Source notes citing this source

• When built with EEP support, sngrep can send captured packets to a HOMER collector with -H (--eep-send) and listen for incoming HEP/EEP packets with -L (--eep-listen). in context
• sngrep cannot decrypt TLS sessions that use Perfect Forward Secrecy (DH or ECDH key exchange), even when the private key is supplied. in context
• sngrep captures RTP payload only when started with -r (--rtp). in context
• sngrep's TLS decryption supports only TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA and TLS_RSA_WITH_AES_256_GCM_SHA384, using a server private key given with -k (--keyfile), and needs the initial handshake in the capture. in context
• sngrep's interface consists of a Call List window, a Call Flow window (the ladder view), a Call Raw window and a Message Diff window. in context
• sngrep can send captured packets to a HEP/Homer collector (-H, --eep-send) and can listen for HEP-encapsulated packets (-L, --eep-listen). in context
• sngrep can write captured packets to a PCAP file using the -O (--output) option. in context
• The sngrep wiki states that its TLS decryption supports only a few RSA key-exchange cipher suites (TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_GCM_SHA384), needs the initial handshake, and cannot decrypt DH or ECDH sessions. in context
