I received a PDF file, and suspect that it is trying to connect a remote server to track me.
I wondered if there is a way to find out if the PDF file is connecting a remote server through the Internet. Thank you very much.
I would mention that "Prevention is always better than Cure" but there are a few ways to do so. I will only mention the most obvious one here.
Scan that file for viruses before downloading, or open it in the sandbox.
If you are really bent on finding out the root cause of the problem, Packet sniffers like Wireshark should help. I don't recommend having these applications as they are commonly associated with hacking, but having an idea of the connections sent across your network would help in knowing if your PDF file is dogged.
But as always, update your Acrobat Reader to the latest version and scan your computer for viruses regularly.

I have installed dropbox python client for linux and I noticed the sync bandwidth is quite limited:
$ dropbox status
Syncing (252,088 files remaining, 18 days left)
Downloading 252,088 files (35.1 KB/sec, 18 days left)
Is there a way to make it faster?
Note: Yes I have a 100Mbit/s internet connexion...
Firstly, check if there is a 75% cap enabled, as mentioned here
If there isn't then it's probably your Internet, try switching to a different network source (from wireless to wired) or use a different Internet connection. I had the same issue before and it was solved by changing to a different Internet connection, yes I have 100Mbit/s too but it didn't help.
Alternatively
If you already have another synced up dropbox, just copy the files over to the new install of Dropbox, if you're just trying to get the initial sync done.
Also take a look at LAN Sync, a feature in Dropbox
This honestly isn't a SO question because is isn't really a programming question, a forum like Superuser.com might be better suited perhaps.
edit: saw that you already have a superuser account, my bad. :)
Can someone provide an example (or a link to one) illustrating how to sync system files (not database) between a local computer and a remote computer/server not on the same network?
Syncing files within the same pc and syncing files between pc's within the same network is straightforward and rather simple. I have those scenarios working nicely.
I need to sync files from "C:\FilesToSync" to a remote endpoint or an IP address. a WCF, HTTP, FTP, or TCP implementation is fine. Just need to learn how the sync needs to be set-up for any of those.
Thanks
this is a really good question. for 'remote' front-end developers / designers like me lol, kinda hard to choose a nicely recommended solution; in some places it's git (OS independent), in certain .NET projects, it's TortoiseSVN-VisualStudio; when i search online, tons and tons of dunno-what-to-choose like BitBucket, GitHub's Fork.
I also am looking for the right 'generic' soln for months now...
Example:
1. working on a soln on one pc, large heavy files, the xml and psd types for instance
2. uploading/synchronising with my remote hosting server for clients
3. backup server on another location, comparing/collaborating/synchronising
some ppl might say 'u know, different projects require different solns, don't cum up with that cr*p please, thanks;
in the end, I use Notepad++ for remote files and my localhost, and Google Drive only for small doc files; meanwhile, winning combo dinosaur-style soln for the laymen in this field ;) ...

My MS access database is located here :
http://192.168.202.1/dbname.mdb
Other computer in LAN network have VB.net s/w installed.
How do I connect to this db?
Thanks in advance :)
Actually, your terminology you using is wrong. You don't connect to a word file. You don't connect to a power point file.
So you have to keep in mind here you are not really connecting to some text file or mdb file that just happens to be sitting on a hard drive.
You are thus simply opening a file.
I mean it is silly to say we connect to a word file, or we connect to a Power point file. So in the case of the office suite and those basic simple files that resides on the disk drive?
We are talking about plane Jane windows file.
A horse is a horse is a horse.
A file is a file is a file.
So you don't connect to the jpg file sitting on the hard drive, you OPEN the jpg file. So if you talking about your current setup it best to use the correct terminology here. You are not connecting to that Access mdb file, but are in fact opening a plane Jane windows file. If you look close at your connection string, it will ALWAYS have a fully qualified windows path name in it that resolves to a file sitting on a folder.
So if you place that file on some server, say web server, then then you still faced with having to open that windows file. This is NOT ANY different then wanting to open a power point file. That means if you going to connect over the internet then you need to EXTEND the windows file system (this means you will need some kind of VPN). At the end of the day, if you cannot use windows networking to brwose and open the folder where that file resides, then you cannot open that file with Access (or more specific in your case the JET data engine).
So for example, if the server where the file resides is a non windows box, say Linux, then you need to "add or use" or "install" the windows file and networking system on that box. A common choice in Linux is to install and run Samba on that computer.
Keep in mind that in the case of using SQL server, then you are connecting to a SERVICE running ON THAT server. In this case then you not opening a file on the remote box, but are simply using a socket (tp/ip) connection to some service. So you not just opening a silly old windows file that happens to be a mdb file on that system in this case.
So as such when you use FTP or http, these are not real "windows" networking systems that allow you to open + use a plane Jane windows file.
So as such, just keep in mind the concept here that you are NOT connecting to some file, but you are just going to OPEN the file.
You need to be able to OPEN the file, and you need to be using the windows networking system to do this open file in the case of Access. I mean, you don't have to install Access(JET) on the target computer. You don't have to install Power Point on the target computer to open a power point file. So you are ONLY opening a file that just happens to be on some other computer.
As such, your path name of http: is not allowed since that is now using http, and not windows file/networking system. As such a path name has nothing to do with windows networking and opening of a simple file sitting on the hard disk. So HTTP or FTP etc. are not based on windows networking and file system.
I don’t think this basic concept is too hard to grasp, but at the end of the day the concept you need to grasp and learn is that when you open a windows file sitting in a folder on the hard drive, then then will you need the windows file system to open such files. The idea and concept of opening a file in a folder might be new to you, but it is a basic requirement and understanding you need to solve this issue.
As noted, you can consider a VPN, but I explain why such a setup is not going to work in this article:
Using a wan with ms-access? How fast, how far?
http://www.kallal.ca/Wan/Wans.html
I suppose another possibility would be to consider the new web publishing ability that Access has. In the following video note how I switch to running the Access application 100% in the browser. The resulting application does not need any ActiveX or Silverlight. So the web pages run + work fine on my smartphone and even my iPad.
http://www.youtube.com/watch?v=AU4mH0jPntI
So you can use the new web publishing feature, and that would allow one to use http: to use the application.
I know you use the C based networking API to do FTP communication but I'd prefer to use something a little higher level. I've seen a few Objective-C based wrappers but I'm not sure what to use. I don't need that complex of FTP interaction. Its just the typical create/delete dirs, upload/download files... What do you recommend?
Edit:
Here is one that looks promising but I can't get it to compile for the iPhone SDK
The ConnectionKit
This may help, but you may reconsider design for reasons stated by bbum:
http://code.google.com/p/s7ftprequest/
The reason why you can't find much in the way of useful FTP client software is because FTP isn't used much any more and is generally actively discouraged from use.
Without great care, it is quite easy to create big old security holes when using FTP (when I ran a consulting company, the 3 times we had infected machines were all because of FTP server security holes or exploits -- one time, the damned HP copier's FTP server was the attack vector!).
FTP is also inefficient unless carefully configured.
I would encourage you to use an HTTP based protocol. WebDAV allows you to do basically anything FTP can do, but does so over an HTTP channel. Thus, it'll work through proxies and the like. Heck -- HTTP has become so ubiquitous that pretty much everything works with HTTP.
And, of course, there are plenty of good HTTP client APIs built for Objective-C.
Obviously, if FTP is a requirement for your project, this answer won't help you much....
After not finding anything that works well I decided I'd go ahead and follow Apple's tutorial on how to do FTP. It sure is a PITA but at least it does work. I'm defiantly going to support WebDAV in the first revision my app, and eventually perhaps some other transfer methods later on. I think I'm going to consider releasing this open source after I get FTP & WebDAV working good, since there is no reason why you should have to do this much low level work to do such a basic and ambiguous task as FTP these days.
I've implemented FTP file download and upload, directory create and directory list download through the regular FTP possibilities in the iPhone SDK. Note: you'd be passing the login name and password as part of every FTP request unsecured. Apparently no apparent connection to the FTP server is maintained at the app level, like with a real FTP client app, that I haven't been able to find for iPhone yet. If you're interested in the source code please let me know through e-mail.
GoldRaccoon isn't mentioned and can be found on GitHub. I use that library and it works very well (besides it didn't support FTP rename)
I am trying to see if anybody is aware of any ssh or ftp ways of editing files in expression web. This is similar to notepad++. I am already aware of sftpdrive option. I am looking for something that is free, and robust.
I have not played with open site feature in Expression Web. I am not sure if this will work well with a php site on a Linux box.
Connect your Expression Web directly to any FTP server in the open site dialog by typing the ftp address in the site name placeholder like ftp://myftpsite.com. Expression web ask you for your login and password and list your folders to begin to edit your files. It’s very easy, no problems at all.
Another option is to use samba or nfs to mount a directory on your local machine. If the server is live, you should restriction connections by ip and/or with a vpn.
Be aware that some editors will lag quite a lot with these solutions though, especially with large files.
