krb5_get_all_client_addrs, krb5_get_all_server_addrs – return local addresses

LIBRARY SYNOPSIS DESCRIPTION SEE ALSO

Kerberos 5 Library (libkrb5, -lkrb5)

#include <krb5.h>

krb5_error_code
krb5_get_all_client_addrs(krb5_context context, krb5_addresses *addrs);

krb5_error_code
krb5_get_all_server_addrs(krb5_context context, krb5_addresses *addrs);

These functions return in 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.

The returned addresses should be freed by calling krb5_free_addresses().
