on the same machine use --rpcaddr 127.0.0.1 to start the JSON RCP on the localhost network and only connections from your local machine reach the geth server
on a remote machine use --rpcaddr "0.0.0.0" to allow remote connections.
For both case in metamask indicate the machine ip (for the first case use http://127.0.0.1:8545 for the second case use the machine ip instead 127.0.0.1)
- its not connecting i have given --rpcaddr "0.0.0.0" if give the ip it shows error Fatal: Error starting protocol stack: listen tcp ip:8545: bind: cannot assign requested addressRanjeet– Ranjeet2019-08-07 10:21:17 +00:00Commented Aug 7, 2019 at 10:21
- Maybe another process is using that port try to use lsof -i :8545 to see if which process is listening2019-08-07 13:50:08 +00:00Commented Aug 7, 2019 at 13:50
