no ip_unprevileged_port_start found on Debian

Hi,

trying this out but it's not working on Debian 9.9.

   😇    ❨site.js❩ Linux: about to disable privileged ports so we can bind to ports < 1024.
         ❨site.js❩ For details, see: https://source.small-tech.org/site.js/app/-/issues/169
sysctl: cannot stat /proc/sys/net/ipv4/ip_unprivileged_port_start: No such file or directory

   ❌    ❨site.js❩ Error: Could not disable privileged ports. Cannot bind to port 80 and 443. Exiting. Error: Command failed: sudo sysctl -w net.ipv4.ip_unprivileged_port_start=0
sysctl: cannot stat /proc/sys/net/ipv4/ip_unprivileged_port_start: No such file or directory

Ok so I uninstalled this and tried installing with npm. It does install, but then when running site.js update, it says

Thanks for the report. I’ll install a Debian image and test this out and see if I can reproduce it and report back.

Hi @kapitaali,

I just did the following and could not reproduce your error:

• Installed latest Debian (10/buster).
• Added my non-privileged account to sudoers as the Debian installer didn’t do this automatically for me.
• In my non-privileged account, installed wget as Debian has neither wget or curl installed by default apparently. (sudo apt install wget)
• Ran the Site.js installation command from sitejs.org. (wget -qO- https://sitejs.org/install | bash)
• Created a simple site

  mkdir -p sandbox/hello-world
  echo 'Hello, world!' > sandbox/hello-world/index.html
  site sandbox/hello-world

And Site.js initialised and started serving the site at https://localhost without error.

I’m wondering what about your configuration is causing the issue.

A couple of questions:

1. Did you change the permissions for sysctl (perhaps as part of hardening your system?)
2. What command did you use to run Site.js via npm?

Thanks.

Hi,

1. no, did not touch sysctl, it is as it is
2. used npm i -g @small-tech/site.js to install it and then site.js sandbox/hello-world to execute it

After having created the directories like you did, and having run the command site.js sandbox/hello-world I get an error:

   ❌    ❨site.js❩ Error: Could not disable privileged ports. Cannot bind to port 80 and 443. Exiting. Error: Command failed: pushd /home/linuxbrew/.linuxbrew/lib/node_modules/@small-tech/site.js > /dev/null; git log -1 --oneline

2. used npm i -g @small-tech/site.js to install it and then site.js sandbox/hello-world to execute it

   ❌    ❨site.js❩ Error: Could not disable privileged ports. Cannot bind to port 80 and 443. Exiting. Error: Command failed: pushd /home/linuxbrew/.linuxbrew/lib/node_modules/@small-tech/site.js > /dev/null; git log -1 --oneline

I’ve reproduced this second error by attempting to run Site.js via npx (basically equivalent to what you were doing).

Tracking internally here: https://source.small-tech.org/site.js/app/-/issues/250

The fix will be in the next release.

Thank you again for reporting this and apologies for the hassle. Since I’m either running it during development from my local git working directory or via the binary in production, I hadn’t considered this use case.

[aral]

@kapitaali I just released version 16.0.1 that fixes your second issue. You should be able to run Site.js as a global module now and also, if you like, through npx. Thank you again for your help :)

[kapitaali]

I have confirmed on my other system that it does in fact work with npm. This one needs inspecting, but it's not the site.js itself that is broken here. So thanks.
