Hi,
The 2wire router from ISP Telmex Infinitum (Mexico) went on the blink so
they gave a new one. It's a Thomson TG585V8.
One thing that I noticed is that the external IP now changes about every
hour or so, when the internet goes offline and after a minute or so
comes online again.
The other thing is now I see:
Jan 7 10:09:08 HDBB dhclient: bound to 192.168.1.190—renewal in 55 seconds.
While previously I saw:
Dec 31 08:01:13 HDBB dhclient: bound to 192.168.1.190—renewal in 40438
seconds.
Why the difference?
That router has 2 systems connected to it, both with ethernet cable, a
laptop running Squeeze and a desktop running Sid.

Hey, we've got a bunch of TG585v7 (for ISDN lines) :-)

Maybe the time for the leasing has decreased with the new device, but I
guess this can be tweakable from the router's web interface (or by means
of telnet) :-?
Look, this is from the router's configuration page:
***
Home > Home Network > Interfaces > LocalNetwork [ Configure ]
DHCP Lease Time: 1 day, 0:00:00

but it is not configurable. And then I still see in syslog:
Jan 7 12:10:48 HDBB dhclient: bound to 192.168.1.190 -- renewal in 59
seconds.

almost one day), so maybe is your dhcp client which requests for a lease?
Look at "/etc/dhcp/dhcpclient.conf" file and search for any "lease"
stanza. If it is commented, edit accordingly to enable you can define
there your client settings.

short lease times for both devices have to do with the external IP changes.

Configured the TG585V8 with the only configurable item: "Always use the
same IP address" set to "yes" that sets "DHCP Lease Time: Infinite":
http://debian-oaxaca.blogspot.com/2012/01/blog-post.html
Then I did a new install of the Wheezy netinst.iso of today (Jan.7,
2012). Did not install any software, did not change anything, just the
base installation. Result: lease renewal every 56 secs. Weird.

External IP address changes should have no effect on your internal

That does seem like it should give your internal LAN devices the same
IP address each and every time and good forever.
That should have no effect on your router getting a new address often
from the external WAN dhcp server. That would be completely separate
and unrelated.

The new install of Wheezy will be unrelated to what your router
allocated for dhcp on the internal LAN. They are not related. Your
Wheezy install will ask your dhcp server for an address and it will be
assigned one along with a lease time. It can only work with what it
has been given. If your router is crazy then there isn't anything
that a Wheezy system, or any other, can do about it.
I would be inclined to look for a firmware upgrade for the router.
And then try to reset the state back to a default factory setting.
Then start again on changing the configuration. It really sounds like
something is wrong with the software on that router.

Mmm, you're using DynDNS...

But the external IP your ISP "assigns" to the WAN interface of your
router has nothing to do with the internal IP your routers "assings" to
the 4 LAN ports (you) :-)
Anyway, query your ISP about this because is not normal (at least not for
my provider) to have the remote IP changing every hour :-?

It should not be related at all. Look, my external IP remains the same
even when I power cycle the router, but the local DHCP lease is set to be
renewed every 9 hours.
I would try by enforcing the local lease time renew from the client side
(i.e., your debian computer).

Did you configure your "dhclient" to request a lease every 12 hours?

That options ("use the same IP") is not available for me. Have you tried
to disable?

Yup, it's not normal. But it can be a bug in the router's firmware that
makes it to behave weirldy. To start discarding culprits, I would try
with another DHCP server, if you have another device than can be
configured in that way.

My bad.
It was not the "lease" stanza what you had to edit. I overlooked the
"dhclient.conf" file but "man dhclient.conf" confirmed the lease is used
when the client cannot connect to an existing DHCP server, which is not
your case :-)
And from man page I can't see an option which you can configure from the
client side to define a renewal interval... hum.

you only have a router available you can install a DHCP server (or run a
LiveCD with DHCP server configured) in a separate computer... unless you
only have one computer in such case no DHCP server is needed at all :-P

Hugo... let's go debugging.
Open a console and type:
telnet 192.168.0.190
username: 1234 (type yours)
password: xxxx (type yours)
Then type:
dhcp server lease list ↵
And see what's the current TTL (Time To Live) value for the current
assigned lease (it should be 24 hours minus the time of the last renewal
request from client).
>From here (telnet) you can also configure the router's LAN DHCP settings:
dhcp server pool list (to display the current pool's name)
dhcp server pool config (to configure the pool)

one feature of the DHCP server which did not stick when it was configured
using the web interface)

so that I had to do a hardware reset to the box.
What specifically am I trying to reconfigure in that pool?

I did not quite show that right: this is what 'dhcp server pool config'
looks like:
_{TELMEX}=>dhcp server pool config
name = LAN_private
[state] = enabled
[allocation] = dynamic
[intf] = LocalNetwork
[index] =
[poolstart] = 192.168.1.64
[poolend] = 192.168.1.253
[netmask] = 24
[gateway] = 192.168.1.254
[server] = 192.168.1.254
[primdns] =
[secdns] =
[dnsmetric] = 0
[primwins] =
[secwins] =
[leasetime] = 86400
[state] = enabled
[allocation] = dynamic
[intf] = LocalNetwork
[index] =
[poolstart] = 192.168.1.64
[poolend] = 192.168.1.253
[netmask] = 24
[gateway] = 192.168.1.254
[server] = 192.168.1.254
[primdns] =
[secdns] =
[dnsmetric] = 0
[primwins] =
[secwins] =
[renewtime] = 60
[rebindtime] =
[unnumbered] = disabled
[localgw] = disabled
[localdns] = enabled
:dhcp server pool config name=LAN_private
{TELMEX}=>
[localgw] = disabled
[localdns] = enabled
:dhcp server pool config name=LAN_private
And there you see IMO where those renewals of 57 secs. come from:
'[renewtime] = 60'
Now I have to find a way to change that :-)

and so:

{TELMEX}=>dhcp server lease flush
{TELMEX}=>dhcp server pool config name=LAN_private renewtime=86400
{TELMEX}=>dhcp server config state=enabled
{TELMEX}=>saveall
{TELMEX}=>exit
Connection closed by foreign host.
and in syslog:
Jan 9 07:41:55 HDBB dhclient: DHCPREQUEST on eth0 to 192.168.1.254 port 67
Jan 9 07:41:56 HDBB dhclient: DHCPACK from 192.168.1.254
Jan 9 07:41:56 HDBB dhclient: bound to 192.168.1.190 -- renewal in
