HI
All
I have patched my linux host for ska3 and it can run under skas3 mode. However, when I gdb linux
i. I want to follow
r ubd0=/home/jdike/roots/cow.debian,/home/jdike/roots/debian_22 con=port:9000 ssl=pty con0=fd:0,fd:1 umid=debian mem=128M

however, I do not the meaning of ubd0 ,since there is no cow.debian under my roots. I really do not know how to set these parameters.

So , I just put (after setting handle two signals)
r
It comes out
