SSH - Secure Shell Access (V2)

3.17 SSH - Secure Shell Access (V2)
With firmware V2, the phone's operating system can be accessed via SSH for special trouble-
shooting tasks. Hereby, the administrator is enabled to use the built-in Linux commands. As
soon as SSH access has been enabled using the WBM, the system can be accessed by the
user "admin" for a specified timespan. When this timespan has expired, no connection is pos-
sible any more. The user "admin" has the following permissions:
• Log folder and files: read only
• User data folder and files: read/write access
• Opera deploy folders and files: read only
• Version folder: read/write access; version files: read only
It is not possible to logon as root via SSH.
>
When Enable access is enabled, and the parameters described underneath are specified,
SSH access is activated. By default, SSH access is disabled.
With the Session password parameter, a password for the "admin" user is created. This pass-
word is required. It will be valid for the timespan specified in the parameters described under-
neath.
Access minutes defines the timespan in minuts within which the SSH connection must be es-
tablished. After it has expired, a logon via SSH is not possible. The possible values are 1, 3, 5,
10, 15.
Session minutes defines the maximum length in minutes for an SSH connection. After it has
expired, the "admin" user is logged out. The possible values are 5, 10, 20, 30, 60.
