I’ve been meeting a few challenges with running an instance of bacula-fd in each of my jails. Most of them are related to networking. Perhaps my deployment strategies are imposing too many restrictions. The challenges arise on the jail hosts which are not behind my firewall at home. Each of those servers is accessible through

I’ve been using Bacula since early 2004. I’ve been using FreeBSD since 1998. Jails are a relatively newcomer. I starting using it later in 2004. But it’s only recently that I’ve started using them intensively. Backups are always a touchy subject. With ezjail, the files you need to backup are greatly reduced. You’re not backing

I use FreeBSD Jails. I use them a lot. I have jails for websites. I have jails for regression testing, mail servers, OpenVPN servers, etc. I like jails for many reasons. One of which is being able to create a new jail which is pretty much identical to another jail, except for a few things.

For future reference, this is the knew server. It runs a few jails, including Bacula regression testing services. The filesytems:
This post has been replaced by a newer one. For future reference, this is the slocum server, which I use for various jails and services:
I use FreeBSD. I’ve used it since 1998. For me, it does good stuff, reliably, and predictably. The community is very supportive and helpful. That goes a long way when choosing your open source operating system. Included within FreeBSD, since FreeBSD 4.0 in March 2000, is a great tool for separating out services and to

Tonight I created a new jail, and later installed sudo into that jail. Then I tried to run sudo: $ sudo make install clean sudo: effective uid is not 0, is sudo installed setuid root? What? It is setuid: $ ls -l `which sudo` -rwsr-xr-x 1 root wheel 117112 Jul 26 17:08 /usr/local/bin/sudo I had

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
