Support knowledgebase (hoe_tango1000_pppd)
Applies to

SuSE Linux: All versions

Symptom:

You want to set up a connection to the Internet. After the successful dial-in, the PPP daemon (pppd) is started but it aborts after a few seconds.
The file /var/log/messages contains status signals similar to

Dec 24 00:00:23 earth pppd[666]: sent [LCP ConfReq id=0x1 ]
Dec 24 00:00:23 earth pppd[666]: rcvd [LCP ConfAck id=0x1 ]
Dec 24 00:00:26 earth pppd[666]: sent [LCP ConfReq id=0x1 ]
Dec 24 00:00:44 earth last message repeated 6 times
Dec 24 00:00:45 earth pppd[666]: Hangup (SIGHUP)

Cause:

The cause is still unknown.
It seems as if the terminal adapter is reset or blocked through one of the received asynchronous characters and it no longer transmits data.

Solution:

Insert the following line in the file /etc/ppp/options:
default-asyncmap
