Debian's dhcpcd .70-5 deb pkg wasn't working with my Intel eth0
and potato kernel 2.1.125 so I couldn't get a DSL account. Now I'm set,
thanks to Sergei Viznyuk. /etc/dhcpc/ has a file written by dhcpcd
which has my IP and the DNS nameserver assigned by ISP.

To get your IP assigned dynamically as by dial-up or ADSL or
cable modem, and to find out nameserver IP's--it's also necessary
to upgrade dhcpcd for kernels 2.1.125 and up, and for certain
netcards such as Intel--

ftp://phystech.com/pub

get the latest dhcpcd dhcp client by Sergei Viznyuk [applause, cheers]
which today is 1.3.17-pl2

untar ungzip cd

make ;  make install

Now you have /sbin/dhcpcd

Get your old dhcpcd out of the way--it was /usr/sbin/dhcpcd

In Debian it seemed logical to load dhcpcd using /etc/init.d/network
script--
most of this varies according to site-- "dhcpcd -h username" wasn't
working
from /etc/init.d/dhcpc script's line using start-stop-daemon, so--

#! /bin/sh
PATH="/bin:/sbin:/usr/bin:/usr/sbin"
ISP_USER_ID=username
ifconfig lo 127.0.0.1
route add -net 127.0.0.0 netmask 255.0.0.0 lo

if dhcpcd -h $ISP_USER_ID -d eth0 ; then

  echo -n "DHCP succeeded..."
  logger  "DHCP succeeded..."
else
  echo -n "DHCP failed..."
  logger  "DHCP failed... "
  IPADDR=192.168.1.2
  NETMASK=255.255.255.0
  NETWORK=192.168.1.0
  BROADCAST=192.168.1.255
  GATEWAY=192.168.1.1
  ifconfig eth0 ${IPADDR} netmask ${NETMASK} broadcast ${BROADCAST}
  route add ${NETWORK} famlan
  [ "${GATEWAY}" ] && route add default gw ${GATEWAY} metric 1
fi
