[CentOS] Permanent job in Tokyo, Japan
Hello, I’m working with an employer that is looking to hire someone to fulfil a permanent DevOps-type position at their office in Tokyo. Japanese language is not required; only English. Consequently I had hoped that some members of this mailing list may like to discuss further; off-list. I can be reached using "JamesBTobin (at) Gmail (dot) Com".

For what its worth, Fedora 25 has native support for the Pi 3 now, and the CentOS AltArch SIG is getting pretty close to supporting the Pi3 too. https://wiki.centos.org/SpecialInterestGroup/AltArch/Arm32/RaspberryPi3 -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I have prototyped a similar setup with RasPi. With a 4GB (or higher) SD card, flash storage is not a limiting factor compared routers like TP-Link.

[CentOS] Headless Centos 7 "File and Print Server" install - configure WIFI
Google has done it's usual job and returned lots of results but not led me to a solution. I've just build a Centos 7 "File and Print Server" config, i.e. no screen/keyboard/mouse and no GUI installed. The LAN connection has worked out of the box and I can SSH into the server without issue. However, I cannot find out how to configure the WIFI connection which I need in order to provide Air Print services. I'm using a USB dongle which the kernel has recognised and provides me with a device. I can use that device to scan for available WIFI networks. What I can't do is configure a connection so that the server can connect to the the WIFI network. Can anyone help with a link to suitable instructions?

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 server does not. So in order to make the server use that information, here's how I changed the configuration. First, point /etc/resolv.conf to the server itself: # /etc/resolv.conf nameserver 127.0.0.1 Next, get rid of the 'no-resolv' option in '/etc/dnsmasq.conf': # /etc/dnsmasq.conf domain-needed bogus-priv interface=enp3s1 dhcp-range=192.168.3.100,192.168.3.200,24h local=/sandbox.lan/ domain=sandbox.lan expand-hosts # DNS server=192.168.2.1 # Postes fixes dhcp-host=00:1E:C9:43:A7:BF,bernadette,192.168.3.2 dhcp-host=00:1D:09:15:4A:D8,raymonde,192.168.3.3 After restarting Dnsmasq, everything seems fine now: [root@amandine:~] # host bernadette bernadette has address 192.168.3.2 [root@amandine:~] # host raymonde raymonde has address 192.168.3.3 Cheers, Niki -- Microlinux - Solutions informatiques durables 7, place de l'église - 30730 Montpezat Web : http://www.microlinux.fr Mail : i...@microlinux.fr Tél. : 04 66 63 10 32 ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
