I found a few rtorrent bootup scripts online, but none of them worked on slackware in a drop'n'go fashion.
So, I spent a few hours the other night procrastinating some sleep and modified one bootup script I found to work with slackware.
This rtorrent boot script is "multi-user aware" in that it is designed to work for one specific user of a slackware system. It will start a new "screen" session with the sessionname you specify, then will execute "rtorrent" within that session.
If you intend to have 2 or more users running rtorrent simultaneously, you will need two or more instances of this script: one for each user.
I've placed this script in the following location on my server: /etc/rc.d/rc.rtorrent.tigereye
The ownership and permissions match the other rc scripts there: root:root and 755.
Read through the script and modify the variables as necessary:
Code:
#!/bin/sh
#
# chkconfig: - 99 01
# description: Starts and stops tigereye's rtorrent screen session
#############
###<Notes>###
#############
# This script depends on screen.
# For the stop function to work, you must set an
# explicit session directory using ABSOLUTE paths (no, ~ is not absolute) in your rtorrent.rc.
# If you typically just start rtorrent with just "rtorrent" on the
# command line, all you need to change is the "user" option.
# Attach to the screen session as your user with
# "screen -dr rtorrent". Change "rtorrent" with srnname option.
