I had a Bacula job fail today: Is bacula-sd running on crey? Yes it is. Can I telnet to port 9103 on crey? Yes, I can: $ telnet 10.5.0.20 9103 Trying 10.5.0.20… Connected to crey.example.org. Escape character is ‘^]’. What about from the nyi-fd server? Can I telnet from there? $ telnet 10.5.0.20 9103 Trying […]

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:

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 first mentioned this idea yesterday. This morning I started implementing it. UPDATE: this strategy is mentioned in Scenic BGP Route | TechSNAP 137 at about 0:47:30. I back up my mail. On a regular and frequent basis. However, I wanted something more. What about the email which comes in between backups? How can I

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

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

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.

Following on from the StartCOM verus Apple issues I mentioned yesterday, I have created a new 4K certificate from StartCOM. Apple has no problem with that certificate. I was in the process of setting up some test servers: Dovecot with a 2048-bit cert Dovecot with a 4096-bit cert Cyrus with a 2048-bit cert Cyrus with
