Install phploc on openSuSE 11.3 [HOWTO]

Once you've got PEAR installed, run these commands (as root):

pear channel-discover pear.phpunit.de
pear channel-discover components.ez.no
pear install phpunit/phploc


At first I was getting errors:

phpunit/File_Iterator requires PEAR Installer (version >= 1.9.1), installed version is 1.9.0
phpunit/phploc requires package "phpunit/File_Iterator" (version >= 1.2.0)
No valid packages found
install failed


But running:

pear upgrade-all


fixed all the errors.

Use ssh-copy-id on a non-default port

ssh-copy-id has known problems with handling non-standard ports (e.g. connecting to a different port than 22). To overcome this issue, use a command like:

$ ssh-copy-id "user@host -p 6842"

HOW TO Install MetaTrader 4 on Linux

How to run Meta Trader 4 on Linux using WINE.

1. Sign up for an account at a forex broker, and download their MT4 installer. I used Easy-Forex, but this procedure should work for any version of Meta Trader 4.x.
2. Install wine on your linux machine (I used wine 1.1.44 on an openSuSE 11.2 machine). Also download winetricks (used to install additional libraries required by MetaTrader).
3. If you haven't used wine before, run 'winecfg' to create your installation directory. You can then click 'OK' to exit the dialog, or have a look around at the options (I used the defaults).
4. Start up a Windows computer, and copy all the files in C:\WINDOWS\Fonts into the wine directory (/home/username/.wine/drive_c/windows/Fonts)
5. Run winetricks to install mfc40 and mfc42:
     sh ./winetricks mfc40 mfc42
6. Run the MetaTrader installer executable.
      wine ./mt4setup.exe

That's it! You should now be able to run MetaTrader4 by clicking on the icon on the desktop, or running the following command in your Linux shell:

wine /home/username/.wine/drive_c/Program\ Files/yourmt4installdirectory/terminal.exe

If you have any more problems or questions, please contact me by leaving a comment. MetaTrader is running fine for me under openSuSE 11.2 with the latest WINE from the repositories, once MFC40, MFC42 and the correct fonts had been installed.

Appendix:
When you first start MetaTrader4, it might take a while to initialise. You'll see something like the following in the shell output:

Mounting Filesystems by UUID - Ubuntu

Ubuntu 9.10 automatically mounts hard drives by UUID when it's installed. This means that if you insert a new hard drive, which changes all the /dev/sdxx numbers, your system will still function normally. Linux by examples has a good tutorial on common fstab commands for uuid.

To find all UUIDs:

ls -l /dev/disk/by-uuid/

To check the UUID for a known device:

sudo vol_id /dev/sda1

or this:

blkid /dev/sda1

How to extract / unzip a .tar.gz file into a different directory

What happens if you need to extract a .tar.gz file, but don't have enough free disk space in the directory? It might show you an error like this:

tar: Wrote only 9216 of 10240 bytes
tar: Skipping to next header
tar: Error exit delayed from previous errors

Tar and Gunzip will only extract into the current directory. Here is a command that will unzip a .tar.gz archive into a new directory.

cd /new-directory
gzip -dc /path/file.tar.gz|tar xvf --
