Remote login with php ?!

Hi guys,
I need your help!!
We got a network of several unix pcs.
I need to build a website, that gets username and password in a form, logs on to a remote unix computer and executes programs, does directory listings and so on.
Sounds quite easy, but how do I log on to that remote computer?! rlogin and all these commands can't be used with username and password together, they always prompt for the password. This is not really what I need.
Are there any PHP functions I could use?
Thanks!
Stefanie

Thanks, this function is just what I needed.
Do you have an example for this with a unix connection? I tried both, the hostname and the ip, but it doesn't establish a connection.

this. =)

Japp, that would be it ...
now it does establish the connection, when i use the telnet or rlogin port. but i can't send any commands. i believe i'm in direct connection with the port when i connect with port 513 (rlogin). but how do i open a terminat or how do i get a prompt?!

if anyone cares: i found a wonderful telnet class that does (nearly exaclty) what i need.
Code: Select all
<?
error_reporting(-1);
class Telnet {
/* (c) thies@thieso.net */
var $sock = NULL;
function telnet($host,$port) {
$this->sock = fsockopen($host,$port);
socket_set_timeout($this->sock,2,0);
}
function close() {
if ($this->sock)
fclose($this->sock);
$this->sock = NULL;
}
function write($buffer) {
$buffer = str_replace(chr(255),chr(255).chr(255),$buffer);
fwrite($this->sock,$buffer);
}
function getc() {
return fgetc($this->sock);
}
function read_till($what) {
$buf = '';
while (1) {
$IAC = chr(255);
$DONT = chr(254);
$DO = chr(253);
$WONT = chr(252);
$WILL = chr(251);
$theNULL = chr(0);
$c = $this->getc();
if ($c === false)
return $buf;
if ($c == $theNULL) {
continue;
}
if ($c == "\021") {
continue;
}
if ($c != $IAC) {
$buf .= $c;
if ($what == (substr($buf,strlen($buf)-strlen($what)))) {
return $buf;
} else {
continue;
}
}
$c = $this->getc();
if ($c == $IAC) {
$buf .= $c;
} else if (($c == $DO) || ($c == $DONT)) {
$opt = $this->getc();
// echo "we wont ".ord($opt)."\n";
fwrite($this->sock,$IAC.$WONT.$opt);
} elseif (($c == $WILL) || ($c == $WONT)) {
$opt = $this->getc();
// echo "we dont ".ord($opt)."\n";
fwrite($this->sock,$IAC.$DONT.$opt);
} else {
// echo "where are we? c=".ord($c)."\n";
}
}
}
}
$tn = new telnet("123.123.123.123",23);
echo $tn->read_till("ogin: ");
$tn->write("username\r\n");
echo $tn->read_till("word: ");
$tn->write("password\r\n");
echo $tn->read_till(":> ");
$tn->write("ps\r\n");
echo $tn->read_till(":> ");
echo $tn->close();
