Intended use: Gateway to my in-house network, providing DNS (internal only), DHCP, Mail server, and web server, backup storage for some systems As a web server, the load is low, so large USB-connected disk works just fine. As a backup device, I am using ZFS and it works well. As a mail server, it's my personal mail primarily, likely running sendmail or postfix. Mac-mini is an x86_64. For use as a gateway, I use the Ethernet connect as a link to a gigabyte switch and WiFi access point, and use a usb-connected dongle for the ethernet connect to the modem/internet. David

There also various Allwinner A64 boards out there. There are some people in Bulgaria that have an ARM-based (Allwinner A64) "laptop" kit, and sells the parts separately, so one can build a custom "box" with a 64-bit ARM that is not specificly a laptop. Some of the Chinese 64-bit ARM boards have multiple network ports, mini-PCI, built in Ethernet switches -- these are intended as the guts for a router (some can also be used as WiFi access points). And some of these also have SATA ports. I don't know if *CentOS* is supported, but there are Debian, Ubuntu, and Fedora images available for these.> > > > Mac-mini is an x86_64. > > > > For use as a gateway, I use the Ethernet connect as a link to a > > gigabyte switch and WiFi access point, and use a usb-connected dongle > > for the ethernet connect to the modem/internet. > > > > David > > > > _______________________________________________ > > CentOS mailing list > > CentOS at centos.org > > https://lists.centos.org/mailman/listinfo/centos > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos > > >-- Robert Heller -- 978-544-6933 Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller at deepsoft.com -- Webhosting Services

My Synology storage appliance thingie is much > dumber than that and has not missed a beat in years.I'm using CentOS 7 and 8 for internal servers but use OpenWrt on a consumer router to do the fancy traffic balancing with the "cake" traffic control module, something the old kernel in CentOS 7 lacks. I'm running an email server with Dovecot IMAP, Spamassassin, and ClamAV and that's a bit of a load so I suspect a Pi would be underpowered for that.

Well, I can't even get the internal dhcp to work, having to forward all that to my bind/dhcp vm guest. Shame on me, as if I get that working I can then think on putting a vpn between wireless and internal networks which is something I really should be doing.> I'm running an email server with Dovecot IMAP, Spamassassin, and ClamAV and > that's a bit of a load so I suspect a Pi would be underpowered for that. >I really think it depends on the load, and only you have access to the performance info to answer that. There are people running all that in docker containers (I could swear I read about an "official" or "officially blessed" postfix container in the postfix mailing list).

The client-side check for new mail anywhere in the tree is a pretty big hit. I'm using Thunderbird and Mulberry on Win10 at the same time for clients. (Each has its advantages and disadvantages, hence my use of both.)
