How can I set up routes on my Droid

I have CM7 and OpenVPN installed on my Droid. I can establish a VPN tunnel and get an IP address from my office. In a terminal emulator, I can do

Code:

ssh user@10.x.x.x

and log into my server. What I want to be able to do is

Code:

ssh user@host

and also to click through links in e-mail notifications from our Trac system (e.g.,

Code:

https://trac.example.com/trac/ticket/1234

). I tried editing /etc/hosts but it seems to be on a read-only file system. How can I make my Droid know my hosts by name?
