Hi, I have CentOS 7 running on half a dozen public servers. For some stuff like automatic updates using yum-cron, I have Postfix installed with a relatively basic configuration. This allows me to send important notifications to my mail address info at microlinux.fr. When there's a batch of updates, I get one mail per machine, so I can check quickly if everything went OK without having to

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'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,

How can I pre-sign a server which doesn''t yet have a domain pointing to it? I''m trying to get an EC2 "base image" together which is pre-signed with our master, so I can spin-up as many instances as required. These instances which will all share the same characteristics and files (they''re basically dupes), and will all sit behind a load-balancer, so

We can permanently set hostname using hostnamectl set-hostname. How can we permanently set *domain name* in CentOS 7? I found an article <http://unix.stackexchange.com/questions/239920/how-to-set-the-fully-qualified-hostname-on-centos-7-0> that recommended setting FQDN using hostnamectl. Is that the right way to set hostname and domainname at the same time using *hostnamectl set-hostname*

Hi, I'm running CentOS on all kinds of setups: servers, workstations, desktops and laptops. Up until now, I'm only using NetworkManager on laptops, since it makes sense to use it there. On servers and desktop clients, I usually remove it and configure the network "traditionally" by simply editing /etc/sysconfig/network-scripts/ifcfg-whatever, /etc/resolv.conf, /etc/hosts,

For systems where the local hostname is obtained as a short name without domain, there should be a ssh_config option "DefaultDomain" as in ssh-3.x from ssh.com. For the server, there might be a corresponding option in order to strip the domain name from the remote client name (if it matches the server's DefaultDomain) for use in auth_rhost2, since netgroups usually contain short

Typos in primary DNS/Search domain. ( /etc/resolv.conf ) Typos in /etc/hosts Why. Ping host works ( host file ) ip host.fqdn host Ping host.fqdn

Rowland, thank You for advice. I can manage standard A records, but not sure, what to do with the NS. I can't figure out, how to delete invalid A subrecord of NS record. I'm afraid to experiment much. Please, could You point me to some working example?

Package: logcheck Version: 1.3.7 Severity: normal After installing logcheck on a system it posted an error to the cron mail address hourly. An untrapped script error was posting stderr output to cron. It originated here: # Hostname either fully qualified or not. if [ $FQDN -eq 1 ]; then HOSTNAME="$(hostname --fqdn)" > /dev/null 2>&1 else

Hi, I have a few identical Dell Optiplex 7010 machines that I want to use for our school's computer room. I tried to clone these installations (like I did before on CentOS 5 and various versions of Slackware), but this time I ran into a problem. Here's what I did. 1. Install one computer and zero unused hard disk sectors with dd. 2. Send the image to a local FTP server using G4L

Hi, I'm currently fiddling with Docker Swarm on three sandbox servers running CentOS 7. Unfortunately I couldn't get even the most basic configuration running. After some experimenting and investigating, it turns out there's a problem with FirewallD. Here's what I did first on every single node. # firewall-cmd --permanent --add-service=docker-swarm # firewall-cmd --reload I

Can anyone point out reasons why it might be a bad idea to put this sort of line in your /etc/hosts file, eg, pointing the FQDN at the loopback address? 127.0.0.1 hostname.domain.com hostname localhost localhost.localdomain

Hi, I have several machines running CentOS 6.2 and a strange problem with the hostname of one machine... After every reboot it loses the fqdn hostname. Here is my confguration: ifconfig | grep "inet addr" inet addr:10.0.0.12 Bcast:10.0.0.255 Mask:255.255.255.0 inet addr:127.0.0.1 Mask:255.0.0.0 /etc/sysconfig/network NETWORKING=yes HOSTNAME=x800.mydomain.local
