Solaris 11 as an NFS client to Linux

Other strangeness again, but I am not going to blame it on Solaris this time 🙂 I was trying to make my Solaris workstation an NFS client to the Linux machine (the other way round compared to what I did months ago). /etc/exports was well configured on the Linux side, and I could actually mount my home directory from the machine itself:

mount localhost:/export/home/bronto /mnt

worked just fine. However, when I tried mounting from Solaris, I got a "No such file or directory".

After some research, it turned out that Solaris attempts to use NFSv4 by default; Linux NFS server has NFSv4 enabled, but the share was not exported with that protocol (only in NFSv3). So I could either export the share in NFSv4, or force Solaris to use NFSv3. I was short on time so I chose the second solution.

My /etc/auto_home now looks like this:

# Home directory map for automounter
bronto  -vers=3 linuxws:/export/home/&

and that just works. But I guess I'll be trying the NFSv4 version soon in the future 🙂


My first puppet facts

An apparently simple problem: have puppet manage an host's own entries: the localhost one, and the hostname's one. Well, we have plenty of facts to help us with this: we have ipaddress, and hostname, and fqdn. It should be simple, right?

But think. What happens if the host is multihomed? What if one of the interfaces is a bond interface? Does facter choose a value for ipaddress in a smart way?

Unfortunately, it doesn't. And to make it smart, you have to feed it the right thing. And to feed it, you need to write code in Ruby. Oh oh…

I decided to give it a try, and to pull in some shell script to actually do the job (bad thing, I know, but I really don't have time to learn ruby; and when I'll use some time to learn another programming language, I'd go through python and perl 6 first). … Continue reading

Testing Oracle Solaris 11 Express

I've been testing Oracle Solaris 11 Express recently. For those who don't remember it, Oracle acquired Sun Microsystems :rip: and killed OpenSolaris :rip: with no official statement, the only information about the process was a leaked internal note (I leave it to you to decide whether that that leakage was real, and if it was intentional or not).

Solaris 11 Express is what remains of OpenSolaris after Oracle decided how they should move forward with it.

The immediate change you may notice in case you want to download and test it is that the license has changed, and that you are not allowed to download it unless you explicitly accept the license. Up to my knowledge, the license allows you to use it for free for personal use, otherwise you need to buy some sort of support; I didn't investigate this further because, well, I am interested in it for personal use at the moment. Why? Well, many reasons. … Continue reading
