SELinux C7 audit
by Alessandro Baggi 06 Jul '16

06 Jul '16

Hi list, I'm studying SELinux on my workstation and for this I've enforced. In a first time selinux was permissive and when switched to enforcing I had relabel some things. Due to my "nescience" about selinux and what I must configure, I'm waiting avc denied for specified services. Until today, I've configured successfully httpd, smbd. Today I've noticed that my bacula system does not work due to selinux denied because when bacula try to run pre/post job script I get access denied due to differences about context. Bacula is on bacula_t and in pre script I call commands in other context like: systemd_systemctl_exec_t ... (and other) Reading from RHEL DOC (SELinux Guide) I can accomplish to remove denied access using audit2allow and creating TE rules. I've runned: grep systemctl /var/log/audit/audit.log | audit2allow -M pol and I got 2 files pol.pp (compiled) and pol.te. pol.te reports: require { type systemd_systemctl_exec_t; type bacula_t; class file execute; } #============= bacula_t ============== allow bacula_t systemd_systemctl_exec_t:file execute; Loading this policy things "will work". Now this problem is solved by audit2allow and not by me. I don't know what is necessary to make pre/post job script to get work done. What are the meaning of rules on pol.te and why bacula can't do transiction between context? Hope in help. Thanks in advance.

how to set/add environment variables and make file search priority on centos
by qw 05 Jul '16

05 Jul '16

Hi, I'm using centos 6.8. In order to build gstreamer 1.8.2, I install some new packages, such as python 2.7 and yasm. And cerbero is the build system for gstreamer, and downloads some new packages from network and build them, such libtool, glib. All new packages are downloaded, built and installed in my custom directory. I want cerbero use the new packages in my custom directory. It mean that, linux will search my custom directory first, and will search others if target program or lib is not found. How to make search priority for programs, static libs, shared libs, and pkgconfig files? Thanks! Regards Andrew

netbook screen suddenly goes black
by Fred Smith 02 Jul '16

02 Jul '16

Hi all! I'm running an up to date Centos-7 on my Acer Aspire One netbook. have been for, well, ever since C7 was released. Just had an event today that also happened 2 or 3 times with earlier systems installed, but I never pursued it. What happens is that suddenly while working away on the desktop the display suddenly goes black... not black as in turned off, I can see that the backlight is still on, but no image is displayed. Nothing I can do fixes it except a reboot. I've tried CTRL-ALT-BKSP, CTRL-ALT-DEL, alt+printscreen+r+e+i+s+u+b. none of them do anything noticeable. I've been looking at system logs and don't find anything that gives me a clue what is going wrong when that happens. neither dmesg, /var/log/Xorg*, nor /var/log/messages contins much. I've tried digging thru "man journalctl" and ultimately reading thru the output of journalctl with no arguments. Can anyone of you provide further hints on what I should be looking for or at? thanks!

Securing RPC
by Leon Vergottini 01 Jul '16

01 Jul '16

Dear Community I hope you are all doing well. Recently I have been receiving several complaints from our service provider. Please see the complaint below: A public-facing device on your network, running on IP address XXX.XXX.XXX.XXX, operates a RPC port mapping service responding on UDP port 111 and participated in a large-scale attack against a customer of ours, generating responses to spoofed requests that claimed to be from the attack target. Please consider reconfiguring this server in one or more of these ways: 1. Adding a firewall rule to block all access to this host's UDP port 111 at your network edge (it would continue to be available on TCP port 111 in this case). 2. Adding firewall rules to allow connections to this service (on UDP port 111) from authorized endpoints but block connections from all other hosts. 3. Disabling the port mapping service entirely (if it is not needed). Unfortunately, I cannot disable NFS which lies at the root of this problem. In addition, I am struggling to find a proper tutorial of moving NFS from udp over to tcp. May I kindly ask you to point me in a direction or provide me with ideas on how to nail this thing in the .... Kind Regards Leon

by qw 01 Jul '16

01 Jul '16

Hi, I'm trying to build gstreamer sdk on centos 6.7. When configure is run for 'gstreamer-1.8.2.tar.xz' on centos 6.7, error messages are reported as below: checking for GLIB... no configure: Requested 'glib-2.0 >= 2.40.0' but version of GLib is 2.28.8 configure: error: This package requires GLib >= 2.40.0 to compile. The command of 'yum install glib*' can only update glib to glib-2.28.8. How to update glib to the version of >=2.40.0 on centos 6.7? Thanks! Regards Andrew
