Dell Dimension 2400 W/Intel 845-G Video
by Mark LaPierre 04 Nov '14

04 Nov '14

Hey Y'all, I've been Googeling and experimenting for two days trying to find a way to deal with the Intel 845-G video chipset in this Dell Dimension 2400. First, it doesn't have a DVD drive so I have to install from a CD. When I try to boot into the Live CD I get a video error something like, Undefined video mode number: 317. It hangs at the splash screen. I was able to make a minimal install with the Minimal Install CD. I used yum to update and then install the desktop and X server. I managed to get it to bring up the desktop by adding nomodeset to the grub command line and by using the vesa driver but I can only get 640x480 resolution and the image is offset on the screen to the left and down. I tried a netinstall. It was looking good but the video bug crashed that too. I just swapped out the CD drive with another known good drive. Still no joy. I wasn't expecting that to make a difference so I wasn't disappointed when it didn't. There's a lot a cruft on the internet about problems with the Intel 845-G chipset but no solutions that work for me. Does anyone know how to get an successful installation on this hardware? -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Centos7 Annoyances
by david 03 Nov '14

03 Nov '14

Folks I'm sure the Centos team has done a yeoman's job getting Centos7 ready, and that the Redhat team has done marvels in creating rhel7, but here's a little voice from a personal hobbyist user. Background: ('ve been maintaining several remote servers since Redhat 6 days, migrating from that to Whitebox, then Centos, and things have been running as expected including the current version of Centos6. As an experiment, I've tried to play with Centos7 on an in-house virtual machine (VMWare on Win7), and have encountered a collection of annoyances greater than I've even seen. Below is a note about them. If someone has some elegant solution, I'd love to try, but Centos7 is still unusable for me. 1: Firewall changes The change in firewall technology forced a complete re-do of my scripts which maintain firewalls, respond to attacks, etc. I think I've programmed my way around the issues, but it wasn't easy. 2: Apache changes These were subtle, but again were solved. 3: Service -> systemd The change from object-oriented view of service: (service httpd restart) to function-oriented (systemctl restart firewall) seems to be unnecessary, and counter to the way stuff is generally done in the modern world. Nonetheless, it was possible to solve that with some adaptive script programming. 4) Something with Unknown lvalue 'ControlGroup' in section 'Service' I don't know what to do with this. I constantly get the diagnostic: [/usr/lib/systemd/system/rtkit-daemon.service:32] Unknown lvalue 'ControlGroup' in section 'Service' and attempts to browse the internet for solutions come across barriers that require some paid subscription to view. This is currently a progress-stopper. The messages I see deal with boinc, which does not show up on my system using "rpm -qa | grep -i boinc". 5) Sendmail is out, postfix is in. This is a huge change, since I had lots of scripts that tailored the Sendmail system for spam protection, dealing with SmartHosts that required SMTP-AUTH and others required weird configurations, etc. Whether this is working yet I don't quite know, but it seems the scripts can accommodate the change. 6) Installation I have no idea why, when using the net-install, one must explicitly turn on the network. It seems unnecessary. 7) Lack of 32-bit support I think I understand this. After all, 32-bit machines may become "unusable" when the clock overflows, but isn't that a few years away, and couldn't some solution be found, even if kludgy? Some of the 32-bit hardware was of very high quality, and still runs perfectly. I'd hate to spend a few hundred dollars each to replace all those systems. 8) And more ... I haven't got a server or desktop running to my satisfaction yet, so I don't yet know what pitfalls await. Any advice would be appreciated. David in San Francisco

I do not think it wise to have remi enabled by default. But, neither do I think it necessary to remove the repo altogether. Turning it off by default should suffice. Then remove whatever packages are causing causing the conflict as is suggested. The remi.repo need not be enabled to effect removals. Then try your update with remi out of the picture. -- *** E-Mail is NOT a SECURE channel *** James B.

Conflicts updating packages, hot to get ride of them without mess up all my OS?

Apparently I install some packages in the wrong way and now I'm having some problems updating my OS. This is what I'm doing: # yum update --enablerepo=remi,remi-php5 Loaded plugins: fastestmirror, security Setting up Update Process Loading mirror speeds from cached hostfile epel/metalink 2.3 kB 00:00 * base: centos.xpg.com.br * epel: mirror.globo.com * extras: centos.xpg.com.br * remi: mirror.pw * updates: centos.ar.host-engine.com base 3.7 kB 00:00 epel 4.4 kB 00:00 epel/primary_db 6.3 MB 01:55 extras 3.3 kB 00:00 mariadb 1.9 kB 00:00 nginx 2.9 kB 00:00 pgdg92 3.7 kB 00:00 remi 2.9 kB 00:00 remi/primary_db 1.0 MB 00:06 updates 3.4 kB 00:00 Resolving Dependencies --> Running transaction check ---> Package libevent.x86_64 0:1.4.13-4.el6 will be updated --> Processing Dependency: libevent-1.4.so.2()(64bit) for package: 1:nfs-utils-1.2.3-54.el6.x86_64 ---> Package libevent.x86_64 0:2.0.19-1.rhel6 will be an update ---> Package phpMyAdmin.noarch 0:4.2.10.1-1.el6.remi will be updated ---> Package phpMyAdmin.noarch 0:4.2.11-1.el6.remi will be an update ---> Package scl-utils.x86_64 0:20120927-8.el6 will be updated ---> Package scl-utils.x86_64 0:20120927-23.el6_6 will be an update ---> Package tzdata.noarch 0:2014h-1.el6 will be updated ---> Package tzdata.noarch 0:2014i-1.el6 will be an update ---> Package tzdata-java.noarch 0:2014h-1.el6 will be updated ---> Package tzdata-java.noarch 0:2014i-1.el6 will be an update ---> Package wget.x86_64 0:1.12-5.el6 will be updated ---> Package wget.x86_64 0:1.12-5.el6_6.1 will be an update --> Running transaction check ---> Package compat-libevent14.x86_64 0:1.4.13-1.rhel6 will be installed --> Finished Dependency Resolution But I get this error: Total size: 5.5 M Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Check Error: file /usr/lib64/libevent-2.0.so.5 from install of libevent-2.0.19-1.rhel6.x86_64 conflicts with file from package libevent-last-2.0.21-4.el6.remi.x86_64 file /usr/lib64/libevent_core-2.0.so.5 from install of libevent-2.0.19-1.rhel6.x86_64 conflicts with file from package libevent-last-2.0.21-4.el6.remi.x86_64 file /usr/lib64/libevent_extra-2.0.so.5 from install of libevent-2.0.19-1.rhel6.x86_64 conflicts with file from package libevent-last-2.0.21-4.el6.remi.x86_64 Error Summary ------------- So my question is how to get ride _secure_ of this conflicts and continue updating my system as I'm do it before this?

Restricting physical login access to specific nodes using PAM / NSS / SMB4 AD/DC
by Arun Khan 03 Nov '14

03 Nov '14

I am using SSSD to get user AUTH from a backend Samba4 AD/DC. For Linux clients sssd.conf is configured to query Samba4 AD based on LDAP/Kerberos i.e. the Linux clients have not done a Domain join. Physical console logins -- things are working fine with changes to NSS and PAM (tool authconfig) for domain User AUTH on Linux and Windows clients. However, I want to restrict access to certain machines to users of a specific group e.g. HR. I guess this is possible on Windows clients with group policies. Is the same possible on CentOS (Linux) workstations. TIA, -- Arun Khan

legacy-x
by Negative 03 Nov '14

03 Nov '14

I recently installed Centos 7 on a new desktop, and I intended to put XFCE on it, but I think I made a mistake by choosing the Legacy-X group, and now I'm puzzled as to what I have. I thought my first boot would be into runlevel 3, but I got a gui that looks like an odd mix of Gnome 2 and KDE. The anaconda logs show a group install of gnome-desktop and legacy-x, plus a lot of KDE stuff. The mix looks ok, and handles my dual monitors fine, but there are some prefs that simply don't work -- one important bit is that my monitors mostly (but sometimes) go into power save, and I cannot find an option to do it manually. One option now is to install XFCE, but I don't know how that works. Maybe better to uninstall gnome-desktop and legacy-x and just go with XFCE, and I'll wind up with a coherent environment. Btw, I've tried both Gnome 3 and xfce on an old machine in fedora, and much prefer XFCE. (Luckily, we have choices.) Any guidance?

Evolution 3.8.5 imap iCloud will not connect
by Stan Cruise 02 Nov '14

02 Nov '14

There is a problem in Evolution 3.8.5 due to changes icloud made to their servers. It disallows imap connections due to authentication issues. The following link to gnome.org indicates that a patch is available for Evolution 3.10 (the problem does not occur in 3.12). https://mail.gnome.org/archives/evolution-list/2014-October/msg00113.html Milan suggests "Ask your distribution to use the patch from the [1] and provide an update for you." Is there any chance of this for Centos 7, as Evolution is currently rendered inoperable with iCloud imap. Bugzilla ref: *Bug 1153052* <https://bugzilla.redhat.com/show_bug.cgi?id=1153052> -Evolution 3.10.4 not able to use TLSv1 or higher (only SSLv3) Regards, Stan

Hello All, the update to Centos6.6 got interrupted on a laptop. I then did this: package-cleanup --cleandupes yum-complete-transaction and remove and reinstall the latest kernel. I now get an error message when booting: /dev/mapper/vg_jvermeulen-lv_home does not exist. I can boot into single user mode and run all commands. in fdisk -l .....lv_home is not listed. How can I re-add this? I do have a backup of this machine. Thanks for any help.
