Boot time was the same, login was faster.

Speed - Lenny vs Squeeze

Ole-Anders Andreassen — 2012-05-25T09:47:27

Hi!

I have used Squeeze a week now, and there are a lot of things to like. 
But what I don't like, is that Squeeze seems to be slower. Booting is 
slower, logging in takes longer time, and starting programs also takes 
longer time.

I am using the same server hardware on both installations, same network, 
same clients...

Anyone with the same experience?

Hi Maurizio,

I added a server 2008r2 just the other day. It should not be much difference to add a Windows 7 workstation. I will have to try that soon ;)

I first activated the administrator in samba (on tjener);
sudo smbpasswd -e Administrator

Then I downloaded the .reg file that you will find on tjener in 
/etc/samba/netlogon/win7+samba_domain-membership/Win7_Samba3DomainMember.reg to the server and imported it into register. (right click and merge)

Of course, if you have a server, you will have to downgrade it first so it does not act as a pdc it self. That is not an issue with a workstation.

Then just right-click My Computer -> Preferences -> Advanced
In tab Name you click Change and fill in SKOLELINUX

I have not tried XP with Squeeze.

Maybe I missunderstand you?

Please file a bugreport against freerdp to raise awareness of this issue

If you want to include this list in the conversation at that bugreport,

Single sign on to windows?

George — 2012-05-24T07:37:22

Hi,

I tried to find out how to setup single sign on from a skolelinux client to a server 2008r2

We have some few (especially InDesign) windows programs we need to run, so unfortunatley I can't get rid of windows..

What I want to do is to create an application starter for the windows program that starts a rdesktop session for the skolelinux user.

Are there any way to get single sign on to work between skolelinux and server 2008r2? 
The server are joined to the skolelinux domain, and rdesktop session works (somewhat, I have an issue with shelling into a program instead of starting the desktop, but I guess thats a windows issue.)

When googling around there are many guides for single sign on but they require a windows pdc with active directory, and in this setup its the tjener that works as a pdc.

Does it require more ldap integration between the server 2008 and skolelinux, than samba already gives me?

Anyone that has done this?

Sunny greetings   /George

Because there is a mecahnisme in cups that does all this automatically

I don't have a debian-edu squeeze installation handy, what does this

grep -i browse /etc/cups/cupsd.conf

That is where I would start to look.

I see that it is configurable where the printers are announced. Could it 
be the case that only the thin client network is set up to get the 
broadcasts?

There was another user having the same problem just now, so I suspect 
this might be a bug or regression since earlier versions (or few used 
diskless workstations before).

We maybe should also set the environment variable CUPS_SERVER to point 
to the print server.

Diskless and Kerberos

Giorgio Pioda — 2012-05-23T07:26:33

Hi,

last night I got a half a cent idea for Diskless stations Kerberization.

What about exporting the chroot / file sistem containing a single /etc/krb5.keytab
containing all the nfs/disklessclients entries...

The single diskless unit should get its hostname via dhcp (assigned from MAC)
and then could pick the correct TGT key and preauthenticate.

The only problem would be to play a little with the boot sequence, so that
Kerberos TGT challenge will happen with correct timing.

The basic Idea is thus to protect exported homedirs and leave the rest as
cleartext filesystem.

Probably I was too tired and this idea is just bull****. At the moment
I have no testing time / hardware.

Best Regards

Giorgio

Do you know if the printers are also missing from standalone workstations?

I guess the diskless workstations needs a config that says it can use 
the server as printer server, and it works with the thin clients since 
the print server is local.

Install flashblock to avoid the ad resource waste.

It would probably be a better default to not install Gnash.

I sure hope neither you nor Ole Anders teach mathematics.  Given that
working Youtube is more than 0% useful, and gnash work with youtube,
gnash can not be 100% useless.  If working Youtube is 1% useful, gnash
can at most be 99% useless.  If you calculate this and reach 100%, I
believe something most be wrong with the calculator.


 1) Not include Gnash, and make youtube and all other Flash pages fail
    to work completely after a fresh installation.
 2) Include Gnash and get working Youtube and a small fraction of
    Flash web pages work after a fresh installation.

Note that the adverticed option is out of reach for us, due to
copyright and patent issues:

 3) Install flashplugin-nonfree and get most Flash pages workout after
    a fresh installation.

What would you propose we do?  Go with option 1 or 2?

Re: Gnash != useless

Nigel Barker — 2012-05-21T02:51:56

Flash is essential here. So many primary school activities include it.
Many activities (eg. on BBC kids) need flash>10, and don't work with
Gnash.

Gnash work with youtube and older flash content (ie AVM1, not
AVM2).  So it is not 100% useless.

Flash on the other hand is 99% useless, so it is better to avoid
pages requiring Flash and use any alternative there is.


It is normal that more pages work with flashplugin-nonfree, as it
support the newer format AVM2.  Unfortunately Adobe have dropped the
Linux plugin working with most browsers, so it will not keep working. :(

If we want Flash to keep working, we need to switch to Chrome, or fund
more free flash (Gnash/Lightspark) work.
