[CentOS] CentOS 7 + MariaDB + phpMyAdmin

[Frank M. Ramaekers]

I can't seem to get phpMyAdmin working.  I got the ip address problem 
(permission) resolved, but now I'm getting a "Parallels H-Sphere" error "Error 
404: File Not found".  I've looked in all the logs and cannot determine what 
file is not found.

[CentOS] DHCPv6 prefix delegation

[Chris Adams]

Is there an DHCPv6 client in CentOS that supports prefix delegation
correctly?  The old version of dhclient can't set a requested prefix
delegation length, so isn't very useful, and I can't get the even-older
wide-dhcpv6 from EPEL to work.

[CentOS] CentOS 7 + Xfce + GDM : disable "switch user" ?

[Nicolas Kovacs]

Hi,

I have CentOS 7 + Xfce + GDM installed on all our local school's desktop
clients.

I'd like to disable the "switch user" menu entry, since our desktop
clients have a relatively limited amount of RAM. Most users tend to use
the "switch user" functionality to log off, and at the end of the day,
the computer has no RAM left.

I know there is a way to disable this functionality, I vaguely remember
having it done a few years ago on Slackware.

Any suggestions ?

Niki

Quite.

This is not an Ubuntu dig, but when I challenge some of the users about
the more dangerous sudo's they try, inevitably they say they got the
command from the net, and by that they usually mean Ubuntu forums.

Does CentOS changed the package management? :-)

I am wondering if there are some networking setting on the host I need

Resolved the issue by rebooting the computer but had to do that again later 
today. Does anyone have experience with docker under Centos 7?

Lots of people have experience, and it works well.  I believe the issue 
you are seeing, is that the Firewall rules are being modified and 
something is removing the rule that Docker adds to allow containers to 
use the host machines network interface.  When you reboot and restart 
the Docker daemon and the container, the network is correct again, but 
some tool (Firewalld) or something else is mucking around with the iptables.
