Centos 7 httpd Permission problems with Postfixadmin
by Robert Moskowitz 17 Feb '17

17 Feb '17

More joy with Centos 7. I am having permission problems with Postfixadmin. I am installing as I have in my notes I did in Centos6 and it is not working. I untar Postfixadmin into /usr/share. The owner is root:root (I even tried root:apache). My postfixadmin.conf file has: alias /mailadmin /usr/share/postfixadmin <Directory "/usr/share/postfixadmin"> AllowOverride AuthConfig </Directory> And I get when I try fqdn/mailadmin You don't have permission to access /mailadmin on this server. When I google this message, I am getting that httpd is not allowing me access. I have even added: allow from all To the above .conf with no change. This is not a SELInux problem as I tried 'setenforce 0' and still get the error. It is as if there is some new security setting in httpd for files not in the www dir (default of /var/www/). Any ideas? thanks

current situation with flash plugins?
by Michael Hennebry 17 Feb '17

17 Feb '17

Is Adobe the only provider of flash plugins? Is it still a gaping security hole? Do the answers depend on the browser? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

Working on installing mailgraph on Centos7-arm - challenges with rpms
by Robert Moskowitz 17 Feb '17

17 Feb '17

One of the joys with getting a little ahead of where epel-armv7hl is, is trying to install packages where not all the dependencies have been debugged. So I am trying to install mailgraph, that i get the noarch rpm from Centos7-x86_64. But it needs RRD which I actually got from the armv7hl building; it just did not make it to the repo. But it wants libpango and libpangocairo. I can't find what provides those. They are not anywhere available to my Fedora 24 notebook and I don't have any 'normal' Centos7 system these days. thanks

GCC 4.9 in CentOS 7 ??
by Alice Wonder 17 Feb '17

17 Feb '17

The following features of the C++11/C++14 standards are not supported by g++: * std::make_unique function (C++14) * digit separators (C++14) * binary literals (C++14) * generic lambdas (C++14) If you are using the GNU C compiler collection (gcc) then you need at least v4.9.x. configure: error: support for required C++11/C++14 features incomplete Is there by chance a compat package for gcc 4.9.x available? I didn't see it in a yum list. I'm trying to build the latest mkvtoolnix and it looks like CentOS 7 gcc is just barely too old :-/

About the flash-plugin
by m.roth＠5-cent.us 17 Feb '17

17 Feb '17

Y'all may remember I posted here weeks ago, that flash-plugin was crashing. There was an update this morning, which I did on my workstation... and it hasn't crashed all day on either of the two radio stations who I listen to via streaming media. mark

USB 2.0 device on a USB 3.0 plug
by Jerry Geis 17 Feb '17

17 Feb '17

When I plug in my device which is USB 2.0 into a 3.0 slot (cause that is all I have) [495042.943074] usb 5-2: new low-speed USB device number 6 using xhci_hcd [495043.100076] usb 5-2: device descriptor read/64, error -71 I receive the above error. Is there a flag or setting that tells the USB to in a 2.0 mode ? Thanks, Jerry

IPv6 broken on Linode
by Alice Wonder 17 Feb '17

17 Feb '17

https://forum.linode.com/viewtopic.php?f=19&t=14570&p=72785 I can not figure out what I need to do. Apparently according to linode support, the VM is trying to grab an IPv6 address with some privacy stuff enabled by default causing it to not grab the IPv6 address that is assigned to me. Nothing I have tried seems to work, and it seems that Linode support are far more familiar with Ubuntu than CentOS. I know CentOS follows Red Hat so I'm not suggesting this is CentOS's fault, but stuff like this really is why I am a much bigger fan of KISS with simple key=value configuration files that don't seem to exist anymore with Linux networking in the Red Hat world. Making things more complex to benefit "Cloud" servers it the worst thing Red Hat ever did. Sorry for the tone, I'm quite frustrated and as an epileptic who doesn't drive, driving down to the SF Bay Area for RHCE classes that won't even be applicable in a few years when they change stuff again isn't really an option. Been using Red Hat since MKLinux DR3 (based on Red Hat 5.1) and been through the training courses before and everything changes. Anyone know what might be going on? And how to get dhclient to grab the "right" IPv6 address, the same one this VM grabbed no problem for well over a year?

Centos7 GeoIP support with BIND
by Robert Moskowitz 16 Feb '17

16 Feb '17

In my new Centos7 BIND DNS server, I am seeing messages in logwatch about GeoIP. Something new for me to learn about, and it seems, configure. Checking to see what packages are available I find: GeoIP.armv7hl 1.5.0-11.el7 @centos-base_rbf GeoIP-data.noarch 1.5.0-11.el7 base GeoIP-devel.armv7hl 1.5.0-11.el7 base GeoIP-update.noarch 1.5.0-11.el7 base and GeoIP.armv7hl is already installed in my image (even before I installed BIND, it seems to be part of a base server?). I am not finding any help for GeoIP on Centos, but for debian/ubuntu they are saying to install geoip-database. Is GeoIP-data the same thing? What about GeoIP-update? Basically, I probably should get started on this, or disable it in my DNS server. Can someone point me to Centos specific help or help me out? thanks

Serious attack vector on pkcheck ignored by Red Hat
by Leonard den Ottolander 16 Feb '17

16 Feb '17

Based on an article that was mentioned on this list https://googleprojectzero.blogspot.nl/2014/08/the-poisoned-nul-byte-2014-ed… I found two attacker controlled memory leaks in the option parsing of pkcheck.c. These memory leaks allow a local attacker the ability to "spray the heap", i.e. initialize large parts of the heap before launching his attack. The original attack uses a setuid binary, because the author "is giving himself a break". However, the fact that the binary in the example is setuid is orthogonal to the fact that heap spraying is a very serious attack vector. Bug reports are filed but closed WONTFIX. I think this is a mistake so I would hope people could weigh in on this. https://bugs.freedesktop.org/show_bug.cgi?id=99626 https://bugzilla.redhat.com/show_bug.cgi?id=1418278 https://bugzilla.redhat.com/show_bug.cgi?id=1418287 Thanks for your interest.
