C7, kernel oops, sllub.c
by m.roth＠5-cent.us 11 Jun '18

11 Jun '18

Anyone else seeing this: I've seen it with different line # as an upstream bug: kernel BUG at mm/slub.c:3601. When I look for slub.c, I think I found a slightly different version, since that's a blank line, but it's in the function slab_memory_callbac. On a possibly related note, one of my users who runs debian has been getting a ton of radeon errors... and guess what, it's to do with slab_callback. Anyone want me to post the backtrace from the abort? mark

Problem with bugs.centos.org
by Nicolas Kovacs 11 Jun '18

11 Jun '18

Hi, I wanted to create an account on bugs.centos.org to report a minor but annoying bug with Dolphin. After trying to register by providing the login (kikinovak) and email address (info(a)microlinux.fr) I'm told that the email is already in use. Uh oh. Maybe I already created an account years ago and then forgot about it. So I click on the field for forgotten passwords, only to be told that there is no one under that name or email address. So I'm hitting a wall. Maybe one of the admins of bugs.centos.org is reading this and can help me out?

Centos 7 and priorities
by Michael Hennebry 11 Jun '18

11 Jun '18

I've recently changed to Centos 7. My recollection from C6 is that a couple useful repositories need yum priorities to prevent some mixups. I do not remember what they are. My C6 is gone. Google has not told me what C6 repositories were. In the near future, I will be installing nux and epel. My understanding is that they do play well with each other and with base. Are there common useful C7 repositories that need help playing well with the aforementioned repos? Is there a FAQ or a FM on this? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

C7, encryption, and clevis
by m.roth＠5-cent.us 11 Jun '18

11 Jun '18

We've been required to encrypt h/ds, and so have been rolling that out over the last year or so. Thing is, you need to put in a password, of course, to boot the system. My manager found a way to allow us to reboot without being at the system's keyboard, a package called clevis. Works fine... except in a couple of very special cases. Those systems, the problem is that, due to older software, and *very* expensive licenses that are tied to a MAC address, I have to spoof the MAC address since my users got new(er) machines. Clevis is trying to contact its password server, using the *real* MAC address, but our DHCP has to serve the *spoofed* MAC address. I know, from trying, that I can't have two entries for the same system. Can anyone suggest a solution? mark

Convert from LVM
by Matt 08 Jun '18

08 Jun '18

I have a Centos 7 install using EXT4 on LVM. Its running as a VM inside KVM. Issue I have run into is that fstrim does not work due to the LVM. Without fstrim snapshots have gotten huge. Is there a way convert it from LVM to non-LVM without a complete reinstall?

A touch conused on context
by m.roth＠5-cent.us 07 Jun '18

Ok, we've got a set of directories bind mounted on our standard mount point for the web. The directory tree's been set with semanage fcontext -t -e /var/www <ourmountpoint>. In one of the websites under there is <site>/cgi-bin, and under *there are a couple of subdirectories, and a .dat file that is written to (I thihnk it's a counter, or whatever). Yet I see sealerts complaining that, if it was in enforcing mode, would not allow the .cgi that's in the cgi-bin write access on the file. What am I missing here? mark

git public web frontends
by Alice Wonder 07 Jun '18

07 Jun '18

Hello, Set up a CentOS 7.5 VM linode for git now that github has been bought. I'm not anti-microsoft but I'm worried they will make changes that I don't like (e.g. requiring ms account, changing billing, etc.) so I figured better take control now. Currently moving my private repos and have them set up in my home directory there, but my public repos - I want to set them up with a web interface so people can browse them etc. and do a git clone w/o needing authentication. I'll be putting those in /srv/git and using a different username than the account for my private git repositories. But... can anyone recommend a web front end? It doesn't need to be as fancy as github but it does need to parse markdown as all my documentation is in markdown. Thanks for suggestions. Preferably something that "just works" with CentOS 7. -=- What would be fantastic is if someone made some kind of federation type service similar to how Mastodon works that lets public git repositories that opt in be found without needing to be on a centralized server. But I doubt that currently exists.

Slightly OT : write bootable CentOS USB disk under Windows 10 and Mac OS X ?
by Nicolas Kovacs 07 Jun '18

07 Jun '18

Hi, I'm currently writing my fourth book about Linux, for the french editor Eyrolles. The book will cover Linux server basics for pros, and it will be based on CentOS 7. I have a quick question to those of you who use either Windows 10 or Mac OS X as their everyday desktop system. How do you write a bootable CentOS USB disk using either Windows 10 or Mac OS X ? I've googled this, of course, and there's quite a lot of possible solutions out there, so I'm curious about a more or less *orthodox* way of doing things. Me, I've been 100 % GNU/Linux since 2001, CentOS is running on my workstation and on my laptop, and I'm simply writing the ISO file to a USB stick using dd if=CentOS-XXXX.iso of=/dev/sdX.

Distributed System Monitoring
by Chris Olson 07 Jun '18

07 Jun '18

We have recently been assigned to help with the development of a system that will power non-computer/non-network devices located at various places within a 10,000 square ft facility. Most of these devices will operate on a fairly wide range of DC input power. The availability of surplus Cat-5 cable and the availability of low cost POE switches has been suggested as a method of powering these devices. There also appears to be some good, low cost installation options for all of the required system elements. The activity and health of the devices is directly related to their power consumption. Is there a standard CentOS feature or commonly used App that would facilitate monitoring the power being supplied by each of the individual POE switch outputs? Thanks in advance for any information shared.
