After almost 3 months, I merged the ROHC-over-UDP tunnel and
ROHC-over-Ethernet tunnel applications [1].
I tested the 2 modes with a few ICMP messages, it seems to work as
expected. I would welcome your feedback on the app for your usage. You
can get the code on the main dev branch [2].
The way to call the program changed:
ROHC tunnel: make a ROHC-over-UDP or ROHC-over-Ethernet tunnel
usage:
rohctunnel [ version | help ]
rohctunnel TUNNEL [ ERROR ] [ DIR ]
Tunnel parameters:
TUNNEL := NAME TYPE PARAMS
NAME := STRING The name of the tunnel
TYPE := { udp | ethernet }
Tunnel parameters if TYPE = udp:
PARAMS := remote RADDR local LADDR port PORT
RADDR := IPV4_ADDRESS The IP address of the remote host
LADDR := IPV4_ADDRESS The IP address of the local host
PORT := PORT The UDP port to use (local and remote)
Tunnel parameters if TYPE = ethernet:
PARAMS := remote RADDR local ITF
RADDR := MAC_ADDRESS The Ethernet MAC address of the remote host
ITF := STRING The local interface to use, eg. eth0
[...]
Examples:
# rohctunnel rohc0 udp remote 192.168.0.20 local 192.168.0.21 port 5000
# rohctunnel rohc0 udp remote 192.168.0.20 local 192.168.0.21 port 5000 \
dir unidirectional
# rohctunnel rohc0 udp remote 192.168.0.20 local 192.168.0.21 port 5000 \
error uniform 1e-5 dir bidirectional
# rohctunnel rohc0 udp remote 192.168.0.20 local 192.168.0.21 port 5000 \
error burst 1e-5 2e-5
# rohctunnel rohc0 ethernet remote 01:02:03:04:05:06 local eth1
# rohctunnel rohc0 ethernet remote 01:02:03:04:05:06 local eth1 \
error burst 1e-5 2e-5
