I don=B9t think that there is a current port for this but this program http://dhcp-agent.sourceforge.net/ but dhcp-agent alleges to have a sniffer option. http://dhcp-agent.sourceforge.net/man/dhcp-sniff.1.html I haven=B9t used it but I recall stumbling upon this a while back when I was looking for the same. If you try it out, let me know if it works. -J On 5/12/08 9:34 AM, "Wojciech Puchar" wrote: > is there an option in dhclient (or other program) to try getting IP > address but - don't set anything in system. >=20 > i mean something to just check for dhcp servers. >=20 > or maybe something that just detects what DHCP servers are available. >=20 >=20 >=20 > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.o= rg" >=20 --=20 Johan Dowdy - CISSP Senior Systems Administrator nCircle Network Security =20 415.318.2880 "Any sufficiently advanced technology is indistinguishable from magic." -- Arthur C.
