Client crashes when writing C5 48 69 12 B3 D5 C2 8A

[princeofpain]

Hi, I'm trying to write a proxy in Java (for educational purposes and personal use) and I was having some problems sending C5 48 69 12 B3 D5 C2 8A to the client, it would simply close every time I write to the socket using

sendC=soc.getOutputStream();
sendC.write(byte1);

What is the correct way to write packets to the socket? Any links or advice would be much appreciated.

The OutputStream#write method would be the correct way to write data to the socket, and your code looks like it's doing exactly that, but I can't tell for sure with just those two lines.
AFAIK, the client usually closes when you're sending invalid (improperly structured, unencrypted data to it).

Thanks, I got it working now.
