You don’t have permission to access /pipermail/bsdcan-announce/ on this server – mailman

Leave a Comment / Mailman, Open Source / By /

I ran into this problem today and spent about 2 hours trying to figure out what went wrong. I composed an email to the Mailman mailing list and never sent it, because I solved the problem. Here is that email: Subject: Cannot view archives via website Hello, I think this is solved, but I’m posting anyway. I *think* the issue is one of permission: Apache, running as user www, cannot access the private […]

If you’re using Postfix for submission and attempts to submit give this messages on the Postix server: Recipient address rejected: Domain not found you’re probably chroot’d. That is, your submssion entry in master.cf looks like this: submission inet n – – – – smtpd When it should look like this: submission inet n – n – – smtpd Penalty against http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL which was my starting point.

pg_dump: aborting because of server version mismatch

Leave a Comment / Backups, Bacula, FreeBSD, Nagios, Open Source, PostgreSQL / By /

Here’s something to be aware of. Update your PostgreSQL client on your Bacula client if it is used for backing up the Catalog. Ngaios just told me: FILE_AGE WARNING: /usr/backups/bacula/MyCatalog.dump is 45125 seconds old and 0 bytes I looked at the backup job from earlier today: 28-Dec 08:15 bacula-dir JobId 195194: shell command: run BeforeJob “/usr/local/bacula/make_catalog_backup.new MyCatalog” 28-Dec 08:15 bacula-dir JobId 195194: BeforeJob: pg_dump: server version: 9.4.0; pg_dump version: 9.3.5 28-Dec 08:15 bacula-dir

zpool upgrade calls for gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot

3 Comments / FreeBSD, Open Source, ZFS / By /

NOTE: when upgrading a zpool, it may be necessary to also upgrade the bootcode for that disk (or disks). Be aware of this before proceeding. I know I have missed this step more at least once. Earlier today I was adding a new pool to the system. After creating the pool, the status showed this: Let’s upgrade that pool now Upgrading the pool Upgrading the pool is easy: Oh… Now what? I wasn’t

Adding two new drives (SSD) to an existing ZFS system

Leave a Comment / Disks, FreeBSD, hardware, Open Source, ZFS / By /

I haven’t tested this yet, but I’ve installed the hardware. The real test will come after a reboot and actual use of the new drives. NOTE: Although this claims to be creating a new ZIL (SLOG) do not believe it. In fact, stop reading right here. There is nothing of use below. What will they be used for? These drives are intended for ZIL (the ZFS Intent Log). This can speed up writes.

This post has been replaced by a newer one. For reference, the previous post on this server is still available. For future reference, this is the slocum server, which I use for various jails and services. This data was gathered adding increasing the RAM from 16GB to 32GB and adding two SSD to the previous configuration. This is my first ZFS system with more than one pool. Merry Christmas The filesystems, well, some

Monitoring backups via Nagios and a shell script

Leave a Comment / Backups, Nagios, Network monitoring, nrpe, Open Source / By /

Backups are useless without restores. I’ve written a few posts about Nagios, my current monitoring tool of choice. Included with Nagios are a number of plugins and you can even write your own plugins. In this post, I’ll show you a shell script I wrote to make sure my backup files turn up where they should, when they should. In my case, these files are database backups, but the idea behind the script
