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.
