Re: Ping returning wrong address

[rob@xxxxxxxxx]

Where is this cache?  On the 400 or the DNS?  The Cisco kid said there was
a 20 min cache.  I waited longer than that.

Rob, I agree with Jeff. The AS/400 follows the standard when it come to
How Long to cache the DNS info for an address. Windows for example ignores
the time-out value and will Always do a look-up. When the DNS info is sent
to a computer, along with it is a value that tells the computer how long
to use its cached info for that address. The iSeries does what is told. If
the data time-out is set to 5mins or indefinitely that's what it will do.
Find out what the time-out is set to.

We have multiple IP addresses set up in our TCP/IP interfaces on this one
400.  Each Domino server has it's own.  Well the NT people here got cute
and used one of our IP addresses for one of our Domino servers and set
that
up in the DNS for the 400 itself.  10.10.1.186 is for the Domino server
GDSHELP.  10.10.1.123 is for the 400 GDIMAIL.  But I ping GDIMAIL from
elsewhere and it went to 10.10.1.186.  Well, I got the Cisco kid to fix
the
DNS.  Now when I ping GDIMAIL from my PC I get 10.10.1.123.  However when
I
ping GDIMAIL from another 400 it still goes to 10.10.1.186.  I checked the
host table on the source 400 and there is no GDIMAIL, no GDSHELP and no
10.10.1.186.  I checked out the address of the DNS using 12. Change TCP/IP
domain information and it matches the address of the dns from my PC.  So I
tried adding a host table entry for 10.10.1.123 to GDIMAIL.  Now when I
ping GDIMAIL it works.  I removed the host table entry and it goes back to
10.10.1.186.  Is there some sort of cache or am I missing something?

I'll probably leave the host table in for a workaround.
