<bintut>
i want to centralize a dhcp3 server into one.. the network is using class b (172.16.0.0/16) that has standalone workstations using windows and linux and ltsp thin clients using pxe and etherboot.. i also want to assign a range of ip addresses that from 172.16.11.0 to 172.16.100.255 will be used by the ltsp thin clients both using pxe and etherboot and from 172.16.101.0 to 172.16.255.254 will be used by any standalone or fat workstations..
02:10
the network is not that big enough... maybe around 300 to 350 hosts only but we decided to use class b for future expansions..
02:11
now my problem is, how can i group them in such a way that i can identify or the dhcp3 server can identify the range of ip addresses?
02:13
first, for the ip range from 172.16.11.0 to 172.16.100.255 to deny other workstations to use the ip addresses because it is allocated for ltsp thin clients and to automatically choose from pxe or etherboot..
02:15
second, the ip range from 172.16.101.0 to 172.16.255.254 will be given to standalone or fat workstations and will not download the linux images for pxe and etherboot..
02:15
any tips you can give?

Something like this:
03:07
if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
03:07
filename "lts/eb-5.4.2-eepro100.zpxe";
03:07
} else if substring (option vendor-class-identifier, 0, 9) = "Etherboot"
03:07
{
03:07
filename "/lts/vmlinuz-2.6.17.3-ltsp-1";
03:07
option vendor-encapsulated-options 3c:09:45:74:68:65:72:62:6f:6f
03:07
:74:ff;
03:07
}
03:07
bintut: In a range declaration.

<bintut>
Patina: sorry for the late reply..
03:32
Patina: what about those standalone or fat workstations? they might download the kernel from tftp..? or it won't?
03:33
<Patina>
bintut: They will not match the substring
03:37
<bintut>
Patina: oh.. if that's the case, the first problem has been answered already.. what about reserving a range of ip addresses for ltsp and separate for standalone/fat workstations
04:02
<Patina>
Two subnet declarations: subnet 172.16.101.0 netmask 255.255.255.0 {
04:03
range 172.16.101.0 172.16.255.254
04:03
....
04:03
}
04:03
And another also containing the substring testing
04:05
<bintut>
Patina: isn't it that a netmask of 255.255.255.0 has 254 usable hosts only?
04:06
Patina: what is the netmask for the ip range of 172.16.0.0 to 172.16.10.255?
04:06
<Patina>
bintut: Thats sounds correct, if you create two subnets with different addresses and that netmask, you will have 508.
04:07
bintut: You will have to calculate that one yourself.
04:08
<bintut>
Patina: also, what is the netmask for the ip range of 172.16.11.0 to 172.16.100.255? and from 172.16.102.0 to 172.16.255.255?
04:10
Patina: ok
04:18
Patina: can i have multiple subnets inside a shared-network? for example, consider this:

I really don't know how shared networks work.

<mascote>
I use Red Hat Enterprise 4.0, and download from fuse project the tarball, I did the ./configure, make e make install.
06:48
The /dev/fuse is installed, but it is rw------- and the owner is 'root' and the group-owner is 'root' too. I change it to group-owner to 'fuse' group, but it's returned to group-owner 'root' again !
06:48
Anyone can help me? Thanks.

Hi all, in the past few days, I've setup a ltsp server and a client image. I'm really pleased with how well it works. But still, there a a few thing: I always get the KDE crash handler when exiting a session, is this known behavior?

Hi sbalneav, how cold is weather up there?

Not cold at all at the moment. 3C right now, above freezing!

Hello everybody! I'm looking for help to solve a problem I'm experiencing with KDE/kdm: I'm able to login from a client (martin) and everything is fine. The problem is when I logout from KDE, after that the client's display starts reseting, until I restart X with <Ctrl-Alt-Del>. I get a series of the following messeges in the syslog: "Nov 22 12:08:35 Trapito-Testing kdm: martin:0[13982]: IO Error in XOpenDisplay" "Nov 22 12:08:35 Trapito-Testing kdm[12
10:13
<sbalneav>
martinfernandez: Sounds like some kind of network problem.
10:13
Either that, or the number of concurrent XDMCP sessions configured in KDM is too low.
10:14
<martinfernandez>
sbalneav: I will look for that in the kdmrc.
10:16
<psycodad>
is there a way to set the mouse speed and/or acceleration for a rdesktop screen ?
10:17
or for other sessions too, in KDE i managed to decrease it to be usable by xset m 1/3

10:47
<sbalneav>
what kind of machine is it? What kind of network card does it have? Processor? Amount of memory? Video card? We need some more information.

<ccesario>
sbalneav, 2 pentium III 500Mhz, only init 3, and rtl-8139
10:52
the machines are equals
10:53
<sbalneav>
ccesario: Well, if they're equals, then you've probably got a hardware problem with one of them, or you've got a bad port on your network. What kind of switch do you have? Is it a smart switch? We've had people with cisco switches that blocked tftp traffic.
10:56
<ccesario>
sbalneav, no, the machines is ok!, I tested with boot recovery floppy and is working
10:57
<sbalneav>
Then it's your network.
10:57
Check your switch.
10:59
<ccesario>
Is OK... :/
11:01
<sbalneav>
What kind of switch is it?
11:03
<coldfire>
swap the ports that the clients are plugged into to see if the problem persists

<bintut>
using the dhcpd.conf in http://wiki.ltsp.org/twiki/bin/view/Ltsp/DHCP what will happen with the pxelinux.0 or the ltsp kernel if the standalone workstations automatically acquires ip addresses from the dhcpd server but boots from its own operating system and not from ltsp?
11:27
i mean, the dhcpd.conf at http://wiki.ltsp.org/twiki/bin/view/Ltsp/DhcpExample
11:29
<sbalneav>
It will just get ignored.
11:29
The dhcp server simply passes along the information. It's up to the client to make use of it.
11:31
A PXE boot client asks for the information, then uses the tftp server to download the boot file.
11:31
If the kernel's already there, the kernel's going through it's own boot process.
11:33
<bintut>
sbalneav: thanks a lot.. :)
11:39
sbalneav: do you think my /etc/dhcp3/dhcpd.conf at http://paste.debian.net/17096 is good enough? my dhcpd server is a separate box.. the only dhcpd server for my ltsp servers and standalone workstations (windows/linux)
11:40
<sbalneav>
I can't really say. Best way to find out is to try it. :)
11:41
<bintut>
i'm still in my house.. i'm preparing for it here.. i'll be in the office tomorrow.. it's actually very late at night here.. :)
11:42
sbalneav: i'll try my config tomorrow when i report to the office..
11:57
i have to go.. later..
