Dhclient not send option 77

fredlubrano

Hi,

Excuse me to open this subject here, but this concerns the beta 2.4
The subject has already been discussed in "pfSense English Support -> DHCP and DNS" dhclient does not support option 77 "

I confirm that "option-77" or user-class is not sent by dhclient on pfsense 2.4.
View my result dhcpdump :

I have taken the mods that were carried out on the 2.3 dhclient and applied them to the freebsd 11 client. If you wish you can try the file attached.

One of my testers also needs this for his French abode ( Orange ).

It's not tested and is hot off the compiler.

Thanks Fred, that's good news, I'll try and get it PR'd into the main FreeBSD11 code.

Fred, you say the client was working in 2.3, yet the developers are saying there have been no changes made to dhclient. Please can you post on the link below on GitHub and give any useful information.
