Yagishitia-san,
=20
This message is due to our inappropriate use of 192.167.x.x, which is
outside of the RFC1918 private address spaces; it is, in fact, owned by
Naples University.  There is an old bug filed for this design issue.  We
use the address range internally (see our Networking FAQ:
http://wiki.onstor.net/wiki/Networking_FAQ).
=20
Given these messages, I am concerned that our system may actually be
trying to contact the University IP addresses.  I recommend filing a bug
requesting that we make sendmail ignore this address range.

Hi

My customer find the strange message in the maillog of syslog(system_get
_all).

=20

[part of maillog]

Feb  8 04:00:21 bobcat3 sendmail[2355]: sm_gethostbyaddr: Lookup of
192.168.10.104 returned bobcat3.sc1=20

Feb  8 04:00:21 bobcat3 sendmail[2355]: sm_gethostbyaddr: Lookup of
192.168.11.104 returned bobcat3.sc2

Feb  8 04:00:21 bobcat3 sendmail[2355]: sm_gethostbyaddr: Lookup of
192.167.11.1 returned dns.dma.unina.it=20

Feb  8 04:00:22 bobcat3 sendmail[2355]: sm_gethostbyaddr: Lookup of
192.167.4.1 returned VS_MGMT_1537

=20

I know "192.167.xxx.xxx" is our backplane interface(192.167.vsID.vsIF).
The customer has 11 vsvrs on their cluster. Therefore,

"192.167.11.1" should be displayed in maillog. My customer worry that
"192.167.11.1" is address of Naples Univ. Certainly, "Lookup of
192.167.11.1 returned dns.dma.unina.it" is displayed.

My customer ask me

1)       Is this inquiry to dns.dma.unina.it normal behavior?  **They
don't think so.

2)       Is this done the hard court?

3)       Is this inquiry to dns.dma.unina.it every time?

4)       If dns.dma.unina.it down, is it no good for bobcat? Does it
cause trouble/error to bobcat?

=20

Thanks for your support.

Shun
