2 bytes for the type, 2 bytes for the length, followed by the value. The value of password is a variable length value that is to be used as a shared secret.

There is a bug to change the default mtu of stun interface from 1500 to 2104.

However, changing mtu size on a stun interface.

It is always present in a shared secret response, along with the username. I am sending 4 bytes of data over udp upon request from another program. Since all stun attributes are padded to a multiple of 4 bytes, the last 2 bits of this field are always zero. Sometimes the frame's protocol is identified as stun in wireshark, but i have no clue why.

When an ipv4 packet must be fragmented, the data must be divided on a multiple of eight octets. I think that the bug id is cscdz28817. Is there any way to remove the enclosing 4bytes from the turn header (without export manual search&replace) to decode the package as rtp? That is because the fragment offset field is three bits smaller than the total.

Since stun aligns attributes on 32 bit boundaries, attributes whose content is not a multiple of 4 bytes are padded with 1, 2 or 3 bytes of padding so that its value contains a.

The goal should be to see. I am using the mainline version of. Failed to create stun message from packet:
