If the -d option has parameters, they tell which source +code files have debugging activated. One can use wild cards in file names. +Example: + -d Activate all normal debug prints + -d src/service.c This prints debugging info from src/service.c + file only + -d src/network.c:src/ipconfig.c + This activates debug prints in src/network.c + and src/ipconfig.c files. + -d 'src/n*.c' This would activate debug print from all the C source + files starting with letter 'n' in src directory. + Note the quotation marks around option, that is to + prevent shell expansion. + -d '*/n*.c:*/i*.c' Activate debug prints for all C source files starting + with letters 'n' or 'i' in any sub-directory. + +Some components of ConnMan have environment variable activated debug prints. +If the environment variable is set, then corresponding component will print +some extra debugging information. +Following environment variables can be used: + CONNMAN_DHCP_DEBUG DHCPv4 related debug information + CONNMAN_DHCPV6_DEBUG DHCPv6 related debug information + CONNMAN_IPTABLES_DEBUG Extra information when iptables is used + CONNMAN_RESOLV_DEBUG Name resolver debug prints. These debug prints + are used when ConnMan resolves host names for + its own use. + Note that the DNS proxy debug prints do not + use this environment variable. For that, one + can use "-d src/dnsproxy.c" command line option. + CONNMAN_SUPPLICANT_DEBUG Debugging prints for communication between + connmand and wpa_supplicant processes. + CONNMAN_WEB_DEBUG Debug information when ConnMan does Internet + connectivity check in Wispr and 6to4 components. + +Example: + CONNMAN_WEB_DEBUG=1 src/connmand -n + + Kernel configuration ==================== |
