#centos6.5

lokkit: Seems like a standard. AKA system-config-firewall-base in RH-land. Is used in a lot of puppet manifests floating around the foreman-associated projects and in SaltStack. Simple configuration, e.g.

lokkit --list-services

, add a hole for SSH

lokkit --service=ssh

or

lokkit --port=ssh:tcp

firewalld: in Fedora20 and CentOS7. This is a dynamic firewall configuration daemon (uses dbus) which can co-exist with lokkit.

The alternatives are? Shorewall? Just run iptables commands?

Debian got rid of it, claiming it was buggy and unmaintained.

Karena Centos terkenal dengan kesibukannya yang membuat mereka tidak sempat mengimpor, menguji, dan membuat ulang upgrade tool dari RHEL, mari kita upgrade Centos dengan tool Red Hat.

wget http://dev.centos.org/centos/6/upg/x86_64/Packages/preupgrade-assistant-1.0.2-33.el6.x86_64.rpm http://dev.centos.org/centos/6/upg/x86_64/Packages/preupgrade-assistant-contents-0.5.13-1.el6.noarch.rpm http://dev.centos.org/centos/6/upg/x86_64/Packages/preupgrade-assistant-ui-1.0.2-33.el6.x86_64.rpm http://dev.centos.org/centos/6/upg/x86_64/Packages/python-rhsm-1.9.7-1.el6.x86_64.rpm http://dev.centos.org/centos/6/upg/x86_64/Packages/redhat-upgrade-tool-0.7.22-1.el6.noarch.rpm sudo yum localinstall preupgrade-assistant-* sudo preupg sudo yum localinstall redhat-upgrade-tool-0.7.22-1.el6.noarch.rpm python-rhsm-1.9.7-1.el6.x86_64.rpm sudo rpm --import http://isoredirect.centos.org/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7 sudo redhat-upgrade-tool --network 7.0 --instrepo http://mirror.centos.org/centos/7.0.1406/os/x86_64/ --force sudo shutdown -r now
