rpm requires logic
by Leon Fauster 14 Dec '15

14 Dec '15

Exists the possibility to define an RPM requires statement with a logic? Like: Requires: mysql-server OR mysql55-mysql-server MTAs like postfix have "Provides: MTA" to provide such facility. I do not see such possibility for DB packages ... Thanks -- LF

CentOS 7, NetworkMangler
by m.roth＠5-cent.us 14 Dec '15

14 Dec '15

This is annoying. I yum removed NetworkManager-wifi... and I'm still getting this junk in the logs: MetworkManager[7723]: <warn> error requesting auth for org.freedesktop.NetworkManager.enable-disable-wifi: (0) Authorization check failed: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus) Anyone have a clue as to what or why this is happening? I won't even mention the same for -wwan, and "sleep-wake". mark

tsocks or equivalent for CentOS 7
by Leroy Tennison 13 Dec '15

13 Dec '15

Does such exist? I looked for dante and couldn't find that. I found and tried using a version from CentOS 6 but it didn't work. If anyone can point me to an rpm (or set of same) I would most certainly appreciate it. Thanks.

Need firewalld clue
by Nicholas Geovanis 13 Dec '15

13 Dec '15

I don't really understand the intent behind firewalld. The RHEL7 Security Guide states "A graphical configuration tool, *firewall-config*, is used to configure firewalld, which in turn uses *iptables tool* to communicate with *Netfilter* in the kernel which implements packet filtering". So is the goal for firewalld to implement a GUI for iptables? What is the "value added" by firewalld? Thanks....Nick Geo

CentOS 7, NetworkMangler, and ipv6
by m.roth＠5-cent.us 11 Dec '15

11 Dec '15

We've started having a problem with a CentOS 7 server. It looses its IPv6 address, if I understand this issue correctly. We can get in, if we do ssh -4, though. In the logs, I'm seeing this about twice an hour: <warn> (pid 98466) unhandled DHCP event for interface ens3f0 Now, in googling, I get very few hits putting quotes around "unhanded dhcp exception" - in fact, the only one I found that seemed to talk about it was from someone's slackware box, where there was some sort of configuration, perhaps similar to ifcfg-<if>, and they were telling that person to remove it, because it conflicted with what Networkmanager was trying to do, leaving it in a confused state. Any thoughts? mark

To do this I am required to obtain such intimate personal knowledge of the internal workings of the distribution as to be able to identify these items as soon as they are introduced. naturally, I am also supposed to be able to immediately identify the negative impact of these things and prepare and present a cogent argument against their adoption or propose patches to correct the deficiencies that I believe that I have detected. I am to do this whilst running a CentOS installation that will not allow Fedora onto the premises. SO, no doubt, the intent is that I should run Fedora on my home systems and work diligently in my off hours to protect any future version of CentOS from that vantage. And of course, if I miss something then it is my fault for not having paid enough attention to that item.

Talking about the server community monitoring the Fedora development channel once every six months, or every day for that matter, is simply not going to change this. A handful of voices representing server installations, who by definition are not development types, has no hope of dealing with the incremental changes introduced every day by hundreds of people that use laptops as their primary development platform and all of whom have their own 'itch' to scratch. That is just the way it is in open source. The choice to go to Fedora for RHEL development was a commitment to the laptop environment, whether consciously made or not. And it is not in the control of RH to dictate this. If the Fedora developers take up tablets en masse then guess what?: We will end up with a tablet distribution. The OS distro we get is the consequence of the culture and environment predominant in the development community. This is neither good nor bad. It just is. Our firm has specific requirements which to date have been more than adequately met by RHEL and CentOS. But that seems to us to be changing in ways that no longer meet our expectations from a server based distro. A server based distro to us has certain characteristics that are orientated to long running processes and system uptimes measured in months if not years. I have given up counting how many times I have to reboot all of our CentOS servers in the past year because of updates. On the other hand I have this task running on a different server with a different OS: Priority = DS; Inpri = 8; Time = UNLIMITED seconds. Job number = #j3719. TUE, NOV 4, 2014, 2:04 PM. We do not need plug-and-play; or usb hot-swapping; or hibernation; or screen savers; or audio-video players; or power optimisation. All of which are worthy things in their own right and certainly have their place in computing. While these occasionally have proved convenient for me none are really necessary for a server host and their presence undoubtedly significantly increases the complexity and maintenance burden of the distribution. What we need is simplicity, stability, reliability, and consistency. What seems to be happening instead is feature-creep, software-bloat and increased coupling. And lest I be accused of 'wingeing' from the sideline I have been contributing to Open Source in a modest way since 1995, starting with Sendmail-8.7 on HP-UX. I just have limited time to give over to these things. The selection of RHEL for our primary platform was, in large part, to reduce the resources given over to managing the software. It would be ironic in the extreme were the reverse prove the case. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

no longer goes to standby when lid is closed
by Fred Smith 11 Dec '15

11 Dec '15

since I got the big bolus of updates from the CR repo a few days ago my netbook (AcerAspire One D255E) will no longer go to standby when the lid is closed. This was a Gnome desktopp installation with theh MATE desktop fromm EPEL. I've verified that the correct setting still exists in power manager but it persists in continuing to run when the lid closes. it WILL go to standby if explicitly told to do so from the shutdown dialog. Has anyone else seen anything like this?

when RedHat makes patches for only some versions
by Noam Bernstein 11 Dec '15

11 Dec '15

I guess this is really a RedHat, not CentOS question, but I’m hoping that someone here will be familiar enough with the upstream policy to have some useful information. How does RedHat decide which versions to release patches for, e.g. https://access.redhat.com/security/cve/CVE-2015-7613 <https://access.redhat.com/security/cve/CVE-2015-7613> which has only a RH7 erratum, not 6? And are they likely to eventually release a fix for this type of issue for RH6? thanks, Noam ----------------------------------------------------------- Noam Bernstein Center for Materials Physics and Technology Naval Research Laboratory Code 6390 noam.bernstein(a)nrl.navy.mil phone: 202 404 8628
