Hi all,
this [1] wiki article mentions a option called "local-proxy-config". However,
this option is neither documented in the manpage nor in the documentation. I
even cannot use it in Ubuntu 16.04 (isc-dhcp-server version is 4.3.3). Is it
something gentoo-specific?
However, how can I provide a proxy configuration file via isc-dhcpd?
Thanks in advance!

"local-proxy-config" is a user defined label for the dhcp option number
252. This number is in the user defined range, but Microsoft chose to use
it for this function in Internet Explorer, other browsers followed this.
There are two parts to that setting and they are given in the article. The
first one defines the option and says that dhcp option number 252 is to be
encoded as a text string:
option local-proxy-config code 252 = text;
and the second one where a value is assigned:
option local-proxy-config "http://www.example.org/proxy.pac";;
For this to work you need to select the "automatically detect the proxy"
setting in your browser. The exact name varies with the different
browsers.

Not all browsers use prox auto detection via dhcp.
In example, Mozilla Firefox uses only DNS to detect proxy settings.

Hi there,
currently I want to get a DHCPv6 prefix delegation with a fixed assignment
working with a mobile operator.
The CISCO P-GW is sending me the 3GPP-IMSI as a USER-CLASS:
DHCPv6
Message type: Relay-forw (12)
Hopcount: 0
Link address: 2a01:81c::4:2
Peer address: 2a01:81c::4:1
Relay Message
Option: Relay Message (9)
Length: 88
Value: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
DHCPv6
Message type: Solicit (1)
Transaction ID: 0x09c1b4
Elapsed time
Option: Elapsed time (8)
Length: 2
Value: 0000
Elapsed time: 0 ms
Client Identifier
Option: Client Identifier (1)
Length: 15
Value: xxxxxxxxxxxxxxxxxxxxxxxxxxxx
DUID: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
DUID Type: link-layer address plus time (1)
Hardware type: Ethernet (1)
DUID Time: Sep 7, 2046 01:32:22.000000000 Mitteleurop?ische
Sommerzeit
Link-layer address: xxxxxxxxxxxxxxxxxxxxxxxxxx
--------
User Class
Option: User Class (15)
Length: 10
Value: 00010203040506070809
------
Identity Association for Prefix Delegation
Option: Identity Association for Prefix Delegation (25)
Length: 41
Value: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
IAID: 00000000
T1: 82800
T2: 82800
IA Prefix
Option: IA Prefix (26)
Length: 25
Value: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Preferred lifetime: 165600
Valid lifetime: 165600
Prefix length: 56
Prefix address: 2001:2001:20:200::
Interface-Id
Option: Interface-Id (18)
Length: 4
Value: 00000068
Interface-ID: 00000068
Consequently I was configuring the DHCP - Server as follows:
....
host myrouter {
host-identifier option user-class "00:01:02:03:04:05:06:07:08:09";
fixed-prefix6 2001:2001:20:200::/56;
}
...
Unfortunately I got stuck :(!
Could anyone give me an advice?
Thank you in advance
Wolfgang
