Do an lshw -C network on one of the problem children and let me know what it says the wireless card is.

If you want to make ncp-ip mounts against Novell servers, install ncpfs using Synaptic, or sudo apt-get install ncpfs

Such utilities are usually built into the BIOS on those devices. They are also generally useless for solving problems, IMHO

Hardware Specific / Re: Acer AspireOne 722 - AMD suspend issues
« on: April 16, 2012, 09:58:46 AM »
I've seen this on similar models with the VA-API installed - have you tried redoing the driver install and answering "no" to that option? Be sure to start from a fresh ubermix install, otherwise the original VA-API software won't go away.
Unfortunately, AMD hasn't been very consistent with the "C" and "E" series chips. We've seen several different underlying versions, which has been causing some trouble with reliability and drivers.

Q&A / Re: directory authentication

Ronald Stoddard just posted a page in the ubermix wiki explaining how to authenticate to AD using CentrifyDN
http://wiki.ubermix.org/page/Adding_Ubermix_to_Active_Directory_using_CentrifyDN
Note: If you are using a recent 0.9x version of ubermix, you shouldn't have to do any of the hostname-update changes listed on the page - the auto update script has been fixed as of v0.911.

Q&A / Re: directory authentication
« on: April 09, 2012, 09:27:42 AM »
Don't know why I didn't think of this before: One of the main reasons most people want to authenticate ubermix to a "network infrastructure" is because they are deploying it is a "shared use" setting - like a lab or mobile cart - where each device might be used by several people. In such an environment, a user's ability to customize the machine might not be what you want, as the following user might be confused by the customizations of a prior user. While authenticating each user is certainly one way to solve the problem, a simpler way is to set the devices to auto-reset at startup, thus guaranteeing the default "look" every time. This only costs about 30 seconds of startup time (depending on the speed of your hard drives, of course), so it's really a no-brainer for most shared use applications.

Development and Scripting / Re: Network File Storage
« on: April 04, 2012, 09:07:35 AM »
A couple thoughts: It seems the easiest way to make this work would be to create a bookmark in the file manager (nautilus). To do that:
If you want to stay on your path, then there are a few other possibilities (one of which should work):
Hope this helps!
- Open any folder
- Go to File->Connect to Server
- Enter all of the credentials and check the "Add Bookmark" and give it a sensible name, like "Server"
- When prompted for a password, choose "Remember forever"
If you want to stay on your path, then there are a few other possibilities (one of which should work):
- Add your umount script to /etc/network/if-down.d in the same fashion as you did up (might work)
- Create a .bash_logout script in the home folder with your logout command (be sure to make it executable).
- Add the command to /etc/gdm/PostSession/Default
Hope this helps!

Q&A / Re: directory authentication
« on: March 31, 2012, 11:24:08 AM »
Directory authentication is definitely do-able with all of the directories you mention, however the limitations and complexities of being tethered to a directory typically outweigh the benefits with mobile devices. For Active directory, there are both free and commercial solutions, as you might expect. OpenLDAP (which we use for all of our servers) is free, of course, and Novell obviously supports Linux authentication to eDirectory (they are a Linux provider, after all). I've authenticated Linux clients using all three mechanisms, and generally believe that the costs outweigh the benefits.
AD/Windows Authentication
I've personally used winbind authentication, which is probably the quickest and easiest path, against AD and Samba servers running on Linux successfully. You can read about getting that set up at https://help.ubuntu.com/community/ActiveDirectoryWinbindHowto. If you want to go after full Kerberos SSO and the like, there is documentation at https://help.ubuntu.com/community/ActiveDirectoryHowto. Once you start to head down that path, the commercial solutions, like Centrify and Likewise will definitely be worth a look.
LDAP
LDAP authentication is part of Linux's DNA, so getting set up for this is fairly straightforward. Basic LDAP authentication can be accomplished with the ldap-auth-config and ldap-auth-client packages - see https://help.ubuntu.com/community/LDAPClientAuthentication for details. Of course, you'll need to have a properly configured LDAP server at your disposal, which can technically be any LDAP compliant server with the right schema extensions. OpenLDAP is free, of course - you can learn about setting it up at https://help.ubuntu.com/community/OpenLDAPServer. Oreilly also has a really good book titled LDAP System Administration, which was something of an LDAP bible for me when I was first getting started. Using a MacOSX server (which uses OpenLDAP for it's directory) might also be an easy way manage an OpenLDAP server for your Linux clients, although I haven't looked into it personally.
eDirectory
Good luck on that one. I did it once about a decade ago when Novell first got into Linux using a solution similar to the one posted at http://www.novell.com/coolsolutions/feature/5706.html, but haven't looked since. I know they have some sort of extended client, which they talk about here: http://www.novell.com/products/clients/. I've heard bad things about trying to get the client to work on anything but SuSE, so you'll probably be better off sticking with a stock LDAP authentication. I would try a combination of the instructions in the Cool Solutions link above and the Ubuntu LDAP authentication link in the LDAP section above.

General Support / Re: Change the color of the top bar/panel
« on: March 27, 2012, 02:59:52 PM »
Unfortunately, it's not something that is in the generic settings for appearance, you have to change it in gconf-editor or the command line. I'm going to make it semi-transparent in the next release so that it won't clash with anything, but in the mean time you can open a terminal (ctrl-alt-t) and type gconf-editor, then navigate to /apps/panel/toplevels/top_panel_screen0/background/color and change it there. To select a color, use the GIMP to either pick a color using the color selection tool or use the eyedropper tool on a portion of your background image to select a color, then copy and paste the value in HTML notation to the /apps/panel/toplevels/top_panel_screen0/background/color field. Be sure to precede your color with a "#".
If you're feeling adventurous, you can do this even faster from the command line with:
(replace "#0055a3" with the color of your choosing)

General Support / Re: Updating Browsers and Java
« on: March 27, 2012, 09:47:17 AM »
I assume you are attempting to update the browser on the base system partition, correct? If so, I would recommend increasing the size of the base system partition, so that you have a little more room to maneuver. To do this, boot from a current ubermix install key, choose option 5 (Expert) followed by option 3 (Resize) and set your base to 5 gig (which should be plenty). Then apply your updates.
