sslh – ssl/ssh multiplexer

sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.Probes for HTTP, SSL, SSH, OpenVPN, tinc, XMPP are implemented, and any other protocol that can be tested using a regular expression, can be recognised. A typical use case is to allow serving several services on port 443 (e.g. to connect to ssh from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port.

Launch GUI from terminal

I just installed Ubuntu 12.10 x64 onto an unused laptop and reconfigured GRUB to launch to a terminal instead of the GUI as I quite often just want to run some commands without all the other stuff loading and slowing me down.
When I decide I want to launch the GUI (I've changed to Cinnamon by the way) I type STARTX and the GUI launches, but it is missing the taskbar/menu at the bottom of the screen. I can right click and select different items, but am hoping someone has an idea as to why the GUI doesn't launch properly.
If I reconfigure GRUB to boot straight to GUI then it launches properly, so I am fairly sure that it is all configured appropriately.
Thanks for any suggestions anyone has.

No wireless

I have been using Ubuntu for a year and a half. Since Hardy Heron. When I installed it my wireless worked immediately and never had a flaw. I have always updated when the alerts came along. The last update was one that completely changed my desktop and the way things work. I am getting used to a lot of it but my wireless stopped working. A box opens up and asks for authentication. I fill in the password and after a second or two a box appears that says connection established. After about 5 seconds the connection is lost and the authentication box opens again. I have been trying to login for days. I have restarted several times with no change. The new operating system is Ubuntu 12.0 4 LTS. My computer knowlege is very limited. Chances are if you ask a question it will be necessary to instruct me how to find it on the computer.

Ubuntu Live Disks

Greetings, new to your forum.
I read about the Ubuntu Disks you had for a give away and tossed due to lack of concern. Please anyone, don't throw out you old versions of Ubuntu on disks, I collect them to rescue poor sick Windows laptops/notebooks. Wish I had found this site before you tossed them.
