I am going to try to write simple BitTorrent client. Of course I read http://wiki.theory.org/BitTorrentSpecification. I began by analyzing communication between two clients. I have problem with meaning of two fields - bold font in the following hexadecimal dump.
First packet send by Deluge to rTorrent:

I am trying to commit a transaction on the Blockchain of the Hyperledger Fabric 2.2 after offline signing of the transaction from users private key.
After signing the transaction proposal,I send it to the endorsers for the endorsements and in response i get following endorsements from the endorser peers.

But, when i try to build,a required formatted proposal including the endorsements,to send it to the orderer so that orderer network, orders the transaction and sends it to committing peers for commitment on the Blockchain,but it gives following error
Failed to submit transaction: Error: Proposal has not been endorsed
code to build the proposal for the orderer
let commitment = new Commit('pki','mychannel')
let idx = client.newIdentityContext(user.user);
let commit = commitment.build(idx,{endorsement:ProposalResponse})
Followed these instructions https://hyperledger.github.io/fabric-sdk-node/release-2.2/Proposal.html#build
Any thoughts are appreciated
Im trying to view the data being written to an HTTP socket using strace
However, although I have given -e write=all, I still cannot see all the data being written
strace -o /tmp/capture.log -p <pid> -e trace=all -e write=all -e read=all -f -tt
..
29620 16:09:14.723120 write(1899, "POST /task/native.wsdl HTTP/1.1\r"..., 210) = 210
29620 16:09:14.723319 write(1899, "<soap:Envelope xmlns:soap=\"http:"..., 450) = 450
What is strange is that, it shows the complete data during some other writes to other sockets

Can somebody please explain. Is it possible to get data from all writes
The strace -e write=a,b flag shows write syscalls for file descriptors numbered from a to b, and -e write=all shows write syscalls to all file descriptors.
What you're looking for is -e abbrev=none; see the manpage:
-e abbrev=set
Abbreviate the output from printing each member of large structures.
The default is abbrev=all. The -v option has the effect of abbrev=none.

I want to remove only the hidden characters so that my actual file looks like :

Can someone please help me out in this?
Modifying with the actual file content above.
Are you using text files created under windows on Linux?. In that case you must install "tofrodos" package in your Linux distro, and then use "fromdos" tool to convert files from windows to linux format:
$ fromdos <windows-file-format.txt>
I'm trying to control my Panasonic TV via network. I had all my code (node) running from the laptop when I transferred it to the Raspberry. For some reason, it does not work from there. (A similar project controlling my Denon receiver works very well.)
By "Not Working", I mean, that the TV can be reached, but returns a 403 error. When TV is off, it's unreachable. So the Raspberry calls out to the TV.
I tried many different ways and eventually I'm working with a curl request. It works from everywhere, but not from the Raspberry:
curl 'http://192.168.178.142:55000/nrc/control_0' \
-H 'content-type: text/xml; charset="utf-8"' \
-H 'user-agent: net.thlabs.nodecontrol' \
-H 'soapaction: "urn:panasonic-com:service:p00NetworkControl:1#X_SendKey"' \
--data-binary '<?xml version="1.0" encoding="utf-8"?><s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><s:Body><u:X_SendKey xmlns:u="urn:panasonic-com:service:p00NetworkControl:1"><X_KeyEvent>NRC_MUTE-ONOFF</X_KeyEvent></u:X_SendKey></s:Body></s:Envelope>' \
--compressed
It does work from the Raspberry, if I proxy through any other device e.g. my laptop. However, it does not work, when I proxy from laptop through the Raspberry.
Trying for two days now, does anybody have a clue?
Edit: I reduced the curl even more: Without user-agent, content-type and compression this stilll works on any laptop (running windows, also tried WSL shell), but on my Raspberries (1+3, Rasbian and ArchLinux), I receive 403. When I additionally omit the soapaction I receive error 400 everywhere.

I have resolved the problem by resetting the factory parameters of my Panasonic TV. But I don't understand the root cause of the problem.
I'm developing a BitTorrent client and I'm having trouble getting answers to my piece requests.
To debug, I followed a conversation between uTorrent and transmission using Wireshark and tried to imitate same conversation in my client. But it still doesn't work.
Below is an example conversation happening between my client and transmission. (my client also using -TR--- prefixed peer id, this is only for testing purposes and I'll change this)
Indented messages are coming from transmission, others are messages my client send.
Note that this conversation is not exactly same as how uTorrent and transmission would talk, because my client does not support fast extension yet. (BEP 6)
(Output is taken from Wireshark, lines starting with -- are my comments)

Any ideas what am I doing wrong?
Thanks.
EDIT: I updated my client to send unchoke just after sending interested, but I'm still having same problem...
The problem was that I was requesting a piece bigger than the total size of the torrent.
The torrent I was using has 2 files, in total of 12KB. However the piece size of the torrent is 16KB and I was requesting 16KB piece even though the torrent file has only one piece and it's 12 KB in total.
After requesting 12KB instead of 16KB, the problem was solved.
