Greetings,
My ISP has recently switched their protocols, and as I am moving, I will
be required to give up my static IP in favor of a dynamic one (they now
only offer static IP's to bunsinesses). In any case, I have been told
that they use the pppOE protocol. I know that some changes will be
required in my networking set-up and have been archiving as many posts
as I am able regarding this. However, my setup is a tad ... ~bizarre~
... so I would like some advice.
I'm running 2.2r5 (stable w/ 2.2.20 kernel and some third party progs),
that was upgraded from a slink (2.1?) StormLinux distribution. All
networking components are stable. I have also downloaded Roaring Penguin
pppOE in anticipation of the switch.
When I initially setup my system, my IP, netmask, gateway, etc were
placed ~in~ the script run from /etc/init.d/. (I've attached copies of
the scripts involved).
--- begin insert /etc/init.d/network
#!/bin/sh
cat /proc/net/dev |grep : | cut -d : -f 1 | grep lo >/dev/null 2>&1
if [ $? -eq 0 ] ; then
ifconfig lo 127.0.0.1
route add -net 127.0.0.0 netmask 255.0.0.0 dev lo
fi
IPADDR=10.169.239.186
NETMASK=255.255.255.248
NETWORK=10.169.239.0
GATEWAY=10.169.239.185
cat /proc/net/dev |grep : | cut -d : -f 1 | grep eth0 >/dev/null 2>&1
if [ $? -eq 0 ] ; then
ifconfig eth0 ${IPADDR} netmask ${NETMASK}
route add -net ${NETWORK} netmask ${NETMASK} dev eth0
[ "${GATEWAY}" ] && route add default gw ${GATEWAY} metric 1
fi
--- end insert
At the time, I upgraded from a network install, so this info was either
entered at that time, or later through us of linuxconf. My
/etc/network/interfaces script (following) has only the line for my
loopback, whenever I have tried to enter info for my eth0 directly in
this file, I receive errors about duplicate networking configs (no
surprise there).
--- begin insert
# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/netbase/examples for more information.
#
iface lo inet loopback
--- end insert
NOTE!!! I don't have either an 'ifup' or 'ifdown' script in the
/etc/init.d/ directory. I assume that networking is being handled
directly from the first script.
QUESTION - 1 !!!
My thought is that ~prior~ to installing my pppOE, I should rename the
/etc/init.d file so that it does not load, so that the only script
called is the /etc/network/interfaces script. Yes? No?
Also, as I will be using pppOE rather than dhcp, what changes will have
to be made to this file (if any). My box is rarely turned off, so I am
only concerned about my system coming up with ease whenever I am forced
to reboot (new kernel etc.).
QUESTION - 2 !!!
I will also no longer be forced to use the g*dawful hostname assigned by
my ISP, I would like to change my host (and domain) names to reflect a
future change in number of boxes and implementing of a home system. I
will eventually have a FQDN, but would like to use a version of that
now. Would a "home" or "sys" domain extension be appropriate or
conversely case problems? I have at least two files that contain my
current hostname (hostname and HOSTNAME); which should be changed.
I'm also assuming that those hosts should also be entered in my hosts
file to allow access to/from them.
I've also been assured by my ISP that my DNS entried will be unaffected
by the change (thanks for small favours).
Any help would be greatly appreciatoed.
