[Linux] Network module shows offline all the time

[presianbg]

Hi,

Great project.
The network module seems to not working in Solus Linux. It shows "OFFLINE" all the time.
Detected NICs are correct + ping to 1.1.1.1 is OK.
Changing the LAN to WLAN and the address for test is not giving any different results.
My public IPv4 address is blinking.

Is there a way to debug and troubleshoot this issue? I'm running it from AppImage.

Could you give me a list of your NICs?
Do you think you could have any latency issues reaching https://ipinfo.now.sh?
Do the 3D globe and network traffic monitor work or are they blinking/displaying "offline"?

3D globe and network traffic monitor are showing OFFLINE too.

EDIT: I understand most of the code (haven't write a single line in JS though), but this part of the netstat class does not make sense to me:

            if (net.ip4 === "127.0.0.1") {
                offline = true;

I assume the while loop does not pick my local network and the above case sets the offline flag.

[GitSquared]

The part of netstat that loops through NICs to try to find the correct one will return the loopback interface if it hasn't found anything better.
If after selecting a network interface, its IP address matches localhost, the code concludes that no externally connected interface was found, and so flags the system as offline.

There should be a tiny text in the top right corner of the netstat module indicating the interface it's trying to monitor. Can you confirm that's the right one?

Seems like you got multiple addresses linked to that interface, and I'm not quite sure how the JS code is handling that.

Try opening the dev tools in eDEX (Ctrl+Maj+I), clicking on the "console" tab and running this:
window.si.networkInterfaces(d => console.log(JSON.stringify(d, 0, " ")))

Copy/paste the JSON output here please. Also, it would be helpful if you could run it a few times and check if the output is consistent - notably in the ip4/ip6 fields.

[presianbg]

Hi,

The output is consistent:

[
 {
  "carrierChanges": 0,
  "duplex": "",
  "iface": "lo",
  "ifaceName": "lo",
  "internal": true,
  "ip4": "127.0.0.1",
  "ip6": "::1",
  "mac": "",
  "mtu": 65536,
  "operstate": "unknown",
  "speed": -1,
  "type": "virtual"
 },
 {
  "carrierChanges": 4,
  "duplex": "",
  "iface": "wlp1s0",
  "ifaceName": "wlp1s0",
  "internal": false,
  "ip4": "172.16.16.29",
  "ip6": "2001:REDACTED:b8f1",
  "mac": "REDACTED:96:71:9d",
  "mtu": 1500,
  "operstate": "up",
  "speed": 866.7,
  "type": "wireless"
 }
]

Okay, all good so far.

Can you give me the output of the following command in eDEX's dev console?

output = {iface: window.mods.netstat.iface, internalIPv4: window.mods.netstat.internalIPv4, externalIPinfo: window.mods.netstat.ipinfo, lastReachFinished: window.mods.netstat.lastconn.finished, lastReachHeader: window.mods.netstat.lastconn._header, offlineVerdict: (window.mods.netstat.offline) ? "offline" : "online"};console.log(JSON.stringify(output, 0, " "));

@GitSquared, thanks for your time and effort for solving this.

It looks right to me, except the "offlineVerdict" value 👎

{
 "iface": "wlp1s0",
 "internalIPv4": "172.16.16.29",
 "externalIPinfo": {
  "geo": {
   "latitude": 42.6833,
   "longitude": 23.3167,
   "metro_code": null,
   "time_zone": "Europe/Sofia"
  },
  "ip": "Public IP REDACTED"
 },
 "lastReachFinished": true,
 "lastReachHeader": "GET / HTTP/1.1\r\nHost: ipinfo.now.sh\r\nConnection: keep-alive\r\n\r\n",
 "offlineVerdict": "offline"
}

[GitSquared]

Indeed. I'm going to continue investigating this tomorrow, hopefully i'll have something for you.

[GitSquared]

@presianbg Could you try this test version? I'm exactly sure it will fix the problem but doesn't hurt to try.

[presianbg]

Same result + the file system widget is stuck on "Calculating Available Space..."

[GitSquared]

Seems like a case of #446 on linux too... Well that one at least will be easy to fix. Gonna have to try something else to fix your original issue though. Hang tight!..

[GitSquared]

@presianbg How about this one?

[presianbg]

Works flawlessly :) Thanks!
