I'm trying to ascertain if I am at risk...
About 1 week ago I connected to the University of Minnesota's "guest" wifi network. I was asked to provide an email address and that's all. I was online.
But I use Little Snitch so granted access to a flurry of temporary connections to when they popped up as I was in a rush to connect. Possibly a bad move, but I was guided through this process by a U of MN tech guy so I felt ok about it. It worked for the weekend and that was that. I didn't use my email or login to any websites, I just pulled up a YouTube video for a group's presentation.
All seemed well... But, when I got home, I received 2 Little Snitch notifications: NetAuthAgent and nmbd. I don't know if any of this is normal but NetAuthAgent showed up as ~myusername but nmbd showed up as root.
Also, my hard drive space also went down to zero on a random instance when Safari froze up, but I don't have a screen grab of that.
Also, in my Finder, there was a "PC Server" device listed under Shared. This was new. This freaked me out.
Not only have I been unable to stop NetAuthAgent and nmbd from prompting me for access every single time I start my computer, the times I have experimented/troubleshot the issue and give them permission, I'm getting the PC Server listed under Shared.
I've run MacScan and I can block it out by denying it access via Little Snitch, but I wanted to ask the digital Jedi out there if this was normal, because when I try to click "Connect To", it give me the following error...
I've seen NetAuthAgent & nmbd before, but not like this.
In summary, these instances started happening constantly after I used the University's network and has not gone away.
Thanks in advance for your time,
P.S. I'm running the latest software on a MBP, 17" (Mid '09)
your proxy settings are exactly like mine, so they seem alright, and probably didn't need to be deleted. I can't find the 'use passive ftp mode' setting, but that shouldn't by itself make a difference - all that might do is allow you to log into a server anonymously, or (if you have your machine set up as a server) allow others to log onto your box anonymously. You might try the obvious - command-drag the odd server off of your sidebar and see if the problem goes away.
Form my experience, universities (because they deal with large numbers of clueless incoming teens) usually have draconian safeguards against viruses, hacking, trojans, and other general computer ills, so I would not worry about having gotten mucked while connected there. Anything's possible, but it's much more likely that something innocuous got set that just needs to be unset.
