menuconfig TCPDUMP bool prompt "tcpdump " select LIBPCAP select OPENSSL if TCPDUMP_DISABLE_CRYPTO help Tcpdump prints out the headers of packets on a network interface that match the boolean expression. It can also be run with the -w flag, which causes it to save the packet data to a file for later analysis, and/or with the -r flag, which causes it to read from a saved packet file rather than to read packets from a network interface. In all cases, only packets that match expression will be processed by tcpdump. config TCPDUMP_ENABLE_CRYPTO bool prompt "enable crypto support" depends on TCPDUMP depends on BROKEN help Select this, if you don't need support for encryption (e.g. IPsec ESP packets) config TCPDUMP_SMB bool prompt "enable possibly-buggy SMB printer" default y depends on TCPDUMP help Notes from configure, when this entry is checked: The SMB printer may have exploitable buffer overflows!!! config TCPDUMP_IPV6 bool depends on TCPDUMP select LIBPCAP_IPV6 default no prompt "enable ipv6 (with ipv4) support" help Enable this if you require ipv6 support. This also requires ipv6 support in libpcap (already done if you check this entry)
