# [NAME](#NAME)

`krb5_get_all_client_addrs`, `krb5_get_all_server_addrs` — return local addresses

# [LIBRARY](#LIBRARY)

Kerberos 5 Library (libkrb5, -lkrb5)

# [SYNOPSIS](#SYNOPSIS)

`#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`);

# [DESCRIPTION](#DESCRIPTION)

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`](#krb5_free_addresses)().
