Re: [Ltsp-discuss] error open file from network using localapps

[lpadumorvan]

Hi

why no username and a password is present ?

Try this in fstab

Change noperm for : file_mode=0777,dir_mode=0777 ? Can you create a new 
directory or new file from a thinclient session in the network share ?


Also try :

del credentials = / home /teste.txt and replace with username="toto"; 
password="pwd of toto"


and add dom="your domain"

Also try :

in mnt create directory myshare

change rights of myshare : chmod -R 777 myshare

in fstab: change /mnt for /mnt/myshare (in //10.21.8.2/departamentos 
 / mnt .)

The problem that when the user opens the folder the same is empty, 
however if I put the User genadmin only without the credentials it 
opens everything and can change the files.


My question is, as I cosigo mount folders of users however observing 
the active directory permissions, what better way?



Thank you so much again

Hi

How is mounted the network share on the ltsp server ? in fstab or
with pam_mount ? What is the file system of network share ? nfs, smb ?
File permission are open/write but for which user ? For the user
of the session ?
Do not confuse the rights of the network share and the rights of
the mountpoint !

You'll at least need the "debootstrap" package from
jessie-backports. Older versions of debootstrap do not support xenial.

1) Yes.
Note also that there is a FAT_RAM_THRESHOLD variable, which defaults to 300.
If a client has more than 300 MB RAM, it's automatically fat.
If it has less than 300 MB, it's automatically thin.
LTSP_FAT_CLIENT=True/False overrides FAT_RAM_THRESHOLD.

Only chroots that have a desktop session (files in 
/usr/share/xsessions/*.desktop) support both thin and fat clients. 
ltsp-pnp supports both.

2) Yes.


Btw, someone here in this topic mentioned that a use case for thin 
clients is when you want to run math software on a beefy server.
I'd like to add that it's very easy to use fat clients in this case, and 
run that math app with LTSP *remoteapps*, which run on the server.

So, thin clients can have localapps that run on the client,
and fat clients can have remoteapps that run on the server.

Hello

I have setup a xenial ltsp pnp server.

Is LTSP_FAT_CLIENT=True/False the only config needed in lts.conf to switch ?

Is ldm mandatory for fat client ?

Thank you.

Yes, I guess I will try both setups first. Now I am running quite old

Our needs aren't so ambitious ;) We just need a solid "office
