tunnel

Is it possible to get an bidirectional IP-tunnel over ttyS0-like serial (modem) devices with the socat utility? I tried to use TUN option but still can't get the result. Any suggestions are welcome :) Update: PC1: socat /dev/ttyUSB0,raw,echo=0,b57600,clocal TUN:192.168.1.1/24,up PC2: socat /dev/ttyUSB0,raw,echo=0,b57600,clocal TUN:192.168.1.2/24,up After that, I have seen tun0 interfaces with proper addresses on both ends but I can't ping one from other. Instead of that, when I send data with ping -c 1 192.168.1.1 remote socat process exits and it's tun0 device destroyed. Any suggestions?..

I want to create an SSH Tunnel in Java. I noticed quite a few Java SSH libraries on another post . Before I dig into each option, maybe someone can give me some code snippets of how they did it or at least tell me which client library would work best. I only need tunneling. I won't need stuff like file transfers, terminal emulation, etc. Is there a simple few lines of code that can forward a port on the server to work on my client's localhost adapter? Ideally both client and server would be in Java, but I'll settle for just client for now. Well, as pointed out in the other question, JSch is

I am faced with a curious behaviour of java6/8. I try to tunnel through a proxy which needs basic user authentication. Doing this by the standard java Authenticator. If I try to access a https url as the first url, an exception is thrown: java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required" But if I access a http URL first and then the https URL, the https access works fine. Given that code: import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.net

I'd like to use RazorSQL to connect to my database which is running on a remote server. I create a SSH tunnel on my localhost with the following command: ssh -L 1111:remote.server.com:5432 myuser@remote.server.com I configure my connection via RazorSQL's GUI, specifying localhost as the host and 1111 as the port. When I click on "Connect", the following error message appears: ERROR: An error occurred while trying to make a connection to the database: JDBC URL: jdbc:postgresql://localhost:1111/myuser FATAL: no pg_hba.conf entry for host "aaa.bbb.ccc.ddd", user "myuser", database "mydatabase",
