Shell Programming and Scripting

i have a sun solaris workstation that want to be able to access when i'm not home.

is there way to do this? like say i have the workstation turned on at the house but say i'm in a hotel several miles away, i want to be able to access this workstation using the internet on my laptop

You can use secure shell to do that.

ok. how does that work? i mean, i know how ssh works. i use it all to the time
but how am i going to be able to ssh into a workstation i have sitting at home?

I just forward port 22 thru my firewall at home to port 22 on the machine I want to admin and use dyndns to allow me to ssh to radar@host.dyndns.com due to my dynamic IP.

only if this can be simplified as i dont get it.

If your workstation is on a private network at home and your router has a dynamic IP assigned by the internet provider, you can use dyndns to register a domain name to associate with a changing IP. A client can run in some firewalls you buy for home use that will update dyndns with the new IP if it changes. If you forward port 22 to the solaris workstation IP address, the firewall will see a request for port 22 on its interface and forward it to the workstation.

Code:

ssh radar@host.dyndns.com ---> port 22 ---> myFirewall(24.xx.xx.xx) ==> port 22 ==> workstation(192.168.1.3)

so basically this would be:

ssh radar@host.dyndns.com port 22 24.xx.xx.xx 192.168.1.3
