Hello Jim,
I download and try the new ldm version, but autologin does no work.
I saw the code and see that ldm get info from lts.conf
I lts.conf i put
[00:44:00..]
LDM_USERNAME = wk1
LDM_PASSWORD = pass1
but does not work.
do you have any suggestions?
thanks a lot

Faraz,
password aging is currently being added to LDM. In fact, LDM has been
completely rewritten in C, so it's much faster than the python version.
Not because python is necessarily slow, but because it's so slow to
load the python interpreter and libraries across the NFS root filesystem.

Just a comment regarding LDM - for slightly larger 'corporate' setups we
would need forceful password changes, password aging, etc. SSH correctly
handles these (through PAM or Kerberos) but LDM does not. I know this
may be low priority- but is there a wish list i can add this to? this
really prevents me from implementing LDM at slightly 'corporate'
locations. I thought of doing this myself but really see no way this can
be easily done (unless the thin client does a PAM authenticate first and
then ssh)

Anthony-
ssh is still used as a communication tunnel between client and server.
For example, it is used to launch the session, set up sound, trigger
mounting of local devices, that sort of thing. The only difference is
that you are not proxying the ssh traffic through ssh, so you eliminate
I think he meant "not proxying the X traffic through ssh"
Jim.
the overhead of encrypting the video data (the majority of the ssh
overhead in the secure scenario) and, more importantly for performance,
you are not proxying the X traffic, but rather directly talking between
the applications and the xserver.

I apologize. I tried it again, this time with a fresh setup, and
everything worked perfectly. I must have setup things incorrectly on
the first attempt because your modified LDM script works beautifully.
I am curious, is it just X that's no longer being encrypted over ssh
with the new LDM_DIRECTX option or is the entire terminal session no
longer using ssh, because I noticed that sshd is still a running
process.

Anthony,
In LTSP5, gdm is not used at all. You need not enable XDMCP in gdm or
even have gdm installed on the server. If enabling it changed things,
that must mean you have SCREEN_07=startx in your lts.conf. Don't do
that. Take it out. Use ldm. Then, you localdev and everything else
should work.

I gave this version of LDM a whirl and was pleasantly surprised. It
does boot quicker and, after configuring GDM for remote logins, I was
quickly presented with a login screen. Sound still works, but I notice
that the USE_XFS and LOCALDEV options in the lts.conf file do not have
an effect. Local devices aren't critical, but I need access to the XFS
server since we use IBM's iSeries Access that requires un/scalable
fonts.
Am I doing something wrong?

Hello all, I met with Gideon Romm at our North Central Linux Symposium. He has been
working on modifications to the code for ldm to allow the bypass of X being encrypted
over ssh. He has also added functionality to be able to use autologin. You can
download the modified ldm from here:
http://codebrowse.launchpad.net/~gideon/ltsp/gadi-ldm-mods-ltsp/download/gadi%40ltsp.org-20070521205254-ek710bofdpdtlwlz/x_Matt_Zimmerman_%3Cmatt.zimmerman%40canonical.com%3E_Tue_Jun__7_19%3A59%3A49_2005_32192.0/ldm
Replace your current "/opt/ltsp/i386/usr/sbin/ldm" with the new file (you may want to
backup your current ldm just to be safe). The in "/opt/ltsp/i386/etc/lts.conf" add the
following line:
LDM_DIRECTX=True
You will now be able to run without X being encrypted, which in theory should allow LTSP
5 to run at the same speed as LTSP 4.2. Bootup times and logout times will still be
slower, but once booted things should zoom along. So far my tests show that this works
awesome! I am still waiting for my new clients to really give this a go.
If you would like to use autologin features you simply need to add the following line to
lts.conf:
LDM_USERNAME=hostname
Apparently this lets you use the same user=workstation method that worked in LTSP 4.2.
You will still need to setup ssh keys OR create the same password for each user and
specify LDM_PASSWORD="mypassword" (in lts.conf). You also need to specify workstation
names in dhcpd.conf so that workstations do not all have the same hostname (I am not
sure if this is able to be done with the /etc/hosts file as well).
Anyhow this hacked ldm should allow LTSP 5 to finally be usable in larger installations
instead of hanging on to LTSP 4.2. Also I guess that Scott Balneaves has rewritten some
of the python startup files in C, which should clear up some boot time problems in the
next Gutsy release (Scott, sorry if I butchered up what exactly you have been working on).
