    5G Cellular and pfSense

    Any suggestions for cell modems that work well with pfSense? USB or PCI-E; strong preference for 5G on US bands. This is meant as a backup link for a cable modem.

    Intel QAT Cards

    SMB Signing - A Tale

    This is a bit of a longer narrative involving Samba serving files to Windows clients. Once upon a time in the homelab I setup a samba server. Files went in; files went out and everybody was wired up at 1gbps or hanging off wifi. Life was good. In the fullness of time various clients were used...

    Thoughts on Openflow at Home?

    I've recently acquired an ICX7250 for the home lab and have long been intrigued by openflow; while writing ACLs this week I was struck by the duplication and have started looking at faucet.nz.
