    Your docker does not have enough entropy as required from ts server.
    You may try to include following to get this problem sorted.
    entropy "-v /dev/urandom:/dev/random"

    -------------
    Creating the licensekey.dat that way is a bit strange. Why don't you just include the original file into your docker?

    Dear dante969,

    first too your question.
    I was not sure if that worked with the switch "-e TS3SERVER_LICENSEPATH=... correctly, chown and chmod were also set wrong, so i created file manually.

    So i like too install this docker image on my Synology DS1817+, how much entropy i must have available?
    Hardwarehost:
    cat /proc/sys/kernel/random/entropy_avail = 249
    Docker TS3Server instance:
    cat /proc/sys/kernel/random/entropy_avail = 173

    Linuxversion:
    Linux version 3.10.105 ([email protected]) (gcc version 4.9.3 20150311 (prerelease) (crosstool-NG 1.20.0) ) #23824 SMP Fri Oct 26 18:32:55 CST 2018

    To use the urandom i need the "rng-tools" on my Diskstation but this isnt official supported.
    I can start the basic license TS3Server, maybe the devs can include a switch to change the entropy?

    Thanks for your support!

    Hi pikniker,
    dante told me take a look at your problem.

    I think you implied that there is no /dev/urandom on you machine, that might very well be the culprit.
    Instead of mounting /dev/urandom as /dev/random into the docker, you might want to try the reverse.
    So the actual solution should be "-v /dev/random:/dev/urandom".

    I also looked at the required amount of entropy need, and while 173 bytes is a rather low amount, it should be enough.

    Hey mmuenchow,

    thanks for your reply.
    Your solution doenst works, the TS3DockerServer crash with the same issue.
    Btw i can use the *random device in the TS3 Docker instance.

    I think this is a security option which one would have to adapt to docker, I see no chance on the admin-side.

    Any other ideas?

    We found something and we may can fix the problem.
    The kernel on your host system is to old (it must be at least version 3.17) or else server 3.5.0 will not run.

    We will add a fix into server 3.6.0 and maybe will release a beta next week for this.
    Meanwhile you can try to update your kernel or use server 3.4.0 instead.
