low latency kernel?
by Les Mikesell 02 Apr '15

02 Apr '15

Someone recently posted on the x2go list that he had a problem with jerky videos playing remotely on Ubuntu, but solved it by installing a low latency kernel that was available as an alternative. That made me curious as to whether CentOS has an equivalent - or a way to build something similar. -- Les Mikesell lesmikesell(a)gmail.com

Centos 7 License???
by David A. De Graaf 01 Apr '15

01 Apr '15

Today I did a yum upgrade to my kvm'ized Centos 7 test machine (perhaps a bad day to do such a thing) and received new kernel vmlinuz-3.10.0-229.1.2.el7.x86_64, among many other things. When I rebooted, I was asked to confirm (or renew, or some such) my license. My LICENSE ??? I was booting in text mode and the actions required were a) unfamiliar, and b) hard to understand. As I recall, I had to read the EULA - a worrisomely Microsoftian demand - and accept it. Of course, the terms were pretty benign. Then I had to continue. I can't remember the exact language. Of course, now when I reboot, all this cruft is gone. Is this a cute April Fool joke? If not, WTF is going on? -- David A. De Graaf DATIX, Inc.

SEmodule dependency hell.
by James B. Byrne 01 Apr '15

01 Apr '15

I want you all to see what I went through trying to simply reassign (unsuccessfully) the context of a well-known port. To the best of my ability to recall none of the packages mentioned below are even installed on the host in question. Why are these dependices preventing me from removing a disused SELinux policy. I have done exactly that, reassign port contexts, in the past without encountering this situation. So it has to be a recent development. I am not against SELinux. We use it extensively. But this is not security it is simply BS. It is stuff like this that causes people to say just turn selinux off altogether. semodule -r apache libsepol.print_missing_requirements: awstats's global requirements were not met: type/attribute httpd_log_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r awstats semodule -r apache libsepol.print_missing_requirements: bugzilla's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r bugzilla semodule -r apache libsepol.print_missing_requirements: cobbler's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r cobbler semodule -r apache libsepol.print_missing_requirements: collectd's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r collectd semodule -r apache libsepol.print_missing_requirements: git's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r git semodule -r apache libsepol.print_missing_requirements: gpg's global requirements were not met: type/attribute httpd_sys_content_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r gpg semodule -r apache libsepol.print_missing_requirements: mediawiki's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r mediawiki semodule -r apache libsepol.print_missing_requirements: munin's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r munin semodule -r apache libsepol.print_missing_requirements: nagios's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r nagios semodule -r apache libsepol.print_missing_requirements: w3c's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r apache libsepol.print_missing_requirements: webadm's global requirements were not met: type/attribute httpd_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r webadm semodule -r apache libsepol.print_missing_requirements: webalizer's global requirements were not met: type/attribute httpd_sys_content_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! semodule -r webalizer semodule -r apache libsepol.context_from_record: type httpd_openshift_script_exec_t is not defined libsepol.context_from_record: could not create context structure libsepol.context_from_string: could not create context structure libsepol.sepol_context_to_sid: could not convert unconfined_u:object_r:httpd_openshift_script_exec_t:s0 to sid invalid context unconfined_u:object_r:httpd_openshift_script_exec_t:s0 libsemanage.semanage_install_active: setfiles returned error code 1. semodule: Failed! semodule -R [root@xnet241 ~]# semanage port -d -t http_port_t -p tcp 80 /usr/sbin/semanage: Port tcp/80 is defined in policy, cannot be deleted -- *** E-Mail is NOT a SECURE channel *** James B.

Release 7 1503 includes samba-common.i686 (breaks multilib installs)

Hi, Unfortunately we are getting multilib issues with the latest release of CentOS 7. It seems that samba-common.i686 conflicts with samba-common.x86_64, and therefore Yum multilib support.

tc seems to have no effect on the NIC's
by Boris Epstein 01 Apr '15

01 Apr '15

Hello all, We have installed this network testing environment: https://github.com/facebook/augmented-traffic-control which seems pretty nice overall. It allows you to artificially degrade your network performance by issuing tc commands to directly affect your networking. I have it set up on two CentOS 6 machines - one a Dell server, one a VirtualBox VM. The tc syntax seems OK, it seems to all make sense - only it seems to have no effect whatsoever on the actual network performance. Hence the question: is there a known issue with tc? Am I perhaps missing some kernel modules, or do I perhaps now have some kernel parameters set correctly? Any insight will be helpful. Thanks in advance, Cheers, Boris.
