SYNOPSIS
lshd [OPTION...]
DESCRIPTION
CAUTION! The information in this manpage may be invalid or outdated. For authorative information on lsh, please see it's Texinfo manual (see the SEE ALSO section). lshd is a server for the SSH-2 (secsh) protocol.
OPTIONS
Miscellaneous options: -h, --host-key=Key file Location of the server's private key. --interface=interface Listen on this network interface. -p, --port=Port Listen on this port. --debug Print huge amounts of debug information --log-file=File name Append messages to this file. -q, --quiet Suppress all warnings and diagnostic messages --trace Detailed trace -v, --verbose Verbose diagnostic messages Algorithm selection: -c, --crypto=Algorithm --hostkey-algorithm=Algorithm --list-algorithms List supported algorithms. -m, --mac=Algorithm -z, --compression[=Algorithm] Default is zlib. --banner-file=File name Banner file to send before handshake. Keyexchange options: --dh-keyexchange Enable DH support (default). --no-dh-keyexchange Disable DH support. --no-srp-keyexchange Disable experimental SRP support (default). --srp-keyexchange Enable experimental SRP support. User authentication options: --kerberos-passwords Recognize kerberos passwords, using the helper program "/usr/local/sbin/lsh-krb- checkpw". This option is experimental. --login-auth-mode Enable a telnet like mode (accept none-authentication and launch thelogin-shell, making it responsible for authenticating the user). --login-shell=Program Use this program as the login shell for all users. (Experimental) --no-kerberos-passwords Don't recognize kerberos passwords (default behaviour). --no-login-auth-mode Disable login-auth-mode (default). --no-password Disable password user authentication. --no-publickey Disable publickey user authentication. --no-root-login Don't allow root to login (default). --password Enable password user authentication (default). --password-helper=Program Use the named helper program for password verification. (Experimental). --publickey Enable publickey user authentication (default). --root-login Allow root to login. Offered services: --no-pty-support Disable pty allocation. --no-tcpip-forward Disable tcpip forwarding. --no-x11-forward Disable x11 forwarding. --pty-support Enable pty allocation (default). --subsystems=List of subsystem names and programs For example `sftp=/usr/sbin/sftp-server,foosystem=/usr/bin/foo' (experimental). --tcpip-forward Enable tcpip forwarding (default). --x11-forward Enable x11 forwarding (default). Options controlling daemonic mode and related options: --daemonic Run in the background, redirect stdio to /dev/null, and chdir to /. --enable-core Dump core on fatal errors (disabled by default). --no-daemonic Run in the foreground, with messages to stderr (default). --no-pid-file Don't use any pid file. Default in non-daemonic mode. --no-syslog Don't use syslog (by default, syslog is used when running in daemonic mode). --pid-file=file name Create a pid file. When running in daemonic mode, the default is /var/run/lshd.pid. -?, --help Give this help list --usage Give a short usage message -V, --version Print program version Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
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.
