Error Undefined Constant

[MadTomT]

Hi,
I'm using an old version of phpseclib and it works fine for my requirements. However after an OS upgrade I've now started to get the following error:

"PHP Fatal error: Uncaught Error: Undefined constant "NET_SSH2_DISCONNECT_BY_APPLICATION""

Looking at old posts I can see this has been resolved, but my issue is I can't user composor to install the updated application.

I've read v2.0 will still allow manual installation, so I've copies the files to my server but then I get "PHP Fatal error: Uncaught Error: Class "Net_SSH2" not found"

The code I'm using to make the connection is $ssh = new Net_SSH2( $ipaddress );
Looking at Net/SSH/SSH2.php I can see the name has now changed to SSH2, so I changed my connection command to
$ssh = new SSH2( $ipaddress ); but that gives error "PHP Fatal error: Uncaught Error: Class "SSH2" not found"

This is the example I'm currently using.

include('/Net/SSH2.php');

$ssh = new SSH2( $ipaddress );
if ( !$ssh->login( $user, $password ) ) {
	exit('Login Failed<br/>');
}

Could some one help me get this working.
Thanks

Apologies for the delay - I was out camping this weekend.

Looking at Net/SSH/SSH2.php I can see the name has now changed to SSH2, so I changed my connection command to
$ssh = new SSH2( $ipaddress ); but that gives error "PHP Fatal error: Uncaught Error: Class "SSH2" not found"

Sounds like you're trying to use the latest code in the master branch when you should be using the latest code in the 2.0 branch:

Thanks, I am using 2.0.41 and that is what's showing the error.
Any idea how I can resolve this ?

How did you install phpseclib? phpseclib 2.0 requires the use of an auto loader. Like you shouldn't be needing to do include() on any phpseclib files. I mean, you could do so but, most likely, you'd have to painstakingly load all the dependencies as well (eg Math/BigInteger.php, Crypt/Rijndael.php, Crypt/Base.php, etc). And even if you were going to go that route, most likely, the Net directory is not installed in the root directory as include('/Net/SSH2.php'); would imply but, rather, is installed in the current working directory. ie. if you were going to include a file you'd prob be better off doing include('./Net/SSH2.php');
