Transmission on AsusWRT routers through Entware-NG

Transmission is a file sharing program.

When you run a torrent, its data will be made available to others by means of upload.

Any content you share is your sole responsibility.

Optware-NG version here

This version works on all supported routers: RT-N16, RT-N66U, RT-AC66U, RT-AC56U, RT-AC68U, RT-AC87U, RT-AC88U, RT-AC3200, RT-AC5300...

1 - Install Entware-NG from here

2 - Install transmission

opkg install transmission-web transmission-daemon-openssl transmission-remote-openssl

3 - Stop transmission

/opt/etc/init.d/S88transmission stop

4 - Backup standard file settings and create a new optimized one:

mv /opt/etc/transmission/settings.json /opt/etc/transmission/settings.json.backup
cat >> /opt/etc/transmission/settings.json << 'EOF'

Press ENTER
5 -
Start transmission daemon

/opt/etc/init.d/S88transmission start

6 - Open transmission webpage by going to default router ip address and port 9091, ex. 192.168.1.1:9091 (username: admin and password: admin)
The default download folder is on /mnt/sda1/Transmission (will be created automatically with the first downloaded torrent and can be changed editing settings.json file) if your usb disk has a label, change sda1 with the disk label. Be sure transmission-daemon is not running or changes will be overwritten!!!

/opt/etc/init.d/S88transmission stop

7 - With nano you can edit any settings like enable / change username, password:

nano /opt/etc/transmission/settings.json

8 - Save settings with CTRL-O, press ENTER and exit nano with CTRL-X, now start transmission again

/opt/etc/init.d/S88transmission start

9 - Create init-start script for some memory tweaks as suggested by ryzhov_al

nano /jffs/scripts/init-start

#!/bin/sh
echo 524288 > /proc/sys/net/core/rmem_max
echo 524288 > /proc/sys/net/core/wmem_max
echo 8192 > /proc/sys/vm/min_free_kbytes

Save with CTRL-O, press ENTER and exit nano with CTRL-X

Make scripts executable

chmod a+rx /jffs/scripts/*


ACCESS FROM WAN
• If you want to access transmission from WAN like work, school, smartphone, tablet or some other device we need to open the port 9091 but the firmware doesn't allow port forwarding to the router himself, for that we will use firewall-start script on /jffs partition:

Create firewall rules

nano /jffs/scripts/firewall-start

Paste this lines in terminal

#!/bin/sh

iptables -I INPUT -p tcp --destination-port 9091 -j ACCEPT
iptables -I INPUT -p tcp --destination-port 51413 -j ACCEPT
iptables -I INPUT -p udp --destination-port 51413 -j ACCEPT

Save with CTRL-O / Enter / and exit with CTRL-X

Make scripts executable and apply rules

chmod a+rx /jffs/scripts/*
sh /jffs/scripts/firewall-start

Go to YourWanIp:9091 on preferred internet browser or install Transmission Remote GUI

TransmissionRemoteGUI


SWAP FILE (Highly recommended) is created automatically when installing Entware-NG
If transmission crashes sometimes "without reason", most probably router goes out of memory and this can be fixed by creating a swap partition but it's a little bit to complicated for most users and we will create a swap file instead, 512MB is more than enough:

cd /opt
dd if=/dev/zero of=swap bs=1024 count=524288
mkswap swap
chmod 0600 swap
swapon swap

To enable swap file when router booting, add this lines to /jffs/scripts/post-mount script

echo "" >>/jffs/scripts/post-mount
echo "swapon /opt/swap" >>/jffs/scripts/post-mount

To unmount swap add this lines to /jffs/scripts/services-stop script

echo "" >>/jffs/scripts/services-stop
echo "swapoff /opt/swap" >>/jffs/scripts/services-stop

EMAIL NOTIFICATIONS
If you have a slow internet connection and you want to be notified when a torrent has finished downloading, place the folowing script witch I called tmail.sh in /jffs/scripts but first don't forget to fill: SMTP, FROM, TO, USER and PASS with your credentials.
WARNING, may become annoying if you are downloading lots of torrents...

#!/bin/sh

SMTP="your-smtp-server:587"
FROM="your-email-address"
TO="your-email-address"
USER="email-user-name"
PASS="email-password"
FROMNAME="Asus Router"

echo "From: "$FROMNAME"<$FROM>" >>/tmp/tmail.txt
echo "Date: `date -R`" >>/tmp/tmail.txt
echo "" >>/tmp/tmail.txt
echo Transmissionbt has finished downloading "$TR_TORRENT_NAME" on `date +%d/%m/%Y` at `date +%T` >>/tmp/tmail.txt

echo "" >>/tmp/tmail.txtcat /tmp/tmail.txt | /usr/sbin/sendmail -S"$SMTP" -f"$FROM" $TO -au"$USER" -ap"$PASS"

rm /tmp/tmail.txt

Stop transmission daemon, change this two lines in /opt/etc/transmission-daemon/settings.json and start transmission again

"script-torrent-done-enabled": true,
"script-torrent-done-filename": "/jffs/scripts/tmail.sh",


TROUBLESHOOTING

  • Terrarum

    Hi, I think these guides are great!
    However, there seems to be some sort of crash happening sometimes when Transmission is preallocating files, resulting in VPN clients 'Error - authentication failed' and occasionally samba not working. I suspect RT-AC68U is running out of RAM memory. If this is the case, is there another way of optimising the memory besides Ryzhov's example set in this guide?

    • TeHashX

      Yes, create a swap file / partition

      • Terrarum

        2GB swap partition is created and working but I hardly ever noticed more than roughly 26000 used:
        Swap: 1999996 22404 1977592

  • דור גלעם

    Can't get transmission to run a script when a torrent is added/finishes downloading, this is what I did so far:

    Inside my JSON:
    "script-torrent-added-enabled": true,
    "script-torrent-added-filename": "/mnt/sda4/Scripts/torrent_finish.sh",
    "script-torrent-done-enabled": true,
    "script-torrent-done-filename": "/mnt/sda4/Scripts/torrent_finish.sh",

    Contents of torrent_finish.sh:
    #!/bin/bash
    /bin/echo "asdasd" > /mnt/sda4/Scripts/b.txt

    Tried chmod'ing all files inside my Scripts directory several times using chmod 777, chmod +x etc.

    The script is never run and thus the file is never created.

    Also check syslog and transmission log files and both don't show any script being run.

    Any ideas?

    • I'm not sure if "script-torrent-added-filename" is a valid option but "script-torrent-done-enabled" yes.
      You have to modify your script from #!/bin/bash to #!/bin/sh and try to execute first from terminal to see if is ok
      sh /mnt/sda4/Scripts/torrent_finish.sh

      • דור גלעם

        Wow, changing it to #!/bin/sh actually worked!
        Thanks A LOT!

  • TAKA

    How can I use command "transmission-remote"?
    To use script on Transmission, I need to access "transmission-remote".
    When I type the command, -sh: transmission-remote: not found is shown.

    • opkg install transmission-remote-openssl

      • TAKA

        Thanks for your support. Now it works fine :D

  • Marcos

    Hi, I configured Transmission like said, and added the policies in the Firewall but I don't have access from Internet. I really like how works Transmission and would like to solve this problem.

    Thanks

    • TeHashX

      Do you have a fixed or dynamic ip?

      • Marcos

        I have Dynamic IP, but that's not the problen because i use No-IP.
        Aicloud from ASUS works perfectly
        And more things I have access from Internet
        Maybe it's a problem from the Router, because I have opened SSH acces from WAN and couldn't connect

        • TeHashX

          Which router, firmware?

          • Marcos

            380.61 Merlin

          • TeHashX

            Go to http://www.canyouseeme.org/ and check if ports 51413 & 9091 are open.

          • Marcos

            Tested!! The two ports report the same, telling that there is no service.

            But I could downland without any problem

            And the policies for firewall are added like said here

          • TeHashX

            Try one thing, go to router ui / Firewall / NAT Loopback and choose Merlin then reboot router

          • Marcos

            Done!! But nothing :(

          • TeHashX

            Can I assist you through team viewer?
            Send me tw id and temp password https://www.hqt.ro/contact/

          • Marcos

            Thanks a lot. Now I'm not in home. I will be in home at 18h hour of Spain.
            At what time could you assist me?

          • TeHashX

            GMT +3 here, just let me know when you are home.

          • Marcos

            I'm Home now. Are you there?

          • Marcos

            Thanks a lot for the Help TeHashX

  • TeHashX

    opkg install transmission-daemon-openssl

    • Yong

      Thanks TeHashX!
      This is just what I needed!

    • Guido

      Thanks! That's works for me! :)

  • Yong

    Hi!

    I'm having some problems installing transmission. Right after step 2, this file does not exist : "/opt/etc/init.d/S88transmission"

    • TeHashX

      ls -l /opt/etc/init.d

  • TeHashX

    Modified settings.json to be created instead of downloading from hqt server at point 4

  • Guido

    Hi! I do not know how but my "cd /opt/etc/transmission/" is empty all files was deleted.

    [code]
    elrengo@RT-AC3100:/tmp/home/root# cd /opt/etc/transmission/
    elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm/etc/transmission# ls -l
    elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm/etc/transmission#[/code]

    I would like to download the new config and do not works:

    [code]
    elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm/etc/transmission# wget -c -O /opt/etc/transmission/settings.json http://goo.gl/KKCxTx
    /opt/etc/transmission/settings.json: Input/output error
    elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm/etc/transmission#
    [/code]

    and I do not know if need some extra file. I'm in doubt to remove and re install transmission.

    • TeHashX

      How many usb disks and partition do you have connected to the router?
      I see entware is installed to /mnt/sda2/, if you reboot router the /opt partition is still /sda2?
      Input/output error has to do something with your disk not the script, which is fine, try oppening manually by clicking on http://goo.gl/KKCxTx

      • Guido

        Thanks! For you reply. I have two USB ports. USB3 port has a one drive with only a ntfs filesystem who is used to shared my photo backup. In usb 2 port I have one drive with two filesystem the first is a SWAP filesystem the other a ext4 filesystem.

        elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm/etc/transmission# mount
        rootfs on / type rootfs (rw)
        /dev/root on / type squashfs (ro,relatime)
        devtmpfs on /dev type devtmpfs (rw,relatime,size=257528k,nr_inodes=64382,mode=755)
        proc on /proc type proc (rw,relatime)
        tmpfs on /tmp type tmpfs (rw,relatime)
        sysfs on /sys type sysfs (rw,relatime)
        devpts on /dev/pts type devpts (rw,relatime,mode=600)
        /dev/mtdblock4 on /jffs type jffs2 (rw,noatime)
        usbfs on /proc/bus/usb type usbfs (rw,relatime)

        elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm/etc/transmission#

        Allways when I can monitorin the /opt whas in sda2 filesystem. When I run "cd /opt" go to:

        elrengo@RT-AC3100:/# cd /opt/
        elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm# pwd
        /opt
        elrengo@RT-AC3100:/tmp/mnt/sda2/entware-ng.arm#

        When I check the short url: "http://goo.gl/KKCxTx" go to this url: "http://files.hqt.ro/transmission/settings.json" with 404 error not found: The requested document was not found on this server. Web Server at hqt.ro

        • TeHashX

          It's better to label the disk and will be mounted always by that label
          tune2fs -L "desired_label" /dev/sda2
          reboot
          Now reinstall entware or optware

          When I check the short url: "http://goo.gl/KKCxTx" go to this url: "http://files.hqt.ro/transmission/settings.json" with 404 error not found: The requested document was not found on this server. Web Server at hqt.ro

          I deleted that file from server, now you should create it manually as described at point 4

          • Guido

            Thanks for you reply! Ok. I backup all my data download with Transmissión and re-install my NG of Entware and then re install transmission.

          • Guido

            Looking for a manual of tune2fs, I can see that commando not format my filesystem. When I nee to reinstall entware, I need to delete it before or reinstall with out touch the actual version installed. If I need to uninstall it, how I can uninstall it. Again thanks in advance!

          • TeHashX

            Run installer again, this will backup existing optware/entware, don't have to format usb, but first give a label with command
            tune2fs -L "desired_label" /dev/sda1
            reboot
            Run point 4 from here https://www.hqt.ro/how-to-install-new-generation-entware/

          • Guido

            I do not know why but after a reboot I lost all my data in the disk and include all movies and series download by transmission. After swapon /dev/sda1, after reboot never mount the disk by auto.
            I try to recover the info using test disk but it no have ext4 undelete feature.I will be reassigned to lost all of them.

          • TeHashX

            If you have a swap partition and not a file, modify /jffs/scripts/post-mount script.
            Did you labeled partitions?

          • Guido

            Thanks. Yes, I have a swap partition / filesystem. sda1 is Linux Swap filesystem, sda2 is Ext4 filesystem. At the end of /jffs/scripts/post-mount script I added swapon /dev/sda1.

          • TeHashX

            But first you have to enable swap
            swapoff /opt/swap
            rm /opt/swap
            mkswap /dev/sda1
            swapon /dev/sda1

          • Guido

            before reboot, I do:
            mkswap /dev/sda1
            swapon /dev/sda1
            after reboot I put at the end /jffs/scripts/post-mount script swapon /dev/sda1.

          • TeHashX

            Ok, and?

          • Guido

            And not mount it automatically. And I do not found the information. Now I can start again the prosess. I'm not in my house to work with it.

          • Guido

            Hi again! I do not know how but when I create a swap, I run: "mkswap /dev/sda2".

            Now I can format again sda2 to ext 4. I install all again from begening. First entware-ng an then some applications that I use, unrar, 7-zip and mc. Then I installed:

            elrengo@RT-AC3100:/tmp/etc# ls

            elrengo@RT-AC3100:/tmp/etc#

            I do not found the services, the directorys and other settings of transmission.

            I installed again from beginning creating mkfs.ext4, then intalling again entware, then transsmission web but I have the same issue. :S

          • Guido

            What log I need to view or share with here to resolve the issue?

          • TeHashX

            Install transmission-daemon ssl
            opkg install transmission-daemon-openssl

          • Guido

            I do not read these mensage. I overlook it

      • Guido

        I found this error because I can not access to web gui for transmission with the following error:

        403: Forbidden

        Unauthorized IP Address.

        Either disable the IP address whitelist or add your address to it.

        If you're editing settings.json, see the 'rpc-whitelist' and 'rpc-whitelist-enabled' entries.

        If you're still using ACLs, use a whitelist instead. See the transmission-daemon manpage for details.

        When I went to search the configs file I do not find it.

        • TeHashX

          I modified point 4

    Hi,

    just discovered this in the log, maybe you have an idea how to fix it.

    I'm running Merlin Firmware:380.59 AC87U router.

    Thanks

    Hi TeHashX,

    A little bit confused regarding the swap part.

    During the Entware-NG install, I have selected to have 2048 MB space of swap. Its there.

    total used free shared buffers
    Mem: 255692 111416 144276 0 1188
    -/+ buffers: 110228 145464
    Swap: 2097148 0 2097148

    but on this page, even if I have the swap file, you are saying that we still need a 512 MB file, so I've tried to follow your commands

    cd /opt
    dd if=/dev/zero of=swap bs=1024 count=524288
    mkswap swap
    chmod 0600 swap
    swapon swap

    Issuing dd if=/dev/zero of=swap bs=1024 count=524288 I hit the dd: can't open 'swap': Text file busy.

    I assume this error is because a have the 2048 Mb file in /opt.

    Any feedback?

    Thanks

    • TeHashX

      You already created swap, don't need one more time

      • Adrian

        ok, thanks

        Another question if you can help.

        Entware-NG in a USB memory stick that is permanently plugged into the router.
        Every time, i'm restarting the router, checking with "mount" I can see that the USB stick is /dev/sdc5 or /dev/sdb5 or /dev/sde5 and so on.

        Any idea why I have different values with every mount? Its causing me trouble because at this point is mounted and visible but cannot run NANO, MC or other packages installed...

        Thanks

        • Adrian

          i assume that if now it is /dev/sdc5 it cannot see the /opt file since the post-mount is saying:

          if [ "$1" = "/tmp/mnt/sdb5" ] ; then
          ln -nsf $1/entware-ng.arm /tmp/opt

          its still searching for sdb5

        • TeHashX

          Give usb a label then install optware/entware from scratch

          tune2fs -L "desired_label" /dev/sda1
          Change sda1 with usb disk mount, in your case sdb5

          https://www.hqt.ro/how-to-format-usb-drive/

          • Adrian

            sorry to ask but I've just installed Entware from scratch today. Can't I just put the label and then modify the post post-mount script with the new label?
            Maybe there is an workaround ...

          • TeHashX

            The answer is yes :)

          • Adrian

            Thanks it worked.

            Getting back on the swap topic, when I have started some torrents, I can see in the routers log a lot of warnings

            swapoff /opt/swap
            rm /opt/swap
            Create swap file again with instructions at the end of post

          • Adrian

            Perfect ! no more swap errors. I will create an Wikipedia page for you :))

    Hi! How I can add samba share the path "/mnt/sda2/Transmission" because is a EXT4 Filesystem and file that are compressed I can see. How I stop samba, modify smb.conf and start to add this share to network and not use the ftp.
    Thanks.

    • TeHashX
      • Guido

        Hi create the file /jffs/configs/smb.conf.add with:

        [Transmission]
        comment = Files download by Transmission.
        path=/mnt/sda2/Transmission
        dos filetimes = yes
        fake directory create times = yes
        valid users = elrengo
        invalid users =
        read list = elrengo
        write list = elrengo

        and works!!

        • TeHashX

          It's not the same result as enabling from router ui?

          • Guido

            I do not enable the NFS share. I share with samba and I can now navigate from explorer.

    Hi! I have a RT-AC3100. I have 2 hdd mounted.USB 3 have a sony 1TB NTFS hdd, usb 2 have a 500GB 1GB swap partition that is not possible to configure to swapon at boot. but I create a swap file using the step on this man. Whe I installed and go to web that is the error:

    • TeHashX

      I will try to install transmission through entware later today and I will provide you a solution.

      • TeHashX

        I just installed entware-ng and transmission from scratch on my RT-AC68U and it's all fine.
        You messed something, try to install again.

        • Guido

          Thanks for your quicky reply. I found something with entware installation. After a reboot, when I put cd /opt the path is not de /dev/sda2 with /tmp/mnt/download the device with EXT4 file system go to HDD with NTFS file system How I can do a unistall all to re-install from scratch.
          If I remove both drives, format again with ETX and create swap file and intall from zero works, do not have any issue?
          Thanks in advance!!

          • TeHashX

            Try installing entware-ng from scratch using this guide https://www.hqt.ro/how-to-install-new-generation-entware/ not the entware-setup.sh script included in the firmware, if your ext4 disk has the label "download" will be always mounted right and entware should be ok.
            You can use your swap partition instead of swap file
            use fdisk -l to see which one is (ex. /dev/sdb2)
            run mkswap /dev/sdb2
            swapon /dev/sdb2
            To mount at boot add to /jffs/scripts/post-mount script swapon /dev/sdb2
            :)

          • Guido

            Hi! I'm very grateful with your help. I realy want to do a new install from scratch of entware and transmission. For that I would like to know if need it some step by special to uninstall it. I was thinking at first time format a JFFS to delete all manual script added. Then umount and unconnect both HDD. Delete all data from both an start from there. That proccess is correct?

            My download hdd was /dev/sda2, /dev/sda1 it is my swap partition. When I delete I have a doubt to continue with EXT4 filesystem or change it for EXT3 filesystem. What is better?

            Talking about SWAP I am thinking to remove the partition and create a new file with the step of new install entware. If you recommend still to use a swap parition I need to add the swapon command in "/jffs/scripts/post-mount" script and swapoff in "/jffs/scripts/services-stop". Both script have a if sentece, I do not know what to do this sentence. I add the command at the end of both scripts or inside the if sentence.

            Thanks in advance again!!

            :)

          • TeHashX

            Leave it as ext4
            Delete all jffs scripts if you don't have anything important there.
            It's better a swap partition
            Leave both drives connected and reboot 2-3 times to see if are mounted with the same letter.
            I don't have time right now but I will make a guide about how to mount by label swap partition at boot.

          • Guido

            Thanks! I will try with that you say. I do not have enythin in jffs scripts because it the only that I installed.

          • Guido

            At this time is working! Thanks! I only have a doubt with swap at start and script for firewall start if I need to call it in one of start scripts.

          • Guido

            Hi! I'm again. :) I delete all of both drives and format. Create a Swap partition and activate. downlaod now is mounted as "/dev/sda2 on /tmp/mnt/sda2 type ext4 (rw,nodev,relatime,user_xattr,barrier=1,data=ordered)" the download label I delete by error.

            When I want to add:

            To mount at boot add to /jffs/scripts/post-mount script swapon /dev/sdb2

            I found in the script that:

            "elrengo@RT-AC3100:/jffs/scripts# vi ./post-mount
            #!/bin/sh

            if [ "$1" = "/tmp/mnt/sda2" ] ; then
            ln -nsf $1/entware-ng.arm /tmp/opt
            fi

            sleep 2
            if [ -f /opt/swap ]
            then
            echo -e "Mounting swap file..."
            swapon /opt/swap
            else
            echo -e "Swap file not found or /opt is not mounted..."
            fi"

            I'm thinking to add to the last of scrips because the scrip do reference to swap file.

  • Tayshawn

    server is not responding... cannot download transmission-web. any advice?

  • Michal Wheelq

    How do I make it start after reboot? currently it doesnt start :/

    • Your drive is mounted after services are started.
      Add this lines at the end of /jffs/scripts/post-mount

      sleep 30
      /opt/etc/init.d/S88transmission restart

      • Michal Wheelq

        any reason why S88 script is not being picked up automatically by rc.unslung

        • Did you tried command /jffs/scripts/services-start and it's not working?

          • Michal Wheelq

            yes. only adding lines at the end of /jffs/scripts/post-mount

            sleep 30
            /opt/etc/init.d/S88transmission restart

            works. why isn't this picked up automatically

          • Something is changed in latest firmwares and services are started before usb disk is mounted. Anyway if alternative works, you are ok. :)

  • mPolr

    If i install entware on internal microsd (at RT-N66U) can i download torrents to external USB-HDD formatted NTFS?

    • Technically is posibile but practically not quite, why don't you try and share results?

  • Al

    My transmission does not start upon reboot of the router. I also noticed that in this post there is no line for autostart of the app. In the post of optware transmission there was line "app_set_enabled.sh transmission yes", but not here.

    Have I missed something?

    • Add "/opt/etc/init.d/S88transmission start" to your startup scripts.

    Hi. I have a problem with a swap on RT-N66U Marlin firmware 378.51. Its already installed by all instruction

    cd /optdd if=/dev/zero of=swap bs=1024 count=524288
    mkswap swap
    chmod 0600 swap
    swapon swap

    swapon /opt/swap in /jffs/scripts/post-mount

    and working well

    Swap: 524280 4204 520076

    But after rebooting its lost and view like swap 0 0 0

    Help please :)

    • Dmytro

      :( please

      • Hmmm, add sleep 30 before swapon /opt/swap

        sleep 30

    I am using this on my RT-AC66U. I have a Mac. I am using a Seagate Expansion HDD (1TB) formatted to Ext3. Transmission is running smoothly. The only problem I encounter is that my Mac is not detecting the drive. Whenever I try to connect to the server I am getting Connection Failed. Pls help!

      hi,you must enable file share service(eg,ftp/samba)then,open finder,command+k,type your router ip。enjoy it。
      sorry for my bad English ;)

    Does this guide work for Entware on ARM devices (i.e. AC68P)? Thanks.

    Hi, sorry for bad english. A i have an rt-n66u and merlin's last firmware, after i am installing entware and transmission all is going fine for a long time, but when i need to power off router my transmission didn't start again and i need to reinstall entware and transmission... help please

    • You don't need to reinstall all every time :(
      Setup jffs partition, put a file or an empty folder inside and reboot router 2-3 times, now check if that file or folder it's stil there

      • Kevin170293

        Sorry, that was my FAIL. I didn't check that checkbox 'Enable JFFS custom scripts and configs' thanks for helping

  • RyanAir

    transmission daemon doesn't start on mu RT-AC68U and I have no idea why...

    • 1 - you didn't enabled swap
      2 - where did you set download folder?
      3 - Send me Team Viewer id and temp password by contact form https://www.hqt.ro/contact/

      • RyanAir

        hey, thank you for the answer, transmission (from the Optware repository) has always properly worked on my RT-AC68U without any swap files or partitions, it has 256 MB RAM...The download folder is set to /tmp/mnt/Volume/transmission/download

      • RyanAir

        Finally it was the missing swap file. Who knows why.. Thank you.

      • RyanAir

        Although a swap file seems to help, I still cannot imagine why. "Free" says, that swap is always unused, even if transmission is running, even if transmission leeching and seeding torrents. So it seems to be a particularity of implementation within Entware on ARM?

        • With free command you get 0 0 0?

          • RyanAir

            not 0 0 0!

          • It's ok, try adding more torrents and will be used for sure.

  • Alexey Tsapko

    Should I make SWAP file if I have already done when installing Wheezy?

  • zikiman

    hello,

    I have a router asus rt-n66u I installed merlin, entware and transmission. I followed the tutorials and the transmission works but slow. The cpu with 1 file downloading is set to 100%. Any suggestions ??

    thank you very much

    regards

    • A swap file will help

      • zikiman

        Now I'm formatting the hard disk usb and start the installation clean. I return to install merlin, entware and transmission, or better consider another alternative. Thank you for your quick response.

        PS factory reset router, combination of buttons?

        • Press reset button for about 30 sec.
          You can try debian version (not posted tutorial yet for mipsel devices) but anyway, transmission will use a lot of cpu, it's normal.

          • zikiman

            then it is normal that the cpu is at 100% all the time? buff. downloads are very slow ... I'll have to rescue my old NAS ... but first try what you told me.

            Thank you

  • Ramasjang

  • nick
