C7 arm graphical desktops
by Robert Moskowitz 31 Aug '15

31 Aug '15

What desktops will be available? I vote for Xfce. I was interduced to it with Fedora-arm and I using it also on my Fedora x86_64 notebook. Low memory, low cpu, low battery consumption. Normally I will NOT have a gui on a server, but there are times...

Please add ntpd to minimum build
by Robert Moskowitz 31 Aug '15

31 Aug '15

Probably be doing this anyway? but.. The first thing I have to do on a new image (other than set root password) is to get ntpd running to get the current date/time as no battery rtc. It is bad enough that all the boot messages have the wrong time, but at least to get the time as soon as possible. BTW, I suggested some time ago on the Fedora-arm list a service that regularly (perhaps every 5 min) writes the current date/time to a file. At boot time, a script reads this and sets the date/time so that the boot messages (and if network has problems) is closer to the actual time rather than reporting it is 1970.

It kinda works. Has HDMI, but ethernet card doesn't work. Is kernel compiled it same config as RedHat's one (e.g. without many drivers for older cards)? -- Over And Out MoonWolf

nf_conntrack: automatic helper assignment is deprecated
by Robert Moskowitz 31 Aug '15

31 Aug '15

On booting te Centos pre-alpha on my Cubietruck I always see: [ 42.855609] nf_conntrack: automatic helper assignment is deprecated and it will be removed soon. Use the iptables CT target to attach helpers instead. I see both firewalld and iptables installed on the original image.

Cubieboard2 eth0 link bounced?

[ 3290.069352] stmmaceth 1c50000.ethernet eth0: Link is Down [ 3292.074401] stmmaceth 1c50000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx Why? I am plugged into an HP2524 switch. Quite a good switch; not some $5 special.

Cubieboard2 - selinux testing
by Robert Moskowitz 31 Aug '15

31 Aug '15

So I set selinux to 'permissive' and rebooted. Took some time and a few interesting messages occured on the serial console like: [ 132.847434] systemd-readahead[302]: open(/etc/selinux/targeted/modules/active/policy.kern) failed: Too many levels of symbolic links Finally get the login prompt and log in on the serial console as root. I then move sshd to a different port. I have been doing this for years and know the selinux secret codes. First I need to: yum install policycoreutils-python Then: semanage port -a -t ssh_port_t -p tcp 745 firewall-cmd --permanent --add-port=745/tcp firewall-cmd --reload vi /etc/ssh/sshd_config <- change port to 745, and that is not the real port number I use. systemctl restart sshd.service After the semanage command I got: [ 310.545666] SELinux: Permission audit_read in class capability2 not defined in policy. [ 310.554040] SELinux: Class binder not defined in policy. [ 310.559671] SELinux: the above unknown classes and permissions will be allowed But I am able to ssh into my server. So are these messages an indicator that things are not right? I of course want to move on the selinux 'targeted' to get this secure. I plan on putting bind on this unit and have it for my testing dns server. Advise?

Cubieboard2 sata boot
by Robert Moskowitz 31 Aug '15

31 Aug '15

I am booted off sata by doing the following: I took David's image: http://www.mininodes.com/uploads/cubieboard2-centos-image.img.tar.gz And first dd it to a 4Gb mSD card. I used gparted to delete all three partitions. This way I was assured to get the uboot David used. Then I dd it to a 80Gb sata drive. I use gparted to increase the size of the / partition. I put the uboot only mSD card in the slot and attached to sata drive and it booted right up. Here is what the serial console showed.

My test platforms
by Robert Moskowitz 28 Aug '15

28 Aug '15

I only have one Cubietruck available for testing purposes. I have 2 - 4 Cubieboard2 units. To date, all of my work has been on this one Cubietruck. If I had an image for the Cubieboard2, I would put those into play. For example, I need a DNS server for my Samba development. I have that running on a F22 C2 right now. If I had a C2 image to work with, I would spin that up to replace F22. I did see that there was a successful test on the C2, but nowhere to get the image. Though if I DO spin up more platforms, I am going to have to get another Anker multi-port power supply: http://www.amazon.com/Anker-PowerPort-Charging-Multi-Port-Charger/dp/B00VH8… I see they have come down $6 since I bought one last October. These work great in powering 5 Cubieboards each. But DON'T plug in a phone as well, or the smart logic will reduce the Amps to the Cubieboards to 1A which is bad.

phpmyadmin
by Robert Moskowitz 28 Aug '15

28 Aug '15

I have installed mariadb to develop the dns backend. Still researching what tables are needed, but... I would like to have phpmyadmin, but that is part of epel. Could we at least start with the noarch rpms from epel7 (there IS an epel7?) and grow from there? I suppose I can bring in the epel7 repo and carefully install only noarch rpms...

Pro tip: You can probably get away with using any missing packages from F19 armv7hl, F19 and EL7 are very, very similar. F17 armv5tel packages on RSEL7 are also likely to work. Just bear in mind that those packages will be unmaintained as those distros are EOL so you will be on your own for any security patches for them. Gordan
