Getting snmpwalk to talk to snmpd on FreeBSD

1 Comment / FreeBSD, Open Source / By /

NOTE: If you are looking to configure net-mgmt/net-snmp for the first time, the latest article is Configuration of net-mgmt/net-snmp on FreeBSD. Contrary to all the examples I found, it’s not easy to get snmpwalk to communicate with snmpd. I am using the net-mgmt/net-snmp port with the default configuration options. It was installed with: pkg install net-mgmt/net-snmp This is the minimal configuration file, which should be placed at /usr/local/etc/snmp/snmpd.conf: rocommunity public When starting snmpd […]

In this post, I’m using bind98-9.8.8 from ports on FreeBSD 9.3, in case that helps you. Today, I was adjusting the pgcon.org domain as part of the move from the old server to the new server. This move would also see the website updated to PGCon 2015 and the use of Ansible for configuring that new server. Reloading named When I restarted named, this error appeared: $ sudo service named reload rndc: neither

For future reference. This server formed the backbone of just about everything I did. It hosted about 13 domains. Sadly, it was i386 and would not do for ZFS.

Cunning plan for upgrading jails

Leave a Comment / ezjail, FreeBSD, Jails, Open Source / By /

After a lengthy Twitter discussion this afternoon, and a post to the forums, I decided to alter my ezjail basejail. The issue: when you update the basejail, /etc/rc.d and /etc/periodic do not get updated. This is by design. I wanted those directories to get updated. So I have changed the basejail. I will outline first, and go into more detail after I have changed all the jails On the jail host: NOTE: I

Are FreeBSD jails being shutdown properly?

1 Comment / FreeBSD, Open Source / By /

This was done on FreeBSD 9.2-RELEASE-p10. After my boss told me about losing qmail logs from a jail some time ago when a server was shutdown, I started looking at some tests to ensure that jails are shutdown properly. I am beginning to suspect they are not. Consider this test. I added this to /usr/local/etc/rc.d/nullmailer in the jail named ‘testing’: echo $(date) $0 $1 >> /var/log/shutdown.log And then did this on the jail

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
