pip installing jupyterlab may give you the following error (somewhere in the error output anyway!): The simplest solution I’ve found to this is just to install libzmq. We can pull the latest code from github and install it. I usually install things in /opt but as the pip process will look for libzmq in /usr/local, we’ll install it in there this time. If you do put it somewhere other than /usr/local you might need to Read more
I’ve forgotten this several times now so it’s time I wrote a short post to help me remember in future! In Solaris 11 we use the Image Packaging System to maintain the software on the system. This is written in python and uses libcurl and for non zoned systems setting the http_proxy is sufficient to allow the system to communicate with the repo. Read more
… or Overcoming Your Fear of Repositories as the OTN Garage puts it! My colleagues Glynn Foster, Pete Dennis and I have put three articles on Oracle Tech Network that we hope will help you keep your Solaris 11 systems up to date. Here’s why these documents may be of interest to you administering Soalris 11.
‘boot -L’ will give you the list of boot environments to boot from. So then you can just use the -Z option to boot the corresponding root fs.
Handy when you screw up boot environment activation 🙂 Read more
I’ve been using my tonidoplug as a home NAS server for almost a couple of years now. It’s performed as well as can be expected for 2 mirrored 1.5TB disks attached on a USB hub. One evening recently though I noticed that it was unreachable. A quick look at the box showed that all was not well, both lights on the network interface were on as was the green light on the box. After trying Read more
This post originally appeared at http://blogs.sun.com/ford/entry/using_nat_in_the_global Since sun.com is going away soon (thank a bunch Oracle…) I’m going to mirror it here because I found it useful. Tuesday September 27, 2005 Using NAT in the Global Zone There have been requests to use IPFilter on Solaris 10 as a tool to allow use of networking by non-global zones without allocating an IP address for each zone. The general idea is to use network address translation Read more
I came across a strange little networking problem earlier today. The client in question had needed to be rebooted earlier in the day. The server had had no changes made to it. The problem only started occurring after the reboot of the client. We had an NFS directory on the server that the client’s subnet had access to. However when we tried to mount the directory (via the automounter) it failed with a permission denied Read more
Another ‘damn! I keep forgetting how to do that!’ post… When you want to display something from one unix box to another there are two ways of doing it. 1. Use ssh. You need to use ‘ssh -X’ specifically which will allow X11 forwarding. ssh takes care of setting the DISPLAY variable for you. You also need to ensure that the server is configured for X forwarding: [sourcecode language=’php’]# X11 tunneling options X11Forwarding yes X11DisplayOffset Read more
Every now and again an install on a new machine fails for me and I have to google to remember how to change the label. So this time I’m writing it down! Docs.sun.com has some information on the differences between the two formats http://docs.sun.com/app/docs/doc/817-5093/disksconcepts-47761?l=en&a=view But suffice to say that you cant install Solaris on an EFI disk, you need to change it to an SMI label. Thats done using ‘format -e’. Select the label option, Read more
Opensolaris users may be familiar with browsing repositories in firefox. To look through the latest Develpoment repo for example you just open up http://pkg.opensolaris.org/dev in your browser. Things are a little more complicated for the extras and support repos though. Firstly you need to register to get access to these repos. Anyone can get access tot he extra repo, only supported customers can get access to the support repo. Go to http://pkg.sun.com/register and follow the Read more
