Linus Torvalds – Philosophy

“If you’re too commercial,” Torvalds says, “you end up being too shortsighted. You have a ‘this is what we need’ mentality, and you blow everything else off. But you want the commercial side, because commercial forces end up listening to different customers and meeting different needs compared to those doing it just for fun.”

bittorrent downloads in the background

If you want a simpler setup, a GUI-less server that download, store and share files and you can move it to another machine later. You could run BitTorrent (the original client) and setup a secure HTTP to download to another machine.

The following command will continuously scan the current directory for torrent files and adding them. When something is done, you can move the torrent file and its newly-downloaded files to another folder, it will automatically be removed from sharing. Check out other parameters you can do with launchmany-console

nohup launchmany-console –saveas_style 1 –max_upload_rate 600 –display_interval 5 . > torrent.log &

( Older version: nohup btlaunchmany.py –display_interval 5 . > torrent.log & )

Redirect crond(pam_unix) syslog messages

If you see too many of these lines:

root@s1 trungson]# tail /var/log/messages
Oct 16 12:36:01 s1 crond(pam_unix)[21821]: session closed for user root

Here is how to redirect it to a more appropriate place

[root@s1 trungson]# more /etc/syslog.conf
...
*.info;mail.none;authpriv.none;cron.none;auth.!=info    /var/log/messages
...
# Log cron stuff, add auth.info to redirect cron logging
cron.*;auth.info              /var/log/cron
