[Telnetd-devel] Problem using Telnet daemon

[Singhal, A. (Ankit) <asi...@lu...>]

Hi Dieter
 
I am a new user of your TelnetD software.I want to embed this to my
software, but I am facing some problems in regard to that.
The problem is being faced while implementing the Shell Class.
 
I want to implement my own shell class (MyShell.java).In this shell class I
am connecting to some other Software component.
So while implementing that class I have to use available() as a call instead
of read() because i don'nt want to block my program on that.
 
The problem i am facing is that when the user closes the Telnet client
abrubtly , my Telnet Daemon program doesn't end the conectio thread while if
i am using your DummyShell then this is taken care by you.
I further investigated the code , and i found that you have use EOF
Exception to check this condition. So I put my available() code in try block
and used the same EOF Exception condition to catch it. But it is not coming
in catch block when I forcefully close the telnet client .
 
Can you please let me know  at waht pint am doing the error.
Please find below the snippet of code what i am writing.
 
try{
while(iss.available()>0)    {
     System.out.println("Inside avilable");
     i=iss.read();
     if (i == -1 || i == -2)
     {
      TelnetD.debuglog.write("Input(Code):" + i);
      flag=false;
      break;
     }
 
     if(channel.isEOF())
      {
       flag=false;
       System.out.println("Disconnected");
       break;
                      }
   fout.write(i); //Key Stroke Logging
 
    }
}catch(EOFException)
{
if (m_Connection.isActive()) {
        System.out.println("Connection broken forcefully");
        TelnetD.debuglog.write("Registering broken connection " +
m_Connection.toString() + " active=" + m_Connection.isActive());
 
m_ConnectionData.getManager().registerBrokenConnection(m_Connection);
}
    
Thanks and Regards
