2011年4月1日 · With socat on the server: 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. Same for the connecting socket you're …

2019年2月22日 · 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

2015年6月20日 · How can I tell to socat, that port 22 is only trusted from the remote IP address 8.8.8.8, and it should not accept connections from other IP addresses? This is on a Linux server.

2019年7月8日 · The problem with socat is that it does not seem to create a real socket server, but justs remapps the port, and just puts the port on LISTENING. I'm looking for a tool that tells the client "You connected successfully, please send me your input".

2018年3月21日 · OK, I found the solution, and it took quite a bit of trial and error: On the host side (Linux), this is how socat has to be invoked: stty -icanon && socat - /tmp/win-serial-com3,cr On the Guest side, PuTTY has to be invoked with "Implicit LF in every CR", and unset "Implicity CR in every LF", in the "Terminal" settings. It's still not ideal. When I press backspace on the host …

2019年6月3日 · 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.

2023年3月26日 · I'm looking to forward an http server (on Linux) over a single non-network bidirectional stream (specifically, a QEMU virtio-serial stream, but that doesn't really matter). Basically what I want is...

2015年7月26日 · The following socat command-line works as expected when entered at a shell prompt: # /usr/bin/socat UDP-RECV:4321 STDOUT It listens on UDP port 4321 and writes everything received to standard out...
