I only know qjail (I'm running on 9.2 release) with that setup you can...

SSH into the main host in the usual way, then
# su - root     (& enter the realy serious password etc.)

# qjail console ~jailname~

Where ~jailname~ is the name of the target jail..   And you're in, as though you 
SSH'd there to it's IP address as it's root..

^d (Ctrl+D) gets you out of there when done, returning you to the host root 

Again (I only know QJail, I think other jail topologies allow the same or similar) 
you can login to the main host, and as root, navigate to the jail directories to 
examine logfiles and so on.  In essance to "reach into a jail" from the host.   
(Obviously, care is needed, if you ever suspect any "funny business" has been 
going on!)
