pppd[n]: tcflush failed: Input/output error

[musasabi]

well, this is the error i get from pppd when attempting a connection to my local college's dialup service.

tcflush failed: Input/output error

i dial in, it does all of the audible handshaking, and then it waits for a long time, and i pppd dies with that error.

whats relatively peculiar is that sometimes it works and sometimes it doesnt... for a while, i was able to attempt a connection, wait a few minutes after it failed, attempt again, and have it succeed.

I am not sure of this solution.....though you can give it a try.
Just check the authentication protocol, it should be PAP or CHAP or something of some sort if the ppp dies.... Not sure

[musasabi]

well, for the sake of information, its PAP.

thing is though, im using the kppp front-end, and it has a PAP/CHAP option. so i was using that. you'd think that that would allow both to function, but ya never know.

ill go try it and edit this post accordingly.

EDIT: nope, no go. haha. actually, it worked once. i disconnected and attempted a reconnect and it gave me the same error. maybe i should just switch protocol options every time i reconnect? :P
