Hello fellow CentOS users, on a freshly installed 7.2 machine and after reading https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/chap-Managing_Services_with_systemd.html I try to enable iptables with following commands: # cat /etc/centos-release CentOS Linux release 7.2.1511 (Core) # rpm -qa | grep iptables iptables-1.4.21-16.el7.x86_64 # sudo systemctl list-units --type service --all | grep iptables ? iptables.service...

I have CentOS 7 installed with GUI (Gnome 3.8.4) and I'm trying to follow the guide at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/s1-users-configui.html it speaks of "System > Administration" from the GUI or "system-config-users" from the command line, but I can't find either? I don't have a "System" top menu, only "Applications" and "Places", and when I try the c...

...1 which works as advertised. Now that shutdown is part of systemd <http://www.freedesktop.org/software/systemd/man/shutdown.html> and it is actually a link to it in CentOS 7, I've seen in the documentation <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/sect-Managing_Services_with_systemd-Power.html> that I can also use systemctl reboot But I can't find a way to provide a time specification in this latter form. What's the correct incantation? TIA, Carlos.

Me again, Another change to my Centos 7.2 system since my 'yum update' yesterday is that /var/log/dovecot is no longer written to. If I do 'systemctl status dovecot' I can see log entries. How can I now do the equiv or 'tail -f <logfile>' Also, why has this changed, and where is it documented?

Hi, if you use Samba on Red Hat Enterprise Linux you might find the following information useful: Since yesterday, the official Red Hat Enterprise Linux documentation contains a very detailed chapter about Samba: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/ch-file_and_print_servers#sect-Samba The documentation is up-to-date, based on frequent use cases, and contains a lot of procedures. Additionally, it provides very detailed information and examples on topics which often cause problems, such as ID mapping. Note that the documentation does not cove...

Hi, I have been using VNC on CentOS 7 server from last couple of months and it was running all fine till last night. Unfortunately, there was an abrupt power failure and system got restarted. Now, when I try to login with VNCviwer, it thrown an error message- "*Gnome - oh no! Something has gone wrong "* with a logout option. When I click on logout, I see black/dark gray screen with 3

I am setting up a CentOS 7 system as a file server within an AD domain, following the following Red Hat documentation: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/ch-file_and_print_servers Here is some information that likely complicates things: - we have a number of users and groups with sub-1000 uid or gid numbers which can't easily be addressed - the system is integrated into a OpenLDAP service but UNIX attributes are replicated to AD from OpenLDAP...
