php - Connecting via SSH with RSA using PHPSECLIB -


i learning how use 'phpseclib' library.

i have managed connect via ssh using username/password combo.

i want connect using private key, can't seem able it. let me explain how have gone , can point me errors of way.

<?php  use phpseclib\net\ssh2; use phpseclib\crypt\rsa;  include('vendor/autoload.php');  define('net_ssh2_logging', ssh2::log_complex);  $ssh = new ssh2('myip'); $rsa = new rsa();  $rsa->setpublickeyformat(rsa::public_format_openssh);  extract($rsa->createkey(2048));  file_put_contents('privatekey', $privatekey);  if($rsa->loadkey(file_get_contents('privatekey'))) {     echo('key loaded'); } else {     throw new exception('key not loaded'); }   if($ssh->login('chris', $rsa)) {     echo('connected'); } else {     echo $ssh->getlasterror();     throw new exception('not connected'); }

as can see, set public key format 'openssh' , create key. using values created createkey method put key in file called 'privatekey' (no extension, unsure if needed it's text). normal, loading key , using value in login.

i've used official docs (which aren't great) , google'd around , i've not had luck either.

the output of getlasterror is:

ssh_msg_userauth_failure: publickey,password

thanks in advance assistance.

you can create key pairs day on client side unless public part of key pair generated in /home/user/.ssh/authorized_keys file it's not going matter. , if you're creating keys , trying connect them in same script... it's unlikely they're going in file.

in particular case should load private key corresponding public key in /home/user/.ssh/authorized_keys file. load $rsa->loadkey(...) , /then/ try use rsa object in ssh's login method.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
