Hi,
You may know I'm working towards sharing an unlimited sify account on a school network. Here are some observations I'd like to share with all of you
- I'm running a NAT router, that is a router which hides all yoru LAN hosts t from the outside world. It's a good idea combined with a firewall.
Now, the way the sify client is made, when you login from any system on the network, sify actualy logs in your router. This has the very interesting side effect that you can use the connection from _any_ computer on your lan using the router as default gateway.
What I wonder is how it will work if there are two packets used simultaneously. I think it won't work in the same way you can only start one instance of the sify client under windows. Has anyone tried this ?
I'd like to know if this is authorized from sify. I haven't seen any contract forbidding to share a connection and since the speed-cap is there anyway, it doesn't change anything to them. But I wouldn't like to encourage you to any illegal action.
- firewall : I strongly recomden using a firewall when using a sify connection because you're on a LAN with an unknown number of others. It's qutie amazing the kind of logs I get ! ranging for regular windows shared drive scans to brute-force ftp connection attempts p@$$ing through long portscans.
- I have unconfirmed reports that one can use the internet when someone else on the WAN [at least before it goes to an SU] is connected. There was a time when our account was depleted for a couple of days, and we could still surf every once in a while - the automatic ICQ login was what attracted my attention. This is independent from the whole NAT router buisness explained above.
Can anyone confirm this ???
Be carefull though, I'm no lawyer, but I think it would be pretty illegal to use your neighbour's connection ! So don't blame me for ending up in jail if you get caught.
- To all of you seeking security, I'd recoment a german single-floppy distribution, fli4l - http://www.fli4l.de. The documentation exists in german and english. Very little linux knowledge required to set it up. And it can be a neat way to recycle that ol' 486.
That's it for now.
