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.
