#88861 — Any GNU/Linux Gurus. Need Help

GNU/Linux serves my needs except for paying some bills.

It seems that some commercial sites, for whatever reason, do not
interact too kindly with GNU/Linux versions of the standard browsers.

For example, try this link with a recent install of the Firefox
browser:

<https://auth.proofing.statefarm.com/login-ui/login?>

Don't worry.  You don't need a StateFarm account.  But the link
should produce a "Server Not Found" error which is inexplicable.

As I indicated, this occurs with GNU/Linux Firefox and also with
GNU/Linux Iron browser (based on Google Chrome).

<https://www.srware.net/iron/>

So why is this happening?  What is so different about the GNU/Linux
environment that causes this to fail?

I am forced to use Firefox on Micro$lop Winblows (yecch!) to access
this site and pay my insurance bills.

I encourage any readers of this post to try to access the above link
with a GNU/Linux browser and report the result.

Same here, and it goes through the motions of looking for a passkey that 
I don't possess.

It seems that the browser is not at fault.  I can use the "host"
command and the result is that it can't look up the site:

[~]# host auth.proofing.statefarm.com
Host auth.proofing.statefarm.com not found: 3(NXDOMAIN)

I am using a caching nameserver based on pdnsd and the problem
must be somewhere in the configuration for that.

When I do this here I get the following:

host auth.proofing.statefarm.com
auth.proofing.statefarm.com is an alias for auth.proofing.ciam.c1.statefarm.
auth.proofing.ciam.c1.statefarm has address 143.204.181.75

Thanks for that.

The problem is in the DNS lookup.  The DNS server cannot lookup
the address.  This would thus occur with any browser.

As far as I can tell, on my system this is the only site that
has this problem.

I have to do some some network debugging, but since my insurance
bills are paid for the next year the matter is not urgent.

Firefox can do DNS lookup on its own, ignoring the system.

The same message occurs many times:

IP 192.168.0.2 > c.in-addr-servers.arpa: ICMP 192.168.0.2 udp port xxxxx unreachable

192.168.0.2 is the address of my machine on the LAN.

Unfortunately, I am not at all versed in network programming but the response
"192.168.0.2 > c.in-addr-servers.arpa" seems to indicate that my machine is telling
the nameserver that the (local?) UDP port is unreachable.

Any comments?

Yes. 192.168.0.2 is rejecting the replies to the DNS queries it issued.

It’s consistent with a misconfigured local firewall.

It's regular behavior of Linux xtables. I don't know whether this
behavior also happens with the later nftables backend, but it has
something to do with the UDP state machine that is implemented with
the ESTABLISHED, RELATED packet classifications.

I am far from being sure, but I most often see this on high-latency
links like cell data when the answer comes like 20 seconds after the
query (when the connection tracking entry might already timed out).
Another hypothesis is that the local resolver queries multiple
servers, takes the quickest answer and then rejects the remaining
answers. But I think that might be unreasonable, why would the
software actively reject the answer instead of silently dropping it on
the floor.

I never investigated that in depth.

The RTTs are 30-40ms here.

Using a separate socket for each outbound query and closing the
redundant ones would have that effect, I think. Seems rather inefficient
but consistent with what we see.


However, I think it is a side issue, swamping the real problem.
Stripping the packet capture down to the essentials:

What's supposed to happen next is following the CNAME reference to
auth.proofing.ciam.c1.statefarm, which works fine if I try it by hand,
and BIND manages fine as well. But there is no evidence in the packet
capture of the OP's system doing this.

I guess pdnsd has bugs relating to CNAMEs or to TLDs introduced after it
stopped being maintained, or both.

Why an insurance company needs a TLD is unclear but there don’t seem to
be any issues with it.

> P.S.: Oh, yes, and please, alwas run tcpdump with -np.

Agreed. All the PTR queries from tcpdump are also swamping the relevant
stuff.

Like many companies they recently redesigned the site for the hell of it. 
Previously you could enter the policy number and pay the bill without 
logging in. After the redesign you had to create an account based on your 
phone number. I've had State Farm since New Hampshire revoked GEICO's 
license in the '80s. If anyone ever asked me for a telephone number in the 
ensuing years I certainly don't remember it. 

I called my agent. She verified I never had a phone number on record, 
added it, and sent me a registration link. That wasn't my primary reason 
for calling. State Farm had sent out a flurry of snail mail saying they 
were revampng their billing system. Previously you got a renewal notice 
well in advance of the renewal date. Under the new system the notices are 
sent much later. I knew my policy was up for renewal and had not received 
the bill yet and was worried. 

Cyber security and all that but online sites certainly are a joy to use 
these days.

   Look, it's NOT "better" - just Totalitarian
   State shit.

   And if they're only TAKING money ... why the
   fuck do they need more ID or captchas (which
   I'm getting too old to see well) ???

   THINKING about hiring some lawyers to file
   a group ADA complaint about the 'captchas'.
   Do NOT expect anyone over 65 to be able to
   spot where EVERY bit of the "bicycle" or
   whatever is in the damned half-inch images.

And yet you bitch about the proof of work CAPTCHAs like Anubis.

Of the few sites I notice using Anubis, none of them has ever required 
me to 'interact' with it, I just get an interstitial page, and then it 
lets me in.

Precisely. C182282 was upset with Anubis and other newer CATCHAs even if 
he didn't have to identify all the squares with cats or try to decipher 
distorted text.

Strange. I get the same message from the Netherlands via Tor. 

"Music video by Steve Earle & The Dukes performing I Ain't Ever Satisfied.

The non-video link is also provided by UMG. Copyrights and digital media

Perhaps you shouldn't have tried to set up DNS caching.
