SSH reverse tunnel

# ssh -nNT -R 10.36.1.6:14344:10.36.1.5:80 10.36.1.6 The "-n" option prevents reading from STDIN. Redirection from /dev/null to STDIN. "-N" tells ssh that the tunnel is not for executing remote commands. "-T" tells ssh not to allocate a pseudo-tty on the remote system. "-T" disables pseudo-tty allocation. Rough diagram: 10.36.1.5:80 <--- 10.36.1.6:14344 To avoid timeout: In /etc/ssh/sshd_config on the server: TCPKeepAlive yes ClientAliveInterval 30 ClientAliveCountMax 99999 To enable binding address in ssh -R : GatewayPorts yes Man page docu for -R switch: -R [bind_address:]port:host:hostport Specifies that the given port on the remote (server) host is to be forwarded to the given host and port on the local side. This works by allocating a socket to listen to port on the remote side, and whenever a connection is made to this port, the connection is forwarded over the secure channel, and a connection is made to host port hostport from the

Motorola MOTOKRZR K3 and Smart 3G

Word of Warning: I am a Linux user and very keen in buying a Motorola Razr (specifically v3xx) because it is known to work in Linux. But for some stupid reason I bought a newer model and it is NOT based on this chipset anymore: # lsusb Bus 001 Device 002: ID 22b8:6402 Motorola PCS # dmesg [30549.844000] cdc_acm 1-1:1.0: ttyACM0: USB ACM device [30549.844000] usbcore: registered new interface driver cdc_acm [30549.844000] drivers/usb/class/cdc-acm.c: v0.25:USB Abstract Control Model driver for USB modems and ISDN adapters I have not tried yet making it work in Linux but might write a dev driver for this if time permits.
