python script from crontab - problems with proper execution
by Rafał Radecki 27 Oct '16

27 Oct '16

Hi All. I currently have a problem with proper invocation of a python script with cron. non-root $ crontab -l #Ansible: script_repo_scanner 55 11 * * * /usr/bin/python /path/script_repo_scanner.py --bb_user bb_user --bb_pass bb_pass --bd_log_dir /path/logs &> /path/script_repo_scanner.py.log And in /var/log/cron I see that cron executed the script but there is no log output in /path/script_repo_scanner.py.log and the script did not perform his job. So it looks like it has not been run despite entries in /var/log/cron ;) When I execute the command non-root$ /usr/bin/python /path/script_repo_scanner.py --bb_user bb_user --bb_pass bb_pass --bd_log_dir /path/logs &> /path/script_repo_scanner.py.log I get standard output (script logs to stdout) and script does its job. Any clue what I could be missing? BR, Rafal.

rpmbuild question
by m.roth＠5-cent.us 27 Oct '16

27 Oct '16

Hi, folks, Trying to build a package from a gzipped tarball of a python package. I'm trying to build it in /root/rpmbuild. Python has a way to build it, but it creates its own tree, with a clone of the rpmbuild tree under *that*. So, from the specfile, I'm trying to understand, after much googling, what I need to change the Source and BuildRoot to. My latest try for the latter is BuildRoot: %{_builddir}/BUILD/%{name}-%{version}-%{release} For Source0, I want to use the file in SOURCES. Anyone got a better example than what I've been googling? mark

SElinux suggestions needed: migrating backup service
by Leon Fauster 27 Oct '16

27 Oct '16

Hi folks, normally I have not so much to do with SElinux but I expected to get in touch sooner or later :-) I migrated a backup-system from El5 to EL6 and the rsync backup process is complaining about selinux attr's now. client <-> server (fetches via rsync -aHAX) client# sestatus SELinux status: disabled server# sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: permissive Mode from config file: permissive Policy version: 24 Policy from config file: targeted for example, no label for this file on client side: client# ls -laZ /usr/share/zoneinfo/Africa/Bissau -rw-r--r-- root root /usr/share/zoneinfo/Africa/Bissau but on server side: rsync: rsync_xal_clear: lremovexattr("usr/share/zoneinfo/Africa/.Bissau.WaE4wj","security.selinux") failed: Permission denied (13) and server# ls -laZ /BACKUP/usr/share/zoneinfo/Africa/Bissau -rw-r--r--. root root unconfined_u:object_r:locale_t:s0 usr/share/zoneinfo/Africa/Bissau the local (server) destination is mounted like: server# cat /proc/mounts |grep BACKUP /dev/sdc1 /BACKUP ext3 rw,seclabel,nosuid,nodev,noatime,nodiratime,errors=continue,acl,barrier=1,data=ordered 0 0 this partition comes from the former system (EL5 productively used without labeling it and with SElinux disabled). I started to enable SElinux (permissive) on new systems and therefore disabling SElinux like it was done before on the former system is not an option. Any suggestions to avoid the default labeling "unconfined_u:object_r:locale_t:s0"? -- Thanks, LF

Ordering rich rules with firewalld
by Jeff White 26 Oct '16

26 Oct '16

Is there any way to order rich rules in firewalld? If I remove all rules and add them back in firewalld seems to put them in whatever order it feels like. Alternatively, how can I change the default policy of a firewalld zone? At the moment I don't see any way to have a zone accept traffic by default other than adding a rich rule allowing 0.0.0.0/0. -- Jeff White HPC Systems Engineer Information Technology Services - WSU

"Shortcut" for creating a software RAID 60?
by Sorin Srbu 26 Oct '16

26 Oct '16

Hello all, Testing stuff virtually over here before taking it to the physical servers. I found a shortcut for creating a software RAID 10 ("--level=10"), device in CentOS 6. Looking at the below, I don't see anything about a shortcut for RAID 60. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/htm l/Storage_Administration_Guide/s1-raid-levels.html Is RAID 60 an uncommon RAID-configuration, as compared to RAID 10, and this might be why it's missing? Not too cumbersome to first create two RAID 6-arrays, then add them to a RAID 0, but it does take some extra time. Besides, I haven't found any way to fail a member disk, as is possible to do when using RAID level 10. Am I missing something here? -- BW, Sorin ----------------------------------------------------------- # Sorin Srbu, Sysadmin # Uppsala University # Dept of Medicinal Chemistry # Div of Org Pharm Chem # Box 574 # SE-75123 Uppsala # Sweden # # Phone: +46 (0)18-4714482 # Visit: BMC, Husargatan 3, D5:512b # Web: http://www.orgfarm.uu.se ----------------------------------------------------------- # O< ASCII ribbon campaign - Against html E-mail # http://tinyurl.com/ascii-ribbon-campaign # # This message was not sent from an iProduct! # # Please consider the environment before printing this email. # Join the campaign at http://thinkBeforePrinting.org # # MotD follows: Pogo sticks make people jumpy.

Shutdown/Poweroff
by Chris Olson 25 Oct '16

25 Oct '16

Is there a good source of information about how Linux distributions and installers identify and interact with the hardware devices in a system? We are particularly interested in the shutdown process that leads to complete power-off. Thanks.
