Today I’m setting up snmpd on a new [to me] host. It’s a Dell R730. Previously, my documentation for this was a bit jumbled. It was written in 2015 and contains a few updates and corrections. It was hard to follow, even for me. This new post is an update of that one. See my […]

I’m retiring knew and moving the services over to r730-03. I recently added 2 12TB drives to the latter host. In this post, I’ll start the migration process by identifying what data needs to move, from where, and to where. In this post: knew r730-03 FreeBSD 13.2-RELEASE-p2 The data There are the zpools in question:

The vnet (network subsystem virtualization infrastructure) on FreeBSD is both a blessing and a curse. For me, it isn’t working well with IPv6. I’ve hit issues with pf (since solved, I’m sure). It’s a useful feature but can be confusing. It helps to have lots of time to think about it and what you’re doing.

FreshPorts make use of a simple python daemon (fp_listen). It has been in use since at least 2006. It was (I think) vermaden who mentioned it (I can’t find the reference) and it triggered an idea. The role of fp_listen is to listen for backend notifications and respond accordingly. One of its primary goals is

NOTE: this problem was fixed by moving all the IP addresses to the bridge. See Changing how I use IP address with FreeBSD’s vnet – so IPv6 works I just restarted my pkg01 jail. Now Nagios can’t see it on IPv6. In fact, none of the jails on this host can now ping pkg01. This

It’s good to do automated backups. When you do that, add monitoring to make sure the backups are occurring successfully. In my case, I backup using Bacula. Each job creates a new .bsr file. I copy these files to another location each day. Then I monitor the dates on those files and they should all

Yesterday, I noticed this message in one of the “daily security run output” emails which FreeBSD host can send out. I’ve used net-mgmt/nrpe3 for several years. It checks remote hosts and runs any number of predetermined commands and returns the results. It’s stable, highly configurable, and just keeps running. I had a look at the

I have jails with both IP4 and IPv6 addresses. Lately, I’ve been noticing this in /var/log/messages: And this in console messages: Looking in the jail, it had IPv6 addresses. What gives?

I like Postfix. I’ve been a fan of it for over 20 years. I deployed it on every host for outgoing email. Lately, I’ve taken to using dma (DragonFly Mail Agent) as my preferred mail handler on jails and hosts which don’t need to deal with incoming mail, only outgoing mail. After first getting serious
