Creating channels

• Creating channels from ptarmigan to each nodes
  • Following results are for feerate_per_kw = 10000.

../pay_fundin.py 800000 300000000
../ptarmcli -c [c-lightning NODE_ID] -f fund_yyyymmddhhddss.conf
../ptarmcli -l
(wait... status: "wait_minimum_depth")
rm fund_yyyymmddhhddss.conf

../pay_fundin.py 800000 400000000
../ptarmcli -c [eclair NODE_ID] -f fund_yyyymmddhhddss.conf
../ptarmcli -l
(wait... status: "wait_minimum_depth")
rm fund_yyyymmddhhddss.conf

../pay_fundin.py 800000 500000000
../ptarmcli -c [lnd NODE_ID] -f fund_yyyymmddhhddss.conf
../ptarmcli -l
(wait... status: "wait_minimum_depth")
rm fund_yyyymmddhhddss.conf

Waiting for opening channels

• Waiting 3 nodes change into "established" by observing with watch command every 10 seconds.

watch -n 10 "../ptarmcli -l | jq .result.peers[].status"
