Hi,
I am running SuSE 6.2, kernel updated to 2.2.15, diald 0.99.4, external 56K
modem.
This was running very well for months (starting with diald 0.16.5) but since
a few weeks, the modem dialup is not working reliable. A typical
unsuccessful attempt looks like this :
linux01 pppd[4537]: LCP: timeout sending Config-Requests
With debugging on:
May 31 18:45:39 linux01 pppd[748]: pppd 2.3.8 started by root, uid 0
May 31 18:45:39 linux01 pppd[748]: Using interface ppp0

May 31 18:46:06 linux01 last message repeated 9 times
May 31 18:46:09 linux01 pppd[748]: LCP: timeout sending Config-Requests
but the following redial attempt might then be successful like this:
May 31 18:46:48 linux01 pppd[759]: Using interface ppp0

The last 2 attempts were just in a row, no definition changes or any daemon
restarts in between. I wonder whether it's something at the ISP's site?
(Apparently, they are not very knowledgeable with Linux/Unix at all.
Officially it's not supported ... but it was working perfect for months).
I have tried updating pppd 2.3.11 in the meantime, no difference. I also
tried other changes like increasing the amount of LCP requests
(lcp-max-configure 20), changing mru size, etc. to no avail.
Is there anything that I can trace at that stage? As far as I understand, I
can't use i.e. ethereal for debugging purposes before there is an
established connection on ppp0?
Any help would be much appreciated.
I am stuck here.
Kind Regards,
Michael Doerner
