The default ubuntu install has "PermitRootLogin yes " but root is not allowed
to login on the host machine. As a test, try the code on a not root account.
The sshd_config also has a "LogLevel INFO" setting that might help?
--- man sshd_conf ---
LogLevel
Gives the verbosity level that is used when logging messages from
sshd.
The possible values are:
QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2 and DEBUG3.
The default is INFO. DEBUG and DEBUG1 are equivalent. DEBUG2
and DEBUG3 each specify higher levels of debugging output.
Logging with a DEBUG level violates the privacy of users
and is not recommended.

yes...I have enabled that in the config file
PermitRootLogin yes
And if I use MS openSSH, then I am able to do a ssh to the host as root

Can you use ssh to connect as root from the host?

Hi all,
I tried JSch to scp a file to a VMware ESX 3.0 host and the session could not
be established because of
Algorithm negotiation fail

I am guessing that some tweaking to the config file should solve the issue.
Can you please throw some light on this??? Or is this configuration not
supported???
Thanks,
Pal
