.TH SSH 1 .SH NAME ssh - secure shell remote login client .SH SYNOPSIS .B ssh [ .B -d ] [ .B -R ] [ .B -t .I thumbfile ] [ .B -u .I user ] [ .IR user @] host [ .I cmd .I args .I ... ] .SH DESCRIPTION .I Ssh starts a remote shell or .I cmd on the computer .I host logged in as .IR user . The input file descriptor is forwarded to the remote side and output and error descriptors are forwarded to the local side. .PP The connection is authenticated and encrypted using the SSH2 protocol. The user authenticates itself to the host using his RSA keypair or plaintext passwords. To authenticate the host to the user, the hosts RSA public key is hashed and compared to the entries in .B $home/lib/sshthumbs file. The thumb files location can be changed with the .B -t option. .PP When no .I cmd is specified then ssh starts a shell on the remote side. .PP If the .B $TERM environment variable is set then a pseudo terminal will be requested for the shell. This can be disabled with the .B -R option. .PP The .B -d option enables debug output. .SH SOURCE .B /sys/src/cmd/ssh.c .SH SEE ALSO .IR vt (1), .IR rsa (8), .IR factotum (4)
