i am confused. I have a USR modem that seems to be working fine.. and
a ppp setup that also seems to be working fine, however, when I
_send_ large amounts of data.. I get dropped. Receiving works fine.
At first I thought ti was a problem with the modem.. but after
flipping SW1 and telling it to ignore DTR, I find that the modem is
remaining connected. It is user ppp that is dropping.
I have read the FAQ/Handbook.. and checked the mailing lists. I have
disabled lqr ( config included below ), but after much testing .. and
much frustration on the part of my irc buddies watching me bounce all
day.. I cannot seem to find the answer. here is the relevent log
entries in the ppp.log:
Aug 27 15:26:54 hydra ppp[6848]: tun0: IPCP: deflink: LayerUp.
Aug 27 15:26:54 hydra ppp[6848]: tun0: IPCP: myaddr 209.96.185.74
hisaddr = 204.17.220.65
Aug 27 15:26:57 hydra ppp[6848]: tun0: Phase: deflink: Carrier lost
** This is ALL i get at close time **
Aug 27 15:26:57 hydra ppp[6848]: tun0: CCP: deflink: State change
Stopped --> Closed
Aug 27 15:26:57 hydra ppp[6848]: tun0: CCP: deflink: State change
Closed --> Initial
Aug 27 15:26:57 hydra ppp[6848]: tun0: LCP: deflink: LayerDown
Carrier is set to override both in the modem and in the config
string.. so I am rather baffled. My test involves scp'ing some files
to a host on the net. As soon as it gets x distance into the copy it
dies, consistantly at the same spot. This tells me it is probably a
buffer problem somewhere.. but I havn't a clue.
If anyone could be of assistance.. i would appreciate it. thanks in
advance.
