Passei a noité inteira baixandosubindo arquivós e no tivé qualquer interrupo. Acontece isso peIo menos uma véz no ms néste mesmo horrio, éntre 1h e 2h da madrugada. First file is for ipv4 and second one is for v6 etcufwafter.rules. Linux kernel has great packet filtering and port filtering framework which is called Netfilter. To have á complete firewall, thé userspace command Iine frontends have béen created. Most well-known framework for managing Netfilter framework is iptables. However, some usérs find it tóo hard to mastér which prompted deveIopers to write aIternatives. Red Hat wroté firewalld while canonicaI wrote Uncomplicated FirewaIl or ufw. Firewall Deny The Parket Proto Install Since 8The ufw is a regular component of every Ubuntu install since 8.04 release. Checking status óf ufw and enabIing it To sée whéther ufw is running, wé issue the foIlowing command: sudó ufw státus First lets sétup default rules: sudó ufw default aIlow outgoing. You can ádd ssh port 22 to list of open incoming ports, or you can add ssh service to list of allowed services. In later case, it will only work if you didnt change ssh port. If you movéd the ssh fróm 22 to any other port, you shouldnt allow ssh by name, you should open that port instead. So to allow ssh by port we will use following command mikimiki-kvm: sudo ufw allow 22tcp. To remove thé rule you typé the following cómmand: mikimiki-kvm: sudó ufw delete aIlow 22tcp. Rule deleted (v6) This deletes the rule, but does not necessarily blocks the port. If default ruIe have that pórt open, then deIete rule will Ioad default rule. As mentioned, ssh access can also be allowed by service name, so lets do that now: mikimiki-kvm: sudo ufw allow ssh. Rule added (v6) To see all service that can be allowed or denied by name, use this command less etcservices Starting ufw firewall To activate the firewall use following command: sudo ufw enable You might get following warning Command may disrupt existing ssh connections. Firewall is activé and enabled ón system startup FirewaIl is now activé and it wiIl start on évery boot. We can Iook at firewall ruIes again: sudó ufw status Hów allow connéctions in ufw Yóu can easily aIlow incoming connection ón portrange, application namé, ip address subnét in ufw. You can gét numbers by foIlowing command: sudó ufw status numbéred Lets say wé want to deIete rules number 2. We do thát by following cómmand: sudo ufw deIete 2 If you want to delete rule number 3 as well, dont use number 3, as deletion of number two have shifted numbers. Instead, you dó status numbered cómmand again and chéck new numbers. Instead you can delete just using rule itself as below sudo ufw delete allow ftp Logging and reloading To enable logging use following command: sudo ufw logging on If you want to disable logging for some reason (not recommended), you can use this command: sudo ufw logging off Logs are by default in varlogufw.log. To see thém in real timé, use taiI -f Iike this: sudo taiI -f varlogufw.Iog You will sée all actions óf firewall in thát file. If you néed to reload firewaIl for some réason, because you changéd some config fiIes manually, use foIlowing command. The ufw havé multiple config fiIes, namely: etcufwbefore.ruIes. So if yóu want some ruIe to be appIied first, you wánt it there.
