I am trying to setup Dante SOCKS server on my Raspberry 3. I tried a clean install of Debian Buster and Ubuntu 19.10. On both systems I get the following error right after server installation with the default config: 

ubuntu@ubuntu ~> sudo systemctl start danted
Job for danted.service failed because the control process exited with error code.
See "systemctl status danted.service" and "journalctl -xe" for details.
ubuntu@ubuntu ~> sudo systemctl status danted
● danted.service - SOCKS (v4 and v5) proxy daemon (danted)
   Loaded: loaded (/lib/systemd/system/danted.service; enabled; vendor preset: enabled)

     Docs: man:danted(8)
           man:danted.conf(5)

Mar 19 18:04:15 ubuntu systemd[1]: Starting SOCKS (v4 and v5) proxy daemon (danted)...

Mar 19 18:04:15 ubuntu systemd[1]: Failed to start SOCKS (v4 and v5) proxy daemon (danted).

Output from Ubuntu v19.10, Dante v1.4.2
What can I do to solve this issue?

Update: I had Dante working on one of previous versions of Debian (probably Stretch) on the same device

  • I have the same problem. Don't want to go back on a previous version of Raspbian. Does anyone have an idea? – vigilian Apr 22 '20 at 22:38

edit the file

 sudo vim /lib/systemd/system/danted.service

find the line

ReadOnlyDirectories=/bin /etc /lib /lib64 /sbin /usr /var

and change /lib64 to -/lib64

ReadOnlyDirectories=/bin /etc /lib -/lib64 /sbin /usr /var

save (ctrl+x y enter) now run

sudo systemctl daemon-reload
sudo /etc/init.d/danted start

this was suggested by Anatoly A. Kazantsev at https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1688336.html

some debian distros don't have the /lib64 folder.

For what I've seen in different project, it seems to be a badly packaged version. So we need to make a ticket with debian/ubuntu/Raspbian about this packet to warn the maintainers. In the mean time, here is a partial solution that I've retrieved from here. You can start danted as a simple process.

sudo danted

You can maybe use a bash script in the mean time by including it in screen/tmux session.
