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.
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. |
You can find detailed instructions for some distributions on wiki.
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
You can configure some options using sngreprc file
