Mode with confirmation required before slave connections are accepted.Īdditionally, for protocol version 2 a comma-separated list of MAC This also may be specified on a per-host basis in the configuration file. Specifies the user to log in as on the remote machine. Port forwardings can also be specified in the configuration file. Port : host : hostport Specifies that the given port on the local (client) host is to beįorwarded to the given host and port on the remote side.Ĭonnection is forwarded over the secure channel, and a connection is Will also try to load certificate information from the filename obtainedĮnables GSSAPI-based authentication and forwarding (delegation) of GSSAPIĭisables forwarding (delegation) of GSSAPI credentials to the server.

The recommended way to start X11 programs at a remote site is with Is going to ask for passwords or passphrases, but the user To go to background just before command execution. The default for the per-user configuration file is If a configuration file is given on the command line, Specifies an alternative per-user configuration file.

Whenever a connection is made to this port, theĬonnection is forwarded over the secure channel, and the application On the local side, optionally bound to the specified This works by allocating a socket to listen to Protocol version 1 allows specification of a single cipher. Selects the cipher specification for encrypting the session. The default value can be set on a host-by-host basis in the Slow connections, but will only slow down things on fast networks. The compression algorithm is the same used byĬompression is desirable on modem lines and other Requests compression of all data (including stdin, stdout, stderr, and Only useful on systems with more than one address.
