I have a little business card website up for my big brother's media
consulting side-business at http://playomatic.myownsite.me.
Now, at the moment, if I try to load it in Google-Chrome-Stable, I'm
getting redirected to a yahoo! search for "create web",
If I try to load it in the floss chromium, I get a spammy landing page,
But in all of Iceweasel, lynx, w3m, elinks it loads fine, and nothing
has changed on my server (no redirect added to my vhost by an intruder
or any such thing), also neither ping nor traceroute seem to indicate
anything untoward or fishy.
The only thing I haven't tried is Epiphany, Konqueror, Safari, or IE.
Oddly, it seems to work fine in chrome on my android phone, though.
How can I determine what's interfering with this page loading in some
browsers, and not others? or what's redirecting my traffic, and how I
can stop it or prevent future re-occurrence?

Hi, it works well in my Chrome Browser.
May be you have some proxy between, or a misconfigured /etc/hosts entry.
Did you try to load it with all plugins disabled ?

I use no proxy/ies, neither at home, nor on the remote server.
My brother, who brought the matter to my attention was also using chrome
. disabling my extensions doesn't seem to make any difference.
There appears no mention of the url in any of my hosts files (neither at
home, nor on the server), nor anything that would redirect the IP
address, since I can load other sites on the same server (and the
myownsite.me domain) without troubles.
What else can I do?

One less-than-obvious conceivable factor that occurs to me is that
some webmail interfaces (looking at you, gmx.com) will point urls in
email text at creepy redirects (presumably so that your email provider
can log what you read).
For example, a link labeled
http://playomatic.myownsite.me
will point to
https://deref-gmx.com/mail/client/[Some-Alpha-Numeric-Code]/dereferrer/?redirectUrl=http%3A%2F%2Fplayomatic.myownsite.me
If one of those redirects happens to be broken, through no fault of
yours, then following such links in emails might result in unexpected
behaviour not unlike what you are seeing.
A shot in the dark, for what its worth.

the site in each browser, make sure you are really requesting
http://playomatic.myownsite.me, not the redirect some email provider
may have replaced it with.

Can you use the chrome developper tools to see what's going on ? (Press the F12 key while chrome is open) Select the network tab, and type the url in your address bar.
The network panel should show you what happens

trqacerout doesn't get redirect to a Yahoo! search like chrome does,
but nothing I see there seems ot clarify WHY or HOW it's getting
redirected, it's just showing me that it IS being led though some
circolocuitous route to where it should not.

A shot in the dark, but worth a try anyway: IPV4 vs IPV6?
But I'd rather suspect Chrome doing something weird to the URL before
resolving (or -- who knows! having its own built-in resolver).
Perhaps looking at the traffic with tcpdump/wireshark can give you
an idea.

Just wondering if it sees a url that doesn't start with www, and ends
with a slightly unusual '.me', and tries to 'autocorrect'. But .me is a
country code TLD, not one of the new ones as I first thought, so it
shouldn't be that.

It appears that Montenegro only came into existence (most recently) in
2006 - it was part of Yugoslavia, then 'Serbia and Montenegro'. So all
the 'good' codes were presumably taken.

Are you logged in with a google account on that chrome/chromium ? By the way, how did you install them ?
To resume :
On your debian computer, only for this website, you get redirect to ads only with chrome/chromium ?
I would try these :
purge chromium and chrome.
Install chromium and go to your website. (do not log in before).
The only things i can think of is broken extension. I've never see this happening, it's really strange. If that happens on windows i would have say, search for malware and delete them.

I WAS logged into my google account when I had the problem, in
fact, but eventually determined that when I logged out, I could load
the proper page for the url, oddly.
I installed chromium with aptitude, google-chrome-stable by downloading google's .deb pkg and doing sudo dpkg -i $said-google-pkg.deb

That is correct, Iceweasel, w3m, lynx and e-links all load the
proper page/site.
Chrome and dolphin on my android phone do fine, as well, but apparently chrome on iOS (what my brother was using when he found the problem), does not.

I'm not the OP, and I'm sort of piggybacking and going somewhat (or a lot?)

When I do ifconfig, I see that eth0 has both a 32 bit (e.g., 192.168.1.19) and
an inet6 address assigned.
Can anybody point me to a fairly short document that explains things like
which gets used under what circumstances, does one have precedence over the

As the address family for IPv4 is "inet" (vs "inet6"), you could say
"inet", but then it may not be so obvious that you were intending to
make a distinction between IPv4 and IPv6. So, perhaps "inet4" is not
so bad, or IPv4. Some go as far as to say "legacy". :)

On Linux, it would be best to get used to using the "ip" command
rather than "ifconfig". Issuing an "ip address" command will get you
all the configured addresses of the various families.

If we restrict the domain of this question to source address
selection then reading around from this point may help:
http://linux-ip.net/html/routing-saddr-selection.html
> does one have precedence over the other,
Clearly if there is just one inet address and one inet6 address,
then which will be chosen depends on which family the destination
address comes from. i.e., if the destination is an inet6 address
then the source address will have to be an inet6 address as well,
otherwise no communication will be possibleน.
If the destination address has been directly specified then that's
simple enough to predict.
Usually though, we are just dealing with host names that we wish to
communicate with. A host name is going to be presented to the
system's hostname resolution system, which may return a result from
/etc/hosts or some other database. More usually though it's going to
go out to DNS.
The DNS may contain both A (IPv4) and AAAA (IPv6) addresses with no
regard as to whether the client actually has a source address of the
matching family. That is, if you had a host with only inet6
addresses and you did a DNS query, you would still receive A records
as answers. If amongst the answers there were no AAAA records then
you'd have no way to communicate with the destination when the
application tried to do that.
It's the getaddrinfo() function of GNU libc that decides which
destination address to select for use. You can find more details
about that with "man getaddrinfo".
By default, if there are both inet and inet6 family addresses to
choose from, getaddrinfo will choose the inet6 one. So, if your host
has at least one configured global inet6 address then your
applications will tend to try to connect to inet6 destination
addresses, where available.
You can configure getaddrinfo's address selection in /etc/gai.conf.
A very common desire is to prefer inet addresses over inet6 ones,
and so on Debian the configuration required to do that is shown in
/etc/gai.conf commented out.
An application can be told to use a specific source address, but it
is more common for applications to be allowed to use any address. In
that case for inet it will generally be a reasonably simple case of
using the routing table to determine which source address is
"closest" to the destination.
For example, suppose you have an interface that has the addresses
192.168.1.1/24 and 192.168.1.175/25 on it. When attempting to
communicate with 192.168.1.180 the routing table will show that this
is in the same network as 192.168.1.175/25 and that that is the most
specific address.
When it comes to inet6 it can get a bit more complicated, especially
as it is much more common to have several inet6 addresses, and
you've got whole new concepts like privacy addresses and deprecated
addresses. But, it's all covered by RFC 6724, and this may help as a
summary:

> do they both use DNS,
As hopefully made clear by the above, it is not the addresses on
your system which "use DNS". It's more like your system uses DNS,
and the DNS may contain both inet and inet6 addresses, thus your
system decides which to communicate with based on which families of
address you have.
> and similar things which might let me make sense of the situation?
Hopefully that helped. It's quite a large topic, so some reading
will be required in many places to fully understand it.
Cheers,
Andy

to allow IPv4 networks and IPv6 networks to inter-operate. These

things like "NAT64" and "DNS64" for more information about these.

Hi Andy,
Thanks very much! It looks like quite a comprehensive answer (including
links) that I'll surely have to read more than once to absorb. (At that
point, I'll ask more questions if I feel the need.)
regards,
Randy Kramer

Other good stuff elided.

Except that it is Mongolia. Country TLDs have to be unique.

It works fine here. Chrome 54 on Jessie. Both fully updated.
