network

Wired this time, here is a command to check if there is physical connection on the ethernet line.

ethtool enp0s25

brother scanner

To detect the scanner over the network first figure out the ip address, which might mean going into the menu of the printer itself. Mostly it has been .29 .

After downloading the help tool from the brother site : visit

Of course my model was not listed but i chose the correct one as it seems, to be exact this was the download link: visit

And the debian package it results in is called : brscan4-0.4.2-1.amd64.deb

apt-get install xsane
dpkg -i brscan4-0.4.2-1.amd64.deb
brsaneconfig4 -a name=brother model=MFC-J4620DW ip=192.168.2.29
# as normal user : 
xsane 

The name is the friendly name and could be used for other commands, like delete.After install just start xsane as a user or from the app menu.

wireshark

Here is a detailed dump from a http REST GET request in wireshark. The reply is worked out in detail below. The initiating request looks like this:

GET

The request itself is fired from PostMan :

GET http://localhost:3000/api/orders

In wireshark this show up as :

Note that i added some x-www-form-urlencoded parameters in PostMan so these show up in the end as well. The final plain html request that gets sent is from the GET and it's mainly plain text separated by 0D0A terminators. 0x0D is CR (carriage return) or r and 0x0A is LF (linefeed) or n so you could also call it CRLF or rn.

REPLY

The total dump is 2088 bytes. Here is a breakdown to try to understand this a little bit. The window for this packet shows :

• Frame 12: 2088 bytes on wire (16704 bits), 2088 bytes captured (16704 bits) on interface 0
• Ethernet II, Src: 00:00:00_00:00:00 (00:00:00:00:00:00), Dst: 00:00:00_00:00:00 (00:00:00:00:00:00)
• Internet Protocol Version 6, Src: ::1, Dst: ::1
• Transmission Control Protocol, Src Port: 3000, Dst Port: 33770, Seq: 1, Ack: 325, Len: 2002
• Hypertext Transfer Protocol
• JavaScript Object Notation: application/json

These are the various protocols recognized by wireshark :

Frame 12

12 is just the wireshark sequence number, it stands for the complete frame of 2088 bytes. This really means raw bytes.

Ethernet II

The 2088 bytes get encapsulated like this :

visit

This is the layer 2 ethernet frame. If you select that line it highlights 14 bytes.

00 00 00 00 00 00 00 00 00 00 00 00 86 dd

This is only the MAC header, the ethernet II frame still contains the complete 2088 bytes.

The first 6 octets are the source address and the second the destination. Note that these are ethernet level MAC addresses. Both source and destination are the loopback interface, and that does not need an address. ip a will also show 0 for lo :

ip a 

..
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
..

Then the last two remaining are 86 dd which stand for the ethernet type.

Wireshark tells us 0x86dd is ipv6 !! The last 4 bytes now are a checksum for the frame content, so everything between is a 2082 byte data payload.

Everything in between is an IPv6 internet frame.

internet frame

Have cut out the bytes not belonging to the header :

0000                                             60 0e                 `.
0010   17 cf 07 f2 06 40 00 00 00 00 00 00 00 00 00 00   .Ï.ò.@..........
0020   00 00 00 00 00 01 00 00 00 00 00 00 00 00 00 00   ................
0030   00 00 00 00 00 01                                 .......         

This is the ipv6 header, stating :

• 0x6 : the version (NOTE : only 4 bits !!) : 6
• 0x00 : traffic class (6+2 bits)
• 0xe17cf : flow label (20 bits) : to do with routers and switches

These settings go just about too low for me to want to know. More important are

• 0x07f2 : (16 bits) which is the payload length : 2034
• 0x60 : next header : tcp (6)
• 0x40 : hop limit : 64
• source : 128 bits (::1) still localhost values
• destination : 128 bits (::1) still localhost values

The 2034 byte payload then contains the TCP protocol frame :

tcp protocol

0030                     0b b8 83 ea a5 5c 3a f2 65 bf   
0040   10 7a 80 18 01 5e 07 fa 00 00 01 01 08 0a 08 76  
0050   dc f4 08 76 dc f2                               

This takes 32 bytes, and the format can be seen here : visit

• 0x0bb8 : source port , 16 bits : 3000. Note that this is the answer/reply, so it's the server's source port which is the express implementation in localhost:34000
• 0x83ea : destination port : 16 bits : 33770. This the port that the client opened to communicate with the server, so it's arbitrary and happens to be 33770.
• 0xa55c3af2 : sequence number.
• 0x65bf107a : acknowledgment number
• 0x8 : data offset or better header length in 32-bits words, so 8 is 32 bytes !
• 0x01 : various flags, like SYN,ACK, FIN
• 0x015e : window size : 350 has to do with scaling and flow control
• 0x0f7a : checksum
• 0x0000 : urgent pointer.
• 0x0101080a0876dcf40876dcf2 : options
• padding : up to 32 bits bounds, not needed in this example

The next byte after that is the payload of 2002 bytes of pure http text.

http protocol

After this we get a plaintext protocol, it starts at byte 0055 and is what the browser gets starting with HTTP/1.1... The rest is not show, but it contains the rest of the data.

The buildup is like this , headers separated by CRLF.

HTTP/1.1 200 OKrn
X-Powered-By: Expressrn
Access-Control-Allow-Origin: *rn
.. etc

In Postman these can be viewed in the headers tab :

X-Powered-By →Express
Access-Control-Allow-Origin →*
Content-Type →application/json; charset=utf-8
Content-Length →1755
ETag →W/"6db-QSJxJ9up7TPBH559w1EqUgBnMbM"
Date →Wed, 07 Aug 2019 09:34:51 GMT
Connection →keep-alive

Note also that the header section is closed with an extra rn :

0140   65 65 70 2d 61 6c 69 76 65 0d 0a 0d 0a 7b 22 73   eep-alive....{"s
# or ...
Connection →keep-alivern
rn
{"status ....

After the headers comes the reply data, and in wireshark you even get the json part as a separate section but it is part of the http request.

complete frame

Here is the complete byte sequence of the reply.
