I would suggest looking at the mailer daemon logs on both the sending and receiving systems. It would appear that the sending system is having difficulties at the receiving system end.

Robert, If you never changed fail2ban defaults you probably had email aliases defined somewhere in your configurations. Whatever you had it was incorrect and it's not worth the effort to figure out why it ever worked if at all. The "right" way is to use email addresses in (at least locally) routable domains.

PXE install in a boot on san with LVM environment, fails after reboot
by Damien Gouju 27 Dec '14

27 Dec '14

Hello, I need to automate installation of CentOS 7.0 using PXE and kickstart. My server is diskless, I'm installing CentOS on a 25GB LUN on a FC SAN with 4 paths. This LUN is the only one accessible by the server. Anaconda processes successfully the installation. But on reboot, I get stuck on a prompt after BIOS. I think I have an issue with storage configuration / bootloader configuration... I can install it using the ISO, with basic configuration. The /root/anaconda-ks.cfg looks like the following (I striped some part, I cannot copy past because I have only console access through a secured VPN :-/ ): firstboot --enable ignoredisk --only-use=mpatha,sdc,sdd,sdb,sda bootloader --location=mbr --boot-drive=mpatha autopart --type=lvm clearpart --all --initlabel --drives=mpatha %packages @base @core %end My ks.cfg template is identical (I also cannot attach it unfortunately…). I tried several things like: - put sda as boot-drive for bootloader (according to http://osdir.com/ml/general/2014-09/msg52181.html ), but anaconda fails with error that this drive cannot be found. It asks to choose another disk, mpatha is the only available. - same with dm-0 (as /dev/mapper/mpatha is a symlink to /dev/dm-0) but anaconda also fails - add to bootloader « --append="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap" » I also found some post on the web saying that in the « ignoredisk » mpatha mustn't be used but disk/by-id/scsi-XXXX (chapter 23.3.2 of RHEL 7 installation guide), but I don’t know how to manage that. Is someone ever did that kind of PXE installation, with boot on san & LVM, and help me in the kickstart configuration? Any help would be highly appreciated! Best regards, Damien

CentOS 7 boot network problem
by Greg Lindahl 27 Dec '14

27 Dec '14

I rebooted a new CentOS 7 host and it attempted to start postfix and apache before the network came up. Needless to say both complained that they couldn't bind to the requested IP address and "entered the failed state." Did I miss an option somewhere? The network config is a manual one, and I see from the generated file in /etc/sysconfig/network-scripts that ONBOOT="yes"... -- greg

Emacs problem
by Jason Ricles 25 Dec '14

25 Dec '14

I am currently running the latest kept yum version of emacs on Centos 6.6. The issues I am having is that sometimes when I type input, some of the input randomly disappears and will then reappear when I highlight where the missing input should be. Why might this annoying thing be happening, and is there a way to fix it? Also I have not made any edits to emacs preferences so they are set to the defaults, and never happened in Centos 6.5 but now does in 6.6.

Upgrading glibc on CentOS 7 to fix memory leak
by Casey Jordan 23 Dec '14

23 Dec '14

Hi All, I am in a bit of a conundrum I hope someone could give me some advice. I have a CentOS 7 server which currently runs glibc version 2.17.x. That version contains a memory leak described and fixed here: https://sourceware.org/bugzilla/show_bug.cgi?id=17370 Suffice to say, this memory leak is causing some serious issues and I have read that upgrading glibc without also upgrading the entire kernel is not recommended. I was hoping that this fix was back ported into CentOS 7 somewhere and maybe there is a quick fix I just don't know about? This is a production server so stability is a big concern, I can't be trying out any new experimental stuff ;) Thanks everyone! <https://sourceware.org/bugzilla/show_bug.cgi?id=17370>-- -- Casey Jordan easyDITA a product of Jorsek LLC "CaseyDJordan" on LinkedIn, Twitter & Facebook (585) 348 7399 easydita.com This message is intended only for the use of the Addressee(s) and may contain information that is privileged, confidential, and/or exempt from disclosure under applicable law.

openvpn client and KDE Network Manager - with CentOS7
by CS DBA 22 Dec '14

22 Dec '14

Hi All, I am switching from Fedora20 to CentOS7 since I now run all my Linux development in a VM and I get a more robust feature set (i.e. shared folders with the host that "just work", etc) The only issue I have thus far is VPN connections. Looking at what's installed on my old Fedora install I suspect I need these packages: kde-plasma-nm-vpnc kde-plasma-nm-openvpn NetworkManager-openvpn NetworkManager-vpnc However none of these are available in CentOS7, Note I have the centos extras and the EPEL repos enabled. I suspect that I need rpmfusion but I don't see that rpmfusion has a repo for CentOS7... Anyone have any thoughts? Can I simply install the centos6 rpmfusion repo? Thanks in advance
