My gateway is dying. My file server is getting full. Over the past few weeks, I’ve been dealing with aging infrastructure. My development server started acting up and was showing signs of age. This aging desktop box contained 80GB HDD, which means it’s probably 6 or 7 years old. That’s getting on in age. It’s […]

I was trying to recompile sysutils/bacula-client on a FreeBSD 8.4 jail when I encountered some perplexing link errors. It took me a while to figure it out, but with the help of some IRC conversation, we figured it out. I started off by deleting the old (quite old) port: bacula-client-5.0.3 Then I recompiled: cd /usr/ports/sysutils/bacula-client

I recently upgraded a jail server from FreeBSD 8.2 to FreeBSD 8.4. This stopped various jails from starting their own instances of PostgreSQL. The messages in the logs were: Jul 9 14:48:48 building postgres[40785]: [2-1] FATAL: could not create shared memory segment: Function not implemented Jul 9 14:48:48 building postgres[40785]: [2-2] DETAIL: Failed system call

I recently upgraded a jail server from FreeBSD 8.2 to 8.4, and part of that process involved recompiling all of the applications. Along the way, nrpe on one jail stopped working. Nagios was reporting: CHECK_NRPE: Socket timeout after 10 seconds. Trying from the command line gave: $ /usr/local/libexec/nagios/check_nrpe2 -H -H dbclone.example.org -c check_pgsql -t 1

The other day, I disconnected the ethernet cable from my gateway to reroute the cable. Then, perhaps coincidentally, I started seeing these entries: Jul 2 15:19:57 bast kernel: fxp0: discard frame w/o leading ethernet header (len 4294967294 pkt len 4294967294) Jul 2 15:28:01 bast kernel: fxp0: discard frame w/o leading ethernet header (len 4294967294 pkt

I kept seeing these messages: Jun 12 04:09:18 nyi sshd[94523]: Authentication tried for dan with correct key but not from a permitted host (host=dbclone.example.org, ip=10.6.0.9). Jun 12 04:09:18 nyi sshd[94523]: Authentication tried for dan with correct key but not from a permitted host (host=dbclone.example.org, ip=10.6.0.9). I’ve been seeing them for a long time. How long?

I’ve been moving some services around lately. A server is dying and I need to move stuff off it. Today I managed to move Bacula and Nagios onto a new server. After a short bit of struggle, I had just one service check that was failing: check_ping. Here’s the example: $ /usr/local/libexec/nagios/check_ping -H bast.example.org -w

ezjail is my tool of choice for managing jails. I’ve been using it since 2008. Today, I want to do something which ezjail won’t do for me, but will allow me to do. I created a bunch of jails for a Bacula tutorial at BSDCan. Now that I have that server safely home again, I

One of the challenges of providing hands-on demonstrations is giving everyone their own sandbox to play in. I don’t want people to spend time on installing software. I want people to learn about the software in question, specifically Bacula. With this in mind, I’ve been building up a solution based on FreeBSD 9.1, ZFS, and

I’m about to start setting up a ZFS-only box using FreeBSD 8.2. There will be no UFS volumes in this system. Every previous server I have set up has always booted from a gmirror’d UFS system first, then mounted a ZFS array. This time, everything will be on ZFS. I’ve described this server previously when
