Samba default configuration file is bad, because it suggests to enable SMB on all interfaces. That is bad for ppp* : your Internet provider do not care of Samba That is bad for irda : (maybe a bug) it breaks IrLAP connection. So, suggest lo (mandatory) and eth0 (used by most people) ; interfaces = lo eth0 ; bind interfaces only = True or ; interfaces = lo eth* ; bind interfaces only = True
