Hallo Martin,
Zur Lösung der ersten Aufgabe einige Tips :-)
(Ehrlich, ich war nie Lehrer ...)
Da Du auch das PPP Paket installiert hast, hast Du auch vermutlich
den bisdnd gepatcht. Dadurch hat er die Fähigkeit verloren, auf
Telefonanrufe zu antworten. In bisdnd/support.c muß es heißen:
int
connected(accept_t **accept_pp, int isdnfd, int atyp, int appl_no, int chan,
int active)
{
accept_t *accept_p;
int ret;
switch(atyp)
{
case ATYP_IP:
accept_p = connect_ip(appl_no, chan, active);
ret = GOOD;
break;
case ATYP_PPP:
accept_p = connect_ipp(appl_no, chan, active);
ret = GOOD;
break;
#ifdef NOTDEF
case ATYP_TTY:
accept_p = connect_tty(isdnfd, appl_no, chan, active);
ret = GOOD;
break;
#endif
case ATYP_TEL:
accept_p = connect_tel(appl_no, chan, active);
ret = GOOD;
break;
default:
accept_p = NULL;
ret = ERROR;
break;
}
Der Fall ATYP_TEL ist aus irgendeinem Grunde verlorengegangen und
muß wieder eingefügt werden.
Hier eine Beispielkonfigurationsdatei für den "Anrufbeantworter":

Wenn alles richtig installiert ist, und BISDN über Deine Inhouseanlage
funktioniert (das muß nicht so sein!) kannst Du bisdn anrufen und
er sagt Dir dann was. Wenn er nichts sagt, lohnt es sich bisdntrc
zu starten, um den Fehler einzukreisen.
Viel Erfolg
Wolfgang
Uebrigens, haben die patches von bisdntest-2 funktioniert? Wenn
/usr/include/machine keinen symbolischen Link auf /sys/i386/include
hat, sondern ein ``echtes'' Verzeichnis ist, mußt Du noch bisdn_ioctl.h
und bisdn_isdn.h von /usr/include/machine nach /sys/i386/include
kopieren und dann `sh mkbisdnkernel' aufrufen.
