Re: Odd behavior on CNAME

Hi,

I probably should mention:
- other working sites are doing fine over the proxy
- domains without any record are throwing the mentioned error properly

It should return:

<!-- ERR_DNS_FAIL -->

… page.

And it takes 100 ms.

 

Can you re-test it?

Also make sure what happens if you run the same command from within the proxy host and not remotely.

 

Another option is that there is something else between you and the proxy but it sound odd.

Subject: [squid-users] Odd behavior on CNAME

 

Hi,
I have a linkchecker running over Squid as forwardproxy. One Site is not longer existing but DNS still has a CNAME Record except the CNAME is pointing nowhere:

> $ host de.sitestat.com
> de.sitestat.com is an alias for wildcard.sitestat.com.
> $ host wildcard.sitestat.com.
> $ 

If called via curl:
> $ curl --proxy forwardproxy:3128 -v http://de.sitestat.com/
> * About to connect() to proxy forwardproxy.rz.babiel.com port 3128 (#0)
> *   Trying 192.168.110.215...

> > User-Agent: curl/7.29.0
> > Host: de.sitestat.com

The connection and this curl stays open for literally infinitely. (tested for 3 days).

In the Squid access.log nothing shows up. My cache.log has:
> 2019/01/14 11:30:31 kid1| ipcacheParse: No Address records in response to 'de.sitestat.com'

Any ideas how to solve this or is this simply a bug?

Felix
