Send authenticate request with simulator

authenticate: CHAP

enter into authenticate container: docker-compose exec auth bash

run simulator in container:

radclient -D /app/tools/simulator/etc/dictionary -d /app/etc/dictionary 127.0.0.1:1812  auth  'testing123'  < /app/tools/simulator/radius_test/auth/chap.conf

authenticate: PAP

enter into authenticate container: docker-compose exec auth bash

run simulator in container:

radclient -D /app/tools/simulator/etc/dictionary -d /app/etc/dictionary 127.0.0.1:1812  auth  'testing123'  < /app/tools/simulator/radius_test/auth/pap.conf

authenticate: MSCHAPv2

1. docker-compose up -d auth_test, listen on port 2812

2. Access Controller route traffic to 2812

authenticate: EAP-GTC

add USE_GTC=1 in .env and restart docker container

enter into authenticate container: docker-compose exec auth bash

run simulator in container:

./eapol_test -c /app/tools/simulator/eap_test/eapol_test.conf.peapv1.gtc -a 127.0.0.1 -p 1812 -s testing123 -r 0 -N 30:s:FF-FF-FF-FF-FF-FF -N 32:s:AC

authenticate: EAP-MSCHAPv2

remove USE_GTC=0 in .env and restart docker container

enter into authenticate container: docker-compose exec auth bash

run simulator in container:

./eapol_test -c /app/tools/simulator/eap_test/eapol_test.conf.peapv1.mschapv2 -a 127.0.0.1 -p 1812 -s testing123 -r 0 -N 30:s:FF-FF-FF-FF-FF-FF -N 32:s:AC

Send authenticate request with simulator

enter into accounting container: docker-compose exec acct bash

run simulator in container:

./radclient -D /app/tools/simulator/etc/dictionary -d /app/etc/dictionary 127.0.0.1:1813  acct  'testing123'  < /app/tools/simulator/radius_test/acct/i.conf

./radclient -D /app/tools/simulator/etc/dictionary -d /app/etc/dictionary 127.0.0.1:1813  acct  'testing123'  < /app/tools/simulator/radius_test/acct/u.conf

./radclient -D /app/tools/simulator/etc/dictionary -d /app/etc/dictionary 127.0.0.1:1813  acct  'testing123'  < /app/tools/simulator/radius_test/acct/t.conf

Send Dynamic Authorization Extensions request with simulator

disconnect

enter into accounting container: docker-compose exec dae bash

run simulator in container:

./radclient -D /app/tools/simulator/etc/dictionary -d /app/etc/dictionary 127.0.0.1:3799  disconnect  'testing123'  < /app/tools/simulator/radius_test/dae/disconnect.conf
