A short HOWTO would be as follows:
The following instructions have been tested with (K)Ubuntu 16.04
There is another short howto to set up an appropriate Ubuntu 16.04 VirtualBox image below
- Get MLC:
git clone https://github.com/axn/mlc.git mlc.git
cd mlc.git
- Become root:
sudo su
- Source MLC to your bash environment
cd /home/mlc/mlc.git # assuming mlc was installed here.
. ./mlc-vars.sh
- Setup your local host & prepare a simple debian container system:
less mlc-setup-host.sh # check what is done here...
./mlc-setup-host.sh
- This takes a while...
- Usually choose yes.
- For Dumpcap support for non-super users choose: yes
(Once this completed only
./mlc-init-host.sh
would be needed after any system reboot)
- Create 30 containers called mlc1000... mlc1029:
mlc_loop -i 1000 -a 1029 -c
- Boot them:
mlc_loop -i 1000 -a 1029 -b
- Create a 10x3 grid network among them using bridge mbr1 (eth1 inside containers)
mlc_configure_grid 1
- Execute bmx7 in all containers
mlc_loop -i 1000 -a 1029 -e "bmx7 -f0 dev=eth1.11"
- Attach to container mlc1000 and get bmx7 debug info to monitor the network converging...
lxc-attach -n mlc1000 -- bmx7 -lc parameters show=status show=interfaces show=links show=originators
# or retrieve just individual perspectives in non-loop mode:
lxc-attach -n mlc1000 -- bmx7 -c parameters show=tunnels
On my 3Ghz Intel Dual core notebook it takes about 2 minutes to converge even 100 nodes at high CPU load, then stabilizes around 40% CPU load.
- Copy and paste Crypto IPv6 from mlc1019 (seen via previous command) one can verify that pinging from top left node mlc1000 to top right node mlc1009 takes 9 hops:
lxc-attach -n mlc1000 -- traceroute6 fd70:1191:c909:1e4e:4c9c:4d4a:33eb:b09b
traceroute to fd70:1191:c909:1e4e:4c9c:4d4a:33eb:b09b (fd70:1191:c909:1e4e:4c9c:4d4a:33eb:b09b), 30 hops max, 80 byte packets
1 fd70:166:2d16:1ff6:253f:d0bc:1558:d89a (fd70:166:2d16:1ff6:253f:d0bc:1558:d89a) 0.110 ms 0.048 ms 0.046 ms
2 fd70:aad9:c0f5:8c20:a082:a462:a859:210d (fd70:aad9:c0f5:8c20:a082:a462:a859:210d) 0.068 ms 0.051 ms 0.051 ms
...
9 fd70:1191:c909:1e4e:4c9c:4d4a:33eb:b09b (fd70:1191:c909:1e4e:4c9c:4d4a:33eb:b09b) 0.084 ms 0.067 ms 0.060 ms
- Start also olsrd2 and babeld in nodes:
mlc_loop -a 1029 -e "olsrd2_static --set=global.fork=1 --set=interface.multicast_v4=- eth1.12"
mlc_loop -a 1029 -e "olsrd2_static --set=global.fork=1 --load /etc/olsrd2.conf"
mlc_loop -a 1029 -e "babeld -D -w -c /etc/babeld.conf eth1.13"
- Do some more advanced experiments:
# Apply some wireshark statistics filter to observe protocol overhead:
# filter on 1011_1
# BMX7 filter: (eth.src == a0:cd:ef:10:00:01) && (udp.srcport == 6270)
# olsr2 filter: (eth.src == a0:cd:ef:10:00:01) && (udp.srcport == 269)
# babel filter: (eth.src == a0:cd:ef:10:00:01) && (udp.srcport == 6696)
# Add unicast hnas to bmx7 descriptions
for i in $(seq 1000 1069); do mlc_loop -i $i -e "bmx7 -c u=$(mlc_loop -i $i -e "ip a show dev eth1.11" | grep fd01 | cut -d' ' -f6 | cut -d '/' -f1)/128"; done
# Monitor path between two e2e nodes:
root@mlc1000:~#
watch -n1 timeout 0.3 traceroute6 -n fd01::a0cd:ef10:2901:0:1 # bmx7
watch -n1 timeout 0.3 traceroute6 -n fd02::a0cd:ef10:2901:0:1 # olsr2
watch -n1 timeout 0.3 traceroute6 -n fd03::a0cd:ef10:2901:0:1 # bmx7
# Set links on and off:
root@mlc:
mlc_link_set 1 1050 1 1059 3 3
mlc_link_set 1 1050 1 1059 0 0
# Tune Bmx7 link-discovery:
mlc_loop -a 1079 -e "bmx7 -c linkWindow=5 linkTimeout=10000"
# Start some topology dynamics:
while true; do for X in $(seq 20 59); do (mlc_link_set 1 10$X 1 10$((($X + 10))) 0 0; sleep 30; mlc_link_set 1 10$X 1 10$((($X + 10))) 3 3)& sleep 4; done; done
# Enable some malicious behavior. Drop packets towards mlc1029:
root@mlc1059:~#
ip6tables -I FORWARD -o eth1.11 -d fd01::a0cd:ef10:2901:0:1 -j DROP
ip6tables -I FORWARD -o eth1.12 -d fd02::a0cd:ef10:2901:0:1 -j DROP
ip6tables -I FORWARD -o eth1.13 -d fd03::a0cd:ef10:2901:0:1 -j DROP
ip6tables -L -nv
ip6tables -F
# Let Bmx7 distrust a known malicious node:
# On mlc1029 (and mlc1000):
for k in $(bmx7 -c show=keys | cut -d' ' -f2); do bmx7 -c setTrustedNode=$k; done
bmx7 -c trustedNodesDir=/etc/bmx7/trustedNodes/
bmx7 -c setTrustedNode=-$(bmx7 -c show=keys | grep mlc1059 | cut -d' ' -f2)
