Centos 6.9 Ipset broken after installing xtables-addon
by George Travan 07 Nov '18

07 Nov '18

I have managed to break my system by installing xtables-addons-1.37. Now ipset does not work. "Kernel error received: Invalid argument" I built the addon from source on my centos 6.9 system as per instructions for centos 6. It looks to me that xtables-addons has built and installed a ipset-4 extension due to my kernel: 2.6.32-754.6.3.el6.x86_64 I already had ipset v6.11 installed and now both do not work. The README indicated that I need a kernel > 2.6.35 which I presume is the problem. This now has become a major problem for me as I rely on ipset. Anyone suggest what I might do to fix this problem? Thanks, /Geo

polkit-gnome-0.106 with CentOS 7.5 ???
by Kay Schenk 04 Nov '18

04 Nov '18

What can anyone tell me about the polkit-gnome package that came with CentOS 7.5? Looking at the Fedora pack for the same, it seems like I'm missing pieces of this package. Re: https://rpmfind.net/linux/RPM/epel/7/x86_64/Packages/p/polkit-gnome-0.106-0… I start my gui session with startx instead of GDM. I am having a lot of authentication issues at the moment. I am somewhat familiar with dealing with polkit but mostly things are not working well at all. On an older version of openSUSE I once used with systemd, I started up a kde-polkit-integration app as part of my X session init, in a local .xinit file. Should I do the same with the supplied polkit-gnome provided? Any insights much appreciated. Thanks. ------------------------------------------ MzK "Less is MORE."

reading old dump backups from 2009
by Nataraj 04 Nov '18

04 Nov '18

I have and old dump format backup done under fedora 7 which is stored on disk and has an sha256sum file that indicates there are no data errors in the backup file. When I try to read the file with restore under CentOS 6, I get the following error: cat /etc/redhat-release CentOS release 6.10 (Final) restore tvf u1_l0_04-29-09_md1.dump Verify tape and initialize maps Input is from a local file/pipe Checksum error 20311110402, inode 0 file (null) restore: Tape is not a dump tape I have another copy of the backup on another disk with the same checksum and it gets the same error as well. Here's a log file from when the backup was done back in 2009: DUMP: Date of this level 0 dump: Wed Apr 29 09:24:36 2009 DUMP: Dumping /dev/md1 (/u1) to u1_l0_04-29-09_md1.dump DUMP: Label: /u1 DUMP: Writing 10 Kilobyte records DUMP: Compressing output at compression level 2 (bzlib) DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 95176885 blocks.

Any other suggestions on how to read this backup would be helpful. Thank You, Nataraj

inquiry about limitation of file system
by yf chu 04 Nov '18

04 Nov '18

I have a website with millions of pages. We often deploy our websites on centos with Nginx and Apache Http Server as HTTP Web Server. I am very worried about the performance of web server if the amount of pages is very very large. I wonder whether the performance will be affected if there are too many files and directories on the server. Besides, our bugdet is limited. We do not want to deploy too many Servers and use other file system such as GFS. So I want to know the limitation of centos file system and how should I handle this issue.

fingerprint reader on C-7 ???
by Fred Smith 03 Nov '18

03 Nov '18

Hi all! I just got a new (to me) used laptop (HP EliteBook 8530p) and find that it has a fingerprint reader. Wondering if it could be made to work for me (Centos-7) I did a lot of googling (well, actually duck-duck-go-ing) and found a ton of hits on either setting it up in Windoze, or others wondering if it can be used in Linux. Some info on setting it up in Ubuntu, and a couple of pages on setting it up in Fedora, pages that were ten years old, or so. Found an academic paper on a group that wrote portable tools in Java that allegedly enable it in a cross-platfor manner, but not the software itself. Does anyone here have any better information on if it is possible, and if so, how? thanks in advance!

PostgreSQL port accessible even though it should be blocked by firewall

netinstall problem -- corrupt alsa-utils-1.1.0-10.el6.i686.rpm?
by Alain.Cochard＠unistra.fr 31 Oct '18

31 Oct '18

Hello. I try to install from the netinstall iso file. Everything works as I expect up to the screen where I have to choose between "Desktop", "Minimal Desktop", "Minimal", etc. If I choose either "Desktop" or "Minimal Desktop", I have a pop up saying "Installation Starting" with "Starting installation process", and, about a few seconds afterward, an "Error" pop up that says: The file alsa-utils-1.1.0-10.el6.i686.rpm cannot be opened. This is due to a missing file, a corrupt package or corrupt media. Please verify your installation source. If I choose "Minimal", this is the same except that instead of the alsa*.rpm, it is iputils-20071127-24.el6.i386.rpm. I have successfully used this installation procedure in the past, literally tens times (last time in January). Since it says "verify your installation source", I have now tried again with CentOS-6.10-i386-netinstall.iso CentOS-6.9-i386-netinstall.iso on two different USB sticks, written with unetbootin and livecd-iso-to-disk on two different computers. I also have a DVD with some former CentOS version (perhaps 6.4). I have tried the installation on 3 different computers (on one of which the procedure worked in the past). Every time it is the same. NB: during the installation process, the URL I enter is http://mirror.centos.org/centos/6/os/i386/ Any "chance" there is a problem on the CentOS side? Otherwise, what could I be doing wrong now? Thank you very much.
