The Java Telnet Application

Hi to everybody!

I have got a problem to perform a SSH ver.2 connection to OpenSSH server. The server trace log show the error on: buffer_get_bignumber2: negative numbers not supported.

debug2: read_server_config: filename /etc/sshd_config

I believe that the problem is in the class SSHIO.java :

---------------------

pn = new SshPacket2(SSH2_MSG_KEXDH_INIT);
pn.putMpInt(BigInteger.valueOf(0xdeadbeef));
sendPacket2(pn);

------------------------

Someone Can help me, please?

Thanks a lot!
