Modem Connection Terminates Shortly After Dial-Up

Support knowledgebase (thallma_lcp_echo)
Applies to

SuSE Linux: All versions

Symptom

Your Internet connection via modem seems to work, but the connection is interrupted shortly after the dial-up connection has been successfully set up. The following error message is displayed:

--> pppd: Terminate Request (Message: "Peer not responding")
--> pppd: Connect time 2.1 minutes.

Cause

Your provider does not react to the LCP echo requests sent by your system. These requests are sent by the Linux system and must be responded within a given time. Your system uses this command to check the availability of the remote host.

Having taken this information into account and understandably enough, the Linux system (or better said, pppd) hangs up after a short time.

Solution

In order to keep an Internet connection with your provider under Linux, this process, which is correct in itself, must be disabled. Please open the file /etc/ppp/options as root user with any ASCII editor of your choice, and delete the lines:

lcp-echo-interval 30
lcp-echo-failure 4

Save the modified file and retry to establish a dial-up connection.

Note: The problem is mostly on the provider's side and not on the Linux system's side. The provider's dial-up host is either too overloaded to respond to the LCP echo requests, or its configuration does not comply at all with the PPP Internet connection standards.
