gpg can't decrypt message
by Tim Dunphy 02 Oct '14

02 Oct '14

Hey guys, Having a little gpg issue I was wondering if someone could help me with. A friend of mine sent me an encrypted message. So I searched online and found a a set of keys that correspond with his email address. And imported them. But when I go to decrypt the message, this is what I get: [root@ops:~] #gpg --decrypt roger-message gpg: encrypted with 2048-bit RSA key, ID 9617EA5C, created 2014-10-01 "Roger Sherman <rsherman(a)viddler.com>" *gpg: encrypted with RSA key, ID 9A41C766* *gpg: decryption failed: secret key not available* Here's a listing of keys that shows his key imported: [root@ops:~] #gpg --list-keys /root/.gnupg/pubring.gpg ------------------------ pub 1024D/F186197B 2010-11-30 uid Tim Dunphy <bluethundr(a)gmail.com> sub 2048g/B712B288 2010-11-30 Tim Dunphy <bluethundr(a)gmail.com> *pub 2048R/9E0AD649 2014-10-01 [expires: 2016-10-01]* *uid Roger Sherman <rsherman(a)viddler.com <rsherman(a)viddler.com>>* *sub 2048R/9617EA5C 2014-10-01 [expires: 2016-10-01]* So maybe I just didn't import the right key? Or do you think the message wasn't sent correctly? Who's the dummy here? Me or him? :) Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

[CentOS7] where does cyrus-sasl-sql come from?
by Fran Garcia 02 Oct '14

02 Oct '14

Hi folks, I've just realized that the following package is included in centos7 base, but it's not included in stock EL7. Any ideas why this is? Seems odd they'd forgotten such a useful package in the upstream distribution! # rpm -qi cyrus-sasl-sql Name : cyrus-sasl-sql Version : 2.1.26 Release : 17.el7 Architecture: x86_64 Install Date: Thu 02 Oct 2014 03:47:44 AM CEST Group : System Environment/Libraries Size : 28320 License : BSD with advertising Signature : RSA/SHA256, Fri 04 Jul 2014 03:05:28 AM CEST, Key ID 24c6a8a7f4a80eb5 Source RPM : cyrus-sasl-2.1.26-17.el7.src.rpm Build Date : Tue 10 Jun 2014 06:15:13 AM CEST Build Host : worker1.bsys.centos.org Relocations : (not relocatable) Packager : CentOS BuildSystem <http://bugs.centos.org> Vendor : CentOS URL : http://asg.web.cmu.edu/sasl/sasl-library.html Summary : SQL auxprop support for Cyrus SASL Description : The cyrus-sasl-sql package contains the Cyrus SASL plugin which supports using a RDBMS for storing shared secrets.

Firefox fonts
by Michael Hennebry 01 Oct '14

01 Oct '14

I recently installed some courier fonts. I'm not sure whether Firefox will use them. They are not showing up on Firefoxes font chooser. Do I need to restart Firefox for them to show up? How do I discover what font Firefox actually uses for something? I've found Inspect Element, but I'm pretty sure Firefox is substituting. How do I discover what was substituted? Is there a way to control what Firefox uses for substitution? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "SCSI is NOT magic.

Re: [CentOS] Need to Understand booting process of CENTOS-7

The difficulty being that for much of the Linux infrastructure the official documentation is excessively exalted by being called 'documentation' in the first place. The reason I go to StartPage or DuckDuckGo first is that I have read a lot of the 'documentation' and whatever semantic content much of it contains is too frequently buried under jargon and dependent upon presumed foreknowledge. It does not help that many documentation writers seem to consider the the Laconians' reply to Phillip as being too wordy. The next step no doubt is to quote: "Use the source, Luke. Use the source." And let us not even consider the useful semantic content of 99.99% of all error messages generated by defective software; since there is none. I can hardly justify criticising someone who has limited time and infinite demands thereon turning to the experiences of others as documented on the web and helpfully indexed by Google et al first; before attempting to find the answer in one of the obscure and obfuscated texts that pass for technical documentation in most fields. Computers simply being the one I encounter most frequently and which happens to concern this issue. I use man pages and find most of them helpful. But, frankly, they are of more use as an aide memoire than as a source of instruction. I defy anyone who has never built an RPM package to build one from scratch using nothing more than their source code files and the relevant man pages. If they can get so far as to identify those to begin with. The existence of technical mailing lists, such as this one, is a mute testament to the deficiency of official documentation. No matter how good it may be a technical document will always be incomplete and subject to misunderstanding. One needs context to grasp what another is trying to convey. The experience of others provides that. As to the OP. Well, you have to start some place. Even if the request was awkwardly put and apparently presumptive one must consider that English may not be their native tongue; and that social mores and customs respecting forms of address vary considerably by country. I find it best to give people the benefit of the doubt. If I reply at all I try to provide a pointer to some resource relating to the query that either I have found helpful or has a good reputation for same. -- *** E-Mail is NOT a SECURE channel *** James B.

"power outage"-save / like embedded systems
by Leon Fauster 01 Oct '14

01 Oct '14

I would like to setup a small system based on CentOS6 "power outage"-save as possible. The hardware will be switch off by pulling the plug. To accomplishing this goal, I would mounting some fs parts readonly (e.g. /usr) and thinking about tmpfs for volatile parts (e.g. lock, run under var). Additionally "optimize" some vm.dirty_* kernel- and fs/ext4 parameters. /persistent would be used with jffs2 on a CF card. So far the theory. Does anyone have some experience with such type of systems? Any pointer to pitfalls are welcome. -- Thanks LF

DKIM mails from this mailing lists
by Markus Steinborn 01 Oct '14

01 Oct '14

Hi, I've got some problem receiving mails from this list. Now and then the mails received from this list have an invalid dkim header. Therefore they are rejected by my MTA. This causes me missing same mails and from time to time I get some mail saying: Your membership in the mailing list CentOS has been disabled due to excessive bounces. What is going wromg here? Can the Mailing List Software be optimized to handle DKIM properly? Thanks Markus Steinborn

The CentOS Cloud SIG aims to focus on building, delivering and maintaing the software needed to run cloud infrastructure on premise. This includes all the integration work that is needed with the hypervisors, the storage controllers, the networking stack around it and the user interface components. In many cases, we will rely on and extend the work being done in the Virtualisation SIG, the Storage SIG and other niche specific efforts as they come up in the CentOS Ecosystem. This effort is being bootstrapped by Kushal Das, a long time open source evangalist and cloud engineer; Helping him are Rich Bowen, Haikel Guemar, Garrett Holmstrom, Jaime Melis, Javier Font?n and I'll be working with the group as CentOS Board liason helping them with infra and process requests as they come up. Given the scope of what we are trying to achieve, we are going to need lots of community participation, and we'd like to start by sending a call out to the larger cloud ecosystem to come and join the effort. The initial conversations are all going to take place on the centos-devel mailing list ( http://lists.centos.org/mailman/listinfo/centos-devel ), please come and join the effort.

CentOS 7 turn off power saving by command line
by Jerry Geis 01 Oct '14

01 Oct '14

In CentOS 6 gconftool-2 (command line) is used to enable/disable items. In CentOS 7 I found "settings->power-> blank screen" as something I wish to configure by the command line? How is that accomplished? I brought up gconf-editor and searched for power and blank and found nothing. How can I control this setting from the command line? Thanks Jerry

Layer 2 VPN with OpenSSH on CentOS7 not working!
by Anthony K 01 Oct '14

01 Oct '14

Hi all. I'm trying to bring an Amazon VM into the LAN by following this guide [0]. However, it appears that OpenSSH on either RHEL7 or CentOS7 is broken as it is not creating tap interface but tun interface. I've tried this on both CentOS5 and CentOS6 and they both work as advertised! Downgrading the OS is not an option! CentOS5/6 gives me: ****************** tap1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 500 link/ether 9e:9e:44:9e:49:4c brd ff:ff:ff:ff:ff:ff CentOS7 gives me: **************** tun1: <POINTOPOINT,MULTICAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 500 link/none So, what's broken in 7 - or is it that it requires something different? Cheers, ak. [0]: http://la11111.wordpress.com/2012/09/24/layer-2-vpns-using-ssh/
