Hi,

I'm testing dhcpd sync features and I'm getting errors due to wrong HMAC calculation.
(not getting back note("DHCP_SYNC_LEASE from....).

sync_recv() is exiting in HMAC calculation in /* Compute and validate HMAC */ (line 283)

After applying the diff bellow problem seems to be solved. Could someone have a look?

regards,

Giannis
