unicode support (req. libncursesw5) |

| `-D USE_IPV6=ON` | Enable IPv6 packet capture support |

| `-D USE_EEP=ON` | Enable EEP packet send/receive support |

| `-D CPACK_GENERATOR=DEB` | `make package` builds a Debian package |

| `-D CPACK_GENERATOR=RPM` | `make package` builds a RPM package |



You can find [detailed instructions for some distributions](https://github.com/irontec/sngrep/wiki/Building) on wiki.



## 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



## Configuration



You can configure some options using [sngreprc](https://github.com/irontec/sngrep/wiki/Configuration) file
