Description Erwan LE PENNEC 2015-06-23 08:12:32 UTC

Description of problem:

Since a few days, startDynamicHelp does not work anymore and complains about a socket issue.

> tools::startDynamicHelp()
starting httpd help server ...Error in tools::startDynamicHelp() : 
  unable to bind socket to TCP port 18159

Disabling the firewall or selinux, or using R as root does not fix the issue

Version-Release number of selected component (if applicable):
3.2.1
3.2.0


How reproducible:

This bug appears using Rstudio but is visible using the standalone R version (3.2.1 and 3.2.0)

Steps to Reproduce:

> tools::startDynamicHelp()
starting httpd help server ...Error in tools::startDynamicHelp() : 
  unable to bind socket to TCP port 18159

Expected results:

No socket errors

Additional info:

Used to work until a few days.
I'm using update-testing...

This issue is caused by NetworkManager who fails to mount the loopback interface:
