According to this http://thunar.xfce.org/news.html#2007-01-21 Thunar suppose to support "trashing to top directories" since version 0.8.0! So could it be something in the specific implementation that do not show removables as such?

It may be specific to FAT filesystem (it does not support permissions). I should check...

Teapot, on my home Windows XP PC, I run the WatchGuard Firebox SSL client (powered by Citrix).  This gives me a login for my ID and a 10-digit password, the last six of which dynamically change with my RSA SecurID.  The client indicates I am connecting to ra.*******.com:443 at a DNS server address of 210.***.**.*** (the WINS server address listed is the same).  There is a second DNS server listed with address 10.*.*.*.  The client indicates that split DNS is enabled.

Oh, it's Firebox Citrix-only "SSL VPN". You are screwed as far as true VPN functionality is concerned. How nice it was of them to make their device around a Linux embedded system, and in return turn it into a perfect tool for preventing people from using Linux to do their work.

Ask IT people at work to add some other kind of VPN -- PPTP, IPSec or OpenVPN. Those are open protocols supported on all platforms.

That all said, can you help me properly configure the Citrix ICA/Presentation Server/XenApp client based on the server data above?  I assume you have the client now on your XO, else you'd not have seen the awful OpenMotif presentation.  For example, a new connection requires selecting a network protocol of TCP/IP, TCP/IP + HTTP server location or SSL/TLS +  HTTPS server location.  There are other choices to be made in different tabs.  The goal would be a remote desktop presentation, replicating what I can do off my home PC connecting directly to my office.

Apparently, WatchGuard has two approaches for access to the Firefox SSL core.  From their site:

Q: How can applications and network resources be accessed using the Firebox SSL Core?
A: Firebox SSL Core provides two powerful modes of access out of the box:

    * Secure Access client mode utilizes a Web-deployed, auto-updated client that enables access to applications and information resources in their native interface over an SSL-encrypted tunnel.
    * Kiosk mode offers one-click access from Microsoft® Windows® and Java™-enabled Web browsers to Web-based applications, an integrated Citrix® ICA client, Remote Desktop, SSH, Telnet 3270 emulator, VNC servers, and shared network drives over an SSL-encrypted tunnel.

Q: What devices can be used to access the Firebox SSL Core?
A: When accessing the network using Secure Access client mode, devices must be running Windows 2000, Windows 2000 Professional, Windows 2000 Server, Windows XP, XP Home, XP Professional, and all Linux 2.4 platforms.

When accessing the network using Kiosk mode, devices must be running a Windows browser or Java-enabled browser (JVM v1.4.2 or higher).

Try to access it from a browser in the "kiosk mode" (it may be disabled, so ask a sysadmin at work to enable it and to give you a URL for it), and see what it actually supports -- it may provide remote desktop or even ssh server that you can use to tunnel your connections.

Okay, I'm foolish thanks to both of you for your patience. I was in fact downloading the torrent on an XP desktop using utorrent. I did not know I should extract the full file on that. I have 7zip, have extracted the file, and put it on a usb again but now am when trying to unpack it onto the sd card I get a no such file or directory error. After using 7zip did i need to change the terminal command from 'tar xvjf' or change the file designation or something?

Tried 7zip again this time I got an error that read:
bzip2: (stdin) is not a bzip2 file

Did I extract it wrong?

DON'T extract anything on Windows -- tarball has to be extracted to ext3 filesystem with all attributes preserved. Once you have downloaded the tarball, copy it to a USB drive.

[teapot]

If the cards where unmounted properly (and I think they may have even with the signal 15 error), no.
Try them! Should not harm the XO anyway.

No, it still doesn't boot into Ubuntu. I can see and browse the sd card under media/OLCRoot/ and everything looks ok. Here is my  boot screen.

You have a developer key, but it's not for your XO.

Ok. Then I have no idea why this won't work. That is exactly what I did in the first place. Going on I think 5 attempts now. Downloaded on an XP machine using utorrent(with integrity good). Copied straight to a Memorex USB, erasing partition and making the new partition goes smoothly, then I try to unpack to my sd (a class 4 PNY 4gb) but it always fails with this error:
tar: Skipping to next header

bzip2: Data integrity error when decompressing
           Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the 'bzip2recover' program to attempt to recover
data from undamages sections of corrupt files.

tar: Child returned status 2
tar: Error exit delayed from previous errors

[teapot]

It is possible that the compressed file(s) have become corrupted.

Download the file again.

It gets better.  The IT people told me yesterday that Citrix and WatchGuard are in some sort of fight with each other and Citrix has withdrawn continuing support to WatchGuard on the Firebox product.  Worse, we have home users with Vista on their PCs and the Citrix VPN client won't work with Vista, either.  So, apparently our IT folks will be selecting a new VPN system in the foreseeable (although unfortunately not overnight) future.

I don't think I'll succeed in getting our IT staff to create or open another VPN in the in-between time just for me and my little Linux experimentation.  They have other, more important fish to fry.  

They don't recommend that I try to set up a home VPN without security expertise, thinking that I'll leave my home PC accidentally exposed to the world.  Perhaps you think setting up a home VPN on a Windows PC that would be accessible easily by the XO is not a daunting task.  If so and you are in a teaching mode, I'm game.

Oh, yes, the Citrix "kiosk" mode.  Well, our IT folks have only three tunnels for this and reserve them for emergencies, so they don't want to open one for my general use.  On top of it, they say that it provides only limited functionality (no full VPN and the keyboard apparently doesn't work well).

Thank you, Citrix.

Do you think there's any way to improve the gotomypc situation -- such as (if it exists) a USB video card compatible wth Linux that would take the load off the XO's internal processor or a different third party VPN that doesn't run using a Java applet -- or are you up to becoming a home VPN instructor?  Thanks.  JCR

---------------------------------------------------

Total aside -- I wanted to change the wallpaper on my XO to put up a favorite photo.  I did this by saving the photo in jpg format to /usr/share/wallpapers.  This must be a secure folder under Ubuntu.  I had to access that folder by running terminal, sudo thunar.  Once saving the photo in that folder, I changed the wallpaper under the Desktop settings using the installed Xfce settings manager.

I am not sure if they want my advice, but it remains the same -- anything that supports either of widely used open protocols. OpenVPN does more or less the same thing as Citrix VPN -- SSL-based VPN with various kinds of authentication -- except it's open source, and it supports, among other systems, Windows Vista and Linux.

I don't think I'll succeed in getting our IT staff to create or open another VPN in the in-between time just for me and my little Linux experimentation.  They have other, more important fish to fry.  

But they might do it for you plus Vista-using people.

They don't recommend that I try to set up a home VPN without security expertise, thinking that I'll leave my home PC accidentally exposed to the world.  Perhaps you think setting up a home VPN on a Windows PC that would be accessible easily by the XO is not a daunting task.  If so and you are in a teaching mode, I'm game.

You still have to have _something_ visible from outside, and your home PC is on a private address, so I don't know how it can be helpful. If you can move home PC to a public IP address, you can try to use it for relaying packets between OpenVPN and Citrix VPN.

Do you think there's any way to improve the gotomypc situation -- such as (if it exists) a USB video card compatible wth Linux that would take the load off the XO's internal processor

That won't help at all -- USB video card is slower and has less accelerated functionality than internal one, and CPU will still have to run the same slow applet.

or a different third party VPN that doesn't run using a Java applet -- or are you up to becoming a home VPN instructor?

If IT people at your work can configure OpenVPN, PPTP or IPSec firewall, or SSH server visible from outside, you can use them to run VNC or rdesktop.

Total aside -- I wanted to change the wallpaper on my XO to put up a favorite photo.  I did this by saving the photo in jpg format to /usr/share/wallpapers.  This must be a secure folder under Ubuntu.  I had to access that folder by running terminal, sudo thunar.

Files used in default configuration are supposed to require root (or some other administrative account) access for writing -- otherwise on a multiuser system users would be able to change each other's configuration.

Once saving the photo in that folder, I changed the wallpaper under the Desktop settings using the installed Xfce settings manager.

You could also put the image in some directory under your home -- wallpaper doesn't have to be in the same directory as the default image.

For the last ubuntu image (hardy) i was able to apply some hack in order to install better video drivers. This broght up the frame rate from 30fps to 60fps (80 when overcloced) using glxgears. Is this driver allredy included in this Image of Iterpid ?
I'm asking because with glxgears I'm getting just the 30fps. However I'm not sure if this means anything or if this would be of any bennefit in my normal usage.

I am trying to use distribution's native packages whenever possible, so since "geode" driver included with Intrepid supports XO, and I didn't notice any slowdown under normal use, I included it and updated X to use it. I never tried to run any 3D applications on it -- my main "benchmark" is mplayer.

I guess, there is some regression between configuration used in Hardy and current version, however I still don't know if it applies to 3D support (OpenGL) or acceleration in general. I will rebuild relevant packages and see what exactly was changed between those versions.

I followed the instructions to install Ubuntu to my 2GB sd card and everything went fine.  I went to type in the command "touch mnt/etc/xo-suspend/aggressive" to enable aggressive power saving mode and I got an error; something like cannot touch no such file.  At the time I didn't write it down so I don't remember exactly what it said.  I rebooted my XO and it boots fine into Ubuntu but I was wondering if there is a way I can enable the aggressive power saving mode after already installing Ubuntu?

I forgot slash before mnt (sorry for that -- fixed now).

However as mentioned earlier  in the same message, sudo touch /etc/xo-suspend/aggressive and rebooting will enable that mode, sudo rm /etc/xo-suspend/aggressive will disable it (I should finish and post a configuration utility for power management options and modes).

I have now installed my own intrepid on an 8GB SD card after setting up one for my sister.  Thanks again to Teapot for such a great package and to mavrothal for his "index to soultions"  His link to "dpkg --get-selections | grep -v deinstall" helped me to make sure I had the same software set up on intrepid as on hardy (although I did it manually rather than automatically to avoid version conflicts)

But I am having one big problem: It is PAINFULLY SLOW!  I am using an HP 8GB type 4 (4MB/s) SD card and I have the aggressive power-savings turned on.  It was slow before I even installed a ton of software.

Is it particularly slow on this card? Did you have Hardy installed on the same card before? what processes are running (output of ps axuw ) ?

no it is a different card from my Hardy install since I did not want to wipe that until I had Intrepid working well.

no it is a different card from my Hardy install since I did not want to wipe that until I had Intrepid working well.

the output of ps axuw is

I don't see anything unusual, so maybe it's something with a card... Try to wipe and reinstall it, and if nothing changes, try another card -- all I know is that some models work poorly with XO. Sandisk seems to cause most complaints, however Sandisk Ultra II 4G dual-interface USB/SD seems to work fine on my XO.
