Einen Tunnel (mit SSH) zu bauen, bedeutet, daß man eine Terminalverbindung auf einen anderen Rechner herstellt und über diese Verbindung (die verschlüselt ist) wir zusätzlich ein weiterer Port geleitet.
OBJECTIVE: the aim of the present study was to evaluate the efficacy of low level laser therapy (LLLT) in patients with rheumatoid arthritis (RA) with carpal tunnel syndrome (CTS). MATERIAL AND METHODS: a total of 19 patients with the diagnosis of CTS in 19 hands were included and randomly assigned to two treatment groups; LLLT (Group 1) (10 hands) with dosage 1.5 J/ per point and placebo laser therapy group (Group 2) (9 hands). A Galium-Aluminum-Arsenide diode laser device was used as a source of low power laser with a power output of 50 mW and wavelength of 780 nm.
Features
* On Demand
o Can load keys when ssh is launched.
o Can load keys when the Apple Keychain is unlocked.
* Security
o Can unload keys on sleep (or after a period of sleep).
o Can unload keys when the screenssaver kicks in.
o Can unload keys when the Apple Keychain is locked.
o Can lock the Apple Keychain when the screensaver kicks in.
o Can ask for confirmation when keys are accessed (useful for agent forwarding).
* Display
o Icon can be displayed in the statusbar, dock, or both.
* Integration
o Apple Keychain
+ Can store SSH key passphrases in the Apple Keychain.
+ Can lock/unlock the Apple Keychain from a menu item.
o Global Environment
+ Can add the necessary variables to the global environment, so you can use SSHKeychain with Project Builder, etc.
o SSH Tools
+ Works seamless with the commandline tools (adding keys from the commandline also updates the UI).
+ Can generate new keypairs from the UI.
* Networking
o Tunneling
+ Local ports can be forwarded over a ssh connection from the tunnel menu.
+ Tunnels can be launched when your keys are loaded.
+ The tunnel menu indicates the status of your tunnels.
+ Tunnels are automatically closed when the system goes to sleep.
+ Multiple ports can be forwarded over one ssh connection.
o Can handle agent requests through Agent Forwarding.
httptunnel creates a bidirectional virtual data connection tunnelled in HTTP requests. The HTTP requests can be sent via an HTTP proxy if so desired.
This can be useful for users behind restrictive firewalls. If WWW access is allowed through a HTTP proxy, it's possible to use httptunnel and, say, telnet or PPP to connect to a computer outside the firewall.
