Hi,

at work I use some programs that get the license to work through the local network (for instance, mathematica). The problem is when I brign my laptop at home. Then I can only connect directly to a "gate" machine, but the machine that serves the license is inside this network and not directly reachable from outside.

I wonder how to use the program from home.

Of course, one solutin is;

1- ssh -X myuser@gatemachine
2- ssh -X myuser@anothermachine
3- mathematica &

but this is very slow as you can imagine

So I wonder if it would be possible in some way, doing some kind of tunneling or another way, to be able to tell the program at home that he can access the remote machine

thanks

hi

hacking your work network is not a good idea. I would talk to you IT person and ask if they can give you a software key on a thumb drive. this will let you use the program and keep you legal. Ive seen this done before and its not a big deal to do if your IT person knows how to do it. this is the simplest solution. there are always others.

for mathematica perhaps it works, but i use another programs which are on a server and depend on the hostid of that machine, ip, and some other details, so i can not get a copy

I wish it was so easy the solutions

thanks anyway

would it worth to use some kind of ssh tunneling for solving this problem ?

If you use a VPN tunnel, your laptop becomes a part of the local LAN in your office. It it just like you are plugged in at the office, it is almost fully transparent. I say almost, because the two networks behave as if they are separated by a router. Some protocols do not pass thru a router. There is also a bridging option with VPNs but that solution seems to be more complicated.

So the answer is YES, that would most likely work. But your IT dept has to install a VPN server for you. That can be done easy if they are using Linux. OpenVPN works perfectly for me.
