Lima<\/h2>\n\n\n\n
Lima<\/a>\u00a0launches Linux virtual machines with automatic file sharing and port forwarding (similar to WSL2).<\/p>\n\n\n\n

Port Fowarding(SSH)<\/h2>\n\n\n\n
eg. Forward traffic from 0.0.0.0:2222 to 127.0.0.1:60022<\/p>\n\n\n\n
1. Local Port Forwarding on the Same Machine<\/strong><\/p>\n\n\n\n
# socat\nbrew install socat\nsocat TCP-LISTEN:2222,bind=0.0.0.0,reuseaddr,fork TCP:127.0.0.1:60022<\/code><\/pre>\n\n\n\n
2. Remote Port Forwarding via SSH<\/strong><\/p>\n\n\n\n
Access a service on the remote server that\u2019s only bound to\u00a0127.0.0.1<\/code>\u00a0(not exposed to the internet).<\/p>\n\n\n\n
ssh -N -L 2222:127.0.0.1:60022 user@remote-server<\/code><\/pre>\n\n\n\n
    \n
  • -N<\/code><\/strong>: Tells SSH not to execute any remote commands (no shell session; just port forwarding).<\/li>\n\n\n\n
  • -L 2222:127.0.0.1:60022<\/code><\/strong>: Sets up\u00a0local port forwarding<\/strong>:\n
      \n
    • Local Port<\/strong>:\u00a02222<\/code>\u00a0(on your machine).<\/li>\n\n\n\n
    • Remote Target<\/strong>:\u00a0127.0.0.1:60022<\/code>\u00a0(a service running on the remote server\u2019s localhost, accessible only from the server itself).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
      When you connect to\u00a0localhost:2222<\/code>\u00a0on your machine, the traffic is encrypted and sent through the SSH tunnel to\u00a0127.0.0.1:60022<\/code>\u00a0on the remote server<\/strong>.<\/p>\n\n\n\n
        <\/ol>\n\n\n\n
        3. Firewall Rules (Linux\/macOS)<\/strong><\/p>\n\n\n\n
        For advanced setups, use firewall rules to forward traffic:<\/p>\n\n\n\n
        Linux (iptables)<\/strong>:<\/h4>\n\n\n\n
        sudo iptables -t nat -A PREROUTING -p tcp --dport 2222 -j DNAT --to-destination 127.0.0.1:60022\nsudo iptables -t nat -A OUTPUT -p tcp --dport 2222 -j DNAT --to-destination 127.0.0.1:60022<\/code><\/pre>\n\n\n\n
        macOS (pfctl)<\/strong>:<\/h4>\n\n\n\n
        Edit\u00a0\/etc\/pf.conf<\/code> and Apply the rules:<\/p>\n\n\n\n
          <\/ol>\n\n\n\n
          rdr pass on en0 proto tcp from any to any port 2222 -> 127.0.0.1 port 60022\n# Replace en0 with your network interface.\n\nsudo pfctl -f \/etc\/pf.conf\nsudo pfctl -e<\/code><\/pre>\n\n\n\n
