Admin RPC (port 10500)
IP Whitelisting
For a NodeCore instance, IP Whitelisting allows explicitly adding IPs such that only remote clients on that list can connect to your VeriBlock NodeCore instance.
1. In nodecore.properties, change the admin endpoint to bind to 0.0.0.0 and add a whitelist entry for your IP address.
Note that NodeCore expects IPv4, such as: http://whatismyip.host
#no longer directly bound to local host rpc.bind.address=0.0.0.0 #allow the specified IP to connect rpc.whitelist.addresses = 98.213.111.91
Note that the whitelist entry is a CSV list. It can be a:
- single IP address, e.g. 192.168.1.1
- "wildcard" IP, e.g. 192.168.*.* (which would be all IP's in the 192.168 range)
- CIDR representation, e.g. 192.168.0.0/16
2. If there is a firewall between the VeriBlock NodeCore instance and the device(s) you wish to allow access to, then open port 10500.
This will vary depending on your operating system. Here is an example for a RHEL-based linux distro (example is CentOS 7):
firewall-cmd --permanent --add-port=10500/tcp firewall-cmd --reload
3. Restart NodeCore.
Passwords
NOTE: Password protection is separate from whitelisting. Even if password is set up, the remote client must not be blocked via whitelisting.
#nodecore.properties rpc.whitelist.addresses=<my_client_ip>
To secure the RPC connection, you will either need to provide your own X509 certificate and private key, or use scripts/openssl-cert-gen.(sh|ps1) to generate the required certs and private keys. Once you have your certificates, you can configure the security mode and certificate paths
rpc.security.mode = ServerTls rpc.security.cert.chain.path = scripts/certs/server.crt rpc.security.private.key.path = scripts/certs/server.pem
The first time NodeCore runs, it will create a random RPC password and update the nodecore.properties file. To change this password, just modify your nodecore.properties file
rpc.security.password=rpcpass123
There will also be the following property added to your props file, which you will need to set to true to enforce the password authentication (disabled by default):
rpc.security.password.enabled=true
If you completely remove the password property, nodecore will generate a new random password when it starts.
To configure nodecore-cli to connect to your secured nodecore instance, see: HowTo_connect_NC_CLI_to_remote_NodeCore_instance
