New post: FreeBSD resource monitoring and accounting.A practical tour of the base-system toolkit for figuring out *what is actually using my server*: top, vmstat, systat, gstat, netstat/sockstat, procstat, pfctl, and per-jail attribution with kern.racct and rctl.No ports, no agents. Just FreeBSD.https://blog.hofstede.it/freebsd-resource-monitoring-accounting-and-troubleshooting/#FreeBSD #BSD #Jails #pf #SysAdmin #DevOps #Unix #BSD #Blog

I use FreeBSD jails more way over a decade now. Today I learned, that I can simply do “jexec $jail_name” without a parameter and get a sh shell in the jail. You don’t actually need to put “sh” at the end of the command 🤯 #freebsd #jails #til

It’s bigger on the inside.Successfully trapped a Bhyve hypervisor inside a VNET Jail on FreeBSD 15.0-RELEASE Host -> Jail (named 'tardis') -> Hypervisor -> Virtual Machine.Complete with working dual-stack IPv4/IPv6 routed via pf on the host. Why? Because I needed to isolate the VMs from the host's network, and I apparently enjoy fighting deep-nested devfs rulesets on a Friday night. #FreeBSD #bhyve #jails #networking #devops #sysadmin

@mrcool Glad it worked
