Submission + - Deleted cloud files can be recovered from smartphones, researchers find (infoworld.com)

tsamsoniw writes: "Researchers from the University of Glasgow have discovered that they could fully recover images, audio files, PDFs, and Word documents deleted from Dropbox, Box, and SugarSync, using both an HTC Android smartphone and an iPhone. They created 20 different test files, including Words docs, PDFS, and JPGs, uploaded them via a PC to the various services, and synced the services with the mobile devices. They accessed and manipulated the files in varying ways (e,g accessing them online once, saving them offline), then used a forensics toolkit to attempt to reconstruct files with artifacts saved to the phone."

They're not going to do that. The director of Windows server development at Microsoft even gave us a quote for the Samba 4 press release.

https://www.samba.org/samba/news/releases/4.0.0.html

For the tl;dr crowd:

"Active Directory is a mainstay of enterprise IT environments, and Microsoft is committed to support for interoperability across platforms," said Thomas Pfenning, director of development, Windows Server. "We are pleased that the documentation and interoperability labs that Microsoft has provided have been key in the development of the Samba 4.0 Active Directory functionality."

Thanks a *lot* Thomas !

No, I also know when it was first widely adopted. I was around and shepherded it through that remember. It really took off around 1994 when we had very wide use on SunOS and early Solaris use.

Wider Linux use really didn't start until about until 1996 or so. I remember tridge and I being amazed that making it work on Linux became more important than making it work on SunOS/Solaris/HPUX and other commercial UNIXes.

No, you're getting the history the wrong way around.

Samba was started in '92. The web wasn't on most companies radar until the late 90's.

Web and database on Linux came in the door opened by file servers :-).

Our original platform was SunOS (not even Solaris). When Samba started Linux was a toy, it didn't even have networking.

It's all in how the server is configured, and if the client will pipeline requests.

I can easily saturate a gigabit network using modern Linux CIFSFS and Samba. Ensure you turn on pthread based aio on the server, and the client now issues multiple outstanding read/write requests.

SMB2 makes this easier as it does this by default even on Windows clients. Ensuring your server has the pthread-based aio is the key though (depending on server CPU availablilty - on low end systems some OEM's get more mileage by using zero-copy sendfile/recvfile instead).

You do realize that many enterprise storage servers made by companies like IBM, Symantec, EMC, Dell etc. are or have been based on Samba code, right ?

Nah, probably not... :-). After all, you know that only Windows storage servers work with Windows clients don't you :-).

There isn't a court-ordered requirement for them to test it. There's a market enforced requirement :-).

Go into Frys (or local Geek store). Look at all the NAS boxes on the shelf. That's all Samba. Every one.

Now imagine you're Microsoft. A new version of Windows comes out and it doesn't work against all the "home NAS media servers" people have. Ooops :-(.

They test against Samba *all the time*, as it's good for their business to do so.

They also go a little above and beyond by helping test the AD server part of Samba (which isn't in wide production use yet) - they do that in their interop labs up in Redmond.

They provide free food for the engineers working late up there. It's not as good as the free Google food (but then again, hey - what is ? :-) :-).

Oh you mean corporations like IBM, EMC, Netgear, WDC,Google ? Yeah, the GPLv3 really scared them :-).

Listen to my presentation here:

to explain why GPLv3 is a *better* license for commercial use the GPLv2.
