Use the integrated client , MLDonkey, to download files from different protocols simultaneously like bittorrent, edonkey, gnutella on Ubuntu

1.install mldonkey

sudo apt-get install mldonkey-server

2. MLDonkey will automatically create hidden necessary directory and files under the user's home when first run

# run silently in background
# mlnet &> /dev/null &
mlnet

3. with default setting, MLDonkey listens port 4000(telnet), 4001(gui), 4080(web) and allows only localhost so you may need to edit the list of IP address.

# if run mldonkey as root, the config files would be in /var/lib/mldonkey/
vi /home/user/.mldonkey/downloads.ini

.
.
allowed_ips = [
"127.0.0.1/0";] # mask 0 allows any ip
.
.
gui_port = 4001
http_port = 4080
telnet_port = 4000
.
.
max_hard_upload_rate = 10 # global speed limiting, KB/s
max_hard_download_rate = 0 # global speed limiting, KB/s
max_hard_upload_rate_2 = 5 # for bandwidth toggle
max_hard_download_rate_2 = 20 # for bandwidth toggle
.
.
