Yep, it would be sad if a client could reset a server. :(

depending on how it is configured would still
retain the lease information.. and might refuse to give me another lease
because it thinks I already have one (?) And since I have no access to
my ISP's dhcp server configuration I cannot verify the above assumption.

Well, a new requirement.
Doing a
man dhclient
would suggest you could release the assigned ip addy.



Debian sarge and etch. The sarge system has never had any problems
connecting. The etch system, otoh, practically never connects
successfully.. Except that the other day I left it up overnight.. ran
dhclient manually in the morning and immediately obtained a lease.. eth0
and the route table were correctly configured and I was able to go
online. So my guess since I had changed nothing in my setup is that for
some reason my isp's dhcp server having heard nothing from me for a
number of hours decided to reclaim my lease.

Once you get a lease, your box is supposed to renew it based on renew,
rebind, expire times in the dhclient*.leases file.


This is all guesswork as I have really no knowledge of dhcp.. but I
would imagine that the server would keep track of which machines/nic's
he has already provided with and ip address and might would turn down a
new request from a machine with a currently active lease..

I have no direct knowledge about a server, but, I know I get the same
IP address from my ISP, regardless if I released the IP address or not.

And that would explain why I am practically never able to bring up the
connection.

Only if your log show the request refused. :)

Are the errors, dropped, overruns, frame faults pretty clean
