Hello. My first e-mail seems very messed up, so I will try again. Sorry
about that, I hope this will be OK.
I encountered big problem after switching router from gentoo to freebsd.
It does not properly reconnect ADSL link after loosing connection, for
example, when ISP cycle IP address or when I pull out cable from ADSL
switcher for testing purporse. I cannot realize what's going on and
really need help.
First problem get when ISP disconnect me after 24 hours due to IP
change. Link does not properly get reconnected. ppp tries to connect,
and appearenty is connected, but something is wrong because no traffic
is possible and after few seconds ppp goes down and reconnects again.
And again and again.... Strange above all is that during reconnecting
routing table always has default route, but ping does not go. Next, I
will put some information that I think is relevant to problem, but it
seems to me, not very useful in debugging this.
During reconnecting as I describe above, this is my routing table:

No buffer space available??? What is that?
These are lines from log, where you can see that it reconnects and never
stops that

I tried lot of things. "enable lqr", "enable echo"... nothing helps.
Moreover, testing this by pulling out cable and replugging it give no
response from system! If I do that, link goes down (real link), but
system do not realize that at all! Routing table remains unchanged,
default route still is there, tun0 interface still configured, ppp runs,
and in /var/log/ppp.log there is no new single line after that
replugging cable into ADSL modem! How is that possible? Isn't pulling
out and replugging cable should be enough for ppp to realize it that
tun0 should be reconfigured and ppp redialed?
Of course, I start ppp as:
# ppp -ddial htnet
I really need reliable connection that needs no permanent monitoring by
myself and manually reconnecting after being dropped. Please, give me
some idea what can I do because I'm still desperate after few days of
trying to fix this. For sake of completness, I had no problems with this
before, on gentoo. Now I run FreeBSD 7.

If you think that some other messages from system will be more useful, I
will hapily provide them.
Thanks to all!
