Apr 1, 2011 · socat tcp-listen:8001,reuseaddr,fork tcp:localhost:8000 By default, socat will listen on TCP port 8001 on any IPv4 or IPv6 address (if supported) on the machine. You can restrict it to IPv4/6 by replacing tcp-listen with tcp4-listen or tcp6-listen , or to a specific local address by adding a ,bind=that-address .

Dec 6, 2021 · To try to realize this I ran the command socat TCP4-LISTEN:1337,reuseaddr,fork EXEC:./program. From this command, I wanted to be able to run nc 127.0.0.1 1337 and expected the program to: Recieve the message from the program; Be able to provide input; Lost connetion; However, when running the program using socat it goes like this. Give input

Feb 22, 2019 · I'm trying to create a bridge between TCP server and a client connected thorough a serial port using socat. I emulate my TCP server with the following command. socat tcp-listen:8888,reuseaddr - I emulate the serial device with a pty. To create a simple brigde with the following command: socat -d -d TCP:localhost:8888 pty,rawer

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

Jul 8, 2019 · I found socat is able to forward socket ports in general: socat tcp-l:8080,fork,reuseaddr tcp:127.0.0.1:12345 This forwards the "official" port 8080 to internal socket port 12345 successfully. BUT: my problem is that clients should be able to connect to port 8080 even if internal port 12345 is currently unavailable.

Sep 6, 2020 · In theory, you can set up a VM with a sufficiently rusty distro, say CentOS5, and build a static socat there, i.e. it will have all libraries baked in. You can then copy that socat binary and hopefully use it on a more modern machine. (configure --help for socat might have a switch to build statically.)

Jun 3, 2019 · How can query.bin now be sent to 8.8.8.8 again and the reply stored in a file called "reply.bin", using socat throughout? Eventually reply.bin will be sent back to the DNS client that initiated the query, eg dig above. But first, file query.bin will be manually inspected before the ok is given to pass it on to 8.8.8.8.

Mar 21, 2018 · On my host OS, I'm using socat like so: socat - /tmp/win-serial-com3,cr On the guest, I'm opening PuTTY, and set "implicit LF in every CR", and local echo is enabled. PuTTY opens COM3 on that guest Windows. With both running, return keys work fine, there is …
