no network access to or from server
I'm faced with an issue that I don't understand; I hope someone can help me.
I have a dedicated server at 1and1.com that will be our company's new web
and mail server running Debian 3.1.
I have installed Postfix, Dovecot, and Apache2 to name a few, and everything
was working as expected and so I decided to try to install Shorewall and was
unable to connect to the box via the internet (at least I still have console
access) after following a how-to for a stand-alone firewall.
So, I decided I would remove the package and try something else instead.
Now, when I reboot the server I am unable to connect to the server from the
internet, or to the internet from the server. My eth0 interface does not get
configured with it's IP address (22.214.171.124).
I tried rebooting, and restarting /etc/init.d/networking to no avail.
What the heck went wrong that I can't bring up my interface now?
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
DHCP? Wtf? On a dedicated server? Shouldn't it be a static IP address?
1and1 Support said, yes, I had a static IP address. But that's as far as
they will help since I have a dedicated server. They said I am configuring
my interface wrong and they won't help, but that it works just fine when set
to dhcp....except in this case.
I tried to change the last line to the following (information provided by
1and1 tech support):
Iface eth0 inet static
I presume I should also add:
but they haven't volunteered that information when asked.
I must be overlooking something, but I can't figure out what it is.
Thanks in advance for any help provided.
