If you are running your ssh server on a port different than 21, for example 22, you can connect to the machine like this:
ssh mymachineip:22
or
ssh mymachineip -p 22
However, there is an easier way:
Create the file ~/.ssh/config, then fill it like this:
Host mymachineip
Port 22
Now you can just ssh to the machine: ssh mymachine
When there is only one screen session, screen -raAD attaches to the running screen. So far so good.
However, if for some reason, there are more than one screen sessions, (screen -ls should give you those), screen suggests that you need to do screen -r [[pid.]tty[.host]] to reattach.
However, this simply doesn't work at first and yields weird errors like:
There is a screen on: 5541.pts-1.shannon (11/02/2009 04:40:02 PM) (Attached) There is no screen to be resumed matching 5541.pts-1.shannon.
This is utterly confusing, since it first says that there is a screen, but there is no screen to be resumed. What this means actually is just that however: one first has to detach that screen in order to attach to it. So, yes, there is a screen and that screen is not a screen one can connect directly.
The solution is to give the -d parameter to detach it at first, so
screen -d -r 5541.pts-1.shannon
should work. In fact, I guess screen -r -d 554 works too. That 554 portion has to be unique though, so screen -r -d 5 works too if no other screen session starts with a 5.
Weather information can be obtained at command line using a Python script that retrieves the weather information from Yahoo API found here at GitHub.
For Ankara, the location code is TUXX0003 and I aliased it in ~/.bash_profile as:
alias hava='weather.py TUXX0003 -m c -f 2'
