Description Craig Lawson 2002-09-23 04:14:45 UTC
Description of Problem: The timeouts for pppd and pppoe that are assigned by internet-druid interact negatively and insure frequent disconnects. The timeouts cannot be altered through either the internet-druid or neat interface. Version-Release number of selected component (if applicable): redhat-config-network-1.0.0-1 How Reproducible: 100% Steps to Reproduce: 1. Configure an xDSL interface with internet-druid. 2. Establish a connection using rp3 or adsl-connect. Be sure to use the configuration file created in step 1. 3. Don't use the network for about 20 seconds (might take longer). 4. Use "ps afx" to locate the adsl-connect, pppd, and pppoe processes. After some time, the process IDs for pppd and pppoe will have changed. If using the RP3 applet or another network interface monitor, the green "connected" light will turn black. Actual Results: After periods of inactivity, the connection will be dropped. It usually takes 20 seconds, but could take longer. Expected Results: The connection should be stable. Additional Information: internet-druid gives the same value to both the pppd echo interval and the pppoe timeout interval: 20 seconds. This causes a race condition where pppd issues an LCP echo request at the same time that pppoe decides to die because of inactivity. To avoid this problem, the pppoe info page advises against making these values the same, and suggests that the pppoe timeout interval be 4 times larger than the echo interval. The relevant values in /etc/sysconfig/network-scripts/ifcfg-(whatever) are: PPPOE_TIMEOUT=20 LCP_INTERVAL=20 Changing the PPPOE_TIMEOUT value to 80 solved the problem.

first beta of erratum is available at: ftp://people.redhat.com/harald/redhat-config-network/1.0.1-1/ Most of the bugs reported have been removed, but as in every software change, there could be new bugs introduced. Please report bugs against this with explicitly stating the 1.0.1 version... Thx and please test.
Comment 2 Craig Lawson 2002-11-13 00:27:15 UTC
I tested 1.0.3-1. This bug is fixed. Thanks!
