CentOS 7 : network interface renamed from eth0 to eth1 after reboot
by Nicolas Kovacs 17 Feb '20

17 Feb '20

Hi, I've done my fair share of CentOS 7 installations, but this is the first time I have this kind of weird problem. Here goes. In my office I have a battered Dell Optiplex 320 PC with two NICs that I'm using as a bare metal sandbox server for testing purposes. The CentOS 7 installer sees the connected network card as eth0. But after the first reboot, the interface comes up as eth1. My first reflex was to rename ifcfg-eth0 to ifcfg-eth1 and edit it accordingly. Weirdly enough, on the subsequent reboot the interface comes back as eth0. I took a peek in /etc/udev/rules.d to see if there was any persistent interface definition, but the directory is empty. On a side note, I installed Ubuntu Server 16.04 LTS on that same machine and got the exact same problem. Debian installer sees the main network interface as eth0, but on the first reboot the interface comes back as eth1. Any suggestions ?

NetworkManager on servers
by Nicolas Kovacs 16 Feb '20

16 Feb '20

Hi, I'm currently reading the upstream "Considerations in adopting RHEL 8" document. The chapter about networking states that traditional networking scripts (shipped with the network-scripts package) are considered obsolete. I bluntly admit I don't see the point in this. As far as I'm concerned, I've been a happy user of NetworkManager since the early days (when folks used to call it NotworkManager :oD). It's one of those nifty pieces of software that brought the Linux desktop to the masses - or at least a bit nearer to them - since it allows managing wireless and wired interfaces transparently and easily on a laptop or any computer with a wireless card. On servers though, one of the first post-installation steps I performed was to get rid of Network-Manager and all its components. The servers I'm working on are relatively small-scale and have from one to four network interfaces. Each interface has a corresponding configuration in /etc/sysconfig/network-scripts, and that's it. From there, I rarely - if ever - touch it. In all my setups, NetworkManager is merely a useless layer of abstraction, and I like sticking to the KISS principle and shave off useless layers. Maybe there's a reason to make NetworkManager more or less mandatory from now on, but I don't see it. So I thought I'd rather ask on this list.

CentOS 7, Fail2ban and SELinux
by Nicolas Kovacs 13 Feb '20

13 Feb '20

Hi, I'm running CentOS 7 on an Internet-facing server. SELinux is in permissive mode for debugging. I've removed FirewallD and replaced it with a custom-made Iptables script. I've also installed and configured Fail2ban (fail2ban-server package) to protect the server from brute force attacks. Out of the box, Fail2ban doesn't seem to play well with SELinux. Here's what I get. $ sudo sealert -a /var/log/audit/audit.log 100% done found 5 alerts in /var/log/audit/audit.log ------------------------------------------------------------ SELinux is preventing /usr/bin/python2.7 from read access on the file disable. ***** Plugin catchall (100. confidence) suggests ***** If you believe that python2.7 should be allowed read access on the disable file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'f2b/f.sshd' --raw | audit2allow -M my-f2bfsshd # semodule -i my-f2bfsshd.pp ... As far as I can tell - and please correct me if I'm wrong - if a package doesn't play well with SELinux in the default configuration, this should be considered as a bug. In that case, the appropriate reaction would be to file a bug on the EPEL mailing list, since EPEL provides the fail2ban-server package. Other than that, the solution suggested by sealert seems to work. $ sudo ausearch -c 'f2b/f.sshd' --raw | sudo audit2allow -M my-f2bfsshd ******************** IMPORTANT *********************** To make this policy package active, execute: semodule -i my-f2bfsshd.pp $ sudo ausearch -c 'f2b/f.sshd' --raw | sudo audit2allow -M my-f2bfsshd ******************** IMPORTANT *********************** To make this policy package active, execute: semodule -i my-f2bfsshd.pp $ sudo semodule -i my-f2bfsshd.pp $ echo | sudo tee /var/log/audit/audit.log $ sudo systemctl restart fail2ban $ sudo sealert -a /var/log/audit/audit.log 100% done found 0 alerts in /var/log/audit/audit.log Any suggestions ?

Azure cloud images
by Tinu Weber 11 Feb '20

11 Feb '20

Hi, My company would like to use CentOS images on Azure, but on the Azure Marketplace, there are currently only images provided by third parties (whereas on Amazon AWS, there are official, community-maintained images [1]) The wiki refers to [2], so I guess that Azure was at least considered at some point. Are there any plans to also provide these images on the Azure Marketplace, under a centos.org (or similar) organisation? If there are any ongoing efforts (or help is needed), I would love to hear. Thanks in advance! --Tinu [1] https://aws.amazon.com/marketplace/seller-profile?id=16cb8b03-256e-4dde-8f3… [2] http://cloud.centos.org/centos/7/images/
