sftp running in chroot env
I've configured sftp to run in a chroot env which seems to work
however I am unable to get syslog to log the sftp activities within
the chroot.


If I connect via sftp to a non-chroot env the daemon will log the
transactions as expected:

i.e.

Feb 11 10:35:20 XXXXXXXXXX sftp-server[11797]: [ID 800047 auth.info]
open "/home/someguy/test/file" flags READ mode 0666



I also need the activities to be logged from within the chroot - can
someone please give me some pointers?



Here is my config running under Solaris 10:




syslog.conf:
auth.debug /var/adm/openssh.log


sshd_config:
SyslogFacility AUTH
LogLevel DEBUG
Subsystem sftp /opt/openssh/libexec/sftp-server -l DEBUG

Match User sample
ChrootDirectory /home/chroot



chroot env:

/home/chroot:

Not 100% solution is:
https://bugzilla.mindrot.org/show_bug.cgi?id=1636
the log stop working when the syslog daemon is reloaded :(
