[Ltsp-discuss] mirror LTSP-Server

[Frank Heuser]

Hello,
I'm new to this list, but using LTSP for 6 years with rare problems.

No my company evolves and a new building must be integrated to the it
infrastructure. There is a fast DSL-connection. At side A 109.3 Mbit/s
download 42.0 Mbit/s upload and at side B 55.0 Mbit/s download 10.0
Mbit/s upload. ping time lower 30 ms.

The routers are Fritzbox 7490 with activated VPN.

My experience is that tftp is very slow (about 15kB/s; scp-speed is
about 1.1MB/s) because of the latency I guess. So the booting needs
about 8:30 minutes. That doesn't satisfy.

So my question:
Is it possible to connect to the LTSP-Server (at side A) with a Computer
at side B with Linux installed and ldm. How to configure ldm? Would it
work, or is the latency also a problem for this constellation.

Other solution I'm thinking about is to install at side B a second
LTSP-Server. But there is the question how to mirror data, user
information and applications. Is there a known solution for this?

Thank you!

Regards
Frank Heuser

Hi André,
thank you for your hint. This cluster solution seems to be a bit complex.
And as I see, there is just a load balancing in terms of a random
assignment.
I would need a assignment of a particular clients to a particular server.

I tested to use XDMCP over DSL. It works, but no fun. (Waiting 5 seconds
on opening a menu.)
So X over DSL is not a solution.

Next try is to install X2go-Server on the LTSP-Server and on the client
a standard xubuntu with X2go-Client.

I would appreciate further suggestions.

Best regards

Hi,
Do you knowhttps://www.ltsp-cluster.org?
I am not a consultant, just an interested end-user. May be the question
can be : Is there a way to have a cluster over a VPN? Then the second
optimisation could be to force some client on specified (in your LAN)
server. By doing it this way the only traffic over VPN would be for
user identification.
This is the way I would take my first approche to this kind of solution.
