I also found a problem with Packet.ReadLenInteger.

It was using the values for shortLen, intLen and longLen to read the length
of the blob that is sent across. As Packet.LongInts had been set to try,
this meant that it was using 4 bytes to read the length when it should have
been using 3. I changed ReadLenInteger to the following

		public long ReadLenInteger()
		{
			byte c  = (byte)ReadByte();

			switch(c) 
			{
				case 251 : return NULL_LEN; 
				case 252 : return ReadInteger(2);
				case 253 : return ReadInteger(3);
				case 254 : return ReadInteger(8);
				default  : return c;
			}
		}

This is working for me, so hopefully this was the correct thing to do.

Regards

Nick

Nick

This is a valid change.  In fact, we have already made that change in our
source repository so this bug will be fixed in the forthcoming beta release.
