SDPSeed - Automated Seedbox

Overview

The SDPSeed project provides the design for a server that will:

• Scan a remote file share periodically for new or updated "SDP Packages" (essentially, each 2-level-deep path on the share is a package)
• Generate torrent files for packages over a certain size
• Start seeding automatically
• Move the torrent file to a remote server so it can be accessed by SDPFetch or another bittorrent distribution method/client.

Operating System

• The seedbox was built on RHEL 7.1, but implementing on any modern linux OS with should be possible.

Base Install

• yum update
• yum install nano cifs-utils screen perl-CPAN
• yum group install "Development Tools"
• groupadd sdpseed
• useradd –m –s /bin/bash –G sdpseed seeder
• mkdir /etc/sdpseed
• mkdir -p /var/sdpseed/{torrents,watch}
• mkdir /mnt/remote-storage
• chown -R seeder:sdpseed /etc/sdpseed
• chown -R seeder:sdpseed /var/sdpseed
• chmod -R 770 /etc/sdpseed/
• chmod -R 770 /var/sdpseed/
• chmod 775 /var/sdpseed/torrents
• nano /etc/yum.repos.d/epel.repo

• under [epel] set enabled=1; save

Perl Modules

• cpan
• install Convert::Bencode_XS
• quit

rtorrent and mktorrent

• yum --enablerepo="epel" install rtorrent
• yum --enablerepo="epel" install mktorrent

Scripts

• create_db.sh, scan.sh, repath.sh -> copy to /home/seeder

Configuration Files

• rtorrent.rc -> copy to /home/seeder/.rtorrent.rc
• sdpseed.conf, credentials.txt -> copy to /etc/seeder
• fstab -> add contained line to /etc/fstab

Edit Configuration

• edit /etc/sdpseed/sdpseed.conf:
• replace TRACKERURL:PORT with your Tracker URL and port
• edit /etc/sdpseed/credentials.txt:
• replace COMPLETE_ME! with username, password, and AD domain
• edit /etc/fstab:
• replace SERVERHOSTNAME/SERVERSHARE with your SDP server's host and share names

Increase CIFS Max Buffer

• edit /etc/modprobe.d/cifs.conf
• add line: cifs CIFSMaxBufSize=130048

IPTables Firewall

• iptables-save > iptables.rules
• nano iptables.rules
• Add before reject all:

• -A INPUT -p tcp --dport 51000:52000 -j ACCEPT

• iptables-restore < iptables.rules

• verify it worked

• iptables -L

Finish Install, Scan SDP, Create Torrents

• mount /mnt/remote-storage
• su seeder
• cd ~
• chmod +x *.sh
• ./create_db.sh
• ./scan.sh
• mkdir .rtorrent
• mkdir scanlog

Launch rtorrent

• screen rtorrent
• use ctrl-{a,d} to demonize
• to restore rtorrent:
• screen –r

Setup CRON Job (scan SDP every 2 hours)

• crontab -e
• 0 */2 * * * /home/seeder/scan.sh > /home/seeder/scanlog/log 2>&1
