 |

Voila le mail que j'ai envoyé a la mailingg list de pxelinux
j'ai la fleme de traduire, je pense que vous comprendrez 
donc vala, si jamais vous avez deja eu le problème ou une idée...
| Code: | Hello !
I'm french, my english is bad :-(
I want to boot a computer by network which have a 3Com network card. So I use isc-DHCP, TFTP-hpa and PXELinux.
The computer start, make a dhcp request, receive the configuration.
The next step is to contact the tftp server to get pxelinux.0 and the configuration.
Stop me if I made an error ;)
So, in the network I want to use it, there is a dhcp server, which cannot do tftp server (his name is packa). And I have another computer which have a tftp server and that's all on it (his name is srvbck). And there is a last one which is the client and have the name vmware (not because of the software)
At the boot, dialogs are like that (first are up, last are down):
SRVBCK PACKA VMWARE
DHCP REQ
DHCP ACK
TFTP REQ
pxelinux.0
TFTP SEND
pxelinux.0
TFTP REQ
pxelinux config files
TFTP SEND
pxelinux config files
And go on....
You can see here that the dhcp dialog is good
but the tftp one is not :
the request for the file pxelinux.0 is to packa and not to srvbck (the problem is here)
and the config files are ask to srvbck (and that's good)
Here is the /etc/dhcp3/dhcpd.conf important lines :
ddns-update-style none;
option domain-name "isaac.ftrd";
log-facility local7;
subnet 193.252.239.16 netmask 255.255.255.240 {
option broadcast-address 193.252.239.31;
option routers 193.252.239.26; -----> IP Adress of srvbck
option subnet-mask 255.255.255.240;
option domain-name-servers 193.252.239.27; -----> IP Adress of packa
allow bootp;
allow booting;
default-lease-time 600;
max-lease-time 7200;
option tftp-server-name "193.252.239.26";
next-server 193.252.239.26;
filename "/pxelinux.0";
option ntp-servers 193.252.239.27;
option vendor-class-identifier "PXEClient";
option vendor-encapsulated-options 09:0f:80:00:0c:4e:65:74:77:6f:72:6b:20:62:6f:6f:74:0a:07:00:50:72:6f:6d:70:74:06:01:02:08:03:80:00:00:47:04:80:00:00:00:ff;
host vmware {
hardware ethernet 00:04:75:7D:8D:80;
fixed-address 193.252.239.28; -----> IP Adress of vmware
option host-name "vmware";
}
}
You can see that the option next-server is place in the goal that vmware contact srvbck for the tftp transfert, but srvbck is contact on the second transfert (after pxelinux.0)
Is it a bug ? Is it a 3Com pxe client bug ?
How can I resolv the problem ?
I really cannot put a tftpserver on the same computer which serv the dhcpd.
Thanks
