| 03:28 | <knipwim> is this the correct format for /etc/ltsp/ltsp-build-client.conf?
| |

| |
| 03:30 | and why is it not included in all distributions by default?

| 03:52 | <schregge> hi
| |
| 03:52 | how can i pass kenel parameters to a specific thinclient?
| |
| 03:53 | (apic/noapic)
| |
| 03:53 | <alkisg> schregge: etherboot or pxe?
| |
| 03:54 | <klausade> schregge: i would use pxelinux.cfg/default
| |
| 03:54 | <alkisg> pxelinux.cfg/01-<mac-address> for a specific client, but that's ONLY for pxe clients
| |
| 03:55 | <schregge> pxe
| |
| 03:55 | ok thanks

| 06:45 | <cyberorg> alkisg, hi, changed defaults for live DVD, it should now work with existing dhcp server, IP address of the dvd would have to manually changed according to existing setup

| 06:53 | <alkisg> Hey cyberorg! Did you use dnsmasq for this?
| |
| 06:55 | <cyberorg> alkisg, nopes, kiwi already had that feature :)
| |
| 06:55 | http://en.opensuse.org/LTSP/Tips_and_Tricks#Using_another_DHCP_server.2C_not_on_LTSP_server
| |
| 06:55 | <alkisg> But if the existing dhcp server doesn't give a filename, how are the clients going to boot?
| |
| 06:55 | <cyberorg> we made that default now
| |
| 06:56 | alkisg, we have dhcpd running on ltsp server
| |
| 06:56 | <alkisg> cyberorg: it says this: "You need to configure your original DHCP server (not the ltsp) , by editing it's dhcpd.conf: "
| |
| 06:56 | <cyberorg> alkisg, that is if we dont want second dhcpd at all
| |
| 06:56 | <alkisg> I'm saying that in the case where I *can't* reconfigure my original dhcp server, then I can't boot...
| |
| 06:56 | <cyberorg> in that case appending kiwiserver=192.168.1.231 kiwiservertype=tftp is enough
| |
| 06:57 | we now append that by default
| |
| 06:57 | <alkisg> cyberorg: Let me get this from the beginning. I have a router which acts as a dhcp server. It cannot be programmed to give a filename.
| |
| 06:57 | How can I boot ltsp in the same switch?
| |
| 06:58 | Answer: (1) make the ltsp server a proxydhcp, or (2) have multiple dhcp servers in the same switch. The first one is a "correct" way to do it, the second one is a little tricky.
| |
| 06:59 | <cyberorg> alkisg, simply configure IP statically, name server and gateway of ltsp server, run easy-ltsp > prebuilt image
| |
| 06:59 | <alkisg> cyberorg: statically where, in the pxe clients?
| |
| 06:59 | <cyberorg> we would have two dhcp servers in same network
| |
| 06:59 | on the server
| |
| 06:59 | <alkisg> How are the clients going to get an ip?
| |
| 06:59 | <cyberorg> alkisg, ltsp server will give them
| |
| 07:00 | router will not answer PXE requests
| |
| 07:01 | <alkisg> Most cheap router/modems do have an embedded dhcp server
| |
| 07:01 | Most greek schools use such a server to hand out dhcp leases
| |
| 07:01 | <cyberorg> alkisg, yes, but they dont answer pxe requests
| |
| 07:01 | try it, it works :)
| |
| 07:02 | some people have it in production already
| |
| 07:03 | <alkisg> cyberorg: I know it *can* work, I've tried all possible dhcp combinations :P But you have to rewrite dhcpd.conf if you only have 1 nic.
| |
| 07:03 | <cyberorg> alkisg, trust me, in kiwi-ltsp setup you will not have to change anything on other dhcp server
| |
| 07:04 | <alkisg> No, not in the other dhcp server, in the ltsp server you have to change dhcpd.conf.
| |
| 07:04 | I know you have a script to do that (easy-ltsp what was its name)
| |
| 07:04 | But it won't cooperate with the existing dhcp server
| |
| 07:04 | It'll use the same range...
| |
| 07:04 | <cyberorg> alkisg, you can specify range you want
| |
| 07:05 | <alkisg> Yes, so you need to do it manually.
| |
| 07:05 | A proxydhcp is the correct way to do that, that's why I'm waiting for the next dnsmasq version. Everything would be done automatically.
| |
| 07:05 | ...because the ltsp-server will have nothing to do with ip leases, it'll just provide the filename and other boot info.
| |
| 07:05 | <cyberorg> alkisg, either do it manually or from easy-ltsp, dhcpd.conf is auto generated
| |
| 07:06 | <alkisg> cyberorg: if I have a network of 10.10.10.x, and my router/dhcp server hands out addresses in the range 10.10.10.2 to 10.10.10.254, then there's no way to make it work correctly.
| |
| 07:06 | (with 1 nic)
| |
| 07:06 | <cyberorg> this setup will work either you have existing dhcp server or not
| |
| 07:07 | <alkisg> You'll have to modify the existing dhcp server, *or* use multiple IPs in the ltsp server nic
| |
| 07:07 | There's no way to cover all the possible cases/problems with normal dhcp3-server. proxydhcp is the way to go...
| |
| 07:08 | <cyberorg> alkisg, well we can get it working 90% of the time it is ok :)
| |
| 07:09 | <alkisg> cyberorg: wait for the next dnsmasq version, I'll make a script for an ltsp-server to automatically initialize itself in any network. If you like it, you may use it then...
| |
| 07:09 | <cyberorg> alkisg, ok, till then you can use this solution :)
| |
| 07:10 | <alkisg> (really simple, 1) get an ip with dhclient, 2) run dnsmasq as a proxydhcp)
| |
| 07:10 | cyberorg: you're doing a fine job, thanks for that.
| |
| 07:11 | <cyberorg> i think i've also added dhsmasq app on the DVD, so as soon as new version is out it will be there
| |
| 07:13 | yup it's there

| 08:55 | <knipwim> the ltsp-build-client.conf file is not a feature for all distributions right?
| |
