[asterisk-commits] russell: branch 1.8 r353077 - /branches/1.8/main/netsock.c

[SVN commits to the Asterisk project]

Author: russell

New Revision: 353077

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=353077
Log:
Update ast_set_default_eid() to find more network interfaces.

As of Fedora 15, ethN is not the name of ethernet interfaces.  The names
are emN or pciN.  Update some code that searched for interfaces named
ethN to look for the new names, as well.  For more information about why
this change was made, see this page:
