Centos7 Postfixadmin with SELInux
by Robert Moskowitz 22 Feb '17

22 Feb '17

Anyone here running Postfixadmin on Centos7 with SELinux? The config.inc.php script has lots of warning comments about what you will have to do to get functions to work with SELinux, but does not supply any policy rules. I am still configuring, and so far I have only done: chcon -R -t httpd_sys_content_rw_t /usr/share/postfixadmin/templates_c (thanks Daniel) I suspect here are more so it can do things like create directories and files in the mail store (e.g. /home/vmail/). Oh my current server is running without SELinux (shutter) and that is one of the many reasons I want to upgrade. Bob

Problems with my simple write conf files method
by Robert Moskowitz 22 Feb '17

22 Feb '17

I have been creating conf files and similar with the following method that I picked up (I think from psotfix docs): cat <<EOF>>/etc/aliases || exit 1 root: youremail EOF See: http://medon.htt-consult.com/Centos7-armv7.html But with postfixadmin I stumbled onto a problem. The following: cat <<EOF>/usr/share/postfixadmin/config.local.php || exit 1 <?php $CONF['database_type'] = 'mysqli'; $CONF['database_user'] = 'postfix'; $CONF['database_password'] = 'xyz'; $CONF['database_name'] = 'postfix'; $CONF['configured'] = true; ?> EOF produces: cat <<EOF>/usr/share/postfixadmin/config.local.php || exit 1 <?php ['database_type'] = 'mysqli'; ['database_user'] = 'postfix'; ['database_password'] = 'xyz'; ['database_name'] = 'postfix'; ['configured'] = true; ?> That is the '$CONF' gets processed. What can I do to avoid this (and any other 'gotchas') or can someone provide an alternative? thanks

usermod under CentOS
by Beartooth 22 Feb '17

22 Feb '17

My wife's PC, running CentOS 6, suddenly quit connecting to the Net. Autodidact that I am, I fumbled with all the hard- and software I could find or dared try, but did no good. So we lugged it down to our favorite shop. While there, she bought a laptop, and asked them to install CentOS and copy all her files from the PC (including two books she's written and is trying to market). They called to ask whether I wanted to specify a username & password, or just use their default dummies. I chose the dummies -- and realized in the night that I've never changed a username before. I think, repeat think, I could hack it with mv and chown, but I had enough sense to try a few manuals and duckduckgo searches. Those eventually led me to usermod, and I took a look at 'man usermod'. It seems to be fairly powerful -- and therefore dangerous as well as apposite. So I ask here: are there caveats, gotchas, and/or other entities of their ilk that I need be wary of? -- Beartooth Staffwright, Not Quite Clueless Power User Remember I know little (precious little!) of where up is.

Centos7: Intel nuc/Linksys usb-ethernet
by johan.vermeulen7＠telenet.be 21 Feb '17

Hello All, I'm installing some DIY routers, composed of Intel nuc's ,Linksys usb-ethernet adapters and Centos7 On most machines I just plug in the usb device, install Centos7 and everything works. But on this one machine the network interface doesn't work.

Centos 7 with Postfixadmin, what provides php5-mysql
by Robert Moskowitz 21 Feb '17

21 Feb '17

I am building a Centos7 mailserver to replace my Centos6 server. This means moving to Apache 2.4 and MariaDB, so I am finding a number of changes from my notes. I now have MariaDB running with the databases created and Apache running. I try accessing postfixadmin and get: DEBUG INFORMATION: MySQL 4.1 functions not available! (php5-mysqli installed?) database_type = 'mysqli' in config.inc.php, are you using a different database? Please check the documentation and website for more information. ================= mysqli is what the config.inc.php says to use for // mysqli = MySQL 4.1+ or MariaDB I installed httpd mod_ssl php mariadb-server Thanks for any help on this.

SELInux conflict with Postfixadmin
by Robert Moskowitz 21 Feb '17

21 Feb '17

postfixadmin setup.php is claiming: *Error: Smarty template compile directory templates_c is not writable.* *Please make it writable.* *If you are using SELinux or AppArmor, you might need to adjust their setup to allow write access.* This goes away with 'setenforce 0', so it is an SELinux issue. I have tried both: restorecon -Rv /usr/share/postfixadmin and chcon -R -t httpd_sys_content_t /usr/share/postfixadmin and they are not the problem. Googling this message doe snot produce any SELinux advice. Any ideas? thanks

movie player vs. mp3
by Michael Hennebry 21 Feb '17

21 Feb '17

I have movie player installed on centos 6. When I try to play an mp3 file, it complains about the lack of a codec, mpeg-1 something 3. google hasn't helped. What package do I need? Trying to install ffmpeg gets me a no such package message. I've dealt with codec issues before. Mostly what I remember is that before I was done, I wanted to kill something. -- 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

that ever puzzling special chars escaping + rdiff-backup
by lejeczek 21 Feb '17

21 Feb '17

hi everyone a good basher around here? I try in a script: _rdiffBack="rdiff-backup -v5 --tempdir /tmp/ --no-eas --exclude-other-filesystems --exclude-symbolic-links" _rdffiExclude="--exclude '**/~*' --exclude '**.tmp' --exclude-regexp '(.glusterfs|.trashcan|temp)'" _execCom=${!2} _sourceDir=${1} _backupTo=${3} __backMeUp() { for _sourceDir in ${_sourceDirs[@]}; do echo \$ ${_execCom} ${_rdffiExclude} ${_sourceDir}/ ${_backupTo} \> ${_logFile} | ${_copyToLog} ${_execCom} ${_rdffiExclude} ${_sourceDir}/ ${_backupTo} > ${_logFile} 2>&1 done } case ${1} in rdiffThis) declare -a _sourceDirs=( /0-ALL.DATA/rdiffThis ); __backMeUp ${@} ;; esac this is a snippet which may look obscure but obvious is: rdiff-backup some data, just that. And when I run it as a script ~]$ runme.sh rdiffThis _rdiffBack toHere I see: Fatal Error: Fatal Error: The file specification ''**' cannot match any files in the base directory You notice that the script echos what it is meant to execute, which suffice I copy&paste that echo in bash prompt... and it works!? No "Fatal Error" And the problem seems to specifically be a shell pattern for --exclude. Take two --exclude out, having: _rdffiExclude="--exclude-regexp '(.glusterfs|.trashcan|temp)'" and script works when invoked, fine! I've been fiddling around but failed to make rdiff-backup 1.2.8 play along. Must be something trivial, right? b.w. L

Latest CentOS-7 image on cloud.centos.org has incorrect checksum
by Jared Baker 21 Feb '17

21 Feb '17

Good day, I initially posted this issue on CentOS-mirror a week ago but did not receive any response. I'm looking for a resolution to a small issue with the cloud image repository for the latest CentOS-7 image. As far as I understand, the latest release of the CentOS-7 image should always be posted to http://cloud.centos.org/centos/7/images/CentOS-7-x86_ 64-GenericCloud.qcow2 The checksum of this file should match the highest numbered version of the cloud image listed in http://cloud.centos.org/centos/7/images/sha256sum.txt However, the actual checksum for CentOS-7-x86_64-GenericCloud.qcow2 is returning as b56ed1a3a489733d3ff91aca2011f8720c0540b9aa27e46dd0b4f575318dd1fa which matches for CentOS-7-x86_64-GenericCloud-1608.qcow2 but NOT CentOS-7-x86_64-GenericCloud-1612.qcow2. The latest image available should be CentOS-7-x86_64-GenericCloud-1612.qcow2 with a checksum of 559bebb4abb2fdf3bd88c917cc11ef b1975bfe4494e666d133a3148ec4e6225d. To further the confusion, the 'Last modified' image is CentOS-7-x86_64-GenericCloud-1611.qcow2 and not -1612. I picked up on this discrepancy because I have a script that monitors & updates our openstack images when new images become available for various distributions. If someone could please correct these inconsistencies it would be greatly appreciated. Thanks, Jared Baker
