Hi Team, I was able to extend commons-net Telnet API to support NTLM Authentication. I extended TelnetOptionHandler to create my own AuthTypeHandler for NTLM. For creating NTLM packets I used JCIFS API. The challenge NTLM message that I am recieving from the server is more than 256 bytes, but current commons-net API supports suboption message size upto 256 bytes only. There is a private integer array in TelnetInputStream named __suboption with size 256. If I increase the size, my authentication works perfect.
My question is, is there any specific reason why the array size is 256. Can it be increased? If I make it 512, my code works. Please suggest me because if I increase the size, I am able to telnet via a linux machine with NTLM Authentication by just extending the Telnet client provided in commons-net API. Otherwise, I will have to reinvent the wheel again ... write a Telnet client of my own. Thanks, Abhijeet Gaikwad
