VNC on centOS
by Hersh 11 Dec '15

11 Dec '15

Hi, I have recently installed centOS 7 and trying to start vnc server on it. Somehow, I am unable to make vncserver working. I have modified iptable rules and xstartup file but it did not help. Has anyone else faced this problem earlier? Any help would be appreciated. Regards Hersh

USB devices - libgphoto2 - PTP - hplip
by Michael H 10 Dec '15

10 Dec '15

Hi, Posting this again as it has been drowned. can anybody assist? ------------------------------------------------------------------ Hi All, I'm trying to disable USB storage devices in Centos7.1.1503. I've setup udev rules to block all usb devices and then additional rules to allow specific vendors / products to be used (mainly keyboards and mice). This is all working perfectly. cat /etc/udev/rules.d/01-usblockdown.rules # Block all USB devices ACTION=="add", SUBSYSTEMS=="usb", RUN+="/bin/sh -c 'for host in /sys/bus/usb/devices/usb*; do echo 0 > $host/authorized_default; done'" # Allow devices # Keyboards ACTION=="add", ATTR{idVendor}=="04f3", ATTR{idProduct}=="0103" RUN+="/bin/sh -c 'echo 1 >/sys$DEVPATH/authorized'" ...... Now I'm testing against mobile devices and when I connect an Asus mobile telephone it's mounting the camera using PTP even though the device is not allowed in my udev rules. I removed libgphoto2 which has now stopped the PTP from automounting. My issue is that I require hplip on my systems for certain printer drivers and this package was removed along with libgphoto2. I added an 'exclude=libgphoto2*' to my /etc/yum.repos.d/CentOS-Base.repo and installing hplip now fails on dependencies. Is there a method of disable libgphoto2 PTP without having to remove the package? or can I create further udev rules to stop PTP mounts? thanks in advance, Michael

CentOS 6, bareos, kerberos?
by m.roth＠5-cent.us 09 Dec '15

09 Dec '15

After upgradeding to bareos 15.2, which also has a web ui, thereby making it usable (since the command line tool, bconsole, does not have a paging mechanism, and its sytax for choosing files to restore is, let us say, arcane), I've got another question: is *anyone* using bareos with kerberos? I see that they have in alpha(?) tls support, which isn't a great idea, given the recent vulnerabilities.... If you've figured out how to use kerberos, rather than hard-coding a password in the console configuration, I'd love to hear it. mark

Which form also is how I get this list's messages. Thus the delay in my responses. However, to describe the Server List as an active forum for discussion would be somewhat overstating things. I have not received anything from it as yet in December and the total volume of traffic on that list in November was very light. I am not sure in what way you envisage additional involvement is to take place. I have been bitten by things done in Fedora that only have any use on a laptop and that should never have been allowed into a server distribution. But I cannot see how I would have been aware of them until they manifested themselves on equipment under my care. By which time it is rather too late to influence the decision to include them. Automatically powering down NICs comes to my mind; due the rather nasty consequences that resulted. The difficulty is that with Free and Open Source Software you are only going to see features that are of some immediate use to the writers; or whose value has already been entrenched such that it is difficult if not impossible to dispense with. Clearly, power saving features are of some interest to people that run their systems on batteries. However, there are batteries, and then there are batteries. We occasionally run run on batteries too. It is just that ours are measured in kilovolt-amp hours. Having a server distro configured by default to turn off a NIC because it has not had traffic for fifteen minutes is not going to save us enough power from now to the end of eternity to warrant the disruption that little 'feature' cost us when it was first encountered. The move to Systemd, and all the controversy that decision has generated, also provides 'features' whose benefits appear to me be be aimed principally at users who shut their systems off every day. These benefits are of far less value to people who measure uptime in months or years, while the discomfort, and expense, of this change must be borne regardless. Systemd will eventually be accepted or rejected on its own merits. I am not interested in debating them here since I have nothing upon which to base an opinion one way or the other. But it can hardly be denied that forcing highly qualified people to expend time, a very limited resource in my experience, to learn yet another way to start a computer system, without providing any readily discernible benefit to them, is not likely to engender much in the way of sympathy. We went to RedHat and ended up on CentOS because of its server orientation. Which to us implied something more than simple compatibility of the software components. If RedHats's intent is to end up as a laptop distro then we will probably part ways at some point. We have a laptop distro that works well for us. It is called OSX. And the hardware is pretty good too. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

CentOS 6 up-to-date 2.6.32-573.8.1.el6.x86_64 Gigabyte GA-Z68P-DS3 on-board audio BIOS disabled. Intel I5 Pny 550Ti video Envy 24HT pci audio module I want to use the fiber in/out of the audio card, but it is not listed in System/Preferences/Sound/Hardware, only the HDMI is available. It was installed in the pci slot when the system CentOS 6.0 was installed. I have searched all over Google, but can't find a solution. Does anyone have a solution for this problem ?

Hello, i have a little question. My system: ip route: 0.0.0.0/1 via 10.8.0.5 dev tun0 default via 192.168.2.1 dev br0 proto static metric 425 10.8.0.1 via 10.8.0.5 dev tun0 10.8.0.5 dev tun0 proto kernel scope link src 10.8.0.6 88.198.140.127 via 192.168.2.1 dev br0 192.168.2.0/24 dev br0 proto kernel scope link src 192.168.2.101 metric 425 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 traceroute gmx.de traceroute to gmx.de (213.165.65.60), 30 hops max, 60 byte packets 1 Speedport.ip (192.168.2.1) 0.578 ms 0.662 ms 0.859 ms ^C [root@h1 ~]# traceroute spiegel.de traceroute to spiegel.de (62.138.116.3), 30 hops max, 60 byte packets 1 10.8.0.1 (10.8.0.1) 35.009 ms 34.982 ms 34.956 ms Why the routing is different, in first case over br0 in second over the vpn device? How can i disable "push default route" from the server-directive on client-side in OpenVPN? I want, that only traffic, incoming over tun0 routing back over tun0. Is this possible with firewalld-cmd?

yum errors
by Wes James 08 Dec '15

I have inherited centos 6.3 and 6.2 vms in an esxi environment. When I do yum provides ntpd on the 6.3 box I get a lot of errors like: Loaded plugins: fastestmirror, presto Loading mirror speeds from cached hostfile * base: mirror.unl.edu * extras: mirrors.cmich.edu * updates: mirror.steadfast.net http://mirror.unl.edu/centos/6.4/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404" Trying other mirror. http://mirror.ash.fastserv.com/pub/linux/centos/6.4/os/x86_64/repodata/repo…: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404" Trying other mirror. http://mirrors.einstein.yu.edu/centos/6.4/updates/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://mirrors.einstein.yu.edu/centos/6.4/updates/x86_64/repodata/repomd.xml: (28, 'connect() timed out!')

Trying other mirror. Why am I getting these errors? I installed 6.4 in virtualbox and the .repo files seem the same, except the 6.3 box didn’t have a fastback.repo file. Also why is it looking at 6.4 repos above? When I see: cat /etc/redhat-release CentOS release 6.3 (Final) i.e., this box is 6.3. Shouldn’t it be looking for 6.3 repo info? Thanks, -wes

Version numbering vis a vis CentOS and RHEL

However, there are those of us who use CentOS in a very large enterprise environment. That is, in fact, the intended audience of the whole distro. When there is a "new version" of Red Hat (and I know that means nothing with hundreds of constantly updating packages; however, my bosses don't get that), and hence CentOS, there is a huge amount of work that needs to be done in a typical enterprise. These include, but are not limited to: - setting up a new internal-only mirror of the distribution - setting up a new tftp/PXEboot/kickstart environment for network installs. - Editing several install scripts to match the new environment - Testing all these changes - Checking that all security recommendations/edicts from a higher authority (e.g. the US Government), which are also based on the "version", are followed - Checking that all commercial software supports the release (most of these use "RHEL X.y", what is that in CentOS now?) - Trying to get support from commercial software when the "version numbers" don't match - Coordination of other repositories (e.g. EPEL) is based on the "version", how does that work now? All of these things ran in parallel with the RHEL release cycle, and the work could be done at the same time. That was the overriding philosophy of CentOS, "we are a recompile of RHEL." Now, the impression is (rightly or wrongly, it doesn't matter to me) CentOS is totally becoming a separate Linux distro, and needs to be treated as such. And that has huge implications for system administrators in a large environment. Huge. There are answers to all these questions, but there is a lot of confusion that's been generated by this seemingly cosmetic change in version numbers. I've checked, and there was no,"We're considering creating this basic difference from RHEL, how will this affect you?" on this list, or the website, etc. From our viewpoint, it was sprung on us out of nowhere, and now were being told "deal with it, or leave." It sucks. -- Matt Phelps System Administrator, Computation Facility Harvard - Smithsonian Center for Astrophysics mphelps(a)cfa.harvard.edu, http://www.cfa.harvard.edu
