FreeNX on FreeBSD

While stumbling around the Internet today I came across a VNC (RealVNC, TightVNC, Ultr@VNC, etc.) replacement called FreeNX. NX is a remote display technology developed by NoMachine and FreeNX is a free GPL based server with packages available for Debian/Ubuntu, Fedora/RedHat, FreeBSD, Gentoo, and Suse.

I installed the FreeNX server from the available FreeBSD port (/net/freenx) but had to take some additional steps to configure it. A special thanks goes out to Marc Abramowitz for his how-to for version 4.10 of FreeBSD. I used his how-to as a guide but did not have to follow all of the steps he described to complete the installation on FreeBSD 6.0.

First, install the FreeNX server via package by running:

# pkg_add -r freenx
or from source by running:
# cd /usr/ports/net/freenx && make install clean

This will install the FreeNX server along with any required dependencies. Next you will need to create the nx user. I followed Marc’s example and created the user as follows:

# pw user add nx
# pw usermod nx -s "/usr/X11R6/NX/bin/nxserver"
# passwd nx

After you enter and confirm a password your nx user, you can verify that your FreeNX server is installed and that you configured the nx user successfully by changing to that user and verifying the default shell for nx. Type su nx at the command line and you should see something similar to the following. To exit the server and log out of the nx account, type quit. You’ll see where I did this after the NX> 105 prompt below.

# su nx
Password:
HELLO NXSERVER - Version 1.4.0-44 OS (GPL)
NX> 105 quit
quit
Quit
NX> 999 Bye

Now all we need to do is configure the server using the following commands:

# cd /usr/X11R6/NX/bin/
# ./nxsetup --install --setup-nomachine-key

This will configure the server and ready it for use with local user accounts. As best I can tell, all communications between the FreeNX server and the client are tunneled over SSH so all of your communications will be encrypted. Now, all you need is a client to connect to your FreeNX server. You can download an NX client from the NoMachine web site free of charge. There are clients available for Windows, Linux, Mac OSX, and Solaris.

Ok, nxserver is ready.
PAM authentication enabled:
All users will be able to login with their normal passwords.
PAM authentication will be done through SSH.
Please ensure that SSHD on localhost accepts password authentication.
You can change this behaviour in the /usr/X11R6/NX/etc/nxserver//node.conf file.
Have Fun!

Cpufreq - AthlonXP Mobile

- moodx - I have a mobile athlon xp running in an abit nf7-s, I'm looking for a cpu program that interfaces with some hardware in order to scale the CPU speed.
- Caelian - moodx, kldload cpufreq
- Caelian - moodx, i believe you can fiddle with it through sysctls ... but most likely any cpu-applet for the major desktop environments can interact with it as well
- moodx - thx Caelian !

KDE-Lite or /usr/ports/x11/kdebase3

KDE-lite is simply a metaport for KDE. It doesn't make KDE faster or more trimmed down, it just installs certain KDE ports instead of just about all of them. I use KDE all the time, and what I do on a fresh install is # cd /usr/ports/x11/kdebase3 # make install clean That will pull in the bare minimum you need to run KDE (qt, aRts, kdelibs3, cups, etc.). Then you just need to: a) Have exec startkde in ~/.xinitrc b) $ ln -s ~/.xinitrc ~/.xsession Also look at ports/UPDATING 20041229 for important information about using KDE with X.org. Then after you have the base in, you can just pick and choose whatever KDE packages you want. IMO, that's even better than installing KDE-lite.

Visit XS4ALL's Self Service Centrum (click "IPv6 Tunnel", unfortunately no direct link) to have an IPv6 tunnel configured on their side. Enter your IPv4 address and enable the tunnel. On your machine, add the following to /etc/rc.conf: ...

Win drivers under freebsd Sagem SA XG703 USB 802.11g

moods — Sat, 17 Jun 2006 02:04:00 GMT

The NDISulator is an invention of Bill Paul (wpaul at ) that allows you to use Windows network drivers under . Here's a few steps that should get you going with it.

1. cvsup to the latest -CURRENT. The NDISulator isn't available under 4.x.

2. Install the base NDIS code. cd /sys/modules/ndis; make; make install

3. Locate a Win2K/XP driver for your card. The driver should include a SYS and an INF file, usually in a directory called WIN2K or WINXP, but they could be hidden somewhere else. For my Linksys card, it was bcmwl5.sys and lsbcmnds.inf.

4. cd /sys/modules/if_ndis

5. cp /wherever/.../sysfile.sys .; cp /wherever/.../inffile.inf .

6. ndiscvt -i inffile.inf -s sysfile.sys -o ndis_driver_data.h

7. make; make install

8. kldload ndis; kldload if_ndis

9. ifconfig ndis0 (standard ifconfig arguments) For my Linksys, this was ifconfig ndis0 inet 192.168.0.3 ssid etcetc channel 11 wepmode on wepkey 0x12345(etc.)
