-l login_name | Specifies the user for login to the remote system (same as login_name@host). |
+x | Enables X11 port forwarding. Treats X11 clients as "untrusted." |
+X | Enables X11 port forwarding. Treats X11 clients as "trusted." |
-x | Disables X11 port forwarding. |
-i file | Specifies the identity file for public-key authentication. This
option takes the file name as a parameter. It is assumed that the file resides
in the user's [.SSH2] directory. This option can also be specified in the
configuration file. |
-F file | Specifies an alternative client host configuration file instead
of the default file. The specified file name must include the directory where
the file resides (for example,: [.SSH2]MY_SSH2_CONFIG). Information from
this file supersedes information from TCPIP$SSH_DEVICE:[TCPIP$SSH]SSH2_CONFIG.
and the user's [.SSH2]SSH2_CONFIG. file. |
-t | Allocates a terminal device to the process. |
-v | Enables verbose mode. Displays verbose debugging messages. Equivalent
to the -d2 option. This option can also be specified in
the client's configuration file. |
-d debug-level | Displays debug information. The debug-level value
is a number from 0 to 99, where 99 specifies that all debug information or
a comma-separated list of assignments should be displayed. |
-V | Displays the version of SSH. |
-q | Disables warning messages. This option can also be specified
in the client's configuration file. |
-p port | Specifies the port to which to connect on the remote system. |
-S | Does not request a session channel. This type of session does
not disconnect automatically. To disconnect a session begun with this option,
enter the following TCP/IP Management command: $ TCPIP DISCONNECT DEVICE BGnnnn |
Where
BGnnnn is the SSH session's device socket, as displayed
by the TCP/IP management command SHOW DEVICE. |
-L [protocol/] port:host:hostport | Specifies that the given port on the local (client) system is to be
forwarded to the specified host and port on the remote system. This allocates
a socket to listen to the port on the local system. Whenever a connection
is made to this port, the connection is forwarded over the secure channel,
and a connection is made to the specified host on the specified port from
the remote system. Only privileged user accounts can forward privileged ports.
The protocol enables the forwarding for the specfied protocol. The protocols
implemented are TCP and FTP; the default is no specific processing. Temporary
forwardings are created for the FTP data channel, effectively securing the
whole FTP session. This option can also be specified in the client configuration
file (see Appendix B). FTP data channel
forwarding works in passive mode only. Be sure to set passive mode for FTP
data channel connections. |
-R [protocol/] port:host:hostport | Specifies that the given port on the remote (server) system is to be
forwarded to the specified host and port on the local system. This allocates
a socket to listen to the port on the remote system. Whenever a connection
is made to this port, the connection is forwarded over the secure channel,
and a connection is made to the specified host and port from the local system.
Only privileged user accounts can forward privileged ports on the remote
system. The protocol argument enables protocol-specific forwarding. The protocols
implemented are TCP and FTP; the default is no specific processing. Temporary
forwardings are created for FTP data channel, effectively securing the whole
FTP session. This option can also be specified in the client's configuration
file (see Appendix B). |
-4 | Restricts communications to IPv4. |
-6 | Enables IPv6 networking. |
-o option | Specifies an option in the format used in the SSH2_CONFIG. configuration
file. This is useful for specifying an option for which there is no command-line
option. Comment lines are not accepted with this option. |
-h | Displays information about using the SSH utility. |
