[Momonga-devel.en:00017] sftp will not log user's activities???

[Nguyen Hung Vu <vuhung16yang@xxxxxxxxxxx>]

Hello,

I think this is bug likely in sshd_config. Per default
installation sshd_config will allow sftp but it does not
log sftp activities :D. So anyone can bruteforce sftp
server without fearing to be logged.

#correct me if i am wrong :D

Here is sshd_config in openssh3.6p1

# This is the sshd server system-wide configuration file. 
See
# sshd_config(5) for more information.

# This sshd was compiled with
PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config
shipped with
# OpenSSH is to specify options with their default value
where
# possible, but leave them commented.  Uncommented options
change a
# default value.

#Port 22
#Protocol 2,1
#ListenAddress 0.0.0.0
