I got this message today: $ doveadm pw -s SHA512-CRYPT Enter new password: doveadm(dan): Fatal: open(/dev/tty) failed: No such file or directory It seems if you have no tty, you can’t create a password. Surely there is a better way to do this? # w 7:21PM up 19 days, 4 mins, 0 users, load averages: 0.48, 0.77, 0.67 USER TTY FROM LOGIN@ IDLE WHAT # That’s on a FreeBSD 8.4-RELEASE-p3 jail.

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 a VPN, but the individual jails on those servers are not. The backup of the jail host is

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 up the base OS, just the local files. I’ve created a fileset which seems to do the right

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. In this case, I wanted to create a new jail to do regression testing for Bacula, the best

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This post has been replaced by a newer one.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 provide a virtualization strategy: jails. Some will argue that jails are not virtualization. I contend that it’s a

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 no idea. wxs had the answer: mount points. Here is the problem, as revealed by this command in

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 was shmget(key=5432001, size=12099584, 03600).
