Permission denied (os error 13)

Support

I need some help here running a node.
I’m getting a “Permission denied (os error 13)”.

$ sn_node -vv --idle-timeout-msec 5500 --keep-alive-interval-msec 4000 --skip-igd --first --local-addr 127.0.0.1:1
Starting logging to stdout
Error:
   0: Cannot start node. If this is the first node on the network pass the local address to be used using --first

   2: Cannot connect to the endpoint: Failed to bind UDP socket
   3: Failed to bind UDP socket

$ sn_node --version
safe_network 0.31.39

Is sn_node supposed to run with root priviliges?

sn_node should run fine as a non-root user.
I have seen this error before but I “solved” it by dropping back to an older version of sn_node.

Looks like this can be solved by going all the way back to Version 0.30.0, so around fifty releases earlier.

It may be a source of problem.

Possibly “worked around” rather than “solved” as I have had later releases seemingly working OK.

Well port 1 isn’t exactly the standard port for maidsafe nodes, although it was the port I would see when running baby fleming in the latest version.

If you mean the IP port then it has to be over 1024 as below that you need root access.

I suspect the confusion is over @Vort’s use of :1 to signify point number one in the original list of errors although if sn_node is really attempting to use port 1 then naturally root access is req’d and we have a problem with a daft port no being allocated

I just got this error with sn_cli 0.38.0 and safe_network 0.32.0

Run with COLORBT_SHOW_HIDDEN=1 environment variable to disable frame filtering.

EDIT: building 0.31.9 now and I’ll try again.
