hi,

i'm a new user and thank you for this wonderful tool !

I tried a simple loop example, and was able to successfully recreate the
demo. Then I tried sshd, and things didnt work..

I had logged in using ssh and just the session was running. then i tried
these commands
./crtools dump -x -n pid -n ipc -n net --tcp-established -vvvv -D <mydir>
-o dump.logs -t <pid> -l
that worked ok

session was paused. then i tried restoring.

./crtools restore -x -n pid -n ipc -n net --tcp-established -vvvv -D
<mydir> -o dump.logs -t <pid> -l -d

that didnt work. last lines in dump.logs were
