VL4.0 machine registers wrong name in my DNS

Hi!

I just installed Vector Linux 4.0 on my beloved/hated P133 machine. There were some "issues"

where I disagreed with the configuration, but I seem to be getting my way on most stuff now. There is however one thing that still annoys me:

The machine registers wrong name in my DNS! It doesn't register hostname, but (I believe) the MAC address from the nic. If I type

Code:

~> hostname
crap

I get the correct answer, but in my DNS it's

Code:

~> nslookup -sil 172.24.85.1
Server:         172.24.85.254
Address:        172.24.85.254#53

1.85.24.172.in-addr.arpa        name = 0100C0DF5098B9.homenet.

That alias is worse than the IP! Where is this configured? Somewhere around dhclient, perhaps?

Regards
Martin

Edit:
Sorry, forgot this information. My home network uses dhcp to assign addresses. And both my Redhat machine(s) and my Windows machine can register useful names in the DNS.

Hi again!

I found the reason. There seems to be a bug in the script that brings up eth0. If you experience the same problem, then you may want to change the script '/etc/rc.d/rc.inet1'. There was a missing '-h' option to dhcpcd.

Code:

...
# OK, time to set up the interface:
if [ "$DHCP" = "yes" ]; then # use DHCP to set everything up:
  echo "Attempting to configure eth0 by contacting a DHCP server..."
  /sbin/dhcpcd eth0 -h `hostname` # <-- CHANGED HERE!
elif [ ! "$IPADDR" = "127.0.0.1" ]; then # set up IP statically:
...

I have reported this as a bug on Vector Linux' own forum.

Martin
