centos7: ntpd not started on boot

Hi, I have got problems with the ntp daemon. It is enabled in systemd but is not started on boot. # systemctl status ntpd ● ntpd.service - Network Time Service Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled) Active: inactive (dead) Starting manually works # systemctl start ntpd # systemctl status ntpd ● ntpd.service - Network Time Service Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2016-07-29 10:29:45 CEST; 3s ago Process: 2291 ExecStart=/usr/sbin/ntpd -u ntp:ntp $OPTIONS (code=exited, status=0/SUCCESS) Main PID: 2296 (ntpd) CGroup: /system.slice/ntpd.service └─2296 /usr/sbin/ntpd -u ntp:ntp -g Jul 29 10:29:45 simpil1 ntpd[2296]: Listen normally on 2 lo 127.0.0.1 UDP 123 Jul 29 10:29:45 simpil1 ntpd[2296]: Listen normally on 3 eno1 10.17.66.11 UDP 123 Jul 29 10:29:45 simpil1 ntpd[2296]: Listen normally on 4 lo ::1 UDP 123 Jul 29 10:29:45 simpil1 ntpd[2296]: Listen normally on 5 eno1 fe80::223:24ff:fea7:a264 UDP 123 Jul 29 10:29:45 simpil1 ntpd[2296]: Listening on routing socket on fd #22 for interface updates Jul 29 10:29:45 simpil1 ntpd[2296]: 0.0.0.0 c016 06 restart Jul 29 10:29:45 simpil1 ntpd[2296]: 0.0.0.0 c012 02 freq_set kernel 8.993 PPM Jul 29 10:29:46 simpil1 ntpd[2296]: 0.0.0.0 c61c 0c clock_step -0.180109 s Jul 29 10:29:46 simpil1 ntpd[2296]: 0.0.0.0 c614 04 freq_mode Jul 29 10:29:47 simpil1 ntpd[2296]: 0.0.0.0 c618 08 no_sys_peer I see nothing ntpd related /var/log/messages or journactl during the boot phase.

CentOS 6.7->6.8, ssh-add issue
by m.roth＠5-cent.us 29 Jul '16

29 Jul '16

Folks, I am perplexed. I updated my workstation at work Wed before I left, from 6.7 to 6.8. Then, yesterday, I went to use ssh-add -s libcoolkeypk11.so, which I've done many times before to add the certs from my PIV card... and 100% of the time if fails, letting me SSH_AGENT_FAILURE, cannot add card. Now, using a script called sccr, which uses my public and private key to generate a one-time password (we use the to sudo to root), works with no problem. I used my card to go into the data center this morning, which also reads my card, and had no problem. I've tried eval $(ssh-agent) to start a new instance. Nothing works. Also, pklogin-finder finds the cards, asks for my PIN< and it works. Clues for the poor? mark

SAS drive not showing [SOLVED]
by m.roth＠5-cent.us 29 Jul '16

29 Jul '16

*Finally* found the answer. The case was, if you'll recall, that I had replaced a pair of older, smaller drives with a couple of 8TB SATA drives, and made it RAID1 using the PERC firmware. I was then going to wipe the drive. First, the old ones turned out to be SAS, no SATA. I had tried shoving it into a similar Dell, which I regularly use for shoving SATA drives in, and copying over the network, then putting them (larger drives) in place of the ones they were replacing on other servers. This just wouldn't show as /dev/sdx, the way the SATA did. The solution: a script I found on the 'Net lsi.sh, which depends on you having MegaRaid on the box, shows the four drives, but that one was listed as "unconfigured good". What I needed to do was use MegaCLI64 to first display foreign configurations... and regardless of the other three SATA drives, did show only one, and that was from this SAS drive. I then did a clear foreign configuration. After that, I could use PDMakeJBOD, and all is wonderful. mark

LXC containers - systemd takes a long time to start
by Anthony K 28 Jul '16

28 Jul '16

I've got a CentOS7 server (fully patched) and in it I'm running several LXC containers. I've noticed that whenever I try to launch a service via `systemctl start <service_name>` soon after LXC boot, it will take ~5 minutes before the prompt returns. After that initial delay, starting/stopping/restarting services happens immediately. It might be that this happens because the server is running a large number of (>20) containers. On next reboot, I'll see if it has the same problem when I have just one container. In the meantime, anyone else seen similar behavior?

Thunderbird .desktop file is renamed in version 45.2
by Johnny Hughes 28 Jul '16

28 Jul '16

I was starting my Thunderbird via a script and I thought I would post that the name of the desktop file has changed to help anyone else who was running the desktop file from a script. Old path was: /usr/share/applications/mozilla-thunderbird.desktop New Path is: /usr/share/applications/thunderbird.desktop Thanks, Johnny Hughes

Mounting NFS subdirectories individually or just the parent?
by Frank Thommen 28 Jul '16

28 Jul '16

Hello, does it in any respect (throughput/performance, cpu load, I/O load, resilience, ...) matter, if one mounts subdirectories of an NFS (v3) export into separate directories or if one just mounts the parent directory? I.e. like this: server:/export/base/a -> /mnt/a server:/export/base/b -> /mnt/b server:/export/base/c -> /mnt/c server:/export/base/d -> /mnt/d server:/export/base/e -> /mnt/e or simply like this: server:/export/base -> /mnt I would guess, that it doesn matter at all, but at $work the standard setup on all cluster nodes is, to mount >20 subdirectories from the NFS server individually and the justification is, that is more performant and reliable. Can this be confirmed (or denied)? I couldn't find this method of "NFS performance tuning" mentioned anywhere and from a management perspective the sheer amount of mounted filesystems makes the list confusing and harder to troubleshoot. Any thoughts? Regards frank

CentOS 6 and an SAS drive, hardware
by m.roth＠5-cent.us 27 Jul '16

27 Jul '16

This is... odd. Got a 6.8 box, a Dell R320 lspci tells me 01:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2008 [Falcon] (rev 03) so it *should* accept an SAS drive. I've got a Cheetah that's a few years old, and having pulled it out of another server (in the datecenter), I put it in this box to zero it out for reuse... and the box refuses to see the drive. *Nothing* in dmesg, *nothing* in /var/log/messages, and I tried echo "0" etc to get the SCSI buses to rescan. Anyone have any ideas? mark

How to convert /etc/machine-id into a default-duid for IPv6 static DHCP?
by Patrick Laimbock 27 Jul '16

27 Jul '16

Hi, The use-case is deploying C7 VMs with a pre-set machine-id and default-duid based on the machine-id to facilitate static DHCP with IPv6. The default-duid is found in dhclient6-<value>-eth0.lease and IPv6 DHCP uses default-duid like IPv4 DHCP uses MAC addresses for static DHCP. How does one convert /etc/machine-id to a default-duid (in bash)? 1) /etc/machine-id -> DUID: <read RFC6355 and try to grasp the NetworkManager code at [0] & [1]> Use sha256 hash of machine-id, use first 128 bits, add colons and prepend 00:04: $ MACHINE_ID_SHA256=`cat /etc/machine_id | sha256sum | cut -c1-32` $ TMPID=$(sed -e 's/.\{2\}/&:/g;s/.$//' <<<$MACHINE_ID_SHA256) $ DUID=00:04:`echo $TMPID` Correct? 2) convert $DUID to a default-duid. Example value of default-duid can be found in /var/lib/NetworkManager/dhclient6-<string>-eth0.lease. Will stick the pre-set default-duid in /etc/dhclient6.leases so it gets picked up by NM once the VM is deployed and started. So going from e.g. /etc/machine-id 52d8c0f2a04a462a9c9ac1a906446d85 to duid 00:04:a6:89:54:e8:bf:e2:13:71:82:3d:ea:33:4d:a5:2f:75 to default-duid ??? example: default-duid "\000\004%\011\324\251\274\334\001c\304\366\275\314\220\357\255("; So how does one create the default-duid from the duid? The default-duid seems escaped octal with some chars here and there. The NetworkManager code at [2] that does the duid->default-duid conversion is above my pay grade. Anyone know how do this conversion preferably in bash? TIA, Patrick [0] https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/nm-core… [1] https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/dhcp-ma… [2] https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/dhcp-ma…
