Once you have a test packet that is not fragmented increase your packet size in small increments and retest until you find the largest possible packet that doesn´t fragment. When set to auto, SMB encryption is offered, but not enforced. stateful connection tracking - the ability to decide that a packet is valid (or not) using not only data from a packet itself but also from a history of a flaw. Type 0x11 looks like an SSL packet which has the first byte between 0x11-0x13(or some value around this). If the maximum TCP packet size is set too high, it exceeds the network's physical MTU and degrades performance by requiring that each packet be subdivided into smaller ones — a process is known as fragmentation. min is an integer which defines the beginning of the byte/packet range. will not examine code but will examine the effects of the code in order to understand what is happening at the data transmission level. To use the most common scenario let's use 1500 bytes, or (8*1500)=12,000 bits. conf file on my Linux Enterprise box to mandatory client and server packet signing.
