The RHEL 7.2 release doesn’t only bring an important Systemd update (v219). It also contains several goodies, some still to discover.
Among these, two come to my mind.
Firstly, several Firewalld configuration files have been added making administrator’s life easier:
- iscsi-target allows TCP-UDP/3260,
- rsyncd allows TCP-UDP/873,
- freeipa-ldap allows TCP/80, TCP/443, TCP-UDP/88, TCP-UDP/464, UDP/123, TCP/389,
- freeipa-ldaps allows TCP/80, TCP/443, TCP-UDP/88, TCP-UDP/464, UDP/123, TCP/636,
- freeipa-replication allows TCP/7389.
As an exercise for RHCE candidates, you can guess which protocols are specified in the freeipa-ldap* lists.
Secondly, a nice shortcut has been introduced. Instead of typing:
# systemctl enable httpd ntpd # systemctl start httpd ntpd
You can now type:
# systemctl enable --now httpd ntpd
This also works with the –disable and –mask options.
Remember, this is only coming with the RHEL 7.2 release. As the exams still don’t use this version (they use RHEL 7.0 or RHEL 7.1), you can’t use these goodies now.
