Hello all,
First posting to the list. I'm a long time Gentoo user, but I'm playing
with my first Debian system since many years ago.
I've been considering a wholesale change to another distro (Debian and
FreeBSD being the top contenders) for some time now due to some of the
changes that have happened in the last year or two with gentoo (won't go
into details). I will soon be rolling out a new groupware system (SOGo)
that is not supported on gentoo or FreeBSD, so Debian (no way I'm going
RedHat) is the obvious choice for this new server - and since SOGo
doesn't officially support FreeBSD, I will most likely use Debian for
the new mail server as well.
I'll be posting a series of questions trying to get my head around the
differences between Debian and Gentoo. I will rtfm as much as possible,
but I have some questions that I need to address fairly quickly to get
this new SOGo server ready for implementation, so some of my questions
may seem lazy, but that will only be because time is short. Specific
answers are appreciated, but pointers to the docs are absolutely sufficient.
First question is, I have set the system to a static IP and restarted
the network service:
less /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
#allow-hotplug eth0
auto eth0
iface eth0 inet static
address ###.###.###.###
gateway ###.###.###.###
netmask 255.255.255.0
network ###.###.###.###
broadcast ###.###.###.###
service networking --full-restart
But, every 10-20 seconds, I'm seeing DHCP requests in the logs (they are
being blocked by the firewall - I'm paranoid, and implement both inbound
AND outbound rules):
Jan 3 07:12:30 sogo dhclient: DHCPREQUEST on eth0 to ###.###.###.### port 67
Jan 3 07:12:30 sogo dhclient: send_packet: Operation not permitted
Jan 3 07:12:30 sogo kernel: [12868185.930627] (fw>): IN= OUT=eth0
SRC=###.###.###.### DST=###.###.###.### LEN=328 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF
PROTO=UDP SPT=68 DPT=67 LEN=308
Jan 3 07:12:49 sogo dhclient: DHCPREQUEST on eth0 to ###.###.###.### port 67
Jan 3 07:12:49 sogo dhclient: send_packet: Operation not permitted
Jan 3 07:12:49 sogo kernel: [12868204.222463] (fw>): IN= OUT=eth0
SRC=###.###.###.### DST=###.###.###.### LEN=328 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF
PROTO=UDP SPT=68 DPT=67 LEN=308
Since I've configured eth0 for a static IP, why are these DHCP requests
even happening? I've looked in /etc/init.d and don't see anything about
a DHCP client. And most importantly, how do I stop them? I know I could
probably uninstall DHCP client, but that doesn't seem like the proper
solution.
Thanks
Charles
