Secure connections with OpenSSHPublished: 11th Jan 2002, 13:45:20 | Permalink | Printable
A port a day keeps the good doctor away Updated Unix file portsdrobe.co.uk has recently learnt of a new step forward in networking for RISC OS in the form of an openssh port by Peter Naulls. Openssh will enable a user to securely connect and log into a remote machine. Although it is in testing at the moment, a version has been made available for any one interested and we're sure Peter will welcome your comments.
We want remote control
On your RISC OS desktop, you can open a taskwindow or press F12 and get a command prompt for that machine and using that command prompt, you can perform all sorts of tasks to control and configure your system. If you now take several computers and link them up into a network, you don't really want to have to sit at each computer in turn to perform similar command line tasks and configuration changes every time the need arise, especially if some of the machines are located on the other side of the office, country or world.
Step in a facility installed on the majority of networked machines that allows a user to remotely control a networked computer from another computer. By logging into a machine with a username and password, the user can control the machine as if she were sitting directly in front of it even though she might be several miles away. As an example, this editor keeps his email on a unix server so he can remotely log into the machine across the internet to read his mail from any computer, provided that computer has an internet connection. Various connection applications exist for RISC OS and all use the age old telnet protocol to send data to and from another computer. Telnet is unfortunately very insecure though as passwords and possibly sensitive data are sent across the network in an unencrypted form. The ssh protocol provides a secure connection by encrypting the data.

Further ports have appeared today on Peter's unix webpages. Various unix file utilities such as ls and rm have been ported by Alex Macfarlane Smith- see above links to Peter's webpages and see the change log for details.
