Port cant open, missmatch ufw and nmap

Posted on September 17, 2018

Helo, Im trying to running cryptocurrency pool, but I face problem in firewall i think. I was open port using ufw its set allow, but when i cek from nmap, port stiil close. what i’m mising. Everything going well and run, so i think the main problem is firewall.

Blockchain full sync, everything running well and set in crontab (non password, so everything run): @reboot sudo bash yiimp_install_scrypt_ubuntu18.04/ screen-scrypt.sh @reboot sudo bash yiimp_install_scrypt_ubuntu18.04/ screen-stratum.sh @reboot sudo /var/web/main.sh @reboot sudo /var/web/loop2.sh @reboot sudo /var/web/blocks.sh @reboot ./elicoin/src/elicoind @reboot sudo /var/stratum/run.sh yescryptR16

elicoin.conf rpcuser=user rpcpassword=password rpcport=9994 rpcthreads=8 rpcallowip=127.0.0.1 onlynet=ipv4 maxconnections=12 daemon=1 gen=0 server=1

alertnotify=echo %s | mail -s “Elicoin alert!” hiddenmail@gmail.com blocknotify=blocknotify hiddendomain.com:6333 1425 %s

Firewall sudo ufw verbose 6333/tcp ALLOW Anywhere

Hey,

Have you checked if the pool service is listening on the port itself? You can open a port but you’ll need a service to listen on that port as well.

You can check the service is running and make sure it is configured on the correct port.
