I've been trying to set up a full Solana RPC node, but kept having this issue.
[INFO solana_net_utils]Checking that tcp ports [{8000, TcpListener { addr: 0.0.0.0:8000, fd: 85})] are reachable from 139.178.94.143:8001
[ERROR solana_net_utils] Received no response at tcp/8000, check your port configuration: timed out waiting on receive operation
I'm using this statement to bring up the RPC node
exec agave-validator \
--identity /home/sol/validator-keypair.json \
--known-validator 5D1fNXzvv5NjV1ysLjirC4WY92RNsVH18vjmcszZd8on \

Have allowed the firewall using the following command
sudo ufw status
sudo ufw allow 8000:8020/udp
sudo ufw allow 8000:8899/udp
Does anyone has a solution for this? Thanks!

Are you running the node behind a firewall/natted that is blocking the port upstream? Useful tool is nmap that lets you port can your machine

You only opened UDP. The error says
tcp/8000
and all your ufw rules are
/udp
.
sudo ufw allow 8000:8020/tcp
sudo ufw allow 8899/tcp
Dynamic port range needs both. Gossip/TPU is UDP, but repair and a couple others are TCP, which is what that startup check is hitting.
If it still fails, check:
Cloud provider? ufw isn't enough, open the same ports in the security group too.
Behind NAT? Either forward the ports or pass
--public-rpc-address
.
From another box:
nc -vz <your-ip> 8000
If that times out it's still firewall/NAT, not the validator.
