wireshark packet capture filter on string

In the example below, the secs value 0x0e00 (3584, or nearly an hour) was sent by a Windows XP client, even though the client hadn't been retrying that long. Wireshark will attempt to detect this and display the message 'little endian bug?' in the packet detail. Most versions of Microsoft Windows improperly encode the secs field on the wire as little-endian. BOOTP: DHCP uses BOOTP as its transport protocol.RFC3396 'Encoding Long Options in the Dynamic Host Configuration Protocol (DHCPv4)' November 2002 RFC2131 'Dynamic Host Configuration Protocol' March 1997, updated by RFC3396 RFC1541 'Dynamic Host Configuration Protocol' October 1993, obsoleted by RFC2131 RFC1531 'Dynamic Host Configuration Protocol' October 1993, obsoleted by RFC1541 Some operating systems (including Windows 98 and later and Mac OS 8.5 and later) use APIPA to locally assign an IP-address if no DHCP server is available. Dynamic Host Configuration Protocol (DHCP)ĭHCP is a client/server protocol used to dynamically assign IP-address parameters (and other things) to a DHCP client.
