I found a nice tool for managing snapshots and replication of ZFS datasets. I needed something like this for my Proxmox server. Getting ZnapZend to play nice with a fresh Proxmox box is a bit of a pain, so read on to learn how to do it. Continue reading →
The behaviour of link aggregation on switches running the HPE Comware NOS struck me as odd, like everything about Comware does. I wanted to set up two gigabit interfaces as an LACP link to a Proxmox hypervisor and figured the knowledge I gained is worth sharing. Continue reading →
Recently, Cumulus Networks placed a blog post on their website claiming that there is no need for switch stacking in campus networks anymore. Even though they raised some good and valid points, there are other important considerations missing. I tried to leave a comment under the post on the Cumulus website.

These include frames like LLDP and STP. The post provides a lot of good background information about Linux, networking and how to get it done.
Some lab images and topologies are very resource-intensive. You can’t just run any lab you want on any host machine. For this reason, I thought it would be worthwhile to share some experience with running Juniper-based labs on Eve-NG. Continue reading →
