RE: Running host IP

[Dennis, Richard]

Sorry, nevermind, I figured out how to get this done.  I created a module
"module:getLocalIP" to provide the local ip.  I'm including it in this mail
just in case someone else runs accross the same issue w/ their linux
systems.

--Rick

#!/bin/sh
# Module:getLocalIP
# $Id$
#
IPADDR=`/sbin/ifconfig eth0 | awk '/inet addr/{print $2}' | sed 's/addr://'`
echo "=MyIP="$IPADDR


And then just put this in my config:

editfiles:
   { /etc/hosts
        BeginGroupIfNoSuchLine "127.0.0.1       localhost.localdomain
localhost"
                CommentLinesStarting   "127.0.0.1"
                InsertLine "127.0.0.1       localhost.localdomain localhost"
        EndGroup
        BeginGroupIfNoSuchLine "$(MyIP)           $(host)"
                CommentLinesStarting   "$(MyIP)"
                InsertLine "$(MyIP)           $(host)"
        EndGroup
   }

Subject: Running host IP


Is there a variable or a simple way to get the ip of eth0 (or main
interface) into a cfengine variable?

Linux has issues when the hostname is put in the 127.0.0.1 line rather than
it's real interface's ip and hostname.  What I'm trying to do is comment out
existing wrong 127.0.0.1 lines, and create a proper one.

editfiles:
   { /etc/hosts
        BeginGroupIfNoSuchLine "127.0.0.1       localhost.localdomain
localhost"
                CommentLinesStarting   "127.0.0.1"
                InsertLine "127.0.0.1       localhost.localdomain localhost"
                InsertLine "$(some_variable)           $(host)"
        EndGroup
   }
