Axel
Axel tries to accelerate downloads by using multiple connections (possibly to multiple servers) for one download. Because of its size, it might be very useful on bootdisks or other small systems as a wget replacement.

Recent commentsIt's me again, this time with another patch. Cookies don't work well, but i think this is better.
By using multiple threads axel is really fast in the beginning but it becomes slow near the end of downloading. This is because some threads have already finished, while others are bit slower. This patch will reactivate threads to divide parts of file that are left.

Here is a buggy patch for loading cookies from Firefox 3

Hope it works and that you will like it.
Hiding password to users
Here is a way to hide the password to other users on the same server with axel when downloading a file from an ftp account.
Just type this kind of command:
echo ftp://user:password@ftp.server.org/myfilename |axel -n 5 -
(note the trailing dash '-' at the end of the axel command, else it won't work).
This will pipe the command to the axel stdin, and doing this, the password isn't showed in a 'ps' command. Thus you should always use this kind of commands if you are downloading from a server with many users.
Enjoy!

Incredibly fast !!!
This Axel download accelerator for linux is simply absolutely great!
I get much faster connexions with this than with wget.
Here is what I get on my side (for the same file, same server, same computer client):
wget: 238 Kbytes/s
axel: 686 Kbytes/s
This is almost times faster..
It is normal due to the fact that it triggers several connections on the same file, rather than only one connection.
Almost all connections are limited to about 100-200 Kbytes, I don't know where this limitation comes from, but I realised this already with other downloaders.
This is why Axel is so important if you want very fast downloads! (I have to download 5Gbytes of data regularily and it decreases the time from 6 to 2 hours).
Also, with the new fast private connections of up to 15Mbits/s or more, axel will become even more important, because the limit will probably still stay at 240kbytes/s with wget, as it will go well over 1500kbytes/sec with Axel!!
Also, wget will NEVER add several simultaneous downloads as with axel, because they told me this directly.
Therefore, I can only recommend this software and it's continuation. Congratulations to Wilmer!

Great!
I´ve just tried Axel, as I had a download scheduled to last 20 minutes, and I had only about 7 minutes left to leave office... well, the same download was finished in exactly seven minutes :-)
Don't know about you guys, but it worked for me. Maybe there are times when it won't work, but at least sometimes it DOES work, so I like Axel. It simple and it works. Thanks to the developer!
