Could it be reverse resoluton? What do you see when you do an nslookup
of the ip address?

Subject: DNS and export
Importance: High
There is a RS/6000 at one of our subsidiaries. On that RS/6000 is a
filesystem that they are exporting to 'everyone'. I can mount it
on some of my boxes but not many. Logging in on that remote system, I
see that only 3 or 4 of my systems are in the local /etc/hosts
file. Those are the only systems here that can mount that filesystem
from the remote server.
The RS/6000 is running AIX 5.1. It is an NIS Master Server. It is
running DNS
That is where my question comes. If I log in on that remote server
from a RS6k here that can NOT mount and do a "who", I see me
logged in and it shows my IP address rather than my hostname. But if
I do a ping of the box I am coming in from, it can resolve it
and pings that box at the IP address. If I do an 'nslookup' of the
hostname of the box I came in on, it finds it.
So, it appears that nfs export only works if the box is in the NIS
host file and does not go to DNS? But ping finds it in DNS and
proceeds as does other functions? Also, it appears that exporting to
everyone only works if the IP address of the requesting client
can be resolved?
What is wrong here.
Here is what is in the '/etc/netsvc.conf':
host = local,nis,bind
The '/etc/resolv.conf' has their nameservers followed by their domain.
After that is a 'search' line with their domainname. After
that is another 'search' line with my domainname. Should that be on
one line?
Any help would be great.
