I am glad to announce CT console feature.
Very cool - been on my wish list for a while!
Available in RHEL6-based kernel since 042stab048.1, this feature is
pretty simple to use. Use vzctl attach CTID to attach to this
container's console, and you will be able to see all the messages CT
init is writing to console, or run getty on it, or anything else.
Please note that the console is persistent, i.e. it is available even
if a container is not running. That way, you can run vzctl attach and
then (in another terminal) vzctl start. That also means that if a
container is stopped, vzctl attach is still there.
Press Esc . to detach from the console.
Cool. Just a thought on this escape sequence... ipmitool and ssh
(amongst others) use ~ after a carriage return as the command sequence,
and this is sort-of a defacto standard...
OpenSSH..
tim@ermintrude:~$ ~?
Supported escape sequences:
~. - terminate connection (and any multiplexed sessions)
[....]
~? - this message
~~ - send the escape character by typing it twice
(Note that escapes are only recognized immediately after newline.)
ipmitool
Special escape sequences are provided to control the SOL session:
~. Terminate connection
~^Z Suspend ipmitool
~^X Suspend ipmitool, but don't
restore tty on restart
~B Send break
~~ Send the escape character by
typing it twice
~? Print the supported escape sequences
Note that escapes are only recognized immediately
after newline.
Both allow you do change the escape character with a command line switch.
Any chance of adopting this "standard" instead of something else?
Any thoughts?
See, the problem here is you usually access your node through ssh, and
if we will use the same sequence than ssh will close.
Having said that, I welcome patches that
- make accept the sequence only after a newline
- make an option and/or config parameter to change Esc to something else
Cheers,
Tim.
