Hi!

Run script at startup
by Alan Holt 20 Aug '14

20 Aug '14

Hello, I just install the newest version of Centos 7 and I am a bit disappointed with new /etc/rc/local file I found that it's not usable anymore. *[root@lab3 ~]# cat /etc/rc.local* " THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES" It is highly advisable to create own systemd services or udev rules to run scripts during boot instead of using this file. Usually I was added my script to /etc/rc.local *[root@lab3 ~]# echo /usr/bin/bash /opt/ssh_tunnel.sh >> /etc/rc.local* And it was working perfect. What I should do in new Centos 7, please help. *--* *Best regards.* *Alex Berber* *+9 72 54 285 952 3* *www.linuxspace.org* <http://www.linuxspace.org/>

Hello, thank you for your quick answer. You are completely right with this: because they die away in case of network errors and reboots my script contain Reverse SSH Tunnel: [root@lab3 system]# cat /opt/ssh_tunnel.sh #!/bin/bash ssh -f -N -R 12345:localhost:22 root(a)158.216.189.170 So as I understood from your explanation, I can do it in two different ways. *First way: * To create systemd-unit with path to existing script: [Unit] > Description=My Service > After=network.service systemd-networkd.service network-online.target > [Service] > Type=oneshot > *ExecStart=/usr/bin/bash /opt/ssh_tunnel.sh* > [Install] > WantedBy=multi-user.target *Second way:* To create systemd-unit with all configuration inside. [Unit] > Description=SSH-Forwarding > After=network.service systemd-networkd.service network-online.target > [Service] > Type=simple > ExecStart= > */usr/bin/ssh -i /home/gateway/.ssh/id_ecdsa gateway@${REMOTE_HOST} -N -C* > *-L${LOCAL_ADDRESS}:${LOCAL_PORT}:127.0.0.1:${REMOTE_PORT}*Restart=always > RestartSec=60 > TimeoutSec=30 > CapabilityBoundingSet=CAP_NET_BIND_SERVICE CAP_DAC_OVERRIDE > [Install] > WantedBy=multi-user.target But in First Way I don't see this records: Restart=always > RestartSec=60 > TimeoutSec=30 So that means that my tunnel will die from time to time. (because network failure or something like that) And i see difference in this record (I will try to learn about it): Type=oneshot > Type=simple So this means that the best practice is to use *Second Way* described by you?

Logitech unifying receiver (pairing)
by Toralf Lund 20 Aug '14

20 Aug '14

Hi, Is anyone here using a Logitech wireless mouse our keyboard or whatever using a "unifying receiver". Any luck with pairing new devices with the unit? I've tried various different programs from the net that's supposed to be able to do this, but they all fail in one way or the other. "pairing_tool" and "ltpair" will exit with a "broken pipe" message, while PyUnify.py from https://github.com/AveryLouie/BlogDocs fails says "usb.core.USBError: Input/output error", and solaar (installed via the EPEL Testing repo) fails in the following manner: Traceback (most recent call last): File "/usr/bin/solaar-cli", line 42, in <module> solaar.cli.main() File "/usr/lib/python2.6/site-packages/solaar/cli.py", line 429, in main args = _parse_arguments() File "/usr/lib/python2.6/site-packages/solaar/cli.py", line 421, in _parse_arguments logging.root.addHandler(logging.NullHandler()) AttributeError: 'module' object has no attribute 'NullHandler' This is on a CentOS 6 x86_64 system with all updates installed. Any other ideas? In case you don't know how these units work, note that they generally work just like that as long as you use the device and receiver from the same box, so as to speak. The problem is linking a device to a different receiver - which is supported, but requires software. - Toralf|||||| This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.

Re: [CentOS] SELinux vs. logwatch and virsh
by Bill Gee 20 Aug '14

20 Aug '14

Hi Dan - "ausearch -m avc -ts recent" produces no output. If I run it as "ausearch -f virsh" then it produces output similar to this. Each day's run of logwatch produces three of these audit log entries. The a1 and a2 values are different for each entry, but everything else is the same. =============== time->Mon Aug 18 03:21:03 2014 type=SYSCALL msg=audit(1408350063.257:7492): arch=c000003e syscall=21 success=no exit=-13 a0=11ee230 a1=4 a2=7fff722837b0 a3=7fff72283640 items=0 ppid=2815 pid=2816 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=981 comm="bash" exe="/usr/bin/bash" subj=system_u:system_r:logwatch_t:s0-s0:c0.c1023 key=(null) type=AVC msg=audit(1408350063.257:7492): avc: denied { read } for pid=2816 comm="bash" name="virsh" dev="dm-0" ino=135911290 scontext=system_u:system_r:logwatch_t:s0-s0:c0.c1023 tcontext=system_u:object_r:virsh_exec_t:s0 tclass=file =============== I thought about using audit2allow as you suggest. The problem is then I don't really know what change is required. What exactly will it do? And is there a guarantee that it will work? Regarding your general question ... It seems to me that logwatch can be used to provide feedback on operational status of almost anything on the system. If you go beyond the typical reading of log files, then that often requires running some script or utility program or something. Anytime that is done, I think this kind of problem will appear. Much of what logwatch does is running files through "cat". That process runs as "bin_t" which must be a general type. I wonder what would happen if I changed virsh to the same type. For what it is worth, I have another computer running CentOS 6.5 and VirtualBox. The VBoxManage program must run as the same user which is running the virtual machines, which frustrates me to no end. I finally figured out a way to work around it by setting up a user cron job under that user. It saves the output to a text file. The logwatch script then comes along and reads that file into its output. It works, but it is not ideal. There are obvious problems with synchronization, plus if a computer is running VMs under multiple user accounts, then multiple user cron jobs are needed.

The "by-id" as well as the "by-path" directories were both there. I tried to create directory and the links in the directory manually, but they were gone after the next reboot. I assume that these /dev/disk/ entries are created by some process at boot time, but I have no clue how this is done nor what is wrong with my system. I checked what blkid -L says, but this seems to be OK. ---8<--- device fs_type label mount point UUID ----------------------------------------------------------------------------------------- /dev/sda1 ext4 /mnt/raid a574f30b-fa43-4e34-8498-1cb29c4c261f /dev/sdb1 ext4 /boot 01746f38-6289-4b03-8011-bfac89ed89bd /dev/sdb2 swap <swap> 903a51b7-393d-4df9-9b58-f06a0a80a748 /dev/sdb3 ext4 / 8ef1f6cb-5dfc-497e-83d0-8d91cbbe4939 ---8<--- Any help? btw., the problem appeared when I installed a 18TB raid array. I had to compile the e2fsprogs from the most recent sources using this recipe http://blog.ronnyegner-consulting.de/2011/08/18/ext4-and-the-16-tb-limit-no… to install a very large ext4 file system on the raid disk. best regards --- Michael Schumacher PAMAS Partikelmess- und Analysesysteme GmbH Dieselstr.10, D-71277 Rutesheim Tel +49-7152-99630 Fax +49-7152-996333 Geschäftsführer: Gerhard Schreck Handelsregister B Stuttgart HRB 252024

Things like this keep showing up in my my logs. Any idea what to look for to (1) figure out why and (2) track it to a particular service? systemd: Failed to mark scope session-19.scope as abandoned : Stale file handle -- -- Steve

You would be amazed as what corporate interests have twisted the courts into doing for them through sponsored legislation (DMCA for example). I agree about the BS part but that does not make it unenforceable BS in some jurisdictions. And then there is always the threat of impoverishment through litigation. A big enough complainant can simply litigate frivolous torts to impose an economic penalty on its victim regardless of the outcome. Those sorts of disclaimers simple provide a pretext. I just delete messages with such things; unread whenever I notice them in time, otherwise ignoring the contents if I do not. -- *** E-Mail is NOT a SECURE channel *** James B.

Hulu requires Flash Player 10.1.53.64
by Michael Hennebry 20 Aug '14

I'm running firefox on Centos 6 and am trying to watch a movie on hulu. Hulu requires Flash Player 10.1.53.64 or higher What to do? My recollection is that dealing with flash has always been a pain and that it recently got worse when Adobe EOLed flash for linux. Is this correct? [hennebry@localhost grease]$ uname -a Linux localhost.localdomain 2.6.32-431.20.3.el6.x86_64 #1 SMP Thu Jun 19 21:14:45 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux [hennebry@localhost grease]$ A pointer to instructions would be good. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "SCSI is NOT magic.
