.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.
