I am trying to get THNX ready for IWP9 and I have a problem I don't
understand. Almost everything works on the net save dns. In fact I am
drawterm'ed into it across the net from another box, that's how I got
the text from below.

I am bringing up the Plan 9 guest and it is succeeding at DHCP. The
router/dns/DHCP box is at 192.168.18.10.

Here is my iproute
cpu% cat /net/iproute
0.0.0.0         /96  192.168.18.10   4    none   -
192.168.18.0    /120 192.168.18.0    4i   ifc    1
192.168.18.0    /128 192.168.18.0    4b   ifc    -
192.168.18.190  /128 192.168.18.190  4u   ifc    1
192.168.18.255  /128 192.168.18.255  4b   ifc    -
127.0.0.0       /128 127.0.0.0       4b   ifc    -
127.0.0.1       /128 127.0.0.1       4ip  ifc    0
127.255.255.255 /128 127.255.255.255 4b   ifc    -
255.255.255.255 /128 255.255.255.255 4b   ifc    1
cpu%

and /net/ndb:
cpu% cat /net/ndb
ip=192.168.18.190 ipmask=255.255.255.0 ipgw=192.168.18.10
	dns=192.168.18.10
	dns=146.246.250.1
cpu%

BUT: /lib/ndb/local is this:
ipnet=lguestnet ip=192.168.19.0 netmask=255.255.255.0 ipgw=192.168.19.1
	proto=tcp cpu=lguest fs=lguest auth=lguest authdom=lguestdom
	dns=192.168.19.1
sys=lguest ip=192.168.19.2 dom=lguest authdom=lguest  auth=lguest

The problem: no DNS. Snooping from the linux and plan 9 side shows no
packets go to 192.168.18.10 for dns requests. Is the /lib/ndb/local
misdirecting dns somehow? I hate to yank the /lib/ndb/local, however,
as it is useful when the plan 9 guest is running in NAT as opposed to
BRIDGE mode.

The cpurc is this:
ip/ipconfig ether /net/ether0
date > /env/boottime

# replace FILESERVER with the name of your file server
# here we start with kfs, your local disk file system
fileserver=kfs

# replace FACEDOM with the local domain to be used in the faces database
facedom=FACEDOM

# mount points
mntgen -s slashn && chmod 666 /srv/slashn

# name translation, cs sets /dev/sysname
ndb/cs
sysname=`{cat /dev/sysname}
ndb/dns -r

and the sysname is this:
cpu% cat /dev/sysname
192.168.18.190cpu%

I am not sure I see what's up. I can't run acid on this (one of the
issues with the lguest port still :-)

dnsdebug just sits there and appears to time out.

any help greatly appreciated.

thanks
