X-Comment: Discussion of DHCP for IPv4
Hi everybody,
I want to run a DHCP-Server on IBM AIX 4.2 and a lot of Win95 DHCP clients and I
got problems:
The very first time when a Win95 client gets his configuration from the AIX
everything is ok. Now I make some changes to my server's config-file, especially that the
client (defined by his MAC-Address) has to get another IP address, another hostname,
and another value for the DNS-Server. And this doesn't work !
The W95 client insists on his formerly achieved address.
Examing the packets shows following handshake:
Win95 Client AIX Server
DHCPDISCOVER ------------------------------>
ClientID=MAC-addr
Requested IP-Addr=old one
Hostname Option=old one
<----------------------------- DHCPOFFER
Renewal time ...
Rebinding time ...
Server ID ...
Hostname option = NEW NAME
Netmask ...
Router Option ...
DNS server = NEW SERVER NAME
Broadcast address ...
IP address lease time ...
DHCPREQUEST ----------------------------------->
ClientID=MAC-addr
Requested IP-Addr=OLD ONE
Server ID ...
Hostname Option=OLD ONE
Parameter Request List ...
Vendor specific information ...
<--------------------------------- DHCPACK
Renewal time ...
Rebinding time ...
Server ID ...
Hostname option = NEW NAME
Netmask ...
Router Option ...
DNS server = NEW SERVER NAME
Broadcast address ...
IP address lease time ...
Looks fine, but the Win95 obviously doesn't care about the OFFER and ACK and
changes nothing.
Has anybody any idea ?
Is anybody running this configuration (AIX-Server / Win95 Client) ?
Does anybody know something about these Vendor specific information used
by the Win95 clients ?
Any help welcome, thanks in advance
