Re: [U2] Using SSL, with .Net to make a connection to Linux/Unix

Thank you everyone.  I'll let you know how things progress this week.

I don't know what '.NET TELNET tool' you refer to - but I wrote a customized terminal emulator in .NET for a
client that makes a connection Telnet/SSL connection to UniVerse on Solaris and tested fine on Linux. 

For the server configuration and details on setting up the secure telnet daemon take a look at my blog (you
can get to it from my website).

As far as the client is concerned, I can't give too much away as I don't own it - it was funded by a customer - but I
can probably share the following if you're tempted to roll your own!

1. for the low level connection I use a SecureTCPClient that wraps an SslStream - here are the salient pieces:

public delegate void SecureConnectionResultsCallback(object sender, SecureConnectionResults args);
    public delegate void ReceivedDataEvent( object sender, string data);
    public delegate void ReceiveErrorEvent( object sender );

    public class SecureTcpState
    {
           public SslStream stream;

Re: [U2] UniBasic SELECT

Keith:

Victory... 

The "F.ICC" argument was from an open statement...

	Open 'INV.CLASS.CODE'  to  F.ICC  else  null

When the command was changed from

	"SELECT F.ICC...

	To

	Execute "SELECT INV.CLASS.CODE..."

The pesky "SQL+" prompt went away.

Thanks very much indeed for the help.  I appreciate it.

Regards,

--Bill

Re: [U2] UniBasic SELECT

I think that SQL prompt only appears if the filename does not exist, or your
VOC pointer is off, etc.

In this case, thats what happened, because you were using the file open
variable instead of the actual filename perhaps?

Sounds like you figured it out :)

Re: [U2] Using SSL, with .Net to make a connection to Linux/Unix

Another thing to think about is that by default most Linux distro's heavily
restrict telnet.

My first question would be, are your Universe users using telnet or ssh?

If they are using ssh only, then I doubt a telnet system is even installed
on the Linux machine.

If they are using telnet, you might try checking the following files to see
if there are any security restrictions set:

One place might be /etc/hosts.allow AND /etc/hosts.deny
Here is a random blog entry on tcpwrappers (One package that can restrict
telnet access)
http://linuxhelp.blogspot.com/2005/10/using-tcp-wrappers-to-secure-linux.html

I think also many linux distro's use xinetd (instead of inetd) to run their
telnet daemon.

So, there may be some restrictions there also.
I think the config file is called:
xinetd.conf
http://www.xinetd.org/sample.shtml

>From a root prompt... do a:
find / -name xinetd.conf

Other than that, I've never done a .NET telnet connection, but, I have
worked with configuring telnet on Linux.

Re: [U2] Using SSL, with .Net to make a connection to Linux/Unix

Hi,
At this point, we are using an internal development server and our Admin does have SSL, and SSH, turned on and
it works with our terminal emulator.  Changing from SSH to SSL Telnet won't be a problem with our customers. 
The critical piece is that it must be an encrypted pipe.

Thanks for the thought.

Universe ships with its own secure telnet daemon for *nix running telnet over ssl (uvtelnetd). That's what
you need to configure.

Re: [U2] Using SSL, with .Net to make a connection to Linux/Unix

Actually, Universe ships a telnet for Window but not *nix.  The reason, according to U2 support, is that *nix
provides telnet and Windows does not.

[U2] /GC at SBXA 6.0.5.2501 not compiling

ALLOW.PDF is unassigned in the generated code.

Simple to fix, but annoying.

DMGC   GC.PD.R is not replacing \ALLOW.PDF\ with the result.

Anyone know where this is coming from?

Does not seem to be in DMSYSDEFN  GC.CONTROL

Not from PD.R <27,11>

Not from RD <37,3>

[U2] Why Pick Eclipse?

Someone on G+ had a post that summed up some of the angst I have
regarding Eclipse.  I think its the overbearing framework followed by
thin plugins.

http://nfarina.com/post/8239634061/ios-to-android

Eclipse has some strong points, but I think some of the apps (plugins)
I have tried had less functionality that free-standing competing apps.

Some examples:

Editor - pydev, bdt, eclim, {insert other editing widget for eclipse here} vs
    Any product by JetBrains, Emacs, VIM, Textmate, heck UltraEdit on win32.

For pure editing, all of these competitors have tons of features they
bring to the table.

The major thing BDT and others bring to the table are using u2 rpc and
svn.  Most of the editors I list also have a network layer, or just
using plain Samba on your dir file full of u2 src code.  There are
also dozens of ways to use git, svn, hg, etc.

Re: [U2] Using SSL, with .Net to make a connection to Linux/Unix

cd `cat /.uvhome`/bin
ls -ls uvtelnetd

But you only need this one is if you want to use their own secure telnet.
