OpenVPN clients don’t react well when the server goes down

Leave a Comment / Open Source, OpenVPN / By /

I had a power failure at home tonight. The clients did not react well to the outage. They aren’t at home. They’re out there on the internets.

FreeBSD custom port patches when using poudriere

3 Comments / poudriere / By /

I have a custom patch for Nagios. I use poudriere for building my FreeBSD ports. EDIT: 2023-03-25 I have change the local for my patch files using a hook. See poudriere hooks – I am no longer using /usr/ports/distfiles/local-patches>; instead, I’m using /usr/local/etc/poudriere.d/local-patches. How can I combine the two? I asked that question on the FreeBSD Ports Mailing list. The answer came via IRC, from bsd-x. He introduced me to the concept of

poudriere: options, it’s all about options

Leave a Comment / poudriere / By /

Last night, and again this morning, I thought my inbox was rather light. When I checked Nagios, I found out why. I saw two mail servers: nyi-vpn check_postfix_queue CRITICAL 06-10-2014 12:12:38 0d 12h 51m 40s 4/4 96 mail(s) in queue supernews-vpn check_postfix_queue CRITICAL 06-10-2014 12:11:10 0d 10h 48m 8s 4/4 124 mail(s) in queue It seems we have a problem. Checking the mail logs for one of those servers, I see the reason:

named: error sending response: host unreachable

1 Comment / ezjail, FreeBSD, Jails / By /

Every day for weeks I’ve been seeing these entries in my logs: I could ignore them, but that’s not in my nature. I want to know why this is occurring and fix it. Attempting to find the source, I started a tcpdump on the host: That wasn’t much help. I think I should have logged it to a file. After seeing the log messages again today, and while a little bit of unexpected

Nagios plugin for pkg audit (replacing portaudit) on FreeBSD

2 Comments / FreeBSD, freebsd-update, Jails, Nagios / By /

I’m using FreeBSD 9.2 and Nagios 3.5.1. A few weeks ago I wrote about freebsd-update reminding you to upgrade your affected systems. Since then, freebsd-update has continued to send me false positives about upgrading. Suggestions have been made that I track down Colin Percival at BSDCan 2014, which starts in few days. However, I know at least four people have already arrived, two days before any official event, the first of which is

zfs receive stalled, filesystem 95% full

Leave a Comment / FreeBSD, ZFS / By /

It seems that when I decided to send a filesystem from one server to another, I neglected to establish sufficient space existed. This morning, before I headed to BSDCan, I found that my server was very sluggish and slow to respond. Nagios was flagging all kinds of errors, some of which I’d never seen before. Looking at the system in question, I found the system 95% full: $ zpool list NAME SIZE ALLOC

zfs send on FreeBSD over ssh using mbuffer

2 Comments / FreeBSD, ZFS / By /

I have two ZFS servers which have several TB of space. One of the great ZFS features is the ability to send one filesystem to another filesystem, on the current or another server. I will do this over ssh. One of my servers has a lot of spare space, so I figure I will duplicate my backups there. The source This server contains a Bacula Storage Daemon with access to about 27TB, with
