Centos7 poblems with dnssec-keygen
by Robert Moskowitz 24 Dec '15

24 Dec '15

I am reading: https://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-bind-rndc.html I have bind installed and default config running. I have not applied my customizations yet. The first step I am taking is getting rndc.key created. So reading the guide I am trying to run (while logged in as root, and in /etc): dnssec-keygen -a hmac-md5 -b 256 -n HOST rndc.key The system is just sitting there and doing nothing. I have sshed as another session and do not see any processing being done by dnssec-keygen. Has anyone else done this? Am I doing things in the right order? If it works for others, then there is something wrong with my setup...

CentOS 7.2 installer missing virt-what
by Chris Adams 24 Dec '15

24 Dec '15

In previous CentOS releases, virt-what was included in the install image. This made it easy for me to spin a custom ISO with my package set and a kickstart that would add open-vm-tools or ovirt-guest-agent as appropriate (when installing the respective guest environments). I updated my ISO to 7.2, and virt-what is nowhere to be found. I assume this is copied from RHEL; anybody know any explanation? For now, I'm falling back to matching strings in /sys/class/dmi/id/product_name. Is there some better way to determine what (if any) virtual environment the installer is running under? -- Chris Adams <linux(a)cmadams.net>

Network configuration issue with second public ip on CentOS 6
by Meikel 24 Dec '15

24 Dec '15

Hi folks, I have a server at Soyoustart.com (which is a brand of OVH). I run CentOS 6.7 and have problems with network configuration. I want to add a second public ip (failover ip) to the server and did follow the instructions in the CentOS-section of http://hilfe.ovh.de/AdministrationIpAliasHinzufuegen After executing the required steps I'm not able to reach the host via the second ip from an external host. I tried it with ping and with ssh commands. Here the content of the config files (I anonymized the server ip with xx.xx.xx.xx and the failover ip with yy.yy.yy.yy): $ cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=<name-of-my-host> NOZEROCONF=true GATEWAY=xx.xx.xx.254 $ cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static IPADDR=xx.xx.xx.xx NETMASK=255.255.255.0 ONBOOT=yes GATEWAY=xx.xx.xx.254 $ cat /etc/sysconfig/network-scripts/ifcfg-eth0:0 DEVICE=eth0:0 BOOTPROTO=static IPADDR=yy.yy.yy.yy NETMASK=255.255.255.255 ONBOOT=yes When I restart the network I get a message (two times) saying "RTNETLINK answers: Operation not supported". $ service network restart Schnittstelle eth0 beenden: [ OK ] Loopback-Schnittstelle beenden: [ OK ] Loopback-Schnittstelle hochfahren: [ OK ] Schnittstelle eth0 hochfahren: Determining if ip address xx.xx.xx.xx is already in use for device eth0... RTNETLINK answers: Operation not supported RTNETLINK answers: Operation not supported [ OK ] I can see two interfaces eth0 and eth0:0 $ LANG="" ifconfig eth0 Link encap:Ethernet HWaddr ..:..:..:..:..:.. inet addr:xx.xx.xx.xx Bcast:xx.xx.xx.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:11122 errors:0 dropped:0 overruns:0 frame:0 TX packets:14371 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1362900 (1.2 MiB) TX bytes:3462327 (3.3 MiB) Interrupt:20 Memory:fe500000-fe520000 eth0:0 Link encap:Ethernet HWaddr ..:..:..:..:..:.. inet addr:yy.yy.yy.yy Bcast:yy.yy.yy.yy Mask:255.255.255.255 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:20 Memory:fe500000-fe520000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:3096 errors:0 dropped:0 overruns:0 frame:0 TX packets:3096 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:274948 (268.5 KiB) TX bytes:274948 (268.5 KiB) I'm able to reach the host from another host (outside OVH network) via xx.xx.xx.xx (I use ping and ssh), but not via yy.yy.yy.yy. Just to be sure that there isn't an issue with the firewall I did "service iptables stop" and ran the "ping" and "ssh" commands again with the same result. For ip xx.xx.xx.xx it works, but not for yy.yy.yy.yy. Not sure if this is important, just in case it matters, some additional information: IPv6 is disabled by kernel parameter "ipv6.disable=1" in /etc/grub.conf The two mac addresses I see for eth0 and eth0:0 with the "ifconfig" command are the same. In the OVH/Soyoustart.com GUI I created a virtual mac for the failover ip, I'm not sure if that virtual mac should come into play somewhere? $ uname -a Linux <name-of-my-host> 2.6.32-573.12.1.el6.x86_64 #1 SMP Tue Dec 15 21:19:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux $ LANG="" route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface xx.xx.xx.0 * 255.255.255.0 U 0 0 0 eth0 default vss-gw-6k.fr.eu 0.0.0.0 UG 0 0 0 eth0 Why is yy.yy.yy.yy not reachable from outside? What am I doing wrong or what can I do to narrow down the problem? Regards, Meikel

C7 apache file access
by Robert Moskowitz 24 Dec '15

24 Dec '15

Pulling out what little hair I have here, but stumbled onto a possible problem. I have a server running C6 apache that is set up with personal directories and no problem showing the files. You can see it at: medon.htt-consult.com/~rgm/pogo So I have a C7 apache server I am building. Files I create on the new server are listing fine. Files I have copied (with cp -avr ...) get permission error e.g.: [Wed Dec 23 12:32:49.359323 2015] [negotiation:error] [pid 3208] (13)Permission denied: [client 192.168.160.20:38708] AH00686: cannot read directory for multi: /home/rgm/public_html/biby/ File permissions are the same. So in frustation I try using stat and it shows a different picture: $ stat test/testit File: ‘test/testit’ Size: 6 Blocks: 8 IO Block: 4096 regular file Device: 803h/2051d Inode: 524296 Links: 1 Access: (0664/-rw-rw-r--) Uid: ( 1000/ rgm) Gid: ( 1000/ rgm) Context: unconfined_u:object_r:httpd_user_content_t:s0 Access: 2015-12-23 13:53:04.212993088 -0500 Modify: 2015-12-23 13:53:06.313000584 -0500 Change: 2015-12-23 13:53:06.313000584 -0500 Birth: - $ stat biby/MishnahBerurah-2015-12-18.amr File: ‘biby/MishnahBerurah-2015-12-18.amr’ Size: 2290374 Blocks: 4480 IO Block: 4096 regular file Device: 803h/2051d Inode: 136295 Links: 1 Access: (0664/-rw-rw-r--) Uid: ( 1000/ rgm) Gid: ( 1000/ rgm) Context: system_u:object_r:unlabeled_t:s0 Access: 2015-12-18 06:54:01.000000000 -0500 Modify: 2015-12-18 06:54:01.000000000 -0500 Change: 2015-12-23 13:56:57.273824913 -0500 Birth: - Notice the difference with Context. Wiaht is this httpd_user_content_t? Why on files I create on this system and not those I cp from a USB drive? And is this the problem or something else? thanks

Starting stunnel on boot with CentOS7
by Leroy Tennison 24 Dec '15

24 Dec '15

The stunnel package doesn't come with an init script and systemctl doesn't list it as a service I recognize, I guess I could put it in /etc/rd.d/rc.local or create a script in /etc/rc.d/init.d but thought I'd ask before creating my own solution.

Recovering LVM after crash
by Emmanuel Noobadmin 23 Dec '15

23 Dec '15

I've been trying to cover data from a disk that appeared to had been corrupted after a power outage. The original setup was lvm on md raid 1 which appears to be what is complicating the issue. Apart from /boot, everything was on LVM partitions so I don't have any backup lvm information. Following various guides online, I've recreated duplicated the raid partition with dd onto a new disk, recreated the raid 1 array with missing device, but the pv cannot be found. I've tried to find the lvm uuid using this guide https://www.howtoforge.com/recover_data_from_raid_lvm_partitions but despite dumping twice the data to file, there are no plain text configuration information. The drives are not encrypted so that isn't likely to be the problem. I also used testdisk to try to recover the partitions but it says they cannot be recovered. During analysis, it was able to detect the lvm partitions, extracted output: Linux LVM 1069 146 38 60799 228 29 959567608 Linux 1069 179 7 57740 22 10 910409728 Linux 790 66 45 59780 237 33 947685112 Linux 1069 179 7 57740 22 10 910409728 Linux 29283 103 5 85953 201 8 910409728 Linux 29292 181 10 85963 24 13 910409728 The numbers are start CHS, end CHS and size in sectors. There seems to be way more possible partitions than there should be, possibly results of previous LV resizing. With only such data left, is there any possible way to reconstruct the PV/VG/LV without the uuid and recover data?
