Hi, I'm using dnsmasq as supplied with OpenWrt WhiteRussian RC6:
root@OpenWrt:~# dnsmasq -v Dnsmasq version 2.33 Copyright (C) 2000-2006 Simon Kelley Compile time options IPv6 GNU-getopt ISC-leasefile no-DBus no-I18N I'm trying to get it to generate an RFC 3361 "SIP server" option, code 120, but I can't make it work. A tcpdump -X on the client shows that this option isn't being included. I've added the following to the end of /etc/dnsmasq.conf : # SIP server (RFC 3361) dhcp-option=120,1,192.168.1.1 and I don't get the option. But strangely, changing this to dhcp-option=42,192.168.1.1 *does* add an NTP server option into the response. I also tried adding -O 120,1,192.168.1.1 to the command line, to no effect. The test client is a Linux laptop running dhclient from CentOS 4.4. Any suggestions as to what I'm doing wrong? Thanks, Brian Candler.
