DRb connection issues

    This is not a DRb problem, so much as a system configuration problem. I know
    this already, but I can't figure out why DRb will not connect. I have two
    machines, plugged into a switch, and both have static IPs. I have had DRb
    talking just fine before, but only for a while, so I'm not sure why it won't
    talk now, and I thought I had already solved the problem by placing the
    whatever.fylz.com before localhost.localdomain in the /etc/hosts files. I
    have not rebooted either machine (but it was overnight), so I do not know now
    why they DRb will not talk.

    The problem seems to be name resolution, so I'm playing around with /etc/hosts
    to see if I can get us to talk.

    I'm using the dchats.rb and dchatc.rb included with the DRb examples. I start
    the server on one machine (called costarica) and see this:

    kevin@costarica:~/drbsample$ ruby dchats.rb
    druby://costarica.fylz.com:1242
    [return] to exit.

    I start the client on the other machine (called nicaragua) and see this:

    kevin@nicaragua:~/ruby/drb$ ruby dchatc.rb druby://costarica.fylz.com:1242
    kevin
    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:733:in `open':
    druby://nicaragua.fylz.com:39879 - #<Errno::ECONNREFUSED: Connection refused
    - connect(2)> (DRb::DRbConnError)
    from
    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:726:in `each'

    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:1185:in
    `initialize'
    from
    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:1165:in `new'
    from
    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:1165:in `open'
    from
    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:1082:in
    `method_missing'
    from
    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:1081:in
    `with_friend'
    from
    (druby://costarica.fylz.com:1242) /usr/lib/ruby/1.8/drb/drb.rb:1081:in
    `method_missing'
    from (druby://costarica.fylz.com:1242) dchats.rb:14:in `initialize'

    from (druby://costarica.fylz.com:1242) dchats.rb:37:in `add_member'
    from dchatc.rb:37

    I can ping both machines by name from each other just fine:
    kevin@nicaragua:~/ruby/drb$ ping costarica
    PING costarica.fylz.com (192.168.2.105) 56(84) bytes of data.
    64 bytes from costarica.fylz.com (192.168.2.105): icmp_seq=1 ttl=64 time=0.226

    kevin@costarica:~/drbsample$ ping nicaragua
    PING nicaragua.fylz.com (192.168.2.102) 56(84) bytes of data.
    64 bytes from nicaragua.fylz.com (192.168.2.102): icmp_seq=1 ttl=64 time=0.206
    ms

    Both know their host name:
    kevin@nicaragua:~/ruby/drb$ hostname
    nicaragua.fylz.com

    kevin@costarica:~/drbsample$ hostname
    costarica.fylz.com

    And here are the contents of both of their /etc/hosts files:

    kevin@nicaragua:~/ruby/drb$ cat /etc/hosts
    127.0.0.1 nicaragua.fylz.com localhost.localdomain localhost
    nicaragua
    198.186.207.1 router

    192.168.2.105 costarica.fylz.com costarica
    192.168.2.102 nicaragua.fylz.com nicaragua

    kevin@costarica:~/drbsample$ cat /etc/hosts

    192.168.2.105 costarica.fylz.com costarica
    192.168.2.102 nicaragua.fylz.com nicaragua

    The server (costarica) is running Debian Sarge and the client is on Kubuntu
    Hoary. Does anyone have any idea why I see the above error? I certainly
    don't.

    It does.

    They're obviously not. So what do I change to get them to be?

    > Lines 4 and 5 should be identical


    They are.

    It's not the last item, but is there.

    And just to make sure that it's still happening, I tried running the dchats
    and dchatc programs again and got the same error.

    Makes sense.

    Maybe try:

    192.168.2.105 costarica.fylz.com costarica
    192.168.2.102 nicaragua.fylz.com nicaragua

    This is before the modifications that Eric so kindly gave that I will try
    next. :)

    root@nicaragua:/home/kevin # hostname --fqdn
    nicaragua.fylz.com

    costarica:/home/kevin# hostname --fqdn
    costarica.fylz.com

    Looks kosher, no?

    This is why I was whining so heavily a month or so ago. I can connect to the
    postgres server on this machine with no problems.... Is there any reason
    that DRb needs to use hostnames?

    Anyway, now with the /etc/hosts modifications, here's the same 5 commands on
    both:

    == Server ==
    kevin@costarica:~/drbsample$ ruby -rsocket -e 'p Socket.gethostname'
    "costarica.fylz.com"

    kevin@costarica:~/drbsample$ ruby -rsocket -e 'p
    Socket.gethostbyname("costarica.fylz.com")'
    ["costarica.fylz.com", ["costarica"], 2, "\300\250\002i"]

    kevin@costarica:~/drbsample$ ruby -rsocket -e 'p
    Socket.gethostbyaddr("\300\250\002i")'
    ["costarica.fylz.com", ["costarica"], 2, "\300\250\002i"]

    kevin@costarica:~/drbsample$ ruby -rsocket -e 'p
    Socket.gethostbyname("nicaragua.fylz.com")'
    ["nicaragua.fylz.com", ["nicaragua"], 2, "\300\250\002f"]

    kevin@costarica:~/drbsample$ ruby -rsocket -e 'p
    Socket.gethostbyaddr("\300\250\002f")'
    ["nicaragua.fylz.com", ["nicaragua"], 2, "\300\250\002f"]

    == Client ==
    kevin@nicaragua:~/ruby/drb$ ruby -rsocket -e 'p Socket.gethostname'
    "nicaragua"

    kevin@nicaragua:~/ruby/drb$ cat /etc/hosts
    127.0.0.1 localhost.localdomain localhost

    # The following lines are desirable for IPv6 capable hosts
    ::1 ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    ff02::3 ip6-allhosts

    192.168.2.105 costarica.fylz.com costarica
    192.168.2.102 nicaragua.fylz.com nicaragua

    kevin@nicaragua:~/ruby/drb$ hostname
    nicaragua
    kevin@nicaragua:~/ruby/drb$ sudo hostname nicaragua.fylz.com
    Password:
    kevin@nicaragua:~/ruby/drb$ hostname
    nicaragua.fylz.com
    kevin@nicaragua:~/ruby/drb$ ruby -rsocket -e 'p Socket.gethostname'
    "nicaragua.fylz.com"

    So.....what the heck here....?

    kevin@nicaragua:~/ruby/drb$ ruby -rsocket -e 'p
    Socket.gethostbyname("nicaragua.fylz.com")'
    ["nicaragua.fylz.com", ["nicaragua"], 2, "\300\250\002f"]

    kevin@nicaragua:~/ruby/drb$ ruby -rsocket -e 'p
    Socket.gethostbyaddr("\300\250\002f")'
    ["nicaragua.fylz.com", ["nicaragua"], 2, "\300\250\002f"]

    kevin@nicaragua:~/ruby/drb$ ruby -rsocket -e 'p
    Socket.gethostbyname("costarica.fylz.com")'
    ["costarica.fylz.com", ["costarica"], 2, "\300\250\002i"]

    kevin@nicaragua:~/ruby/drb$ ruby -rsocket -e 'p
    Socket.gethostbyaddr("\300\250\002i")'
    ["costarica.fylz.com", ["costarica"], 2, "\300\250\002i"]

    But still...
    kevin@costarica:~/drbsample$ ruby dchats.rb
    druby://costarica.fylz.com:1257
    [return] to exit.

    (By the way, while that's running)
    kevin@costarica:~$ netstat -l

    Proto Recv-Q Send-Q Local Address Foreign Address State
    tcp 0 0 *:8000 *:* LISTEN

    And I obviously talk:
    kevin@nicaragua:~$ telnet costarica.fylz.com 1257

    I'm at a loss.
