Can't start on Ubuntu 18.04 #1050

Closed absudabsu closed 5 years ago

absudabsu commented 5 years ago

I've used Zerotier for a few years, and it has always worked flawlessly installing from the curl/bash script on the website. However, this time on Ubuntu I am having problems starting it up.

meohboy@mypc:~$ sudo systemctl status zerotier-one.service

Any ideas? How do I debug and find the cause?

absudabsu commented 5 years ago

Here's what happens when I call the program directly:

meohboy@mypc:~$ sudo /usr/sbin/zerotier-one
/usr/sbin/zerotier-one: fatal error: cannot bind to local control interface port

Now what?

janjaapbos commented 5 years ago

Looks like you have another program / service that binds to localhost port 9993. Check it with lsof -i :9993

janjaapbos commented 5 years ago

sudo lsof -i :9993

absudabsu commented 5 years ago

This is what I get:

$ sudo lsof -i :9993
COMMAND     PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME

zerotier- 15762 root   21u  IPv4  227711      0t0  TCP mypc:9993 (LISTEN)

Looks reasonable? What now?

janjaapbos commented 5 years ago

Perhaps there is no problem, just systemd thinks there is? Or something else started zerotier-one, before systemd tried to do it?

Does zerotier-cli work correctly? Can you join networks?

absudabsu commented 5 years ago

Unfortunately, no. That's what got me to look at why the service wouldn't run:

$ sudo zerotier-cli
zerotier-cli: missing port and zerotier-one.port not found in /var/lib/zerotier-one
absudabsu commented 5 years ago

I don't see the zerotier network interface either, so maybe that's the problem?

The first interface is a different VPN, and the last one is my wireless card.

janjaapbos commented 5 years ago

Check the full command of the zerotier-one proces you see with lsof. Using the PID (15762 in you case) lsof -a -d txt -p 15762

This will probably show: /usr/sbin/zerotier-one

Looks like you have a broken system. Perhaps the installation of zerotier-one was interrupted, or it is unable to create the /var/lib/zerotier-one directory / files, because of permission issues.

absudabsu commented 5 years ago

Hmm

$ sudo lsof -a -d txt -p 15762
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1547007615/gvfs
      Output information may be incomplete.

zerotier- 15762 root txt    REG   7,15  2021736   14 /snap/zerotier-one/64/usr/sbin/zerotier-one

What do you suggest? Try the bash script again, maybe inside as su ?

janjaapbos commented 5 years ago

..

janjaapbos commented 5 years ago

Oh, you have a snap version installed already

janjaapbos commented 5 years ago

So you should make sure you have the snap bin directory in your path

janjaapbos commented 5 years ago

Snap wil not use /var/lib/zerotier-one, but probably something like /var/snap/lib/zerotier-one.

Anyway, you have a snap version installed and your system user does not have snap in its path.

janjaapbos commented 5 years ago

you can get rid of the snap version with: sudo snap remove zeroteir-one and then install the regular way, as shown on the zerotier download page.

absudabsu commented 5 years ago

You are right! Looks like I might have made a mistake by installing via the Ubuntu software store. FWIW: the snap version does not seem to work properly for me even if installed on a fresh system.

Working now after installing via the bash script, thanks!

aalghooneh commented 2 years ago

Just encountered the same problem, follow everything the JanJaapBos said, and if still problem persist kill the PID and then try again

sushinectar commented 1 year ago

mine after following all the steps continues with the error:

"0 join"

after I try to join some network

szafranski commented 1 year ago

Found the solution: sudo apt remove zerotier* and then curl -s https://install.zerotier.com | sudo bash and then: zerotier-cli join <network_number>
