It’s little things like this which improve the copying of backups to tape. Speed. Each of those Volumes are 5GB in size. The tape drive takes about about 2-4 minutes per 5GB to write it to tape. Between the end of IncrAuto-4150 and the end of IncrAuto-1455, the tape drive wrote 20GB in about 9 minutes. That’s roughly 2GB/minute or about 37MB/s.
I am fortunate to receive donations. In the early days, it was a 386 desktop. Later, it was SCSI drives. Recently, it’s been tape libraries. A Bacula user in Europe donated an Overland DLT-8000 tape library in 2012 and paid for shipping to me. At BSDCan 2013, I was fortunate to pick up an Compaq StorageWorks MSL5026 SDLT tape library and it has sat unused. It’s dead Jim A few weeks back, the

With this new server, I am taking a new approach. Each jail will have at least three IP addresses: The public IP4 address, used by internet facing services (e.g. http or https) The public IPv6 address, similar to the above A VPN address, used for system administration and private services (e.g. nrpe) In this article, I will assume you are familiar with ezjail, FreeBSD jails, basic networking, OpenVPN, and ZFS. That is, this

Over the past few weeks, I worked with two different configuration tools: Salt and Ansible. I started working with Salt. I quickly created a setup for a Salt server and for a Salt minion. The modules I saw looked great. However, I had consistently had trouble converting from the documentation to a practical usage. The examples provided always seemed to be CLI. Taking that and converting it to a SLS file caused me

Tonight I asked a question in the OpenVPN IRC channel on FreeNode. me: I’m getting ready to set up a new server, running an OpenVPN client. It will be running several virtual machines (FreeBSD Jails). Each VM will have both a public IP address and a non-routable IP address. I’m hoping to access all those VMs from within the VPN. Am I making sense with my objective here? reply: “clientlan” is (#1) for

My laptop’s hostname is dent. I want my DNS records to point to that laptop whether I’m connected to my LAN directly (via WIFI or ethernet cable) or via OpenVPN (my VPN of choice). SIDE NOTE: You will see references to nsupdate -k below. Note that in recent versions of this program, the option you want has changed to nsupdate -y. You will find an example of the new format later in this

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.

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 10.5.0.20… telnet: connect to address 10.5.0.20: Operation timed out telnet: Unable to connect to remote host I started

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 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
