spicec [-h, --host <host>] [-p, --port <port>] [-s, --secure-port <port>] [--secure-channels <ch0, ch1...>] [--unsecure-chan- nels <ch0, ch1...>] [-w, --password <password>] [-f, --full-screen[=auto-conf]] [--canvas-type <type1, type2...>] [--enable-chan- nels <ch0, ch1...>] [--disable-channels <ch0, ch1...>] [--help] DESCRIPTION
spicec is a Spice client, it can be used to connect to Spice server, such as spice compatible QEMU OPTIONS
-h, --host <host> Spice server address. -p, --port <port> Spice server port -s, --secure-port <port> Spice server secure port --secure-channels <ch0, ch1...> Force secure connection on the specified channels Channels are: main, display, inputs, cursor, playback and record By default, any channel can be secured, depending on the --secure-port availability. --unsecure-channels <ch0, ch1...> Force unsecure connection on the specified channels Channels are: main, display, inputs, cursor, playback and record. By default, any channel can be unsecured, depending on the --port availability. -w, --password <password> Set a ticketing password (default is none) -s, --secure-port <port> Spice server secure port -f, --full-screen[=auto-conf] Open in a full screen mode. Optional automatic configuration of the remote display settings according to the client display set- tings. A guest agent must be installed and started for this option. --canvas-type <type1, type2...> Select the available renderer. The order determines precedence For Linux client : only "cairo" canvas type is available. For Win- dows client : available types are "gdi" and "cairo". The default is "gdi". --enable-channels <ch0, ch1...> Enable the specified channels. Use "all" for enabling all possible channels. Use the following names for enabling only the selected channels: "display", "inputs", "cursor", "playback" and "record". By default all channels are enabled. --disable-channels <ch0, ch1...> Disable the specified channels. Use "all" for disabling all possible channels. Use the following names for enabling only the selected channels: "display", "inputs", "cursor", "playback" and "record." By default all channels are enabled. --help Show command help. CONTROL HOT KEYS
Shift + F11 Toggle full-screen / window mode Shift + F12 Release the cursor if captured in window On debug mode, these are available as well: Shift + F5 Connect to the server Shift + F6 Disconnect from the server SEE ALSO

socket(n) Tcl Built-In Commands socket(n) __________________________________________________________________________________________________________________________________________________ NAME
socket - Open a TCP network connection SYNOPSIS
socket ?options? host port socket -server command ?options? port _________________________________________________________________ DESCRIPTION
This command opens a network socket and returns a channel identifier that may be used in future invocations of commands like read, puts and flush. At present only the TCP network protocol is supported; future releases may include support for additional protocols. The socket command may be used to open either the client or server side of a connection, depending on whether the -server switch is specified. CLIENT SOCKETS
If the -server option is not specified, then the client side of a connection is opened and the command returns a channel identifier that can be used for both reading and writing. Port and host specify a port to connect to; there must be a server accepting connections on this port. Port is an integer port number and host is either a domain-style name such as www.sunlabs.com or a numerical IP address such as 127.0.0.1. Use localhost to refer to the host on which the command is invoked. The following options may also be present before host to specify additional information about the connection: -myaddr addr Addr gives the domain-style name or numerical IP address of the client-side network interface to use for the connection. This option may be useful if the client machine has multiple network interfaces. If the option is omitted then the client-side interface will be chosen by the system software. -myport port Port specifies an integer port number to use for the client's side of the connection. If this option is omitted, the client's port number will be chosen at random by the system software. -async The -async option will cause the client socket to be connected asynchronously. This means that the socket will be created immedi- ately but may not yet be connected to the server, when the call to socket returns. When a gets or flush is done on the socket before the connection attempt succeeds or fails, if the socket is in blocking mode, the operation will wait until the connection is com- pleted or fails. If the socket is in nonblocking mode and a gets or flush is done on the socket before the connection attempt suc- ceeds or fails, the operation returns immediately and fblocked on the socket returns 1. SERVER SOCKETS
If the -server option is specified then the new socket will be a server for the port given by port. Tcl will automatically accept connec- tions to the given port. For each connection Tcl will create a new channel that may be used to communicate with the client. Tcl then invokes command with three additional arguments: the name of the new channel, the address, in network address notation, of the client's host, and the client's port number. The following additional option may also be specified before host: -myaddr addr Addr gives the domain-style name or numerical IP address of the server-side network interface to use for the connection. This option may be useful if the server machine has multiple network interfaces. If the option is omitted then the server socket is bound to the special address INADDR_ANY so that it can accept connections from any interface. Server channels cannot be used for input or output; their sole use is to accept new client connections. The channels created for each incoming client connection are opened for input and output. Closing the server channel shuts down the server so that no new connections will be accepted; however, existing connections will be unaffected. Server sockets depend on the Tcl event mechanism to find out when new connections are opened. If the application doesn't enter the event loop, for example by invoking the vwait command or calling the C procedure Tcl_DoOneEvent, then no connections will be accepted. CONFIGURATION OPTIONS
The fconfigure command can be used to query several readonly configuration options for socket channels: | -error | This option gets the current error status of the given socket. This is useful when you need to determine if an asynchronous connect | operation succeeded. If there was an error, the error message is returned. If there was no error, an empty string is returned. -sockname This option returns a list of three elements, the address, the host name and the port number for the socket. If the host name cannot be computed, the second element is identical to the address, the first element of the list. -peername This option is not supported by server sockets. For client and accepted sockets, this option returns a list of three elements; these are the address, the host name and the port to which the peer socket is connected or bound. If the host name cannot be computed, the second element of the list is identical to the address, its first element. SEE ALSO
