Hello,
I'm running diald version 0.16.5 on a Debian 2.1 system.
I'm experiencing a strange problem that may be a diald bug.
My dialup connection is started by a ping packet, that diald
accepts by a
rule with a 60 seconds timeout.
After only 5 seconds, diald receives from the remote host a
packet that is
ignored because no rules matches it. Just after this, diald close
the
connection stating: "Closing down idle link".
Why the "Adding connection" message does not have the
corresponding
"Deleting connection" in the log and why the 60 seconds timeout
is not
respected?
The line is an ISDN, the remote host is a Sun Solaris (I think),
which sends
to my system a lot of packets to the address 224.0.0.x, which I
have to
ignore otherwise the line never goes down.
I made some experiments: it seems that if I send some other
packets AFTER
the one that started the connection, but BEFORE I receive any
packet from
the remote host, then the timeout is respected.
The rule (# 42) that accepts the ping packet is:
accept icmp 60 any
Here it is an excerpt from the log:
