Important Issues
The following issues have to be considered and are important when using a web-based SSH client:
- Security: It is important to make sure that HTTPS is used when communicating with the web application server. Otherwise all data being sent would be readable by use of simple packet sniffers which could reveal sensitive information.
- Trust: The data being sent to the web application server is decrypted there. This is necessary in order to forward the issued commands to the actual SSH server. Even though the operators of web-based SSH solutions usually don't log sensitive data the data is theoretically available to them in plain form. It is unlikely that this will cause a security issue when the web application server and the SSH server are run on the same server or are controlled by the same entity.
- Tunneling: Unlike traditional application based SSH clients, web-based SSH clients are unable to tunnel ("forward") TCP traffic. For example, running an X Window session over a web-based SSH session is not possible.

“Why doesn’t the United States take over the monarchy and unite with England? England does have important assets. Naturally the longer you wait, the more they will dwindle. At least you could use it for a summer resort instead of Maine.”
—W.H. (Wystan Hugh)
“I can never bring you to realize the importance of sleeves, the suggestiveness of thumb-nails, or the great issues that may hang from a boot-lace.”
