We use Linux for many of our internal systems. As such, we're quite familiar with basing an entire business on running Linux and have developed a strong familiarity with a lot of the software which runs on Linux.
- Office and integration software such as Samba, CUPS, LibreOffice/OpenOffice, Thunderbird, and IRC/XMPP clients.
- Server software such as Apache, nginx, Postfix, bind, PowerDNS, Squid, DHCP servers, MySQL, and some PostgreSQL.
- Networking and infrastructure software such as the Linux network stack, iptables, Sanewall/Firehol, proxy ARP, tunnels, OpenVPN, IPSec, keepalived (VRRP), conntrackd, and IPv6.
- File transmission and backup software such as ProFTPD, Bareos/Bacula, rsync, and rsnapshot.
- Desktop environments such as GNOME, KDE, XFCE, IceWM, and awesome.
Considering most of the folks who work here use Linux both at work and at home, we have a lot of experience with different distros. We service the following distros:
- CentOS/RHEL - Used on many of our servers, we have the most experience with this category. We run our own custom internal yum repository and mirror, build our own RPMs, and deal with the quirks of RedHat-style sysconfig/network-scripts networking.
- Debian - Used on some of our servers, workstations, as well as at least one of our cell phones and our ARM devices. An excellent choice for very small installations.
- Ubuntu - Used on some of our servers, runs our office WiFi, and we do workstation administration for one of our customers who uses this.
- Fedora - Also used within VI. Though not as popular with our customers, we are familiar with supporting this, since we have used it when long-term support distros do not have software new enough for what we need.
- Gentoo - The most popular workstation distro among our techs, who use it on an everyday basis.
We regularly host the weekly meetings of the Grand Rapids Linux Users Group. If you're curious as to who we are or what we do, feel free to stop by - the meetings are open to the public and are free. Join the mailing list to receive schedule updates, but we typically meet from 5:00pm-7:00pm every Friday. Often times, since it is at our office, you can get a sneak peak at some of the projects we're working on (such as our 55" touchscreen GIS machine project) and ask us about the hardware we use.
We also regularly present at BarCampGR on topics ranging from Linux distros to 3D printing of server room parts to optimizing Linux to assembly language. Make sure to stop by sometime.
