Thanks Carlos, Xen and James for the explenations! (I'm always a bit shy to answer in this thread, I hope it does not annoy too much to purely open-suse-related people. But for me it is very interesting and I think I already learned a little more...) Am 20.09.2015 um 01:41 schrieb Carlos E. R.:
I forgot about phishing and social engineering: say that somebody sends to you an email asking you to read some report on a photographer meeting at La Hague, or offering a contract. You would be intrigued and have a look. Well, that's a possible dangerous situation.
Yes, they try a lot. Apart from stupid ones (cancelling a credit card I don't have, warning of a paypal block 15 times a day, using such bad translations that it already gets funny, sender addresses or links that point to other addresses than shown in the text...) some might be made intelligent enough to trigger me. Well, it doesn't need so much :-) I do open image files from unknown senders with quickshow and I some pdf's with okular. Unknown websites coming up with flash contents (blocked by my browser settings) are not viewed. But yes, they triggered my mother into opening an attachment (a hidden .exe) writing her that her bank account had been charged a high sum. She clicked and clicked the .exe, and as nothing happened (she's on linux, too) she desperately called me...
If they send you an email with a text that seems realistic and intriguing, specially if they already know about you, it is possible that you get hooked. It is dangerous, more than virii.
It's possible. I try to keep my brain up and running... ...
I have the ssh server "on". I need it to let my laptop connect, for rsync and the like,
Ok, but you use it for connecting inside home; not to connect from a coffee shop, right?
No. Just used to surf a bit the web, but since a company sold an application to many cafés that offer free WiFi when you login via facebook, not even that. I heard a conversation of an agent of this company and the statistics about those who connect in the café she offered to the owner let my hair stood on end. No, I only connect my laptop to my PC at home.
I would really like to know how I can manage that only MY laptop can ssh to the PC (and reverse). Due to DHCP, IP's change, so filtering by IP wouldn't help...
Well... If you configure for static addresses instead, you can then filter in the firewall to allow those addresses.
Some home routers can be configured to assign a certain IP to a certain machine, via DHCP. So the computer is still on automatic network configuration, but it always gets the same address.
On http://adslzone.net/ you can find information about the routers typically used in Spain, with howtos for doing typical things.
The page is open. I read in little mouthfuls...
What I "fear" most, is that one of my guests (to whom I gave the WiFi password) can follow my web-actions or even get into my PC....
Ahhh, it's all so complicated :-)
Well, getting into your PC is not trivial.
Following your web actions is easier, /if/ your router publishes all network traffic of everybody on the wireless interface, which they typically don't. If you are connected by cable, it is easier to "sniff" (that's the name of the action).
Why is that easier? I thought the contrary. My main PC is connected by cable... Should I better connect it per WiFi? (I have an old WiFi-card laying around somewhere...) Enjoy a sunny sunday!
