This should help. There's a slight issue with these two file. They are the same filename. I recommend something like the following:
$
Then you end up with two different file names.
$ ls -l *20150223.txt.bz2
-rw-r--r-- 1 martin staff 143014687 Mar 28 03:06 measurements-meta-20150223.txt.bz2
-rw-r--r-- 1 martin staff 425607 Mar 28 03:07 probes-meta-20150223.txt.bz2
$ gunzip *20150223.txt.bz2
$ ls -lh *20150223.txt
-rw-r--r-- 1 martin staff 2.8G Mar 28 03:06 measurements-meta-20150223.txt
-rw-r--r-- 1 martin staff 4.4M Mar 28 03:07 probes-meta-20150223.txt
$
The files downloads were fast when in the RIPE room -- 30 seconds.
Enjoy,
Martin
