Weird Ping
I just pinged an .org address, and look at what I got:
====
[blinky@thurston ~]$ ping erwm.org
PING erwm.org.blinkynet.net (209.86.66.94) 56(84) bytes of data.
--- erwm.org.blinkynet.net ping statistics ---
13 packets transmitted, 0 received, 100% packet loss, time 11996ms
====
Why the heck would ping append *my* domain to the one I requested?
I immediately pinged another domain and that worked as usual.
Note that erwm.org was not found, but I don't recall failures behaving
that way before.
I just retried the .org ping to see if this was consistent and got the
same result. Was I just sleeping through this kind of response in the
past?

=============================================
I tried the above as well :
[frank@localhost ~]$ host 209.86.66.94
94.66.86.209.in-addr.arpa domain name pointer elydm.05.am.barefruit.com.
[frank@localhost ~]$ whois 209.86.66.94
bash: whois: command not found
[frank@localhost ~]$
Also there is no man whois
How to invoke whois ?

Well, the answer to your _question_ is, a
$ type whois
whois is /usr/bin/whois
would suggest that if /usr/bin is in your path,
$ echo $PATH
then doing a
whois ip|name_here
would invoke whois.
Now, the answer to your /problem/ is, click up a terminal
su - root
urpmi --wget whois --auto
exit
whois 209.86.66.94

Each server has it's dns server list. When the resolver can not find
the item, it hands off the request to the next DNS.
You have dns ip addresses in your /etc/resolv.conf.
You might have them your router/firewall.
Your ISP has local dns servers they tell customers to use.
Your ISP has global dns servers anyone can use to find the ISP
machines/customers
Then dns resolutions go up the chain until it comes back down to the
service provider who realy knows the target ip/FQDN. It returns the
requested information back to you.

Long story - short answer is you told it to. Man resolver, and look at
the "search" directive. (Also look at the "domain" directive, both of
which can cause some really strange results as you show here.) Then
fix your /etc/resolv.conf file as needed.
[color=blue]
>I immediately pinged another domain and that worked as usual.[/color]
OK
[color=blue]
>Note that erwm.org was not found, but I don't recall failures behaving
>that way before.[/color]
The domain exists (registered a couple days ago), but the name server that's
supposed to be authoratative isn't responding.
Ah, and that exposes another problem somewhere.
What happened is that your resolver tried to look up 'erwm.org', and got
a NXDOMAIN answer from the name server you asked. Your resolver then
followed your directions, and tried again asking about the original
name EXPANDED with the results of the 'search' or 'domain' name. Now
whoever is running the DNS for blinkynet.net may have a wild-card
in the zonefile (if the name doesn't match anything, return "this"
value) and somehow that answer came back as 209.86.66.94, which you
then pinged (use the -c option to cut down the number of pings), and
that host isn't responding to a ping.
So, 1) fix the /etc/resolv.conf file, and 2) ask who ever is running
the DNS server for 'blinkynet.net' WTF.
[color=blue]
>Was I just sleeping through this kind of response in the past?[/color]
Hard to say - when did you change /etc/resolv.conf, and when did the
zone file get mucked with? I just tried 'erwm.org.blinkynet.net'
here, and the result is the proper NXDOMAIN, so maybe the wild card
has been fixed.

In addition to the above, I note you tried ping erwm.org

Actually, it wasn't ping - it was the resolver code in the kernel

This is also an example of the security problem that the two multicast
DNS (microsoft got RFC4795 adopted as an INFORMATIONAL RFC, but an
incompatible competing version from Apple - included in some Linux
distributions as "Avahi") opens up for. You ask for the address of
your_bank.com while unable to reach a name server, Avahi then trys
a multicast DNS query for your_bank.com.the_domain_in_the_search.line)
and some cracker's box responds with "that.is.my.address" and they
may now have your username and pass-code. Not a good deal.
[color=blue][color=green]

or more likely, no response at all
[color=blue][color=green]

As I said - security problem.
[color=blue]
>*I* only pinged once. erwm.com[/color]
You write 'erwm.com' here, but your original post showed erwm.org.
Two different domains. One is in New York (.com) and the other in
Texas (.org).
[color=blue][color=green]
>> -c option to cut down the number of pings), and that host isn't

Minor sore point with me. If it doesn't answer three pings (-c 3), it
probably isn't going to answer in a hundred. Three is _usually_ enough
to establish that the connection works - anything more might be
considered abuse.
[color=blue][color=green]
>> 2) ask who ever is running the DNS server for 'blinkynet.net' WTF.[/color][/color]
[color=blue]
>By now, my head is just bleeding.[/color]
Are you the owner of the DNS zonefiles, or is downtownhost.com the
responsible party? A "wildcard" entry in the zonefile itself would
be a star, or "*.blinkynet.net" pointing at a single address. I don't
see it mentioned in the DNS-HOWTO, but it's mentioned in the "Cricket
Book" ("DNS and BIND" from O'Reilly).
[color=blue]
>I think I'll just hope it doesn't happen again. :)[/color]
Quick check - does a DNS query for "totally.unknown.host.blinkynet.net"
or "totally.bogus.hostname.blinkynet.net" return anything other that
"sorry, no cigar"? If it replies with an IP address, you have a
wildcard problem - if it doesn't, you're fine.

If you don't specify a DNS server, these query tools (dig, dnsquery,
host, nslookup) use one of the name server listed in /etc/resolv.conf.
However to find the "authoritative" name servers, there are several
ways. First is to use a whois query to get the information from the
appropriate registrar. In the case of "erwm.com', the initial whois
query of Notwork Solutions points me to whois.names4ever.com, and
asking them yields (among other things):
Domain servers in listed order:
ns1.abac.com 216.55.128.4
ns2.abac.com
(looks like names4ever.com doesn't know the IP of the second server).
A problem here is that Notwork Solutions only knows about a few top
level domains. Finding others can be fun, as there is no standard to
the name schemes - whois.dns.be, whois.cat, whois.nic.ch, whois.nic.cz,
whois.denic.de, whois.dk-hostmaster.dk, whois.nic.fr... at least MOST
of them begin with "whois.something" but this is not true for everyone.
Another solution, which USUALLY works is to query using your nameserver
to find all (or at least the NS records) for the domain.
[compton ~]$ host -t NS erwm.com
erwm.com name server ns1.abac.com
erwm.com name server ns2.abac.com
[compton ~]$
I'm using 'host' but all of these tools have the identical function
(man page says 'dig' wants 'dig erwm.com ns' - sounds good to me).

>ns1.abac.com. 1666 IN A 216.55.128.4[/color]
and there is the answer as well.
