Yet further more information: This bug was not reproducible last night, which sucks. But I found a _new_ problem (I was debugging this over the phone, so I couldn't get a lot of information from the non-techie on the other end). With the appropriate configuration, doing a "ppp isdn", then a dial from within the ppp worked fine. But doing a "ppp -auto isdn" resulted in an error after doing a SIOCIAFADDR (I think). I don't remember the error string off-hand, unfortunately. This error happens sporadically when the connection is explicitly established with "dial", but happens _every_ time with "-auto", before a connection is actually made -- that is, it happens when ppp is trying to initialize the run interface (I assume), _not_ when it makes the ISDN connection. And yet it _only_ happens with the ISDN connection (which also has a different configuration due to a faster connection to the modem (115200), and a different ifaddr). I just had enough time to look through the PPP code and find the one place it occurred, but since it was only reproducible by my friend over the phone, I'm not sure how to easily debug this. So again, I'll ask if anyone has seen this. I haven't gotten much in the way of help with this stuff, so if you haven't bothered answering because you figure someone else has probably answered, please reconsider... Thanks for any help. Steven
