ohrwurm - RTP模糊器

:~# ohrwurm
ohrwurm-0.1

usage: ohrwurm -a <IP target a> -b <IP target b> [-s <randomseed>] [-e <bit error ratio in %>] [-i <interface>] [-A <RTP port a> -B <RTP port b>]

    -a <IPv4 address A in dot-decimal notation> SIP phone A
    -b <IPv4 address B in dot-decimal notation> SIP phone B
    -s <integer> randomseed (default: read from /dev/urandom)
    -e <double> bit error ratio in % (default: 1.230000)
    -i <interfacename> network interface (default: eth0)
    -t suppress RTCP packets (default: dont suppress)
    -A <port number> of RTP port on IP a (requires -B)
    -B <port number> of RTP port on IP b (requires -A)
       note: using -A and -B skips SIP sniffing, any RTP can be fuzzed
