Can't install CentOS 7 on SuperMicro X7DB3 with Adaptec AIC-9410 Controller
by homeryan＠sina.com 18 Feb '16

18 Feb '16

I have a server with Super Micro X7DB3 motherboard and Adaptech AIC-9410 controller (http://www.supermicro.com/products/motherboard/Xeon1333/5000P/X7DB3.cfm) The hard disk is single SeaGate SAS disk (300Gb). I'd like to install CentOS 7 on the server, but unfortunately, the CentOS installer can't find any hard disk. I think the problem maybe caused by the disk controller. Can you please tell me how to fix the problem ? Thanks for your help!

Thunderbird can not import S/MIME certificate
by Timo Schoeler 18 Feb '16

18 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, in May 2015 I reported [0] that I can not import my S/MIME certificate. Issuer is GlobalSign. Jan Horak reassigned it to the nss guys ("This seems to be problem in NSS code, reassigning to nss component"), but then the ticket idled and was eventually closed by EOL of Fedora 21 (though I stated it persists with F22). I just reopened the ticket because it still doesn't work. The certificate itself is okay, it works on other platforms. Nobody else using S/MIME?

New glibc for CentOS-6 and CentOS-7 and CVE-2015-7547
by Johnny Hughes 18 Feb '16

18 Feb '16

I normally just let the daily announce post to this list show what is available for updates, but there is a CVE (CVE-2015-7547) that needs a bit more attention which will be on today's announce list of updates. We released a new glibc yesterday for CentOS-6 and CentOS-7 .. it is VERY important that all users update to these versions: This update is rated as Critical by Red Hat, meaning that it is remotely exploitable under some circumstances. Make sure this update works in your environments and update as soon as you can. CentOS-7: https://lists.centos.org/pipermail/centos-announce/2016-February/021672.html https://rhn.redhat.com/errata/RHSA-2016-0176.html CentOS-6: https://lists.centos.org/pipermail/centos-announce/2016-February/021668.html https://rhn.redhat.com/errata/RHSA-2016-0175.html These mitigate CVE-2015-7547: https://access.redhat.com/security/cve/CVE-2015-7547 https://bugzilla.redhat.com/show_bug.cgi?id=1293532 Can't stress how important this update is .. here are a couple stories: http://arstechnica.com/security/2016/02/extremely-severe-bug-leaves-dizzyin… http://www.theregister.co.uk/2016/02/16/glibc_linux_dns_vulernability/ Please note that the ONLY way this is tested to work is with ALL updates from CentOS-6 or CentOS-7 applied along with the glibc updates. So a yum update with base and updates repo enabled is the ONLY tested scenario. Did I say *ONLY* enough? Thanks, Johnny Hughes

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
