Hi all,
Did anybody already download and use the skype P2P telephony tool ? Heard
that its relatively nice, however do I have my concerns about the securiy
inside, they talk about end-to-end enreyption, but as it's closed source I
can't really check its quality.
Has anybody knowledge about the quality of skype's security ? As it's a
Luxembourg company, my interests are of courye also on a professional
basis ;)
thanks for any answers, links, etc.
ciao,
pst

My wife costed me about 150 EUR a month in international calls using
CrossComm.
I'm still maried, and she still has capacity to use a phone, so I had to
find a solution to reduce the recurent costs, or buy a phone company, or
suppress phones at home.
I tryed Skype (my engagement for free software would lead me to use
GnomeMeeting, but the price of calls to fixed phone with it is twice the
price of Skype).
I invested in headsets. I even tryed to find a dual-way wireless
headset. Not yet available at acceptable price.
The result is: 50% of the time, the communication is acceptable, using
SkypeOut (so to legacy phones). My bill got reduced to 70 EUR, because
my wife switches to the phone when Skype is not delivering the espected
service. So you can conclude that Skype is a good service, knowing that
it is still (and will remain) no more than a BEST EFFORT service. For
2EURc/min, it's 5 times cheaper than CrossComm, so you have value for
your money.
I informed my wife about the period in a day where the Internet is less
loaded, and she follows now my advice, and I think it increases the
efficiency rate of Skype service.
I have no info about Skype security. Believe me, the stategic value of
informations exchanged between my wife and her mother is close to 0. I
don't really care about this, but when they talk about me. If you have
concerns about Skype at security level, check the web about experiences.
I didn't heard about any issue there until now. You can also consider
running Skype in a sub-system (User Space Kernel) or under a very
limited account (nobody). But I think they don't want to play this game.
I think there is much more risk at using eMule or Internet Exploder.
Yours,

Pascal, I've been fairly happily using Skype on Linux for several months now.
I can't say just about security as there really isn't a way for me to check
(I haven't been hacked yet).
However, I can say that Skype for Linux still isn't very mature. They do not
support alsa, so you have to run the skype binary through artsdsp. Most of
the time it works fine, but occasionally, I have some really bad delays in
the line (10 or more seconds). This only occurs when I am talking with my
wife who is also running skype on a Linux box. Interestingly, despite Skype
being Headquartered in Luxembourg (I'm pretty sure that it is the minimal
legal staffing there) Luxembourg is the most expensive country in Western
Europe to call using Skype Out.
At present Skype doesn't have the capability of receiving phone calls from
traditional telephones. Though it can place calls to them. They are
supposedly working on this though.
Now, if you are looking for an open source and open standard solution, take a
look at www.sipgate.de for a publically accessable PBX. You can then use
something like linphone or kphone to connect to it. Also, if you are really
advanced and you happen to have a VoIP phone sitting around, you can connect
it direct to the internet. Sipgate offers German and UK based phone numbers
that are accessable from normal phone lines and there are a number of other
similar organizations around if you don't like sipgate.
The two big advantages of Skype over sipgate are that it "just works" so, NAT,
proxies, and firewall rules are not much of an issue. sipgate can be a pain
to configure if you don't know what you are doing.
Now, if you are a hopeless networking nerd like myself, then check out this
technical report on the skype protocol from a student at Columbia University:

have you checked the recently released skype ?
i had problems with arts too, so i made a script which calls "artsshell
terminate" and then skype. that way skype uses OSS and everything's fine.
currently i'm using kde3.4-b2, and have arts completly disabled, so no more
problems for me.

My 0.5 eurocents: I'm using Skype for hours-long calls to a
Linux-running computer in Belgium, and I never had this kind of problem.
I think your symptoms is not only Skype or Linux related.

I did find a aper about skype (with some security aspects) :

does nice except for some eavesdropping vulnerabilities which is not so
nice ;)
