m300107Thanks I've got an etherboot cdrom but it doesnt seem to pick up my NIC. I'm trying to boot with helix to see the lspci card output for the NIC, but since I've got a small hard drive it might be simpler and quicker to boot up on that01:36
cliebow m300107:can you boot to ubuntu live cd/install cd and get a pci id?01:37
cliebowor knoppix or mandrake move?01:39
m300107<cliebow>:I'm trying to boot with my Helix CD right now, but am having problems with the boot parms because it's got almost NO memory01:39
cliebowcan you see the chip:get any info from it?01:43
cliebowyou/ll need prob 128 for ubuntu..i get by with 32 in ltsp-4.201:44
cliebowas far as a thin client is concerned01:44
m300107I'm still trying to read the lspci output for the card by boot the machine up. But this is proving a big headache with 32M. Can you get this info straight off the card?01:50
cliebowprob not..unless it is obvious..like rtl8139 or 3com01:52
m300107Er netgear, not much information from their website either01:58
=== stgraber [n=stgraber@client80-83-51-125.abo.net2000.ch] has joined #edubuntu
m300107ahh at last, lspci output. The ethernet controller for the netgear card:02:17
cliebowthat is tough without the pci id..since some are via-rhine and some are other02:17
m3001070000:00:08.0 Ethernet controller: Realtek Semiconductor Co.,Ltd RTL-8139/8139C/8139C+ (rev 10)02:18
m300107So I guess that's the code I need for the rom-o-matic thing02:19
cliebowok that is the slot02:19
cliebownow lspci -n for the id02:19
cliebowin thaT SLOT02:19
cliebowprob ends with 813902:20
cliebow10ec:8139?02:21
m300107Ah, OK, looks like 10ec:813902:21
m300107good guess!02:21
cliebowi use a lot of them..they tend to be very easy02:22
cliebowyou cana use whatever version you like but 5.0.11 has been rock solid for years02:22
cliebowin etherboot02:22
m300107Now off to Rom-o-matic again for the etherboot cd, because this disk is just too slow. my fingers were itching for a tuxracer thing for ages02:22
cliebowheh..id be surprised if the cd doesnt have it..can you just boot from floppy?02:23
cliebowfor starters?02:23
m300107none of my other machines have floppy, so it'd be a bit hard to transfer the image. this machine is wonderfullly built inside but just too old02:24
cliebowive neverused the cd...not a prom slot anywhere?02:25
cliebowthey do have a floppy controller ?02:25

m300107Hi got it to boot. Problem now is that my DHCP server is a OpenWRT Linksys with no space on it. The TS will have to be my Ubuntu 6.10 file server on 192.168.1.2. So I guess I'll have to tweak the rom-o-matic setting "DEFAULT_BOOTFILE" to point to 192.168.1.2. Where are the boot files kept? Which ports do I have to open in the firewall?02:37
m300107I've installed the edubuntu-server package02:42
m300107... but I can't find any files under /opt/ - anyone know how to install them under Ubuntu 6.1002:59

cliebow m300107:you'd be better off to shut off dhcp in the router and run dhcp on the ts03:25
cliebowm300107:apt-get install ltsp-server-standalone03:25
cliebowthat Will turn on dhcp in your ts.03:26
cliebowbest to hard code an address for your server nic03:26
m300107[headache factor increasing by 10]  but the router is the only thing here that stays on all the time, and it gives DHCP address to other clients too.03:30
m300107I guess I could use the TS to give out a different range within the same subnet mask. The router would still let them in, wouldn't it?03:31
m300107hard-coding the server nic: those are the static_server_ip options in the ROM-O-Matic options, I guess.03:33
cliebowyou will not get a root-path from your router on second dhcp if you dont do something] ..i habvnt messed with those options..best not ot03:37
cliebowyou could put a second nic in..one for your clients on a seperate switch..one for your reg network03:38
cliebowandf hard code the "internal" nic03:39
m300107I've got the schooltool listening on 7080 on my TS03:39
m300107second nic might be the thing, though03:39
cliebowOR..[headache factor increasing]  you could use alternate port for your dhcp03:40
m300107this is only  a home network, i can use a a range within the dhcp addresses from my router for the 1 or 2 thin clients.03:41
=== cbx33 [n=pete@ubuntu/member/cbx33] has joined #edubuntu
m300107then the rom-o-matic settings include a STATIC_BOOTFILE setting which I could perhaps set to the TS. [hoping not to have to reset my dhcp / router settings] 03:42
cbx33hey all03:43
cliebowm300107:dang your nick is long.you cant use that dhcp to provide filename or root-path can you?03:44
cliebowcbx33:howdy03:45
cbx33hi cliebow03:45
m300107cliebow you been whois me? this is my laptop. not the old piece of junk i want to give to my daughter on mon03:46

cliebowno i havnt but m3 etc etc is a little vgerbose 8~)03:47

=== matsavhalev_ [n=matsavha@CBL217-132-146-112.bb.netvision.net.il] has joined #edubuntu
m300107OK, I'm going to give up on my router settings and setup DHCP on the TS as you suggest03:53
cliebowthe big thing is what you are going to boot with...a floppy is easy..never tried alternate dhcp from a cd..03:55
cbx33hmmm03:55
cliebowm300107:ive always d/l ed etherboot source and changed dhcp call myself..never used the port 1067 provided by etherboot03:57
m300107<cliebow>: which extra ports should I open on my server for the dhcp and terminal server?03:59
cliebowyou'll need 67/8 for dhcp 69 for tftp 2049 for nfs 6000 for x ssh on 22 if using edubuntu-ltsp04:03
m300107cliebow: how do you change the dhcp call? I guess it is easier to alter a floppy, but which settings04:03
m300107thx04:04
cliebowltsp-server-standalone does most for you...to change dhcp listening port in /etc/init.d/dhcp3-server add -p 1067 to the startup call..looki nwiki./.ltsp.org for dhcp alternate port04:04
cliebowil be back in a bit04:05

cbx33oooh mumma, phimage is looking nice now ;)05:43

m300108I've got DHCP up and the client is looking for /ltsp/i386/nbi.img (am still booting from cdrom). the client-build prog installed a whole distro under /opt/ltsp/i386/06:24
m300108 but no image file. I've got no floppy drive outside this ancient box w/ exception an old sun box here. How do I get the boot image?06:24
m300108The /etc/ltsp/dhcp.conf points to an image file:06:25
m300108 if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {06:25

m300108  option root-path "/opt/ltsp/i386";06:25
m300108}06:25
m300108AH, the files seem to be in /var/lib/tftpboot/ltsp/i386/ - let's see if I can link them in..06:28
m300108Right, I never thought I'd get excited about seeing dots march across the screen, but this ancient box looks like it might be booting. It is _very_ slow though. Shouldn't it be fast on a server?06:33
m300108the thing it is running on is amd6406:33
cliebowtakes my dots about 3/4 of a second06:33
m300108hmm, may be a firewall issue then.06:34
cliebowno your etherboot is still looking at port 67? and trying to get a filename from your router..06:35
cliebowleem get the pice for you that gives the initramfs correct port to do second dhcp06:35
m300108didn't alter the etherboot settings on either client or server06:36
m300108my router doesn't have much space on it for image files.06:36
cliebowit is not smart enough to give the filename statement anyway06:37
cliebowoption option-128 e4:45:74:68:00:00;06:37
cliebowoption option-129 "DPORT=1001";06:37
cliebowthat tells the initramfs that at second dhcp..looking for option root-path..to use port 100106:38
m300108are those lines in /etc/ltsp/dhcp.conf?06:38
cliebowyes06:39
m300108option option-128 e4:45:74:68:00:00; -is that MAC-address-specific?06:39
cliebowNo No06:42
cliebowNOT a Mac address06:42
m300108I put those lines in but a restart of /etc/init.d/dhcp3-server restart caused errors: dhcpd self-test failed. Please fix the config file.06:43
cliebowit looks like only later versions than 5.0.11 will let yo change alternate dhcp port (from the website).it can be done manually using source code06:44
cliebowprob left out a semicolon06:44
cliebowthose lines taken from a working server...06:47
