Systemd persistent change to service file
by Michael H 18 Feb '16

18 Feb '16

Hi All, I had my database fall over earlier, Initially I thought it was due to a change in the OS but the postgresql update overwrote my systemd service file. How can I create a file for my postgresql service that will not be overwritten when updates are applied? Am I correct in thinking it will be something like vi /etc/systemd/system/postgresql.service.d/postgresql-limit-stack.conf #with the contents: .include /etc/systemd/system/multi-user.target.wants/postgresql.service [Service] LimitSTACK=17825792 thanks Michael

slightly off-topic, RAID program for on-board SAS 2308-4i ?
by Zube 17 Feb '16

17 Feb '16

Does anyone know what program can be used to query the RAID status from the OS for an on-board LSI SAS 2308-4i? On this page: http://docs.avagotech.com/docs/12351997 there is a curious note on the left that reads: "Integrated MegaRAID support available upon request" After one mostly fruitless round of chatting with LSI/Avago/Broadcom and one completely fruitless round of chatting with HP, I found confirmation under the storage section here: http://www8.hp.com/us/en/mpc/workstations/product-detail.html?oid=5225041#!… It looks like HP didn't "request" MegaRAID support, so MegaCli and StorCli don't see anything and neither does lsiutils (nor hpacucli, tried just for a laugh). Any clues appreciated. Thanks for your time. Cheers, Zube

Openswan <-> VyOS
by John Cenile 17 Feb '16

17 Feb '16

Hello, I'm having a bit of trouble connecting our current CentOS Openswan server with a Vyos server via IPSec. I've posted this on the VyOS forums, but haven't had many helpful responses, so I thought I would ask here. http://forum.vyos.net/showthread.php?tid=26504&pid=29703#pid29703 Basically our Openswan configuration is as follows: conn VYOS keyingtries=0 keylife=20m ikelifetime=2h left=<VYOS IP> right=<OPENSWAN IP> leftsubnets={ 10.1.1.0/24,10.1.2.0/24,10.1.3.0/24,10.1.4.0/24,10.1.5.0/24} rightsubnets={10.2.1.0/24,10.2.2.0/24,10.2.3.0/24,10.2.4.0/24} auto=start authby=secret dpddelay=30 dpdtimeout=120 dpdaction=hold phase2alg=aes256-sha1;modp1536 phase2=esp ike=aes256-sha1;modp1536 Our VyOS configuration is posted in the above forum post, except now I have followed their advice and created 20 tunnels (each subnet to each subnet, if that makes sense). However, when I enabled this, I got the following errors on the Openswan server: Feb 18 01:24:27 OPENSWAN pluto[8010]: "VYOS/3x3" #70: next payload type of ISAKMP Hash Payload has an unknown value: 243 Feb 18 01:24:27 OPENSWAN pluto[8010]: "VYOS/3x3" #70: malformed payload in packet Feb 18 01:24:27 OPENSWAN pluto[8010]: "VYOS/3x3" #70: sending notification PAYLOAD_MALFORMED to <VYOS IP>:500 Feb 18 01:24:27 OPENSWAN pluto[8010]: "VYOS/4x4" #69: next payload type of ISAKMP Hash Payload has an unknown value: 170 Feb 18 01:24:27 OPENSWAN pluto[8010]: "VYOS/4x4" #69: malformed payload in packet Feb 18 01:24:27 OPENSWAN pluto[8010]: "VYOS/5x4" #68: next payload type of ISAKMP Hash Payload has an unknown value: 63 Feb 18 01:24:27 OPENSWAN pluto[8010]: "VYOS/5x4" #68: malformed payload in packet And on our VyOS server we got the following errors: Feb 18 01:17:19 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-20" #381: sending encrypted notification INVALID_ID_INFORMATION to <OPENSWAN IP>:500 Feb 18 01:17:19 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-20" #381: cannot respond to IPsec SA request because no connection is known for 10.1.1.0/24===<VYOS IP>[<VYOS IP>]...<OPENSWAN IP>[<OPENSWAN IP>]=== 10.2.3.0/24 Feb 18 01:17:19 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-20" #381: sending encrypted notification INVALID_ID_INFORMATION to <OPENSWAN IP>:500 Feb 18 01:17:23 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-11" #422: cannot install eroute -- it is in use for "peer-<OPENSWAN IP>-tunnel-3" #403 Feb 18 01:17:23 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-16" #421: cannot install eroute -- it is in use for "peer-<OPENSWAN IP>-tunnel-4" #395 Feb 18 01:17:23 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-20" #420: cannot install eroute -- it is in use for "peer-<OPENSWAN IP>-tunnel-5" #417 Feb 18 01:17:23 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-20" #381: Informational Exchange message must be encrypted Feb 18 01:17:24 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-20" #381: Quick Mode I1 message is unacceptable because it uses a previously used Message ID 0x14702d90 (perhaps this is a duplicated packet) Feb 18 01:17:24 VYOS pluto[20807]: "peer-<OPENSWAN IP>-tunnel-20" #381: sending encrypted notification INVALID_MESSAGE_ID to <OPENSWAN IP>:500 Does anyone have any idea what I might be doing wrong? I've tried doing only 5 tunnels, however then some subnets couldn't reach certain subnets (as I said in the VyOS forum thread), and now I've tried each subnet to each subnet. I can't find much (any) information on it, but does Openswan support VTI interfaces? Would that solve my problem? Thanks in advance.

Nearly Instant Karma
by Chris Olson 17 Feb '16

17 Feb '16

Our smallest network has just three systems permanently attached to a 100/1000 router. There is one additional port available to temporarily plug in a laptop. The largest systems are both Dells, one running Windows 7 and one running CentOS 6.7. The Windows 7 system supports three flavors of Linux as virtual machines. The CentOS system is often used for data file import from USB-attached devices such as cell phones, charging batteries in the USB-attached devices, and for access to external email accounts. The CentOS system was in power save mode when I plugged in a Samsung cell phone for charging and extraction of several photo files. I then moved to the Windows 7 system to do some "paper work" on a web site that is known to require the use of IE for browser access. While on the Windows 7 system I did a quick email check and responded to one of our contacts at a remote site. He was having "difficulty" with file from an external site downloaded on his Windows 7 system. I took the opportunity in my email reply to comment on the great safety and stability of Linux systems. After about two hours I returned to the CentOS 6.7 system to check on the charging status and move the photo files. Yellow lights were showing on both computer and monitor. The system display, and the optical mouse would not return to normal operation as they usually do with a quick push on the front power button. The power button light did turn green and I was able to log in via ssh from a Cygwin shell on the Windows 7 system. It took two reboots executed remotely to bring back full display and mouse functionality. I believe that this was the first time anyone has plugged in a USB device into the CentOS 6.7 system while it is in power save mode.We now have a warning tag hanging over the USB ports on the system. Is there some characteristic of CentOS systems that we should have known about that could have caused this problem? Does Yahoo web mail have an easy way to retract my gloating email?

Alternative IP addresses
by Timothy Murphy 17 Feb '16

17 Feb '16

My CentOS-7 home server has a static IP address. Is there a simple way of organizing the hpptd server so that it is accessible through this address at a remote host, but is accessed at its 192.168 address by a laptop on the WiFi LAN? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

heads up: /boot space on kernel upgrade
by Devin Reade 16 Feb '16

16 Feb '16

I have a CentOS 6 machine that was initially installed as CentOS 6.4 in May of 2013. It's /boot filesystem is 200M which, IIRC, was the default /boot size at the time. The most recent kernel update (2.6.32-573.18.1.el6) fails because of lack of space in /boot. The workaround is edit /etc/yum.conf, reduce installonly_limit from 5 to something lower (I used 3), remove the oldest kernel via 'rpm -e', and then re-apply the update. In this case, it was necessary to use the 'yum update' command line vs the Update Applet due to an incomplete transaction from the failed update. Devin

nfs v3 issues on Centos 7
by Edsall, William (WJ) 16 Feb '16

16 Feb '16

Hello list, So I'm having a strange issue with Centos 7 mounting NFS V3. It starts with autofs. For example, my auto.share file: apps -nfsvers=3 some-server:/mnt/xfs1/& This will mount, but the first mount takes ~30 sec. After this, eventually the mount becomes stale but it still shows as connected in 'mount'. At this point, I can no longer mount NFS shares. Manual mounting example shown below. Any feedback would be appreciated - thank you! /etc/centos-release :::::::::::::: CentOS Linux release 7.1.1503 (Core) mount -t nfs -o vers=3 mdstor:/mnt/xfs1/apps tmpx -v mount.nfs: timeout set for Tue Feb 16 08:33:31 2016 mount.nfs: trying text-based options 'vers=3,addr=143.219.41.19' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 143.219.41.19 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 143.219.41.19 prog 100005 vers 3 prot UDP port 892 mount.nfs: mount(2): Input/output error mount.nfs: mount system call failed Thanks, William

Update on Kernel panic executing gkrellm.
by Lamar Owen 16 Feb '16

16 Feb '16

For what it's worth, back in April of last year I reported that gkrellm had started generating kernel panics with 7.1503's kernel. I can now report that with the latest 7.1511 kernels (327.4.5 being the latest I have installed) gkrellm is once again behaving for me. Just wanted to close the loop and say that whatever had broken has been fixed, for my hardware.

How to install packages from git.centos.org
by Tim 16 Feb '16

16 Feb '16

Hi all, how can I install rpms from git.centos.org? I'd like to install and test the realtime-kernel. It seems to me that https://wiki.centos.org/Sources only means to build srpms. What I ned is an rt-kernel with headers for further compiling. Purpose: I'd like to build a digital audio workstation and for this I'd like to try out CentOS with the following packages first: - kernel-rt - ardour - calf-plugins BTW: Is there an audio SIG? Thanks in advance Tim
