#8398: res_query warning in torsocks
--------------------------------+-------------------------------------------
Reporter: zqcxobbe | Owner: ioerror
Type: defect | Status: needs_information
Priority: minor | Milestone:
Component: Torsocks | Version:
Keywords: torsocks res_query | Parent:
Points: | Actualpoints:
--------------------------------+-------------------------------------------
Comment(by zqcxobbe):
I replaced a torproject.org DNS by <DNS1> and two IPs by <IP1> and <IP2>
in the output of run_tests.sh.
Just like before, I have no idea of what tsocks_init is. I also see the
gethostbyname thing in the output. What that means beats me. Let me know
what I can do for you.
Output of aptitude
$PS1 > sudo aptitude
This is uwt /usr/local/bin/aptitude wrapper.
