If you enable the CR repo on your 6.x machine I believe you'll see these updates, and can install them if you want to check things out. My experience is that there will likely be a few updates from the CR when the production set is released. If you go to: http://mirror.centos.org/centos/6.8/cr/<i386|x86_64>/Packages/ you'll see that there are packages for both 32- and 64-bit, so you should be getting 32-bit updates that will take you up to 6.9.

Mixed bonding and vlan on plain adapter possible?
by Gianluca Cecchi 29 Mar '17

29 Mar '17

Hello, I have a CentOS 7.3 + updates server where my configuration arises from the need to connect via iSCSI to a Dell PS Series storage array and Dell not supporting bonding. So that I need to use 2 nics on the same vlan to connect to iSCSI portal IP and then use multipath. Also, the iSCSI lan is on a dedicated vlan I have only these 2 x 10Gbit adapters and I also need to put other vlans on them through bonding. I plan to use active-backup as bonding mode. My first tests were only with iSCSI in place to verify connection is ok I followed these Dell guidelines, for both multipath and sysctl configs for network adapters: http://en.community.dell.com/techcenter/extras/m/white_papers/20442422 iSCSI vlan is 100 so that the configured devices are p1p1.100 and p1p2.100 and my sysctl config is: net.ipv4.conf.p1p1/100.arp_announce=2 net.ipv4.conf.p1p2/100.arp_announce=2 net.ipv4.conf.p1p1/100.arp_ignore=1 net.ipv4.conf.p1p2/100.arp_ignore=1 # net.ipv4.conf.p1p1/100.rp_filter=2 net.ipv4.conf.p1p2/100.rp_filter=2 So far so good and my lun is viewed this way through multipath [root@ov300 etc]# multipath -l 364817197b5dfd0e5538d959702249b1c dm-3 EQLOGIC ,100E-00 size=1.0T features='0' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=0 status=active |- 7:0:0:0 sde 8:64 active undef running `- 8:0:0:0 sdf 8:80 active undef running I tried a test workload and both paths are used in a balanced way. Now I temporarily stop the iSCSI layer and ifdown the p1p1.100 and p1p2.100 devices and put in place bonding on plain p1p1 and p1p2 interfaces and then vlans over it and bridges (they are for VMs) [root@ov300 ~]# cat /proc/net/bonding/bond1 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: p1p1 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: p1p1 MII Status: up Speed: 10000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: a0:36:9f:2e:4d:80 Slave queue ID: 0 Slave Interface: p1p2 MII Status: up Speed: 10000 Mbps Duplex: full Link Failure Count: 1 Permanent HW addr: a0:36:9f:2e:4d:82 Slave queue ID: 0 [root@ov300 ~]# - ifcfg-bond1.65 DEVICE=bond1.65 VLAN=yes BRIDGE=vlan65 ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no - ifcfg-vlan65 DEVICE=vlan65 TYPE=Bridge DELAY=0 STP=off ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@ov300 network-scripts]# brctl show vlan65 bridge name bridge id STP enabled interfaces vlan65 8000.a0369f2e4d80 no bond1.65 [root@ov300 network-scripts]# The same for vlans 162, while for vlan 187 I only have the bond1.187 without a bridge on top of it At the end I try to re-start the iSCSI components, but it seems now I have iSCSI connection interrupted and not stable.

Nodejs010 Packages giving unresolved dependency error when building the nodejs packages
by Maheshwari, Shagun 29 Mar '17

29 Mar '17

Hi, I am trying to built an ISO with nodejs010 packages but when I run the command "repoclosure -a x86_64 -r <local-repository-name>" to check its further dependencies, it is giving unresolved dependencies error. Example: package: nodejs010-node-gyp-3.2.0-2.el7.centos.noarch from Harman (it's a local repo name) unresolved deps: npm(minimatch) < 0:4 npm(minimatch) >= 0:3 nodejs(engine) >= 0:0.8.0 In ISO we have nodejs010-nodejs-minimatch-3.0.2-1.el7 but it is giving error that npm(minimatch) < 0.4 or npm(minimatch) >= 0:3 and on mirror.centos.org latest version of this package is 3.0.2-1. It was an example, there are many errors like this. So, Please find the attached nodejs-unresolved-dep-erre.log file. I have also attached the list of nodejs's RPMs which I want to include in my ISO. Steps to reproduce this issue: 1. Built all nodejs packages using mock Mock -r centos-7-x86_64 rebuild -define 'scl nodejs010' nodejs010-x.x.x.src.rpm 2. Copy all nodejs rpms in a folder 3. Make a local repository in /etc/yum.repos.d/ folder e.g. 1. cd /etc/yum.repos.d/ 2. mkdir dep.repo 3. copy following lines in dep.repo file: [harman] name=harman baseurl=file:///path of the folder where you have copied your nodejs rpms/ enabled=1 4. Run the following command in that folder where you have copied your rpms: createrepo . 5. Then run repoclosure -a x86_64 -r harman But when I download all nodejs rpms from http://mirror.centos.org/centos-7/7.3.1611/sclo/x86_64/rh/nodejs010/ site and repeat the same steps then it is not giving any unresolved dependency errors. Why it is happening ? or There is any problem with our rpm building process ? Please response and help. Regards, Shagun Maheshwari

mirror for debug_info repo
by jsl6uy js16uy 28 Mar '17

28 Mar '17

Hello all hope all is well. We pull down via rsync from a Centos mirror for general updates/os/etc. I don't see a mirror for debuginfo.centos.org::centos-debuginfo well debuginfo.centos.org. The banner for the site states you should only use this site if you plan to be a public mirror. I have not checked every site on the centos mirror list, checked 10 to 15 in the US, but the only one I found that even had a folder for a debug_info sync stated: "due to size this has been moved to debuginfo.centos.org" I am only syncing debuginfo.centos.org::centos-debuginfo/7/x86_64 and i386. Should I pull from here? Is there a better place? Just trying to do the right thing net/netizen resource usage wise Any help/guidance appreciated thanks all

I hadn't been following webmin for a number of years - we don't use it here. I did find and use it in a job I was in ten years ago - it was the only way I could get LDAP working, as, at the time, the tools that came with the package were *not* ready for prime time.... mark PS: Tried reply, James, but it bounced.

Has that changed? Webmin is as insecure as the administrator cares to make it. Our host systems' Webmin instances listen on a reserved IP address different from the host's DNS entry and that address is only reachable through the host's firewall from specified IP addresses originating on our internal LAN. Further, Webmin is configured to automatically switch to https and use a certificate generated by our corporate private CA. Our gateway firewall blocks all access to the port assigned to Webmin. One has to tunnel in to one of the pre-determined host addresses to obtain remote access. A separate webmin logon is set in the webmin configuration which has no existence on the host system. Webmin can also be configured to restrict the hours and day that asccess is allowed to specific users but we have not bothered with that. The main known weakness is Webmin's dependency on passwords which for all I know is due to my ignorance. If Webmin does support RSA certificate authentication then I would love to be told where it is configured. However,failing that, very long phase phrases mitigate the password issue somewhat. Further, Webmin does support two-factor authentication using Google or Authy. To my knowledge there are no CVEs reported for Webmin since 2015 and I believe that all known problems are resolved in the present release. Which is not to say that there are no exploits left to be uncovered but then again we can hardly claim that about any software. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.

Webmin used to be considered insecure, and people would scream and yell if you suggested using it. Has that changed? mark Ahh, I did not know of this. Well, I'm back to suggesting OP take a little time and get comfortable with firewall-cmd in the terminal. If we want our solid redhat clone then systemd, NetworkManager, and firewalld are soldered into the foreseeable future.

Does fail2ban protect anything other than SSH logins?
by Robert Moskowitz 27 Mar '17

27 Mar '17

I am looking at fail2ban, and all I see is it protecting remote logins to SSH. Does it protect any other access to systems? Well perhaps other than VNC perhaps? thank you

Systemd interface rename does not work
by Matt . 27 Mar '17

27 Mar '17

Hi, I'm moving to Systemd for my network management but I don't see my link name changed when I try to using a .link name. The .network file works right, networkmanager is removed as well to accomplish this. Any idea why the rename is not done ? /etc/systemd/network/0-eth.network [Match] MACAddress=00:1a:4a:a9:0a:17 [Network] Address=172.16.3.141/24 Gateway=172.16.3.254 DNS=172.16.3.1 DNS=172.16.3.2 /etc/systemd/network/0-eth.link [Match] MACAddress=00:1a:4a:a9:0a:17 [Link] Name=eth0

SNMP oddity

Hi all, Not sure if this is on topic or not. I'm trying to query an SNMP value from centos 6 and I get a bad response if I don't specify the MIB to use: 0 digimer@pulsar:~/anvil/striker$ snmpget -v2c -c public -m /home/digimer/Downloads/APC/AP7900/MIB/powernet421.mib 10.255.2.1 .1.3.6.1.2.1.2.2.1.6.2 RFC1213-MIB::ifPhysAddress.2 = Hex-STRING: 00 C0 B7 5F 8A 85 0 digimer@pulsar:~/anvil/striker$ snmpget -v2c -c public 10.255.2.1 .1.3.6.1.2.1.2.2.1.6.2 IF-MIB::ifPhysAddress.2 = STRING: 0:c0:b7:5f:8a:85 Note the second reply is not returning the first character (should be '00:', returning '0:'.

Disabling Firewall/iptables on CentOS 7??
by James Pifer 24 Mar '17

24 Mar '17

I apologize if this has been asked and answered, but I googled and attempted things for several hours today without success. I have a freshly installed CentOS 7 system that I'd like to disable the firewall and all iptables rules. Basically the equivalent of doing iptables -F In a nutshell I've tried the following commands, in many different ways and orders, but when the system restarts it still seems to end up with some form of default rules. It even has a couple rules specifying 192.168.122.0 and I can't figure out where it's coming from. #Disable Firewall systemctl stop firewalld systemctl disable firewalld rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service' rm '/etc/systemd/system/basic.target.wants/firewalld.service' systemctl disable firewalld systemctl stop firewalld iptables --flush iptables --list iptables -L yum install iptables-services service iptables save systemctl enable iptables service iptables save Any help is appreciated. Thanks James

polkit helper timeout and defunct pkla-check-authorization processes on CentOS 7.3
by Edgecombe, Jason 24 Mar '17

24 Mar '17

Hi everyone, We seem to be having issues on multiple CentOS 7.3 machines. The problem seems to revolve around polkitd. At some random time, polkitd seems to stop responding on my systems. Along with this, there might be hundreds of defunct pkla-check-authorization processes. If I reboot, then things are fine for a while. I don't see any activity in the unabridged journal to suggest anything that might be triggering polkitd. The puppet run finished 5 minutes before polkitd lost it's head. polkit version is polkit-0.112-11.el7_3.x86_64 Any help is appreciated. Thanks, Jason Here is some condensed output from the "journalctl -u polkit" command: Mar 09 04:02:14 myhost systemd[1]: Starting Authorization Manager...

kerberized-nfs - any experts out there?
by Matt Garman 23 Mar '17

23 Mar '17

Is anyone on the list using kerberized-nfs on any kind of scale? I've been fighting with this for years. In general, when we have issues with this system, they are random and/or not repeatable. I've had very little luck with community support. I hope I don't offend by saying that! Rather, my belief is that these problems are very niche/esoteric, and so beyond the scope of typical community support. But I'd be delighted to be proven wrong! So this is more of a "meta" question: anyone out there have any general recommendations for how to get support on what I presume are niche problems specific to our environment? How is paid upstream support? Just to give a little insight into our issues: we have an in-house-developed compute job dispatching system. Say a user has 100s of analysis jobs he wants to run, he submits them to a central master process, which in turn dispatches them to a "farm" of >100 compute nodes. All these nodes have two different krb5p NFS mounts, to which the jobs will read and write. So while the users can technically log in directly to the compute nodes, in practice they never do. The logins are only "implicit" when the job dispatching system does a behind-the-scenes ssh to kick off these processes. Just to give some "flavor" to the kinds of issues we're facing, what tends to crop up are one of three things: (1) Random crashes. These are full-on kernel trace dumps followed by an automatic reboot. This was really bad under CentOS 5. A random kernel upgrade magically fixed it. It happens almost never under CentOS 6. But happens fairly frequently under CentOS 7. (We're completely off CentOS 5 now, BTW.) (2) Permission denied issues. I have user Kerberos tickets configured for 70 days. But there is clearly some kind of undocumented kernel caching going on. Looking at the Kerberos server logs, it looks like it "could" be a performance issue, as I see 100s of ticket requests within the same second when someone tries to launch a lot of jobs. Many of these will fail with "permission denied" but if they immediately re-try, it works. Related to this, I have been unable to figure out what creates and deletes the /tmp/krb5cc_uid_random files. (3) Kerberized NFS shares getting "stuck" for one or more users. We have another monitoring app (in-house developed) that, among other things, makes periodic checks of these NFS mounts. It does so by forking and doing a simple "ls" command. This is to ensure that these mounts are alive and well. Sometimes, the "ls" command gets stuck to the point where it can't even be killed via "kill -9". Only a reboot fixes it. But the mount is only stuck for the user running the monitoring app. Or sometimes the monitoring app is fine, but an actual user's processes will get stuck in "D" state (in top, means waiting on IO), but everyone else's jobs (and access to the kerberizes nfs shares) are OK. This is actually blocking us from upgrading to CentOS 7. But my colleagues and I are at a loss how to solve this. So this post is really more of a semi-desperate plea for any kind of advice. What other resources might we consider? Paid support is not out of the question (within reason). Are there any "super specialist" consultants out there who deal in Kerberized NFS? Thanks! Matt

KVM guest fails to boot cleanly

I have a KVM vm running CentOS-6.8 on a host also running CentOS-6.8. This instance is used for occasional development projects which require segregation. Thus it is seldom accessed. At some point in the recent past this guest developed an issue with starting. Specifically these messages were found in the system log files: /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_cm_xnet245.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet241.harte-lyne.ca_00' [32.00 GiB] inherit /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet241.harte-lyne.ca_01' [32.00 GiB] inherit /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet241.harte-lyne.ca_02' [32.00 GiB] inherit /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet242.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet243.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet244.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet245.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_cm_xnet245.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet241.harte-lyne.ca_00' [32.00 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet241.harte-lyne.ca_01' [32.00 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet241.harte-lyne.ca_02' [32.00 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet242.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet243.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet244.harte-lyne.ca_00' [31.25 GiB] inherit /var/log/messages:Mar 20 08:52:10 vhost04 kernel: dracut: inactive '/dev/vg_vhost04/lv_vm_xnet245.harte-lyne.ca_00' [31.25 GiB] inherit It appears that this issue was first encountered on March 10 as our log files go back much further than that and have no earlier record.

I want to connect to a l2tp server from centos.
by Eliezer Croitoru 22 Mar '17

22 Mar '17

I have a server currently connecting to a pptp remote server. This server(lns\lac) has the option for pptp connections and l2tp connections. The l2tp connections are not using ipsec encryption at all. I have seen couple guides\tutorials on the internet: - https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_on_CentOS_-_Red_Hat_Enterpris… - https://wiki.archlinux.org/index.php/L2TP/IPsec_VPN_client_setup But all the guides that I have found are using ipsec with "secret". On ubuntu there is a gui applet that helps setting these kind of connections up but I am working with a CentOS server and not Ubuntu desktop. If someone used l2tp the same way I want to use on CentOS 7 please give me some advice. If you have a guide which might help me I will be more then happy to see this one. Thanks, Eliezer

Centos7 USB wifi recommendation
by Robert Moskowitz 21 Mar '17

21 Mar '17

I am looking for one of those very small USB wifi adapters for the server I am working on. I am tired of dealing with the 4" long TP-LINK I have and for my purposes, one of those little 1cm ones would do. But which work with Linux? When I was last in the store, only the TP-LINK said it was supported on Linux... thanks

I'm poking through Solaris documentation trying to figure out how to make it installable via our PXE server and, as with many things Solaris, I'm hitting walls of completely foreign procedures and setups. Has anyone managed to do this before? I'm trying to set Solaris 11.3 up.

SYSCALL problem in C7
by Fred Smith 20 Mar '17

20 Mar '17

Hi all! I know this isn't a devel list, but thought someone here may have a clue I could use... I have a fairly big application that runs on Centos 7 (and 6 and 5). Sometimes (not often, but too often) when running under the ddd debugger, while sitting stopped at a breakpoint, it will suddenly spew an apparent segfault in, as it says at the top of the source file, "Assembly code template for system call stubs". The specific place always looks like this: T_PSUEDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS) ret_ERRVAL T_PSEUDO_END_ERRVAL (SYSCALL_SYMBOL) the red error marker points to SYSCALL_NAME. I have no idea why its doing this, it never does it when not running in the debugger, as far as I can tell. and why it would croak in the debugger while sitting (apparently) idle at a breakpoint is beyond me. anyone here got a clue? thanks in advance! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven." ------------------------------ Matthew 7:21 (niv) -----------------------------

upgrading Mysql 5.0.95
by Mark Weaver 20 Mar '17

20 Mar '17

Hi All, I'm getting things ready to upgrade my aging installation of MySQL 5.0.95 on my CentOS 5 LAMP server. With the impending EOL date of 3.31 fast approaching my sense of doom and urgency is increasing. I see that the necessary packages are available in @base and @updates - mysql51 and mysql55 respectively but from all the information I've read on the matter so far I'm left with a few questions I don't yet have answers to.' What I've done so far and thankfully was able recover from: 1. installed and enabled to epel repo - ran yum remove mysql - this command wanted to remove a few things I wanted to keep in place like dovecot and a few php53 packages. I didn't want to have to go back and clean up any messes that would create. So, I used the rpm -e --nodeps command to remove the MySQL packages. - because this was a redhat repo it installed the binaries in a total different place AND tossed all my existing data directories. and yes I spit coffee all over my laptop screen and yes, I did have data dir backups and a dump of MySQL data. HOLY CRAP! 2. removed the epel packages - disabled this repo - for ever at least for now... 3. reinstalled the old MySQL 5.0.95 packages - because I was hyper-ventilating - reset roots password - imported all the databases from the dump and checked my web apps - everything working again. - I did have to recreate the mysql.servers table to be able to flush privileges. I understand that mysql51 is available in @base for the sole purpose of upgrading old MySQL and mysql55 is in updates for getting to 5.5, however here is where things get a little fuzzy for me: Steps for Upgrading (as I understand them): 1. Take a dump of all mysql database using mysqldump --add-drop-database --all-databases 2. Stop mysql services 3. make a backup of data directories: /var/lib/mysql (but its not _supposed_ to remove the data directories.) 3. yum remove mysql mysql-server (again, it will include a few things I don't want removed. so, i'll have to use rpm -e --nodeps and list the packages for removal then issue yum clean all.' 4. yum install mysql51 5. start mysql service 6. run command mysql_upgrade... (here's where things start getting fuzzy) Question #1: is this command to be run from the commandline or should I log into mysql as root user and run the command? Question #2: at this point I will have mysql 5.1 installed and running but to get up to 5.5 am I expected to yum remove 5.1 and then yum install 5.5 from @updates and repeat steps 5 and 6 OR simply run the command yum update mysql51* to catch all already installed mysql51 packages to and then run the mysql_update command to bring data up to date with the current mysql install? THank you for your kind attention... -- Mark

Up to date guide/information Sendmail SMTP Auth
by Mark Weaver 19 Mar '17

19 Mar '17

Hello all, I've been googling my brains out since yesterday looking for up-to-date information on this matter, and have found information that is anywhere from 15 to 5 years old. I'd really like some information that much more up to date on the subject. Specifically configuring Sendmail SMTP authentication (_no smart host stuff_). I've got Sendmail 8.14 installed on a CentOS 7.3 server. Also installed: - Cyrus-sasl - Dovecot - Openssl Essentially everything I need except the working knowledge for the process. If someone knows where I might locate this information it would be greatly appreciated. thanks Mark

Centos-6.8 fsck and lvms
by James B. Byrne 18 Mar '17

18 Mar '17

I have a CentOS-6.8 system which has a suspected HHD failure. I have booted it into rescue mode from a CentOS-6.5 minimal install CD in order to run fsck -c on it. The system hosts several vms. I have activated the lvs associated with these vm using pvscan -s ; vgscan ; vgchange -ay. An lvscan shows the lvs as ACTIVE. None are mounted. When I try to run fsck on any of them I see the following error: fsck from util-linux-ng.2.17.2 e2fsck 1.41.12.(17-May-2010) fsck.ext2: No such file or directory while trying to open /dev/vg. . . The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or simething else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> Trying to find alternate super-blocks proves futile: dump2fs /dev/sda2 | grep -i superblock dump2fs 1.41.12 (17-May-2010) dump2fs: Bad magic number in super-block while trying to open /dev/sda2 Couldn't find valid filesystem superblock The file systems on this host were all created as type ext4 and all are lvs with the exception of /boot, which is not an lv and has its own partition on /dev/sda1. I infer that the HDD is gone the way of all flesh; or ferrite as the case may be. But, my ignorance on this is profound so if I am missing some form of recovery step I would appreciate some guidance on how to proceed.

How does one put centos on a laptop? My understanding that laptops no longer come with optical drives. Booting from an install disk would be difficult. >From https://wiki.centos.org/HowTos/Laptops : Preparation tasks Repartition your harddisk Backup your Master Boot Record (MBR) Modifying your bootloader My understanding is that most laptops have at most one harddisk.

PXE vmlinuz kernel doesn't recognize memory in Intel NUC?
by Locane 17 Mar '17

17 Mar '17

Hello all! I'm hoping someone can help. I'm having 2 issues; first: When trying to load a CentOS LiveCD via PXE on an Intel NUC (NUC6CAY), I get: "Not enough memory to load specified image". The image is 1.1 gigs, and there is 16 gigs of memory in the NUC. To combat this, I found this forum post <https://www.centos.org/forums/viewtopic.php?t=1398> which suggested using the "mem=" kernel parameter to manually set it. The next problem I get is one of two things: On a normal working system, I get the dots loading in PXE, then it freezes on "ready." forever On the NUC, I get a sqaushfs crash saying that the image is unusable. My questions are: Has anyone successfully used the "mem=" parameter in a PXE environment? I wasn't even aware that drivers were necessary for a kernel image to read RAM; I'd thought this was something that was just inherent. Does the CentOS PXE kernel need to be updated?

OT: hardware: blackmagic video capture cards
by m.roth＠5-cent.us 16 Mar '17

16 Mar '17

Hi, folks, I'm still trying to find a video capture card that won't crash Dell servers, and ran across a Blackmagic BDLKDUO2 DeckLink Duo 2. It claims to support Linux. I'm also seeing, in the few non-Blabkmagic or sales pages I can find, that they like "binary blobs". I also haven't been able to find anything about o/s or library requirements. Has anyone run across these cards, or know anything at all about them? All we're doing with them is running a few video cameras in for surveillance of our secure rooms, no audio, nothing fancy, with the motion package reading the input. mark

kernel 2.6.32-642.15.1.el6.x86_6
by m.roth＠5-cent.us 15 Mar '17

15 Mar '17

Folks, There's some kind of bug here, esp. with this kernel. We've got a cron yum update, and it fails, repeatably, un multiple machines. We reboot to the previous kernel, it comes up, we do a reinstall of the kernel modules, and everything's fine. I was thinking it was with yum, but the admin I work with says it happened today on some with no exlude=kernel\* in yum.conf. My manager's thinking that the initramfs isn't being rebuilt. Have other folks seen this? Not sure if the other admin's tested it on one of our upstream boxen. mark

How do I confirm importing repo key without user intervention?
by Yuri Kanivetsky 15 Mar '17

15 Mar '17

Hi, Sorry for asking it again. I just thought I asked the question the wrong way. Too much unnecessary details. And therefore, got no replies. I'm configuring a server from, say, a script (automatically). I need it to be done without user saying, "Yes, it's okay to import the key." I was told to run the following command: yum makecache -y --disablerepo=* --enablerepo=passenger Can you confirm if this is okay? Any better ways? Thanks in advance. Regards, Yuri
