UNIX for Dummies Questions & Answers

If I'm at a wireless cafe running SuSE and I want to read my mail but the wireless cafe blocks port 25 for smtp but I have a VPN connection to my home machine, how do I use the "route" command.

If I'm at home on my windows machine and have a VPN connection to another network, can I use the cygwin route command to access a web site under a different IP?

I notice that when I try to browse my own web site (that I am serving), I cannot specify my WAN address. I have to specify my LAN address. Of course, putting LAN addresses in my links is not very effective for anyone outside my LAN!

But if I had a VPN to another network and could come in from that network, that would solve my problem!

Thanks,

The route command has nothing to do with the situation. Route commands manipulates the routing table as you have two or more interfaces connected to different networks, or specific routes are accessible by other gateways rather than the default. Then you use route command to introduce these routes as your computer normally uses standard IP forwarding routing and doesn't know how to obtain the alternative routes, since it normally doesn't use routing protocols.
In your case, as you sit in a cafe, it has one default router and no other means to communicate with Internet. VPN implies tunneling connection trough some encryption, you may suspect that port 22 is blocked by the router but port 25 has nothing to do with it (even if it is blocked as you connect trough VPN) if your computer connects to VPN because it does not connect to the mailbox explicitly. It is also possibility that it is blocked by router one level above the router in cafe as it may be part of their internal policy. "UNIX Essential and Core" DVD explains this stuff.

I did a google search for "UNIX Essential and Core" and could not find it. Is it something I can buy somewhere? Is it a online tutorial or book?

Is what I want to do impossible, or is there just no software to do it?

Thanks,

I performed "UNIX Essentials and Core" search on Google and it came back with zillion links to it. It is UNIX course on DVD, read the description, here the links ...
