Following the instructions here:

https://ask.fedoraproject.org/question/10041/how-to-repair-unbootable-fedora-install/

I did this:

mv /boot/initramfs-2.6.32-358.0.1.el6.i386.img 
/boot/initramfs-2.6.32-358.0.1.el6.i386-nouveau.img
dracut /boot/initramfs-2.6.32-358.0.1.el6.i386.img 2.6.32-358.0.1.el6.i386

Interestingly enough, the new initramfs that I got from this command is slightly
smaller than the one that I already had in /boot.

Sadly, this made no difference.   When I booted the machine, I still got the
same dracut warning and kernel panic.

 I've finally figured out how to get an error message, but I have no idea of
how to fix it.

By removing "rhgb" and "quiet" from the grub commandline, I see a whole bunch
of write-up going by, then there is a several-second pause, and then this:

dracut warning: no root device "block:/dev/mapper/vg_ws194-lv_root" found

After that I get the kernel panic message and that's the end of the line.

By booting the machine from the rescue cd, I can
find /mnt/sysimage/dev/mapper/vg_ws194-lv_root, which is a symbolic link
to ../dm-0

/mnt/sysimage/dev/dm-0 exists.

lvscan tells me this:
ACTIVE '/dev/vg_ws194/lv_root' [50.00 GiB] inherit

lvdisplay shows a bunch of stats about  /dev/vg_ws194/lv_root that look normal
to me.

In summary, it looks very much like vg_ws194-lv_root is indeed present and
accounted for, but dracut didn't find it for some reason.

I am sure someone has something more current, I think my old box was 
running C5.3 or even earlier. I saved the control files off it and my 
ifcfg-ppp0 was:

USERCTL=no
BOOTPROTO=dialup

PEERDNS=no
DEMAND=no
PERSIST=no
IPV6INIT=yes
PPPD_EXTRA="ipv6 ,"

There was also a ppp directory that had files: options, pap-secrets, and 
chap-secrets

But like I said, old box.

I don't have a backup copy of the grub.conf file since it's always been
automatically managed and updated by grub and friends and I've never really had
to pay much attention to it.

I did compare it between the non-working and the working machines and didn't
see anything that struck me as a significant difference.

The most maddening part of this is that all of the files and the filesystems
appear to be present -- I can boot off of a rescue CD and mount the whole works
under /mnt/sysimage and browse to my hearts content.  I just can't boot the
damn thing.

How is a name like /dev/mapper/vg_ws195-lv_root rd_NO_LUKS determined?  If I
knew how to read or find out what the actual name of the root directory was on
the problem machines, I could compare it to what's in the grub.conf file.

Here are two very good links:

http://campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMailServer
http://wiki.centos.org/HowTos/Amavisd

I have used both as guideposts, and found problems with both, as people 
here and on related lists will attest to be the questions resulting by 
following other's instructions lead to strangeness.  I really suggest 
that you step slowly into this.  There is a lot to do to get all the 
pieces together.  A lot you need to understand with each package.  And 
then things not even covered, but you are expected to know when setting 
up a server.  Like php.conf, you need to set your timezone.  None of the 
tutorials for things like roundcube tell you this; you are expected to 
know about using php.

You should never disable the server firewall. It is easy to figure out 
what ports are necessary and open only those.  As far as selunix, this 
is hard.  I have been given a set of scripts to work out what to enable 
for selinux, and this is still a work in progress for me.

So what?  Read the press about "Advance Persistant Threats".  Only open 
what is necessary.

Figure out the ports you need.  This is not hard.  It is easy compared 
to the rest you will have to learn.

I have the wounds, even with my kevlar suit.  :)

BTW, I am putting together my own blog on what I am doing.  I have to 
work out a few pieces to get my mysql passwords out of the scripts I 
use, but I have learned a lot over the past few months, and really 
should share.  some.

I can indeed see all of the files on that computer, including the boot
directory and everything under /

I don't know what to do from that point, though.

Here is the grub.conf from the working system, which is pretty much identical

how do I find out what to change it to?

Boot to rescue mode and see if you can mount the device containing the root 
filesystem readonly and see all the files on it.

Then check that the kernel root option is looking at the same device.

No, it is not required.  But you do need to accept TCP traffic on port
25 to your SMTP host.  Because you need to do this, you should make sure
your SMTP server can not be used as an open relay, or you will find
yourself on many blacklists.  Here's a reasonable tester I found:

Interesting.  How can I check that?  I have another almost-identical system

Just panicsville.   I am trying to pack up to fly to meetings tomorrow, 
and saw this big update.  It has been too long since I was serious with 
Centos, and forgot that dot releases are major changes to the life of 
your server.  No way to bite off small bits.

So I will download the full current repos to my server over the week 
way, then apply them after I get back.

Just a case of bad timing on my part, resulting in an unnecessary panic.

It says,
Prerequisites:

   - The mail server should contain a valid MX record in the DNS server.
   Navigate to this link how to setup DNS
server
   .
   - Firewall and SELinux should be disabled.


I have disabled iptables as my m/c is behind the firewall.

That's exactly what it's doing.  The "/6" base and update repository
always point to the latest version.  6.4 was released this week so
the "/6" is now seeing lots of updates as a result.

This is not new.

I am being hit on a number of my systems with yum update reporting 270+ 
rpms to update, and MOST are coming from the base repo.  I checked a few 
out, and yes, they are of a higher release.

I don't recall ever seeing the base repo change; it is almost like it is

Anyone else seeing this.  I JUST did an install from my local repo copy 
of the 6.3 base and update using a netinstall kickstart, then yum tells 
me that there are 270+ updates...

Re: [CentOS] Apache setup problems

I didn't think I needed to make the files executable.  Anyway, the simple
index.php has a title, an H1 tag and a couple php statements, one of which
is phpinfo();
My page, that I get has just the title and the content inside the h1 tag.
When I view the source, there is nothing that was inside a php block.
Meaning, it didn't run the php code and output html.  
I was looking at the apache error log and not finding anything useful.

So you aren't getting 404 anymore?
What do you mean by "thrown out"?
Do you see a blank page?
How do you know there's no attempt? (As opposed to an attempt that fails for
some reason yet to be determined.) What does your Apache error log say?

I just had a thought:  Is it possible to just reformat and reinstall the /boot

You shouldn't. PHP pages work just fine without execute permission.

So you aren't getting 404 anymore?
What do you mean by "thrown out"?
Do you see a blank page?
How do you know there's no attempt? (As opposed to an attempt that fails
for some reason yet to be determined.)
What does your Apache error log say?

I booted the "Centos 6.4 minimal iso", told it to "upgrade an existing
installation", and to install the bootloader.  About all that it appeared to do
was install the bootloader.  Unfortunately, the machine still didn't boot.

The bootloader seems to be fine -- grub itself boots up.  I get a kernel panic
after that, when you normally see the messages about unpacking vmlinuz and so
on.  I just get a blank black screen with a flashing cursor (or the rhgb
screen with the spinning doodad, depending on the grub setting) and then a
kernel panic.

Yes it does. The name can now be resolved.

That's a separate problem, and has nothing to do with BIND.
What's more, given the complete lack of information about the network
topology and involved components, we cannot even guess what may be the
issue here. Routing? Firewall? NAT? Hardware? Everything's possible.

It seems you already fixed that and just forgot to tell the list.

This zone file does not contain an A RR for netcloudjobs.com itself, but
if I dig netcloudjobs.com now I do get one. So obviously you have added
it it the meantime.

Generally speaking:
1. fix the name resolution (you already did that)
2. fix the network connectivity and/or firewall issues preventing your
ping packets from getting through

After reading the entire thread I am still not sure what your actual
issue is. I can only guess some name resolution is not working as expected.

Please state:
- From which machine are you trying to resolve?
- Which name are you trying to resolve?
- Which result are you expecting?
- Which result do you get?

In the meantime, a few comments on your config.

> options {
> listen-on port 53 { 127.0.0.1; 10.0.0.1; };

That doesn't look right. You said your machine has a public IP address
but you make it listen on a private IP address and localhost only.

> listen-on-v6 port 53 { ::1; };

That doesn't look right either. If your machine does IPv6, why have it
listen only on localhost? If it doesn't, why have it listen on IPv6 at all?

> allow-query { localhost; 10.0.0.1/24; 10.0.0.254/24; };

This doesn't look right at all. Neither 10.0.0.1 nor 10.0.0.254 are
compatible with a /24 netmask.

> dnssec-enable yes;
> dnssec-validation yes;
> dnssec-lookaside auto;

I don't think it's a good idea to activate DNSSEC before you have the
basics running.

It's very strange to declare two nameservers with the same address. Why
put in ns2 in the first place if it's actually the same machine as ns1?
That doesn't make sense.

> And my reverse zone file looks as

> ns2 IN  A   173.201.189.43

These entries are wrong here.
Simple explanation: A RRs belong in the forward zone, not the reverse zone.
Complex explanation: The RRs you actually create by this look like this:

ns1.189.201.173.in-addr.arpa. IN A 173.201.189.43
ns2.189.201.173.in-addr.arpa. IN A 173.201.189.43

> 43  IN  PTR ns1.netcloudjobs.com.
> 44  IN  PTR ns2.netcloudjobs.com.

You have a forward/reverse mismatch here. Your reverse zone resolves
173.201.189.44 to ns2.netcloudjobs.com but your forward zone resolves
that to 173.201.189.43 instead of 173.201.189.44.

I am:

[ts@dns01 ~]$ host ns1.netcloudjobs.com
ns1.netcloudjobs.com has address 173.201.189.43
[ts@dns01 ~]$

Looks fine to me. So again, please state from where you are trying the
resolution, which result you expect and which result you get.

It's looking more and more like a full nuke-and-pave is going to be the answer
here.

As I suspected, initramfs-2.6.32-358.0.1 was missing in /boot.  Unfortunately,
none of the other installed kernels boot either -- everything gives me a kernel
panic.

I  did a yum remove kernel-2.6.32-358.0.1 and yum install kernel-2.6.32-358.0.1
and the whole transaction appeared to be successful.

That got me  initramfs-2.6.32-358.0.1 back in /boot, but I still get a kernel
panic when I reboot the machine.  The initial rhgb screen comes up and the
little circle thing cranks for a minute or so, but then I get "kernel panic:
attempted to kill init!". Booting without rhgb gives me a cursor in the top
left corner for a minute, followed by "kernel panic: attemtped to kill init!".
The last time /var/log/boot.log was written to was the last time the machine was
rebooted prior to this whole episode (i.e. a few weeks ago) so there is
absolutely no error message or log information available other than the kernel
panic message on the screen.

Damn, I hate the idea of having to set all of these machines up again from
scratch.  Two of them aren't much to re-do, but the third one is the office
workhorse machine that does everything from dhcp server to nfs server to print
server to you-name-it.

well, so far when trying to build perl-sdl it says it can't find "-lSDL",
and this being Perl, I can't figure out what the heck is wrong,... libSDL
certainly exists, and yes I've installed sdl-devel.

but it looks as if Akemi may have the answer to my prayers so I can

I have posted it months ago here:

Actually, I also posted to the c6 fora back then and suggested to 
document it more precisely in the wiki.

That posting was immediately closed without further ado. Someone even 
followed me to the skype fora, only to state that I'm just talking 
bullshit and that http://wiki.centos.org/HowTos/Skype has all you need 
to know.

And of course yes: Skype-4.1 is running nicely here on x86_64 for all 
these months. And it doesn't require anything special -- and certainly 
not breaking your installation with some weird Qt-4.7.

Interestingly, Fedora 17 is only at 0.7.3-10.  It would be nice for a 
more current version, but for what I need, if it works with WPA-PSK it 
will be good enough for now for the lab I am building for my son.

I can see why such an app is not even in EPEL, as who would run an AP on 
a enterprise server?  Someone that wants enterprise code in a portable 
lab environment and not have to also lug along an AP. Even the Tenda 
AP.  (Centos for this lab is loaded on an old OQO2).

some.hostapd itself, http://hostap.epitest.fi/hostapd/  is up to 2.0

Thanks Harald!  Though I need the i686 version, but given the x86_64, I 
found the i686 one.

I just found hostapd for Fedora, but it is not showing up in my Centos

[CentOS] 802.11 Access Point software

[Robert Moskowitz]

Is there a way (software) to turn a Centos server into an AP?

The server will have DHCP and RADVD, so no ARP proxying needed. This is 
for a small lab setup.

yumex is not helping me search for an answer.

The reason I said yum update was still running was because I've had this exact 
scenario occur before.

VNC died during yum update and when I got back in I could see that yum update 
was still running.

I just waited until it finished.

I hope it is only your initramfs.  If that isn't it, for me I would just 
restore and rerun the update.  Much less time
involved.

If yum was indeed still running, it wasn't using any significant CPU.  I did
run top in my login terminal to see if anything significant was going on and yum
didn't show up on the list.

When I attempted to re-connect to vncserver after that, I was told "connection
refused", and "service vncserver start" cranked up another session for me
without any errors.

I think vncserver just altogether crashed for some reason, probably related to
the yum update that I was running on that machine at the time.  I suppose the
lesson learned here is to always update the host machine from a screen session
running in a plain terminal, not through a vnc session.

> It may be easier to restore from backup and then attempt to do the update

Perhaps, but since everything seems to still be in place on those hard drives,
and since my last "yum update" completed without any errors being reported, I
suspect (hope?) that everything is still ok with the exception of whatever is
causing the machines to fail to boot.

[CentOS] Older versions of packages disappearing from yum repos

[Brian Lalor]

I've been designing the infrastructure for a new team using CentOS 6 and 
Puppet.  I'm still learning Puppet, but thought I had things pretty well under 
control.  After this week, I'm beginning to wonder… :-)

In the last week I've had versions of three packages disappear from the yum 
repositories I'm using, both EPEL and the standard ones from a base CentOS 6.3 
install.  Since I'm trying to install specific versions of packages with 
Puppet, this is a problem.  The most recent one that just turned up this 
morning is kernel-devel.  I have the following resource defined in one of my 
Puppet manifests:

   package {"kernel-devel-${::kernelrelease}":
   alias => 'kernel-devel',
   }

I'm trying to ensure that I've got the kernel-devel package installed that 
matches the kernel I'm currently using. I naively assumed that once a package 
was made available via the official CentOS mirrors that it would never 
disappear.  That doesn't appear to be the case.  I have  
kernel-2.6.32-279.19.1.el6.x86_64 installed. 
kernel-devel-2.6.32-279.19.1.el6.x86_64 is gone, apparently replaced with 
kernel-devel-2.6.32-358.0.1.el6.x86_64. I have a couple of other packages that 
have given me problems, too, namely ngircd which was upgraded from 18 to 20.1.

How do I manage this problem?  Do I need to maintain my own mirrors?  That 
seems like a horrible solution.  Is there another CentOS repository I should be 
using?  Am I just going about this all wrong?

Thanks,
Brian

What most likely happened:

The "yum update" that was running in your lost VNC session was in all 
likelihood still running.

If you had done a 'ps -ef | grep yum' you would probably have seen that yum 
update was still running.

And then it looks like you logged back in to a new session and began running 
other yum commands before the original "yum
update" had completed.

So now you have a mess that may not be easy to untangle.

It may be easier to restore from backup and then attempt to do the update again.

I was doing it through VNC, thinking that would be more-or-less equivalent to
screen, which it apparently isn't.  Somehow my vnc session (desktop) just
disappeared in the middle of the job, while I was running "yum update" on the
remote host machine and two other computers.  Perhaps the "yum update" that was
running on the remote host machine killed VNC -- in hindsight perhaps I
shouldn't have done that.

My google searching leads me to suspect that initramfs may be missing on those
computers. If that is the case (which I will verify later this afternoon) then
I'm thinking that perhaps chrooting to the hard drive followed by a simple yum
remove kernel-2.6.32-358.0.1 and yum install kernel-2.6.32-358.0.1 will fix it. 

It's funny that all three of them died in the same way, though I guess they
were all at about the same stage in the update process when my VNC session
disappeared.

Running "yum-complete-transaction", followed by "package-cleanup --cleandupes",
followed by "yum update" seems to have put everything back the way that it
should be, with the exception of whatever it is that prevents the machine from
booting.

And along with this, you have DNSSEC enabled, so your firewall and

I figured that, but I now have an /etc/redhat-release saying 6.4, as does

My CR was probably not fully updated--I probably check for updates about
once every two weeks, but there was a relatively large one a little while
ago.  

Thanks for the clarification.

Re: [CentOS] BIND Setup Issue

[Peter Eckel]

Hi Austin, 

since your A record is fine and can be resolved, the issue is obviously not 
BIND related but lies somewhere in your network/firewall configuration.

The last address that is visible in the tracereoute output from here is 

> 15  ip-208-109-113-174.ip.secureserver.net (208.109.113.174)  163.811 ms  
> 163.984 ms  164.166 ms

so the issue must be somewhere between 208.109.113.174 and 173.201.189.43. 
Another IP (probably another customer of GoDaddy) in your /24 range is directly 
connected to 208.109.113.174 which makes it likely to be your next hop as well:

> 15  ip-208-109-113-174.ip.secureserver.net (208.109.113.174)  178.314 ms  
> 165.344 ms  165.293 ms
> 16  ip-173-201-189-1.ip.secureserver.net (173.201.189.1)  164.007 ms  163.767 
> ms  163.820 ms


So probably the issue is in your router setup (packet filters and/or NAT, if 
applicable) or in the configuration of your own machine (iptables?).

  Peter.

We don't release redhat-release in CentOS at all ... we have
centos-release instead.

We also don't release centos-release into CR, only in the new version's
main tree.  Anaconda (the package that installs CentOS) and
centos-release are the only packages from the new version that normally
are not installed in the CR.  Getting a new centos-release is how you
know you are updated to 6.4 and not running 6.3/CR.

In this case, there were a couple of other packages in 6.4 on release
day that were not released into 6.3/CR, but this is because the packages
are updates to 6.4 and were released the same day we released 6.4.  They
are:

ipa-3.0.0-26.el6_4.2.src.rpm
qemu-kvm-0.12.1.2-2.355.el6_4.2.src.rpm
ruby-1.8.7.352-10.el6_4.src.rpm
tzdata-2012j-2.el6.src.rpm
xulrunner-17.0.3-2.el6.centos.src.rpm

The reason these did not go into 6.3/CR is that CentOS 6.4 was released
before we built them. Since CentOS-6.4 is released, there will be no
more updates posted in 6.3 CR.

This would mean that if you were on a fully updated 6.3/CR and upgraded
to 6.4, you would expect to see all the RPMS associated with the above 5
SRPMS, as well as centos-release and anaconda.

Thanks,
Johnny Hughes

Who is your registrar for netcloudjobs.com and have they listed your two 
servers and their IP addresses?

Yes, I think that should work. I was worried that "received disconnect"
messages might also appear for legitimate connections, but looking
through my logs it seems that they don't.

I have set it up as a test on one of my servers with a threshold of 15
attempts in 1000 secs now to see how it will fare.

Thanks,

Re: [CentOS] BIND Setup Issue

[Austin Einter]

Dear All
My resolv.conf looks as below

search netcloudjobs.com
nameserver 10.0.0.1
nameserver 8.8.8.8
nameserver 127.0.0.1

I do not have any error logs.

I just did one modification in named.conf.

*allow-query { localhost; 10.0.0.1/24; 10.0.0.254/24; };

*
*Line I modified to

*
*allow-query { any; };*


With this change, now I am able to ping to ns1.netcloudjobs.com . Problem
is 50% resolved.

Kindly guide me if allow-query any is right thing to do or not.

Next, how do I make sure www.netcloudjobs.com should resolve to my IP.

In my BIND server the, the command "dig www.netcloudjobs.com" gives below
output.

[root@ip-173-201-189-43 named]#
[root@ip-173-201-189-43 named]#

Can I assume that my configuration is proper? As just now I am able to ping
ns1.netcloudjobs.com from remote machines, so pinging to
www.netcloudjobs.com will take some more time.

Please guide me...

Austin

First off ... from now on run yum updates inside a "screen" session. 
Install with:

yum install screen

Here is info on sreen:

http://library.linode.com/linux-tools/utilities/screen

At this point you will need to clean up before you install screen.  You
might first try the utility yum-complete-transaction:

http://www.vmadmin.co.uk/linux/44-redhat/209-linuxyumcomptrans

As soon as you get the transaction completed, install screen and ALWAYS
do yum updates in a screen or vnc session so that the transaction will
complete if you drop the connection.

Re: [CentOS] lost connection during yum update

[Scot P. Floess]

For whatever it's worth - I yum update'd two VMs without any trouble 
whatsoever (from 6.3 to 6.4) and am in the process of updating a laptop...
Not that it should matter but they are both guests running on a CentOS 5.9 
Xen host.

I'm in the process of updating a laptop - I'm hoping it works too...

[CentOS] BIND Setup Issue

[Austin Einter]

Dear All
I have a CentOS 6.3 machine. I am trying to setup DNS BIND setup in that
machine. It is having a static global IP. I have done lot of reading ,
google search and tried all possible option, but still not able to resolve
the issue.

My named.conf looks as below.

*
*
*
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

options {
listen-on port 53 { 127.0.0.1; 10.0.0.1; };
listen-on-v6 port 53 { ::1; };

query-source address * port 53;
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { localhost; 10.0.0.1/24; 10.0.0.254/24; };
recursion yes;
dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;

/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";

managed-keys-directory "/var/named/dynamic";
};

logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};

zone "." IN {
type hint;
file "named.ca";
};zone "netcloudjobs.com" {
type master;
file "netcloudjobs.com.fwd";
allow-update { none; };
};

zone "189.201.173.in-addr.arpa"  {
type master;
file "netcloudjobs.com.rev";
allow-update { none; };
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
*
Next my forward zone file looks as below
*
$TTL 86400
@   IN  SOA ns1.netcloudjobs.com. root.netcloudjobs.com. (
2021071001  ;Serial
3600;Refresh

604800  ;Expire
86400   ;Minimum TTL
)

@   IN  NS  ns1.netcloudjobs.com.
@   IN  NS  ns2.netcloudjobs.com.

ns1 IN  A   173.201.189.43
ns2 IN  A   173.201.189.43
*
And my reverse zone file looks as


*$TTL 86400
@  IN SOA ns1.netcloudjobs.com. root.netcloudjobs.com. (
2021071001  ;Serial
3600;Refresh

)

@   IN  NS  ns1.netcloudjobs.com.
@   IN  NS  ns2.netcloudjobs.com.
ns1 IN  A   173.201.189.43
ns2 IN  A   173.201.189.43
43  IN  PTR ns1.netcloudjobs.com.
44  IN  PTR ns2.netcloudjobs.com.
*
I hope I am doing something wrong with configuration. I have done this
since more than 60 hours. Still I am not able to resolve
ns1.netcloudjobs.com.

Can somebody help here.

Unfortunately older Radeon HD 4000, HD 3000, HD 2000 Series are NOT 
currently supported as the current AMD driver does NOT support the new 
version of Xorg in 6.4.

So your HD 4800 series is NOT supported.

Radeon HD 7000, HD 6000, HD 5000 Series ARE supported by the version 
13.1 driver currently in the testing repo. I've had a couple of reports 
that this driver works so I'll move it to the main repo shortly. If you 
have supporting hardware I would recommend updating to this driver 
before performing the 6.4 update.

Try service NetworkManager restart, and see how that goes. Or try 
"disconnect" for wireless and connect again.
Also, do you have wpa security? Maybe downgrade wpasupplicant (or what 
ever actual package is in charge)?

An user pointed out that some mirrors have 6.4 files few days ago, so I 
checked. I started from US mirror list from the top,  and in first 10-15 
mirrors about 1/3 had 6.4 folder, with 3 distinct dates, March 6th, 
March 7th (same time, timezone diff maybe) and I think some where even 
March 8th.

I though I posted query about it in CentOS-devel list, but it managed to 
sent it from my main mail account, that I do not use for mailing lists 
any more, so it got rejected.

Re: [CentOS] Apache setup problems

[Bruce Whealton]

I am using http://www.dnsdynamic.org/ for the subdomain
fwwebdev.dnsdynamic.com and I changed from http://freedns.afraid.org/ to 
dnsexit.com for the domain futurewavewebdevelopment.com since the servers at
afraid.org seemed to have stopped forwarding the domain.  
So, it works, except for the php part.  I made the files executable.  
What I mean by the php part doesn't work is that it is just being thrown
out.  There is no attempt to process it as php.  I think I mentioned
elsewhere that
the php was installed using yum.
Thanks,
Bruce

I'm curious on your dynamic dns setup:
  - are you using ddclient? or something else?
  - which registrar server are you using, zoneedit or someone else?
  - any other details that you can provide on the setup

Thanks.
