[pdftex] Bug report - pdflatex hangs when internet connection is on

[Antonio DiCesare]

Dear All,

I'm using TeXLive 2016. When I run pdflatex (both from command line and using TeXworks) it hangs about 20-30 seconds before the compilation starts.

It happens only when the internet connection is active. When internet is off, the compilation starts immediately.

I am willing to provide you with any detail you may need.

Hope you can help to solve this boring issue.

Kind regards,
Antonio.

Hi Antonio, pdftex doesn't do anything on the network itself. Thus I
wonder if it's a matter of some antivirus program working differently
when the Internet is on, or some other difference in system
operations. Unfortunately I can't guess how to proceed. --best, karl.
