Heya,

Greetings from #404Lab in Tunis, Tunisia!

I'm testing the ooniprobe in the censorship lab. I'm making a running
list of issues and I'll outline them below.

When running the following test:

 ./bin/ooniprobe -l tunisia-404lab-netcache-000.log
nettests/blocking/http_requests.py;

I find that the test hangs for ~10 minutes:

...

I'm not clear what will happen next - it just hangs. I killed it after
around ten minutes.

I followed up with the following test:

./bin/ooniprobe -l tunisia-404lab-netcache-000.log
nettests/manipulation/http_invalid_request_line.py;

It worked without issues.

The following test goes on for a while:

./bin/ooniprobe -l tunisia-404lab-netcache-000.log
nettests/blocking/http_requests.py -f inputs/top-1000.txt

It starts throwing the following errors:

It then hangs like so:

[D] Checking all tasks for completion 102 == 133
[D] Successfully performed report <ooni.tasks.ReportEntry object at
0xc1405d0>
[D] None
[D] Checking all tasks for completion 103 == 133
[D] Successfully performed report <ooni.tasks.ReportEntry object at
0xc1408d0>
[D] None

I killed it - I'm not sure why it hangs. The host list is just the top
alexa hosts.

 % ./bin/ooniprobe -l tunisia-404lab-netcache-000.log
nettests/blocking/tcpconnect.py -f inputs/top-1000-port80.txt

This worked without issue.

I tried:

 % ./bin/ooniprobe -l tunisia-404lab-netcache-000.log
nettests/blocking/http_requests.py -f inputs/top-1000.txt

I had similar hangs - so the tests never finished:

[D] Checking all tasks for completion 100 == 133
[D] Successfully performed report <ooni.tasks.ReportEntry object at
0xcc7d190>
[D] None
[D] Checking all tasks for completion 101 == 133

[D] Checking all tasks for completion 102 == 133
[D] Successfully performed report <ooni.tasks.ReportEntry object at

[D] None
[D] Checking all tasks for completion 103 == 133
[D] Successfully performed report <ooni.tasks.ReportEntry object at
0xcc7da90>
[D] None

Thoughts?

All the best,
Jake
