A newbie question about searching an installed packet
by Pierre Malard 09 Nov '18

09 Nov '18

Hi, I’m french and literally one. So I’m not really easy with Sheakespeare language. So, accept my apologies. As write in subject, I’m a newbie about CentOS an all RedHat declines. I wrote a Shell script for ours Debians (all sort of Debian like) which verify which packets are present before running. I thought I had found an equivalent with « yum list installed | grep <packet> » command but I have sometime alerts about a lock because an other instance of « yum » is running. I don’t understand why a simple « yum list » impose that! I suppose, like with « aptitude search », it is an understanding scorie. I’m sure there is an other way to do what I want to do: just verify if a packet is, or not, installed. Help?

Desktop files change?
by david allan finch 08 Nov '18

08 Nov '18

Hi, Does anyone know if they changed the way that desktop files for apps work? It seams that inside your start script you can no longer change your scripts directory. Does it now call some form of restricted shell? Anyone know where you can track these changes?

command in kickstart file to write disklabel?
by Valeri Galtsev 08 Nov '18

08 Nov '18

Dear All, At some point after release of CentOS 7 (though this thing might have started before, it is just when _I_ noticed it) I discovered that if I stick into machine drive without disk label, and then do kickstart installation, the command in kickstart file clearpart --initlabel does not work. Even worse: if I just use GUI installer the drive is not listed between available disks. If I switch in the same installer to some virtual console Ctrl + Alt + F2 I can see that the kernel installer run under definitely sees the drive: /dev/sda is present. It must be an issue beaten to death, but somehow my search ability fails on this particular one (I am not "googling" but "duckduckgo-ing", though this shouldn't matter the problem as usually must be myself). Can someone suggest something? I know it is trivial to just create disklabel before sticking drive in machine, but once I'm using kickstart, any need in separate manual steps feels really lame. Thanks a lot for all your help in advance!

Yum and proxy settings
by Vic Chester 08 Nov '18

08 Nov '18

I have configured yum to use a proxy via the yum.conf file by adding: proxy=http://myproxy.com:8080/ What I noticed when running yum check-up date is that some requests are going through the proxy while the system seems to be trying to resolve the domains of other hosts in the repo and trying to establish direct connections to them instead of going through the proxy. Can anyone explain this behavior?

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 05 Nov '18

05 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 05 Nov '18

05 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.
