FILES
       lshd doesn't use any traditional configuration file, but must have a random seed file and the server key.  By default

       /var/spool/lsh/yarrow-seed-file

       is used as random seed file (see ENVIRONMENT for changing this) and

       /etc/lsh_host_key

       is the default key file.

       /var/run/lshd.pid

       is used to store the process id of the server by default.

       Authorized keys are stored in the directory

       $HOME/.lsh/authorized_keys_sha1/

DIAGNOSTICS
       Log messages are normally sent to syslog(3) when running in daemonic mode.

       See the --verbose , --trace and --debug options.

REPORTING BUGS
       Report bugs to <bug-lsh@gnu.org>.

ENVIRONMENT
       LSH_YARROW_SEED_FILE may be used to specify the random seed file.

       lshd mimics OpenSSH behaviour with respect to SSH_CLIENT and SSH_TTY for processes it starts where applicable.
