SELinux vs. logwatch and virsh
by Bill Gee 15 Aug '14

15 Aug '14

Hello everyone - I am stumped ... Does anyone have suggestions on how to proceed? Is there a way to get what I want? The environment: CentOS 7.0 with latest patches. The goal: I want logwatch to include a report on the status of kvm virtual computers. The problem: When run from anacron, SELinux denies permission for the virsh utility. Here is a portion of the logwatch output: --------------------- KVM libvirt status report Begin ------------------------ Date Range: yesterday /etc/logwatch/scripts/services/libvirt: line 15: /usr/bin/virsh: Permission denied ---------------------- KVM libvirt status report End ------------------------- If I "run-parts /etc/cron.daily" from a root console, it all works. Same if I run "logwatch" from a root console. I set SELinux to permissive and that allows virsh to run. Therefore I know it is something to do with SELinux. The logwatch script is: #Lots of comments /usr/bin/virsh list --all I see the selinux security context of virsh is system_u:object_r:virsh_exec_t:s0 while logwatch.pl runs as system_u:object_r:logwatch_exec_t:s0 As I understand it, selinux does not permit having multiple type settings for a file. Any file can have exactly one type setting. I ran this command hoping it would add another type to the virsh program. semanage fcontext -a -t logwatch_exec_t /usr/bin/virsh semanage fcontext --list /usr/bin/virsh | grep virsh /usr/bin/virsh all files system_u:object_r:logwatch_exec_t:s0 /usr/bin/virsh regular file system_u:object_r:virsh_exec_t:s0 /usr/sbin/xl regular file system_u:object_r:virsh_exec_t:s0 /usr/sbin/xm regular file system_u:object_r:virsh_exec_t:s0 Semanage did add the new type, but that did not fix the problem. Virsh still gets "permission denied" when logwatch tries to run it. Thanks - Bill Gee

Centos 7 as gateway - UDP performance is busted/awful?
by Tom Horsley 15 Aug '14

15 Aug '14

I just replaced a dead system disk on my KVM host that was running an ancient fedora 13. Since centos 7 was available, I decided to go with it to get some long term stability. The problem is that NFS mounts inside the virtual machines don't work for spit when talking to older NFS servers that must speak UDP. Is there something about UDP traffic that requires tweaks I don't know about for centos 7 to serve as a gateway machine? I've got the ip forwarding settings and other sysctl stuff that was set in the old fedora 13 system. I've got the bridges defined that same way as the old f13 system. I've got TCP stream connections working flawlessly, it is just the UDP traffic that seems to barf. Does this strike a familiar note with anyone? When I run wireshark on the KVM host machine, I see NFS packets retransmitting a lot and I also see ICMP messages about Destination Unreachable, Fragmentation Needed. (I don't know what any of it means though :-). This is an intel motherboard with these ethernets: 04:00.0 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01) 04:00.1 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01)

CentOS 7 - Firewall always allows outgoing packets?
by Neil Aggarwal 14 Aug '14

14 Aug '14

Hello all: I am looking at the documentation of the new firewalld service in CentOS 7. It looks like no matter what I configure with it, outgoing connections are still going to be allowed. That does not seem very secure. I always set my servers to default policy of DROP for everything incoming and outgoing and then add rules to allow very specific traffic through. Is this possible using the new firewalld service or should I disable it and go back to using iptables? Thanks, Neil -- Neil Aggarwal, (972) 834-1565 We lend money to investors to buy or refinance single family rent houses. No origination fees, quick approval, no credit check.

slow i/o with a raid 50 on a 3ware controller
by Chuck Campbell 14 Aug '14

14 Aug '14

I have a raid 50 array on a 3ware controller. The box is running centos 6.5 and the file system is ext4. I'm going to try some other filesystems, but could anyone suggest any alternative raid setups as well as stripe sizes I should try? The old server uses the same controller on a centos 5.10 setup, using ext3, and it performs much faster i/o. The old 3ware setup is raid 5. -chuck -- ACCEL Services, Inc.| Specialists in Gravity, Magnetics | (713)993-0671 ph. | and Integrated Interpretation | (713)993-0608 fax 448 W. 19th St. #325| Since 1992 | (713)306-5794 cell Houston, TX, 77008 | Chuck Campbell | campbell(a)accelinc.com | President & Senior Geoscientist | "Integration means more than having all the maps at the same scale!"
