When I attempt to ftp to a site (ex: mysite.ftpsite.com), I get an
"Unknown host" error. However when I use the actual IP address (i.e.
12.34.231.241), it goes through just fine. Where do I go to fix this?

The root user needs to set up a readable (644 or 444) file called
/etc/resolv.conf with two lines in it:

domain your.domain.name
nameserver XXX.XXX.XXX.XXX

You have to fill in your domain name and the numeric IP address of a
nameserver that your machine has a route to.

That is already set up and in fact has 777 permissions:



-rwxrwxrwx 1 root system 45 Jan 04 08:44 resolv.conf







I can ping my DNS from th UNIX box. Any ideas??

First, change it back to 644 or 444. AIX is funny sometimes about
permissions. Plus, there's no need to make that file executable.

What kind of error messages do you get if you type these commands?

nslookup yahoo.com
traceroute yahoo.com

Are there errors? Are there different errors if you do the same
thing with your "mysite.ftpsite.com" address from your original post?

Perhaps your DNS server doesn't know about "mysite.ftpsite.com". If
that is true, then you need to go after whoever maintains that
server.

As a last resort, define it in /etc/hosts and forget about DNS
resolution.

nslookup works fine for yahoo. Traceroute gives me this:



# traceroute yahoo.com

traceroute: unknown host yahoo.com





nslookup for mysite.ftpsite.com gives this:



Non-authoritative answer:

Name: mysite.ftpsite.com

Addresses: 197.153.155.81, 197.3.165.79





traceroute for mysite.ftpsite.com gives the same result as doing a
traceroute on yahoo.

What does "host mysite.ftpsite.com"

If nothing, then you've got a name resolution problem. Someone has
failed to add that host to DNS or /etc/hosts

FYI: That's bad security.

chmod 644 /etc/resolv.conf

to prevent group and others from rewriting that at will.

yahoo.com is not a host--it's a domain. Try www.yahoo.com

That's encouraging.

Now the true test is to use host instead of nslooup.

I'm guessing that
# host mysite.ftpsite.com

is not returning an answer. The question is "why?"

What's in /etc/netsvc.conf ?

This says one of the following is wrong: the NSORDER environment
variable, /etc/irs.conf, or /etc/netsvc.conf. That is, nslookup always
uses DNS for lookups. Other programs (e.g., traceroute) check to see
whether to use files or bind or nis or ldap or studying their belly-buttons.
Since nslookup works, DNS must be okay. Traceroute failing says you are
somehow telling the normal hostname lookup routines not to us BIND/DNS.

Docs for each of these configuration methods can be found by searching at
