Specifying "!bg sh -c" permits the process to be backgrounded and therefore does not hold up tun0 traffic and allows programs running within ppp.linkup to actually use tun0. I discovered this when attempting to run 'nsupdate' to my DNS server to notify it of my newly obtained IP. If I run it as "! sh -c", nsupdate HANGS forever. If I run it as "!bg sh -c", nsupdate performs the requested actions. I think it would be very helpful to add something into the ppp.linkup example files to indicate this. -JD >How-To-Repeat: See above >Fix: Run commands with "!bg sh -c" instead of "! sh -c" >Release-Note: >Audit-Trail: >Unformatted:
