libnuclient(3) NUFW client authentication library


#include <nuclient.h>

NuAuth * nu_client_init (const char *nptr, char *username, unsigned long userid, char * password, char * hostname, unsigned int port, char protocol, char ssl_on);

int nu_client_check (NuAuth * session);

void nu_client_free (NuAuth *session);


This manual page documents the libnuclient library.

Use nu_client_init to initialize a authentication session. Then call nu_client_check at regular interval to send authentication packet to the gateway (if needed). When you're finished, call nu_client_free to free the session.

Original packaging and informations and help can be found from


nu_client_init returns an authentication session usable by nu_client_check or nu_client_free.

nu_client_check returns the number of packets authenticated to the nuauth server during the call. It returns -1 if an error occur when sending authentication packet. Applications MUST considered that the session is unusable when they receive this error.


nu_client_init return NULL it a problem occur during initiation


Nufw was designed and coded by Eric Leblond, aka Regit (<[email protected]>) , and Vincent Deffontaines, aka gryzor (<[email protected]>). Original idea in 2001, while working on NSM Ldap support.
