LIBRARYKerberos 5 Library (libkrb5, -lkrb5)
SYNOPSISIn krb5.h Ft krb5_error_code Fn krb5_get_all_client_addrs krb5_context context krb5_addresses *addrs Ft krb5_error_code Fn krb5_get_all_server_addrs krb5_context context krb5_addresses *addrs
DESCRIPTIONThese functions return in Fa addrs a list of addresses associated with the local host.
The server variant returns all configured interface addresses (if possible), including loop-back addresses. This is useful if you want to create sockets to listen to.
The client version will also scan local interfaces (can be turned off by setting libdefaults/scan_interfaces to false in krb5.conf ) but will not include loop-back addresses, unless there are no other addresses found. It will remove all addresses included in libdefaults/ignore_addresses but will unconditionally include addresses in libdefaults/extra_addresses
