Hi,

I have configured a vkernel with SSH support over IPv6 and wanted to 
access it remotely, remote access it working fine but I can't go back to 
host machine prompt without halting the vkernel, is there any way to run 
a vkernel as a background process




Alternatively, you could use tmux, so that once the vkernel is running 
you can open a new window for a new connection to the host machine.

Hi,

Thank you Matt and Antonio. I am using csh and 'notty -12
./boot/kernel/kernel -m 128m -r /var/vkernel/rootimg.01 -I auto:bridge0 >&
/tmp/log' worked for me. It's really good to know that vkernels can be
started from rc.conf, I'll try it as my next step :)

Thanks & Regards,

Hi,

vkernels can be started from rc.conf. Please check  
/etc/defaults/rc.conf to see the options.

That's with csh or tcsh . With sh it would be notty -12 blsahblahblbha  >
/tmp/logfile 2>&1

And then see what error you are getting.

Try redirecting stdout and stderr to a file.   notty -12 blahblahblabhalh
>& /tmp/logfile

That's with csh or tcsh . With sh it would be notty -12 blsahblahblbha  >
/tmp/logfile 2>&1

And then see what error you are getting.

Hi Matt,

Thanks for the information, unfortunately it did not worked for me, do I
need to change anything on vkernel's /etc/ttys file to get it worked. Sorry
if it's a silly question, I am really new to BSD.

You should be able to run the vkernel without a tty by using 'notty'
instead of 'nohup'.  It will fork and run detached, and then you can ssh
into it.
