Re: DHCP reply with opt82
Thanks Alan, but git pull said that local sources are up to date.

Re: DHCP reply with opt82
Sources, server version and dictionary was ok.
The problem was in using old attributes:
DHCP-Agent-Circuit-Id := %{request:DHCP-Agent-Circuit-Id}
DHCP-Agent-Remote-Id := %{request:DHCP-Agent-Remote-Id}
Changed them to:
DHCP-Relay-Circuit-Id := %{request:DHCP-Relay-Circuit-Id}
DHCP-Relay-Remote-Id := %{request:DHCP-Relay-Remote-Id}
and now it works without any problem.
Debug still shows old attibute DHCP-Agent-Circuit-Id and doesn't show remote
id at all:
Received DHCP-Discover of id 4a76b25e from 1.1.1.1:67 to 0.0.0.0:67

Yes, that should be it.
dictionary.dhcp is from 2.1.10
Are you *sure*? The version in the source is from 2.1.10. What about
the installed version? (/usr/local/share/freeradius/...) Go *check*.
but result is the same (tcpdump):
Agent-Information Option 82, length 6:
Unknown SubOption 0, length 4:
0x: 01e3 0420
Agent-Information Option 82, length 8:
Unknown SubOption 0, length 6:
0x: 001f cab0 ef00
What am I doing wrong?
Probably not using the right dictionary, or the right version of the
server.
When I perform the test that's in the git commit message, I get the
correct sub-option format. Please try that. If you don't get the
correct suboptions, then you need to use the right dictionary and/or the
right source code.

Uh... no. The dictionary.dhcp that is included with 2.1.10 has the
*same* definition for those attributes.
ATTRIBUTE DHCP-Agent-Circuit-Id 1 octets
ATTRIBUTE DHCP-Agent-Remote-Id2 octets
ATTRIBUTE DHCP-Relay-Circuit-Id 1 octets
ATTRIBUTE DHCP-Relay-Remote-Id2 octets
They are in the DHCP-Relay-Agent-Information TLV.
If you have ANYTHING ELSE for these attributes, then you are not using
the correct dictionary.
Changed them to:
DHCP-Relay-Circuit-Id := %{request:DHCP-Relay-Circuit-Id}
DHCP-Relay-Remote-Id := %{request:DHCP-Relay-Remote-Id}
and now it works without any problem.
Which indicates that you're not using the correct dictionary.dhcp file.
Debug still shows old attibute DHCP-Agent-Circuit-Id and doesn't show
remote id at all:
If the debug log shows DHCP-Agent-Circuit-Id, it's because you are
using the OLD dictionary.dhcp file. Go fix that.
The OLD file had DHCP-Agent-* listed LAST, which over-rode any
previous definitions.
The only issue left in the version you have is that it looks like the
*first* attribute inside of option 82 is printed in debug mode, and the
others aren't printed. But a tcpdump shows that all of them are in
the packet.
I'll put a fix for the debug output for 2.1.10.
