Re: mkiss in ubuntu kernels?

["David A. Ranch" <dranch@trinnet.net>]

I hope those patches make it upstream and into the main kernel sources.
 Until that day comes, I had similar problems for bringing up a JNOS
setup.  I hacked it in using net2kiss and some kludges in my init scripts:


   #start net2kiss
   PTSRPORT=`/usr/sbin/net2kiss -i sm1 /dev/ptmx &`
   PTSPORT=`echo $PTSRPORT | awk -F / '{print $4}'`
   echo -en "[net2kiss on /dev/pts/$PTSPORT ] "


Hope this helps someone
