Hi, I'm currently experimenting with OpenVAS, the vulnerability scanner which was forked from Nessus. I'm reading through various HOWTOs and tutorials, and it seems like I'm stuck very early in my fiddling process. All the CentOS-based tutorials I've found mention a third-party Atomic repo, and here's how the installation usually begins. # wget -q -O -

Hi, I'm having a weird problem on a CentOS 6 server. I installed the machine in french, so I have LANG=fr_FR.UTF8 defined. I'd like to define en_US.UTF8, because some output is better readable in english, like chkconfig --list. I replaced fr_FR.UTF8 in /etc/sysconfig/i18n and /boot/grub/grub.conf. Unfortunately, when I reboot the system, I still get this: # echo $LANG fr_FR.UTF-8 Any

Hi, I just upgraded one of my CentOS 7 + GNOME desktops from the CR repo. After the upgrade, it seems like all of the icon themes are broken. Missing icons everywhere. Any idea what's going on here ?

Hi, Our local school has recently acquired an HP PageWide Pro 477 professional printer. According to HP, the printer requires HPLIP 3.16.3 at least. Unfortunately, CentOS is only shipping HPLIP 3.15.9. So I downloaded and installed the hplip/hplipfull package from the HP site. Installing this thing and getting it to work is not exactly a trivial task, as I documented in my blog:

Hi, I'm currently setting up 389 Directory Server on a server running CentOS 7, and I have a weird and somehow showstopping bug. All the spaces are suddenly missing in the admin console. Here's a screenshot so you can get the idea : https://www.microlinux.fr/download/389-admin-console-2020.png So instead of "Standard branch for configuration information", I get

Hi, Can anyone on this list recommend a good style guide for formatting technical documentation (HOWTOs related to CentOS servers) using ASCII text only ? Markdown and/or AsciiDOC are *not* an option, since these documents should be easily readable in a text console.

Hi, I'm looking for recommendations for documentation about the specificities of RHEL/CentOS 7.x. It can be either online or in printed book format, and I'm fluent in german, french and english. I have a good books about 5.x: "RHEL 5 Unleashed" from Sams, "Foundations of CentOS Linux" and "The Definitive Guide to CentOS", both from Apress. Can anyone

Hi, A few days ago I checked the health of my main public server running CentOS 7, a quad-core machine with 16 GB RAM. It had been running non-stop for 65 days, hosting only a handful of services (BIND, NTP, Apache, Postfix, Dovecot) for two domains. I was surprised to see that RAM consumption was relatively high, and apparently, the machine even had to swap at some time. I read up a bit on RAM

Hi, Two weeks ago I migrated all our local school's servers and clients from Slackware 14.1 to CentOS 7. Everything went perfectly, and now I'm busy sanding down some edges. The previous installation sported pdftk and a frontend (can't remember the name) which allowed some basic operations on PDF files such as splitting and concatenation. The school's staff used this application

Hi, I'm using the SquidAnalyzer network analysis tool in combination with Squid. Up until now, I've been running Slackware Linux on my servers. I built a custom package that installs SquidAnalyzer to /var/www/vhosts/squidreport/html. Then I setup an Apache virtual host for SquidAnalyzer's pages. Since I'm migrating my servers from Slackware to CentOS, I'd like to build a

Hi, I'm currently fiddling with Nginx to get acquainted with its various quirks and idiosyncrasies. I have a public CentOS 7 sandbox server, and I've tried various setups. Install the binary from EPEL, install various binaries from SCLo, build from source. I wonder which version is recommended for production use on CentOS 7. Any suggestions? Cheers & happy Christmas holidays,

Hi, I just migrated my workstation running CentOS 7 from KDE to MATE. It looks like I'm having the same problem with the Caja file manager than with Dolphin. Folder contents don't get refreshed automatically, and I have to hit F5. For example, when I download a file (say, a compressed archive) from the Internet, I have to hit F5 to see the file in Caja. And when I extract the archive, I

Hi, I'm currently teaching Linux system administration to a class at the local "chambre de commerce". The course is based mainly on a minimal CentOS 7 installation. Usually my preferred tool for handling manual GPT partitioning is gdisk, which is not installed on a minimal install. I just gave the good old fdisk a spin, which enables GPT partition table creation with the

After some more fiddling, I guess I found a solution to my problem. If we formulate the problem differently, we can say that the clients use the information provided by Dnsmasq, but the

Hi, I've been running Squid successfully on CentOS 7 (and before that on 6 and 5), and it's always been running nicely. I've been using it mostly as a transparent proxy filter in school networks. So far, I've only been able to filter HTTP. Do any of you do transparent HTTPS filtering ? Any suggestions, advice, caveats, do's and don'ts ? Cheers from the snowy South of

Hi, I'm currently installing a dozen CentOS 7 + KDE desktops in our local school. I've already installed a minimal X11 + WindowMaker, and now I want to install KDE on top of that, but the installation fails. There's some broken dependency in the repos. I've narrowed the problem down to the libkexiv2 package. Here's that I get. # yum install libkexiv2 ... --> Running
