How to Sign Into Two or More Skype Accounts at Once

1 Share

Skype doesn’t offer an obvious way to use multiple accounts at the same time. You don’t have to log out and log back in — you can sign into as many Skype accounts as you want via the web, Windows, Mac, or Linux Skype applications.

RFC 7568 Deprecates SSLv3 As Insecure

1 Share
AmiMoJo writes: SSLv3 should not be used, according to the IETF's RFC 7568. Despite being replaced by three versions of TLS, SSLv3 is still in use. Clients and servers are now recommended to reject requests to use SSLv3 for secure communication. "SSLv3 Is Comprehensively Broken," say the authors, and lay out its flaws in detail.

It's all fun and games until someone [XOFF]

1 Comment and 4 Shares

Way back in the dark ages of Linux, I had a bunch of machines which didn't run X. They were strictly text mode, and sat there doing whatever I needed them to do: routing, DNS, dialups, mail, RADIUS auth, you name it. There were plenty of daemons working for me, and most of them had things to say via the syslog.

To keep an eye on things, I would just watch the syslog by tailing files like /var/log/messages. That was all well and good, but it meant having to be logged in. If I was logged in, then there was a console open, just a single ^C away from giving a shell to anyone who came by. This was before the days of "cheesing", "Biebering", or "jelloing" unlocked terminals, but I still didn't like it.

One day I noticed that you could create a new text console on a Linux box just by shoving some data at the right /dev entry. Just "echo" something to /dev/tty12, then ALT-F12 and you'd be able to see it. Prior to that, ALT-F12 would do nothing since it didn't exist yet.

From that discovery it was just a hop, skip and a jump to having syslogd write a second copy of everything to /dev/tty12. Then I could log out, flip to that virtual console, and watch things that way. Any time I wondered what was happening, a quick tap on the keyboard to turn the screen back on would let me see without logging in.

That's how it went for a while, but then one day basically everything on that machine stopped responding. It's been a long time so I forget exactly transpired in the middle, but eventually it came down to one thing: my keyboard's scroll lock light was glowing at me when I was on tty12.

Yep, that key that basically has been a part of the PC keyboard layout forever and never really did anything finally had a purpose, and on Linux, it served to stop writes to a text console. This was all well and good in theory, but since syslogd was doing blocking writes to it, that also meant syslogd would get jammed. These days, that wouldn't be a problem, but back then, /dev/log was connection-based.

When syslogd got stuck, it stopped reading /dev/log, and eventually that became a trap, too. Anything trying to talk to it also blocked. Given that sendmail and a bunch of other things all called syslog(), this made for a pretty messy situation.

Someone had pressed the scroll lock key on the keyboard while that tty was active. Maybe it was me, or maybe it was something fooling around, or maybe it was just the cleaning crew "doing me a favor". It doesn't really matter.

...

What inspired me to write about this today is stumbling over something similar not too long ago. I have a couple of programs which run in screen, mostly out of sheer laziness on my part. This is fine until you accidentally hit ^S while attached to it. ^S is XOFF, or for those of you who are lucky enough to not have to know this... is part of software flow control.

Yep, ^S, 0x13, decimal 19, DC3, whatever you want to call it, is usually interpreted as XOFF. It'll sit there and block writes until someone sends it ^Q, 0x11, decimal 17, DC1, which is XON. Really.

Anyway, let's say you're in screen, which by default uses ^A as a command key. ^A N goes to the next screen, ^A D detaches, and so on. If you're on a vaguely QWERTY-ish layout, you'll notice that A and S are right next to each other.

It's not much of a stretch to imagine accidentally hitting that S instead of A. At that point, all of the writes block until you either unwedge it with ^Q or bail out of screen. If you didn't know what was going on behind the scenes, it might just seem like "one of those things that happens sometimes".

If you've ever wondered why some folks hit ^Q any time things seem to have frozen in their terminal, this might be why.

Heh, I still worry about Xon/xoff constantly when I'm working on this sort of thing. I try to turn it off on my terminal packages when I remember.

Time Out of Mind - Trailer
TIME OUT OF MIND, from Academy Award nominated Award-nominated writer/director Oren Moverman (The Messenger, Rampart), is a haunting look at life on the streets streets, immersing viewers in one man’s daily quest to survive. Richard Gere delivers a soul-baring performance as George, a man whose struggle to find food and a place to sleep in New York City is beautifully captured with remarkable realism and heartrending compassion. Shuffled into the unforgiving bureaucracy of a men’s shelter, George seems destined to wind up as just another lost soul swallowed up by the system—until he meets a gregarious, down-and-out ex-jazzman (played by Broadway legend Ben Vereen) who inspires George to reconnect with his estranged daughter (Jena Malone). Cinematically stunning and shot in an eloquently observational style, Time Out of Mind is an unforgettable plunge into a world that is all too easily overlooked.
Directed by: Oren Moverman
Starring: Richard Gere, Ben Vereen, Jena Malone, Kyra Sedgwick, Jeremy Strong
