C7: How to configure raid at install time
by Fred Smith 27 Nov '15

27 Nov '15

Hi all! I'm still on C6. I'm using a RAID1 configuration (Linux software RAID) and I'd like to either use the same one, or possibly configure it on new drives (larger) when I upgrade to C7. (I'm really feeling the need to move off C6.) But it isn't at all obvious how one would do a new RAID1 setup in Anaconda, and I don't find any user reports or other info on this in the WIKI or forums (fora, properly, if I recall my high school Latin). Can anyone provide (or give pointers to) a good recipe for doing this? thanks! Fred -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ---------------------------- Do you not know?

install rrdtools-devel / rrdtool-perl
by Leandro 26 Nov '15

26 Nov '15

Hi guys , Im have some problems installing the following packages: rrdtool-devel rrdtool-perl Before we moved to centos/rhel7 it was a simple task, just doing: yum install rrdtool rrdtool-devel and rrdtool-perl was enough. Now, I only can install the rrdtool package but not rrdtool-devel and rrdtool-perl. I tryed adding some repos, but I think I added wrong ones. Also tryed downloading and installing packages with rpm -ivh but there is allwais a missing dependence. Can you help me ? Thanks.

OT: bareos, Windoze, beating head on wall
by m.roth＠5-cent.us 26 Nov '15

26 Nov '15

Again, I'm posting here because when I tried their mailing list, I didn't get much response. I'm trying to do a restore, from my CentOS 6 box, to a WinDoze box. The restore command is *not* user-friendly if you just want to restore a few files. And it gets weird.... First, I have to mark my path first - I don't just see it with ls. Then, when I do an ls, in c:/Users/<username/Documents/, it shows *MATLAB *My Music *My Pictures *My Videos *Visual Studio 2005/ *Visual Studio 2008/ *desktop.ini *None* of which are there. All that's there are teo files, testfile.bak and testfile.txt. MATLAB is in some other user's directory.... Here's the fileset spec from bareos-dir.conf FileSet { Name = "citdcbhebronset" Include { Options { Signature = MD5 # calculate md5 checksum per file Ignore Case = yes } File = "c:/Users" } } Anyone have any clue as to what I'm doing wrong? Googling - a lot of it - gives me 90% the bareos docs, and very little else. mark

Glibc vulnerbality CVE-2015-1781
by Venkateswara Rao Dokku 26 Nov '15

26 Nov '15

Hi, We are using CentOS 5.5 as a base OS for one of our products.The version of Glibc we are using was glibc-2.5-123.el5_11.1. We wanted to see whether this glibc is vulerable to CVE-2015-1781. I have gone through re-documentation & came across the following link https://access.redhat.com/security/cve/cve-2015-1781 In the link it is mentioned that, the CVE will not be fixed in Red-Hat 5 version. What does that mean? I mean, whether the RedHat 5 is vulnerable & fix is not available or RedHat 5 is not vulnerable, hence the fix is not given? Thanks for the info. -- Thanks & Regards, Venkat

Help with Intel 6235 Wireless on CentOS 7 (pointer to good reading?)
by Valeri Galtsev 25 Nov '15

25 Nov '15

Dear Experts, I would like to ask your advise on good reading about how to add WiFi device, and how to control its settings on CentOS. Sounds really dumb, but this is what I am NOT able to do on CentOS 7 what I was able to do in the past, beginning somewhere since RedHat 5 or 6, through Fedora and up to CentOS 6. In brief: my card is Intel 6235; CentOS 7 (fully updatted), latest kernel (3.10.0-229.20.1), relevant Intel firmware version for my card is in /lib/firmware (together with large bunch of other Intel WiFi firmware), relevant modules are loaded in kernel: iwlwifi iwldvm mac80211 cfg80211 "/sbin/ifconfig -a" shows my device in the list renamed to wlp3s0 (according to PCI slot numbering I figure), dmesg shows device brought up successfully detected and renamed as above. lspci shows device with its correct full name (Network controller: Intel Corporation ... 6235" Now comes the fun part (no, troublesome for me part). When I click on the NetworkManager Applet in right top corner, there are no WiFi devices. I go to Network Settings from there. My device is in the list under name "PCI Unknown". I click on that, the device is described as "unmanaged", and there is no way to make changes to the contrary to other devices (correct MAC address is displayed). OK, I assume I just need to declare device as NM_CONTROLLED. There is no relevant /etc/sysconfig/ifcfg-wlp3s0 - where I know I can declare that. I use "nmtui" to add configuration, then add to ifcfg-wlp3s0 NM_CONTROLLED="yes" line. Reboot. Still the same. Just for comparison I booted Ubuntu 14.0.4 x86_64 live CD. Yes, it can see my wireless, and I can connect to WiFi networks. Kernel is just a notch newer (3.13.0.24) which shouldn't matter according to Intel information which kernel versions this device is supported in. List of relevant kernel modules loaded by ubuntu is exactly the same. I don't see anything weird like the need to separately load firmware as kernel module (yes, indeed I'm going nuts, that would be "freebsd-ism" I guess). I do not want to have Ubuntu (or Debian which likely will work out of the box too) on this laptop. So, apparently I need a pointer to good reading on how do we do it on CentOS 7 "dirty way" - when "click here, choose in menu that" doesn't work. Thanks a lot for your advises!

OT: Replacing Venerable NAS
by Tim Evans 25 Nov '15

25 Nov '15

I have an original-label Infrant (now NetGear) ReadyNAS storage appliance that's been running for 8+ years. Except for replacing its power supply, it has not skipped a beat in all this time. I use it primarily as a backup device (via NFS) for a couple of Linux machines, (via SMB) for a couple of Windows PC's, and (via ftp) for web sites at my hosting provider. SMART+ reporting shows ~75K hours operation, with zero sectors reallocated, on each of the four disks. I'm thinking I should be looking for a replacement, even with all this good info/luck. Would like to hear recommendations here. Besides the ReadyNAS, I have worked with a Thecus NAS (don't recall model). What are the features I should look at? Thanks. -- Tim Evans |5 Chestnut Court 443-394-3864 |Owings Mills, MD 21117
