[arm-allstar] How to install Screen

[Doug Crompton]

Ron,

 It is always fun to play if you have time. Here is a link to archived system code. You might find what you want there,

Packages can be installed from a local folder with pacman.

pacman -U /download_path/packagename.tar.xz

Doug,Thanks for the suggestions. When you have putty windows open and the computer loses power or the gateway connections drops, then those processes still exist on the computer you were connected to. If you had opened Screen from the Bash shells in the ssh connections, you would be able to reconnect and reattach those screens as though the connection were never lost. Or of course you could use ps -u root and close those processes down and/or possibly reboot.  Screen is also useful for collaboration with another person by sharing the named screen terminal.  
You are right, what have I got to lose except some writes to a spare SanDisk card.73,Ron MorellKA7U

   Ron,

  What often happens when trying to load new packages is that the base packages are not up to date. Doing a complete update can break things and would require a dahdi recompile.

In lieu of screen you know you can open as many windows as you want in putty or winscp on a remote system. I generally have 6 or more putty windows open, to different or the same servers.

However if you do want to play I would suggest making a backup of your image to another SD card. One you can boot up and play with and if you break something it is no big deal. You can't hurt anything.

On the backup card when you download a package and it gives you an error try  - pacman -Sy <package-name>
This should work but in some rare occasions could break things.

If you get it working and everything seems to work you can just use that image. You always have a backup (your original) to use if a problem arises.
