Re: [gentoo-user] CLI Torrent client(s)?
On 29 December 2011, at 11:07, Pandu Poluan wrote:
I'm wondering: what's your recommended CLI Torrent client(s)? And why?
deluge.
I believe that when I checked it was the only client that could be run in
daemon and client mode.
The CLI front end isn't perfect, but it's ok, especially once you get used to
using the pageup / pagedwn keys (and working out the function-key equivalents
on a cramped MacBook keyboard).
`deluge-console` starts the curses interface and once it's running you can run
commands like `info` to show the status of torrents (use `info abce123` to show
the status of the torrent for which the hash begins with abc123). However you
can also run `deluge-console info` at the command line and grep the results. To
add parameters to commands applied from the bash prompt you need to quote them
- e.g. `deluge-console 'config -s max_download_speed 150'`
I mislaid my installation notes from a few months ago, but basically you emerge
deluge and have to create for yourself a deluge user, with limited permissions
and a home dir of something like /media/Torrents/. Edit /etc/conf.d/deluge to
accommodate this user and start the daemon.
Next you start the UI as the deluged user - I can't recall if this involved
`sudo -u deluge deluge-console` or whether it involved giving the user a shell
(afterwards return it to /bin/false) and `su - deluge`, but you will find a
~deluge/.config/deluge/ is created. Exit the client, stop the daemon and copy
this and all its contents to your own homedir (~stroller/.config/deluge/),
making sure you set ownership to yourself. Now when you start deluge-console as
your own user (having restarted the deluged daemon) it will connect using the
deluged credentials.
Caveats that I can remember are that you add your own user to the deluge group,
and you need to set permissions (umask?) on ~deluge so that files / directories
are created 660 / 770 (or at least readable). When a torrent finishes you copy
it from /media/Torrents/ to /media/Videos/ (or wherever) and then use the
deluge UI to delete it; the files are then removed from from /media/Torrents/.
When you add a torrent its torrent file is stored in as
~deluge/.config/deluge/state/abc123….torrent (where abc123… is the hash);
deluge has a function that can monitor a directory for new .torrents, and I
just made this directory ~deluge, then added the below to my .bashrc:
function torrent {
if [[ ! -n $1 ]] ; then echo Torrent what file? 2 ; return 1 ; fi
while [ $1 ] ; do
if [[ ! -e $1 ]] ; then echo $1 isn't a file! 2 ; return 1 ; fi
if [ ! $(file -b $1) == 'BitTorrent file' ]
then echo $1 appears not to be a BitTorrent file! 2 ; return 1 ; fi
chmod 666 $1 mv $1 ~deluge/${1##*/}.torrent
shift ; done ; return 0 ;
}
These permissions allow deluge to keep its homedir clean - it can delete files
belonging to you, and create copies in its state folder. Alternatively you
could share the folder over Samba and ensure the permissions that way.
You ask specifically for a CLI client, but the gtk front end is really pretty
acceptable, and having already copied the .config/deluge/ stuff you can use it
over ssh X11 on your Apple Mac. The first time you might need to go into the
app's prefs, enable show remote servers and connect using the new button that
appears in the toolbar. You can install the scheduling plugin using the gtk
client and arrange for your downloads to only run at offpeak times; once this
is saved you don't need to use the gtk client again. There's a webinterface;
it's a bit shit (in 1.3.2, I haven't tried it in 1.3.3; I think some
improvements are supposed to be coming) but it's ok.
I think I've used Enhanced CTorrent in the past on an old system - it seemed to
work ok but I think it has some flaws; it's been at least a couple of years so
I don't remember the details. I think it's rtorrent that everyone raves about
as the best command-line client, but IIRC you fundamentally have to run it
inside a tmux or screen session, and thus you can't have it initiated at boot
(not reliably, at least); it also doesn't have a separate daemon, and IMO this
is just iffy. On a headless box you're going to have to ssh in as the rtorrent
user, or run it as you and leave your files and privileges exposed. Yeah, as
far as I can see, most authors of BitTorrent clients overlook best practices
for security because it isn't a real service or, uh, no-one's actually looked
for exploits yet. Not that they've disclosed publicly, anyway.
deluge was the only client I could find that addressed this security issue
properly, was well enough supported and which had a good selection of clients.
I did look at, and try, Transmission; I can't recall why I rejected it.

I imediately associated it to the lack of free RAM, but I always rushed to check the RAM usage with htop and it were never really high. So today I decided to turn my swap partition off. And the system is FLYING. I mean, it's pratically a new machine, now it's usable and reliable. I thought of falling back from KDE 4 to awesome (tried it earlier in an old notebook last year) given the memory footprint of KDE, but it seems that my hard disk was the culprit here. I've heard that Linux need a little swap partition, maybe just 512MB, for some tasks, but I'm not going to turn it on anytime soon. It's a desktop machine, 24/7, and I couldn't care less about suspend-to-disk. So, should I ban swap partitions entirely from my life? Is that ok?

This question comes up about every three months or so, and the end result is always the same: the same people chip in with the same answers and we all come to the same conclusion. You should check the Gentoo archives for the most recent gigantic thread on this, that one was particularly illuminating. But to summarize: You haven't given any real info for people to answer your actual question. To do that, we need to know what exactly your machine is doing and why, please what your swap settings are. Generally, the kernel is happiest with a little bit of swap (512 MB is a very much more than a little) and you can get by with that if your apps fit into ram. KDE is reasonably smart with ram usage, if you only have 2G it will try fit into that. If you have 22G it will try to use lots. If your machine was really slow, it was likely thrashing. But no-one can say for sure - what was your disk doing at the time? What did vmstat say was going on? To summarize a summary, the answer to can I ban swap? is maybe -- Alan McKinnnon alan.mckin...@gmail.com

I have swap but only want it used to prevent a lockup or some other bad situation. I have this in /etc/sysctl.conf: vm.swappiness = 20 With a setting of 20, it will use swap but only when it is out of ram. I have 16Gbs of ram in my rig and I wouldn't run it without at least a little swap. Why? Well not long ago I did a update. One of the KDE programs got updated and I was still logged in. It wasn't happy and starting eating ram like a cookie monster. That one program was using over 14Gbs and growing. I was able to kill it before things got to bad but even with 16Gbs of ram and swap, it was dog slow. Another minute or two, it may have locked me out. I would recommend having swap and just setting it to use it when ram fills up. I would also replace that stick when I could too. ;-) Dale :-) :-) -- I am only responsible for what I said ...

Re: [gentoo-user] To swap or not to swap? Is it really needed?
Sorry for being so general, for not giving any real info. I'm new to system monitoring, I just learnt about iostat and swapon -s, now about vmstat. I mainly tried to catch anything unusual in top/htop. Trying to be more specifically, my system is a core 2 duo, dual core 3ghz processor, 4gb of ram (now 2gb), ATI radeon HD4850 with 512mb of vram. I used to play a lot on this box, now a lot less. On Gentoo, when I play is some browser game or cowsay (it's in games-misc!), not anything relevant. I'm using radeon open source drivers, by the way. My main use, currently, is web surfing, firefox with LOTS of tabs, email, social networks and random browsing. Firefox alone uses lots of ram, almost always it's using more than a half GB, sometimes it passes the 1gb mark. I also do Qt develop on this, but nothing heavy. No virtual machines, no 3d rendering, no heavy processing, no hibernation. So, I'm just a basic common web surfer. In this case, can I say it's at least SAFE to disable swap? I'll look into last month's thread on this.

I'll look into last month's thread on this. Safe to disable, sure. swapoff your device(s) and see how it goes. If you start to get out-of-memory errors, you know you've made the wrong decision. :) I think general opinion is that swap is slow and kills performance, you want to avoid it happening if at all possible. If you have enough RAM to avoid using it entirely, great. Tuning the sysctl settings like Dale said, while still having swap partition just in case is the way I'd go. If the system is swapping all the time, maybe you just need more RAM. While you're looking at recent threads, check the one about ZRAM also. It is a good alternative to (or complement to) disk-based swap, if your normal swap usage is less than the amount of ZRAM you've allocated. Some things, like suspend-to-disk, might require a swap device on-disk. I have never used that feature myself, so I'm not familiar with the details.
Re: [gentoo-user] To swap or not to swap? Is it really needed?
ZRAM is a compressed ramdisk for swap, right? I'm really not interested currently. My next system will have 16gb of ram, and I'll create an 8gb ramdisk on it to increase emerge performance. Other than that, I'm pretty happy with my system performance, disabling swap and compositing effects (remember, open source radeon drivers, I might try fglrx again but I really liked KMS) did the trick.

Possible data loss due to that. So, should I ban swap partitions entirely from my life? Is that ok? No. You simply tweak swappiness. In your /etc/sysctl.conf, add this: vm.swappiness = 20 The default value is 60. Which makes the system use swap very early on. With 20, you pretty much will swap only when really needed. I've read somewhere that values lower than 20 are not recommended, but I don't remember where or why.

I don't have it set to a specific amount so it uses whatever it needs. It even works fine with LOo. I have 16Gbs in all but it rarely uses more than 4Gbs.
