Net_SSH2

Default Constructor.

$host can either be a string, representing the host, or a stream resource.

PHP4 compatible Default Constructor.

Set Crypto Engine Mode

Possible $engine values: CRYPT_MODE_INTERNAL, CRYPT_MODE_MCRYPT

Send Identification String First

https://tools.ietf.org/html/rfc4253#section-4.2 says "when the connection has been established, both sides MUST send an identification string". It does not say which side sends it first. In theory it shouldn't matter but it is a fact of life that some SSH servers are simply buggy

Send Identification String Last

Send SSH_MSG_KEXINIT First

https://tools.ietf.org/html/rfc4253#section-7.1 says "key exchange begins by each sending sending the [SSH_MSG_KEXINIT] packet". It does not say which side sends it first. In theory it shouldn't matter but it is a fact of life that some SSH servers are simply buggy

Connect to an SSHv2 server

Generates the SSH identifier

You should overwrite this method in your own class if you want to use another identifier

Key Exchange

Maps an encryption algorithm name to the number of key bytes.

Maps an encryption algorithm name to an instance of a subclass of \phpseclib\Crypt\Base.

Tests whether or not proposed algorithm has a potential for issues

Login

The $password parameter can be a plaintext password, a Crypt_RSA object or an array

Login Helper

Login Helper

Login via keyboard-interactive authentication

See {@link http://tools.ietf.org/html/rfc4256 RFC4256} for details. This is not a full-featured keyboard-interactive authenticator.

Handle the keyboard-interactive requests / responses.

Login with an ssh-agent provided key

Login with an RSA private key

Set Timeout

$ssh->exec('ping 127.0.0.1'); on a Linux host will never return and will run indefinitely. setTimeout() makes it so it'll timeout. Setting $timeout to false or 0 will mean there is no timeout.

Set Keep Alive

Sends an SSH2_MSG_IGNORE message every x seconds, if x is a positive non-zero number.

Get the output from stdError

Execute Command

If $callback is set to false then Net_SSH2::_get_channel_packet(NET_SSH2_CHANNEL_EXEC) will need to be called manually. In all likelihood, this is not a feature you want to be taking advantage of.

Creates an interactive shell

Return the channel to be used with read() / write()

Return an available open channel

Returns the output of an interactive shell

Returns when there's a match for $expect, which can take the form of a string literal or, if $mode == NET_SSH2_READ_REGEX, a regular expression.

Inputs a command into an interactive shell.

Start a subsystem.

Right now only one subsystem at a time is supported. To support multiple subsystem's stopSubsystem() could accept a string that contained the name of the subsystem, but at that point, only one subsystem of each type could be opened. To support multiple subsystem's of the same name maybe it'd be best if startSubsystem() generated a new channel id and returns that and then that that was passed into stopSubsystem() but that'll be saved for a future date and implemented if there's sufficient demand for such a feature.

Stops a subsystem.

Closes a channel

If read() timed out you might want to just close the channel and have it auto-restart on the next read() call

Is timeout?

Did exec() or read() return because they timed out or because they encountered the end?

Disconnect

Destructor.

Will be called, automatically, if you're supporting just PHP5. If you're supporting PHP4, you'll need to call disconnect().

Is the connection still active?

Have you successfully been logged in?

Pings a server connection, or tries to reconnect if the connection has gone down

Inspired by http://php.net/manual/en/mysqli.ping.php

In situ reconnect method

Resets a connection for re-use

Gets Binary Packets

See '6. Binary Packet Protocol' of rfc4253 for more info.

Filter Binary Packets

Because some binary packets need to be ignored...

Enable Quiet Mode

Suppress stderr from output

Disable Quiet Mode

Show stderr in output

Returns whether Quiet Mode is enabled or not

Enable request-pty when using exec()

Disable request-pty when using exec()

Returns whether request-pty is enabled or not

Gets channel data

Returns the data as a string if it's available and false if not.

Sends Binary Packets

See '6. Binary Packet Protocol' of rfc4253 for more info.

Logs data packets

Makes sure that only the last 1MB worth of packets will be logged

Sends channel data

Spans multiple SSH_MSG_CHANNEL_DATAs if appropriate

Closes and flushes a channel

Net_SSH2 doesn't properly close most channels. For exec() channels are normally closed by the server and for SFTP channels are presumably closed when the client disconnects. This functions is intended for SCP more than anything.

Disconnect

String Shift

Inspired by array_shift

Define Array

Takes any number of arrays whose indices are integers and whose values are strings and defines a bunch of named constants from it, using the value as the name of the constant and the index as the value of the constant. If any of the constants that would be defined already exists, none of the constants will be defined.

Returns a log of the packets that have been sent and received.

Returns a string if NET_SSH2_LOGGING == NET_SSH2_LOG_COMPLEX, an array if NET_SSH2_LOGGING == NET_SSH2_LOG_SIMPLE and false if !defined('NET_SSH2_LOGGING')

Formats a log for printing

Helper function for _format_log

For use with preg_replace_callback()

Helper function for agent->_on_channel_open()

Used when channels are created to inform agent of said channel opening. Must be called after channel open confirmation received

Returns the first value of the intersection of two arrays or false if the intersection is empty. The order is defined by the first parameter.

Returns all errors

Returns the last error

Return the server identification.

Return a list of the key exchange algorithms the server supports.

Return a list of the host key (public key) algorithms the server supports.

Return a list of the (symmetric key) encryption algorithms the server supports, when receiving stuff from the client.

Return a list of the (symmetric key) encryption algorithms the server supports, when sending stuff to the client.

Return a list of the MAC algorithms the server supports, when receiving stuff from the client.

Return a list of the MAC algorithms the server supports, when sending stuff to the client.

Return a list of the compression algorithms the server supports, when receiving stuff from the client.

Return a list of the compression algorithms the server supports, when sending stuff to the client.

Return a list of the languages the server supports, when sending stuff to the client.

Return a list of the languages the server supports, when receiving stuff from the client.

Returns a list of algorithms the server supports

Returns a list of KEX algorithms that phpseclib supports

Uses the same format as https://www.php.net/ssh2-methods-negotiated

Accepts an associative array with up to four parameters as described at https://www.php.net/manual/en/function.ssh2-connect.php

Returns the banner message.

Quoting from the RFC, "in some jurisdictions, sending a warning message before authentication may be relevant for getting legal protection."

Returns the server public host key.

Caching this the first time you connect to a server and checking the result on subsequent connections is recommended. Returns false if the server signature is not signed correctly with the public host key.

Returns the exit status of an SSH command or false.

Returns the number of columns for the terminal window size.

Returns the number of rows for the terminal window size.
