#69802 — Anything to be worried about?

I am currently on a cruise and using the Wifi on the ship. When I sign 
on to their Wifi, I get new things popping up in my shared area. Two 
have a monitor icon, one a computer icon (and this one is a MacBookPro 
according to the name. One says it is guest. 
   I am running a MBP using 10.8.5. In system preferences, I have remote 
manager off, allow access only to my administration name, printer 
sharing is the only thing ticked on. I have NOT checked that it is okay 
to control screen or anything else in that box. The changes are locked 
in the sharing area.
    should I be concerned? Anything else you need to know? Anything else 
I need to do to up security?

When using public WiFi you should have Firewall activated.  (Sys Prefs, 
Security & Privacy, Firewall).

If you mean by your first para that someone or something has deposited 
files in your public folders I would use srm to eradicate them out of an 
abundance of caution.

I took the "shared area" to mean the SHARED heading in the sidebar of
Finder windows.

If I'm right, then those are not of any concern. They are other
computers on the network which have sharing services enabled. The
monitor icons are most likely to be PCs running Windows. The MacBook Pro
which can be seen has file and/or screen sharing enabled.

Those icons can be used to connect to the other computers. If you don't
intend to do that, they can be ignored. If you don't want to see them,
you can hide the entire SHARED category, but I don't recommand that.
Another option is to rerrange the order of sections in the sidebar, so
SHARED appears further down and isn't as obvious.

As for having printer sharing enabled: that will mean the computer is
visible at least to Macs on the Wi-Fi network, via their print dialog
(in the form "Printer Name @ Computer Name"). If you don't want others
on the network seeing your computer or attempting to use your printer
(even if they can't actually use it, due to not knowing your account
name and/or password), then turn off printer sharing.

I second Alan's suggestion of turning on the firewall.

On my system, in the Network window of the Finder, I have two icons:  A
monitor labelled "EPSON Artisan 837" and a PC labeled "epson3ede96". 
Clicking on either of them opens a window with two folders,
"MEMORYCARD" and "USBSTORAGE".  They also appear in the sidebar under
"Shared" when "Connected computers" is checked.

The printer is connected via WiFi.

I suspect that is what the OP is seeing (but with different labels).

Most probably so.  But pointed it out as a potential security risk 
coupled to the recommendation of the Firewall being on.

Okay. I had just never seen that before, although about 99% of my work 
is on my own personal wifi where the only other thing I see is my wife's 
computer. Never noticed that before at Holiday Inns, either, but then I 
guess I probably never looked. 
    Anyway, THanks for the advice. I shall try to keep my inherent 
paranoia under control.

It's conceivable that the hotel WiFi gives each room their own, private 
LAN, so you won't see computers from other guests.

And addendum to things to be worried about: (I see your WiFi concerns 
answered)

Cellular data. I was on a cruise from SF and the minute I boarded their 
cell system took over my iPhone, and I was charged exorbitant rates as 
if I were in Mozambique - all while in US territorial waters. Now I have 
to blather with ATT about it. Not happy I didn't turn off roaming the 
second I boarded, but this intrusion was not noticed until too late. 
$300 I have to fight for. (Mostly map data).

    I got dinged for one minute of cell at sea roaming every time I woke 
up my iphone so I always just put it in on airplane mode unless in St. 
Thomas or San Juan (since both are "local" to my carrier. 

Another interesting cruise weirdness.
       I was getting texts from my daughter this time despite the fact I 
wasn't actively signed on to their Internet (although I was using the 
free part of the ship's wifi to download the activities) and had put it 
on airplane mode which should have put everything on hold. Nobody could 
figure out why. This was iPhone to iPhone. Not sure if iMessage runs 
differently and some how are connected. Maybe telephathically?? ;)

iMessage works over wifi.

    On all cruise lines, you have to buy Wifi time to connect directly 
the Internet for things like email, etc. On Princess you can connect to 
the wifi and their on-board server for things like their activities 
calendar, when the bars are open, and other internal type things. Is 
just being on the Wifi and their server enough to get iMessage if you 
aren't specifically signed on to the Internet?

If two iPhones (or whatever other kinds of device you might care to talk 
about) are connected to a single wifi point, regardless of whether or 
not they can see the internet, then so far as talking to each other is 
concerned, they're on the internet. Obviously, trying to connect to 
anything that isn't also connected to the hotspot will fail with the 
usual "So sorry, can't figure out a way to get there" result. If they 
connect to two different hotspots (assuming there's no connection 
between the two hotspots) then they're both going to be "blind" to each 
other's existence.

I am nearly positive that iMessages will not work on a closed wifi
normally. The way iMessages work is they are encrypted on the device,
sent through Apple's server, and decrypted on the other end. That path
requires Apple's servers be in the loop.

 But not in the case of me on the ship off of St. Thomas and my daughter 
in the Tampa airport. Especially since she was probably using the 
Internet connection from the cell provider and my phone was on airplane 
and on the Princess internal WiFi.  Interesting that it still happened.

It depends. iMessages worked sporadically for me last year on a Disney
Cruise. More often than not, it didn't work, but it worked often enough
to make me wonder if they were testing some sort of limited
functionality to push iMessages.

I'll pay more attention this year when we go to Alaska.

  To further confuse the situation, when we turned the cell back on, we 
had a bunch of queued up text messages from others. Weirdness.

We are going on a Viking river cruise this spring. Does anyone know 
what kind of Internet connectivity is provided? And is it wi-fi or 
ethernet?

I don't think Vikings have anything faster than a horse.

No, I didn't see this page. It's buried kind of deep in the menus. 
It answered all my questions, except about tipping. Thanks for 
pointing it out.
