curl/timeout issue -- OFF TOPIC!

[bruce]

Hi.

List has been rather sparse today. I have a curl issue that I thought
I'd toss out. Yes it's off topic, and yes I've posted to the curl list
as well.

The basic url operates within the browser the curl cmd generates a
timeout (7) error.

curl  --verbose -L 'https://www.saddleback.edu/' -H 'User-Agent:
Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0'
-H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'
-H 'Accept-Language: en-US,en;q=0.5' --compressed -H 'Connection:
keep-alive' --cookie-jar /crawl_tmp/a.lwp --cookie /crawl_tmp/a.lwp

thoughts??

thanks

Maybe a transient issue?  Does not timeout for me...

Browser vs command line is sometimes proxy vs no proxy, depending on 
your settings.

My go to for debugging opaque stuff like this is strace:

strace curl ........

which will at least show you the OS call that timed out - that can be 
illuminating.

Hi Cameron.

Thanks for the reply. Never really used "strace" before, but it might
be time to jump in.

A bit of background. I'm testing all of this on an older Centos 7
instance. I created the instance/droplet so I can repeatedly test on a
stable system. I have a "custom" image that Digital Image allows me to
use to quickly reproduce a base test system.

As a quick test I created a test centos 7 base droplet. It allows >>
curl -L 'www.saddleback.edu' , to run with no issues. So my probs are
self created.

If you have a few mins, the following is the strace output. I'm not
sure what I need/should be focusing on to get the 'aha!!' moment.

My assumption is that I've left something out in the creation of the
custom image. The weird thing is that as far as I know,, I'm able to
curl other sites with no issues.

Hi Cameron/List.

Regarding the Curl issue. It now appears that it's not a "Centos"
issue. It appears that the college Saddleback college is blocking
command line processes.

A conversation with their tech team said that they have gotten more
strict due to the website being hit with DDOS attacks that shut down
the site a while back.

So even though my tests weren't that extensive, they triggered the
firewall/load balancer. While the IP of AWS are recognied and has some
leeway, the  IP addresses from Digital Ocean dont get the same love.

thanks

The above forks a thread, presumably curl wants to decouple the control 
stuff from things which might block.

This kicks off a TCP connect() in nonblocking mode, courtesy of the 
fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) above it.

You should check if "209.129.85.100" is the correct IP address. And ping 
it. And see if it actually listens on port 443 (https), eg with telnet 
or nc or even nmap. It may be information to test both within your test 
environment and from outside, for comparison.

It is also making a direct HTTPS connection, not via a proxy.

Here we see curl checking on the status of the connect() operation, 
polling it once a second... The timeout is just the poll rate timeout at 
1000ms, not the connect() timeout.

Lots of that, then:
> poll([{fd=3, events=POLLOUT}], 1, 1000) = 1 ([{fd=3, revents=POLLOUT|POLLERR|POLLHUP}])
> poll([{fd=3, events=POLLOUT|POLLWRNORM}], 1, 0) = 1 ([{fd=3, revents=POLLOUT|POLLWRNORM|POLLERR|POLLHUP}])
> getsockopt(3, SOL_SOCKET, SO_ERROR, [110], [4]) = 0

Here the poll returns with some revents values instead of a poll 
timeout. You can find the meaning of these values in "man 2 poll", which 
documents the poll() system call. From the man page:

POLLOUT
      Writing is now possible, though a write larger that  the
      avail‐ able  space  in a socket or pipe will still block
      (unless O_NONBLOCK is set).
   POLLERR
      Error  condition  (only returned in revents; ignored in
      events).  This bit is also set for a  file  descriptor
      referring  to  the write end of a pipe when the read end has
      been closed.
   POLLHUP
      Hang  up  (only  returned  in revents; ignored in events).
      Note that when reading from a channel such as  a  pipe  or a
      stream socket, this event merely indicates that the peer
      closed its end of the channel.  Subsequent reads from the
      channel will return 0 (end of file) only after all outstanding
      data in the channel has been consumed.

So: an error (not curl getting bored), hang up ("this event merely 
indicates that the peer closed its end of the channel"), output now 
possible (in this case this means output will not block, because the 
connection timed out - actual output would result in an immediate 
error).

And all the following guff is curl printing the error message.

So it looks like a legitimate OS level TCP connect timeout (because poll 
returns with the error, it isn;'t some artificial limit inside curl).

So check the IP address against your target hostname (eg "host 
your-target-hostname"), and check that you can connect to that IP on 
port 443. Suspect host not listening _or_ firewall dropping 443 
connections.

Also, if you want to _measure_ how long things took to time out, 
strace's "-r" and "-t" options will include timing information in the 
output.
