By the way, because my cable modem is always on, it has the effect of
giving me a static IP address. Every so often, I force a new IP address.
Hm. My ISP (Belgacom Skynet of Belgium; what is yours if you don't mind
sharing the info?) disconnects me forcibly whenever my modem has been
connected continuously for 36 hours (± 1 second). At other times (in
practice rarely) I may of course get a new IP address by turning the DSL
interface off then on from a root console prompt.
Best regards,
Tony.
My cable modem is connected to Road Runner, a unit of Time Warner Cable.
It has no on/off switch. Even when my PC is powered off, the modem is
still connected to the Internet. To disconnect it, I have to pull the
plug on the power cord or physically disconnect the cable.
Road Runner said I should get a new IP address if I disconnect for at
least 15 minutes. Alternatively, they suggested the use of ipconfig,
for which I created the following DOS script:
chdir C:\WINDOWS\system32
ipconfig.exe /all
Pause "Old IP"
ipconfig /release
ipconfig /renew
ipconfig.exe /all
Pause "New IP"
However, to run this script, I have to connect my PC directly to the
modem instead of connecting through my router. The router creates a LAN
for my PC and my wife's PC. I tested this, and the script was not
effective while my PC was connected through the router to the modem.
Doing anything with the router or modem is a bother. They are in an
attic storage area that I can reach only if I move my printer stand.
Aha. My modem has no on/off switch either but it is at one end of an
Ethernet cable (one meter long maybe) whose other end plugs into my
"floortop" PC. No router (and no wife — for better or worse, I'm
celibate). So (under Linux and in a root console)
ifdown dsl0
ifup dsl0
and optionally (before and/or after)
ifconfig
is enough for me to get a new IP address. Quite similar to what your
script does, after one allows for differences between Windows and
Unix/Linux. And I don't have any attic — each apartment here (or should
I say each flat?) is one not very big floor, the attic is used by a
cellphone relay station (which radiates mostly in a horizontal plane,
I've had the radiation measured in my apart to make sure it doesn't leak).
Have a Merry Christmas and a Happy New Year
Tony.
