  • Version: 11.15.0, 12.13.0, 13.1.0
  • Platform: AIX 7.2
  • Subsystem: os?

The simple check:

./node -e 'const os = require("os"); const interfaces = os.networkInterfaces(); for (const interface in interfaces) {console.log(interface); const addrs = interfaces[interface]; for (const addr of addrs) {console.log(addr.address)}}'

NodeJS 10.17.0 returns nothing.

NodesJS 11.15.0, 12.13.0, 13.10 return:

      throw new ERR_SYSTEM_ERROR(ctx);
      ^

SystemError [ERR_SYSTEM_ERROR]: A system error occurred: undefined returned undefined (undefined)

}

As a consequence - yarn doesn't work.

    Works for me, and works in our CI. Which doesn't mean it works everywhere, obviously, but I'll need more information. ifconfig -a would help. Do you have interfaces?

    libuv/libuv@810377f is the only sinilar bug I can recall, but it doesn't seem directly related.

    Thanks for the answer. It is AIX 7.2 TL3 SP3 LPAR in IBM cloud. It has interfaces:

    It looks like the problem is in sit0. I removed sit0 and it works (v13.1.0):

    # ./node -e 'const os = require("os"); const interfaces = os.networkInterfaces(); for (const interface in interfaces) {console.>
en0
192.168.2.246
en1
10.0.0.26
lo0
127.0.0.1

    I'll see if I can repro, its probably an assumption far-down that interfaces have IPv4 addresses if they are up.

    Do you have any suggestions on how to create an ifx without an address? If there's a non-destructive way, it would save some time. All the AIX I have access to are remote, so I can't take the addresses off the regular interfaces!

    I could try to take the addr off of my lo0, but I'm a bit worried about bricking the LPAR:

    $ ifconfig -a

    The problem is with interfaces which have IPv6 address, but no IPv4 address.

    The way to create a virtual interface on AIX without any IP (no problems with nodejs):

    mkdev -c if -s VI -t vi -a state='up'

    with IPv6 address but without IPv4 (the error above):

    mkdev -c if -s VI -t vi -a state='up' -a netaddr6='fe80::58b1:b0ff:fee4:5583' -a prefixlen=64

    with IPv6 and IPv4 addresses (no problems):

    mkdev -c if -s VI -t vi -a state='up' -a netaddr6='fe80::58b1:b0ff:fee4:5583' -a prefixlen=64 -a netaddr=172.16.1.1 -a netmask=255.255.255.0

    I think libuv/libuv#2545 should fix this. Would it be possible for you to test it?

    I'm not so deep in details of node.js functionality. How can I test it? Should I first compile libuv and then nodejs? or run some test with libuv?

    roughly:

    git clone node, checkout the branch you want to use, cd ./deps; rm -rf uv; then git clone richards' branch of libuv into deps/uv.

    Follow the standard node.js build instructions after that: https://github.com/nodejs/node/blob/master/BUILDING.md

    @aklyachkin Patch deps/libuv with the changes in that PR and then rebuild Node.js.

    I compiled v13.1.0 and it works:

en2

fe80::fcb1:beff:fe92:636e
sit0
::
lo0

    ifconfig output to compare:

         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

    If you see, it shows all IPv6 addresses correct, but I'm not sure if it is correct to show IPv4 address 0.0.0.0 for en2. It has no IPv4 address. Anyway it works! Thank you @richardlau!
