Hi, I'm running our local school's mail server on CentOS 7, Postfix and Dovecot. We get quite a lot of spam, so I have the following sender restrictions in my /etc/postfix/main.cf: --8<------------------------------------------------------ # Restrictions SMTP smtpd_helo_restrictions = reject_unknown_helo_hostname smtpd_sender_restrictions = reject_unknown_sender_domain,

Hi, My local server is running CentOS 7. The machine has two NICs and is acting as a gateway. For DHCP and DNS, I'm using Dnsmasq. I have a strange little problem with local hostname resolution. Before going into more details, here's my configuration. [root at nestor:~] # ifconfig enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.2 netmask

Hi, I've been working with Squid + SquidGuard for a few years, though only on Slackware. I'm currently transferring my proxy expertise to CentOS 7, and right now I'm having a little problem with that. Squid works perfectly so far as a transparent HTTP + HTTPS cache proxy. The next step is to add SquidGuard, so I installed it and edited the most basic /etc/squid/squidGuard.conf file

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

Hi, My mail server is running on CentOS 7 with Postfix, Dovecot and Spamassassin. I get quite a lot of spam on a few accounts, and Spamassassin does its job fine. Spam mail is identified correctly, and it looks like there are no false positives, e. g. valid mail is never identified as spam. When a message is flagged as spam, the subject line is rewritten to begin with [SPAM]. Then, a filter in

Hi, A couple months ago, I migrated our local school (two servers, 20 desktop clients) from Slackware 14.1 to CentOS 7. The desktop clients are running a customized lightweight desktop based on Xfce: https://blog.microlinux.fr/poste-de-travail-xfce-centos-7/ Home directories are all on the server, and authentication is centralized. Everything works fine so far. With Slackware I had found a

Hi, Procmail, it can move messages around based on many rules. Use something like this in postfix main.cf: mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME And something like this in /etc/procmailrc or $HOME/.procmailrc SPAMDIR=$HOME/Maildir/.Spam/ :0fw | /usr/bin/spamc :0 * ^X-Spam-Status: Yes $SPAMDIR DEFAULT=$HOME/Maildir/ ORGMAIL=$HOME/Maildir/ DROPPRIVS=yes HTH --

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've setup a transparent HTTP+HTTPS proxy on my server running CentOS 7, using Squid.

I'm trying to setup two CentOS7 systems with automatic security updates to run as my kubernetes nodes. I've also centralized all my outgoing mail through my mailgun service, so I've been using the cli tool "mailx", which I have configured with my credentials. Coming from Fedora32 and CentOS7, dnf-automatic had a helpful emission target that was "email_command". By

Is it possible to redirect --stats to STDERR. I have tryed to do this : /---

Hi, I have a strange problem here. I have two servers, one dedicated webserver, and a local backup server. On the webserver I have this : [root at 12569hpv163154:~] # crontab -l 00 22 * * * /usr/local/bin/sauvegarde-pmbccps.sh This launches a backup script every day at 22:00, and it works as expected. Now here's what I have on the local backup server : [root at grossebertha:~] # crontab

Hello, Although I've been using samba for years at my customers office, I recently moved one on a HP E60 server running RedHat 6.2. The samba version is 2.0.6, untouched from the distribution. They use a (weird) accounting software built on the top of FoxPro, requiring a *huge* amount of open files. I accordingly raised the values for files-nr and inode-nr and the stats seem ok. They have

Hi, I just moved my main mail account and web content from a low-cost (low-quality) provider to my own root server running CentOS 7. I transferred the domain name from DNS management to my registrar, configured BIND, Apache, Postfix, Dovecot, NTP, SELinux, etc. Now things are running rather nicely. One thing is puzzling me though. The updated mail server DNS seems to have spread around so far.

Hi, I just spent two rainy days writing and fine-tuning a post-installation script for CentOS 7 and KDE. https://github.com/kikinovak/centos-7-desktop-kde I've just tested it on three different machines here, and it works quite nicely. Feel free to give it a spin and make some suggestions. Cheers, Niki -- Microlinux - Solutions informatiques durables 7, place de l'?glise - 30730

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 successfully managed to use SSL on a local webserver for testing purposes, following the section "Using SSL" in the Chapter "Using Apache" of the "Definitive Guide to CentOS". Now I wonder: how can I use SSL with virtual hosts? I have several virtual hosts defined. Let's say I want to use SSL with this one: <VirtualHost *:80> ServerAdmin info
