| __construct($host, $port = 22, $timeout = 10, $cipher = self::CIPHER_3DES) X-Ref |
| Default Constructor. Connects to an SSHv1 server return: \phpseclib\Net\SSH1 param: string $host param: int $port param: int $timeout param: int $cipher |
| _connect() X-Ref |
| Connect to an SSHv1 server return: bool |
| login($username, $password = '') X-Ref |
| Login return: bool param: string $username param: string $password |
| setTimeout($timeout) X-Ref |
| 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. param: mixed $timeout |
| exec($cmd, $block = true) X-Ref |
| Executes a command on a non-interactive shell, returns the output, and quits. An SSH1 server will close the connection after a command has been executed on a non-interactive shell. SSH2 servers don't, however, this isn't an SSH2 client. The way this works, on the server, is by initiating a shell with the -s option, as discussed in the following links: {@link http://www.faqs.org/docs/bashman/bashref_65.html http://www.faqs.org/docs/bashman/bashref_65.html} {@link http://www.faqs.org/docs/bashman/bashref_62.html http://www.faqs.org/docs/bashman/bashref_62.html} To execute further commands, a new \phpseclib\Net\SSH1 object will need to be created. Returns false on failure and the output, otherwise. see: self::interactiveRead() see: self::interactiveWrite() return: mixed param: string $cmd |
| _initShell() X-Ref |
| Creates an interactive shell see: self::interactiveRead() see: self::interactiveWrite() return: bool |
| write($cmd) X-Ref |
| Inputs a command into an interactive shell. see: self::interactiveWrite() return: bool param: string $cmd |
| read($expect, $mode = self::READ_SIMPLE) X-Ref |
| Returns the output of an interactive shell when there's a match for $expect $expect can take the form of a string literal or, if $mode == self::READ_REGEX, a regular expression. see: self::write() return: bool param: string $expect param: int $mode |
| interactiveWrite($cmd) X-Ref |
| Inputs a command into an interactive shell. see: self::interactiveRead() return: bool param: string $cmd |
| interactiveRead() X-Ref |
| Returns the output of an interactive shell when no more output is available. Requires PHP 4.3.0 or later due to the use of the stream_select() function. If you see stuff like "^[[00m", you're seeing ANSI escape codes. According to {@link http://support.microsoft.com/kb/101875 How to Enable ANSI.SYS in a Command Window}, "Windows NT does not support ANSI escape sequences in Win32 Console applications", so if you're a Windows user, there's not going to be much recourse. see: self::interactiveRead() return: string |
| disconnect() X-Ref |
| Disconnect |
| __destruct() X-Ref |
| Destructor. Will be called, automatically, if you're supporting just PHP5. If you're supporting PHP4, you'll need to call disconnect(). |
| _disconnect($msg = 'Client Quit') X-Ref |
| Disconnect param: string $msg |
| _get_binary_packet() X-Ref |
| Gets Binary Packets See 'The Binary Packet Protocol' of protocol-1.5.txt for more info. Also, this function could be improved upon by adding detection for the following exploit: http://www.securiteam.com/securitynews/5LP042K3FY.html see: self::_send_binary_packet() return: array |
| _send_binary_packet($data) X-Ref |
| Sends Binary Packets Returns true on success, false on failure. see: self::_get_binary_packet() return: bool param: string $data |
| _crc($data) X-Ref |
| Cyclic Redundancy Check (CRC) PHP's crc32 function is implemented slightly differently than the one that SSH v1 uses, so we've reimplemented it. A more detailed discussion of the differences can be found after $crc_lookup_table's initialization. see: self::_get_binary_packet() see: self::_send_binary_packet() return: int param: string $data |
| _string_shift(&$string, $index = 1) X-Ref |
| String Shift Inspired by array_shift return: string param: string $string param: int $index |
| _rsa_crypt($m, $key) X-Ref |
| RSA Encrypt Returns mod(pow($m, $e), $n), where $n should be the product of two (large) primes $p and $q and where $e should be a number with the property that gcd($e, ($p - 1) * ($q - 1)) == 1. Could just make anything that calls this call modexp, instead, but I think this makes things clearer, maybe... see: self::__construct() return: BigInteger param: BigInteger $m param: array $key |
| _define_array() X-Ref |
| 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. param: array $array |
| getLog() X-Ref |
| Returns a log of the packets that have been sent and received. Returns a string if NET_SSH1_LOGGING == self::LOG_COMPLEX, an array if NET_SSH1_LOGGING == self::LOG_SIMPLE and false if !defined('NET_SSH1_LOGGING') return: array|false|string |
| _format_log($message_log, $message_number_log) X-Ref |
| Formats a log for printing return: string param: array $message_log param: array $message_number_log |
| _format_log_helper($matches) X-Ref |
| Helper function for _format_log For use with preg_replace_callback() return: string param: array $matches |
| getServerKeyPublicExponent($raw_output = false) X-Ref |
| Return the server key public exponent Returns, by default, the base-10 representation. If $raw_output is set to true, returns, instead, the raw bytes. This behavior is similar to PHP's md5() function. return: string param: bool $raw_output |
| getServerKeyPublicModulus($raw_output = false) X-Ref |
| Return the server key public modulus Returns, by default, the base-10 representation. If $raw_output is set to true, returns, instead, the raw bytes. This behavior is similar to PHP's md5() function. return: string param: bool $raw_output |
| getHostKeyPublicExponent($raw_output = false) X-Ref |
| Return the host key public exponent Returns, by default, the base-10 representation. If $raw_output is set to true, returns, instead, the raw bytes. This behavior is similar to PHP's md5() function. return: string param: bool $raw_output |
| getHostKeyPublicModulus($raw_output = false) X-Ref |
| Return the host key public modulus Returns, by default, the base-10 representation. If $raw_output is set to true, returns, instead, the raw bytes. This behavior is similar to PHP's md5() function. return: string param: bool $raw_output |
| getSupportedCiphers($raw_output = false) X-Ref |
| Return a list of ciphers supported by SSH1 server. Just because a cipher is supported by an SSH1 server doesn't mean it's supported by this library. If $raw_output is set to true, returns, instead, an array of constants. ie. instead of array('Triple-DES in CBC mode'), you'll get array(self::CIPHER_3DES). return: array param: bool $raw_output |
| getSupportedAuthentications($raw_output = false) X-Ref |
| Return a list of authentications supported by SSH1 server. Just because a cipher is supported by an SSH1 server doesn't mean it's supported by this library. If $raw_output is set to true, returns, instead, an array of constants. ie. instead of array('password authentication'), you'll get array(self::AUTH_PASSWORD). return: array param: bool $raw_output |
| getServerIdentification() X-Ref |
| Return the server identification. return: string |
| _append_log($protocol_flags, $message) X-Ref |
| Logs data packets Makes sure that only the last 1MB worth of packets will be logged param: string $data |
