[Ltsp-discuss] Reference for lts.conf and dhcpd.conf

2007-07-20 Thread Fajar Priyanto
Hello,
I once have a short encounter with LTSP 4.0 2-3 years ago. Very impressive. 
Now comes opportunity to me to implement LTSP 5. I use ubuntu Feisty 7.04 and 
the level of integration is fascinating. Bravo to LTSP and Ubuntu team.

However, I notice that the default lts.conf is now without any 
comment/example? Also the dhcpd.conf. Where can I get any reference/url for 
lts.conf and dhcpd.conf for LTSP 5? All I've found so far from google is for 
LTSP 4.x.

Thank you very much,

 Hi

 Session Persistence seems to be good point in favour
 of NX.

 Is there anyway in ltsp providing such facility?.
   
People have reported getting NX to work on LTSP clients. 
It does seem to take about 35 more seconds to resume a connection with NX.
VNCServer can be rigged to offer the same sort of session persistence.
There are lots of tools out there  for different jobs.

Well, the dhcpd.conf hasn't changed all that much.  It's pretty well
documented in man(1) dhcpd.conf.

As for the lts.conf, check out the Edubuntu handbook, which has the most
up-to-date info on lts.conf:

[Ltsp-discuss] LTSP5 and Dynamic DNS

2007-07-20 Thread Fajar Priyanto
Hello guys,
I have a running LTSP5 on Feisty. Yesterday, I experimented on setting up 
Dynamic DNS update by the DHCP. It works! :) I tested by booting up my 
non-LTSP client, and the DNS record got updated by DHCP.
However, not so successful with LTSP client.
The LTSP client got bootup, searching for DHCP, got IP, running TFTP, and got 
time out finding the TFTP server.

I think I've got an obvious mistake, but I cannot figure it out yet. Googling 
hasn't yield any solution.

Has anyone got Dynamic DNS with LTSP? Any clue/url will be great.

This is my dhcpd.conf (I use the standard one from LTSP5 and then adding some 
lines at the top):
authoritative;
server-identifier   acerubuntu;
ddns-updateson;
ddns-update-style   interim;
ddns-domainname pluto.com.;
ddns-rev-domainname in-addr.arpa.;
ignore  client-updates;

include /etc/bind/rndc-remote.key;

zone pluto.com. {
primary 10.0.0.17;
key rndc-remote;
}


subnet 10.0.0.0 netmask 255.255.255.0 {
  range 10.0.0.50 10.0.0.60;
  option domain-name pluto.com;
  option domain-name-servers 10.0.0.17;
  option broadcast-address 10.0.0.255;
  option routers 10.0.0.254; 
  option subnet-mask 255.255.255.0;
  if substring( option vendor-class-identifier, 0, 9 ) = PXEClient {
filename /ltsp/i386/pxelinux.0;
  }
  else{
filename /ltsp/i386/nbi.img;
  }
  option root-path /opt/ltsp/i386;
}



And my named.conf:
acl rndc-users {
 10.0.0.29/32;
};

key rndc-remote {
 algorithm hmac-md5;
 secret FCB7+bECYF2Gs//nFPxhBA==;
};

key rndc-key {
  algorithm hmac-md5;
  secret qAmZciCbn3CrGIMN2IeDxg==;
};

controls {
 inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { rndc-key; };
 inet 10.0.0.17 allow { rndc-users; } keys { rndc-remote; };
};


zone pluto.com {
type master;
file /etc/bind/zones/pluto.com.db;
allow-update { key rndc-remote; };
};
zone 17.0.0.10.in-addr.arpa {
type master;
file /etc/bind/zones/17.0.0.10.in-addr.arpa;
allow-update { key rndc-remote; };
};

Thank you very much.

Which tftp server? tftp-hpa is one you should be running.

DynDNS is for upside IP / Name assignment. DHCP is for downside. (To
speak in LTSP overview)

I have servers which get name / ip assignment from DynDNS but dhcpd
does not come in to picture here. And they server clients under LTSP.

[Ltsp-discuss] How to prevent user from shutting down the server?

2007-07-20 Thread Fajar Priyanto
Hi all,
When a user click on the Log off button, then click Shutdown, the LTSP5 
server got shutdown! How do I prevent this? Is it a normal behaviour?
I'm using LTSP5 on Feisty.

Hello Sudev,
Sorry for confusing you with the term.
What I mean by Dynamic DNS is that we can set DHCP server to update the DNS 
record dynamically.

So, when I boot a client, it will get an IP address from DHCP server, and then 
DHCP server will contact the DNS server in our network to update the A and 
PTR record in DNS server for the just booted client.
Cheers.

I can only see this as being useful if the hostname is then static, is this the 
intention? Otherwise the standard way of using the /etc/hosts file is more 
useful, which is to set a hostname for each allocated IP address.

On the contrary, by using dynamically updated DNS server from DHCP, we don't 
need to maintain the ip - hostname, and hostname - ip tables anymore. The 
DNS and DHCP will work together to provide hostname and ip resolution.

It's still interesting though, to know whether the scenario is possible for 
LTSP setup.

Re: [Ltsp-discuss] How to prevent user from shutting down the server?

2007-07-20 Thread José Queiroz
Hi Fajar,

If you do use KDE, you can enter KControl, option System
Administration, then Login Manager, Admin Mode.

Open Shutdown tab, and in field Allow Shutdown/Local, choose Only root.

[The option names may be different, as my KDE isn't in english]

There must be a similar setting on gnome, also.
