| __construct($host, $port = 22, $timeout = 10, $cipher = self::CIPHER_3DES) X-Ref |
| Default Constructor. Connects to an SSHv1 server param: string $host param: int $port param: int $timeout param: int $cipher return: \phpseclib\Net\SSH1 |
| _connect() X-Ref |
| Connect to an SSHv1 server return: bool |
| login($username, $password = '') X-Ref |
| Login param: string $username param: string $password return: bool |
| setTimeout($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() param: string $cmd return: mixed |
| _initShell() X-Ref |
| Creates an interactive shell see: self::interactiveRead() see: self::interactiveWrite() return: bool |
| write($cmd) X-Ref |
| Inputs a command into an interactive shell. see: self::interactiveWrite() param: string $cmd return: bool |
| read($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() param: string $expect param: int $mode return: bool |
| interactiveWrite($cmd) X-Ref |
| Inputs a command into an interactive shell. see: self::interactiveRead() param: string $cmd return: bool |
| interactiveRead() X-Ref |
| Returns the output of an interactive shell when no more output is available. Requires PHP 4.3.0 or later due to the use of the stream_select() function. If you see stuff like "^[[00m", you're seeing ANSI escape codes. According to {@link http://support.microsoft.com/kb/101875 How to Enable ANSI.SYS in a Command Window}, "Windows NT does not support ANSI escape sequences in Win32 Console applications", so if you're a Windows user, there's not going to be much recourse. see: self::interactiveRead() return: string |
| disconnect() X-Ref |
| Disconnect |
| __destruct() X-Ref |
| Destructor. Will be called, automatically, if you're supporting just PHP5. If you're supporting PHP4, you'll need to call disconnect(). |
| _disconnect($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() param: string $data return: bool |
| _crc($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() param: string $data return: int |
| _string_shift(&$string, $index = 1) X-Ref |
| String Shift Inspired by array_shift param: string $string param: int $index return: string |
| _rsa_crypt($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() param: BigInteger $m param: array $key return: BigInteger |
| _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 param: array $message_log param: array $message_number_log return: string |
| _format_log_helper($matches) X-Ref |
| Helper function for _format_log For use with preg_replace_callback() param: array $matches return: string |
| getServerKeyPublicExponent($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. param: bool $raw_output return: string |
| getServerKeyPublicModulus($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. param: bool $raw_output return: string |
| getHostKeyPublicExponent($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. param: bool $raw_output return: string |
| getHostKeyPublicModulus($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. param: bool $raw_output return: string |
| getSupportedCiphers($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). param: bool $raw_output return: array |
| getSupportedAuthentications($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). param: bool $raw_output return: array |
| getServerIdentification() X-Ref |
| Return the server identification. return: string |
| _append_log($protocol_flags, $message) X-Ref |
| Logs data packets Makes sure that only the last 1MB worth of packets will be logged param: string $data |
