mounting the FreshPorts chroot within a jail

In my work on FreshPorts, I’ve learned more than the average non-committer about the FreeBSD ports tree and its oddities. Just about everything learns about a port it gets from ‘make -V’. Even this method can be fraught with difficulty. In an attempt to get the fairest information possible, FreshPorts uses a chroot solution, first proposed by Ryan Steinmetz . Previous posts about this particular solution can be found in the FreshPorts blog.

doveadm cannot work without a tty

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. To access

Accessing every jail from a VPN

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

ezjail-jail: making a full backup of a FreeBSD jail with Bacula

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

Using mbox for mail backup

I’ve taken to the concept of sending a copy of each incoming email to a second server, for backup. This could be achieved by an alias. Store them in mbox format. Use newsyslog to rotate it over time. UPDATE: this strategy is mentioned in Scenic BGP Route | TechSNAP 137 at about 0:47:30. As part of disaster recovery, my Maildir would be restored from backup. The emails which arrived after the backup would

Using nullmailer instead of a full blown mail server

My mail server of choice is Postfix. I’ve been using it since 1992. It is what I install on all my servers. But that is going go change today. I just installed nullmailer on my DHCP server. When your machine just sends outgoing email, just as notices, you don’t need a full blown MTA. Something like nullmailer should suffice. The system I’m working on is a FreeBSD jail running FreeBSD 9.1-RELEASE-p4. I’m about

Using ezjail-admin archive to create a new jail, almost like an existing jail

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
