Linuxbrew Nodejs - Bind to port 80

Question

I want to solve the same problem which has been described in this issue.

Therefore I wanted to execute the following command:

$ sudo setcap cap_net_bind_service=+ep /home/username/.linuxbrew/bin/node

This produced the error:

Failed to set capabilities on file `/home/username/.linuxbrew/bin/node' (Invalid argument)
The value of the capability argument is not permitted for a file. Or the file is not a regular (non-symlink) file

Does this happen because the foldername is .linuxbrew and if yes how do I fix it?

Have you checked if its symlinked? – bluesman Sep 25 '15 at 19:35 — bluesman, Sep 25 '15 at 19:35

It happens because you are trying to run that on a symlink. Try running this instead:

sudo setcap cap_net_bind_service=+ep $(readlink -f ~username/.linuxbrew/node)

Yes you were right. I was too stupid to recognize that /home/username/.linuxbrew/bin/node was a symlink. Thanks for the help. – Haves Oct 14 '15 at 05:02
