Hello 9fans!

It seems to me the following codes are buggy.
		len = read(fd, buf, sizeof(buf));
		getactivity();  /* this line is added by the boddle 811708952 */
		err = convM2DNS(&buf[Udphdrsize], len, &reqmsg);
 in dnsserver() in ndb/dnserver.c

I think they should be:
		len = read(fd, buf, sizeof(buf));
		getactivity();  /* this line is added by the boddle 811708952 */
		len -= Udphdrsize;
		err = convM2DNS(&buf[Udphdrsize], len, &reqmsg);


We can find similar codes in dnresolve.c
		len = read(fd, ibuf, Udphdrsize+Maxudp);
		alarm(0);
		len -= Udphdrsize;
		if(len < 0)
			return -1;	/* timed out */
		/* convert into internal format  */
		err = convM2DNS(&ibuf[Udphdrsize], len, mp);

bind -a '#l1' /net
ip/ipconfig -b -e ether1 -m netmask ipaddress

look at the man page for ipconfig that came with the boddles.

Hi David,

Your multi-ether began to work.
By the way, how can I assign IP to the second card?

Thank you for your comments:

Oh! You are right.
There are two updated ndb codes!
ftp://plan9.bell-labs.com/plan9/update/ndb
and
ftp://plan9.bell-labs.com/plan9/update/cmd/ndb
I have discussed on latter.

Some comments on update/cmd/ndb will be required in the
directory.
