SSH

In addition to an unencrypted and potentially compromisable Telnet connection
you can also connect to your gateway via an SSH connection. This is encrypted
and allows you to securely make use of all remote maintenance options offered
by bintec products.
In order to connect to your gateway via SSH, the following requirements must
be met:
■
You need to have encryption keys created by your gateway and stored in
the Flash ROM.
■
You need an SSH client installed on your PC.
Encryption Keys
ToDo First of all you must make sure that the encryption keys required for a SSH con-
nection have been created on your gateway:
1. Login to your gateway using one of the already available connection meth-
ods (e.g. Telnet - for logging in,
2. At the the command prompt, type update -i. You now have access to the
Flash management shell.
3. Call a listing of all files stored on the gateway: ls -al.
If you see something like this, the keys have been created and you can login to
your gateway via SSH:
Flash-Sh > ls -al

For each of the so called algorithms the gateway creates a key pair, i.e. two files
must have been stored in the Flash for each algorithm (see screenshot above).
