If you're planning to use OpenSolaris as an RMI server, this little tip could save you some time. As a simple test I was following the Getting Started Using Java RMI tutorial. However, when I attempted to connect to the OpenSolaris server from the client, I was getting the following exception: Client exception: java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is: java.net.ConnectException: Connection refused: connect Why was RMI trying to...

Chime is a tool that all users of OpenSolaris should take the time to install. Chime is a graphical user interface for DTrace that makes viewing DTrace output enjoyable. It has traces that can provide valuable feedback on your system (and you don't even have to know DTrace to use it). For example, take this simple script that aggregates the system calls over the period of time the script is run: bleonard@os200906:~$ cat syscalls_overtime.d syscall:::entry{@a[execname] =...

Installing a zone in OpenSolaris requires a network connection and some patience as a little over 70MB of data is downloaded. Fortunately, after you've got the first zone installed, future zones can be cloned. This is not only quicker than an IPS install but it's also a much more efficient use of disk space. In addition, if you've customized a zone with additional software (or less software), that will also come along with your clone. The 4 step creation process is almost...

If you're like me and working with zones on your laptop and/or desktop, you probably only have one network interface card to work with. Therefore, the zones I've created share the single network interface with the global zone (ip-type=shared). Behind the scenes, Solaris creates a logical interface for the zone to use. The logical interface appears in ifconfig as your physical interface with an instance number. For example: bleonard@solaris:~$...

If you've preconfigured your zone as I did, you will probably be frustrated that there's no DNS. For example: root@myzone:~# pkg search glassfishpkg: Some servers failed to respond appropriately: http://pkg.opensolaris.org/release/: node name or service name not known This is easy enough to fix. First, copy the global zone's /etc/resolve.conf file to myzone: bleonard@opensolaris:~$ pfexec cp /etc/resolv.conf /zones/myzone/root/etc/. Then, in the zone, copy /etc/nsswitch.dns...

In the Zones blog I posted a few weeks back, a couple of the steps required interactive configuration. In this entry I'm going to create the same zone, however in a much streamlined manner. Step 1: Create the Zone In this step we can pass a series of settings to the zonecfg command, bypassing the interactive prompts. I've created a file called myzone.config that contains the following: bleonard@opensolaris:~$ cat myzone.configcreateset zonepath=/zones/myzoneset...

How cool would it be to see this the next time you travel? I watched Iron Maiden's latest documentary this past weekend, Flight 666. What I found most impressive was that lead singer Bruce Dickinson pilots the tour plane! This is a Boeing 757 - not some simple Cessna. And If you've seen him on stage you'll wonder where he finds the energy to then fly a plane from Tokyo to Los Angeles. So, what's any of this got to do with OpenSolaris? A friend of mine turned me on to the Iron...

About 25 people attended the July meeting of the Connecticut OpenSolaris User Group on July 1st. Ken Baer assembled a nice list of speakers: Steve Putre of F3 Technology Partners led off with what's new in OpenSolaris 2009.06. OS Ambassador Jeff Victor came in from NY to discuss cool and practical uses for Solaris Containers. Dave Donmoyer came down from New Hampshire to talk about Solaris clustering, including Open HA Cluster. And Elizabeth Matthis came all the way from the...
