2011年4月1日 · 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 .

remote server with ssl ^ | (ssl-encrypted) socat | (not ssl-encrypted) v local port <-- run tcpdump here ^ | socat | v your terminal You then use a second socat connection to connect to the local port, where the first socat is listening. This is unencrypted.

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 emulate the serial device with a pty. To create a simple brigde with the following command: socat -d -d TCP:localhost:8888 pty,rawer

2015年6月20日 · socat TCP-LISTEN:22,fork,range=8.8.8.8/32 TCP:192.168.0.15:5900 Or you can add the tcpwrap=vnc_forward option and define global rules for that vnc_forward service as per hosts_access(5). That won't stop the connections from reaching socat, but socat will ignore them (with a warning) if they don't come from 8.8.8.8.

2020年9月30日 · Again, to workaround socat limitations, the reading socat has to use UDP-RECVFROM with fork and -u (for read-only, so its results are going to stdout, rather than being sent back to the responder) rather than the normally natural choice of UDP-RECV: that's to allow to fork one command per packet and transmit via environment variables the ...

2023年3月26日 · On the machine with the HTTP server you run socat to forward the virtual serial port to the SSH server (presumably one could use socat to forward an actual serial port as well): socat file:/dev/vport1p1,ignoreeof tcp:127.0.0.1:22 The ignoreeof option is critical in my case -- if you don't use it the socat just immediately disconnects. Depending ...

2018年6月10日 · Currently I am trying to setup a toy https server with socat I am doing the following: As described here: EXAMPLE FOR OPENSSL CONNECTION USING SOCAT cert() { openssl genrsa -out $1.key 2048 openssl req -new -key $1.key -x509 -days 3653 -out $1.crt cat $1.key $1.crt > $1.pem } $ cert server && cert client $ openssl dhparam -out dhparams.pem …

2023年5月4日 · socat TCP4-LISTEN:3389,fork TCP4:192.168.1.100:3389 socat UDP4-LISTEN:3389,fork UDP4:192.168.1.100:3389 It works fine when I start the service by hand in the shell, but I want to start it with systemd, and log into /var/log/socat-rdp.log. After some trials I can run the service like this:

2021年7月14日 · I feel there's a problem because socat doesn't go to background, but keeps running in foreground, so the service fails after a minute or so because of the timeout. Maybe I should wrap the socat command in a shell script to run it in the background like this:

2018年7月7日 · NOTE: This above tip can be heavily modified to debug anything that's going on between your socat/nc server and its clients. Making sense of socat arguments. I too find the configuration of socat exhausting at times. But like anything else, it's easiest to grasp if you break it up into smaller bits.
