Default AW: ltsp-update-image -> 2nd dhcp

Hi Steve,


¬*


thanks for the info, but
I have no idea what you are talking about J


¬*


I don’t think that
Gutsy has anything complicated like this included. Everything else got easier.
So I think there must be another solution.


¬*


But waiting for 2 Month
for a solution is quite frustrating…

I might be completely
wrong, but it seems to me that the second DHCP call will take place
automatically as ifup is called as a result of the udev rules in
/opt/ltsp/i386/etc/udev/rules.d/85-ifupdown.rules. You may be able to modify
the rule concerned to call a script that does the same job as ifup, by manually
calling ifconfig and the dhclient with the port number set. This is pure
speculation on my part, I haven't tried this!

I checked that. 2.6.22-14 is in tftp and is created.

vmlinuz is this version but the date is from October.

initrd.img is todays date

You are absolutely right with the 2nd dhcp - thats where i am stuck for

month!!

Where can I change the dhclient behaviour?

Under Feisty it was the -p 1068 Option in the nfs-script. Then I had to

run mkelf-linux and created

nbi.img-2.6.22-14-386, vmlinuz-2.6.22-14-386 and

initrd.img-2.6.22-14-386 ( with Feisty kernel numbers)



Now it seems only initrd.img-2.6.22-14-386 is changed:



root@edubuntu:/var/lib/tftpboot/ltsp/i386# ls -l

-rw-r--r-- 1 root root¬*¬* 75391 2007-10-15 03:35 config-2.6.22-14-386

lrwxrwxrwx 1 root root¬*¬*¬*¬*¬*¬*24 2008-01-30 16:06
initrd.img ->

lrwxrwxrwx 1 root root¬*¬*¬*¬*¬*¬*21 2008-01-30 16:06
vmlinuz ->

vmlinuz-2.6.22-14-386

-rw-r--r-- 1 root root 1696312 2007-10-15 03:35 vmlinuz-2.6.22-14-386



Booting up to the second dhcp-request works fine.



How does the client get a ip at the 2nd step????????



thanks toni



ps



a part of the dhcp.conf. - maybe this gives any clou:



option option-128 code 128 = string;

option option-129 code 129 = text;



subnet 192.168.2.0 netmask 255.255.255.0 {

¬*¬*range 192.168.2.80 192.168.2.99;

¬*¬*option domain-name "kaser.local";

¬*¬*option domain-name-servers 192.168.2.1;

¬*¬*option broadcast-address 192.168.2.255;

¬*¬*option routers 192.168.2.10;

¬*¬*option subnet-mask 255.255.255.0;

¬*¬*option option-128 e4:45:74:68:00:00;

¬*¬*option option-129 "DPORT=1067";

¬*¬*next-server 192.168.2.10;



¬*¬*if substring( option vendor-class-identifier, 0, 9 ) =
"PXEClient" {

¬*¬*¬*¬*filename "/ltsp/i386/pxelinux.0";

¬*¬*}

¬*¬*else{

¬*¬*¬*¬*filename "/ltsp/i386/nbi.img";

¬*¬*}

¬*¬*option root-path "192.168.2.10:/opt/ltsp/i386";
