Switching from dial-up to high speed

Post by Dave Yeo
Am I correct in assuming that if I plug my computer (both Warp v4 and
eCS 2.1) into a router connected to the internet that DHCP will just work?

If it is a /router/ then you are right.
But if it is /not/ a router and needs something like PPPoE, then things
get more complicated.

I bought a Netgear router/ADSL modem some year ago. Signed an ADSL
contract with one provider, configured the router, configured OS/2 to
connect to it and use it as a gateway. The only little trouble I had
was with the DNS server (I had to save them into the router and OS/2
configuration): since then it all works like a charm (and often better
than the other systems).

BTW, I don't use DHCP, preferring fixed IPs on my lan.

In theory yes, in practice it will depend on what your ISP supplies.

If it is ADSL and your ISP supplies a USB modem then it will need to
be changed - I've yet to find a way of using a USB modem with OS/2.
On the other hand, if they supply a modem/router then yes it will work
and you don't have to be concerned with whatever they use on the WAN
side.

Most modem/routers are set to provide DHCP as default, all you have to
do in that situation is set your OS/2 box to accept DHCP.

It's wireless, dish pointed at local mountain to receive a 800 Mhz
signal. I've the ISP supplies a router and it uses standard DHCP.
I take it I just turn on DHCP in the TCP/IP configuration notebook?

That should do.

That sounds something like my friends satellite setup.

Yes, you just turn on DHCP in TCP/IP, reboot and you should be away.
You can also use DHCP Monitor to check what IP address you get and how
long the lease lasts.

I have found it is the easiest way to get everything set up the first
tim when moving from a fixed IP to DHCP.

You can also write a script that will clear routs etc and reset them
as necessary.

I use this script (below). It's also useful when switching from an
ethernet connection (at home) to a WiFi connection on a totally different
network (e.g. at work) without having to reboot.

Requires PR1UTIL.DLL by Paul Ratcliffe, although it's possible to remove
that requirement with a little rewriting.

* Deactivate all IP interfaces and flush the routing and arp tables. This *

Why would you want to remove such a fine utility library? :-)

Not really. After changing the settings, just run setup.cmd from CMD.

It is better to close your mouth, and look like a fool,

Huh? Where is this CMD directory? I don't have it in my OS/2 boot
partition.

I know that Pete, it is just that some people are not very precise in
their wording. That also only works if MPTN\BIN is before some other
directory that has a setup.cmd in config.sys.

Ask them if it works with Linux without having to do anything special other than
having an ethernet card? Linux support is somewhat more widespread and "OS/2" is
more likely to elicit "what?" than anything else :-)

I questioned them last year when they had a series of community meetings
to decide whether to serve us. There's about 200 households in the
community and they had to decide if enough people would sign up to make
it worthwhile. The signal will go about 30 miles to a local mountain top
where they had to get permission to put a retransmitter with solar and
wind power, get converted to 800 Mhz and aimed at our area.
Unluckily they pulled a no-show yesterday.

Yes. And after you've done that, you should modify
\mptn\bin\setup.cmd to this:

dhcpstrt -i lan0 -d 0 (if you are using the first lan connection to connect
to the internet)

That will save you from a "press Enter to continue" on bootup should your
DHCP server (that is: your router) fail to assign an IP address in time. See
help for dhcpstrt.

There is also something to tweak in %ETC%\dhcpcd.cfg but normally it's not
necessary to touch it.
Just report if you are having problems. It also depends on the version of
dhcpcd.cfg that is installed on your computer if you have to touch it or not
(Warp 4 tends to have an outdated version of this file and then your DHCP
will not work. But in that case you most likely find a valid version as
mptn\samples\etc\dhcpcd.cfg).
With %ETC%\dhcpcd.cfg you can for example enable logging of all that DHCP
exchange which can help if something does not work out alright.
