C Programming under Tru64 UNIX

A crash course in C programming under Tru64 UNIX :-). You've got a text editor - ed(1), of course, make(1), install(1) and a C compiler - cc(1) - and you're good to go.

Don't like ED? Well, Tru64 also comes with vi and XEmacs by default, so no worries.

All you need to do now is write a Makefile:

% ed Makefile

hello: hello.o
$(CC) -o $@ $<

hello.o: hello.c
$(CC) -c -o $@ $<

rm -f hello hello.o

% make
cc -c -o hello.o hello.c
cc -o hello hello.c
% ls
Makefile hello hello.c
% hello
Hello, Tru64 UNIX!
% make clean
rm -f hello hello.o
% ls
Makefile hello.c

Building Git Version Control System on AIX, HP-UX and Solaris

Git is a fast version control system originally designed for the Linux kernel and written by Linus Torvalds.
Need git on AIX or HP-UX? Here's how:


First, you're going to need a compiler (GCC), GNU make (gmake) and GNU coreutils (install). swinstall the dependency repositories first:
coreutils 6.9 coreutils
gcc 4.2.3 gcc
libgcc 4.2.3 libgcc
libiconv 1.12 libiconv
make 3.81 make
perl 5.8.8 perl
zlib 1.2.3 zlib

Untar the package and start building:

$ ./configure --with-iconv=/usr/local/bin

Edit the Makfile:

CC = gcc
AR = ar
RM = rm -f
TAR = tar
FIND = find
INSTALL = /usr/local/coreutils/bin/install

# sudo gmake NEEDS_LIBICONV=1 NO_TCLTK=1 install prefix=/usr/local

$ which git
$ uname -sr
HP-UX B.11.11
$ git --version
git version

Building GIT on AIX 5.3 POWERPC:

Install dependencies and GCC, gmake, GNU coreutils (install), etc:

gcc-4.0.0-1 libgcc-4.0.0-1 libstdc++-4.0.0-1 libstdc++-devel-4.0.0-1 gcc-c++-4.0.0-1 readline-4.3-2 readline-devel-4.3-2 zlib-1.2.3-3 zlib-devel-1.2.3-3 make-3.80-1 unzip-5.51-1 flex-2.5.4a-6 bison-1.875-3 popt-1.7-2 gettext-0.10.40-6 expect-5.42.1-3 tcl-8.4.7-3 tk-8.4.7-3 coreutils-5.2.1-2

$ ./configure

vi Makefile:

CC = /opt/freeware/bin/gcc
AR = ar
RM = rm -f
TAR = /opt/freeware/bin/tar
FIND = find
INSTALL = /usr/linux/bin/install
RPMBUILD = rpmbuild
TCL_PATH = /opt/freeware/bin/tclsh
TCLTK_PATH = /opt/freeware/bin/wish

# gmake NO_MSGFMT=1 install prefix=/opt/freeware

$ uname -a
AIX aix 3 5 004518FC4C00
$ which git
$ git --version
git version

Solaris 10:

Solaris 10 comes with gcc, gmake and GNU tools in /usr/sfw/bin, but you'll need ginstall from GNU coreutils (you can get it from Solaris Freeware).

$ ./configure

Edit the Makefile - set the path to "ar", "gcc" and GNU "install".

CC = /usr/sfw/bin/gcc
AR = /usr/ccs/bin/ar

RM = rm -f
TAR = tar
FIND = find
INSTALL = /opt/sfw/bin/install

Look for ifeq ($(uname_S),SunOS) and set INSTALL to /opt/sfw/bin/install also.

# gmake NO_TCLTK=1 NO_CURL=1 install prefix=/opt/sfw

% uname -a
SunOS ibmsolaris 5.10 Generic_127112-11 i86pc i386 i86pc

% git --version
git version

IBM Lotus Symphony - Free Office and Productivity Suite built on Eclipse

IBM Lotus Symphony is a free ODF (Open Document Format) compatible Office suite from IBM. It comes with a word processor, a presentation application and a spreadsheet application (basically replacements for Words, Excel and Powerpoint).

It's a nice change of pace from StarOffice / OpenOffice, and it's free for both Windows and Linux platforms.

Lotus Symphony is build on the Eclipse platform, and you can use Eclipse to develop various plugins and addons.

It can also open .doc files written by Office 97,2000,XP and 2003:

Powerpoint presentations and even OpenOffice presentations:

And of course .xls files:

Runing Solaris SPARC software on x86-64

You can run Solaris SPARC software on Solaris x86-64 (and even Linux x64 and Itanium).

Here is Solaris 10 u4 x86-64 running Acrobat Reader 8.1.2 SPARC via Transitive QuickTransit Solaris/SPARC to Solaris/x86-64 cross-platform virtualization.

Install QuickTransit, start the daemon and run SPARC software. It's as easy as that.

# /etc/init.d/QuickTransit start
Starting /usr/sbin/cron
cron is already running

% uname -simpr
SunOS 5.10 i86pc i386 i86pc

So performance on my Intel(R) Pentium(R) 4 CPU 3.40GHz LGA775 is on par with a UltraSPARC running at 700Mhz or so. Still, that's pretty good.

The best part is, you can run SPARC-only software like this NX client:

OpenGL DooM on Solaris

Nothing quite like DooM to start the day :-).

prboom, an open source OpenGL DooM engine works quite well on Solaris, and it can be used with any DooM or Hexen / Heretic .WAD file (including some opens source content like FreeDOOM).

If you want fully open source content, you can use ioQuake3 + OpenArena or prboom and FreeDOOM.

So there you go, StarCraft, Quake 1,2,3, OpenArena, Doom 1,2, Heretic, Hexen and just about any DS game (FreeDOS / DOSBOX) will work just fine on Solaris. Not to mention things you can with Wine or just fine in VirtualBox.

StarCraft on Solaris 10

Want to play some games other than nethack or quake 1/2/3 on Solaris 10? Try this:

While you can also use Wine or some emulator, or VirtualBox virtualization, rdesktop will work just as well:

% /opt/csw/bin/rdesktop -T StarCraft -D -b -E -a 8 -x l -5 -g 640x480 SomeWindowsBox
If you want to play in full screen mode (-f) you're going to have to set your resolution to 640x480 :-).
% /opt/csw/bin/rdesktop -D -f -T StarCraft -b -E -a 8 -x l -5 -g 640x480 SomeWindowsBox

Windows Vista Service Pack 1 - Standalone and Windows Update released

Windows Vista Service Pack 1 was released to the general public via Windows Update and as a Standalone pack.

Download Windows Vista SP1.

Skype VoIP on Solaris using BrandZ + CentOS Linux

Now that we've got a CentOS BrandZ Linux container and OSS audio drivers on Solaris, we can run Skype on the BrandZ container, and ssh -X skype. Of course, it's a lot easier if you're emulating Linux 2.6 and running CentOS 5 or some newer distribution, but let's stick to more "tested" software for the moment.

You're going to have to install the dependencies first:
# yum install libstdc++-ssa

And so on.

And you're going to have to use and older version of Skype. But no worries. At least it gets the job done.

Sound Drivers on Solaris 10

If you need audio on your Solaris 10 workstation, you can install OSS - Open Sound System.

# pkgadd -d oss-solaris-v4.0-1014-i386.pkg
Open Sound System installation complete
# osstest
Sound subsystem and version: OSS 4.0 (b1014/200802281506) (0x00040003)
Platform: SunOS/i86pc 5.10 Generic_127112-10

*** Scanning sound adapter #-1 ***
/dev/oss/ich0/pcm0 (audio engine 0): Intel ICH7 (27DE)
- Performing audio playback test...

*** All tests completed OK ***

You may need to log out of JDS and log in again to get the mixer working (or just restart the widget).

Mounting Linux NFS shares in Solaris 10

First, export a filesystem on your Linux box (add it to the exports file, and exportfs). Make sure the kernel-nfs server service is started.

# /etc/init.d/nfs-kernel-server start
Edit your exports file:
# ed /etc/exports
Export the filesystem:
# exportfs
# showmount -e
Export list for loonix:

On your Solaris 10 box, run:
# showmount -e loonix
export list for loonix:
It should give you results consistent with the results you got on your Linux machine.
Trying to mount the share as NFSv4 will fail (Linux NFSv4 isn't compatible with Solaris NFSv4).
# mount loonix:/home/cmihai /storage
nfs mount: mount: /storage: Not owner
So we're going to mount the share as NFSv3:
# mount -o vers=3 loonix:/home/cmihai /storage
# mount
/storage on loonix:/home/cmihai remote/read/write/setuid/devices/vers=3/xattr/dev=4840010 on Tue Mar 18 14:59:06 2008

BrandZ - Linux Branded Zones in your Solaris 10 Containers

You can easily create a Linux branded container and install Debian, CentOS or some other Linux distribution inside your Solaris container.

# zonecfg -z loonix
loonix: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:loonix> create -t SUNWlx
zonecfg:loonix> set zonepath=/export/loonix
zonecfg:loonix> add net
zonecfg:loonix:net> set address=
zonecfg:loonix:net> set physical=bge0
zonecfg:loonix:net> end
zonecfg:loonix> commit
zonecfg:loonix> exit

We can install from a tar image, a CD or DVD or even a .iso file.

# zoneadm -z loonix install -d /export/home/cmihai/Desktop/centosimg/centos_fs_image.tar
Installing zone 'loonix' at root directory '/export/loonix'
from archive '/export/home/cmihai/Desktop/centosimg/centos_fs_image.tar'

This process may take several minutes.

Setting up the initial lx brand environment.
System configuration modifications complete.

Installation of zone 'loonix' completed successfully.

Details saved to log file:

# zoneadm list -iv

- loonix installed /export/loonix lx shared

# zoneadm -z loonix boot
# zoneadm list -iv

# zlogin loonix
[Connected to zone 'loonix' pts/9]

Welcome to your shiny new Linux zone.

- The root password is 'root'. Please change it immediately.

- To enable networking goodness, see /etc/sysconfig/network.example.

- This message is in /etc/motd. Feel free to change it.

For anything more complicated, see:

You have mail.

-bash-2.05b# passwd
Changing password for user root.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

-bash-2.05b# ed /etc/sysconfig/network

Now we can ssh in :-).

Back in the global zone, a simple prstat -Z 1 1 reveals memory usage:

0 87 466M 568M 14% 0:40:04 5.7% global
1 11 7724K 12M 0.3% 0:00:00 0.0% loonix

As you can see, Solaris Zones are *very* lightweight.

There is also a Linux 2.6 BrandZ project, so we can easily run RHEL 5 or any other Linux distribution of our choice (with a bit of work).

ES40 - OpenSource Alpha AXP Emulator

I've already posted about other free Alpha or VAX emulators like PersonalAlpha (the free version of CHARON-AXP, also makers of CHARON-VAX) and SIMH. Now it's time for something open source, that will work on Windows and UNIX systems.

AlphaServer ES40 Emulator is a portable emulator for the HP (DEC, Compaq) AlphaServer ES40. The current version is capable of running OpenVMS with some limitations. The goal is to have a drop-in replacement for real ES40's. Emulates the Alpha AXP EV68CB processor and other devices.

Now you can run OpenVMS or Tru64 UNIX on your own personal computer.

The advantage of ES40 over PersonalAlpha is that you can emulate EV68 CPUs and a more modern system (AlphaServer ES40) and additional hardware. It's also open source, and will run on your Windows, Linux and UNIX machines. The problem is, it's no match for CHARON-AXP or PersonalAlpha in terms of performance.

You can even use ES40 to install other operating systems like BSD and Linux on Alpha.
Here's FreeBSD/alpha 6.3-RELEASE

Communigate Pro - Mail and Communications on OpenVMS

Communigate Pro is by far one of the best communications suite, and can easily replace even an Exchange / LCS / OCS suite (Unified Communications and all that). It can do clustering, VoIP, interface with Windows phones and has integrated WebMail, mailing lists, and so on.

The installation is pretty straight forward too. First, disable OpenVMS POP3 and IMAP services, and make sure nothing is running on port 8010 and 8100. Then unzip and proceed to install the POLYCENTER package.


Once the installation is over, start CommuniGate Pro services and login to the administrative interface withing 15 minutes. Enjoy.


The WebMail is pretty nice too:

It also has Calendar function and a few themes (the XCHANGE one looks like OWA from Exchange).

By default, CommuniGate Pro supports the following features:

+ Mail + POP + IMAP + PWD + ACAP + WebMail + WebSite + Relay + Mobile + FTP

Here's a screenshot of the WebMail SSL (HTTPS) interface with the XCHANGE skin:

So now you can have a fully encrypted, secure, highly available enterprise communications suite with E-Mail and VoIP features on your OpenVMS cluster :-).

HP OpenVMS Secure WebServer (Apache)

Now that we've tested WASD, we can also try HP Secure WebServer (ex Compaq WebServer). It's basically Apache + SSL and OpenVMS patches.

FTP upload or download or get the packages on the server.

WASD VMS Hypertext Services

Time to take a look at the "non-stop webserver", aka WASD VMS Hypertext Services.

To install this webserver, we're going to need the compiler suited we've previously installed (C and CXX-V products).

To install WASD, you need to download and unpack 2 images: HTROOT921.ZIP, the platform independent pack, and HTROOT921-AXP.ZIP (or VAX or IA64) - the platform specific files.

The installation process will largely go like this:

$ SET DEFAULT DKA0:[000000]
$ UNZIP "-V" SYS$SYSROOT:[SYSMGR.wasdkit]htroot921-axp.zip;1


The INSTALL procedure will take a while to compile then link the package. If you do not have the OpenVMS SSL product (Compaq/HP) you'll require the OpenSSL toolkit.

The C Programming Language

To program using the C Programming Language on OpenVMS, you need the DEC C compiler.

$ run CC073.DCX_AXPEXE;1
* Products: *

Then we test it:


#include "stdio.h"
int main()
printf("Hello, OpenVMS CC!");

return (0);

[End of file]

Hello, OpenVMS CC!

C++ is similar, but you need CXX instead of CC.

Kicking it up a gear with Oracle Rdb Server on OpenVMS

$ show system
OpenVMS V8.3 on node DEIMOS 8-MAR-2008 16:15:25.04 Uptime 0 13:09:50

Time to install a database server on this box :-). And nothing says "database" quite like Oracle Rdb (ex DEC product btw).

Grab Oracle Rdb, unzip it (unzip SYS$SYSROOT:[SYSMGR.RDBKIT]rdbv72200kit_amv.zip;1), and install it :-).


Now we can restart the service, and create our database.


$ UCX show services

$ run SYS$SYSTEM:SQL$72.exe
Current version of SQL is: Oracle Rdb SQL V7.2-200

cont> );
SQL> INSERT INTO clients VALUES ('1','Some','Guy');
1 row inserted

1 row inserted
SQL> SELECT * from clients;
1 Some Guy
2 Other Bloke
2 rows selected

All we have to do now is fire up Phobos and cluster them :-).

If you install SQL Services on the database server, you can install the Rdb Client on your Windows box in order to administer Oracle Rdb on OpenVMS.

GNU Screen for the win! - Solaris, AIX, HP-UX

I really love the hardstatus line in .screenrc :P. Just upgraded this machine to 8.3 too, so don't mind the title. (C-a A - OpenVMS-8.3) xD

Credits for the .screenrc hardstatus line go to Han:

Wallpaper is some image off flickr + GIMP + my favorite palindrome:
In girum imus nocte, ecce et consumimur igni.
We enter the circle by night and we are consumed by the fire.
(Drawn like moths to a flame).

By popular demand:

GNU Screen works just fine with that hardstatus line even on HP-UX systems. One thing I did though, was use:

env TERM=xterm-color screen

To start screen after ssh-ing in. After screen starts, you'll probably want:

TERM=vt100; export TERM

Also. You can put them in your profile. Using TERM=screen doesn't always work well.

Of course, you can just use TERM=dtterm, or even use dtterm, as done here via ssh -X to my AIX server :-).

As you can see, the AIX and HP-UX versions need a bit more work (or a fixed sized terminal in case of AIX):

Runnig Symantec Veritas Cluster Server on Windows Vista 64bit

Getting Veritas Cluster Server Simulator (VCS Simulator) to install and run can be a bit of a pain. Here's the deal:

Start a command prompt as Administrator, and install it using:

msiexec /i vcs_simulator.msi

Once the software is installed, download MSVCR70.DLL and put it in the VCS directory (C:\Program Files (x86)\VERITAS\Cluster Manager\bin\).

Then run "Veritas VCS Simulator - Java Console" and "Veritas Cluster Manager - Java Console" as Administrator (Right Click - Run as Administrator) and unblock the Windows Firewall ports (allow exception).

Enjoy playing with Veritas clusters :-).

public static void main(String args[])
System.out.println("Hello, OpenVMS!");

^Z (Type Control Z to save and exit)

class hw
public static void main(String args[])
System.out.println("Hello, OpenVMS!");


Hello, OpenVMS!

Enjoy your ancient version of Java...

PS: Once you've had your fun, just download JDK 1.5 :-).

My hovercraft is full of eels

Hooray for Monty Python:
%SYSTEM-E-FISH error on OpenVMS 7.3. It's an Easter Egg btw. There's more (make love -> not war, etc) in other versions :-).

VPNC - Open Source client for Cisco VPN Contentrator

Got an ASA, a PIX or some other VPN Concentrator (or even Juniper NetScreen)? Well, you'll run into some troubles sooner or later. The Cisco VPN Client doesn't support 64 bit Windows clients, x86 Solaris clients and is just a pain to use on Linux.

VPNC doesn't require any kernel modules. Just put the IPSec gateway IP, IPSec ID, IPSec secret and XAuth username into /etc/vpnc/default.conf and start vpnc. It should work instantly :-). No fuss, no mess.

It will work just fine on Solaris, Linux, MacOS X or BSD machines. You can even get it running on your Windows box (Cygwin libs).

TrueCrypt now does pre-boot authentification

TrueCrypt is an open source on the fly (transparent) whole disk encryption software for Windows, Linux and MacOS that now supports pre-boot authentication on Windows. This means you can use this to replace PGPDisk or BitLocker.

It supports AES-256, Serpent and Twofish encryption, hidden volumes with two levels of plausible deniability and hidden volumes.

Tunneling over ICMP, DNS, HTTP and HTTPS proxies

Stuck beyond a firewall, captive portal or proxy and need your ssh (or any other service)? Here's a few ways to tunnel out:

  • PTunnel - Tunnel TCP using ICMP echo request and reply packets (PING), includes authentication, allows for multiple connections.
  • Iodine - tunnel IPv4 data through a DNS server, allows for authentification.
  • NSTX - Tunneling network packets over DNS.
  • Corkscrew - tunneling SSH through HTTP proxies.
  • httptunnel - bidirectional virtual data connection tunnelled in HTTP requests.
  • gotthard - ssh through https proxy tunnel
I've already mentioned Shared Shell and such too :-).
