QNX Updates

(this is a guest post by Tenox)

A few interesting things have happened in QNX area in a last month or so.

First of all, there is a QNX BSP for Raspberry PI:

qnxrpiIt’s an early developer release, not fully complete, but it does boot and work. It adds an interesting os beside RISC OS and Plan9 to the Pi family. The BSP is available from SHC Products. They have a binary and source code version.

Secondly, in the archaeology department, this has surfaced:

qnx12bootqnx12c

But even more interestingly I’ve found a beta / preliminary release v0.4 of QNX:

qunixCan’t wait to get the disk images ūüôā

 

Blue Lion

While I was sleeping this happened:

That is right, a new re-release of OS/2. ¬†But don’t go all too crazy the targeted release date is Q3 2016.

That being said, they don’t apparently have source code, so yeah. ¬†Me? ¬†I still run OS/2 2.0, and I really don’t see much need in upgrading. ¬†It runs MS-DOS just fine. ¬†At the same time, I really wonder how much IBM charges to brand out your own version of OS/2? ¬†Not that I really need one.

PHP 5.4 is now obsolete on Debian

While doing an update, I got this fun message:


php5 (5.4.45-0+deb7u2) wheezy-security; urgency=medium

* PHP 5.4 has reached end-of-life on 14 Sep 2015 and as a result there
will be no more new upstream releases. The security support of PHP
5.4 in Debian will be best effort only and you are strongly advised
to upgrade to latest stable Debian release that includes PHP 5.6 that
will reach end of security support on 28 Aug 2017.

Time to upgrade!

After a bit of digging around here is how I did it. ¬†I’m moving from PHP 5.4 to PHP 5.6


# php --version
PHP 5.4.45-0+deb7u2 (cli) (built: Oct 17 2015 09:01:48)

Ok, so here is the version I’m starting with on Debian 7.9 (Wheezy). During this process, I’m using unsigned packages so get used to this fine message, and packages being held back, unless I manually install them:


Reading package lists... Done
W: GPG error: http://packages.dotdeb.org wheezy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E9C74FEEA2098A6E
W: GPG error: http://packages.dotdeb.org wheezy-php56-zts Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E9C74FEEA2098A6E
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

But if you can read this, then it worked!

First add these to the /etc/apt/sources.lst file:

deb http://packages.dotdeb.org wheezy all
deb-src http://packages.dotdeb.org wheezy all
deb http://packages.dotdeb.org wheezy-php56-zts all
deb-src http://packages.dotdeb.org wheezy-php56-zts all

Then we can run the usual apt-get update / apt-get upgrade shuffle.

On my first run I got this fun output:


The following packages have been kept back:
libapache2-mod-php5 libmysqlclient18 mysql-server php-pear php5 php5-cli
php5-common php5-gd php5-mysql
The following packages will be upgraded:
mysql-common
1 upgraded, 0 newly installed, 0 to remove and 9 not upgraded

So I went ahead and updated mysql-common.  And during that upgrade I got the new message:


WARNING: The following packages cannot be authenticated!
mysql-common
Install these packages without verification [y/N]? y

So yes these packages are all unsigned. ūüôĀ

After this, I ran:


# apt-get install php5

And got the following scary looking output


The following extra packages will be installed:
libapache2-mod-php5 libt1-5 libvpx1 php5-cli php5-common php5-gd php5-mysql
Suggested packages:
php5-user-cache
Recommended packages:
php5-readline
The following NEW packages will be installed:
libt1-5 libvpx1
The following packages will be upgraded:
libapache2-mod-php5 php5 php5-cli php5-common php5-gd php5-mysql
6 upgraded, 2 newly installed, 0 to remove and 3 not upgraded.
Need to get 7,659 kB of archives.
After this operation, 5,220 kB of additional disk space will be used.
Do you want to continue [Y/n]? y
WARNING: The following packages cannot be authenticated!
php5-mysql php5-cli php5-gd libapache2-mod-php5 php5-common php5
Install these packages without verification [y/N]? y

And then finally, after another apt-get update / apt-get upgrade I finally get this output:


The following packages have been kept back:
libmysqlclient18 mysql-server
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

So just update the held back packages and get it over with.


apt-get install libmysqlclient18 mysql-server

Ugh, it isn’t pretty. ¬†But now we are on the newer train of PHP!

Hopefully things continue to work.

DooM shovelware CD archive!

DooM!

DooM!

In the mid 90’s the CD-ROM format was becoming insanely popular, and seen as a ‘get rich quick’ scheme for a brief time. ¬†And of course one of the greatest, customizable games ever, DooM is from that era! ¬†Combine the two, and you have an awesome collection of shovelware CD’s featuring DooM utilities, mods, and levels!

Perhaps one of the more popular CD-ROM distributors was Walnut Creek, which had a good relationship with FreeBSD.  Oddly enough it would eventually merge with BSDi, and split, merge, acquire, become acquired by others.

Archive.org has their massive CD-ROM collection online!  And, it of course includes the DooM 1994 CD.

I personally prefer PCem over DOSBox at the moment, as PCem runs the actual BIOS code, so it feels more like an actual vintage PC.  PCem does need a significantly more powerful machine to push it thought.

 

The client needs to access the internet!

But let’s not give them access to everything.

This is a common scenario I see, where someone needs to get updates to some magical software package on the internet.  Great.  And people just give them access to ANY site, which ends up being not only the internet (the intended destination) but the rest of their internal network.  Granted a good defense in the SDN world is inbound rules as well for each VM, but everything is never 100%.

RFC1918 defines our friends, the private address ranges:

     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)

However the solution to this fun filled problem is to grant them HTTP/HTTPS access to the inverse of this. ¬†Enter the netmask command. ¬†You can give it a range, and it’ll lay out what networks to you need to add like this:

     netmask -c 0.0.0.0:9.255.255.255
     0.0.0.0/5
     8.0.0.0/7

Now I can exclude everything right up until 10.0.0.0/8 !

It’s quite the handy tool, but I didn’t see any Windows version. ¬†So a few minutes with MinGW, and dealing with it’s weird Makefile’s way of linking things, and here you go!

This way you can permit internet access, not give them inside, access and still have a global DENY actually work.

YAY.

And if anyone is interested here are the networks:

     0.0.0.0/5
     8.0.0.0/7
    11.0.0.0/8
    12.0.0.0/6
    16.0.0.0/4
    32.0.0.0/3
    64.0.0.0/2
   128.0.0.0/3
   160.0.0.0/5
   168.0.0.0/6
  172.0.0.0/12 
 172.32.0.0/11
 172.64.0.0/10

   173.0.0.0/8

Yes, I know it’s a LOT of typing.

You can run VxWorks too!

(this is a guest post from Tenox)

VxWorks is an embedded operating system that typically runs on things like Mars probes, Boeing 787 or Apache helicopters, but today you can run it too! WindRiver has an evaluation target that you can run on an Intel CPU, meaning you can spin it up on your favorite hypervisor at home.

Go to this page: http://www.windriver.com/evaluations/bsp/ register, download the two ZIP files and follow the instructions.

VxWorks running on VMwareVxWorks comes with two shell modes C and admin. In C shell you execute C code and you can write simple programs or even patch existing running code like they did on Mars Pathfinder. This is the default one with -> prompt. You can enter to admin shell by typing “cmd”. If you are familiar with KSH “vi” mode you can use it for history and editing command line.

The evaluation target is very basic and limited. If you want to do and learn more stuff, you need to download evaluation of VxWorks Platform and spin up the VxWorks Simulator, or build your own target. This is a picture of a slightly older version running on Windows:

20 years of OpenBSD

puffy58Yes, 20 years!

The list announcement:

OpenBSD's source tree just turned 20 years old.

I recall the import taking about 3 hours on an EISA-bus 486 with 
two ESDI drives.  There was an import attempt a few days earlier, 
but it failed due to insufficient space.  It took some time to 
repartition the machine.

It wasn't terribly long before David Miller, Chuck Cranor and 
Niklas Hallqvist were commiting... then more people showed up.

The first developments were improvements to 32-bit sparc.

Chuck and I also worked on setting up the first 'anoncvs' to make 
sure noone was ever cut out from 'the language of diffs' again.
I guess that was the precursor for the github concept these 
days :-).  People forget, but even FSF was a walled garden at 
the time -- throwing tar files with vague logs over the wall 
every couple months.

I was lucky to have one of the few 64Kbit ISDN links in town,
otherwise this would not have happened.  My desktop was a 
Sparcstation 10; the third machine I had was a very slow 386.

The project is now at:

~322,000 commits
~44 commits/day average
~356 hackers through the years

I thought I’d try OpenBSD 2.0 SPARC on Qemu! ¬†Well either with SUN PROMs, or OpenBIOS the result is the same, it crashes when initializing the SCSI bus.

But make no mistake, the new 5.8 release (just released!) boots up just fine on Qemu:
