similar to: Recommended way of handling iptables firewall in CentOS?

Hi, I recently migrated my office's server from Slackware64 14.1 to CentOS 7. Right now I'm in the process of configuring the Squid web proxy. I edited the default /etc/squid/squid.conf, and here's what I have so far: --8<-------------------------------------------------- # /etc/squid/squid.conf # Nom d'h?te du serveur Squid visible_hostname amandine.microlinux.lan #

Hi, I just migrated my office's server from Slackware64 14.1 to CentOS 7. So far everything's running fine, I just have a few minor details to work out. I removed the firewalld package and replaced it by a simple Iptables script: --8<---------------------------------------------------- #!/bin/sh # # firewall-lan.sh IPT=$(which iptables) MOD=$(which modprobe) SYS=$(which sysctl)

Hi, Up until recently, I've been running Wine 1.6.2 on my workstation under Slackware64 14.1. I used it to emulate a handful of legacy apps that ran under Windows XP. They worked perfectly with that setup. After migrating the workstation from Slackware to CentOS 7, I installed the Wine packages, but none of my applications run. I only get an error message about "wrong EXE

Hi, I just installed a fresh CentOS 6.6 desktop. It's a client's machine, it is physically installed on a testbench in my office. Usually, when I perform installations, I start with the base system on the testbench, and once networking is configured, I SSH into it and then do all the fine-tuning remotely. My configuration files, scripts and HOWTOs are all stored in a Github

Hi, I'm currently fiddling with Samba, trying to make it work on CentOS 7. Before that, I ran Samba successfully in a mixed environment with Slackware64 14.1 on the server and Slackware/Windows Seven on the client side. I have three sandbox machines running CentOS 7. One has a minimal install with only the samba and samba-client packages. Just to be on the safe side for fiddling,

Hi, I just configured SquidAnalyzer, a nifty little network statistics tool that I'm using mainly in school networks to monitor network usage. I want to run the '/usr/bin/squid-analyzer' script once a day. I took a peek in /etc/cron.daily, and the package already installed an /etc/cron.daily/0squidanalyzer script. I wanted to know at what time CentOS ran the cron.daily scripts,

Hi Niki, md127 apparently only uses 81.95GB per disk. Maybe one of the partitions has the wrong size. What's the output of lsblk?

Hi, I'm currently experimenting with CentOS 7 in order to get a grasp of everything that's new. After having read the FAQ entry on network interface names, I decided to revert to the tradictional interface naming scheme by adding the relevant kernel options to the bootloader. This went well, I have now two interfaces names 'eth0' and 'eth1' as expected. In my office

Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running

Hi, I just replaced Slackware64 14.1 running on my office's HP Proliant Microserver with a fresh installation of CentOS 7. The server has 4 x 250 GB disks. Every disk is configured like this : * 200 MB /dev/sdX1 for /boot * 4 GB /dev/sdX2 for swap * 248 GB /dev/sdX3 for / There are supposed to be no spare devices. /boot and swap are all supposed to be assembled in RAID level 1 across

Hey every one, Over the past week I have been exploring puppet and had been ignoring an oddity in its output that Luke helped me figure out today. It all started with trying to configure puppet to configure iptables using redhats utility system-config-securitylevel-tui on rhel4. I was able to get it up and running using the following configuration: node default{ firewall {rhel4:

Hi, I'm using the generic system-config-securitylevel-tui program on a remote server to configure my firewall. So far it's been fairly decent, allowing me to open up ports and whatnot. But I want to start blocking a couple of outgoing ports on my machine. I want to lock it down so the only traffic going in our out of my machine is stuff that I specify. Is there a way to do this

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, I'm running CentOS 7 on all my servers, in three different contexts : 1. simple local server 2. public facing server 3. router/gateway/firewall I'm currently in the process of moving my KISS-style network-scripts-style configurations to something more orthodox based on NetworkManager. Scenarios (1) and (2) caused no problems, but (3) is giving me some headache. Let me

Hi, I wonder if there's an easy way to strip down an installation to the bare minimum, e. g. the packages you get when you select "minimum installation". In Slackware, the bone-headed package manager slackpkg has a few nice options, among which 'slackpkg clean-system', which removes all third-party packages in one single operation, or 'slackpkg remove

Hi, I often have to deal with relatively obsolete hardware in schools, public libraries, small town halls, etc. I still have a handful of CentOS 5.x installations around for these, but I wonder what CentOS 6.x desktop specs are, e. g. the minimum requirements (in terms of CPU and RAM) to reasonably run it. Will a battered first-generation P-IV with 512 MB RAM be sufficient? How much RAM does

In following up on the rsh "problem" I was having earlier, I decided to try out the suggestion Felipe sent about using system-config-securitylevel-tui to open up ports 513 and 514, but that doesn't seem to do the job, either. # iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- anywhere anywhere

Hi, I'm running my CentOS 7 desktop in french. LANG is set to fr_FR.UTF-8. In GNOME 3, the menu entries are listed in alphabetical order. Unfortunately, entries beginning with an accented character (like "?diteur de texte") appear at the bottom of the list. I know that in order to correct this, I have to set the LC_COLLATE variable to fr_FR.UTF-8. What would be a sensible place

Hi, I wonder where - and eventually how - GNOME 3 stores its user preferences. I'd like to create a custom user profile, with slightly different settings than the default ones: * don't show home folder on ~/Desktop * don't show Trash * use custom default wallpaper * stretch wallpaper instead of zooming * use different default icon theme * etc. Until now I've done this
