Dec 26, 2021 · **** This is for learning purpose. I just like to deep dive into sockets, tcp, packets, etc. For doing tests and learning, I began to "play" with socat CONTEXT (tests) : 1- Bind a port to a

Mar 5, 2022 · What is the format to make all these forwards inside a single socat.service file? If there is no way to do that, can I write multiple socat statements inside a bash file and put that inside ExecStart?

Looks to me like your core is solid -- this should be reliable, and should quit once the file has been completely sent. If out.txt already exists, though, then this setup might behave unexpectely. If out.txt is longer than test.txt, the last part of out.txt will remain, since socat is overwriting the file byte by byte instead of making sure the file is empty. There are a few ways to fix this ...

I'm running some performance testing, and I'm trying to send the same file repeatedly to a socket. If I do something like: $ socat -b1048576 -u OPEN:/dev/zero TCP4-LISTEN:9899,reuseaddr,fork $ s...

Nov 23, 2010 · netcat is simple but not all versions close connection reliably. Here is thread about using socat: socat reliable file transfer over TCP To sum it up: Proposed: Server sending file: server$ socat -u FILE:test.dat TCP-LISTEN:9876,reuseaddr client$ socat -u TCP:127.0.0.1:9876 OPEN:out.dat,creat Server receiving file:

May 5, 2023 · Solution with Socat: What happens in your attempt is: After the first successful transfers the shell writes the file contents and terminates. Socat transfers the data to the server (and sends EOF using TCP halfclose). The server receives the data (and EOF), and sends the processing message.

I quite like tcpdump for recording network connections. You actually can use it for what you want to achieve. Instead of using the READLINE endpoint in your socat connection, make it listen to some port. remote server with ssl ^ | (ssl-encrypted) socat | (not ssl-encrypted) v local port <-- run tcpdump here ^ | socat | v your terminal You then use a …

Nov 26, 2019 · I already transferred 10% of the file, but I learned there will be a scheduled outage in some hours. How can I ask netcat or socat or curl to serve the FILE:database.raw at the offset it was interrupted? or

Dec 17, 2020 · socat file:`tty`,raw,echo=0 tcp:127.0.0.1:1337 I can also send a file instead of interactive input: socat file:/tmp/myfile'!!'file:`tty`,raw,echo=0 tcp:127.0.0.1:1337 How do I combine the two, i.e. first send the contents of /tmp/myfile, and then send-receive on the current TTY indefinitely? Is it possible to do it with socat? If not, how do I ...

Sep 6, 2023 · Let's say one is listening on a tcp port for an incoming connection using socat like this: $ socat file:`tty`,echo=1 "TCP-L:8080" Is is possible to run a command (just once) when connection is received? It can be any command, though I intend to …
