Does CentOS7 targetcli work to serve out to XEN hosts?
by Rob Townley 09 Jun '15

09 Jun '15

I have been successful at getting one XEN host to initiate a iSCSI connection to a target served by CentOS7, but not a second XEN host. xe sr-create complains the StorageRepository is in use. Is there a configuration change? Another iSCSI target server to use?

Spamassassin: last step
by Timothy Murphy 08 Jun '15

08 Jun '15

I'm running CentOS-7 on my home server, and have setup postfix + dovecot + spamassassin. Everything seems to be working fine, except that while spam is being marked as ***Spam***, it is ending up in ~/Maildir/cur/ . I'd like to divert it to ~/Maildir/.Spam/ (where I can examine it with sa-learn). What is the simplest way to do this? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dubli

Re: [CentOS] Migration to centos 7 and program seg faulting [solved]
by Jerry Geis 08 Jun '15

Thanks for the suggestions. My case ended up being a large local variable (stack data)that was fine before and not fine on CentOS 7. If found it by #ifdef entire main function, my program then ran. I then just started letting in chunks of code to narrow it down. jerry

could not insert 'fuse' error on CentOS 7.1
by Tim Dunphy 08 Jun '15

08 Jun '15

Hey guys, I tried installing the latest fuse on CentOS 7.1. I downloaded the latest version (2.9.4) from sourceforge and did a source install. After rebooting the host, now when I go modprobe fuse, this is what I get! *modprobe: ERROR: could not insert 'fuse': Unknown symbol in module, or unknown parameter (see dmesg)* If I tail dmseg this is all I see, but it doesn't seem relevant: [root@ops:~] #dmesg | tail [ 3.342679] input: PC Speaker as /devices/platform/pcspkr/input/input4 [ 3.351981] piix4_smbus 0000:00:01.3: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr [ 3.502014] ppdev: user-space parallel port driver [ 3.539306] AES CTR mode by8 optimization enabled [ 3.590103] alg: No test for __gcm-aes-aesni (__driver-gcm-aes-aesni) [ 3.635925] alg: No test for crc32 (crc32-pclmul) [ 3.659506] type=1305 audit(1433643281.958:4): audit_pid=472 old=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:auditd_t:s0 res=1 [ 4.084861] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 9.575888] systemd-journald[393]: Received request to flush runtime journal from PID 1 [ 10.702056] Adjusting xen more than 11% (9436999 vs 9311354) Has anyone out there encountered this error with fuse and been able to overcome it?

kvm machine type pc-i440fx-2.1
by Marius Vaitiekunas 08 Jun '15

08 Jun '15

Hi, Could anybody give me some advice, how to define virtual machine type "pc-i440fx-2.1" on latest centos 7.1? I need to live migrate vms from debian based hypervisor and I get an error about unsupported machine types, because on centos there are different naming "pc-i440fx-rhel7.1.0". -- Marius Vaitiekūnas

Open-sourced: OpenCL-based multiphysics simulation software package
by Zeev Pekar 08 Jun '15

08 Jun '15

Dear CentOS community, we would like to announce the recent open-source release of our GPU-enabled multiphysics software - Advanced Simulation Library. http://asl.org.il/ Here are some remarkable benchmarks: http://asl.org.il/benchmarks/multicomponent_flow/ I hope that it will be included in CentOS as a package in some near future (you may join the volunteers from Fedora's SciTech SIG) but till then you might find it useful in its current form. Happy hacking, Zeev ps: Please, "like" us on Facebook, if you find ASL cool: https://www.facebook.com/pages/Avtech-Scientific/828973737156105

Why can't the CentOS get dynamic IP address in WIFI environment?
by Nan Xiao 08 Jun '15

08 Jun '15

Hi CentOS users, I have install CentOS 7 in VirtualBox, and want the guest CentOS using dynamic IP address (The network type is bridged). I find the guest CentOS can works OK when using ethernet cable, but can't get IP address via wireless network. I also posted this issue on stackoverflow (http://superuser.com/questions/922045/how-does-the-guest-os-of-virtualbox-g…). (1) The "ip addr" command outputs: 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 08:00:27:bc:e1:67 brd ff:ff:ff:ff:ff:ff (2) The content of ifcfg-enp0s3: TYPE="Ethernet" BOOTPROTO="dhcp" DEFROUTE="yes" PEERDNS="yes" PEERROUTES="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_PEERDNS="yes" IPV6_PEERROUTES="yes" IPV6_FAILURE_FATAL="no" NAME="enp0s3" UUID="6d221230-f35b-44da-9536-a4e9acfa2bc2" DEVICE="enp0s3" ONBOOT="yes" (3) The network related logs from /var/log/messages: Jun 4 01:52:40 CentOS kernel: drop_monitor: Initializing network drop monitor service Jun 4 01:52:40 CentOS kernel: e1000: Intel(R) PRO/1000 Network Driver - version 7.3.21-k8-NAPI Jun 4 01:52:41 CentOS kernel: e1000 0000:00:03.0 eth0: Intel(R) PRO/1000 Network Connection Jun 4 01:52:41 CentOS systemd-udevd[234]: renamed network interface eth0 to enp0s3 Jun 4 01:52:47 CentOS systemd: Starting Import network configuration from initramfs...

Mail Merge data to a pdf file by overlaying the data on the image
by Gregory P. Ennis 07 Jun '15

07 Jun '15

Everyone, I am looking for a utility that I can use to do a mail merge of data to a pdf image file. The image file does not have any active fields, but will be just an image file. I would like to overlay names addresses etc. We currently do this with a pcl file by just overlaying the data with pcl print positions. However, in order to get the pcl file from an original pdf file we have to use gimp to convert the pdf to pcl file, and we always lose a little resolution. I was wondering if anyone knows of a utility to perform this function without first converting the image to a pcl file. Thanks, -- Greg Ennis

less for CentOS6 with POSIX regex?
by tony＠softins.co.uk 07 Jun '15

07 Jun '15

When I started using CentOS 6 instead of CentOS 5, I discovered that "less" no longer understood \< and \>, which I had been used to using since almost forever. Eventually research revealed that in the Fedora version on which RHEL 6 was based, "less" had been built with the PCRE regex library instead of a POSIX one. So instead of \< and \>, I had to use \b. I found a bugzilla entry about this, which showed that the change had been reverted in a later Fedora release. So I tested CentOS 7, and found "less" has been reverted to using POSIX regex, which I'm glad about. What I want to know is: do any repos have a replacement version of "less" for CentOS 6 that has been built with POSIX regex, so that I don't have to keep switching between the two styles when working on different CentOS versions?
