RE: long FTP connect on hosts not in DNS

It seems to me that C is trying to resolve B's address or is doing a reverse
lookup. My guess is this is a DNS-problem. Add B to C's host table. The
delay will probably be away.

Subject: long FTP connect on hosts not in DNS

Hi,

I've been using Red Hat 6.1 for a while and
haven't noticed the following peculiarity until now.

Let's say I have 3 hosts: A, B, C
B is on subnet 192.168.1.0 and 192.168.2.0
A is only on subnet 192.168.2.0
C is only on subnet 192.168.1.0
A and B are in the DNS (using net 192.168.1.0)
C is defined in B's host table as (IP C's FQ Hostname)
  A B C
  |_____| |____|

If I ftp from A to B, everything is fine. But when
I ftp from C to B, the server doesn't let me login for
about 25 seconds or so. The strange thing is that telnet
is without this latency.

My /etc/resolve.conf on host B has:
search mitre.org
<1st DNS IP>
<2nd DNS IP>
<3rd DNS IP>

I'm also running the latest Red Hat wu-ftpd.
wu-ftpd-2.6.0-1

Thanks in advance,
Tuan
