lsh

lsh is a free software implementation of the Secure Shell (SSH) protocol version 2, by the GNU Project[2][3][4][5] including both server and client programs. Featuring Secure Remote Password protocol (SRP) as specified in secsh-srp[6][7] besides, public-key authentication. Kerberos is somewhat supported as well. Currently however for password verification only, not as a single sign-on (SSO) method.

lsh was started from scratch and predates OpenSSH.[8]

Karim Yaghmour concluded in 2003 that lsh was "not fit for use" in production embedded Linux systems, because of its dependencies upon other software packages that have a multiplicity of further dependencies. The lsh package requires the GNU MP library, zlib, and liboop, the latter of which in turn requires GLib, which then requires pkg-config. Yaghmour further notes that lsh suffers from cross-compilation problems that it inherits from glib. "If […] your target isn't the same architecture as your host," he states, "LSH isn't a practical choice at this time."[9]

Debian provides packages of lsh as lsh-server,[10] lsh-utils, lsh-doc and lsh-client.[11]
