this could be the error?

Now it works. The problem was errors on the pendrive. Thank you so much for your support!

Funny. I've just switched to entware and it still has 2.76.1 so much for updated list! By the way your configuration still works!

 

[TeHashX]

Yes, you may use settings.json for entware version too.
Check here the latest version for entware [https://code.google.com/p/wl500g-repo/source/browse/?r=1156#svn/ipkg/openwrt click next until reach transmission.

new version came in today!
a few minor command's changes with entware are:
opkg install transmission-web
opkg install libminiupnpc
The latter wasn't updated and the new version was needed to make transmission start.

 

[TeHashX]

For entware version this commands are enough:

opkg upgrade
reboot

Thanks a lot! This way worked like a charm!
Just one more question. What do you think, can this script run on RT-N66U or there is no chance at all?

See here instructions about torrentexpander posted by ryzhov_al, it's for entware version but should work on optware too.

Hey guys,

I installed latest version of Transmission yesterday using Optware to my RT-N66U router with Merlin build 3.0.0.4.270.26 and it runs okay for a while. After some time though (when I have active torrents), the web ui ends up with 404 - Not Found. I read somewhere than this can be an issue with too many open files but it doesn't say that in the page.

Any ideas?

 

[TeHashX]

Transmission web ui or router web ui is inaccessible?

 

[Digital Anomaly]

My Transmission Web UI dies. When I had no torrents running, it was fine. With torrents, after a couple of minutes or hours, the Transmission web UI would die.

 

[TeHashX]

I suggest you to try entware version because some file on optware are obsolete.

Oh well, looks like I have to switch to Entware. I'll report back here on my progress when I can.

 

[TeHashX]

Another alternative could be a schedule transmission restart with init-start script

 #!/bin/sh
cru a ScheduledRestartTransmission "0 * * * * /opt/etc/init.d/S95transmission restart"

This script will restart transmission every hour, if you want to change frequency use this generator http://www.openjs.com/scripts/jslibrary/demos/crontab.php

Any ideas?

As long as torrent client is very resources hungry application, we must reduce its appetite Please, stop transmission and edit config file. In Entware I've included fixed settings.json. Here is explanation for all config strings:

• "download-queue-enabled": true, and "download-queue-size": 5, — download five or less torrents simultaneously,
• "encryption": 0, — prefer unencrypted connection to reduce CPU load,
• "max-peers-global": 80, (or legacy "peer-limit-global": 80, option) — if I remember right, every peer "consumes" ~2MB RAM.
• "utp-enabled": false — because uTP is too heavy for embedded devices.

With this settings transmission will be stable as a rock.

Just one thing left to explain. A new transmission chose number of open files automatically, legacy "open-file-limit": 32, option is out of business. In some rare cases transmission may download content faster then it can be saved to USB drive, for example, when a local peer with 100mbps seeding speed has been found. What will happen? As long as transmission uses memory mapping feature transmission relies on Linux VM which can't handle this situation with too small (by default, 2MB) room to play.

I'm strongly recommend to increase "untouchable memory reserve" from default 2MB to 8MB if you are using torrents by:

echo 8192 > /proc/sys/vm/min_free_kbytes

Just put those string to init script as I do.
