nslookup but no ping?

[allen_at-atoka <linux atoka-software com>]

hello:

i am having trouble getting my "complete" network access set up. i have a os/2 warp server connected to
the internet, with a linux client. the files that are relevant (i think???) on the linux machine have the
settings listed below. as can be seen, i can do nslookup's but not ping (nor get mail, ftp, telnet, etc).

/etc/hosts
127.0.0.1	localhost
192.168.10.1	archeozoic.mydomain.org	archeozoic #nameserver

/etc/dhcpc/ntp.conf
/etc/dhcpc/ntp.confserver 192.168.10.1

/etc/dhcpc/resolv.conf
domain mydomain.org
nameserver 192.168.10.1

/etc/host.conf
order bind,hosts
multi on

/etc/sysconfig/network
NETWORKING=yes
FORWARD_IPV4="yes"
HOSTNAME="jackfork.mydomain.org"
NISDOMAIN="mydomain.org"
IPX="no"
IPXINTERNALNETNUM="0"
IPXINTERNALNODENUM="0"
IPXAUTOPRIMARY="on"
IPXAUTOFRAME="off"
GATEWAYDEV=""
GATEWAY="192.168.10.1"


if i do a nslookup on some arbitrary domain, say mit.edu, i get the following results:

nslookup mit.edu
Server:  archeozoic.mydomain.org
Address:  192.168.10.1

Non-authoritative answer:
Name:    mit.edu
Address:  18.72.0.100

on the other hand, if i try to ping the same domain, event though it figures out it's address, it will
not successfully return a reply:

ping mit.edu
PING mit.edu (18.72.0.100): 56 data bytes

--- mit.edu ping statistics ---
9 packets transmitted, 0 packets received, 100% packet loss

as way of example, i do the same thing for one of the machines on my local network (i don't have to put
the fully qualified host name for this to work!):

nslookup crystalmtn.mydomain.org
Server:  archeozoic.mydomain.org
Address:  192.168.10.1

Name:    crystalmtn.mydomain.org
Address:  192.168.10.2

ditto for a ping of the same machine (i don't have to put the fully qualified host name for this to
work!)

PING crystalmtn.mydomain.org (192.168.10.2): 56 data bytes
64 bytes from 192.168.10.2: icmp_seq=0 ttl=255 time=0.5 ms
64 bytes from 192.168.10.2: icmp_seq=1 ttl=255 time=0.5 ms
64 bytes from 192.168.10.2: icmp_seq=2 ttl=255 time=0.5 ms

--- crystalmtn.mydomain.org ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0.5/0.5/0.5 ms

if i do a list records request to nslookup for my domain, i get the following:

nslookup -d mydomain.org
*** No address (A) records available for mydomain.org
;; res_mkquery(0, 1.10.168.192.in-addr.arpa, 1, 12)

another example is:

nslookup

Default Server:  archeozoic.mydomain.org
Address:  192.168.10.1

ls -d mydomain.org

any ideas would be most appreciated. (pardon my long windedness: i new at this networking task; i am not
sure what would help elucidate the problem.

by the way, pinging from archeozoic (nameserver, machine with direct connect) has no problem.
