Hi!

I try to install "Synergy" through my Synaptic Package Manager and its listed but I get a message "Can't be authenticated".

This is a programme for sharing mouse, keyboard and clipboard over the network, so you can move over screens like they are joined together. This the website " http://synergy-foss.org "

I am a bit concern about the message and security due to if you gain control of the interface could some serious damage made, right?

You still need the sudo password but what about you doc files?? they could get wipe out/or copy, right?

Thanks for your input here!

I don't really understand your association between the way a package is installed and what the package is. Regardless of how you get it installed, it is a program that exposes a certain level of network connectivity. Same for sudo.. no idea why that's being mentioned here at all.

You trust sudo as a mechanism or you don't, how does synergy relate to this?. Synergy doesn't expose your desktop, it shares mouse devices, it's good. I use it a lot.

So what where you actually worried about? Still not clear.

I guess you didnt see my point at all!

let start with the message "Can't be authenticated", why may I getting this message? Thanks

That is that the package manufacturers signature isn't installed on your system. The packager isn't going to be the synergy project itself, but a third party makign them for ubuntu. I don't know if that's Ubuntu themselves or not.

Thanks Acid, looked at it and will try that installation process.

Now Let talk about security, is this programme exposing any danger/vulnerability? Thanks

well it's opening up ports on machines to other devices, so in as much as that is always a risk, yes.
