Is this needed any more, since september I have not included this or any
client ID or similar in my dh configurations. I am also using pump quite
happily.

Bad bad bad. So very bad. *shudder*

Personally and correct me if I am wrong guys, I would trim this line to:
subnet 211.28.173.0 netmask 255.255.255.0 { }

I know it sounds silly, but check your MAC address's. Its amazing what a few
changes and swaps of NIC's can do to a network which relies on MAC related
IP assignments.

auto lo eth0 eth1
iface lo inet loopback

iface eth0 inet static
   address 192.168.103.10
   netmask 255.255.255.0

iface eth1 inet dhcp
    hostname hermes

Try putting the static ip's before any DHCP, some configurations I have seen
have been fickle this way. I don't for the life of me know why.

Doubt it.

SOP afaik.

Though one question. Why does DHclient list Eth0 as the ethernet you wish
you gain an IP for, and in /interfaces you have Eth0 as your static IP and
Eth1 as your dynamic ? Drop dhclient, use pump. My recommendation. Or change
your client conf.
