Pacman and Aria2

Hello, I'm trying to get pacman 3.0.3-2 working with aria2, using the instructions from the Arch wiki. It doesn't work. When I use the aria XferCommand, I get the following output

[root@myhost etc]# pacman -Sy

[root@myhost etc]#

When I comment out the XferCommand in /etc/pacman.conf, I get the following output (nothing else has been changed)

[root@myhost etc]# pacman -Sy

Re: Pacman and Aria2

Obviously the problem is due to aria2 not downloading any files.

When aria2 just stays on 0/0 Bytes it often means that the server you connect to is live but you can't get the file. Since most mirrors are ftp server, I assume that you use aria2 in non-passive mode. Try adding the -p option to the aria2c command.

non-passive mode just plain doesn't work in most cases if you are behind a NAT or whatever.

If all that didn't help, try to make a script which outputs the input and output files and the current working directory. Then replace the aria2c XferCommand with that script to investigate the problem more.

I suppose you use
XferCommand = /usr/bin/aria2c -s 2 -m 2 -o %o %u

So the script will look something like that:

#!/bin/bash
pwd
echo $1
echo $2

#out of consideration I never use more than 1 connection per server (please try and add more mirrors instead)
/usr/bin/aria2c -s 1 -m 10 -p -o $1 $2

exit $?

If you save the script as   xfercommand  in /usr/bin/

then your XferCommand will look like that:
XferCommand = /usr/bin/xfercommand %o %u

Hope that helps (but I'm pretty confident that you have a problem with non-passive mode).
