Cloud and php
by Robert Moskowitz 08 Aug '17

08 Aug '17

I am looking at cloud software. On Centos7-armv7hl, of course. I was pointed to Nextcloud, but v11 CAN work with php 5.4 in Centos7, but recommends at least 5.5 for security updates and performance (important on arm), but recommends php 7. Nextcloud 12 has a minimum requirement of php 5.6 (according to their install pages). So. What are others doing for: Cloud Php ??? I could always start with Fedora26, but want to stay with Centos if I can. thank you.

Light-weight window manager, recommendations
by m.roth＠5-cent.us 08 Aug '17

08 Aug '17

So, I've mentioned that I've got an original netbook, circa 2009, and I'm going to put CentOS on it. 32 bit. Not huge disk, old Atom processor, not tons of memory. Any recommendations for a light-weight window manager? Before I went to KDE, I used fvwm2, and all I'm going to do is use it to read webmail and browse, read news, etc, so I don't need a lot. mark

centos7: looking for libwebpdemux
by wwp 07 Aug '17

07 Aug '17

Hello there, I'm looking for libwebpdemux.so, possibly 0.4.x. I had it installed on my CentOS6, from EPEL, but now on CentOS7, EPEL doesn't provide it at all. Anybody knows about it? Maybe a rpm rebuild would do it? Regards, -- wwp

VDQ Repos for CentOS 7
by Beartooth 06 Aug '17

06 Aug '17

I have a woefully dumb question. When I tell my wife's laptop, with CentOS 7 installed and a live ethernet cable plugged into it, "yum update," it fails saying that it doesn't see any repos. What do I need to do to?

What RH-like on a Dell XPS 15 (9590)?
by wwp 05 Aug '17

05 Aug '17

Hello there, I've just got a Dell XPS 15 (9590) at work and need to set up a stable GNU/Linux system on it. I thought of CentOS7, but.. obviously its kernel can't run on this hardware. What would you recommend? Waiting for CentOS8 is not an option unless it's a question of few weeks. Are there respins of the CentOS7 DVDs w/ more top-recent kernels? I'm know of Fedora 26 or course, and not willing to switch to Ubuntu 16.10 at all. Regards, -- wwp

Some remnants rebase did not take care of? regards, L.

Hello All, I 've gotten myself into trouble by running out of disk space. On an all-in-one Ovirt system some users have filled up a Windows7 virtual machine and in doing so filled up an nfs mount and in doing so filled up a root partition: B estandssysteem Grootte Gebruikt Besch Geb% Aangekoppeld op /dev/mapper/centos-root 50G 46G 4,8G 91% / devtmpfs 7,9G 0 7,9G 0% /dev tmpfs 7,9G 0 7,9G 0% /dev/shm tmpfs 7,9G 8,5M 7,9G 1% /run tmpfs 7,9G 0 7,9G 0% /sys/fs/cgroup /dev/md127 498M 106M 393M 22% /boot /dev/mapper/centos-home 20G 33M 20G 1% /home /dev/mapper/centos-var 360G 623M 360G 1% /var hotelcaw:/mnt/iso 50G 46G 4,8G 91% /rhev/data-center/mnt/hotelcaw:_mnt_iso tmpfs 1,6G 0 1,6G 0% /run/user/0 I tried to remedy that today by using ssm to add storage.

CentOS SDR Support
by Chris Olson 02 Aug '17

02 Aug '17

Several weeks ago, we posted a message seeking information about time sources. There were many helpful and educational responses. An excerpt from one of the responses is included below. We have been following up with regard to how SDR capabilities might be used for obtaining time using SDR dongles as well as using the time source product referenced in that response. Our SDR investigation has yielded many sources of information, but not a source dedicated to CentOS support for SDR products. Is there a CentOS subgroup and mail list directly involved with SDR device or system support? The SDR information resulting from our search has many references to ADS-B and the P3. It is almost like one absolutely must have a P3 to make use of SDR products. One thing that we did not find was any reference at all to SDR products and software for monitoring the frequencies used by recreational Remote Controlled Aircraft. Thanks again for all the helpful system time responses.
