Keep SSH Sessions Active, Or Reconnect?
borjonx writes "Is it safer to log out of an SSH session, and re-establish it later, or just keep the connection open? Like many of you, I use OpenSSH to connect to my Slackware Linux boxes remotely from Linux and WinXP (putty.exe) clients. At home and at work, I wonder if it would be safer to just leave the connection open (my clients are physically secured, the servers limit connections with hosts.allow). Is it more secure to re-establish the connection over an insecure link (big bad internet) where people can sniff that handshaking, or is it more secure to just remain connected? I connect 1 to 4 times per day, most days."
Just drive a blue car if you want it to catch on fire, you mean. The ONLY time I have ever had a car catch on fire it was blue.
Are they using the interwebs to hack the mainframe, or crack the mainframe? You need to consider if they are after your Datasheets or your Hard-Diskette. Theres so many factors to consider. Perhaps they just want to plant a worm that will grow into a virus which will grow into a trojan, if you don't stop it in its Larval stages. You can use cyber worms and cyber Larva in some advanced Phishing techniques, so don't waste them if you come across them. I suppose the only way to be sure 100% secure is to encrypt your entire house on the molecular level. Before you head off to work, you should arrange each everything into 8 mol groups and hash into some kind of cipher, its the only way to be both virtually and physically secure.
Are you crazy? Obviously the two encryptions would cancel out each other!
Switch back to Slashdot's D1 system.
When you cross the two encryption streams you may get total protonic reversal, or you may get 1 REALLY POWERFUL STREAM.
How much is your data worth? Back it up now.
The only car I have ever seen on fire (in real life as opposed to on TV) was a Porsche - and it was blue.
And I currently have two laptops that I amd repairing - both of them have buggered screens.
Oh, and then there's the "Blue Screen of Death" - though I've only seen one PC burst into flames after a BSOD, so that was probably a coincidence...

I've had two cars catch fire ... both blue!!! I think you're on to something ...

Yes, you are correct, but you may want to upgrade from ROT-13 to ROT-26.

If many of us are connecting to your Slackware boxes, reconnecting is not your largest vulnerability!
(sorry, couldn't resist)
Ideally, you would to verify that fingerprint with a version you get through alternate, presumably secure, means. E.g. an over-the-phone conversation with an administrator
So what if this administrator you're having such a secure conversation with has someone holding a gun to his head! Guess you're not so secure now, huh?
