[jira] Commented: (TS-355) Autodetect default network interface

["Mladen Turk (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12868125#action_12868125 ] 

Mladen Turk commented on TS-355:
--------------------------------

More correct Linux script
/sbin/ifconfig | sed 's/^ *$/CRLF/g' | tr '\n' ' ' | sed 's/CRLF /\n/g' | grep -v LOOPBACK | grep 'UP.*RUNNING' | head -1 | awk '{print $1;}'
Complex because info spreads across multiple lines, so we create one line for each iface block and then grep 

For Solaris, BSD, Mac
/sbin/ifconfig -a | grep 'UP.*RUNNING' | grep -v LOOPBACK | head -1 | awk -F: '{ print $1;}'

> Currently we instruct the user to specify the cluster interface as part of build procedure (see INSTALL)
> We can detect the interface automatically on some platforms
> Linux
> /sbin/ifconfig -a | grep ^e.* | head -1 | awk '{print $1;}'
> Solaris, FreeBsd (probably OSX)
> /sbin/ifconfig -a | grep -v LOOPBACK | grep UP | head -1 | awk -F: '{print $1;}'
> Additional configure option (--with-cluster-interface=IFACE) can be added to explicitly
> specify some other interface.
