DESCRIPTION
\nThis command allows the system administrator to check if a remote DHCP server is still functioning.<\/p>\n

Options are:<\/p>\n

-v\u00a0\u00a0 Verbose, print some information.<\/p>\n

-i\u00a0\u00a0 Use DHCPINFORM packets.<\/p>\n

-r\u00a0\u00a0 Use DHCPREQUEST packets (default behaviour).<\/p>\n

-q\u00a0\u00a0 Quiet, print nothing on the screen.<\/p>\n

-t maxwait
\nMaximum time to wait for an answer from the server in seconds.\u00a0 Default is 3 seconds.<\/p>\n

-c client-IP-address
\nRequest this IP address. Note that this is also the IP address the answer will be sent to.<\/p>\n

-s server-IP-address
\nSend the DHCP packet to this IP address.<\/p>\n

-h client-hardware-address
\nUse this hardware-address in the DHCP request. It can be up to sixteen octets seperated by colons (i.e.
\n01:02:03:04)<\/p>\n

-g gateway-IP-address
\nUse this IP address for the gateway IP address in the DHCP packet.\u00a0 This option is currently broken.<\/p><\/div>\n
