This is what I had to do with my PPPoE ADSL link to Centurytel. I have about 15 minutes of downtime per day with them. They just disappear. Centurytel's equipment sends ECHO LQR requests but ppp doesn't seem to care if those stop coming in. My connection just stayed down until I added the LQR requests to my ppp.conf: enable lqr set lqrperiod 30 Now my ppp.log shows my router box redialing and not seeing any PPPoE traffic (or carrier?) for 5 to 30 minutes after the LQR monitoring dies. At least they usually do come back up. -- Scott Lambert KC5MLE Unix SysAdmin -- Looking for work. lambert@lambertfam.org http://www.lambertfam.org/~lambert/resume.html 2.5 years Sr. SysAdmin experience with FreeBSD in small & medium size ISPs.
